Text 1

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

46 A good title for this passage is ____.

A. Sleep C. Dreams

B. Good Health D. Work and Rest

47. The word drowsy in the last paragraph means ____.

A. sick C. asleep

B. stand up D. a little sleepy

Obviously television has both advantages and disadvantages.

In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don’t have to

pay for expensive seats at the theatre, the cinema, or the opera .All they have to so is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if the has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort in his part.

Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it ,so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and the they have actually begin to talk to each other again. It makes one think, doesn’t it?

There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society.

51. What is the major function of paragraph 1?

A. To arouse the reader’s concern

B. To introduce the theme of the whole passage

C. To summarize the whole passage

D. To sate the primary uses of TV

52. Television, as a source of entertainment, is ______.

A. not very convenient

B. very expensive

C. quite dangerous

D. relatively cheap

53. Why are some people against TV?

A. Because TV programs re not interesting

B. Because TV viewers are totally passive

C. Because TV prices are very high.

D. Because TV has both advantages and disadvantages

54. One of the most obvious advantages of TV is that ______.

A. it keeps us informed

B. it is very cheap

C. it enables us to have a rest

D. it controls our lives

55. According to the passage, whether TV is good or not depends on _______ .

A. its quality

B. people ’s attitude towards it

C. how we use it

D. when we use it

Text 3

Too often young people get themselves employed quite by accident, not

knowing what lies in the way of opportunity for promotion, happiness and security. As a result, they are employed doing jobs that afford them little or no satisfaction. Our school leavers face so much competition that they seldom care what they do as long as they can earn a living . Some stay long at a job and learn to like it ;others quite from one to another looking for something to suit them, the young graduates who leave the university look for jobs that offer a salary up to their expectation. Very few go out into the world knowing exactly what they want and realizing their own abilities. The reason behind all this confusion is that there never has been a proper vocational guidance in our educational institution. Nearly all grope(摸索) in the dark and their chief concern when they look for a job is to ask what salary is like. They never bother to think whether they are suited for the job or, even more important, whether the job suits them, Having a job is more than merely providing yourself and your dependants with daily bread and some money for leisure and entertainment, It sets a pattern of life and, in many ways, determines social status in life, selection of friends, leisure and interest.

In choosing a career you should first consider the type of work which will suit your interest .Noting is more pathetic than taking on a job in which you have no interest, for it will not only discourage your desire to succeed in life but also ruin your talents and ultimately make you an emotional wreck (受到严重伤害的人)and a bitter person.

56. The reason why some people are unlikely to succeed in life is that they _____ .

A. have ruined their talents

B. have taken on an unsuitable job

C. think of nothing but their salary

D. are not aware of their own potential

57. The difficulty in choosing a suitable job lies mainly in that_____ .

A. much competition has to be faced

B. many employees have no working experience

C. the young people only care about how much they can earn

D. schools fail to offer students appropriate vocational guidance

58. Which of the following statements is most important according to the passage?

A. Your job must suit your interest.

B. Your job must set a pattern of life.

C. Your job must offer you a high salary.

D. Your job must not ruin your talents.

59.The best title for this passage would be ____.

A. What Can A Good Job Offer

B. Earning A Living

C. Correct Attitude On Job-hunting

D. How To Choose A Job

60. The word “pathetic”in paragraph 2 most probably means ____ .

A. splendid

B. miserable

C. disgusted

D. touching

Part B

Directions:

The 12,000 members of the Electricity Workers’Union on strike last week and since then there has been no electricity. For question 61-65, match the names with the statements below. Mark your answers on ANSWER SHEET 1.

Mr. Mike Smith:

It wasn’t an easy decision, but we’ve been asking for a decent wage for years. Now at last people are beginning to listen to us. We’re only asking for a 25 percent increase in our wages. 250 dollars a week. That’s all. It’s pity so many people have to be inconvenienced by out strike. But please don’t blame us. Blame the government for refusing our claim.

Mr. Tom Brown:

It’s totally unreasonable to demand so much money when we are trying desperately to control inflation. If wages go up, so do prices. If we gave in to the electricity workers, all the other unions would want more, with the inevitable result that the crisis would become uncontrollable. What we’re trying to impress upon everybody is that inflation hurts everybody, especially the poor people. We offer the electricity workers a 10 percent increase. And that’s already too much. My stand at this meeting will be to persuade the Union to see reason.

Mr. Bob Davis:

Everybody will be hurt by this strike, including the electricity workers themselves. The economy will be destroyed and many people will lose their jobs. Already people are saying that the big unions have too much power and shouldn’t be allowed to strike. O course the electricity want to get more money. Don’t we all?

Mr. Baker:

My opinion is “Get the Army in”. All the power stations should be managed by the army. The strikers should be thrown into prison. That’s what this country needs. Why must we all suffer just because a few men are greedy? If they don’t like their jobs, nobody ‘s forcing them to work. They should try and live on 50 dollars a week like I have to. Perhaps they’d keep their mouths shut then.

Miss Slater:

Let’s face it. It’s neither here nor there. The electricity workers are in a strong position. Perhaps we can’t do anything bout it. What I say is: let them have their 250 dollars so we can return to work. I mean, the government wastes the taxpayers’money all the time on trivial things. How can anyone say 250 dollars is “too much”? Pop singers get more. Nurses get less. It’s just one of those things.

Now match each of the persons (61 to 65) to the appropriate statement.

Note: there are two extra statements.

Statements

61. Mr. Mike Smith

62. Mr. Tom Brown

63.Mr. Bob David

64.Mrs. baker

65. Miss Slater

[A] A % increase is already too much, and I’m here to persuade the Union to see reason.

[B] I hope that strikes should be banned in all sectors relating to the nation’s security and stability.

[C] We will never go back to work until our goals are achieved.

[D] I think that the government should give in to the electricity worker’s demands.

[E] I strongly suggest that all the power stations should be run by the army and that the strikers should be put into prison.

[F] I must take you clear that strikes will destroy the economy and that many people will lose their jobs.

[G] We are forced to call a strike because the government rejected our wage claim.

Most young people enjoy physical activities, walking, cycling, football, or mountaineering.

These who have a passion 26 climbing high and difficult mountains are often 27 with astonishment. Why are men and women 28 to suffer cold and hardship, and to 29 on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activities 30 which men give their leisure.

There are no man-made rules, as there are for 31 as golf and football. There are, of course, rules of different kinds which it would be dangerous to 32 , but it is this freedom from man-made rules 33 makes mountaineering attractive to many people.

If we 35 mountaineering with other more familiar sports, we might think that one big difference is 36 mountaineering is not a “team work”. However, it is only our misunderstanding.

Text I

Fifteen years ago, I entered the Boston Globe, which was a temple to me then. It wasn’t easy getting hired. But once you were there, I found, you were in.

Globe jobs were for life-guaranteed until retirement. For 15 years I had prospered there —moving from an ordinary reporter to foreign correspondent and finally to senior editor. I would have a lifetime of security is I struck with it. Instead, I had mad e a decision to leave. I entered my boss’s office. Would he rage? I wondered. He had a famous temper. “Matt, we have to have a talk,” I began awkwardly. “I came to the Globe when I was twenty-four. Now I’m forty. There’s a lot I want to do in life. I’m resigning.” “To another paper?” he asked. I reached into my coat pocket, but didn’t say anything. I handed him a letter that explained everything. It said that I was leaving to start a new media company. We were at a rare turning point in history. I wanted to be directly engaged in the change. “I’m glad for you,” he said, quite out of my exp ectation. “I just came from a board of directors meeting and it was seventy-five percent discouraging news. Some of that we can deal with. But much of it we can’t, ” he went on. “I wish you all the luck in the world,” he concluded. “And if it doesn’t work out, remember, your star is always high here.”

Then I went out of his office, walking through the newsroom for more good-byes. Everybody was saying congratulations. Everybody —even though I’d be risking all on an unfamiliar venture: all the financial security I had carefully built up.

Later, I had a final talk with Bill Taylor, chairman and publisher of the Boston Globe. He had turned the Globe into a billion-dollar property. “I’m resigning, Bill, ”

I said. He listened while I gave him the story. He wasn’t looking angry or dismayed eit her. After a pause, he said, “Golly, I wish I were in your shoes.”

46. From the passage we know that the Globe is a famous _______.

[A] newspaper [B] magazine

[C]temple [ D ] church

[ A] he would be able to realize his lifetime dreams.

[ B] he would let his long-cherished dreams fade away.

[ C ] he would never have to worry about his future life.

[ D] he would never be allowed to develop his ambitions.

48. The writer wanted to resign because _________.

[A] he had serious trouble with his boss.

[ B ] he got underpaid at his job for the Globe.

[ C ] he wanted to be engaged in the new media industry.

[ D ] he had found a better paid job in a publishing house.

49. When the writer decided to resign the Globe was faced with _______.

[ A ] a trouble with its staff members

[ B ] a shortage of qualified reporters

[ C ] an unfavorable business situation

[ D ]an uncontrollable business situation

50. By “:I wish I were in your shoes.”(in the last paragraph) Bill Taylor meant that _______.

[ A ] the writer was to fail.

[ B] the writer was stupid

[ C ] he would do the same if possible

[D] he would reject the writer’s request

Text 2

Do you find it very difficult and painful to get up in the morning? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.

During the hours when your labor through your work you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as: “Get up, Peter! You’ll be late for work again!” The possible explanation to the trouble is that Peter is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.

You can’t change your energy cycle, but you can learn to make your life fit if better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway.

Text 3

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”—

conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature —a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would mane agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible) Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?

56. As pointed out at the beginning of the passage, people used to think that air pollution _______.

[ A ] cause widespread damage in the countryside

[ B ] affected the entire eastern half of the United States

[ C ] had damaged effect on health

[ D ] existed merely in urban and industries areas

57. As to the greenhouse effect, the author __________.

[ A ] share the same view with the scientist.

[ B ] is uncertain of its occurrence

[ C ] rejects it as being ungrounded

[ D ] thinks that it will destroy the world soon

58. The word “offset”in the second paragraph could be replaced by _________.

[ A] slip into [ B ] make up for

[ C ] set up [ D ] catch up with

59. It can be concluded that ____________.

[ A ] raising the world’s temperature only a few degrees would not do much harm to life on earth.

[ B] lowering the world’s temperature merely a few degrees would lead major farming areas to disaster.

[C] almost no temperature variations have occurred over the past decade.

[D] the world’s temperature will remain constant in the years to come.

60. This passage is primarily about __________.

[A]the greenhouse effect..

[ B ] the burning of fossil fuels..

[C] the potential effect of air pollution.

[ D] the likelihood of a new ice age.

Part B

Directions:

Read the following article in which five people talk about their ideas of dieting. For questions 61 to 65 , -match name of each speaker to one of the statements (A to C ) given below. Mark your answers on your ANSWER SHEET.

Abbey

You can always recognize dieters from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts, gazing at themselves in mirrors, and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. What a miserable lot dieters are!

Marlin

I began making some dietary and lifestyles changes during my second year of college and have been eating this way ever since. I like the way I feel when I don't eat animal foods so much more than the pleasure I used to get from eating them. I have much more energy; I need less sleep; I feel calmer; I can maintain an ideal body weight without worrying about how much I eat, and I can think more clearly.

Maggie

During my first year of college, I gained forty pounds when I began throwing the javelin. For the next twenty years, I carried all of this extra weight and kidded myself that I was in good shape since that's what I weighed in college. Now that I've lost all that extra weight, I feel great! People say all the time, "Well, how do you live without eating cheeseburgers or this or that?" and I say, "You just don't. It' s not even an option. It's not that hard once you get on it. "

Belinda

If you are on a diet, you're always hungry. You can't be hungry and happy at the same time. All the horrible concoctions you eat instead of food leave you permanently dissatisfied. A complete food it may be, but not quite as complete as juicy steak. So at least three times a day you will be exposed to temptation. How miserable to watch others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice! And if hunger just proves too much for you, in the end

you will lash out and devour five huge guilt-inducing cream cakes at a sitting. Then things will turn out to be even worse.

Wood

I went on diet when my doctor told me that my blood pressure tended to be high. Only at that time did I realize the danger of being overweight. Since I began making dietary changes in 1982, eating this way has become increasingly accepted. I don't feel I've lost something after dieting. Instead, I’ve got something va luable. That is good health.

Now match each of the persons to the appropriate statement.

Note: there are two extra statements.

Statements

61. Abbey [A] Being on a diet is a torture.

62. Marlin [ B] I feel better with vegetarian food.

63. Maggie [C] I lost weight after dieting.

[ D] I began dieting for the sake of health.

64. Belinda [E] Dieting enables people to enjoy life more.

65. Wood [F] Dieting simply causes endless worries.

[ G] Dieting does more harm than good to one' s health.

(完整版)《市场营销》模拟试题1参考答案

《市场营销》模拟试题1参考答案班级：姓名：学号：一、案例分析题一、美国钟表公司通过市场营销研究发现，可把市场上的购买者分为三类：第一类消费者希望能以尽量低的价格购买能计时的手表，他们追求的是低价位的实用品,这类消费者占23％。第二类消费者希望能以较高的价格购买计时准确、更耐用或式样好的手表，他们既重实用，又重美观，这类消费者占46％。第三类消费者想买名贵的手表，主要是把它作为礼物，他们占整个市场的31％。于是,根据第一、二类消费者的需要，避开日本精工和西铁城名表，制造了一种叫做“天美时”的物美价廉的手表，一年内保修，而且利用新的销售渠道，广泛通过商店、超级市场、廉价商店、药房等各种类型的商店大力推销，结果很快提高了市场占有率，成为世界上最大的钟表公司之一。单项选择：（每小题2分,共6分） 1．天美时公司采用什么样的市场细分标准将市场分为三种类型？（C ） A．地理环境细分B．心理细分C．购买行为细分D．人口因素细分2．天美时公司选择了哪种目标市场策略？（B） A．差异性营销策略B．集中性营销策略C．无差异营销策略 3．天美时公司采用的是哪一种市场定位策略？（ A ） A．避强定位B．迎头定位C．重新定位（8分）比了下去？试用市场营销环境理论分析之。答：（1）20世纪初期，汽车供不应求，竞争对手很少，福特公司凭借创建汽车生产流水线，以高效率、低成本赢得市场。20世纪20年代，汽车市场发生变化，竞争对手增多，汽车供应量增加，人们变得挑剔起来，不再是“企业生产什么，我就买什么了”。（2）任何企业的活动都离不开营销环境。福特公司后来比通用公司比了下去的根本原因是忽视市场营销环境的变化，尤其是忽视顾客需求的变化，一意孤行地认为“不管顾客需要什么，我的车就是黑色的”。还有就是忽视对竞争对手的分析。而通用公司则针对福特公司的营销策略及“挑剔的顾客”推出“汽车形式多样化”,最大限度地满足顾客的需求，从而在市场上远远超过了福特公司。三、有四家公司，其经营决策是：（8分） A公司生产手表，认为只要生产走时精确、造型优美、价格适中的名牌产品，即能获得经营成功。

钢结构模拟试题一(含答案)

钢结构模拟试题一一、简答题 1.简述钢结构有哪些主要特点。（8分）答：（1）材料的强度高，塑性和韧性好；（2）材质均匀，和力学计算的假定比较符合；（3）制作简便，施工周期短；（4）质量轻；（5）钢材耐腐蚀性差；（6）钢材耐热，但不耐火； 2.碳素结构钢按质量分为几级？并是怎样划分的？Q235B·b代表的意义是什么？（10分）答：碳素结构钢按质量分为A、B、C、D四级。其中A级钢材不作冲击韧性要求，冷弯性能在需方有要求时才进行；B、C、D各级钢材均要求冲击韧性值Akv≥27J，且冷弯试验均要求合格，所不同的是三者的试验温度有所不同，B级要求常温（20±5℃）冲击值，C和D级则分别要求0℃和-20℃冲击值。 Q235B·b代表屈服强度为 2 235N/mm，B级，半镇静钢。 3.钢结构中，选用钢材时要考虑哪些主要因素？（8分）答：结构或构件的重要性；荷载的性质(静载或动载)；连接方法（焊接、铆接或螺栓连接）；工作条件（温度及腐蚀介质）。 4.轴心受力构件的截面形式有哪几种？并且对轴心受力构件截面形式的共同要求是什么？答：轴心受力构件的截面形式有热轧型钢、冷弯薄壁型钢、实腹式组合截面以及格构式组合截面。对轴心受力构件截面形式的共同要求是：（1）能提供强度所需要的截面积；（2）制作比较简便；（3）便于和相邻的构件连接；（4）截面开展而壁厚较薄，以满足刚度要求。 5.计算压弯（拉弯）构件的强度时，根据不同情况，采用几种强度计算准则？并简述各准则的内容。我国钢结构规范对于一般构件采用哪一准则作为强度极限？（10分）答：计算压弯（拉弯）构件的强度时，根据不同情况，采用三种强度计算准则。其中（1）截面边缘纤维屈服准则：当构件受力最大截面边缘处的最大应力达到屈服时，即认为构件达到了强度极限。（2）全截面屈服准则：这一准则以构件最大受力截面形成塑性铰为强度极限。（3）部分发展塑性准则：这一准则以构件最大受力截面的部分受压区和受拉区进入塑性为强度极限。我国钢结构规范对于一般构件采用部分发展塑性准则作为强度极限。 6. 简述梁的整体失稳现象，影响梁临界弯距的主要因素有哪些。（8分）答：梁的截面一般窄而高，弯矩作用在其最大刚度平面内，当荷载较小时，梁的弯曲平衡状态是稳定的。当荷载增大到某一数值后，梁在弯矩作用平面内弯曲的同时，将突然发生侧向的弯曲和扭转变形，并丧失继续承载的能力，这种现象称为梁的整体失稳现象。梁的临界弯矩Mcr主要和梁的侧向抗弯刚度、抗扭刚度、翘曲刚度、梁的截面形状、荷载类型、荷载作用位置以及梁的跨度等有关。 7.钢结构框架钢柱的计算长度系数与哪些因素有关。（6分）答：钢结构框架钢柱的计算长度系数与框架类型、相交于柱上端节点的横梁线刚度之和与柱线刚度之和的比值K1、相交于柱下端节点的横梁线刚度之和与柱线刚度之和的比值K2、柱与基础的连接方式、横梁远端连接方式、横梁轴力大小以及柱的形式等因素有关。 8.简述焊接残余应力对结构性能的影响。（8分）答：（1）对结构静力强度的影响：不影响结构的静力强度；（2）对结构刚度的影响：残余应力使构件的变形增大，刚度降低；（3）对压杆稳定的影响：焊接残余应力使压杆的挠曲刚度减小，从而必定降低其稳定承载能力；
