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 (矾土) 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, and 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Americans are pound of their variety and individuality, yet they love and respect few things more than a uniform, whether it is; the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States? Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity (身 份) than to step out of uniform? Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible (可减税的). They are often more comfortable and more durable than civilian clothes. Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least. Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes. (294 words)

单选题According to a survey, which was based on the responses of over 188,000 students, today's traditional-age college freshmen are "more materialistic and less altruistic(利他主义的)"than at any time in the 17 years of the poll. Not surprising in these hard times, the student's major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life". It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the "altruistic" fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job--even before she completed her two-year associate degree. While it's true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions--be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; no j0b. How shortsighted in the long run! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish right from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题 Languages are remarkably complex and wonderfully complicated organs of culture. They contain the quickest and the most efficient means of communicating within their respective culture. To learn a foreign language is to learn another culture. In the words of a poet and philosopher, "As many languages as one speaks, so many lives one lives. " A culture and its language are as necessary as brain and body; while one is a part of the oth- er, neither can function without the other. In learning a foreign language, the best begin- ning would be starting with the non-language elements of the language: its gestures, its body language, etc. Eye contact is extremely important in English. Direct eye contact leads to understanding, or, as the English saying goes, seeing eye-to-eye. We can never see eye-to-eye with a native speaker of English until we have learned to look directly into his eyes.

单选题Text 3 It's wonderful how everyone agrees (or fears to disagree) that genetic discrimination is a bad thing. Your genes are beyond your control. Why should you be punished for them? Unfortunately, genetic discrimination is universal, inevitable and, in some ways, essential. Leaving aside the hot issue of intelligence, consider clearly genetic traits such as musical or athletic talent. Practice, practice will get you to Carnegie Hall, but only if you're born on the right bus. The notion of not discriminating on the basis of inborn talent is not even an abstract ideal, the world would be a poorer place if it did not distinguish between me and Yo-Yo Ma in doling out opportunities to be a concert cellist. As we learn more about the human genome, we'll learn that more and more of the traits we reward have a genetic component. Martin Luther King said we should all be judged on "the content of our character." But if a disposition to hard work or courage or creative imagination turns out to have a large genetic component, should we still judge people based on these qualities? Then, too, the world discriminates on the basis of clearly genetic traits, such as physical beauty, that are irrelevant in most circumstances. Occasionally, some zealot proposes to ban this kind of discrimination, too. But it will never happen. So what is the limiting principle on banning genetic discrimination? Where do we stop? Right now, the universal consensus makes a distinction between the results of genetic tests and genetic traits that reveal themselves in some other way. It seems unfair and arbitrary that your fate in life should be determined in any important way by what a drop of your blood reveals under a microscope; but logically, there is no difference between this and letting your fate be determined by how tall or musically gifted you are. A Juilliard tryout is, in part, a genetic test. If there were a blood test for musical talent, as there may be some day, it would do the same thing more efficiently. A blood test might even be fairer than the crude substitutes we use instead to judge and choose among people: It would zero in on the trait we really need to discriminate about and reduce discrimination on the basis of traits that are irrelevant. Some people say the danger is that genetic testing will encourage irrelevant discrimination; employers will overreact and refuse to hire you even though your actual likelihood of getting Alzheimer's before your retirement is minuscule. But discriminationby mistake will often bring its own punishment, like any business misjudgment. The real problem is discrimination that makes perfect sense. A health insurer is not crazy or stupid to want to keep people out of its insurance pool if they're more likely to get sick. Nor is the company evil to do this if the law allows it. The idea of insurance is to protect against unpredictable costs. Ignoring predictable costs, when your competitors aren't required to do the same, is a recipe for bankruptcy.

单选题 Sporting activities are essentially modified forms of hunting behavior. Viewed biologically, the modem foot-bailer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey (猎物) into a goalmouth. If his aim is accurate and he scores a goal, he enjoys the hunter's triumph of killing his prey. To understand how this transformation has taken place we must briefly look back at our forefathers. They spent over a million years evolving as cooperative hunters. Their very survival depended on success in the hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They cooperated as skillful male-group attackers. Then about ten thousand years ago, after this immensely long period of hunting their food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use--that of controlling and domesticating their prey. The hunt became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunt were no longer essential for survival.
