　　1.【解析】[Y]该句的意思是巨大的河流改道水利工程使得咸海缩小。从第二段的中间两句话可得出结论。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.与原文意思相同。

　　6.【解析】[N]该句句意为:美国人将不会面临缺水问题。该题解题依据为文章第七段第二句话 But Americans could face serious water shortages, too, especially in areas that rely on groundwater, 显然本题之意与原文之义不合。

　　7.【解析】[NG]该句句意为:水利专家Gleick 提供了与水相关的最佳解决方案。根据本文第十三段第一句话所述，专家Gleick 并未提供任何最佳解决方案。
