Then imagine dust storms sweeping up toxic pesticides and chemical fertilizers from the dry seabed and spewing them across towns and villages。 　　Seem like a scene from a movie about the end of the world? For people living near the Aral Sea in Central Asia, it’s all too real. Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate(provide water for)farmland. As a result, the sea has shrunk to half its original size, stranding ships on dry land. The seawater has tripled in salt content and become polluted, killing all 24 native species of fish。 　　Similar large-scale efforts to redirect water in other parts of the world have also ended in ecological crisis, according to numerous environmental groups. But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. Why? People in many parts of the world are desperate for water, and more people will need more water in the next century。 　　“Growing populations will worsen problems with water,” says Peter H. Gleick, an environmental scientist at the Pacific Institute for studies in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as onethird of the world’s projected 8.3 billion people will suffer from water shortages。 　　Where Water Goes 　　Only 2.5 percent of all water on Earth is freshwater, water suitable for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Twothirds of this freshwater is locked in glaciers and ice caps. In fact, only a tiny percentage of freshwater is part of the water cycle, in which water evaporates and rises into the atmosphere, then condenses and falls back to Earth as precipitation(rain or snow)。 　　Some precipitation runs off land to lakes and oceans, and some becomes groundwater, water that seeps into the earth. Much of this renewable freshwater ends up in remote places like the Amazon river basin in Brazil, where few people live. In fact, the world’s population has access to only 12,500 cubic kilometers of freshwater—about the amount of water in Lake Superior. And people use half of this amount already. “If water demand continues to climb rapidly,” says Postel, “there will be severe shortages and damage to the aquatic environment。” 　　Close to Home 　　Water woes may seem remote to people living in rich countries like the United States. But Americans could face serious water shortages, too especially in areas that rely on groundwater. Groundwater accumulates in aquifers, layers of sand and gravel that lie between soil and bedrock. (For every liter of surface water, more than 90 liters are hidden underground。)Although the United States has large aquifers, farmers, ranchers, and cities are tapping many of them for water faster than nature can replenish it. In northwest Texas, for example, over pumping has shrunk groundwater supplies by 25 percent, according to Postel。 　　Americans may face even more urgent problems from pollution. Drinking water in the United States is generally safe and meets high standards. Nevertheless, one in five Americans every day unknowingly drinks tap water contaminated with bacteria and chemical wastes, according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell ill in 1993 after drinking tap water tainted with cryptosporidium, a microbe that causes fever, diarrhea and vomiting。 　　The Source 　　Where do contaminants come from? In developing countries, people dump raw sewage into the same streams and rivers from which they draw water for drinking and cooking; about 250 million people a year get sick from water borne diseases。 　　In developed countries, manufacturers use 100,000 chemical compounds to make a wide range of products. Toxic chemicals pollute water when released untreated into rivers and lakes. (Certain compounds, such as polychlorinated biphenyls, or PCBs, have been banned in the United States。) 　　But almost everyone contributes to water pollution. People often pour household cleaners, car antifreeze, and paint thinners down the drain; all of these contain hazardous chemicals. Scientists studying water in the San Francisco Bay reported in 1996 that 70 percent of the pollutants could be traced to household waste。 　　Farmers have been criticized for overusing herbicides and pesticides, chemicals that kill weeds and insects but that pollute water as well. Farmers also use nitrates, nitrogen-rich fertilizer that help plants grow but that can wreak havoc on the environment. Nitrates are swept away by surface runoff to lakes and seas. Too many nitrates “over enrich” these bodies of water, encouraging the buildup of algae, or microscopic plants that live on the surface of the water. Algae deprive the water of oxygen that fish need to survive, at times choking off life in an entire body of water。 　　What’s the Solution? 　　Water expert Gleick advocates conservation and local solutions to water-related problems; governments, for instance, would be better off building small-scale dams rather than huge and disruptive projects like the one that ruined the Aral Sea。 　　“More than 1 billion people worldwide don’t have access to basic clean drinking water,” says Gleick。“There has to be a strong push on the part of everyone—governments and ordinary people—to make sure we have a resource so fundamental to life。” 　　1. That the huge water projects have diverted the rivers causes the Aral Sea to shrink。 　　2. The construction of massive dams and irrigation projects does more good than harm。 　　3. The chief causes of water shortage are population growth and water pollution。 　　4. The problems Americans face concerning water are groundwater shrinkage and tap water pollution。 　　5. According to the passage all water pollutants come from household waste。 　　6. The people living in the United States will not be faced with water shortages。 　　7. Water expert Gleick has come up with the best solution to water-related problems。 　　1.［Y］［N］［NG］2.［Y］［N］［NG］3.［Y］［N］［NG］4.［Y］［N］［NG］ 　　5.［Y］［N］［NG］6.［Y］［N］［NG］7.［Y］［N］［NG］ 　　8. According to Peter H. Gleick, by the year 2025, as many as of the world’s people will suffer from water shortages。 　　9.Two thirds of the freshwater on Earth is locked in。 　　10.In developed countries, before toxic chemicals are released into rivers and lakes, they should be treated in order to avoid。 Part III  Listening Comprehension  (35 minutes) 　　Section A 　　Directions: In this section, you will hear 8 short conversations and 2 long conversations.

Main Street was always the  47  of a town. This street was lined on the both sides with many  48  businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered  49  . There shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to  50  place. Too many automobiles had crowded into Main Street while too few parking places were 51 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers  52 . And open space is what they got when the first shopping centre was built. Shopping centers, or rather malls, 53 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 54 areas to outlying malls. And the growing 55 of shopping centers led in turn to the building of bigger and better stocked stores. By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the  56 of the stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment。 　　［A］designed［F］convenience［K］cosmetics 　　［B］take［G］services［L］started 　　［C］heart［H］fame［M］downtown 　　［D］needed［I］various［N］available 　　［E］though［J］popularity［O］cheapness 　　Section  B 　　Directions:There are 2 passages in this section. 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 Answer Sheet 2 with a single line through the centre。 　　Passage One 　　Questions 57 to 61 are based on the following passage。 　　Culture is one of the most challenging elements of the international marketplace. This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by a set of dynamic variables: language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions. To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience。 　　The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging。 　　The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness。 　　Fortune examined the international performance of a dozen large companies that earn 20 percent or more of their revenue overseas. The internationally successful companies all share an important quality: patience. They have not rushed into situations but rather built their operations carefully by following the most basic business principles. These principles are to know your adversary, know your audience, and know your customer。 　　57.According to the passage, which of the following is true? 　　［A］All international managers can learn culture。 　　［B］Business diversity is not necessary。 　　［C］Views differ on how to treat culture in business world。 　　［D］Most people do not know foreign culture well。 　　58.According to the au
