单选题{{B}}Questions 16-20 are based on the following passage:{{/B}} We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways. It is tree that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns. Fear is another emotion that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like "he went pale and begin to tremble" suggests that the man is either very afraid or he has just got a very big shock. However, "he opened his eyes wide" is used to suggest anger in Chinese whereas in English it means surprise. In Chinese surprise can be described in a phrase like "they stretched out their tongues!" Sticking out your tongue in English is an insulting gesture or expresses strong dislike. Even in the same culture, people differ in ability to understand and express feelings. Experiments in the United States have shown that women are usually better than men at recognizing fear, anger, love and happiness on people's faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do.

单选题 Why does cream go bad faster than butter? Some researchers think they find the answer,and it comes down to the structure of the food, not its chemical eomposition--a finding that couldhelp rid some processed foods of chemical preservatives. Cream and butter contain pretty much the same substances, so why cream should sour muchfaster has been a mystery. Both are emulsions--tiny globules(小球)of one liquid evenly distributedthroughout another. "The difference lies in what's in the globules and what's in the surroundingliquid", says Brocklehurst, who led the investigation. In cream, fatty globules drift about in asea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteriawhich make the food go bad prefer to live in the watery regions of the mixture. "This means that incream, the bacteria are free to grow throughout the mixture", he says. When the situation is reversed, the bacteria are locked away in compartments (密封的)buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidlyrun out of nutrients. They also slowly poison themselves with their waste products. "In butter, youget a self-limiting system which stops the bacteria growing", says Brocklehurst. The researchersare already working with food companies keen to see if their products can be made resistant tobacterial attack through alterations to the food' s structure. Brocklehurst believes it will be possibleto make the emulsions used in salad cream, for instance, more like that in butter. The key will beto do this while keeping the salad cream liquid and not turning it into a solid lump.

单选题The decline in moral standards—which has long concerned social analysts—has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad. The fact the ordinary citizens are now starting to think seriously about the nation"s moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it. But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. "The thought that "I"m in it for me" has become deeply rooted in the national consciousness," Ms. Elshtain says. Some of this can be attributed to the disintegration of traditional communities, in which neighbors looked out for one another, she says. With today"s greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on self. In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the U.S. and Elshtain says the public is correct to sense that; Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers. The desire for a higher moral standard is not a lament (挽歌) for some nonexistent "golden age," Elshtain says, nor is it a wishful (一厢情愿的) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor the lessening of prejudice. Moral decline will not be reversed until people find ways to counter the materialism in society, she says. "Slowly, you recognize that the things that matter are those that can"t be bought. " (293 words)

单选题Esperanto is an artificial language designed to serve internationally as an secondary means of communication among speakers of different languages. The creation of Ludovic Lazar Zamenhof, a Polish-Jewish ophthalmologist(眼科学者), Esperanto was first presented in 1887. An international movement to promote its use, although originally annoyed with 'disagreement, has continued to flourish and has members in more than 80 countries. Esperanto is used internationally across language boundaries by at least one million people, particularly in specialized fields. It is used in personal contacts, on radio broadcasts, and in a number of publications of both modern works and classics. Its popularity has spread from Europe— both East and West — to such countries as Brazil and Japan. It is, however, in China that Esperanto had had its greatest impact. It is taught in universities and used in many translations (often in scientific or technological works). El Popola Cinio (From People's China), a monthly magazine in Esperanto, is read worldwide. Radio Beijing's Esperanto program is the most popular program in Esperanto in the world. Esperanto's vocabulary is drawn primarily from Latin, the Romance languages, English, and German. Spelling is completely regular. A simple and consistent set of endings indicates grammatical functions of words. Thus, for example, every noun ends in o, every adjective in a, and the infinitive(不定式) of every verb in i. Esperanto also has a highly productive system of constructing new words from old: ami, to love; malami, to hate; malameno, the tendency to hate.

单选题Passage Three It remains to be seen whether the reserves of raw materials in the year 2000 will be sufficient to supply a world economy which will have grown by five hundred percent. Southeast Asia alone will have an energy consumption five times greater than that of Western Europe in 1970. Incidentally, if the underdeveloped countries started using up petrol at the same rate as the industrialized areas, then world reserves would be exhausted by 1990. All this only goes to show just how important it is to set up a plan to conserve and divide up fairly natural resources on a worldwide scale. This is a matter of life and death because world population is expanding at an incredible rate. By the middle of the next century population will expand every year by as much as it did in the first 1,500 years after Christ. In the southern, poor parts of the globe, the figures are enough to make your hair stand on end. Even supposing that steps are taken to stabilize world population in the next fifty years, the number of inhabitants per square kilometer will increase by from 4 in the United States to 140 in South East Asia. What can we do about it? In the first hypothesis we do nothing. By the year 2000, the southern parts of the world would then have a population greater than the total world population today. Alternately we could start acting right now to bring birth rate under control within fifteen years so that population levels off. Even then the population in the southern areas would not stop growing for seventy-five years. And the population would level off at something like twice today's figure. Finally, we could wait ten to twenty years before taking action. If we wait ten years the population of the southern area would stabilize at 3,000 million. Even today the number of potential workers increases by 350,000 people per week. By the end of the century this figure will reach 750,000; in other words, it will be necessary to find work for 40 million people per year--not to speak of food. What this means in practical terms we can scarcely imagine. But clearly if we do nothing, nature will solve the problem for us. But at what cost!

单选题Now, our biggest summertime question has been answered: Why do people look so much better in sunglasses? Vanessa Brown, a senior lecturer of art and design at Nottingham Trent University, gave an inside look into the connection between shades and sex appeal. According to Brown, sunglasses do a wide variety of positive things. They make up for any asymmetries (不对称), which relates directly to research proving that symmetrical {aces are the most attractive ones. If you put on a pair of sunglasses, the lenses will instantly create a perfectly symmetrical face. Sunglasses also create the appearance of a defined bone structure on top of a relatively softer face. Additionally, people often form quick judgments about others by looking into their eyes. Through eye contact, we can determine someone"s confidence, sincerity and intelligence. If those eyes are shielded, though, a person is automatically unreadable. We take them for granted today, but sunglasses are a relatively modern everyday accessory (饰件). Sales started to pick up in the 1920s, but they didn"t become commonplace until about two decades after that. In their early days sunglasses were primarily used during risky water and snow sports, and were also associated with new technologies like airplane travel, which made them seem "daring and thoroughly modern." Later, Hollywood stars of the 1950s and 1960s started wearing sunglasses to defend themselves from being recognized by the public or harassed by paparazzi (狗仔队). Movie stars" adoption of the accessory strengthened the link between sunglasses and appeal.

单选题{{B}}Passage Two{{/B}} Global energy demand is expected to triple by mid-century. The earth is unlikely to run out of fossil fuels by then, given its vast reserves of coal, but it seems unthinkable that we will continue to use them as we do now. It's not just a question of supply and price, or even of the disease caused by filthy air. The terrorist assault on the World Trade Center raises other scary scenarios: how much easier would it be to crack open the Trans-Alaska pipeline and how much deadlier would it be to bomb a nuclear plant than to attack a wind arm? Skeptics may recall the burst of enthusiasm for conservation and renewable power when oil prices quadrupled in the 1970s. State-funded energy research and development surged, while tax incentives boosted solar, wind and other alternatives to petroleum and the atom. But when oil supplies loosened and prices dropped in the early 1990s, governments lost interest. In the state of California, subsidies evaporated, pushing wind companies into bankruptcy. Clean energy has long way to go. Only 2.2% of the world's energy comes from "new" renewables such as small hydroelectric dams, wind, solar and geothermal. How to boost that share--and at what pace--is debated in industrialized nations--from Japan, which imports 99.7 % of its oil, to Germany, where the nearby Chernobyl accident turned the public against nuclear plants, to the U.S., where the Bush Administration has strong ties to the oil industry. But the momentum toward clean renewables is undeniable. How soon we reach an era of clean, inexhaustible energy depends on technology. Solar and wind energies are intermittent: When the sky is cloudy or the breeze dies down, fossil fuel or nuclear plants must kick into compensate. But scientists are working on better ways to store electricity from renewable sources. While developed nations debate how to fuel their power plants, however, some 1.6 billion people--a quarter of the globe's population--have no access to electricity or gasoline. Many spend their days collecting firewood and cow dung, burning it in primitive stoves that belch smoke into their lungs. To emerge from poverty, they need modern energy. And renewables can help. From village-scale hydropower to household photovoltaic systems to bio-gas stoves that convert dung into fuel. Ultimately, the earth can meet its energy needs without fouling the environment. "But it won't happen," asserts Thomas Johansson, an energy adviser to the United Nations Development Program, "without political will." To begin with, widespread government subsidies for fossil fuels and nuclear energy must be dismantled to level the playing field for renewables. Moreover, government should pressure utility to meet targets for renewable sources of energy.
