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(螺桨)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(螺旋风片) 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

The United States will introduce a new and comprehensive(综合的) exam for students who seek to study in American and other English-speaking countries, Xinhua News Agency reported from New York.
The exam, which stands for a great change from the current English level test, was disclosed by Theresa Chang Wei Jen, associate director of the International Service of the US College Board, America’s leading educational organization.
The Advanced Placement International English Language (APIEL) will be offered for the first time throughout the world, said Jen.
However, the APIEL is a strange title to most Chinese students, and it is unlikely to soon gain the similarity of other already existing exams, such as the TOEFL(Test of English as a Foreign Language), the GRE(Graduate Record Examination), or the IELTS(International English Language Testing System).
“I have never heard of such a test and I would prefer the IELTS if I need another exam,” said Xu Jingyan, a graduating student from Beijing University of Aeronautics and Astronautics, who wants to study in England and has already taken the TOEFL.
Most of Xu’s classmates have never heard of the APIEL. “The APIEL is designed for international students who wish to get university studies in English-speaking countries, including the United States, Britain, Canada, and Australia.” said Jen.
The APIEL has been adopted, said Jen, because the TOEFL can no longer accurately reflect the abilities of students of using the English language comprehensively in an academic environment. Xinhua reported that a fairly large number of foreign students who earned high scores in TOEFL exam turned out to be very ordinary educational performers after admission.
Compared with the TOEFL, the APIEL measures a student’s ability to read, write, speak and understand English through testing his or her skills in listening comprehension, speaking with accuracy(精确) and resourcefulness, and writing with clarity and fluency(流畅), Jen said.
60. The United States will introduce a new exam because _______.
A. it will bring the US government quite a lot of money
B. the Chinese people pay special attention to English studies
C. the already existing exam systems seem to be far from perfect
D. more and more students want to get further education in the USA
61. Which of the following statements is TRUE according to the selection？
A. The TOEFL is more popular with the Chinese than the IELTS.
B. It will take quite a period of time for people to accept the APIEL.
C. Chinese students will prefer the IELTS rather than the APIEL even in the future.
D. A student will have to take the APIEL if he or she wants to study in English-speaking
countries.
62. The best title for this news report is_____.
A. New Exam Designed for Students B. The Key to Improving Your English
C. TOEFL, IELTS and GRE to be Out of Date D. The Four Skills in Learning English

第三部分阅读理解（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A
Fifty years from now the world’s population will be declining, with no end in sight. Unless people’s values change greatly, several centuries from now there could be fewer people living in the entire world than live in the United States today. The big surprise of the past twenty years is that in not one country did fertility (生育能力) stop falling when it reached the replacement rate（出生率）—2.1 children per woman. In Italy, for example, the rate has fallen to 1.2. In Western Europe as a whole and in Japan it is down to 1.5. The evidence now indicates that within fifty years or so world population will peak at about eight billion before starting a fairly rapid decline.
Because in the past two centuries world population has increased from one billion to nearly six billion, many people still fear that it will keep “exploding” until there are too many people for the earth to support. But that is like fearing that your baby will grow to 1,000 pounds because its weight doubles three times in its first seven years. World population was growing by two percent a year in the 1960s; the rate is now down to one percent a year, and if the patterns of the past century don’t change completely, it will head into negative numbers. This view is coming to be widely accepted among population experts, even as the public continues to focus on the threat of uncontrolled population growth.
As long ago as September of 1974 Scientific American published a special issue on population that described what demographers (人口统计学家) had begun calling the “demographic transition” from traditional high rates of birth and death to the low ones of modern society. The experts believed that birth and death rates would be more or less equal in the future, as they had been in the past, keeping total population stable after a level of 10-12 billion people was reached during the transition.
56. Which of the following statement is NOT true according to the passage?
A. The world’s population in the future will be reducing endlessly.
B. When the earth population reaches 8 billion, it will see a rapid decrease.
C. In modern society the birth and death rates will be more or less equal in the future.
D. The public now pay little attention to the threat of uncontrolled population growth.
57. What’s reason for the sharp increase of world population in the past two centuries?
A. Because people fear that the world will explode.
B. Because the world’s replacement rate keeps falling.
C. Because people’s values has greatly changed.
D. The passage doesn't mention it.
58. The expression “demographic transition” (Paragraph 3) probably means _______.
A. high death rate to the low one
B. high birth rate to the low one
C. high rates of birth and death to the low ones
D. low rates of birth and death to the high ones
59. We can learn from the passage that _______.
A. in the near future there will be a rapid decline of the world population
B. the birth and death rates of modern society will be unequal in the future
C. there would be the same population living in the world than it in the US today
D. in Western Europe the replacement rate has declined to a negative number

The “Monday morning feeling” could be a crushing pain in the chest which leaves y
ou sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.
　The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2600 Germans showed that the average person had a 20 percent high chance of having a heart attack on a Monday than on any other day.
　 Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.
　A study of 11000 Italians proved 8 a.m. on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries.
　The findings could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol (胆固醇) but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them,” he said.
　Monday mornings have a double helping of stress for the working body as it makes rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.
　“When people get up, their blood pressure and heart rate go up and there are hormonal (内分泌) changes in their bodies,” Willich explained. “ All these things can have an unfavorable effect in the blood system and increase the risk of a clot (血凝块) in the arteries (动脉) which will cause a heart attack.
　 “When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activity,” said Willich.

Work is a very important part of life in the United States. Americans spend most of their lives working. For most Americans, their work defines them. They are what they do. What happens, then, when a person can no longer work?
Most Americans stop working at the age of sixty-five or seventy and retire. Because work is such an important part of life in this culture, retirement can be very difficult. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire, but leaving one’s job, whatever it is, is a difficult change, even for those who look forward to retiring. Retirement can also bring financial problems. Many people depend on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. When people retire, they receive this money as income. These checks do not provide enough money to live on, however, because prices are increasing very rapidly. Senior citizens, those over sixty-five have to have savings in the ban or other retirement plans to make ends meet. The rate of inflation is forcing prices higher each year. Social Security checks alone can not cover these growing expenses. The government offers some assistance, but many senior citizens have to change their life styles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities.
Of course, many senior citizens are happy with their retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part time, others do volunteer work. Some, like those in the Retired Business Executive Association, even help old people to get started in new businesses. Many retired citizens also belong to “Golden Age” groups. These organizations plan trips and social events there are many other opportunities for retirees.
