单选题(84) Flying over a desert area in an airplane, two scientists looked down with their trained eyes at trees and bushes. After an hour"s flight one of the scientists wrote in his book, "Look here for probable metals." Scientists in another airplane, flying over a mountain region, sent a message to other scientists on the ground, "Gold possible." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word, "Uranium." None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth"s surface. They were merely putting to use one of the newest methods of locating minerals in the ground—using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. (85) This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of trees and bushes that grow on the surface. At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees, and roots were dug out and put into boxes with each bag and box carefully marked. In a scientific laboratory, the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing "on the ends of the branches. If the trees had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging deeper. They did dig and found more gold below. When they dug deeper, they found large quantities of gold.

单选题Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world"s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn"t have to be the outcome. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all used except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.

单选题1One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. He was standing at the edge of one of the tanks where several of these highly intelligent, friendly creatures were kept. Elvar had just swum up alongside him and had turned on his back. He wanted Sagan to scratch his stom ach again, as the astronomer had done twice before. But this time Elvar was too deep in the water for Sagan to reach him. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water into the air and made a sound just like the word "More!" The astonished astronomer went to the director of the institute and told him about the incident. "Oh, yes. That's one of the words he knows," the director said, showing no surprise at all. Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of dan ger. Sound travels much faster and much further in water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a "language" in the real sense of the word? Scientists don't agree on this. A language is not just a collection of sounds, or even words. A language has a struc ture, or what we call a grammar. The grammar of a language helps to give it meaning. For example, the two questions "Who loves Mary?" and "Who does Mary love?" mean dif ferent things. If you stop to think about it, you will see that this difference doesn't come from the words in the question but from the difference in structure. That is why the ques tion "Can dolphins speak?" can't be answered until we find out if dolphins not only make sounds but also arrange them in ways which affect their meaning.

单选题Before whenever we had wealth, we started discussing poverty. Why not now? Why is the current politics of wealth and poverty seemingly about wealth alone? Eight years ago, when Bill Clinton first ran for president, the Dow Jones average was under 3,500, yearly federal budget deficits were projected at hundreds of billions of dollars forever and beyond, and no one talked about the "permanent boom" or the "new economy". Yet in that more straitened time, Clinton made much of the importance of "not leaving a single person behind". It is possible that similar "compassionate" rhetoric might yet play a role in the general election. But it is striking how much less talk there is about the poor than there was eight years ago, when the country was economically uncertain, or in previous eras, when the country felt flush . Even last summer, when Clinton spent several days on a remarkable, Bobby Kennedy-like pilgrimage through impoverished areas from Indian reservations in South Dakota to ghetto neighborhoods in East St. Louis, the administration decided to refer to the effort not as a poverty tour but as a "new markets initiative". What is happening is partly a logical, policy-driven reaction. Poverty really is lower than it has been in decades, especially for minority groups. The most attractive solution to it—a growing economy—is being applied. The people who have been totally left out of this boom often have medical, mental or other problems for which no one has an immediate solution, "The economy has sucked in anyone who has any preparation, any ability to cope with modem life." Says Franklin D. Raines, the former director of the Office of Management and Budget who is now head of Fannie Mae. When he and other people who specialize in the issue talk about solutions, they talk analytically and long-term: education. Development of work skills, shifts in the labor market, adjustments in welfare reform. But I think there is another force that has made this a rich era with barely visible poor people. It is the unusual social and imaginative separation between prosperous America and those still left out... It"s simple invisibility, because of increasing geographic, occupational, and social barriers that block one group from the other"s view.

You're in a restaurant, and the waiter has his pen at the ready. As you hesitate, he gradually begins to take a close interest in the ceiling, his fingernails, then in your dining partner. Each dish on the menu becomes a blur as you roll your eyes up and down in a growing panic. Finally, you desperately opt for something that turns out to be what you hate. It seems that we need devices to protect us from our hopelessness at deciding between 57 barely differentiated varieties of stuff-be they TV channels, gourmet coffee, downloadable ring tones, or perhaps, ultimately even interchangeable lovers. This thought is opposed to our government's philosophy, which suggests that greater choice over railways, electricity suppliers and education will make us happy. In my experience, they do anything but. Perhaps the happiest people are those who do not have much choice and aren't confronted by the misery of endless choice. True, that misery may not be obvious to people who don't have a variety of luxuries. If you live in Madagascar, say, where average life expectancy is below 40 and they don't have digital TV or Starbucks, you might not be impressed by the anxiety and perpetual stress our decision - making paralysis causes. Choice wasn't supposed to make people miserable. It was supposed to be the hallmark of self-determination that we so cherish in capitalist western society. But it obviously isn't: ever more choice increases the feeling of missed opportunities, and this leads to self-blame when choices fail to meet expectations. What is to be done? A new book by an American social scientist, Barry Schwartz, called {{I}}The Paradox of Choice{{/I}}, suggests that reducing choices can limit anxiety. Schwartz offers a self-help guide to good decision making that helps us to limit our choices to a manageable number, and ultimately derive greater satisfaction from the choices we make. This is a capitalist response to a capitalist problem. But once you realize that your Schwartzian filters are depriving you of something you might have found enjoyable, you will experience the same anxiety as before, worrying that you made the wrong decision in drawing up your choice-limiting filters. Arguably, we will always be doomed to buyers-remorse and the misery it entails. The problem of choice is perhaps more difficult than Schwartz allows.
