Script: The rat race is often thought of as being associated with the corporate environment where the company tries to squeeze the most productivity out of its workers.

With a definition like that, it is no wonder that many people in our frenetic (忙乱的) modern life begin to question our attitudes about work and begin seeking better alternatives to escape the rat race. Can one make a living if one is to leave the rat race? How?

One way is to become self-employed and work for oneself — such as a freelance (自由职业的) writer, web designer, consultant, etc. Another is to switch to a less demanding job, to a job where one is following one’s passion, or to a job that requires less hours.

Section B

Directions: There are several passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice.

Passage One

Questions 31 to 35 are based on the following passage.

A new era is coming with a fundamental change in the way of work, in our industrialized world. Call it what you will: the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we’re partly there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more and more part-time jobs, and a growing number of people who are self-employed. But the breadth of the economic transformation can’t be measured by numbers alone, because it also is giving rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers — all these are being challenged.

We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip (集成块), would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow’s achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic

changes like the invention of the microchip. But one thing is certain: information and knowledge will become even more vital, and people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write.

So the whole world will be computerized and some people will adapt, others won’t. But hopefully not all work will be equal. Some people argued, that people no longer should be classified as white or blue collar, manager or laborer, but rather as knowledge and service workers. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. But there will be a future in manufacturing, and the reason for that, is the move away from standardized production and toward more flexible, customized manufacturing. To survive, the workers have to think of new ways to meet the changing demands of customers.

31.

A characteristic of the information age is that ________.

A) the service industry is relying more and more on the female work force B) manufacturing industries are steadily increasing

C) people find it harder and harder to earn a living by working in factories D) most of the job opportunities can now be found in the service industry

正确答案： D 32.

One of the great changes brought about by the knowledge society is that ________. A) the difference between the employee and the employer has become insignificant B) people’s traditional concepts about work no longer hold true C) most people have to take part-time jobs

D) people have to change their jobs from time to time

正确答案： B 33.

By referring to computers and other inventions, the author means to say that ________. A) people should be able to respond quickly to the advancement of technology

B) future achievements in technology will bring about inconceivable dramatic changes C) the importance of high technology has been overlooked

D) computer science will play a leading role in the future information services

正确答案： B 34.

The future will probably belong to those who ________. A) possess and know how to make use of information B) give full play to their brain potential

C) involve themselves in service industries

D) cast their minds ahead instead of looking back

正确答案： A 35.

Which of the following would be the best title for the passage? A) Computers and the Knowledge Society B) Service Industries in Modern Society C) Features and Implications of the New Era

D) Rapid Advancement of Information Technology

正确答案： C

Passage Two

Questions 36 to 40 are based on the following passage.

When global warming finally came, it stuck with a vengeance. In some regions, temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet, flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America, Europe and Asia. After driving many of the animals around them to near extinction, people were forced to abandon their old way of life for a radically new survival strategy that resulted in widespread starvation and disease. The adaptation was farming: the global-warming crisis that gave rise to it happened more than 10,000 years ago. As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future, earth scientists are in the midst of a revolution in understanding how climate has changed in the past — and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have combined to change the planet’s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of year.

Most importantly, scientists are beginning to realize that the climatic changes have had a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution: from the dawn of primates (灵长目动物) some 65 million years ago to human ancestors rising up to walk on two legs, from the huge expansion of the human brain to the rise of agriculture. Indeed, the human history has not been merely touched by global climate change, some scientists argue, it has in some instances been driven by it.

The new research has profound implications for the environmental summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign (宜人的) global environment that has existed over the past 10,000 years — during which agriculture, writing, cities and most other features of civilization appeared — is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact, the

pattern or climate change in the past reveals that Earth’s climate will almost certainly go through dramatic changes in the future — even without the influence of human activity.

36.

Farming emerged as a survival strategy because man had been obliged _______________. A) to give up his former way of life B) to leave the coastal areas

C) to follow the ever-shifting vegetation D) to abandon his original settlement

正确答案： A 37.

Earth scientists have come to understand that climate _______________. A) is going through a fundamental change B) has been getting warmer for 10,000 years C) will eventually change from hot to cold D) has gone through periodical changes

正确答案： D 38.

Scientists believe that human evolution _______________. A) has seldom been accompanied by climatic changes B) has exerted little influence on climatic changes C) has largely been affected by climatic changes D) has had a major impact on climatic changes

正确答案： C 39.

Evidence of past climatic changes indicates that _______________. A) human activities have accelerated changes of Earth’s environment B) Earth’s environment will remain mild despite human interference C) Earth’s climate is bound to change significantly in the future

D) Earth’s climate is unlikely to undergo substantial changes in the future

正确答案： C 40.

The message the author wishes to convey in the passage is that _______________. A) human civilization remains glorious though it is affected by climatic changes B) mankind is virtually helpless in the face of the dramatic changes of climate

C) man has to limit his activities to slow down the global warming process D) human civilization will continue to develop in spite of the changes of nature

正确答案： B

正确答案： B

Passage Two

Questions 36 to 40 are based on the following passage.

Imagine eating everything delicious you want — with none of the fat. That would be great, wouldn’t it?

New “fake fat” products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra (人造脂肪), say food manufacturers can now eliminate fat from certain foods. Critics, however,

countries? Pop stars earn vast sums in foreign currency — often more than large industrial concerns — and the taxman can only be grateful for their massive annual contributions to the national treasury. So who would begrudge them their rewards?

People who make envious remarks should remember that the most famous stars represent only the tip of the iceberg. For every famous star, there are hundreds of others struggling to earn a living. A man working in a steady job and looking forward to a pension at the end of it has no right to expect very high rewards. He has chosen security and peace of mind, so there will always be a limit to what he can earn. But a man who attempts to become a star is taking enormous risks. He knows at the beginning that only a handful of competitors ever get to the very top. He knows that years of concentrated effort may be rewarded with complete failure. But he knows, too, that the rewards for success are very high indeed: they are the recompense for the huge risks involved and if he achieves them, he has certainly earned them. That’s the essence of private enterprise.

31.

The sentence “Pop stars today enjoy a style of living which was once the prerogative only of Royalty” means ____________.

A) their life is as luxurious as that of royalty

B) they enjoy what once only belonged to the royalty C) they are rather rich

D) their way of living is the same as that of the royalty

正确答案： B 32.

What is the author’s attitude toward top stars’ high income? A) Approval. B) Disapproval. C) Ironical. D) Critical.

正确答案： A 33.

What can be inferred from the last paragraph?

A) There exists fierce competition in climbing to the top. B) People are blind in idolizing stars.

C) Successful pop stars give great entertainment. D) The tax the pop stars have paid is great.

正确答案： A 34.

From the passage, we can learn that _________________. A) successful men should get high-income repayment B) pop stars make a great contribution to a country C) pop stars can enjoy the life of royalty

D) successful men represent the tip of the iceberg

正确答案： D 35.

Which paragraph covers the main idea? A) The first. B) The second. C) The third. D) The fourth.

正确答案： D

Passage Two

Questions 36 to 40 are based on the following passage.

Imagine eating everything delicious you want — with none of the fat. That would be great, wouldn’t it?

New “fake fat” products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra (人造脂肪), say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it’s up to consumers to decide whether the new fat-free products taste good enough to keep eating.

Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.

Normally, special chemicals in the intestines (肠) \and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.

The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E, and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.

Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being

absorbed. It can also prevent the absorption of carotenoids (类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.

Manufacturers are adding vitamins A, D, E, and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.

36.
