【正文】 according to the Environmental Protection Agency. In Milwaukee, 400,000 people fell ill in 1993 after drinking tap water tainted with cryptosporidium (隱孢子蟲(chóng) )， a microbe (微生物 ) that causes fever, diarrhea (腹瀉 ) and vomiting. THE SOURCE Where so contaminants e from? In developing countries, people dump raw (未經(jīng)處理的 ) sewage(污水 ) 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 (飲水傳染的 ) diseases. In developed countries, manufacturers use 100,000 chemical pounds to make a wide range of chemicals pollute water when released untreated into rivers and lakes. (Certain pounds, such as polychlorinated biphenyls (多氯化聯(lián)二苯 )， 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 (稀釋劑 ) down the drain。 all of these 中國(guó)最大的管 理 資料下載中心 (收集 \整理 . 大量免費(fèi)資源共享 ) 第 7 頁(yè) 共 43 頁(yè) 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 insects but that pollute water as well. Farmers also use nitrates, nitrogenrich fertilizer that helps plants grow but that can wreak havoc (大破壞 ) 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 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. 中國(guó)最大的管 理 資料下載中心 (收集 \整理 . 大量免費(fèi)資源共享 ) 第 8 頁(yè) 共 43 頁(yè) “ 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.” 提示 :在實(shí)考試卷中， 810 題在答題卡 1 上。 1.
