答案与解析

世界的可用淡水资源有限，但农业在利用水资源过程中存在不尽如人意之处，本文指出了其中的一些问题。

1.C细节理解题，由文中第一段第二句“With97%oftheworld'swatertoosaltytobedrunkorusedinagriculture...”可知A选项错误;由第一段第三句“...strangetosomeonefortunateenoughtoliveinahighrainfallcountry...”可知B选项不合文意;第二段前两句指出水资源的重新分配的费用极高，一方面是水利过程本身的造价，另一方面也会对生态造成极大的破坏，所以选项C正确，根据第二段第四句“...itcannotbetransportedfromonesideoftheworldtotheother.”可知D项不正确。

2.C细节理解题。根据文章第三段第二句“...hasresultedina25%reductionofthewaterstores.”可判断A选项不正确;由第一段最后一句可判断B选项错误;由文章最后一句“...fiftyyearsofpumpingwillseethemrundry.”可知C项正确。根据文章第三段最后一句可知D项不正确。

3.A判断推理题。文章前面一部分主要是讲述农业在利用水资源过程中存在的问题，接下来应该是介绍加强水资源管理的方法和措施，所以A选项正确。

4.B主旨大意题。由第一段第二句可知。
