单选题{{B}}Passage One{{/B}} The beat generation mainly referred to the youth who were born and brought up around the Second World War. They showed their disdain (蔑视，轻视) for almost everything traditional, such as government authority, respect for parents, one's duty, moral standards, and traditional customs. They developed a kind of absolute individualism and liberty. They preferred long hair, mini dresses or close fitting clothes to show off the figure. They advocated freedom of sex and cohabitation (同居). Their influence could be seen from the fact that about one third of the American couples living together were not married by law. And the divorce rate was very high. The endless US wars abroad and sharp class straggle at home caused many American youths to develop a kind of cynicism. They doubted the existing social system, possibility of harmonious (和谐的) human relations, and the long honored standard for correct behavior. They felt society overlooked their needs. Therefore, they refused to do any duty that was required of them by society. They declared "Don't believe anyone over thirty." All this came from the sick society. It's wrong to imagine they all fought against capitalism in support of revolutionary things. Some of their ideas were even more decadent (颓废的) and impractical. It was an abnormal phenomenon in an abnormal society.

单选题Text 3 Because some resources must be allocated at the national level, we have created policies which reflect the aggregated attributes of our society. The federal budget determines the proportion of federal resources to be invested in social welfare programs and how these resources are distributed among competing programs. The budget is arrived at through a reiterative aggregative political process which mediates the claims of groups interested in health, education, welfare, and so on, thus socializing the continuing conflict generated by their separate aspirations. The test of whether a policy is "good" under this system is whether it can marshal sufficient legitimacy and consent to provide a basis for cohesion and action. Technical criteria may play a role in the process, but the ultimate criteria are political and social. Whether a policy that is "good" in the aggregate sense is also "good" for a particular person, however, is a different matter. If everyone had identical attributes, these criteria of goodness would produce identical outcomes. Any policy negotiated to attain an aggregate correctness will be wrong for every individual to whom the policy applies. The less a person conforms to the aggregate, the more wrong it will be. When a policy is not working, we normally assume that the policy is right in form but wrong in content. It has failed because insufficient intelligence has informed its construction or insufficient energy its implementation. We proceed to replace the old policy by a new one of the same form. This buys time, since some time must elapse before the new policy can fully display the same set of symptoms of failure as the old. We thus continue to invest our time, energy, and other resources as if every new discovery of a nonworking policy is a surprise, and a surprise that can be corrected with some reorganized model. But if policies based on complex, aggregated information are always wrong with respect to the preferences of every person to whom they apply, we should concentrate on limiting such policies to minima or "floors". Rather than trying for better policies, we should try for fewer policies or more limited aggregated ones, such limitations could be designed to produce policies as spare and minimal as possible, for the resources not consumed in their operation would then be usable in non-aggregative, person-specific ways—that is, in a disaggregated fashion. This will require more than just strengthened "local" capacity; it will require the development of new procedures, institutions, roles, and expectations.

单选题The economy in the United States is heavily dependent on aluminum, a material widely used in the construction of buildings and in making such diverse things as cars, airplanes, and food containers. In 1979 Americans used over five million tons of new aluminum, and one and a half million tons of recycled aluminum. Some ninety percent of the bauxite (矾士) ore from which new aluminum is normally derived had to be imported to meet the demand. Poorer ores are abundant in the United States, however, researchers at Purdue University may recently have found a way to obtain aluminum magnetically from these. Although aluminum is not attracted by ordinary magnets, under special conditions it becomes temporarily "paramagnetic", or very weakly responsive to a magnetic field. This is achieved by immersing ore particles in water to which certain salts have been added and then filtering the ore through steel wool in the presence of a strong magnetic field. It is hoped that this technique will reduce the amount of high-grade aluminum the United States must import.

单选题The question of ethics in the legal profession is one that has plagued the industry since its inception. The common image of an attorney is one who will resort to any unethical trick to twist the laws to fit his purposes. In the more specific industry of criminal law, defense attorneys are often criticized for advocating on behalf of defendants who are "obviously guilty," thus becoming roadblocks on the path to justice. Much to the contrary, however, defense attorneys provide a valuable serve that should earn them praise, not scorn. While it is true that every lawyer will do everything within his power to interpret the laws in the manner most beneficial to his client, such a characterization is by no means limited to defense attorneys. The prosecutor will do the same thing, employing all his legal knowledge and know-how to establish the guilt of the defendant. In this respect, the vague nature of the law is highlighted, and it becomes a virtual necessity for each side to use every tool at their disposal, on the assumption that the other side will also use every tool at his. The net result emerges as a positive, in which the tricks of the opposing attorneys cancel one another out, leaving only the truth, clearer and devoid of manipulation, presented for the jury's consideration. Further, the defense attorney is a vital element of the American judicial system, in that without him the defendant would stand no chance whatsoever. Under the constitution, even the most "obvious guilty" defendants are guaranteed the right to a fair trial, involving someone able and willing to advocate on his behalf. Of course, there are bad apples in the industry who are unethical and care nothing for actual justice, and whose only concerns are their wallets. Generally speaking, however, without defense attorneys, the system would crumble into a mere machine in which defendants are assumed guilty, without a chance to argue or prove otherwise, and many innocent people falsely charged with crimes would be severely punished for transgressions that they didn't commit. It is a basic fact that the adversarial system of justice in the United States is necessary in order to ensure the fairest and most unbiased presentation and evaluation of the facts possible. Without defense attorneys, that system cannot be carried out, and would result in a loss of the civil liberties that the nation enjoys and treasures. To that end, all of those who make that process a reality, including defense attorneys, deserve our support and admiration, not our suspicion and disdain.

单选题The remarkable progress of science and technology in the 20th century has brought enormous benefits to humankind. Long and healthy lives, economic prosperity and a pleasant and convenient living environment have resulted from technological progress based on advances in scientific knowledge. This progress will continue or may even accelerate in the future, because both the number of scientists and their activities are expanding throughout the world. We may expect, therefore, that science and technology will continue to contribute to the development of human society. At the same time, rapid scientific advances may raise some difficult problems. First of all, the disparity in scientific knowledge between those in scientific and technical professions and those in other areas will continuously expand. This may create a communications gap between the two groups that could affect obtaining public consent on important issues, such as the use of genetically engineered plants or human embryonic stem cells. Secondly, the 21st century will be characterized by a knowledge-based society and a knowledge of science will be required for many professions. Those who lack scientific knowledge will have fewer opportunities for good jobs. Thirdly, the enormous increase in scientific information will become a burden for children who must study science. Already young people seem to be losing interest in science, and this trend may increase in the future. Over the past several years, enrollment in high-school physics courses in Japan has been decreasing, which suggests that many young people are losing interest in physics or avoiding subjects that require diligent study. Finally, scientific research in the next century will require increasing levels of public investment because sophisticated research is usually expensive. If the public loses interest in, science or does not understand the importance of research, it will become difficult for scientists to obtain sufficient financial support. Because of these considerations, I think that we need to carefully review present science education at different levels and to improve it in order to meet the expected rapid progress of science in the 21st century. At the level of primary education, the' most important task is to stimulate children's interest in nature. Naive surprise at the wonders of nature will hopefully lead to a later interest in science. During their secondary education, students must learn logic and the principles of natural phenomena. They will gradually separate into groups of those who like and those who dislike science. It will be difficult to provide the latter students with the scientific basics that would be useful throughout their lives. This is also the case in university education. It is becoming a goal of general university education to give students who are not majoring in natural science and engineering some level of scientific literacy. In the future, all citizens, especially those expected to lead diverse areas of society should have a sound basis for understanding the progress of science. Because the pace of progress will accelerate further, continuing science education for the public is also of great importance.

单选题Every year thousands of people are arrested and taken to court for shop-lifting. In Britain alone, about HK $ 3,000,000"s worth of goods are stolen from shops every week. This amounts to something like HK $150 million a year, and represents about 4 percent of the shops" total stock. As a result of this "shrinkage" as the shops call it, the honest public has to pay higher prices. Shop-lifters can be divided into three main categories, the professionals, the deliberate amateur, and the people who just can"t help themselves. The professionals do not pose much of a problem for the store detectives, who, assisted by closed circuit television, two-way mirrors and various other technological devices, can usually cope with them. The professionals tend to go for high value goods in parts of the shops where security measures are tightest. And, in any case, they account for only a small percentage of the total losses due to shop-lifting. The same applies to the deliberate amateur who is, so to speak, a professional in training. Most of them get caught sooner or later, and they are dealt with severely by the courts. The real problem is the person who gives way to a sudden temptation and is in all other respects an honest and law-abiding citizen. Contrary to what one would expect, this kind of shop-lifter is rarely poor. He does steal not because he needs the goods and cannot afford to pay for them. He steals because he simply cannot stop himself. And there are countless others who, because of age, sickness or plain absent-mindedness, simply forget to pay for what they take from the shops. When caught, all are liable to prosecution and the decision whether to send for the police or not is in the hands of the store manager. In order to prevent the quite incredible growth in ship-lifting offences, some stores, in fact, are doing their best to separate the thieves from the confused by prohibiting customers from taking bags into the store. However, what is most worrying about the whole problem is, perhaps, that it is yet another instance of the innocent majority being penalized and inconvenienced because of the actions of a small minority. It is the aircraft hijack situation in another form. Because of the possibility of one passenger in a million boarding an aircraft with a weapon, the other 999,999 passengers must subject themselves to searches and delays. Unless the situation in the shops improves, in ten years" time we may all have to subject ourselves to a body-search every time we go into a store to buy a tin of beans!

单选题Why has the kiwi survived while its relatives the moas have become extinct? One reason, I think, is that it has adopted nocturnal(夜间活动的) habits. Kiwis are not normally about in the daytime. During the daylight hours they lie up in hiding, where enemies have no hope of finding them. Their coloration protects them; the strange drab(黄褐色的) feathering, so unlike that of most birds, gives them a cloak(伪装)of invisibility while they sleep. And when night falls, out they come to scratch in the ground and find worms and feed to their hearts' content. They couldn't do that so effectively if they didn't have another peculiarity that I have not mentioned yet. The nostrils(鼻孔) of most birds open high up near the base of the beak(猛禽的嘴), but the kiwi wears his nostrils right near the tip of the long bill. That's good for a bird that feeds in the ground at night. The kiwi's .sight is poor at the best of times, but his sense of smell is acute and so is the sense of touch in the tip of that long bill. He can scratch in the forest floor with his eyes closed, and the, delicate sense located at the beak, tip will feel the slightest movement of a worm(蠕虫). Most of those things have an odour(气味) of some kind, which the kiwi can smell better than we can. And when he either feels or smells something worthwhile in the way of food, the delicate bill is ready to pick it up and swallow it. You see, in spite of his primitiveness, he is peculiarly and efficiently equipped for the particular way of life — better equipped than any of his competitors — and so he is able to keep ahead of them, But every time we, fell a forest tree, or open wooded land for cultivation, we axe reducing the kiwi's chance of survival, because his undoubted talents axe useful to him only under special conditions, and if those conditions axe not maintained, out he goes like a candle.
