第一篇Captain Cook Arrow Legend(库克船

长弓箭的传说)

It was a great legend while it lasted, but DNA testing has finally ended a two-century-old story of the Hawaiian arrow carved from the bone of British explorer Captain James Cook who died in the Sandwich Islands in 1779.

―There is no Cook in the Australian Museum,‖ museum collection manager Jude Philip said not long ago in announcing the DNA evidence that the arrow was not made of Cook’s bone. But that will not stop the museum from continuing to display the arrow in its exhibition, ―Uncovered: Treasures of the Australian Museum,‖ which does include a feather cape presented to Cook by Hawaiian King Kalani’opu’u in 1778.

Cook was one of Britain’s great explorers and is credited with discovering the ―Great So uth Land,‖now Australia, in 1770. He was clubbed to death in the Sandwich Islands, now Hawaii.

The legend of Cook’s arrow began in 1824 when Hawaiian King Kamehameha on his deathbed gave the arrow to William Adams, a London surgeon and relative of Cook’s wife, saying it was made of Cook’s bone after the fatal fight with islanders.

In the 1890s the arrow was given to the Australian Museum and the legend continued until it came face-to-face with science.

DNA testing by laboratories in Australia and New Zealand revealed the arrow was not made of Cook’s bone but was more likely made of animal bone, said Philp.

However, Cook’s fans refuse to give up hope that one Cook legend will prove true and that part of his remains will still be uncovered, as they say there is evidence not all of Cook’s body was buried at sea in 1779. ―On this occasion technology has won,‖ said Cliff Thornton, president of the Captain Cook Society, in a statement from Britain. ―But I am sure that one of these days …one of the Cook legends will prove to be true and it will happen one day.‖

二Avalanche and Its Safety(雪崩和安全问

题)

An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are among the biggest dangers in the mountains for both life and property.

All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope that supports it. Determining the critical load, the amount of over-burden which is likely to cause an avalanche, is a complex task involving the evaluation of a numberof factors.

Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low risk of avalanche. Snow does not gather

significantly on steep slopes; also, snow does not flow easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow’s angle of rest is between 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is : A slope that is flat enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally, avalanche risk increases with use; that is , the more a slope is disturbed by skiers, thd more likely it is that an avalanche will occur.

Due to the complexity of the subject, winter travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous process, including route selection and examination of the snowpack, weather conditions, and human factors. Several well-known good habits can also reduce the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid attention to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are missing or damaged. Avoid traveling below others who might trigger an avalanche.

三Giant Structures(巨型建筑)

It is an impossible task to select the most amazing wonders of the modern world since every year more wonderful constructions appear.Here are three giant structures which are worthy of our admiration although they may have been surpassed by some more recent wonders.

The Petronas Twin Tower The petronas Towers were the tallest buildings in the world when they were completed in 1999.With a height of 452 metres;the tall twin owers,like two thin pencils,dominate the city of Kuala Lumpur.At the 41 flool,the towers are linked by a bridge,symbolizing a gateway to the city.The American architect Cesar Pelli designed the skyscrapers.

Constructed of high-strength concrete,the building provides around 1800 square metres of office space on every floor.And it has a shopping centre and a concert hall at the base.Other features of this impressive building include double-deckder lifts, and glass and steel sunshades.

The Millau Bridge

The Millau Bridge was opened in 2004 in the Tarn Valley, in southern France. At the time it was bui lt, it was the world’s highest bridge, reaching over 340m at the highest point. The bridge is described as one of the most amazingly beautiful bridge in the world. It was built to relieve Millau’s congestion problems. The congestion was then caused by

traffic passing from Paris to Barcelona in Spain. The bridge was built to withstand the most extreme seismic and climatic conditions. Besides, it is guaranteed for 120 years!

The Itaipu Dam

The Itaipu hydroelectric power plant is one of the largest constructions of its kind in the world. It consists of a series of dams across the River Parana, which forms a natural border between Brazil and Paraguay. Started in 1975 and taking 16 years to complete, the construction was carried out as a joint project between the two countries. The dam is well-known for both its electricity output and its size. In 1995 it produced 78% of Paraguay’s and 25% of Brazil’s energy needs. In its construction, the amount of iron and steel used was equivalent to over 300 Eiffel Towers. It is a truly amazing wonder of engineering.

四Animal’s “Sixth Sense”(动物的”第六感”)

A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a ―sixth sense‖ for disasters, experts said.

Sri Lankan wildlife officials have said the giant waves that killed over 24000 people along the Indian Ocean island’s coast clearly missed wild beasts, with no dead animals found.

―No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening,‖ H.D. Ratnayake, deputy director of Sri Lanka’s Wildli fe Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka’s biggest wildlife reserve and home to hundreds of wild elephants and several leopards.

―There has been a lot of apparent evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven,‖ said Matthew van lierop, an animal behavior specialist at Johannesburg Zoo.

―There have been no specific studies because you can’t really test it in a lab or field setting,‖ he told Reuters. Other authorities concurred with this assessment.

―Wildlife seem to be able to pick up certain phenomenon, especially birds… there are many reports of birds detecting impending disasters,‖ said Clive Walker, who has written several books on African wildlife.

Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators.

The notion of an animal ―sixth sense‖ – or

some other mythical power –is an enduring one which the evidence on Sri Lanka’s ravaged coast is likely to add to.

The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.

五Singing Alarms Could Save the Blind(警

报器救盲人)

If you cannot see, you may not be able to find your way out of a burning building – and that could be fatal. A company in Leeds could change all that with directional sound alarms capalbe of guiding you to the exit.

Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home for blind people in Sommerset and a resource centre for the blind in Cumbria. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from.

Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. ―It is a burst of white noise that people say sounds like static on the radio,‖ she says. ―Its life-saving potential is great.‖

She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the door without a sound alarm, but only 15 seconds with one.

Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms based on the same concept have already been installed on emergency vehicles.

The alarms will also include rising or falling frequencies to indicate whether people should go up or down stairs. They were developed with the aid of a large grant from British Nuclear Fuels.

六Car Thieves Could Be Stopped

Remotely(远程制止偷车贼)

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer, and a radio signal from a control center miles away will ensure that once the thief switches the engine off, he will not be able to start it again.

For now, such devices are only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and should be available to ordinary cars in the UK in two months.

The idea goes like this. A control box fitted to the car incorporates a miniature cellphone, a microprocessor and memory, and a GPS

satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the unit to block the vehicle’s engine management system and prevent the engine being restarted.

There are even plans for immobilizers that shut down vehicles on the move, though there are fears over the safety implications of such a system.

In the UK, an array of technical fixes is already making life harder for car thieves. ―The pattern of vehicles crime has changed,‖ says Martyn Rand all of Thatcham, a security research organization based in Berkshire that is funded in part by the motor insurance industry.

He says it would only take him a few minutes to teach a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.

Modern cars are a far tougher proposition, as their engine management computer will not allow them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this have helped achieve a 31 per cent drop in vehicle-related crime since 1997.

But determined criminals are still managing to find other ways to steal cars. Often by getting hold of the owner’s keys in a burglary. In 2000, 12 per cent of vehicles stolen in the UK were taken by using the owner’s keys, which doubles the previous year’s figure.

Remote-controlled immobilization system would put a major new obstacle in the criminal’s way by making such thefts pointless.

A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the customer expects.

七An Intelligent Car(智能汽车)

Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all these and can control a fast-moving car. But how does an intelligent car control itself?

There is a virtual driver in the smart car. This virtual driver has ―eyes‖, ―brains‖, ―hands‖ and ―feet‖, too. The minicameras on each side of the car are his ―eyes‖, which observe the road conditions ahead of it. They watch the traffic to the car’s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver’s―brain‖. His ―brain‖ calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right path for the intelligent car, and gives instructions to the ―hands‖and ―feet‖ to act accordingly. In this way, the virtual driver controls his car.

What is the virtual driver’s best advantage? He reacts quickly. The minicameras are

sending images continuously to the ―brain.‖ It completes the processing of the images within 100 milliseconds. However, the world’s best driver at least needs one second to react. Besides, when he takes action, he needs one more second.

The virtual driver is really wonderful. He can reduce the accident rate considerably on expressways. In this case, can we let him have the wheel at any time and in amy place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited . He can now only drive an intelligent car on expressways.

八Why India Needs Its Dying Vultures(印度为什么需要濒临灭亡的秃鹰)

The vultures in question may look ugly and threatening, but the sudden sharp decline in three species of India’s vultures is producing alarm rather than celebration. and it presents the world with a new kind of environmental problem. The dramatic decline in vulture numbers is causing widespread disruption to people living in the Same areas as the birds. It is also causing serious public health problems across the Indian sub-continent．

While4their reputation and appearance may be unpleasant to many Indians. vultures have long played a very important role in keeping towns and villages all over India clean. It is because they feed on dead cows. In India. cows are sacred animals and are traditionally left in the open when they die in their thousands upon thousands every year.

The disappearance of the vultures has led to an explosion in the numbers of wild dogs feeding on the remains of these dead animals. There are fears that rabies may increase as a result．And this terrifying disease may ultimately affect humans in the region, since wild dogs are its main carriers．Rabies could also spread to other animal species, causing an even greater problem in the future．

The need for action is urgent, so an emergency project has been launched to find a solution to this serious vulture problem. Scientists are trying to identify the disease causing the birds deaths and, if possible, develop a cure.

Large-scale vulture deaths were first noticed at the end of the 1980s in India. A population survey at that time showed that the three species of vultures had. Declined by over 90 percent. All three species are now listed as―critically endangered‖. As most vulture lay only single eggs and take about five years to reach maturity, reversing their population decline will be a long and difficult exercise.

九Wonder Webs(奇妙的网)

Spider webs are more than homes, and they are ingenious traps. And the world’s best web spinner may be the Golden Orb Weaver spider. The female Orb Weaver spins a web of fibers thin enough to be invisible to insect prey,

yet tough enough to snare a flying bird without breaking.

The secret of the web’s strength? A type of super-resilient silk called dragline. When the female spider is ready to weave the web’s spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly. Dragline is not sticky, so the spider can race back and forth along it to spin the web’s trademark spiral.

Unlike some spiders that weave a new web every day, a Golden Orb Weaver reuses her handiwork until it falls apart, sometimes not for two years. The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than Kevlar, a high-strength human-made material used in bullet-proof vests. And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original length and snap back as well as new. No human-made fiber even comes close.

It is no wonder manufacturers are clamoring for spider silk. In the consumer pipeline: high-performance fabrics for athletes and stockings that never run. Think parachute cords and suspension bridge cables. A steady supply of spider silk would be worth billions of dollars – but how to produce it? Harvesting silk on spider farms does not work because the territorial arthropods have a tendency to devour their neighbors.

Now, scientists at the biotechnology company Nexia are spinning artificial silk modeled after Golden Orb dragline. The first step: extract silk-making genes from the spiders. Next, implant the genes into goat egg cells. The nanny goats that grow from the eggs secrete dragline silk proteins in their milk. ―T he young goats pass on the silk-making gene without any help from us,‖ says Nexia president Jeffrey Turner. Nexia is still perfecting the spinning process, but they hope artificial spider silk will soon be snagging customers as fast as the real thing snags bugs. Chicken Soup for the Soul:Comfort Food Fights Lneliness（心灵鸡汤：爽心食品排解

孤独感）

Mashed potatoes, macaroni and cheese, may be bad for your arteries，but according to a study in Psychological Science, they’re good for your heart and emotions．The study fo cuses on ―comfort food‖ and how it makes people feel．

"For me personally,food has always played a big role in my family,‖ says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study．The study came out of the research program of his co—author Shira Gabriel．It has looked at non-human things that may affect human emotions．Some people reduce loneliness by

bonding with their favorite TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones．Troisi and Gabriel wondered if comfort food could have the same effect by making people think of their nearest and dearest.

In one experiment, in order to make participants feel lonely, the researchers had them write for six minutes about a fight with someone close to them．Others were given an emotionally neutral writing assignment. Then, some people in each group wrote about the experience of eating a comfort food and others wrote about eating a new food．Finally,the researchers had participants complete questions about their levels of loneliness．Writing about a fight with a close person made people feel lonely．But people who were generally secure in their relationships would feel less lonely by writing about a comfort food．"We have found that comfort foods are consistently associated with those close to us．"says Troisi．"Thinking about or consuming these foods later then serves as a reminder of those close others．"In their essays on comfort food, many people wrote about the experience of eating food with family and friends.

In another experiment, eating chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food．This was a question they had been asked long before the experiment, along with many other questions, so they wouldn’t remember it.

Throughout everyone’s daily lives they experience stress, often associated with our connections with others," Troisi says．"Comfort food Can be an easy remedy for loneliness．

Climate Change Poses Major Risks for Unprepared Cities （气候变化给不备城市

带来重大风险）

A new examination of urban policies has been carried out recently by Patricia Romero Lankao．She is a sociologist specializing in climate change and urban development．She war ns that many of the world’s fast-growing urban areas，especially in developing countries．will likely suffer from the impacts of changing climate．Her work also concludes that most cities are failing to reduce emissions of carbon dioxide and other greenhouse gases．These gases are known to affect the atmosphere．‖Climate change is a deeply local issue and poses profound threats to the growing cities of the world,‖ says Romero Lankao. ‖But too few cities are developing effective strategies to protect their residents."

Cities are major sources of greenhouse gases．And urban populations are likely to be among those most severely affected by future climate change. Lankao’s findings highlight ways in which

city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term benefits．

The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat heavily paved cities more than surrounding areas．The impacts of such natural events can be more serious in an urban environment．For example，a prolonged heat wave can increase existing levels of air pollution，causing widespread health problems．Poorer neighborhoods that may lack basic facilities such as drinking water or a dependable network of roads，are especially vulnerable to natural disasters．Many residents in poorer countries live in substandard housing without access to reliable drinking water，roads and basic services.

Local governments, therefore,should take measures to protect their residents.‖Unfortunately，they tend to move towards rhetoric rather than meaningful responses, Romero Lankao writes, ‖ They don’t impose construction standards that could reduce heating and air conditioning needs. They don't emphasize mass transit and reduce automobile use. In fact, many local governments are taking a hands—off approach.‖ Thus, she urges them to change their idle policies and to take strong steps to prevent the harmful effects of climate change on cities..

Free Statins With Fast Food Could Neutralize Heart Risk (快餐加免费降胆固醇药物可以降低罹患心脏病的风险)

Fast food outlets could provide statin drugs free of charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London suggest in a new study．

Statins reduce the amount of unhealth y ‖LDL‖ cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person’s heart attack risk .

In a paper published in the American Journal of Cardiology，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is enough to offset the increase in heart attack risk from eating a cheeseburger and drinking a milkshake．

Dr Francis，from the National Heart and Lung Institute at Imperial College London，who is the senior author of the study, said:‖Statins don’t cut out a11 of the unhealthy effects of cheeseburgers and French fries．It’s better to avoid fatty food altogether．But we’ve worked out that in terms of your possibility of having a heart attack.

Taking a statin can reduce your risk to more or less the same degree as a fast food meal increases it.‖ ―It’s ironic that people are free to take as many unhealthv condiments in fast food outlets as they like, but statins, which are beneficial to heart health, have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are provided free of charge．It would cost less than 5 pence per customer一not much different to a sachet of sugar.‖ Dr Francis said．

When people engage in risky behaviours like driving or smoking, they’re encouraged to take measures that lower their risk, 1ike wearing a seatbelt or choosing cigarettes with filters. Taking a statin is a rational way of lowering some of the risks of eating a fatty meal．

Better Solar Energy Systems: More Heat, More Light （更有效的太阳能系统：更多热量，更强灯光）

Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’t a very efficient way to gather heat.

That’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it’s also a space problem: photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications.

In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen’s University, Canada.

Most solar panels are made with crystalline silicon, but you can also make solar cells out of amorphous silicon, commonly known as thin-film silicon. They don’t create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon, they have a greener footprint. Unfortunately, thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.

―That means that their efficiency drops when you expose them to light—pretty much the worst possible effect for a solar cell,‖ Pearce explains, which is one of the reasons thin-film solar panels make up only a small fraction of the market.

However, Pearce and his team found a way to engineer around the Staebler-Wronski

effect by incorporating thin-film silicon in a new type of PVT. You don’t h ave to cool down thin-film silicon to make it work. In fact, Pearce’s group discovered that by heating it to solar-thermal operating temperatures, near the boiling point of water, they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the cell once a day, they boosted the solar cell’s electrical efficiency by over 10 percent.

Sharks Perform a Service for Earth's Waters（鲨鱼有益于地球水系）

It is hard to get people to think of sharks as anything but a deadly enemy1. They are thought to attack people frequently. But these fish2 perform a valuable service for earth's waters and for human beings. Yet business and sport fishing3 are threatening their existence Some sharks are at risk of disappearing from Earth

Warm weather may influence both fish and shark activity. Many fish swim near coastal areas because of their warm waters. Experts say sharks may follow the fish into the same areas, where people also swim. In fact, most sharks do not purposely charge at or bite humans. They are thought to mistake a person for a sea animal, such as a seal or sea lion. That is why people should not swim in the ocean when the sun goes down or comes up. Those are the times when sharks are looking for food. Experts also say that bright colors and shiny jewelry may cause sharks to attack.

A shark has an extremely good sense of smell4' It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks fred their food. Sharks eat fish, any other sharks, and plants that live in the ocean.

Medical researchers want to learn more about the shark's body defense, and immune systems against disease. Researchers know that sharks recover quickly from injuries. They study the shark in hopes of finding a way to fight human disease.

Sharks are important for the world's oceans They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too great This protects the plants and other forms of life that exist in the oceans. “Liquefaction” Key to Much of Japanese Earthquake Damage （“液化”是日本地震破

坏的关键）

The massive subduction zone1 earthquake in Japan caused a significant level of soil "liquefaction" that has surprised researchers with its widespread severity, a new analysis shows.

"We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and extent of damage in Japan were unusually severe," said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University5. "Entire structures were tilted and sinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities need to function. We saw some places that sank as much as four feet."

Some degree of soil liquefaction7 is common in almost any major earthquake. It's a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their strength and flow during an earthquake. This can allow structures to shift or sink or collapse .

But most earthquakes are much shorter than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this.

"With such a long-lasting earthquake, we saw how structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on recently filled ground, are much more vulnerable."

The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil phenomenon and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, before damage was removed in the recovery efforts.

"There's no doubt that we'll learn things from what happened in Japan10 that11 will help us to reduce risks in other similar events ," Ashford said. "Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns."

Ashford pointed out that northern California have younger soils vulnerable to liquefaction ---on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic terms, may be those deposited within the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.

Anything near a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to prevent

collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction standards helped prevent many buildings from collapse ---even as they tilted and sank into the ground.

职称英语考试完形填空解题技巧 1. 三一定律：如果选项当中有三个词同义、意思相近、或者是褒贬色彩一样。那么这种情况下，与这三个选项有区别的那一项99%是正确选项。 2. 如果选项当中有两个选项的词的词形结构有类似的地方，它的不同往往就会带上一些语法标志（如动词的时态、名词的单复数等）。这两个选项当中一定有一个是正确选项，在回到文章当中去比对，就很容易找出正确答案了。那么我们可以排除掉其它两个选项。 3. 如果选项中有两个词同义且有细微的区别，答案必在其中，取范围广者。 4. 如果选项中有两个选项互为反义，答案在其中，回原文找线索。 5. 两个并列动词之间的关系：①中间加to；②后面动词加ing；③加动词原形，前动词是使役动词。 6. 横线后面出现了than，则横线上多半考的就是形容词或副词的比较等级。 7. 选项中某个词在文章的前面或是后面出现过，那么此词很有可能是正确答案。 8. 剩余的实词题就需要根据原文的内容来确定:如果横线前后提到了选项当中提到了选项当中的某个词，那么横线就

极有可能是这个选项。 9. 词义辨析，直接通过四个选项词的意思 9. 介词题考的是固定搭配，其前的动词或名词、其后的名词就显得尤其的重要。要求考生一定要背一些固定搭配的短语。 10. 连接代词和连接副词题，考的就是从句的引导词(尤其是以定语从句为主)：①如果横线前是介词，则选项应选which；②如果选项中有“介词+which”这个选项，则该选项多半是正确答案；③非限定性定语从句中，先行词是人，用who，先行词是物，用which，先行词是句子，用which； ④三种用that的情况。 接下来，我们就以实际的一篇例题来让大家体会一下，到底我们所讲的这个解题技巧在完形填空的解题当中起到了多大的作用： Think as a Hacker Does At the brand-new Hacker Academy in Chicago, US, students learn about phishing schemes, firewall breaches, and advanced tricks for breaking into confidential documents and revealing passwords.

2014年职称英语 完形填空(4) Animal's Sixth Sense

第四篇 Animal?s “Sixth Sense” A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, 1 , seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that 1 they possess a “sixth sense” for 2 , experts said.

2021年职称英语查词典的技巧

职称英语查词典的技巧 职称英语是闭卷考，但允许考生携带词典进入考场。关于词典，国家有明确的规定，以下词典不允许带入考场： 有职称字样的词典不要带入考场; 针对职称英语考试编写的词典不能带入考场; 电子出版物，即电子词典不能带入考场。 其它的词典国家没有明确的规定。因此建议尽量选择具备同义词、收词量相对较大的词典。 此外，能否取胜职称英语，掌握查词典的技巧，尤其是合理分配查词典的时间也是很关键的。 在以往的`考试中，很多考生把词典当成“救命稻草”，抱着一大堆各种类型的词典进考场。但往往不是多数词典派不上用场，就是因为翻词典而浪费了大量的时间无法做完 ___，因此，建议:要有针对性地带词典。例如针对英语考试中的第一部分词汇题，老师建议考生带一本同义词词典或双解词典，这类词典的特点是用几个同义词注解某一英文单词，考生可以非常方便地在注解中找到答案。

其次，为了节省时间，考生最好是带自己经常使用、习惯了其编排规律的词典。在以往的考试中，甚至有少数考生对英语词典中字母表排列顺序的规律都不了解，这等于把这一得力工具浪费了。 综上所述，带一本自己常用的，正规的双解词典就好了，因为是去参加考试，不是去翻字典。 对于词汇选择题，最好从B、C两个选项查起。根据美国权威机构通过对标准化考试的研究与分析，选择题的4个选项中，B、C两个选项是正确答案的可能性更高。从这2个选项查起，更能节约考试时间。 重点查阅单词的常用解释。单词与汉语一样，一个单词可能同时有好几个解释，但是职称英语考试中一般都只会考察单词的常用意思，因此有多个解释的单词只需查阅其前三个解释即可。 一旦将答案确定，不要再查询其它单词，以免浪费时间。有些考生希望能确认或是不太肯定所选择答案，往往就把4个选项均查询了一遍，不仅浪费了时间，也可能将原本的正确答案修改了，第一感觉是很重要的!

职称英语考试完形填空拿高分的技巧

职称英语考试完形填空拿高分的技巧2017年职称英语考试完形填空拿高分的技巧 (1)语法和词汇 (2)固定搭配 (3)上下文的逻辑推理 在最后的冲刺阶段，首要任务是将职称英语教材中的新增文章再次复习一遍，加强对文章的记忆和理解。 其次，职称英语考生需要参考历年完型考试的真题，熟悉题型特点，考生可以从历年真题中总结并学习职称英语考试中一些不断重复的语法考点，比如动词时态，冠词考察，介词等的考查。 最后，职称英语考生一定要记住，良好的学习心态、积极的应试心理也是考试制胜的关键因素。在职称英语考场上要保持镇定，从容应答，这样才能唤醒记忆，将所学所掌握的知识应用到职称英语考试中。 完型填空必做三项功课 一、主要考察内容：完形填空旨在测试考生对语言的理解程度和综合运用语言的`能力。职称英语考试中的完形填空测试是一篇难度适中，长度为150词左右的短文。短文中留出15个空白，每个空白为一题，每题有四个选项。要求考生在全面理解内容的基础上选择最佳答案，使短文意思完整、文理通顺、结构严谨、主题明确。 完形填空考题的设计一般是从以下三个方面出发的：(1)语法结构(2)词法结构(3)上下文之间的逻辑关系。

在15个选项中，要求填入实词(动词、名词和形容词等)的约占70%，其他为虚词(介词、副词等)的约占30%.要填的词几乎涉及各 个词类，动词含有不同的时态和语态。 二、复习策略分析 1.复习方向：完形填空的复习主要以本类别和本级别的完型填空的文章为主，尤其是以本类别和级别新增文章为重点进行复习，然 后再去看本类别的非新增文章，如有精力以其他类别的完型填空的 文章作为练习训练去做做。 2.一般的解题步骤： 通读全文 首先要阅读整篇文章，理解全文内容。同时对全文的语言表达方式，比如文章用的时态、语态、文章的措辞与口气等方面得出大致 印象。 逻辑判断 在阅读全篇的基础上，开始从头判断每个空所缺的词的语言形式，如词类、时态、语态;并判断该词应具有的符合文章上下文的词义。 理解选择 从给出的4个选项中，选出在语法与词义上均与原文相符合的一个。 三、高分通关必做的三项功课： 1.语法知识的积累职称英语考试完型填空题型能否顺利拿下分数，除了对重点文章的正掌握外，平时对语法知识的积累是非常重要的。很大程度上完形填空都在考查考生运用语法知识的能力，因此在强 化阶段，考生应该对职称考试中涉及的语法点进行巩固复习。 2.固定搭配与词组的记忆完型填空中大部分都是考查的动词等的固定搭配、常用的词组等，因此考生在强化阶段应该注意对平时阅 读中出现的固定搭配与词组进行搜集、积累与记忆。

https://www.wendangku.net/doc/e69965856.html,/ .375. School Lunch Research has shown that over half the children in Britain who take their own lunches to school do not eat properly in the middle of the day.In Britain schools have to provide meals at lunchtime.Children can choose to bring their own food or have lunch at the school canteen. One shocking finding of this research is that school meals are much healthier than lunches prepared by parents.There are strict standards for the preparation of school meals,which have to include one portion of fruit and one of vegetables,as well as meat,a dairy item and starchy food like bread or pasta.Lunchboxes examined by researchers contained sweet drinks,crisps and chocolate bars.Children consume twice as much sugar as they should at lunch time. The research will provide a better understanding of why the percentage of overweight students in Britain has increased in the last decade.Unfortunately,the government cannot criticise parents,but it can remind them of the nutritional value of milk,fruit and vegetables.Small changes in their children’s diet can_affect their future health.Children can easily develop bad eating_habits at this age,and parents are the only ones who can prevent it.A Powerful Influence There can be no doubt at all that the Internet has made a huge difference1to our lives.Parents are worried that children spend too much time playing on the Internet,hardly ever doing anything else in their spare time.Naturally,parents are curious to find out why the Internet is so attractive,and they want to know if it can be harmful for their children.Should parents worry if their children are spending that much time staring at their computers? Obviously,if children are bent over their computers for hours,absorbed in some game,instead of doing their homework,then something is wrong.Parents and children could decide how much use the child should_make of the Internet,and the child should give his or her word that it won’t interfere with homework.If the child is not holding to this arrangement,the parent can take more drastic steps dealing with a child’s use of the Internet is not much different from negotiating any other sort of bargain about behaviour.Any parent who is_seriously alarmed about a child’s behaviour should make an appointment to discuss the matter with a teacher.Spending time in front of the screen does not necessarily affect a child’s performance at school.Even if a child is absolutely crazy about using the Internet,he or she is probably just going through a phase,and in a few months there will be something else to worry about!The Old Gate In the Middle Ages the vast majority of European cities had walls around them.This was partly for defensive reasons but another factor was the need to keep out anyone regarded as undesirable,like people with contagious diseases.The Old City of London gates were all demolished by the end of the 18th century.The last of London’s gates was removed a century ago,but by a stroke of luck,it was never destroyed. This gate is,in actual fact,not called a gate at all;its name is Temple Bar,and it marked the boundary between the Old City of London and Westminster.In 1878the Council of London took the Bar down,numbered the stones and put the gate in storage because its design was unfashionable it was expensive to maintain and it was blocking the traffic. The Temple Bar Trust was set up in the 1970’s with the intention of returning the gate home.The aim of the Trust is the preservation of the nation’s architectural heritage.Transporting the gate will mean physically pulling it down,stone by stone,removing and rebuilding it near St Paul’s Cathedral.Most of the facade of the gate will probably be replaced,though there is a good chance that the basic structure will be sound.The hardest job of all,however,will be to recreate the statues of the monarchs that once stood on top of the gate.Family History In an age when technology is developing faster than ever before,many people are being attracted to the idea of looking back into the past.One way they can do this is by investigating their own family history.They can try to find out more about where their families came from and what they did.This is now a fast-growing hobby,especially in countries with a fairly short history,like Australia and the United States. It is one thing to spend some time going through a book on family history and to take the decision to investigate your own family’s past.It is quite another to carry out the research work successfully.It is easy to set about it in a disorganized way and_cause yourself many problems which could have been avoided with a little forward planning. If your own family stories tell you that you are connected with a famous character,whether hero or criminal,do not let this idea take over your research.Just treat it as an interesting possibility.A simple system for collecting and storing your information will be adequate to start with;a more complex one may only get in your way.The most important thing,though,is to get started.Who knows what you might find? Helen and Martin With a thoughtful sigh,Helen turned away from the window and walked back to her favourite armchair.Would her brother never arrive?For a brief moment,she wondered if she really cared that much. Over the years Helen had given up waiting for Martin to take an interest in her.Her feelings for him had gradually weakened until now,as she sat waiting for him,she experienced no more than a sister’s curiosity to see what had become of her brother. Almost without warning,Martin had lost his job with a busy publishing company after spending the last eight years in New York as a key figure in the US office.Somehow the two of them hadn’t bothered to keep in touch and,left alone,Helen had slowly found
