单选题{{B}}Passage Four{{/B}} In science the meaning of the word "explain" suffers with civilization's every step in search of reality. Science can not really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modem scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul's Cathedral; it is a way in which things behave." When we have told how things behave when they are electrified, we have told all there is to tell. Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of 'reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can conclude that objects fall to the ground because that is where they belong, and smoking goes up because that is where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation.

单选题Imagine asking a presidential candidate to sit down for a sensitivity session on gay and lesbian issues. That's exactly what we did last week in Austin, Texas. George W. Bush invited us, a dozen gay Republicans, after he'd refused to meet with a gay Republican group that had criticized him. Our meeting set an important precedent: never again will a major-party candidate be able to run for president without addressing gay and lesbian issues. Bush didn't like everything we had to say. I was struck by his lack of familiarity with the issues, as well as by his desire to learn. I described how my partner, Rob Morris, and I have been in a 17-year relationship. We both come from healthy, strong, religious families. Rob grew up in a conservative Republican family in Georgia; I come from a longtime Republican family in Wisconsin. I'm now the vice president of my Lutheran church. I wanted Governor Bush to understand that long-term, loving relationships, stable families, strong faith-based traditions and Republican voting histories are all part of the gay and lesbian community. Our stories had an impact. Bush admitted that, growing up in Texas, he had not been as open to elements of America's diverse culture. He had a narrow set of friends and a firm set of traditions. But he was surprised and dismayed to hear that people saw him as intolerant. " What have I said that sent that signal?" he asked repeatedly. We confronted him about his reported statement that if you were openly gay or lesbian you would not be considered for a job in his administration. "I never said that," he insisted, assuring us he would hire gays and lesbians who both were qualified and shared his political views. Our perspective was clearly eye-opening to him. When one of us talked about his lesbian sister and her partner adopting children, the governor acknowledged his often-stated belief that gays should not adopt. "Now you're telling me of a very loving, caring relationship," he said. "I really appreciate hearing that. " We stressed that a Bush administration could not roll back any of the progress made in recent years. We talked about AIDS funding and research. Though Bush was attentive — and does show a willingness to hear all sides — I don't think we changed his positions. He still opposes gay marriage and classifying crimes against gays as hate crimes. To be honest, Bush still has a long way to go. But I think he's a lot farther along today than he was last week.

单选题 At the Kyoto conference on global warming in December 1997, it became abundantly clear how complex it has become to work out international agreements relating to the environment be- cause of economic concerns unique to each country. It is no longer enough to try to forbid certain activities or to reduce emissions of certain substances. The global challenges of the interlink between the environment and development caressingly bring us to the core of the economic life of the states. During deep cuts in emissions harmful to the ozone layer, these reductions were made possible because substitutions had been found for many of the harmful chemicals and, more important, because the harmful substances could be replaced without negative effects on employment and the economies of states. Although the threat of global warming has been known to the world for decades and all countries and leaders agree that we need to deal with the problem, we also know that the effects of measures, especially harsh measures taken in some countries, would be nullified if other countries do not control their emissions. Whereas the UN team calls on the emissions to be cut globally by 60% to stabilize the content of CO2 in the atmosphere, this path is not feasible for several reasons. Such deep cuts would cause a breakdown of the world economy. Important and populous low- or medium-income countries are not yet willing to undertake legal commitments about their energy uses. In addition, the state of world technology would not yet permit us to make such a big leap. We must, however, find a solution to the threat of global warming early in the 21st century. Such a commitment would require a degree of shared vision and common responsibilities new to humanity. Success lies in the force of imaginations, in imagining what would happen if we fail to act. Although many living in cold regions would welcome the global warming effect of a warmer summer, few would cheer the arrival of the subsequent tropical diseases, especially where there had been one.

单选题{{B}}Passage Two{{/B}} Climatic conditions are delicately adjusted to the composition of the Earth's atmosphere. If there were a change in the atmosphere for example, in the relative proportions of atmosphere gases the climate would probably change also. A slight increase in water vapor, for instance, would increase the heat-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the amount of solar energy reaching the Earth's surface. The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth's incoming energy is short wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the received energy as a long wavelength radiation, which CO2 absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by the Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2 concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2 concentration would lead only to a reduction in global temperatures of 3℃. If, because of an increase in forest fires or volcanic activities, the CO2 content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of CO2, would probably increase. As a consequence, plants would use more and more CO2. Eventually CO2 levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2 would thereby be returned to the atmosphere and gradually the temperatures would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2 present in the atmosphere, with regular temperature increases and decreases of a set magnitude. Some climatologists argue that the burning of fossil fuels has raised the level of CO2 in the atmosphere and has caused a global temperature rise of at least 1℃. But a supposed global temperature rise of 1℃ may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and caused simply by shifts in the pattern of atmospheric circulation. Other areas, for example, the Southern Hemisphere oceanic zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.

单选题{{B}}Part A{{/B}}There are three 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 the corresponding letter on the Answer Sheet with a single line through the center. In 1998 consumers could purchase virtually anything over the Internet. Books, compact discs, and even stocks were available from World Wide Web sites that seemed to spring up almost dally. A few years earlier, some people had predicted that consumers accustomed to shopping in stores would be reluctant to buy things that they could not see or touch in person. For a growing number of time-starved consumers, however, shopping from their home computer was proved to be a convenient alternative to driving to the store. A research estimated that in 1998 US consumers would purchase $ 7.3 billion of goods over the Internet, double the 1997 total. Finding a bargain was getting easier owing to the rise of online auctions and Web sites that did comparison shopping on the Internet for the best deal. For all the consumer interest, retailing in cyberspace was still a largely unprofitable business, however. Internet pioneer Amazon. com, which began selling books in 1995 and liter branched into recorded music and videos, posted revenue of $ 153.7 million in the third quarter, up from $ 37.9 million in the same period of 1997. Overall, however, the company's loss widened to $ 45.2 million from $ 9.6 million, and analysis did not expect the company to turn a profit until 2001. Despite the great loss, Amazon. com had a stock market value of many billions, reflecting investors' optimism about the future of the industry Internet retailing appealed to investors because it provided an efficient means for reaching millions of consumers without having the cost of operating conventional stores with their armies of salespeople. Selling online carried its own risks, however. With so many companies competing for consumers' attention, price competition was intense and profit margins thin or nonexistent. one video retailer sold the hit movie Titanic for $ 9. 99, undercutting (削价) the $ 19.99 suggested retail price and losing about $ 6 on each copy sold. With Internet retailing still in its initial stage, companies seemed willing to absorb such losses in an attempt to establish a dominant market position.
