单选题{{B}}Passage One{{/B}} Researchers said it was clear that the world's oceans play a major role in queuing up rapid climate changes, but that thus far the mechanics (机制，结构) of such changes were poorly under stood. "It's like being blindfolded and walking toward the edge of a cliff," said Wallace Brocker, a professor of environmental sciences at Columbia University. "We don't understand (the factors) so we don't really know what to look for." Using ice cores drilled from glaciers and other ice sheets, the researchers have developed a model showing world temperatures' rising and falling with unsettling frequency over the past110 000 years. While some of the changes have been slow and steady, such as the end of the last Ice Age some 12 000 years ago, others have been swift and unexpected, such as the rapid warming of the North Atlantic from 1920 to 1930 and the Dust Bowl drought of the 1930s. The most drastic temperature changes—believed to be as much as 18 degrees Fahrenheit over the space of just a few years—exceed any recorded in human history, they said．This was not in tended to alarm the public, but that they hoped it would stimulate policy makers to prepare for the possibility of rapid temperature flux. Greenhouse gases, emitted by fossil fuels such as oil and coal, have been linked by many re searchers to a rise in global temperatures. A 1997 Kyoto Treaty on global warming sought to cut emissions of such gasses by developed nations, but the Bush administration this year spurned (轻蔑或傲慢地拒绝) the treaty, saying pollution controls would be too costly for the U.S. economy. The NAS panel called for research to identify what it described as "no-regrets" measures that would cost relatively little and would be good policies regardless of the extent of environmental change. Such measures could include regulations to reduce damage to water, air and land, or slow climate change, or helping societies cope with abrupt climate changes by developing new financial instruments such as weather derivatives (衍生证券) and catastrophe bonds to reflect the risks. Societies have faced both gradual and abrupt climate changes for millennial and have learned to adapt through various mechanisms, such as moving indoors, developing irrigation for crops, and migrating away from inhospitable (不适宜居住的) regions. It is important not to be fatalistic (宿命论的) about the threats posed by abrupt climate changes.

单选题 By 2010 the European Commission predicts transcontinental freight traffic will have risen 50 percent as a result of European expansion, and much of that will have to cross the enormous obstacle of the Alps. Right now the only practical way for most heavy traffic to get through is by truck and tunnel. And while that could change if safer and cleaner rail lines were opened, the chances are that won't happen anytime soon. Several private trucking companies have adapted quickly and creatively to the demands of European unification. Some of the bigger truckers trace cargoes with the Global Positioning System and sophisticated computers. And if trucks also bring more road hazards and pollution, at present there is no alternative. Right now only 8 percent of European merchandise moves by rail, compared with more than 40 percent in the United States. Delays are so common that the average speed for freight is about 18kin an hour. The railways have had trouble outgrowing a heritage of national rivalries and open warfare between Europe's countries. The result is what another European Commission report calls "a mosaic of badly interconnected national systems." Language barriers remain a problem, requiring crew changes at some borders. Switching systems and signals differ. And efficiency is more of a dream than a goal. Europe's railroads still have to deal with "phantom trains" that run so late that they combine with others and disappear from the railroad's records. In an era when many companies depend on a "just-in-time" inventories to make a profit, railroads are rarely on time at all. Yet there is little official enthusiasm for changing the system. The reality is that governments have helped create the imbalance between road and rail in Europe—and government action will likely be needed to fix it. The French emphasis on using rail to move people instead of goods, for instance, has helped cripple freight service. "All the investments went to passenger traffic," says Denis Douté, director of freight services for the French rail company SNCF. Freight trains have had to find "windows" to run in between passenger trains, unlike those in the United States, which often travel on separate tracks. The further development of the freight network requires massive investments to modernize existing infrastructure and open new ones. However, the political will to fund that kind of investment is lacking, which means the citizens will have to hold their noses for a while longer.

单选题At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don"t act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior. Perhaps the most interesting thing about the phenomenon of the behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as "On Death and Dying" and "Learning to Say Goodbye", people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject. One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It"s not taboo to talk about fat; it"s taboo to be fat. The "thin" look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self- respect. After all, people think, how can people who care about themselves, and therefore the way they look, permit themselves to become fat? In an image-conscious society like the U.S., thin is "in", fat is "out".
