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 Cent

5、ral 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 beco

6、me 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 pr

7、ojects 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 Ins

8、titute for studies in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as onethird of the world's projected 8.3 billion people will suffer from water shortages.Where Water GoesOnly 2.5 percent of all water on Earth is freshwat

9、er, water suitable for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Twothirds 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

10、 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 basi

11、n 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 wi

12、ll be severe shortages and damage to the aquatic environment."Close to HomeWater 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 aquifer

13、s, 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 north

14、west 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 unknowin

15、gly 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 SourceWhere so contaminan

16、ts 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 r

17、ange 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 antifree

18、ze, 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 th

19、at kill weeds and insects but insects but that pollutes water as well. Farmers also use nitrates, nitrogenrich fertilizer that helps 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 b

20、odies 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 loca

21、l solutions to waterrelated problems; governments, for instance, would be better off building smallscale 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 Glei

22、ck. "There has to be a strong push on the part of everyonegovernments 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 projec

23、ts 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 ground water shrinkage and tap water pollution.5. According to the passage all water pollutants come from household waste.6. The people livi

48、47 to 56 are based on the following passage.Shopping habits in the United States have changed greatly in the last quarter of the 20th century. 47 in the 1900s most American towns and cities had a Main Street. Main Street was always the heart of a town. This street was lined on the both sides with ma

49、ny 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

50、 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 needed. And open space

51、is what they got when the first shopping centre was built. Shopping centers, or rather malls, 52 as a collection of small new stores away from crowded city centers. 53 by hundreds of free parking space, customers were drawn away from 54 areas to outlying malls.

52、 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.

55、rketplace. 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

56、, 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

57、cultureone 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

58、still far from converging.The other school proposes that companies must tailor business approaches to individual cultures.
