Fear and its companion pain are two of the most useful things that man and animals possess if they are used. If fire didn’t hurt when it burned, children would play with it until their hands were burned away. Similarly, if pain existed but fear didn’t, a child could burn itself again and again because fear would not warn it to keep away from the fire that had burnt it before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which man and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. The important thing is not to let fear rule you, but instead, to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is well.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent an airplane crashing into your house, and you may not want to go and live in a desert where there are no airplanes. In this case, fear has given you its warning, you have examined it and decided on your course of action, so fear of the particular danger is no longer of any use to you, and you have to try to overcome it.
60. Children would play with fire until their hands are burnt away if _________.
A. they were not well educated at school   B. they had never played with fire before
C. they had no sense of pain             D. they were fearful of pain
61. People sometimes succeed in timely avoiding danger because _________.
A. they have gained experience     B. they are warned of the danger and take quick action
C. they jump out of the way in time  D. they are calm in face of danger
62. What is implied but not stated in the passage?
A. Too much fear is harmful              
B. Fear is always something helpful
C .Fear is something that can be avoided     
D. Fear ought to be used as our guide in our life
63.The best title for this passage should be __________.
A. No Pains, No Gains          B. Pain and Actions
C. The Value of Fear         D .The Reason Why People Fear

No one can fail to stand in awed ( 令人敬畏的 ) admiration of the great discoveries of history—Newton' s laws of motion; Kepler' s principles of planetary movement, Einstein' s general theory of relativity. Equally awe-inspiring are artistic creations in painting, theatre, music and literature, which have also been brought about by discovery through personal efforts.  What do these extraordinary achievements of well-known scientists and artists have to do with problem solving?
A great scientific discovery or a great work of art is surely the result of problem-solving activity. The solution to a problem, we are told, often comes to thinkers in a “flash of insight (頓悟) ”, although they may have been turning the problem over in their minds for some time. As a particular form of problem solving, these creative acts are based on the broad knowledge gained in the past, whether this be of the public" sort known to science, or of the "private" sort known to the artist.
Many creative thinkers state that they have completely devoted themselves to the subject matter of the problem, often over fairly long periods of time. Indeed, it would be strange if they had not done this. Nothing in such statements supports the idea that there is anything very different about the problem solving that leads to discoveries of the great contributions to the society. The act of discovery, even in the relatively predictable (可以預(yù)見的) sense that it occurs in everyday learning, involves (涉及) a “sudden insight” which changes the problem situation into a solution situation. As we have seen, everyday discovery also requires that the learner have the knowledge of the rules gained in the past, which is involved in the solution.
52. Newton, Kepler and Einstein are mentioned in the first paragraph to_______.
A. bring about the subject of the discussion        
B. explain that scientists are more creative
C. show the difference between science and arts
D. prove that arts require more personal efforts
53. While knowledge from the past plays an important role in their achievements, thinkers sometimes also depend on their______.
A. artistic tastes                    B. sudden insight
C. admiration of discoveries  D. scientific experiments
54. What does the underlined word “this” refer to?
A. Great contributions to the society            
B.  Long-time study of the subject matter.
C.  Various statements about problem solving.
D. Complete devotion to artistic creation.
55. We may conclude from the passage that ______.
A.it is more likely to make scientific and artistic discoveries in everyday learning.
B. a sudden insight and knowledge from the past are required in making discoveries
C. scientific discoveries or artistic creations are usually unpredictable in nature
D. knowledge of the rules in the past is often developed in the changes of situation

C
Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺槳)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋風(fēng)片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
63. According to the passage, which of the following statements is true?
A. The rotating blades can kill as many birds as high-rise buildings do
B. Single families are not encouraged to build turbines.
C. The USA produces more wind power than any other country in the world.
D. The noise the turbines make may discourage people from building them.
64. The underlined word “generator” in the third paragraph probably means_______.
A. 電動機                 B. 發(fā)電機                    C. 機翼                       D. 飛機引擎
65. If the USA wants to build wind turbines in an area with 30,000 homes, how many
should they build at least?
A. 50.                          B. 150.                         C. 250.                         D. 200.
66. All the following are the advantages of wind energy EXCEPT that_________.
A. it is environmentally friendly                        B. it is free to build and operate
C. the government supports it                                   D. the energy is clean and renewable

第三部分:閱讀理解(共20小題,每小題2分,滿分40分)
閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項。
A
A lot of management training each year for Circle K Corporation, a national chain of convenience stores. Among the topics we address in our course is the retention(保護(hù)力) of quality employees-a real challenge to managers when you consider the pay scale(標(biāo)準(zhǔn))in the service industry. During these discussions, I ask the participants(參加者), “What has caused you to stay long enough to become a manager?” Some time back a new manager took the question and slowly, with her voice almost breaking, said, “It was a $19 baseball glove.”
Cynthia told the group that she originally took a Circle K clerk job as an interim(臨時的) position while she looked for something better. On her second or third day behind the counter, she received a phone call from her nine-year-old son, Jessie. He needed a baseball glove for Little League. She explained that as a single mother, money was very tight, and her first check would have to go for paying bills. Perhaps she could buy his baseball glove with her second or third check. When Cynthia arrived for work the next morning, Patricia, the store manager, asked her to come to the small room in the back of the store that served as an office. Cynthia wondered if she had done something wrong or left some part of her job incomplete from the day before. She was concerned and confused.
Patricia handed her a box. “I overheard you talking to your son yesterday,” she said, “and I know that it is hard to explain things to kids. This is a baseball glove for Jessie because he may not understand how important he is, even though you have to pay bills before you can buy gloves. You know we can’t pay good people like you as much as we would like to; but we do care, and I want you to know you are important to us.”
The thoughtfulness, empathy and love of this convenience store manager demonstrates vividly that people remember more how much an employer cares than how much the employer pays. An important lesson for the price of a Little League baseball glove.
56.Among many of the problems in the service industry, what is talked about in this passage, is___
A.how to ensure his employees’ high pay
B.how to attract more customers
C.how to look carefully after the employees
D.how to keep the good employees from leaving
57.Although a new manager, Cynthia would do her job well in keeping quality employees because she________.
A.had mastered all the courses for the manager
B.had already formed good relationship with the employees
C.know the way how to deal with her employees
D.had her own personal experience
58.This passage shows us that to run a business well it is necessary for managers to let their employees know________
A.how much they can get for their job.
B.what good positions they can get later
C.they are very necessary to the business  
D.they are nice as well as useful
59.The story told in this passage tells us that employees care about____________   
A.only how large a pay they can get
B.love from the managing people rather than only money
C.if their children could be properly taken care of
D.what position they can be offered

B
Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution:less water, less hydropower and less wind energy.
Scientists studied the effects of aerosol(浮質(zhì))pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.
Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense(凝結(jié))onto a particle to form a raindrop. And if the cloud of fine droplets(小滴)moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.
Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate(微粒的)pollution over the oceans.
60. The first paragraph mainly talks about        .
A. the results of vehicle pollution
B. an introduction to particles from car exhausts
C. less wind energy in polluted regions
D. less water caused by vehicle pollution
61. From this passage we can learn that        .
A. scientists supported their idea by using material models
B. the new study is contrary to the previous findings
C. if there are more particles in the atmosphere, there will be more raindrops
D. there is a cause and effect relationship between wind speeds and particle pollution
62. The underlined word “induce” in Paragraph 3 most probably mean       _ .
A. reduce         B. persuade           C. cause             D. produce
63. What’s the best title for the passage?
A. Pollution and Global Warming          B. Car, Wind and Rain
C. Industry Pollution                    D. How Rain Forms

Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as “population pollution.”
About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.
59. The rapid increase in population is considered to be __________.
A. the increase of resources          B. population pollution
C. the development of mankind       D. the present rate
60. The world population will be _________ by the year 2,000.
A. 7 billion                  B. 250 million       C. 25 billion      D. 3.5 billion
61. If the present rate of increase continue, ________________.
A. the world is going to end
B. the earth won’t be able to support the growing population in the future
C. pollution has nothing to do with the rapidly increasing population
D. there would be four billion in the world a hundred years from now
62. Which of the following is WRONG according to the passage?
A. In 1850 the world population reached a billion.
B. Man must fight a battle against population pollution.
C. The world’s population is increasing with years.
D. All of the earth’s resources are gone now.
