解答 31-35 FACGB
31 F.考查對上下文的理解和推理判斷能力.根據(jù)后文的Groundwater does not come from lakes or rivers 地下水不是來自湖泊或者河流,可知空格填寫的是我們每天使用的大部分水是地下水.故選F.
32 A.考查對上下文的理解和推理判斷能力.根據(jù)Drier climates are of course more likely to have droughts 越來越干燥的氣候更容易引起干旱,也就是水資源短缺不只是因為人類的活動,還有干燥的氣候,故選A.
33 C.考查對上下文的理解和推理判斷能力.根據(jù)后文的but there's a lot we can do to lower the number 我們可以做許多事情來降低這個數(shù)字,也就是說考慮下我們每天用水的方式會非常有意義,故選C.
34 G.考查對上下文的理解和推理判斷能力.后文都是節(jié)約用水的一些方法,故選G.
35 B.考查對上下文的理解和推理判斷能力.本段給出了節(jié)約用水的一些做法,選項B與之匹配,故選B.
點評 這是一篇選句填空閱讀.做這類題材閱讀理解時要求考生對文章通讀一遍,做題時結(jié)合原文和空格上下文有針對性選出正確答案.
