单选题To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high offices. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France and later on in England. By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn"t until the twentieth century that women"s umbrellas began to be made in a whole variety of colors.

单选题There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal combustion engine (内燃机) has something to do with burning fuel, expanding gases and pistons (活塞) being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computer's impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy (读写能力); it is a trade skill that should not be taught as a liberal art. Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repair and violin-making. Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more "user-friendly". Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase "learning to use a computer" mean? It rounds like "learning to drive a car", that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer. In fact, "learning to use a computer" is much more like "learning to play a game", but learning the rules of one game may not help you play a second game, whose rules may not be the same. There is no such thing as teaching someone how to use a computer, One can only teach people to use this or that program and generally that is easily accomplished.

单选题{{B}}Directions:{{/B}} There are 5 reading passages in this part. 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 and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets.{{B}}Passage 1{{/B}} Although vocal cords are lacking in cetaceans, phonation is undoubtedly centered in the larynx. The toothed whales or odontocetes (sperm whales and porpoises) are much more vociferous than the whalebone whales, or mysticetes. In this country observers have recorded only occasional sounds from two species of mystieetes (the humpback and right whale). A Russian cetologist reports hearing sounds from at least five species of whalebone whales but gives no details of the circumstances or descriptions of the sounds themselves. Although comparison of the sound-producing apparatus in the two whale groups cannot yet be made, it is interesting to note that the auditory centers of the brain are much more highly developed in the odontocetes than in the mystieetes, in fact, to a degree unsurpassed by any other mammalian group.

单选题73.5 percent of major U.S. firms report that they record and review their employees" communications and activities on the job. The larger the company, the more likely it is to engage in monitoring and surveillance activities, according to a survey. Broken down by business category, survey respondents in the financial services sector lead the packs when it comes to monitoring their employee"s e-mail and Internet connections. Weber says he sees companies go through a "life cycle" with their Internet experience. When they first get connected, companies see a surge of activity and an immediate drop-off in productivity. After about two or three weeks, Internet use levels off, Weber notes. Weber observes that among his clients, he"s seeing a trend where employers are letting the lifecycle run its course. In other cases, Weber says his clients are capturing the information, but not really doing anything about it. One thing the experts all agree on is that if you use the Internet and provide access to your employees, you should have a policy in place that defines what you deem to be permissible use by employees. Weber believes that no company wants to be in the rote of Big Brother, but still must protect one of its most valuable assets. Nor are employers looking to micro-manage their employees. Many companies are viewing use of the Internet as similar to the phone, and operating with the philosophy that incidental personal use is okay. "But some clients don"t see a need to restrict access," he explains. For certain the issues that surround monitoring employee Internet use aren"t going to quiet down anything soon, the experts say. "Maybe the simplest solution is to just allow a certain percentage to go to employee use."

单选题{{B}}Passage 4{{/B}} The examples placed before a nation are vital. What we constantly observe, we tend to copy. What we reward, we perpetuate. This is why John Glenn himself is almost as important as his flight into outer space, for he dramatized before the eyes of the whole nation the noblest qualities of the human spirit. Outside of the morality-play of our cowboy movies, where the hero always gets the girl and the villain always gets slugged behind the saloons, courage, modesty, quiet patriotism, love of family and religious faith are not exactly the predominant themes of our novels, plays, TV shows, movies or newspapers these days. Yet Glenn dramatized them all coast to coast and around the world. This was no insensitive robot who landed here from the heavens yesterday morning, but a warm and thoughtful human being: natural, orderly, considerate and, at times, quietly amusing and even eloquent. His departure from Cape Canaveral was a technical triumph, but his return was a human triumph. This memorable performance, of course, may not stamp out juvenile delinquency overnight, but the models of the nation--not the uncovered cover girls of today but the larger models of human character--are probably more important than this age believes. When Walter Bagehot, the English editor and scientist, made his famous study 100 years ago of why some nations progressed, he concluded that what a nation admired and despised was almost as important as its military power. "Slighter {{B}}causes{{/B}} than is commonly thought," he said, "may change a nation from the stationary to the progressive state of civilization, and from the stationary to the degrading." It all depended, he insisted, on the model of character emulated or eliminated. If this was true in the middle of the nineteenth century it has even more validity in this age of instantaneous communication. Only a few hundred people heard Lincoln's Gettysburg Address. New models and styles are now set by television every day, but most of them are models of cars and styles of dresses and hairdos. What transcontinental television did for the nation on the Glenn story illustrates the wider application of the idea. It almost made up for what it does to us the rest of the time, but not quite. Meanwhile, the question remains: how many more John Clenns and A1 Shepards are hiding in this country? Outer space is a long way to go to discover a new generation of leaders of men, but if we have to recruit them there, why not? {{B}}Human weightlessness{{/B}} is almost our major problem in Washington and, since these astronauts know more about it than anybody else, maybe a couple of them should be transferred to the thin hot air of the capital. After all, Glenn is 40 and even if he looks like the freshman football coach at Muskingum College he can't go off spinning around the earth without his Annie forever. Once Christopher Columbus had discovered America, Ferdinand and Isabella didn't insist that he go back every Tuesday. Besides, is the moon worth John Glenn when we need him so badly on earth?

单选题In the past few decades, remarkable findings have been made in ethology, the study of animal social behavior. Earlier scientists had (21) that nonhuman social life was almost totally instinctive or fixed by genetics. Much more careful observation has shown that (22) variation occurs among the social ties of most species, showing that learning is a part of social life. That is, the (23) are not solely fixed by the genes (24) , the learn ing that occurs is often at an early age in a process that is called imprinting. Imprinting is clearly (25) instinctive, but it is not quite like the learning of humans; it is something in between the two. An illustration best (26) the nature of imprinting. Once, biologists thought that ducklings followed the mother duck because of instincts. Now we know that, shortly (27) they hatch, ducklings fix (28) any object about the size of a duck and will henceforth follow it. So ducklings may follow a basketball or a briefcase if these are (29) for the mother duck at the time when imprinting occurs. Thus, social ties can be considera bly (30) , even ones that have a considerable base (31) by genetics. Even among the social insects something like imprinting (32) influence social behav ior. For example, biologists once thought bees communicated with others purely (33) in stinct. But, in examining a "dance" that bees do to indicate the distance and direction of a pollen source, observers found that bees raised in isolation could not communicate effec tively. At a higher level, the genetic base seems to be much more for an all-purpose learn ing rather than the more specific responses of imprinting. Chimpanzees, for instance, gen erally (34) very good mother but Jane Goodali reports that some chimps carry the infant upside down or (35) fail to nurture the young.
