题目内容

It seems water ______ from this tap for some time. We’ll have to take it apart to put it right.    

 A. had leaked        B. is leaking        C. leaked       D. has been leaking

D


解析:

D根据句中时间状语for some time以及后一分句的动词时态可知,选项动词动作强调到现在为止并仍在继续,故应排除选项A、C。由于选项B现在进行时不可与一段时间状语连用,所以排除选项B,选D现在完成进行时。
