分析 本文是一篇记叙文.本文讲述了作为人类最重要而自然资源之一,河流的起到的重要作用以及面临的污染问题.
解答 76.located 考查动词的时态语态.根据句意,这里表示"坐落于",且主语为物,故用"be located+介词+地点"表被动.
77.least 考查固定搭配.根据句意,这里表示几乎每个城市都至少有一条河流,故用at least.
78.plays 考查动词的时态和固定搭配.根据句子成分分析可知,这里that用来引导定语从句且在句中做主语,表示"在…中起重要作用"要用"play an important part in",再根据主谓一致原则,故填plays.
79.transportation 考查名词.根据前面的介词for可知,这里要用名词作宾语,故填transportation.
80.drink 考查非谓语动词.做目的状语的非谓语动词只能用to do不定式表示,前面已经有了to,故填动词原形drink即可.
81.However 考查连词.根据前后的逻辑关系,这里表转折且有逗号,故填However.
82.rivers 考查名词.根据句意,这里表示那些住在河边的大城市和工厂经常会制造一些问题,河流不止一条,故填rivers.
83.in 考查介词的固定搭配.表示"在某方面的增长"要用grow/increase in,同时根据后文的 increase in number可知,这里要填介词in.
84.polluted 考查动词的时态语态.根据常识,河流是被污染,表被动,谓语动词要用be/become done的形式,故填polluted.
