The Next Society

The new economy may or may not materialize, but there is no doubt that the next society will be with us shortly. In the developed world, and probably in the emerging countries as well, this new society will be a good deal more important than the new economy (if any). It will be quite different from the society of the late 20th century, and also different from what most people expect. Much of it will be unprecedented. And most of it is already here, or is rapidly emerging.

In the developed countries, the dominant factor in the next society will be something to which most people are only just beginning to pay attention: the rapid growth in the older population and the rapid shrinking of the younger generation. Politicians everywhere still promise to save the existing pension system, but they--and their constituents--know perfectly well that in another 25 years people will have to keep working until their mid-70s, health permitting.

What has not yet sunk in is that a growing number of older people--say those over 50--will not keep on working as traditional full time nine-to-five employees, but will participate in the labor force in many new and different ways: as temporaries, as part-timers, as consultants on special assignments, and so on. What used to be personnel and are now known as human resources departments still assume that those who work for an organization are full-time employees. Employment laws and regulations are based on the same assumption. Within 20 or 25 years, however, perhaps as many as half the people who work for an organization will not be employed by it, certainly not on a full-time basis. This will be especially true for older people. New ways of working with people at arm's length will increasingly become the central managerial issue of employing organizations, and not just of businesses.

The shrinking of the younger population will cause an even greater upheaval, if only because nothing like this has happened since the dying centuries of the Roman Empire. In every single developed country, but also in China and Brazil, the birth rate is now well below the replacement rate of 2.2 live births per woman of reproductive age. Politically, this means that immigration will become an important and highly divisive issue in all rich countries. It will cut across all traditional political alignments. Economically, the decline in the young population will change markets in fundamental ways. Growth in family formation has been the driving force of all domestic markets in the developed world, but the rate of family formation is certain to fall steadily unless bolstered by large-scale immigration of younger people. The homogeneous mass market that emerged in all rich countries after the Second World War has been youth-determined from the start. It will now become middle-age-determined, or perhaps more likely it will split into two: a middle-age-determined mass market and a much smaller youth-determined one. And because the supply of young people will shrink, creating new employment patterns to attract and hold the growing number of older people (especially older educated people) will become increasingly important.

Knowledge is all

The next society will be a knowledge society. Knowledge will be its key resource, and knowledge workers will be the dominant group in its workforce. Its three main characteristics will be:

· Borderlessness, because knowledge travels even more effortlessly than money.

· Upward mobility, available to everyone through easily acquired formal education.

· The potential for failure as well as success. Anyone can acquire the "means of production",

i. e, the knowledge required for the job, but not everyone can win.

Together, those three characteristics will make the knowledge society a highly competitive one, for organizations and individuals alike. Information technology, although only one of many new features of the next society, is already having one hugely important effect: it is allowing knowledge to spread near-instantly, and making it accessible to everyone. Given the ease and speed at which information travels, every institution in the knowledge society--not only businesses, but also schools, universities, hospitals and increasingly government agencies too-- has to be globally competitive, even though most organizations will continue to be local in their activities and in their markets. This is because the Internet will keep customers everywhere informed on what is available anywhere in the world, and at what price.

This new knowledge economy will rely heavily on knowledge workers. At present, this term is widely used to describe people with considerable theoretical knowledge and learning: doctors, lawyers, teachers, accountants, chemical engineers. But the most striking growth will be in "knowledge technologists" ~ computer technicians, software designers, analysts in clinical labs, manufacturing technologists, paralegals. These people are as much manual workers as they are knowledge workers; in fact, they usually spend far more time working with their hands than with their brains. But their manual work is based on a substantial amount of theoretical knowledge which can be acquired only through formal education, not through an apprenticeship. They are not, as a rule, much better paid than traditional skilled workers, but they see themselves as "professionals" . Just as unskilled manual workers in manufacturing were the dominant social and political force in the 20th century, knowledge technologists are likely to become the dominant social--and perhaps also political--force over the next decades.

The new protectionism

Structurally, too, the next society is already diverging from the society almost all of us still live in. The 20th century saw the rapid decline 'of the sector that had dominated society for 10,000 years: agriculture. In volume terms, farm production now is at least four or five times what it was before the First World War. But in 1913 farm products accounted for 70% of world trade, whereas now their share is at most 17%. In the early years of the 20th century, agriculture in most developed countries was the largest single contributor to GDP; now in rich countries its contribution has dwindled to the point of becoming marginal. And the farm population is down to a tiny proportion of the total.

Manufacturing has traveled a long way down the same road. Since the Second World War, manufacturing output in the developed world has probably tripled in volume, but inflation adjusted manufacturing prices have fallen steadily, whereas the cost of prime knowledge products-health care and education-has tripled, again adjusted for inflation. The relative purchasing power of manufactured goods against knowledge products is now only one-fifth or one-sixth of what it was 50 years ago. Manufacturing employment in America has fallen from 35% of the workforce in the 1950s to less than half that now, without causing much social disruption. But it may be too much to hope for an equally easy transition in countries such as Japan or Germany, where blue-collar manufacturing workers still make up 25--30% of the labor force.

The decline of farming as a producer of wealth and of livelihoods has allowed farm protectionism to spread to a degree that would have been unthinkable before the Second World War. In the same way, the decline of manufacturing will trigger an explosion of manufacturing protectionism-even as lip service continues to be paid to free trade. This protectionism may not necessarily take the form of traditional tariffs, but of subsidies, quotas and regulations of all kinds. Even more likely, regional blocks will emerge that trade freely internally but are highly protectionist externally. The European Union, NAFFA and Mercosur already point in that direction.

The future of the corporation

Statistically, multinational companies play much the same part in the world economy as they did in 1913. But they have become very different animals. Multinationals in 1913 were domestic firms with subsidiaries abroad, each of them self-contained, in charge of a politically defined territory, and highly autonomous. Multinationals now tend to be organized globally along product or service lines. But like the multinationals of 1913, they are held together and controlled by ownership. By contrast, the multinationals of 2025 are likely to be held together and controlled by strategy. There will still be ownership, of course. But alliances, joint ventures, minority stakes, know-how agreements contracts will increasingly be the building blocks of a confederation. This kind of organization will need a new kind of top management.

In most countries, and even in a good many large and complex companies, top management is still seen as an extension of operating management. Tomorrow's top management, however, is likely to be a distinct and separate organ: it will stand for the company. One of the most important jobs ahead for the top management of {he big company of tomorrow, and especially of the multinational, will be to balance the conflicting demands on business being made by the need for both short-term and long-term results, and by the corporation's various constituencies: customers, shareholders, knowledge employees and communities.

1. The new society will be much more important than the new economy only in the developed countries.

2. In another 25 years people will have to keep working as full-time employees until their mid- 70s if health permits.

3. Nowadays in China, because of the population policy, the birth rate has decreased.

4. In developed countries, the issue of immigration will become important politically.

5. The dominant part in the next society's work force is

6. ______ makes knowledge spread rapidly and available to everyone.

7. ______ had dominated society for 10,000 years but declined rapidly in the 20th century.

8. In order to adjust for inflation, the cost of ______ which are the main knowledge products was tripled.

9. Multinationals in 1913 were composed of a domestic firms and its self-contained and autonomous

10. Top management in the Next society will be a ______ organ.

Passage2:

Rain forests

Tropical rainforests are the most diverse ecosystem (生态系统) on Earth, and also the oldest. Today, tropical rainforests cover only 6 percent of the Earth's ground surface, but they are home to

over half of the planet’s plant and animal species.

What Is a Rainforest?

Generally speaking, a rainforest is an environment that receives high rainfall and is dominated by tall trees. A wide range of ecosystems fall into this category, of course. But most of the time when people talk about rainforests, they mean the tropical rainforests located near the equator.

These forests receive between 160 and 400 inches of rain per year. The total annual rainfall is spread pretty evenly throughout the year, and the temperature rarely dips below 60 degrees Fahrenheit.

This steady climate is due to the position of rainforests on the globe. Because of the orientation of the Earth's axis, the Northern and Southern hemispheres each spend part of the year tilted away from the sun. Since rainforests are at the middle of the globe, located near the equator, they arc not especially affected by this change. They receive nearly the same amount of sunlight, and therefore heat, all year. Consequently, the weather in these regions remains fairly constant.

The consistently wet, warm weather and ample sunlight give plant life everything it needs to thrive. Trees have the resources to grow to tremendous heights, and they live for hundreds, even thousands, of years. These giants, which reach 60 to 150 ft in the air, form the basic structure of the rainforest. Their top branches spread wide in order to capture maximum sunlight. This creates a thick canopy (树冠) level at the top of the forest, with thinner greenery levels underneath. Some large trees grow so tall that they even tower over the canopy layer.

As you go lower, down into the rainforest, you find less and less greenery. The forest floor is made up of moss, fungi, and decaying plant matter that has fallen from the upper layers. The reason for this decrease in greenery is very simple the overabundance of plants gathering sunlight at the top of the forest blocks most sunlight from reaching the bottom of the forest, making it difficult for robust plants to thrive.

The, Forest for the Trees

The ample sunlight and extremely wet climate of many tropical areas encourage the growth of towering trees with wide canopies. This thick top layer of the rainforest dictates the lives of all other plants in the forest. New tree seedlings rarely survive to make it to the top unless some older trees die, creating a "hole" in the canopy. When this happens, all of the seedlings on the ground level compete intensely to reach the sunlight.

Many plant species reach the top of the forest by climbing the tall trees. It is much easier to ascend this way, because the plant doesn't have to form its own supporting structure.

Some plant species, called epiphytes, grow directly on the surface of the giant trees. These plants, which include a variety of orchids and ferns, make up much of the understory, the layer of the rainforest right below the canopy. Epiphytes are close enough to the top to receive adequate light, and the runoff from the canopy layer provides all the water and nutrients(养分)they need, which is important since they don't have access to the nutrients in the ground.

Stranglers and Buttresses

Some epiphytes eventually develop into stranglers. They grow long, thick roots that extend down the tree trunk into the ground. As they continue to grow, the roots form a sort of web structure all around the tree. At the same time, the strangler plant's branches extend upward, spreading out into the canopy. Eventually, the strangler may block so much light from above, and absorb such a high percentage of nutrients from the ground below, that the host tree dies.

Competition over nutrients is almost as intense as competition for light. The excessive rainfall rapidly dissolves nutrients in the soil making it relatively infertile except at the top layers. For this reason, rainforest tree roots grow outward to cover a wider area, rather than downward to lower levels. This makes rainforest trees somewhat unstable, since they don't have very strong anchors in the ground. Some trees compensate for this by growing natural buttresses. These buttresses are basically tree trunks that extend out from the side of the tree and clown to the ground, giving the tree additional support.

Rainforest trees are dependent on bacteria that are continually producing nutrients in the ground. Rainforest bacteria and trees have a very close, symbiotic (共生的) relationship. The trees provide the bacteria with food, in the form of fallen leaves and other material, and the bacteria break this material down into the nutrients that the trees need to survive.

One of the most remarkable things about rainforest plant life is its diversity. The temperate rainforests of the Pacific Northwest are mainly composed of a dozen or so tree species. A tropical rainforest, on the other hand, might have 300 distinct tree species.

All Creatures, Great and Small

Rainforests are home to the majority of animal species in the world. And a great number of species who now live in other environments, including humans, originally inhabited the rainforests. Researchers estimate that in a large rainforest area, there may be more than 10 million different animal species.

Most of these species have adapted for life in the upper levels of the rainforest, where food is most plentiful. Insects, which can easily climb or fly from tree to tree, make up the largest group (ants are the most abundant animal in the rainforest). Insect species have a highly symbiotic relationship with the plant life in a rainforest. The insects move from plant to plant, enjoying the wealth of food provided there. As they travel, the insects may pick up the plants' seeds, dropping them some distance away. This helps to disperse the population of the plant species over a larger area.

The numerous birds of the rainforest also play a major part in seed dispersal. When they eat fruit from a plant, the seeds pass through their digestive system. By the time they excrete (排泄) the seeds, the birds may have flown many miles away from the fruit-bearing tree.

There are also a large number of reptiles and mammals in the rainforest. Since the weather is so hot and humid during the day, most rainforest mammals are active only at night, dusk or dawn. The many rainforest bat species are especially well adapted for this lifestyle. Using their sonar, bats navigate easily through the mass of trees in the rainforest, feeding on insects and fruit.

While most rainforest species spend their lives in the trees, there is also a lot of life on the forest floor. Great apes, wild pigs, big cats and even elephants can all be found in rainforests. There are a number of people who live in the rainforests, as well. These tribes--which, up until recently, numbered in the thousands--are being forced out of the rainforests at an alarming rate because of deforestation.

Deforestation

In the past hundred years, humans have begun destroying rainforests at an alarming rate. Today, roughly 1.5 acres of rainforest are destroyed every second. People are cutting down the rainforests in pursuit of three major resources:

· land for crops

· lumber for paper and other wood products

· land for livestock pastures

In the current economy, people obviously have a need for all of these resources. But almost all experts agree that, over time, we will suffer much more from the destruction of the rainforests than we will benefit.

The world's rainforests are an extremely valuable natural resource, to be sure, but not for their lumber or their land. They are the main cradle of life on Earth, and they hold millions of unique life forms that we have yet to discover. Destroying the rainforests is comparable to destroying an unknown planet we have no idea what we're losing. If deforestation continues at its current rate, the world's tropical rainforests will be wiped out within 40 years.

1. Virtually all plant and animal species on Earth can be found in tropical rainforests.

2. There is not much change in the weather in the tropical rainforests all the year round.

3. The largest number of rainforests in the world are located on the African continent.

4. Below the canopy level of a tropical rainforest grows an overabundance of plants.

5. New tree seedlings will not survive to reach the canopy level unless ______.

6. Epiphytes, which form much of the understory of the rainforest, get all their water and nutrients from ______.

7. Stranglers are so called because they ______ by blocking the sunlight and competing for the nutrients.

8. Since rainforest bacteria and trees depend on each other for life, the relationship they form is termed ______.

9. Plant species are dispersed over a large area with the help of ______.

10. As we are still ignorant of millions of unique life forms in the rainforest, deforestation can be compared to the destruction of ______.

Passage3:

Some Notes on Gender-Neutral Language

General

The practice of assigning masculine gender to neutral terms comes from the fact that every language reflects the prejudices of the society in which it evolved, and English evolved through most of its history in a male-centered, patriarchal society. Like any other language, however, English is always changing. One only has to read aloud sentences from the 19th century hooks assigned for this class to sense the shifts that have occurred in the last 150 years. When readers pick up something to read, they expect different conventions depending on the time in which the material was written. As writers in 1995, we need to be not only aware of the conventions that our readers may expect, but also conscious of the responses our words may elicit. In addition, we need to know how the shifting nature of language can make certain words awkward or misleading. "Man"

Man once was a truly generic word referring to all humans, but has gradually narrowed in meaning to become a word that refers to adult male human beings. Anglo-Saxons used the word to refer to all people. One example of this occurs when an Anglo-Saxon writer refers to a seventh-century English princess as "a wonderful man". Man paralleled the Latin word homo, "a member of the human species." not vir, "an adult male of the species." The Old English word for adult male was waepman and the old English word for adult woman was wifman. In the course of time, wifman evolved into the word "woman." "Man" eventually ceased to be used to refer to

individual women and replaced waepman as a specific term distinguishing an adult male from an adult female. But man continued to be used in generalizations about both sexes.

By the 18th century, the modern, narrow sense of man was firmly established as the predominant one. When Edmund Burke, writing of the French Revolution, used men in the old, inclusive way, he took pains to spell out his meaning: "Such a deplorable havoc is made in the minds of men (both sexes) in France..." Thomas Jefferson did not make the same distinction in declaring that "all men are created equal" and "governments are instituted among men, deriving their just powers from the consent of the governed." In a time when women, having no vote, could neither give nor withhold consent, Jefferson had to be using the word men in its principal sense of "males," and it probably never occurred to him that anyone would think otherwise. Looking at modern dictionaries indicate that the definition that links "man' with males is the predominant one. Studies of college students and school children indicate that even when the broad definitions of "msn" and "men" are taught, they tend to conjure up images of male people only. We would never use the sentence "A girl grows up to be a man," because we assume the narrower definition of the word man.

The Pronoun Problem

The first grammars of modern English were written in the 16th and 17th centuries. They were mainly intended to help boys from upper class families prepare for the study of Latin, a language most scholars considered superior to English. The male authors of these earliest English grammars wrote for male readers in an age when few women were literate. The masculine-gender pronouns(代词) did not reflect a belief that masculine pronouns could refer to both sexes. The grammars of this period contain no indication that masculine pronouns were sex-inclusive when used in general references. Instead these pronouns reflected the reality of male cultural dominance and the male-centered world view that resulted.

"He" started to be used as a generic pronoun by grammarians who were trying to change a long-established tradition of using "they" as a singular pronoun. In 1850 an Act of Parliament gave official sanction(批准)to the recently invented concept of the "generic" he. In the language used in acts of Parliament, the new law said, "words importing the masculine gender shall be deemed and taken to include females." Although similar language in contracts and other legal documents subsequently helped reinforce this grammatical edict in all English-speaking countries, it was often conveniently ignored. In 1879, for example, a move to admit female physicians to the all-male Massachusetts Medical Society was effectively blocked on the grounds 'that the society's by-laws describing membership used the pronoun he.

Just as "man" is not truly generic in the 1990s, "he" is not a true generic pronoun. Studies have confirmed that most people understand "he" to refer to men only. Sentences like "A doctor is a busy person; he must be able to balance a million obligations at once" imply that all doctors are men. As a result of the fact that "he" is read by many as a masculine pronoun, many people, especially women, have come to feel that the generic pronouns excludes women. This means that more and more people find the use of such a pronoun problematic.

Solving the Pronoun Problem

They as a Singular -Most people, when writing and speaking informally, rely on singular they as a matter of course: "If you love someone, set them free" (Sting). If you pay attention to your own speech, you'll probably catch yourself using the same construction yourself. "It's enough to drive anyone out of their senses" (George Bernard Shaw). "I shouldn't like to punish anyone, even

ii they'd done me wrong" (George Eliot). Some people are annoyed by the incorrect grammar that this solution necessitates, but this construction is used more and more frequently.

He or She---Despite the charge of clumsiness, double-pronoun constructions have made a comeback: "To be black in this country is simply too pervasive an experience for any writer to omit from her or his work," wrote Samuel R. Delany. Overuse of this solution can be awkward, however.

Pluralizing-A writer can often recast material in the plural. For instance, instead of "As he advances in his program, the medical student has increasing opportunities for clinical work," try "As they advance in their program, medical students have increasing opportunities for clinical work"

Eliminating Pronouns--Avoid having to use pronouns at all; instead of "a first grader can feed and dress himself," you could write, "a first grader can eat find get dressed without assistance."

Further Alternatives--he she or s/he, using one instead of he, or using a new generic pronoun (thon, co, E, try, hash, hit).

1. "Man" could be used to refer to female human being in the past.

2. In "all men are created equal" in Declaration of Independence by Thomas Jefferson, the word "men" refer to both males and females whether they have vote right or not.

3. In 1879, Massachusetts Medical Society refused to admit more than ten female physicians because the society's by-laws describing membership used the pronoun he.

4. The first grammars of modern English were written in order to help boys from the upper class prepare for the study of Latin.

5. "Man" paralleled the Latin word "homo" 'which means ______.

6. Studies show that even when students are taught the broad definition of "man" and "men", they think of ______.

7. Grammarians started to use "he" as a generic pronoun because they were trying to change a tradition of using "they" as ______.

8. When most people read the word "he", they would understand it to rater to ______.

9. Although some people are annoyed by ______ of singular they, this construction is used more and more frequently to solve the pronoun problem.

10. Another way of solving the pronoun problem is to use ______ instead of the singular. Passage4:

Soichiro Honda

The founder of Honda, Soichiro Honda was a mechanical engineer with a passion for motorcycle and automobile racing. Honda started his company in 1946 by building motorized bicycles with small, war-surplus engines. Honda would grow to become the world's leading manufacturer of motorcycles and later one of the leading automakers. Following its founder's lead, Honda has always been a leader in technology, especially in the area of engine development.

Soichiro Honda was described as a maverick(特立独行的人) in a nation of conformists. He made it a point to wear loud suits and wildly colored shirts. An inventor by nature who often joined the work on the floors of his factories and research laboratories, Honda developed engines that transformed the motorcycle into a worldwide means of transportation.

Born in 1906, Honda grew up in the town of Tenryu, Japan. The eldest son of a blacksmith who repaired bicycles, the young Soichiro had only an elementary school education when, in his

teens, he left home to seek his fortune in Tokyo. An auto repair company hired him in 1922, but for a year he was forced to serve as a baby-sitter for the auto shop's owner and his wife. While employed at the auto shop, however, Honda built his own racing car using an old aircraft engine and handmade parts and participated in racing. His racing career was short lived, however. He suffered serious injuries in a 1936 crash.

By 1937, Honda had recovered from his injuries. He established his own company, manufacturing piston rings, but he found that he lacked a basic knowledge of casting. To obtain it, he enrolled in a technical high school, applying theories as he learned them in the classrooms to his own factory. But he did not bother to take examinations at the school. Informed that he would not be graduated, Honda commented that a diploma was "worth less than a movie theater ticket. A ticket guarantees that you can get into the theater. But a diploma doesn't guarantee that you can make a living."

Honda's burgeoning company mass produced metal propellers during WW Ⅱ, replacing wooden ones. Allied bombing and an earthquake destroyed most of his factory and he sold what was left to Toyota in 1945.

In 1946, he established the Honda Technical Research Institute to motorize bicycles with small, war-surplus engines. These bikes became very popular in Japan. The institute soon began making engines. Renamed Honda Motor in 1948, the company began manufacturing motorcycles. Business executive Takeo Fujisawa was hired to manage the company while Honda focused on engineering.

In 1951, Honda brought out the Dream Type E motorcycle, which proved an immediate success thanks to Honda's innovative overhead valve design, The smaller F-type cub (1952) accounted for 70% of Japan's motorcycle production by the end of that year. A public offering and support from Mitsubishi Bank allowed Honda to expand and begin exporting. The versatile C100 Super Cub, released in 1958, became an international bestseller.

In 1959, the American Honda Motor was founded and soon began using the slogan, "You meet the nicest people on a Honda," to offset the stereotype of motorcyclists during that period. Though the small bikes were dismissed by the dominant American and British manufacturers of the time, the inexpensive imports brought new riders into motorcycling and changed the industry forever in the United States.

Ever the racing enthusiast, Honda began entering his company's motorcycles in domestic Japanese races during the 1950s. In the mid-1950s, Honda declared that his company would someday win world championship events--a declaration that seemed unrealistic at the time.

In June 1959, the Honda racing team brought their first motorbike to compete in the Isle of Man Tourist Trophy race, then the world's most popular motorcycle race. This was the first entry by a Japanese team. With riders Naomi Taniguchi, who finished sixth, Teisuke Tanaka, who finished eighth, and Kiyoshi Kawashima, who would later succeed Soichiro as Honda Motor president, as team manager, Honda won the manufacturer's prize.

However, they were not pleased with their performance. Kawashima remembers: "We were clobbered. Our horsepower was less than half that of the winner."

Learning from this experience, Soichiro and his team worked even harder to make rapid progress in their motorsports activities. Two years after their first failure, they were the sensation at the TT by capturing the first five places in both the 125ce and 250cc classes. The upstart Japanese had outclassed all their rivals. As a result of the team's stellar performance, the Honda

name became well known worldwide, and its export volume rose dramatically. Soichiro seemed to have foreseen the future of Japan, which, twenty years later, was to become one of the world's leading economies.

Honda would become the most successful manufacturer in all of motorcycle racing. Honda has since won hundreds of national and world championships in all forms of motorcycle competition.

While Honda oversaw a worldwide company by the early-1970s (Honda entered the automobile market in 1967), he never shied away from getting his hands greasy. Sol Sanders, author of a Honda biography, said Honda appeared "almost daily" at the research lab where development work was being done. Even as president of the company, "he worked as one of the researchers,' Sanders quoted a Honda engineer as saying. "Whenever we encountered a problem, he studied it along with us."

In 1973, Honda, at 67, retired on the 25th anniversary of Honda's founding. He declared his conviction that Honda should remain a youthful company. "Honda has always moved ahead of the times, and I attribute its success to the fact that the firm possesses dreams and youthfulness," Honda said at the time.

Unlike most chief executive officers in Japan, who step down to become chairmen of their firms, Honda retained onty the title of "supreme adviser". In retirement, Honda devoted himself to public service and frequent travel abroad. He received the Order of the Sacred Treasure, first class, the highest honor bestowed by Japan's emperor. He also received the American auto industry's highest award when he was admitted to the Automotive Hall of Fame in 1989. Honda was awarded the AMA's highest honor, the Dud Perkins Award, in 1971.

Honda died on August 5, 1991 from liver failure at 84. His wife, Sachi, and three children survived him.

1. Soichiro Honda was a man who preferred to wear plain clothes.

2. When enrolled in a technical high school to obtain basic knowledge of casting, Soichiro Honda finally got the diploma after attending the examinations.

3. Like most chief executive officers in Japan, Soichiro Honda Stepped down to become chairmen of Honda after his retirement.

4. Even as the president of a worldwide company, Soichiro Honda would work at the research lab with the employees.

5. Following its founder's lead, Honda has always been a leader in technology, especially in the area of ______.

6. After WW Ⅱ, Honda mounted ______ on bicycles and these motorized bicycles sold rapidly in Japan.

7. A public offering and support from ______ allowed Honda to expand his business and begin to invade the international market.

8. In 1959, the American Honda Motor used the slogan," ______" to change the negative image of motorcyclists in America.

9. In 1959 with their first motorbike Honda racing team participate in ______ race, which was the most popular motorcycle race at that time.

10. According to Honda, ______ are, the major factors that led to the success of Honda company. Passage5:

A Brief History of Clock

Clocks

At best, historians know that 5,000-6,000 years ago, great civilizations in the Middle East and North Africa started to examine forms of clock-making instead of working with only the monthly and annual calendar. Little is known on exactly how these forms worked or indeed the actual deconstruction of the time, but it has been suggested that the intention was to maximize time available to achieve more as the size of the population grew. Perhaps such future periods of time were intended to benefit the community by allotting specific lengths of time to tasks. Was this the beginning of the working week?

Sun Clocks

With the disappearance of any ancient civilization, such as the Sumerian culture, knowledge is also lost. Whilst we can only hypothesize on the reasons of why the equivalent to the modern wristwatch was never completed, we know that the ancient Egyptians were next to layout a system of dividing the day into parts, similar to hours.

"Obelisks" (tall four-sided tapered monuments) were carefully constructed and even purposefully geographically located around 3500 BC. A shadow was east as the Sun moved across the sky by the obelisk, which it appears was then marked out in sections, allowing people to clearly see the two halves of the day. Some of the sections have also been found to indicate the "year"s longest and shortest days, which it is thought were developments added later to allow identification of other important time subdivisions.

Another ancient Egyptian "shadow clock" or "sundial" has been discovered to have been in use around 1500 BC, which allowed the measuring of the passage of "hours". The sections were divided into ten parts, With two "twilight hours" indicated, occurring in the morning and the evening. For it to work successfully then at midday or noon, the device had to be turned 180 degrees to measure the afternoon hours.

Water Clocks

"Water clocks" were among the earliest time keeping devices that didn't use the observation of the celestial bodies to calculate the passage of time. The ancient Greeks, it is believed, began using water clocks around 325 BC. Most of these clocks were used to determine the hours of the night, but may have also been used during daylight. An inherent problem with the water clock was that they were not totally accurate, as the system of measurement was based on the flow of water either into, or out of, a container which had markers around the sides. Another very similar form was that of a bowl that sank during a period as it was filled of water from a regulated flow. It is known that water clocks were common across the Middle East, and that these were still being used in North Africa during the early part of the twentieth-century.

Mechanical Clocks

In 1656, "Christian Huygens' (Dutch scientist), made the first "Pendulum(钟摆) clock", with a mechanism using a "natural" period of oscillation(振幅). "Galileo Galilei" is credited, in most historical books, for inventing the pendulum as early as 1582, but his design was not built before his death. Huygens' clock, when built, had an error of "less than only one minute a day". This was a massive leap in the development of maintaining accuracy, as this had previously never been achieved. Later refinements to the pendulum clock reduced this margin of error to "less than 10 seconds a day".

The mechanical clock continued to develop until they achieved an accuracy of "a

hundredth-of- a-second a day", when the pendulum clock became the accepted standard in most astronomical observatories.

Quartz Clocks

The running of a "Quartz clock" is based on the piezoelectric property of the quartz crystal. When an electric field is applied to a quartz crystal, it actually changes the shape of the crystal itself, If you then squeeze it or bend it, an electric field is generated. When placed in an appropriate electronic circuit, this interaction between the mechanical stress and the electrical field causes the crystal to vibrate, generating a constant electric signal which can then be used for example on an electronic clock display. The first wrist-watches that appeared in mass production used "LED", "Light Emitting Diode" displays. By the 1970's these were to be replaced by a "LCD", "Liquid Crystal Display".

Quartz clocks continue to dominate the market because of the accuracy and reliability of the performance, also being inexpensive to produce on mass scale. The time keeping performance of the quartz clock has now been surpassed by the "Atomic clock".

Atomic Clocks

Scientists discovered some time ago that atoms and molecules have "resonances" and that each chemical element and compound absorbs and emits "electromagnetic radiation" within its own characteristic "frequencies". This we are told is highly accurate even over "Time and Space".

The development of radar and the subsequent experimentation with high frequency radio communications during the 1930s and 1940s created a vast amount of knowledge regarding "electromagnetic waves", also known as "microwaves". which interact with the atoms. The development of atomic clocks focused firstly on microwave resonances in the chemical Ammonia and its molecules. In 1957. "NIST". the "National Institute of Standards and Technology", completed a series of tests using a "Cesium Atomic Beam" device, followed by a second program of experiments by NIST in order to have something for comparison when working at the atomic level. By 1960, as the outcome of the programs, "Cesium Time Standards" were incorporated as the official time keeping system at NIST.

The "Natural frequency" recognized currently is the measurement of time. used by all scientists, defines the period of "one second" as exactly "9,192,631,770 Oscillations" or "9,192,631,770 Cycles of the Cesium Atom's Resonant Frequency". From the "Macrocosm", or "Planetary Alignment", to the "Microcosm", or "Atomic Frequency", the cesium now maintains accuracy with a degree of error to about "one-millionth of a second per year".

Much of modern life has come to depend on such precise measurements of time. The day is long past when we could get by with a timepiece(钟)accurate to the nearest quarter hour. Transportation, financial markets, communication, manufacturing, electric power and many other technologies have become dependent on super-accurate clocks. Scientific research and the demands of modern technology continue re drive our search for ever more accuracy, The next generation of Cesium Time Standards is presently under development at NIST's "Boulder Laboratory" and other laboratories around the world.

Something to Remember

The only thing that should be remembered during all this technological development is that we should never lose the ability to tell the time approximately by natural means and the powers of deduction without requiring crutches(拐杖)to lean on.

Our concept of TIME and using it together with TECHNOLOGY still has room for radical

reassessment in terms of man's evolutionary thinking regarding our view of the past, our onward journey into the future and our concept of time in relationship to universe.

1. It is suggested that 5,000-6,000 years ago people in the Middle East and North Africa started to allot specific lengths of time to tasks.

2. Ancient Egyptian "shadow clock" or "sundial" discovered around 1500 BC, could measure passage of "hours" automatically and continuously.

It's Never Too Late to Start Exercise

Researchers Find Great Rewards When Mild Exercise Programs Are Started Late In Life.

May 13, 2003--You know the benefits of exercise programs. And if you've been inactive, you may have also felt them--with sore muscles and bruised motivation to continue. But a new study in women shows that the old adage is true--it's never too late to start when it comes to exercise programs. So now what can you do to jump on the exercise bandwagon (乐队花车)?

WebMD got exercise tips from the experts.

"There certainly seems to be something here to suggest that women can start exercising later in life and still reap the rewards," lead researcher and CDC epidemiologist Edward W. Gregg, PhD, tells WebMD. His findings are published in the May 16 issue of The Journal of the American Medical Association.

Researchers tracked 9,500 women for 12 years, starting when they were at least age 66. In that time, they found that those who went from doing little or nothing to walking just a mile a day slashed(减少) their risk Of death from all causes and from cancer by nearly half. Their risk of heart disease also fell by more than a third. In fact, they enjoyed nearly as much protection as women who were physically active before the study began and remained so.

During the study, he and his colleagues surveyed the women on their exercise levels at the start of the trial and again up to six years later. Years later, the researchers tracked their rates of death and disease.

The new information we found is that older women who went from being sedentary(少活动的) or walking about two miles a week to "walking eight miles a week between the two visits had significant life improvements," says another study researcher, Jane A. Cauley, DrPH, of the University of Pittsburgh.

"We're talking about women with an average age of 77 at the second visit," she tells WebMD.

"And we're talking about their engaging in very mild exercise--and not running marathons."

But if the only workout(运动)you've been getting lately involves the TV remote, here's how to avoid those walks around the block from making your body feel as if it just tackled Boston Marathon's infamous "Heartbreak Hill".

Get a checkup before a workout.

A visit to your doctor is wise for anyone beginning an exercise program, but it's crucial for the elderly or others who have been inactive because of health problems. In addition to the obvious-- checking your heart and lungs--your doctor can help determine if your regimen(养生法) needs to consider other medical conditions, and the drugs you take for them.

"People can sometimes control conditions such as diabetes and high blood pressure with weight loss and exercise so they don't need to continue their medications," says William A. Banks, MD, professor of geriatrics at Saint Louis University School of Medicine. It's important to let your doctor know about your new exercise program in case your medication doses need to be changed.

"A doctor can also help facilitate the best type of exercise if you have a disability or impairment. For instance, many of my patients have bad knees, so I tell them that if they start running or even walking, they're going tohave problems that will likely impact their ability to continue," he tells WebMD. "So I try to steer them to another activity, such as swimmings which is especially good for people with joint problems or obesity(肥胖)."

Start slow.

Once you get the green light, the key to avoiding fatigue and muscle pain is to pull out of the gate very slowly. "You hear so much about the importance of getting 30 minutes of exercise a day, but those recommendations should not be viewed as goals if you've been sedentary--even if you're healthy," Banks says. "Initially, you should actually shoot below your comfort level.

"Too often, people-especially those who are older overdo it in the beginning and hurt themselves to the point where they need two weeks to recover. It's better to walk for a few minutes a days every day, than do 10 minutes your first day and then not be able to walk for the rest of the week."

Go more often.

Of course, those few minutes of your exercise program can be done several times a day. First, try to do some activity for a few minutes several times a day. Then slowly increase the time spent in each session. But don't worry about going faster until you've exercised regularly for at least one month. A key to intensity= Ideally, you want to be aerobic(需要氧气的)enough so you can utter a few words or syllables in each sentence, but not so little that you're speaking in complete sentences or too much so you can barely talk, advises Banks.

Don't go solo.

Although there is no evidence that people are fitter when they exercise with others, they are more likely to stick to an exercise program, or anything else, with the buddy system. "We're always better in the company of others," says Banks.

Another benefit to group activities: Organized exercise programs, like those available for low or no cost at the YMCA or local hospitals, often include professional guidance--especially useful [or those with conditions such as obesity, diabetes, and arthritis. "There are exercise therapists or physiologists who can expertly guide you to the proper way to increase your endurance and intensity without risking injury or fatigue," says Gregg.

Do what you enjoy.

While Gregg's study and others have focused on walking because it's among the easiest and most popular forms of exercise, you should pick an activity you like, so you continue it. ]t could be gardening, swimming, tennis, or the old favorite, walking. "If you absolutely hate exercise, like me, I recommend exercise machines," says Banks. "Since I hate to exercise, I run on a treadmill(踏车) while watching TV. I'm especially fond of working out while watching the cartoon Pinky and the Brain."

1. It is suggested that women should not do exercises if they are over sixty.

2. According to Edward W. Gregg, it's never too late for women to start exercise.

3. All the 9,500 women who participated in the research would have little exercises or would only walk just a mile a day before the research.

4. Another benefit of group activities is that professional guidance in the group can help cure obesity, diabetes, and arthritis.

5. Since exercises may control conditions such as diabetes and high blood pressure, some old people don't need to ______ if they begin an exercise program.

6. As is suggested by William A. Banks, ______ is especially good for people with joint problems or obesity.

7. For those who just start to exercise, the best way to avoid fatigue and muscle pain is to ______.

8. For the exerciser, a simple method in checking the intensity of the exercise is to see that whether one can ______ while having the exercise.

9. In organized exercise programs, exercise therapists or physiologists can expertly guide an exerciser to the proper way to increase his or her ______ without risking injury or fatigue.

10. It is recommended that the exerciser should pick up an activity he/she likes so that he/she may ______.

Passage7:

Preparing for Weight Loss Surgery

For those who consider weight loss surgery, they are at the end of their ropes. Traditional methods of diet and exercise have had no effect, and this procedure is a last resort. But by no means is the leap from thinking about weight loss surgery to the operating table a short one.

"People need to be aware, in great detail, of the risk and benefits of weight loss surgery so they understand what it is all about," says Harvey J. Sugerman, president of the American Society for Bariatric Surgery. "The procedure is not without risk, and there is a great deal of anxiety that comes with it, so it takes considerable preparation."

From checking on insurance coverage to psychological exams to support groups, preparing for this life-changing procedure takes time, physical and mental readiness, and most of all, commitment.

First Steps

"From the time a person first thinks about having weight loss surgery, to the time they make the commitment to have it done is typically about two years," says James Kolenich, a bariatric surgeon at the University of Pennsylvania Medical Center, Horizon. "Most people don't rush into this, they talk to family and friends, they talk to the hospital, they go home and they think about it more; it's usually a very thoughtful approach."

More than 60 million obese people are living in the U. S. , according to the American Obesity Association (AOA), and about 9 million are severely obese. Weight loss surgery, also called

bariatric surgery, can be successful when diet and exercise have failed, and a person's health is on the line. Overweight is the second leading cause of preventable death, after smoking, in the U. S. , according to the AOA.

"The first thing a person should do is contact his insurance company to learn if he is covered for the surgery, and he should contact his primary care doctor to find out if there is documentation of his struggle with obesity," says Kolenich. "Many insurance companies want to know that a primary care doctor has tried to help the patient lose weight with psychological counseling, diet, and an exercise plan for five years, and for many patients, this is a big road block."

While there are other options, such as personally financing the procedure, they are costly: The National Institute of Diabetes and Digestive and Kidney Diseases web site states that this procedure can run from $ 20,000 to $ 35,000.

With such a hefty price tag on weight loss surgery, it pays to ensure that your doctor documents your battle with obesity early on, to open up options down the road. When you've crossed all your is and dotted all your is in the insurance category, it is time to find a hospital or center, and a surgeon, which are first-rate.

Finding a Batiatric Surgeon

"When you're looking for a surgeon, ask if he or she is board-certified by the American Board of Surgery," says Kotenich. "Is he a member of the American Society of Bariatrie Surgeons? What is the mortality rate of the surgeon, the morbidity rate, the success rate?"

Clearly, the surgeon you find should be well experienced in the area of weight loss surgery.

"Make sure the surgeon you choose is an experienced and qualified bariatrie surgeon," says Daniel Herren, chief of bariatric surgery at Mt. Sinai Hospital in New York. "It's clear that the more experienced the surgeon, the lower the risk of mortality. Ideally, you would prefer to find a surgeon who has performed at least 100 of these procedures."

What you are looking for doesn't stop with numbers and statistics--you will also need a support system, Look for a center or hospital that offers educational seminars to those who are just beginning the process so you can learn more about the actual procedure, the benefits, and the risks. Also look for support groups, that can be utilized pre- and post-operatively.

Preparing for Weight Loss Surgery

"The single most important factor is that they have to realize the surgery is not a cure for obesity," says Herren. "It's a very powerful tool used in the fight against obesity. It needs to be considered as part of a process, and a lifelong commitment to follow up with physicians, a regular exercise program, and healthy eating. If a person doesn't understand that this is a lifelong commitment, that it's net a quick fix, then he or she is not a good candidate."

From a physical standpoint, the preparation for weight loss surgery involves meeting with doctors--a lot of them.

A person also needs to meet with a nutritionist, to begin to better understand the elements of healthy eating, and how eating habits need to change before and after the surgery. "By getting into a proper nutritional mindset before surgery, such as learning to eat smaller portions, eating Slowly, paying closer attention to the nutritional make-up of meals, a person is better adapted for the major changes in their lifestyle after the surgery," says Herron.

Understanding the Risks

Understanding the possible outcomes of weight loss surgery, including the risks, is an important part of preparing for the procedure. "Education is a tremendously important part of the

preoperative process," says Herron. "There is no question that there are major risks associated with the operation. However, those risks can be minimized by having a thorough preoperative workup so there aren't surprises during the procedure, and by making sure the surgeon is experienced and qualified."

Nonetheless, dealing with the emotional toll of this procedure can be difficult, especially when considering the possibility of death. "There have been good studies looking at the risk of dying after weight loss surgery, showing that although there is a risk of death with surgery, the overall survival rate is improved with surgery compared to not having the surgery at all, and living with obesity," says Herron.

It helps that most centers and hospitals and insurance companies, require psychological evaluations prior to the allowing the procedure--which benefits both patient and doctor. "You have to fill your mind with as much optimism and positive thinking as possible," says Joe De Simone, PhD, a psychiatrist in private practice in N. Y., who works with patients preparing for weight loss surgery. "Basically, the preparation is to become more conscious of what you are thinking and feeling, and start preparing yourself to think of food and your life in a different way. This is a courageous step for people to take, and it's not just about weight changing--it's about life changing."

Pest-Op Expectations

While weight loss surgery does have a major impact on a person's life, it requires, like any surgical procedure, some recovery time. "The recovery period is quite variable," says Herron. "I have some patients who take a week off and are back full time, and others who take three to four weeks to recover. While it's certainly physically possible to be back to 90% of capacity after a week, most people take longer to adjust to the new lifestyle."

New techniques have also helped to lessen recovery time. Today, the procedure can be performed minimally invasively via small incisions. In a few centers around the country it can even be done on an outpatient basis.

Patients also need to remember weight loss surgery is not a cure. "It's not a magic bullet, but is an amazingly powerful weight-loss tool," says Herron. "A person will find they will lose about a pound per day for the first month or so. Then they'll lose between 50%-75% of their excess body weight typically during the first 12 months after surgery." What follows is dedication to a healthy diet and exercise regimen, continual follow-up with doctors to monitor progress, and commitment to a new life.

1. Weight loss surgery is one of the traditional ways of losing weight.

2. Many people have weight loss surgery possibly because overweight may give rise to death.

3. After having the weight loss surgery, a person will not suffer from obesity any more.

4. A person also might be required to quit smoking to improve the outcome of the operation.

5. It is advisable that a patient have his/her operation covered by the insurance company because weight loss surgery is usually ______.

6. A person who thinks about having weight loss surgery should find ______ bariatric surgeon.

7. Eating smaller portions, eating slowly, paying attention to the nutritional ______ of meals are examples of healthy eating habits.

8. During the preparing procedure, one important part is to help the candidates understand the possible outcomes and ______.

9. According to Herron, after having the surgery, the recovery time ______ from person to person.

10. With the development of ______, the recovery period may become shorter and shorter. Passage8:

Bird Brains

Cracking Walnuts

The scene: a traffic light crossing on a university campus in Japan. Carrion crows and humans line up patiently, waiting for the traffic to halt. When the lights change, the birds hop in front of the cars and place walnuts, which they picked from the adjoining trees, on the road. After the lights turn green again, the birds fly away and vehicles drive over the nuts, cracking them open. Finally, when it's time to cross again, the crows join the pedestrians and pick up their meal.

Biologists already knew the corvine family--it includes crows, ravens, rooks, magpies and jackdaws--to be among the smartest of all birds. But this remarkable piece of behavior would seem to be a particularly acute demonstration of bird intelligence. Researchers believe they probably noticed cars driving over nuts fallen from a walnut tree overhanging a road. The crows already knew about dropping clams from a height on the seashore to break them open, but found this did not work for walnuts because of their soft green outer shell.

Other birds do this, although not with quite the same precision. In the Dardia Mountains of Greece, eagles can be seen carrying tortoises up to a great height and dropping them on to rocks below.

Do Birds Have Intelligence?

Scientists have argued for decades over whether wild creatures, including birds, show genuine intelligence. Some still consider the human mind to be unique, with animals capable of only the simplest mental processes. But a new generation of scientists believes that creatures, including birds, can solve problems by insight and even learn by example, as human children do. Birds can even talk in a meaningful way.

Good Memory

Some birds show quite astonishing powers of recall. A type of North American crow may have the animal world's keenest memory. It collects up to 30,000 pine seeds over three weeks in November, and then carefully buries them for safe keeping across over an area of 200 square miles. Over the next eight months, it succeeds in retrieving over 90 percent of them, even when they are covered in feet of snow.

Making and Using Tools

On the Pacific island of New Caledonia, the crows demonstrate a tool-making, and tool using capability comparable to Paleolithic man's. Dr Gavin Hunt, a New Zealand biologist, spent three years observing the birds. He found that they used two different forms of hooked "tool" to pull grubs from deep within tree trunks. Other birds and some primates have been seen to use objects to forage. But what is unusual here is that the crows also make their own tools. Using their beaks as scissors and snippers, they fashion hooks from twigs, and make barbed, serrated rakes or combs from stiff leathery leaves. And they don't throw the tools away after one use--they carry them from one foraging place to another.

Scientists are still debating what this behavior means. Man's use of tools is considered a prime indication of his intelligence, is this a skill acquired by chance? Did the crows acquire tool making skills by trial and error rather than planning? Or, in its ability to adapt and exploit an enormous range of resources and habitats, is the crow closer to humans than any other creature?

Dr Hunt said this of his research: "There are many intriguing questions that remain to be answered about crows' tool behavior. Most important would be whether or not they mostly learn or genetically inherit the know-how to make and use tools. Without knowing that it is difficult to say anything about their intelligence, although one could guess that these crows have the capability to be as clever as crows in general."

The woodpecker finch is another consummate toolmaker; It will snap off a twig, trim it to size and use it to pry insects out of bark. In captivity, a cactus finch learnt how to do this by watching the woodpecker finch from its cage. The teacher helped the pupil by passing a ready- made spine across for the cactus finch to use.

Communication Ability

Another sign of intelligence, thought to be absent in most non-human animals, is the ability to engage in complex, meaningful communication. The work of Professor Irene Pepperberg of the University of Arizona, Tucson, has now shown the general perception of parrots as mindless mimics to be incorrect.

The captive African grey parrot Alex is one of a number of parrots now believed to have the intelligence and emotional make-up of a 3 to 4 year old child. Under the tutelage of Professor Pepperherg, he acquired a vocabulary of over 100 words. He could say the words for colors and shapes and, apparently, use them meaningfully. He has learned the labels for more than 35 different objects; he knows when to use "no," and phrases such as "come here," "I want X," and "Wanna go Y."

A bird's ability to understand, or speak, another bird's language can be very valuable. New Zealand saddlebacks occupy the same territory for years. They have distinct song "dialects" passed on through the generations. New territory vacancies are hard to find, so young males are always on the look-out for new widows into whose territory they can move. While they wander around the forest, they learn the different dialect songs, just as we might learn a language or develop a regional dialect. As soon as a territory-owning male dies, a new young male may move in to take over within 10 minutes. He will immediately start singing the dialect of the territory he is in.

Possessing Abstract Concepts

Intelligence--if this is what scientists agree these birds possess--is not limited to the birds we always thought of as "bright." In recent experiments at Cardiff University in Britain, a pigeon identified subtle differences between abstract designs that even art students did not notice. It could even tell that a Picasso was not the same as a Monet. The experiment seems to show that pigeons can hold concepts, or ideas, in their heads. The visual concept for the pigeon is Picasso's painting style.

Social Necessity Makes Birds Smart.

Scientists believe it is not physical need that drives creatures to become smarter, but social necessity. The complexities of living together require a higher level of intelligence. Corvids and parrots, along with dolphins, chimps, and humans are all highly social--and smart--animals.

Some ravens certainly apply their intelligence for the good of the flock. In North America, they contact other ravens to tell them the location of a carcass(动物尸体). Ravens are specialized feeders on the carcasses of large mammals such as moose during the harsh winter months of North America. The birds roost together at night on a tree, arriving noisily from all directions shortly before sunset. The next morning, all the birds leave the roost as highly synchronized(同步地)

groups at dawn, giving a few noisy caws, followed by honking. They may all be flying off in the direction taken by a bird, which had discovered a carcass the previous day. This bird leads the others to his food store, apparently sharing his finding with the rest of the flock.

Ravens share information about their findings of food carcasses because dead animals are patchily(散落地) distributed and hard to find. Many eyes have a better chance of finding a carcass, and once one has been located, the information is pooled(共享的). Although the carcass now has to be shared between more individuals, the heavy snowfall and risk of mammal scavengers (食腐动物) taking the food mean that a single bird or a small group could not eat it all alone anyway. Intelligence Inheritance

The level of intelligence among birds may vary. But no living bird is truly stupid. Each generation of bird's that leaves the protection of its parents to become independent has the inborn genetic information that will help it to survive in the outside world and the skills that it has learned from its parents. They would never have met the challenge of evolution without some degree of native cunning. It's just that some have much more than others.

距离大学英语六级考试还有不足一个月的时间，笔者给临战的考生朋友们一些建议。希望能通过本文帮大家梳理一个头绪，在最后的备战中尽量做到有的放矢，弹无虚发。 一、快速阅读。 大学六级中的第一道阅读题目是快速阅读，很多考生朋友都向笔者反映：快速阅读怎么做啊？拿到题目是先看文章还是先看题目啊？怎么我总是做不完题啊？有什么方法可以提高阅读速度啊？等等等等……这几个问题相信也是大家最关心的，那接下来，笔者将从六级快速阅读的命题特征，做题步骤，解题方法几个角度来谈谈如何攻克快速阅读。 1.六级快速阅读的命题特征。 六级快速阅读的文章篇幅约为1200单词，通常是略多一些的，整个题目的给定时间为15分钟。文章之后是十道题目，这十题可以会出现两种组合：一种为4道是非判断题(也就是大家所熟悉的Y/N/NG题)加上6道句子填空题(也可称补全句子)；另一种为7道选择题加上3道句子填空题。 至于考试最终会以哪种形式出题，在考纲中是没有明确说明的，从改革之后的几次实考情况来看，06年12月六级开始使用新题型，到09年6月的六级考试中，第一种题目组合形式考了两次，分别是06年12月和07年6月；第二种题目组合形式考了之后的四次。大家可以从以上的信息中来分配自己对于每种题型的复习时间。 2.六级快速阅读的做题步骤。 由于整个快速阅读部分总体时间为15分钟，如果不进行合理的规划，这样的时间是绝对不够用的。很多考生朋友会问到底应该以一种什么样的顺序来做题？我们先来了解一下在考试大纲中的说法： “要求考生运用略读和查读的技能从篇章中获取信息。略读考核学生通过快速阅读获取文章主旨大意或中心思想的能力，阅读速度约为每分钟120词。查读考核学生利用各种提示，如数字、大字单词、段首或句首词等，快速查找特定信息的能力。” 从考纲中我们发现，这里有三个重点信息：略读、查读、速度为120词/分钟。从这三点上我们基本上可以确实整体的步骤了，那就是选定信息+回到文章查找信息+对比解题。而且我们应该是看一题，做一题。这就是所谓的略读、查读。其实这正是我们平时所使用的从题干中找关键词，回文章定位的办法。快速阅读其实就是考定位。 而另外一个信息，阅读速度问题，表面上看到这个120词/分钟，很考生都望而却步，这绝对是一个无法企及的速度，但笔者提醒大家看它前面的文字，这样读的目的是为了获取文章主旨大意，而不是精细分析，于是结合大家以往所掌握的英语阅读知识应该知道，在英语中主旨的位置往往是相对固定的，想要把握1200个单词的文章的主旨根本不需要全文阅读，只需要看几个位置就可以了，如标题、首段、小标题。所以说这里的阅读速度应该更确切的讲是平均速度。

1.Why Integrity Matters What Is Integrity? The key to integrity is consistency- not only setting high personal standards for oneself (honesty, responsibility, respect for others, fairness) but also living up to those standards each and every day. One who has integrity is bound by and follows moral and ethical (道德上的) standards even when making life's hard choices, choices which may be clouded by stress, pressure to succeed, or temptation. What happens if we lie, cheat, steal, or violate other ethical standards? We feel disappointed in ourselves and ashamed. But a lapse (缺失) of integrity also affects our relationships with others. Trust is essential in any important relationship, whether personal or professional. Who can trust someone who is dishonest or unfair? Thus integrity must be one of our most important goals. Risky Business We are each responsible for our own decisions, even if the decision, making process has been undermined by stress or peer pressure. The real test of character is whether we can learn from our mistake, by understanding why we acted as we did and then exploring ways to avoid similar problems in the future. Making ethical decisions is a critical part of avoiding future problems. We must learn to recognize risks, because if we can't see the risks we're taking, we can't make responsible choices. To identify risks, we need to know the rules and be aware of the facts. For example, one who doesn't know the rules a about plagiarism (剽窃) may accidentally use words or ideas without giving proper credit or one who fails to keep careful research notes may unintentionally fail to quote and cite sources as required. But the fact that such a violation is "unintentional" does not excuse the misconduct, Ignorance is not a defense. "But Everybody Does It" Most people who get in trouble do know the rules and facts but manage to fool themselves about the risks they're taking by using excuses: "Everyone else does it." "I'm not hurting anyone", or "I really need this grade." Excuses can get very elaborate: "I know I'm look at another's exam, even though I'm supposed to keep my eyes on my own paper, but that's not cheating because I’m just checking my answers, not copying." We must be honest about our actions and avoid excuses, if we fool ourselves into believing we're not doing anything wrong, we can't see the real choice we're making - and that leads to bad decisions. To avoid fooling yourself, watch out for excuses and try this test: Ask how you would feel if your actions were public and anyone could be watching over yore shoulder. If you'd rather hide your actions, that's an indication that you're taking a risk and rationalizing it to yourself. Evaluating Risks To decide whether a risk is worth taking, you must examine the consequences, in the future as well as right now, negative as well as positive, and to others as well as to yourself. Those who take risks they later regret usually focus on immolate benefits and simply haven't considered what might go wrong. The consequences of getting caught are serious and may include a "O" on a test or assignment, an "F" in the class, suspension (暂令停学) or dismissal from school and a ruined reputation. In fact, when you break a role or law, you lose control over your life and give others the power to impose punishment that you have no control over. This is an extremely vulnerable (脆弱的) position. There may be some matters of life and death or highest principle, which might justify such a risk, but there aren't many things that fall in this category. Getting Away with it - Or Not Those who don't get caught pay an even higher price. A cheater doesn't learn from the test, which deprives (剥夺) him her of an education. Cheating undermines confidence and independence: the cheater is a fraud, and knows that without dishonesty, he/she would have failed. Cheating destroys self-respect and integrity, leaving the cheater ashamed, guilty and afraid of getting caught. Worst of all, a cheater who doesn't get caught the first time usually cheats again, not only because he/she is farther behind, but also because it seems "easier." This slippery slope of eroding ethics and bigger risks leads only to disaster. Eventually, the cheater gets caught, and the later he/she gets caught, the worse the consequences. Cheating Hurts Other, Too Cheaters often feel invisible, as if their actions "don't count" and don't really hurt anyone. But individual choices have an intense cumulative (累积的) effect. Cheating can spread like a disease. Recent statistics suggest 30％or more of college students cheat. If a class is graded on a curve, cheating hurts others' grades. Even if there is no curve, cheating "poisons" the classroom, and others may feel pressured to join in. ("If I don't cheat I can't compete with those who do") Cheating also has a destructive impact on teachers. The real reward of goof teaching is seeing students learn. But a cheater says. "I'm not interested in what you're trying to teach, all I care about is stealing a grade, regardless of the effect on others." The end result is a destructive attack on the quality of your education. Finally, cheating can hurt the reputation of the university and harm those who worked hard for their degree.

Section C Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A. , B. , C. and D.. Y ou should decide on the best choice and mark the corresponding letter on Answer sheet with a single line through the centre. Passage One Questions 46 to 50 are based on the following passage. Interactive television advertising, which allows viewers to use their remote controls to click on advertisements, has been pushed for years. Nearly a decade ago it was predicted that viewers of "Friends", a popular situation comedy, would soon be able to purchase a sweater like Jennifer Aniston's with a few taps on their remote control. "It's been the year of interactive television advertising for the last ten or twelve years," says Colin Dixon of a digital-media consultancy. So the news that Cablevision, an American cable company, was rolling out interactive advertisements to all its customers on October 6th was greeted with some skepticism. During commercials, an overlay will appear at the bottom of the screen, prompting viewers to press a button to request a free sample or order a catalogue. Cablevision hopes to allow customers to buy things with their remote controls early next year. Television advertising could do with a boost. Spending fell by 10% in the first half of the year. The popularization of digital video recorders has caused advertisers to worry that their commercials will be skipped. Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight. With the launch of interactive advertising, "many of the dollars that went to the Internet will come back to the TV," says David Kline of Cablevision. Or so the industry hopes. In theory, interactive advertising can engage viewers in a way that 30-second spots do not Unilever recently ran an interactive campaign for its Axe deodorant (除臭剂）, which kept viewers engaged for more than three minutes on average. The amount spent on interactive advertising on television is still small. Magna, an advertising agency, reckons it will be worth about $138 million this year. That falls far short of the billions of dollars people once expected it to generate. But DirecTV, Comcast and Time Warner Cable have all invested in it. A new effort led by Canoe V entures, a coalition of leading cable providers, aims to make interactive advertising available across America later this year. BrightLine iTV, which designs and sells interactive ads, says interest has surged: it expects its revenues almost to triple this year. BSkyB, Britain's biggest satellite-television service, already provides 9 million customers with interactive ads. Y et there are doubts whether people watching television, a "lean back" medium, crave interaction. Click-through rates have been high so far (around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty. Interactive ads and viewers might not go well together. 46. What does Colin Dixon mean by saying "It's been the year of interactive television advertising for the last ten or twelve years(Lines 4-5, Para. 1)? A. Interactive television advertising will become popular in 10-12 years. B. Interactive television advertising has been under debate for the last decade or so. C. Interactive television advertising is successful when incorporated into situation comedies.
