Passage 1

Science fiction (SF) can provide students interested in the future with a basic introduction to the concept of thinking about the possible futures in a serious way, a sense of emotional forces in their own culture that are affecting the shape the future may take, and a multitude of extrapolations

研究公共英语考试

(prediction) regarding the results of present trends . There is one particular type of story that can be especially valuable as a stimulus to discussion of these issues both in courses on the future and in social science courses in general----the story which presents well-worked-out, detailed societies that differ significantly from the society of the reader. In fact, whatever the reliability of its predictions, SF is actually a more important vehicle for speculative visions about macroscopic social change. At this level, it is hard to deal with any precision as to when general value changes or evolving social institutions might appear, but it is most important to think about the kinds of societies that could result from the rise of new forms of interaction, even if one cannot predict exactly when they might occur.

In performing this “what if …” function, SF can act as a social laboratory as authors ruminate upon (think about) the forms social relationships could take if key variables in their own societies were different, and upon what new belief systems or mythologies could arise in the future to provide the basic rationalizations for human activities. If it is true that more people find it difficult to conceive of the ways in which their society, or human nature itself, could undergo fundamental changes, then SF of this type may provoke one’s imagination to consider the diversity of paths potentially open to society.

Moreover, if SF is the laboratory of the imagination, its experiments are often of the kind that may significantly alter the subject matter even as they are being carried out. That is, SF has always had a certain cybernetic effect on society, as its visions emotionally engage the future-consciousness of the mass public regarding especially desirable and undesirable possibilities. The shape a society takes in the present is in part influenced by its image of the future; in this way particularly powerful SF images may become self-fulfilling or self-avoiding prophecies for society. For that matter, some individuals in recent years have even shaped their own life-styles after appealing models provided by SF stories. The reincarnation (reappearance) and diffusion of SF futuristic images of alternative societies through the media of movies and television may have speeded up an augmented SF’s social feedback effects. Thus SF is not only change speculator but change agent, sending an echo form the future that is becoming into the present that is sculpting it. This fact alone makes imperative in any education system the study of the kinds of works discussed in this section.

It must be noted that this perspective of SF has been questioned by some critics. It is often pointed out that, however ingenious they may be about future technologies, many SF writers exhibit an impact conservative bias in their stories, insofar as social projections (new ideas ) are either ignored or based on variations of the present status quo or of historical social systems reshuffled whole-cloth into the future. Robert Bloch has conveniently summarized the kind of future society presented by the average SF writer as consisting of a totalitarian state in which psychochemical techniques (the use of mind- altering drugs) keep the populace quiet; an underground which the larger-than-life hero can join; and scientists who gladly turn over their discoveries to those in power. Such tales covertly assume that human nature as we know it will remain stable and that twentieth-century Anglo-American culture and moral values, especially traditional economic incentives, will continue to dominate the world. Most SF authors have found it as hard as most other mortals to extrapolate (guess)social mores different from those operating within their own milieu (environment), so that, it has been charged, far from preparing the reader for future shock, SF is a literature that comfortably and smugly reassures him that the future will not be radically different from the present.

研究公共英语考试

There is much truth to this analysis of SF. It is not easy to explain why so many stories seem to take as their future social settings nothing more ambiguous than the current status quo or its totally evil variant. Part of the answer may be that many authors of commercial SF writing received their professional training in science and engineering prior to World War II and were therefore not equipped or inclined to devise sophisticated social backgrounds in their plots. Be that as it may, the situation has changed dramatically in recent decades. There are an increasing number of stories which explicitly assume that future social patterns of family, government, religion, and the like need not be exactly the same as those of the present and that the forces which motivate men may also be subject to change. It is from such stories, and their predecessors in classical SF, that one may study examples of the impact of SF on the individual and collective imagination.

Passage 2

1 Many years ago trying to help people with every kind of trouble left me with In case after case the difficulty could have been overcome --- or might never have arisen --- if the people involved had just treated one another with common courtesy.

2 Courtesy, politeness, good manners --- call it what you will, the supply never seems to equal the demand. “It’s not so much what my husband says,” a tearful wife confides, “as the way he says it. Why does he have to yell at me?” “I hate my boss,” a grim-faced office worker mutters. “He never shows appreciation for anything.” “All we get from our teenagers,” a harassed parent says, “is a sullen surliness.”

3 Such complaints are not limited to people who sit in my study. Human beings everywhere hunger for courtesy. “Good manners,” said Ralph Waldo Emerson, “are the happy way of doing things.” And the reverse is equally true. Bad manners can ruin a day --- or wreck a friendship.

4 What are the basic ingredients of good manners? Certainly a strong sense of justice is one; courtesy is often nothing more than a highly developed sense of fair play. A friend once told me of driving along a one-lane, unpaved mountain road. Ahead was another car that produced clouds of choking dust, and it was a long way to the nearest paved highway. Suddenly, at a wider place, the car ahead pulled off the road. Thinking that its owner might have engine trouble, my friend stopped and asked if anything was wrong. “No,” said the other driver. “But you’ve endured my dust this far; I’ll put up with yours the rest of the way.” There was a man with manners, and an innate sense of fair play.

5 Another ingredient of courtesy is empathy, a quality that enables a person to see into the mind or heart of someone else, to understand the pain or unhappiness there and to do something to minimize it. Recently in a book about a famous restaurant chain I came across such an episode.

6 A man dining alone was trying to unscrew the cap of a bottle of catsup but his fingers were so badly crippled by arthritis that he couldn’t do it. He asked a young busboy to help him. The boy took the bottle, turned his back momentarily and loosened the cap without difficulty. Then he tightened it again. Turning back to the man, he feigned a great effort to open the bottle without success. Finally he took it into the kitchen and returned shortly, saying that he had managed to loosen it --- but only with a pair of pliers. What impelled the boy to take so much trouble to spare the feelings of a stranger? Courtesy, compassionate courtesy.

7 Yet another component of politeness is the capacity to treat all people alike, regardless of all status or importance. Even when you have doubts about some people, act as if they are worthy of your best manners. You may also be astonished to find out that they really are.

8 I truly believe that anyone can improve his or her manners by doing 3 things. First, by practicing courtesy. All skills require constant repetition to become second nature; good manners are no exception.

9 One simple way is to concentrate on your performance in a specific area for about a week. Telephone manners, for example. How often do you talk too long, speak abruptly, and fail to identify yourself, keep people waiting, display impatience with the operator or fail to return a call?

10 One difficult but essential thing to remember is to refuse to let other people’s bad manners father one night when a driver in an oncoming vehicle failed to dim his lights. “Give him the

研究公共英语考试

brights, Dad!” the young man urged in exasperation. “Son,” replied the father, “that driver is certainly discourteous and probably stupid. But if I give him the brights he’ll be discourteous, stupid and blind --- and that’s a combination I don’t want to tangle with!”

11 The second requirement for improving your manners is to think in a courteous way. In the long run, the kind of person you are is the result of what you’ve been thinking over the past 20 or 30 years. If your thoughts are predominantly self-directed, a discourteous person is what you will be. If on the other hand you train yourself to be considerate of others, if you can acquire the habit of identifying with their problems and hopes and fears, good manners will follow almost automatically.

12 Nowhere is thinking courtesy more important than in marriage. In the intimacy of the home it is easy to displace disappointment or frustration or anger onto the nearest person, and that person is often a husband or wife.

13 “When you feel your anger getting out of control,” I have often said to married couples, “force yourself for the next ten minutes to treat your married partner as if he or she were a guest in your home,” I knew that if they could impose just 10 minutes of good manners on themselves, the worst of the storm would blow over.

14 Finally, to have good manners you must be able to accept courtesy, receive it gladly, Strangely, some people are suspicious of gracious treatment. They suspect the other person of having some ulterior motive.

15 But some of the most precious gifts in life come You can’t achieve a beautiful day through any effort on your part. You can’t buy a sunset or even the scent of a rose. Those are the world’s courtesies to us, offered with love and no thought of reward or return. Good manners are, or should be, like that.

16 In the end, it all comes down to how you regard people --- not just people in general, but individuals. Life is full of minor irritations and trials and injustices. The only constant, daily, effective solution is politeness --- which is the golden rule in action. I think that if I were allowed to add one small beatitude as a footnote to the other it might be: Blessed are the courteous.

Science and Humanity

The twentieth century saw more momentous change than any previous century: change for better, change for worse; change that brought enormous benefits to human beings, change that threatens the very existence of the human species. Many factors contributed to this change but—in my opinion—the most important factor was the progress in science.

Academic research in the physical and biological sciences has vastly broadened our horizons; it has given us a deep insight into the structure of matter and of the universe; it has brought better understanding of the nature of life and of its continuous evolution. Technology—the application of science—has made fantastic advances that have affected us beneficially in nearly every aspect of life: better health, more wealth, less drudgery (单调沉闷的工作), greater access to information.

Sadly, however, there is another side to the picture. The creativity of science has been employed to the detriment(损害) of mankind. The application of science and technology to the development and manufacture of weapons of mass destruction has created a real threat to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons. Although their actual use in combat has so far occurred only in 1945—when two Japanese cities were destroyed— during the four decades of the Cold War, obscenely huge arsenals(武器库) of nuclear weapons were accumulated and made ready for use. The arsenals were so large that if the weapons had actually been detonated (爆炸) the result could have been the complete extinction of the human species, as well as of many animal species.

William Shakespeare said: "The web of our life is of a mingled (混合的) yarn, good and ill together. " The above brief review of the application of only one strand of human activities— science—seems to bear out this adage (格言). But does it have to be so? Must ill always accompany good deeds? Are we biologically programmed for aggression and war?

I am not an authority in genetics, but from my readings and life-long observation I do not see any evidence that we are genetically condemned to commit evil. On the contrary, on very general grounds I would say that genetically we are destined to do things that are of benefit to the human species, and that the negative aspects are mistakes, transient errors in the process of evolution. In

研究公共英语考试

other words, I believe in the inherent goodness of Man.

We are thus faced with a daunting (威吓，使胆怯) dilemma. As a process of natural evolution, science should be allowed to develop freely, without restrictions. But can we afford the luxury of uninhibited research in the natural sciences, with its awesome (可怕的) potential of total destruction, in a world in which war is still a recognized social institution?

The preservation of the human species and its continuing enhancement demand that we learn to live with one another in peace and harmony. But this learning process has been slow and arduous (费力的), and is not yet complete. Due to the harsh conditions under which primitive man lived, he often had to fight with other human beings for survival. Individual killing and, later, collective killing—war—thus began to be seen as a natural phenomenon.

We are still not organized for a war-free world. But in the meantime, the human species may be brought to an end by the use of the tools of destruction, themselves the product of science and technology.

In my opinion, the problem has to a large extent arisen from the uneven rate of advance in the different areas of human activities, in particular, between the progress in the natural sciences—which include the physical and biological disciplines, and the various social sciences—economics, sociology, politics (with psychology perhaps at the interface between the two major groups). Undoubtedly, there has been much faster progress in the natural sciences than in the social ones.

Why have the natural sciences, especially the physical sciences, advanced so much faster than the social sciences? It is not because physicists are wiser or cleverer than, say, economists. The explanation is simply that physics is easier to master than economics. Although the material world is a highly complex system, for practical purposes it can be described by a few general laws. The laws of physics are immutable (不可改变的). They apply everywhere, on this planet as well as everywhere else in the universe, and are not affected by human reactions and emotions, as the social sciences are.

How can we tackle this unevenness in the rate of progress of different areas of science? Two ways come to mind: one, by accelerating the rate of progress in the social sciences; two, by slowing down the rate of advancement of the natural sciences in some areas, for example, by the imposition of ethical codes of conduct.

Clearly, the former is by far the preferable way. What we would like to see is faster progress in the social sciences, leading to the establishment of a social system which would make war not only unnecessary but unthinkable; a system in which the existence of old, or the invention of new, weapons of mass destruction, would not matter, because nobody would dream of using them; a system in which people will be able to say: “nuclear weapons: who cares?”

Responsibility for one's actions is, of course, a basic requirement of every citizen, not just of scientists. Each of us must be accountable for our deeds. But the need for such responsibility is particularly imperative for scientists, if only because scientists understand the technical problems better than the average citizen or politician. And knowledge brings responsibility.

In any case, scientists do not have a completely free hand. The general public, through elected governments, have the means to control science, either by withholding (抑制) the purse, or by imposing restrictive regulations harmful to science. Clearly it is far better that any control should be exercised by the scientists themselves, through a self-imposed code of conduct. The establishment of an ethical code of conduct for scientists is an idea whose time has come.

Passage 2

China Sees Opportunities in Climate Change

UNLIKE America’s leaders, China’s bosses are not much troubled by recalcitrant（顽强的）legislatures. The government has therefore had no difficulty in executing a smart volte face（完全改变）on climate change. Around three years ago its fierce resistance to the notion of any limit on its greenhouse-gas emissions started to soften. It now seems to be making serious efforts to control them.

One reason for this change is the country’s growing awareness of its vulnerability to a warming world. The monsoon（季风）seems to be weakening, travelling less far inland and dumping its rainfall on the coasts. As a result China is seeing floods in the south-east and droughts in the north-west. At the same time the country’s leaders are deeply concerned about the melting of the glaciers on the Tibetan plateau, which feed not just the Ganges, the Indus, the Brahmaputra and the Mekong but also the Yangzi and Yellow rivers .

A second reason is China’s growing sense of global responsibility. The country is not only the world’s largest emitter of greenhouse gases; it now regards itself, and is regarded, as one of the world’s leading powers, and therefore expects to work with the other big powers to tackle global problems such as the economic crisis, nuclear proliferation（核扩散）and climate change.

A third reason is energy security. Although China has large coal reserves, it is also a big importer. Concerns about excessive dependence on foreign fossil fuels sharpened when China’s oil imports rocketed and, in 2005, the attempt by CNOOC（China National Offshore Oil Corporation), China’s largest offshore oil and gas company, to buy America’s Unocal was rebuffed. China’s push into nuclear and renewable energy has been driven by its need to diversify its energy sources.

The fourth reason is economic. The Kyoto protocol has given China an incentive to clean up its act. China has received $2 billion through the CDM（Clean Development Mechanism) for cleaning up its industrial processes and building clean-energy capacity—half the money that has flowed through the CDM. That is expected to rise to $8 billion by 2012.

But a longer-term economic motive springs from a shift in the way China thinks about growth. In the past, its all-out drive for growth has led it to rebuff（拒绝）pressure to cut emissions. Attempts to control pollution foundered （失败） on the performance-assessment system for officials at all levels of government, which prioritises growth. But that has been adjusted to encourage energy efficiency, and at the same time the leadership has started to argue that growth and greenery are compatible.

Since Wen Jiabao took over as prime minister, the leadership has tried to define economic growth as something broader and longer-term than GDP figures imply: the emphasis has been on a “harmonious society” and “scientific development”. Nobody was sure what the latter meant, but Mr Wen has recently been talking about a more “resource-efficient environmentally friendly society” and Hu Jintao, the president, has referred several times to a “low-carbon economy” and a “green economy”.

Local pollution may help to explain the shift. Residents are infuriated by filthy air and water that kills people and damages unborn children. Policies to cut carbon-dioxide emissions—through reducing the energy used to produce goods—can help clean up China’s cities at the same time.

More interesting is the idea that clean energy might be a source of growth rather than a constraint on it. China, so the argument goes, missed out on the computer revolution. It makes hardware, but American firms own most of the valuable stuff—the intellectual property for the software. “You can’t get rich making socks and toys,” explains Lin Jiang, director of the China Sustainable Energy Programme at the Energy Foundation in San Francisco. “They’re looking for the next growth industry. Clean energy clearly has huge potential. And no country dominates the industry yet. It’s a wide-open field.” Hu Angang, an economist at Tsinghua University, calls this “a huge opportunity for China. The country will become the largest renewable-energy market, bio-energy market, clean-coal market, nuclear-power market, carbon-exchange market, environmental-technology market, low-carbon economy, exporter of low-carbon products and low-carbon-technology innovator.”

The government is giving the economy a shove in that direction. In 2006 the five-year plan set a target for a 20% cut in the energy intensity of GDP by the end of 2010. The start was slow, but by the end of last year it had managed 10% and it now looks on track for its target. According to Mr Lin, that would mean a reduction in carbon emissions of 1.5 billion tonnes per year by 2010, more than the Waxman-Markey bill’s caps for domestic industry would take out of America’s economy by 2020. China has relatively tight vehicle fuel-efficiency standards . Electric vehicles are being generously subsidised ($8,800 for a car and $73,500 for a bus) and the government plans to build the capacity to produce half a million a year by 2012.

The most visible changes have come in renewable energy. In 2005 the National People’s Congress passed legislation to offer subsidies for renewable energy—around twice the amount for coal. For wind energy, the target was set at 20GW of capacity by 2020. The subsidy generated so much building that China now expects to hit that target by the end of this year and is aiming for 150GW by 2020. “It’s like a gold rush right now,” says Mr Lin. The target for solar energy, similarly, has been raised from 1.8GW to 20GW by 2020.

To put this in context, wind currently generates only 0.4% of Chinese electricity. Coal generates 80%. And, although China’s government does not have to jump the legislative hurdles faced by America’s president, it sometimes struggles to get policy implemented on the ground. Yet if China’s many layers of government can be persuaded that green means growth, they will cleave（坚持）to this policy; and the leadership seems keen to make that happen.

China, thus, is after the same “green jobs” that Americans have been promised as part of their road to economic recovery. America has huge advantages in terms of technology and capital, but China has a couple of things going for it too: cheaper labour and a leadership unconstrained by the need to get re-elected every four years. China can play a long game, which helps when dealing with climate change.
