单选题For most thinkers since the Greek philosophers, it was self-evident that there is something called human nature, something that constitutes the essence of man. There were various views about what constitutes it, but there was agreement that such an essence exists—that is to say, that there is something by virtue of which man is man. Thus man was defined as a rational being, as a social animal, an animal that can make tools, or a symbol-making animal. More recently, this traditional view has begun to be questioned. One reason for this change was the increasing emphasis given to the historical approach to man. An examination of the history of humanity suggested that man in our epoch is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called "human nature". The historical approach was reinforced, particularly in the United States, by studies in the field of cultural anthropology. The study of primitive peoples has discovered such a diversity of customs, values, feelings, and thoughts that many anthropologists arrived at the concept that man is born as a blank sheet of paper on which each culture writes its text. Another factor contributing to the tendency to deny the assumption of a fixed human nature was that the concept has so often been abused as a shield behind which the most inhuman acts are committed. In the name of human nature, for example, Aristotle and most thinkers up to the eighteenth century defended slavery. Or in order to prove the rationality and necessity of the capitalist form of society, scholars have tried to make a case for acquisitiveness, competitiveness, and selfishness as innate human traits. Popularly, one refers cynically to "human nature" in accepting the inevitability of such undesirable human behavior as greed, murder, cheating and lying. Another reason for skepticism about the concept of human nature probably lies in the influence of evolutionary thinking. Once man came to be seen as developing in the process of evolution, the idea of a substance which is contained in his essence seemed untenable. Yet I believe it is precisely from an evolutionary standpoint that we can expect new insight into the problem of the nature of man.

单选题The media can impact current events. As a graduate student at Berkeley in the 1960s, I remember experiencing the events related to the People's Park that were occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impression of what was going on with perceptions obtained from the news media. I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities. Electronic media are having a greater impact on the people's lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a global village, or what one writer calls the electronic city. Consider the information that television brings into your home every day. Consider also the contact you have with others simply by using telephone. These media extend your consciousness and your contact. For example, the video coverage of the 1989 San Francisco earthquake focused on "live action" such as the fires or the rescue efforts. This gave the viewer the impression of total disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened. This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities. In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles, seemingly fed by video coverage from helicopters. This event was triggered by the verdict (裁定) in the Rodney King beating. We are now in an age where the public can have access to information that enables it to make its own judgements, and most people, who had seen the video of this beating, could not understand how the jury (陪审团) was able to acquit (宣布……无罪) the policemen involved. Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as it seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television pleading, "Can we all get along?" By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools. Because of that, many more people turned out to join the peaceful event they saw unfolding on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.

单选题Sequoyab was a young Cherokee Indian, son of a white trader and an Indian Squaw (北美印第安女人). At an early age, he became fascinated by "tile talking leaf", an expression that he used to describe the white man's written records. Although many believe this "talking leaf" to be a gift from tile Great Spirit, Sequoyah refused to accept that theory. Like other Indians of tile period, he was illiterate, but his determination to remedy tile situation led to the invention of a unique 86 character alphabet based on the sound patterns that he heard. His family and friends thought him mad, but while recuperating (恢复) from a hunting accident, he diligently and independently set out to create a form of communication for his own people as well as for other Indians. In 1821, after twelve years of work, he had successfully developed a written language that would enable thousands of Indians to read and write. Sequoyah's desire to preserve words and events for later generation has caused him to be remembered among the important inventors. The giant redwood trees of California, called "sequoias (红杉)" in his honor, will further imprint his name in history.

单选题{{B}}Text 3{{/B}} The right to pursue happiness is promised to Americans by the US Constitution, but no one seems quite sure which way happiness ran. It may be we are issued a hunting license but offered no game. Jonathan Swift conceived of happiness as "the state of being well-deceived", or of being "a fool among idiots", for Swift saw society as a land of false goals. It is, of course, un-American to think in terms of false goals. We do, however, seem to be dedicated to the idea of buying our way to happiness. We shall all have made it to Heaven when we possess enough. And at the same time the forces of American business are hugely dedicated to making us deliberately unhappy. Advertising is one of our major industries, and advertising exists not to satisfy desires but to create them—and to create them faster than anyone's budget can satisfy them. For that matter, our whole economy is based on addicting us to greed. We are even told it is our patriotic duty to support the national economy by buying things. Look at any of the magazines that cater to women. There advertising begins as art and slogans in the front pages and ends as pills and therapy in the back pages. The art at the front illustrates the dream of perfect beauty. This is the baby skin that must be hers. This, the perfumed breath she must breathe out. This, the sixteen-year-old figure she must display at forty, at fifty, at sixty, and forever. This is the harness into which Mother must strap herself in order to display that perfect figure. This is the cream that restores skin, these are the tablets that melt away fat around the thighs, and these are the pills of perpetual youth. Obviously no reasonable person can be completely persuaded either by such art or by such pills and devices. Yet someone is obviously trying to buy this dream and spending billions every year in the attempt. Clearly the happiness-market is not running out of customers, but what is it they are trying to buy? Defining the meaning of "happiness" is a perplexing proposition: the best one can do is to try to set some extremes to the idea and then work towards the middle. To think of happiness as achieving superiority over others, living in a mansion made of marble, having a wardrobe with hundreds of outfits, will do to set the greedy extreme.

单选题What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special-purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manual driven cars. A special-purpose 1ane system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway (高速公路) capacity. Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just before reaching the automated highway. If a mixed traffic system way was in place, automated driving could begin whenever the driver was on suitably equipped roads. If special-purpose lanes were available, the car could enter them and join existing traffic in two different ways. One method would use a special onramp (入口引道). As the driver approached the point of entry for the highway, devices installed on the roadside would electronically check the vehicle to determine its destination and to ascertain that it had the proper automation equipment in good working order. Assuming it passed such tests, the driver would then be guided through a gate and toward an automated lane. In this case, the transition from manual to automated control would take place on the entrance ramp. An alternative technique could employ conventional lanes, which would be shared by automated and regular vehicles. The driver would steer onto the highway and move in normal fashion to a "transition" lane. The vehicle would then shift under computer control onto a lane reserved for automated traffic. [The limitation of these lanes to automated traffic would, presumably, be well respected, because all trespassers (非法进入者) could be swiftly identified by authorities. ] Either approach to joining a lane of automated traffic would harmonize the movement of newly entering vehicles with those already traveling. Automatic control here should allow for smooth merging without the usual uncertainties and potential for accidents. And once a vehicle had settled into automated travel, the driver would be free to release the wheel, open the morning paper or just relax.
