题目内容
4.Experiments of this kind ____in both the U.S.and Europe well before the Second World War.( )A. | have conducted | B. | have been conducted | ||
C. | had conducted | D. | had been conducted |
分析 句意为:在第二次世界大战之前这种实验已经在美国和欧洲都进行的很好了.
解答 答案:D. 通过时间状语"before the Second World War"可判断是过去的过去,所以用过去完成时态;另外,Experiments与conduct之间是被动关系,所以本题要用过去完成时的被动语态.
点评 考查这类考点时,要注意句中的时间状语,以确定用什么时态,然后判断相关名词和动词之间的关系,是主动关系用主动语态,如果是被动关系,而且动词是及物动词,则用被动语态.
