1. Y該句的意思是巨大的河流改道水利工程使得咸?？s小。從第二段的中間兩句話可得出結(jié)論。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.與原文意思相同。
2. N該句句意為:巨壩和灌溉工程的建設(shè)好處多于壞處。解題依據(jù)為本文第三段第二句話But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. (雖然產(chǎn)生更多問題，許多國家仍繼續(xù)建巨壩和灌溉工程。)由此可知，壞處多于好處，所以該題與原文之義不合。

6. N該句句意為:美國人將不會(huì)面臨缺水問題。該題解題依據(jù)為文章第七段第二句話But Americans could face serious water shortages, too, especially in areas that rely on groundwater, 顯然本題之意與原文之義不合。
7. NG該句句意為:水利專家Gleick 提供了與水相關(guān)的最佳解決方案。根據(jù)本文第十三段第一句話所述，專家Gleick 并未提供任何最佳解決方案。
-third解題依據(jù)為第四段最后一句話：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.
