题目内容
16.-How come the lake smells so terrible?-Because large quantities of water .( )
A. | have polluted | B. | are going to pollute | ||
C. | had been polluted | D. | have been polluted |
分析 --这个湖泊怎么味道那么难闻呀?
--因为大量的水资源已经被污染了.
解答 答案:D.
根据句意"大量的水资源已经被污染了"可知,水质的变差是造成湖泊难闻的原因,所以用现在完成时,排除B和C;water与pollute为逻辑上的动宾关系,故用被动语态,排除A;另外large quantities of修饰不可数名词和可数名词的复数时后面的谓语动词一律用复数;故选D.
点评 本句考查动词的时态和语态,结合句意和逻辑关系来判断相关的时态语态.
