单选题{{B}}Passage Five{{/B}} The Intergovernmental Panel on Climate Change concluded that global warming is no game. They provide evidence that heat-trapping gases related to human activities--such as carbon dioxide from burning coal, oil, and gas--are in part driving global warming by increasing the amount of the sun's heat trapped in the earth's atmosphere. This extra heat is making the global climate system unstable. Because the climate system is complex, scientists cannot predict precisely how much and how fast the climate will change. But sophisticated computer simulations project a range of scenarios for increases in average surface temperature between 1.8° and 6.3°F (1° and 3.5℃) by the year 2100. (Bear in mind that seemingly small changes in temperature can produce major changes in climate. During the last Ice Age, global temperatures were only 5° to 9°F cooler than they are today, but that was sufficient to bury what is now Canada, New York, and New England under a kilometer of ice.) Within the next 20 years, various regions of the world may experience severe changes in climate. Some may be vulnerable to longer droughts, others to more coastal flooding, and many to more frequent bouts of extreme weather. And if global warming continues unchecked, we could well see greater risk to human health as diseases previously found in tropical areas spread to higher latitudes and elevations. Also, insect-borne diseases such as malaria and dengue fever are already moving northward from tropical regions. Forests and wetlands provide critical benefits to human health, by filtering our air and water, and to human welfare, by providing opportunities for recreation and commerce. Changes in regional climate put many such ecosystems at risk by hindering their ability to grow and regenerate. The survival of these wetlands--often are as of high biodiversity that also provide protection against floods--depends on the water's temperature, flow, and level. Scientists are confident that global warming will reduce the area of wetlands and change their distribution. Arctic and subarctic wetlands, which are critical refuge and breeding grounds for large numbers of migratory species, are among the most vulnerable. Other coastal zone habitats--including marshes, mangroves, coral reefs and atolls, and river deltas--will also be threatened. Avoiding these costly damages justifies immediate action to turn off the road to ruin. Scientists and economists have identified many technically feasible, cost-effective opportunities for emissions reductions, including energy-efficiency measures, advanced vehicle technologies, cuts in oil and coal subsidies, and investments in clean, renew-able energy sources like wind and solar power. To take advantage of these opportunities, governments and industry must work together. The Union of Concerned Scientists (UCS) is working to advance policies that will turn our society aside from the ruinous road to a global warming future.

单选题To broaden their voting appeal in the Presidential election of 1796, the Federalists selected Thomas Pinckney, a leading South Carolinian, as running mate for the New Englander John Adams. But Pinckney's Southern friends chose to ignore their party's intentions and regarded Pinckney as a Presidential candidate, creating a political situation that Alexander Hamilton was determined to exploit. Hamilton had long been wary of Adams' stubbornly independent brand of politics and preferred to see his running mate, over whom he could exert more control, in the President's chair. The election was held under the system originally established by the Constitution. At that time there was but a single tally, with the candidate receiving the largest number of electoral votes declared President and the candidate with the second largest number declared Vice President. Hamilton anticipated that all the Federalists in the North would vote for Adams and Pinckney equally in an attempt to ensure that Jefferson would not be either first or second in the voting. Pinckney would be solidly supported in the South while Adams would not. Hamilton concluded if it were possible to divert a few electoral votes from Adams to Pinckney, Pinckney would receive more than Adams, yet both Federalists would outpoll Jefferson. Various methods were used to persuade the electors to vote as Hamilton wished. In the press, anonymous articles were published attacking Adams for his monarchial tendencies and Jefferson for being overly democratic, while pushing Pinckney as the only suitable candidate. In private correspondence with state party leaders the Hamiltonians encouraged the idea that Adams' popularity was slipping, that he could not win the election, and that the Federalists could defeat Jefferson only by supporting Pinckney. Had sectional pride and loyalty not run as high in New England as in the deep South, Pinckney might well have become Washington's successor. New Englanders, however, realized that equal votes for Adams and Pinckney in their states would defeat Adams; therefore, eighteen electors scratched Pinckney's name from their ballots and deliberately threw away their second votes to men who were not even running. It was fortunate for Adams that they did, for the electors from South Carolina completely abandoned him, giving eight votes to Pinckney and eight to Jefferson. In the end, Hamilton's interference in Pinckney's candidacy lost even the Vice-Presidency of South Carolina. Without New England's support, Pinckney received only 59 electoral votes, finishing third to Adams and Jefferson. He might have been President in 1797, or as Vice President a serious contender for the Presidency in 1800; instead, stigmatized by a plot he had not devised, he served a brief term in the United States Senate and then dropped from sight as a national influence.

单选题Public speaking fills most people with dread. Humiliation is the greatest fear; self- exposure and failing to appeal to the audience come a close second. Women hate it most, since girls are pressurized from an early age to be concerned with appearances of all kinds. Most people have plenty of insecurities, and this seems like a situation that will bring them out. If you were under pressure to be perfect, you are terrified of falling in the most public of ways. Extroverts, on the contrary, will feel less fear before the ordeal. It does not mean they will necessarily do it better. Some very shy people manage to shine. When I met the British comedian Julian Clary, he was shy and cautious, yet his TV performances are perfect. In fact, personality is not the best predictor of who does it well. Regardless of what you are like in real life, the key seems to be to act yourself. Actual acting, as in performing the scripted lines of a character other than yourself, does not do the job. While politicians may limit damage by having carefully rehearsed, written scripts to speak from, there is always a hidden awareness among the audience that the words might not be true. Likewise, the incredibly perfect speeches of many American academics are far from natural. You may end up buying their book on the way out, but soon afterwards, it is much like fast food, and you get a nameless sense that you"ve been cheated. Although, as Earl Spencer proved at his sister Princess Diana"s funeral, it is possible both to prepare every word and to act naturally. A script rarely works and it is used to help most speakers. But, being yourself doesn"t work either. If you spoke as if you were in your own kitchen, it would be too authentic, too unaware of the need to communicate with an audience. I remember going to see British psychiatrist R. D. Laing speak in public. He behaved like a seriously odd person, talking off the top of his head. Although he was talking about madness and he wrote on mental illness, he seemed to be exhibiting rather than explaining it. The best psychological place from which to speak is an unselfconscious self- consciousness, providing the illusion of being natural. Studies suggest that this state of "flow", as psychologists call it, is very satisfying.

单选题Our culture has caused most Americans to assume not only that our language is universal but that the gestures we use are understood by everyone. We do not realize that waving goodbye is the way to summon a person from the Philippines to one's side, or that in Italy and some Latin-American countries, curling the finger to oneself is a sign of farewell. Those private citizens who sent packages to our troops occupying Germany after World War II and marked them GIFT to escape duty payments did not bother to find out that " Gift" means poison in German. Moreover, we like to think of ourselves as friendly, yet we prefer to be at least 3 feet or an arm 's length away from others. Latins and Middle Easterners like to come closer and touch, which makes Americans uncomfortable. Our linguistic and cultural blindness and the casualness with which we take notice of the developed tastes, gestures, customs and languages of other countries, are losing us friends, business and respect in the world. Even here in the United States, we make few concessions to the needs of foreign visitors. There are no information signs in four languages on our public buildings or monuments; we do not have multilingual guided tours. Very few restaurant menus have translations, and multilingual waiters, bank clerks and policemen are rare. Our transportation systems have maps in English only and often we ourselves have difficulty understanding them. When we go abroad, we tend to cluster in hotels and restaurants where English is spoken. Then attitudes and information we pick up are conditioned by those natives — usually the richer — who speak English. Our business dealings, as well as the nation's diplomacy, are conducted through interpreters. For many years, America and Americans could get by with cultural blindness and linguistic ignorance. After all America is the most powerful country of the free world, the distributor needed funds and goods. But all that is past. American dollars no longer buy all good things, and we are slowly beginning to realize that our proper role in the world is changing. A 1979 Harris poll reported that 55 percent of Americans want this country to play a more significant role in world affairs; we want to have a hand in the important decisions of the next century, even though it may not always be the upper hand.

单选题A black hole is an astronomical body A whose gravity is so strong that nothing can escape from it. It was Newton B who first stated that light C is composed of particles. The French mathematician De Laplace next reasoned that if enough mass D was added to a star like the sun, the gravitational force of the star would eventually prevent light particles from leaving it; it would therefore "blink out" and become an invisible black star.

单选题 The concept of biodiversity encompasses several different levels of biological organization, from the very specific to the most general. It has been clear for some time that at all of these levels of organization the rich biodiversity that has always characterized the natural world is today declining. The extinctions or threatened extinctions of many species are but the most visible and well- known manifestation of a deeper and more far-reaching trend. Changes in how the land is used are probably the principal contributor to the current decline in biodiversity. The pressures on terrestrial resources and land depend very much on population growth and the demands of early stages of economic development. Moreover, land acquisition, especially. for agriculture and forestry, focuses initially on those areas with the most fertile soils and equable climates, which are often the areas of greatest biological diversity. Deforestation in the humid tropics is probably the best-known current example of rapid land-use change. During the decade of the 1970s, vast areas of tropical forest in South America, Africa, and South-east Asia were cleared and converted to agriculture and other uses. In the middle-to-late 1980s, the rates of deforestation in South America slowed dramatically, largely due to economic and tax policy changes in Brazil, but the pace of cutting in Africa and Southeast Asia, though poorly quantified, remains high. Globally, the rate of loss of tropical forests for the 1980s has been estimated at about I percent per year, but there is still considerable uncertainty. The rates of extinction of local species that accompany these rapid changes in land cover may soon be far in excess of what is found today, reaching as high as 10, 000 times the natural background rate. Analyses of potential impacts on biodiversity that are based on simple measures of deforested area can provide little more than very general conclusions. Heavy applications of fertilizers and pesticides have the potential of creating additional environmental problems as well as affecting the abundance and viability of the other plants and animals and micro-organisms in the same or adjoining areas. In addition, because of the understandable tendency to put the best land into production first, the expansion of agriculture into less fertile areas typically requires heavier applications of chemicals, more extensive site preparation, and other forms of more intensive management. The typical result is increased chemical runoff to the landscape, and with ensuing degradation, additional pressure for expansion, and the like. It is such a cycle that has led to widespread desertification in some parts of the world, primarily through overgrazing that can be compounded by naturally occurring droughts.
