题目内容
12.The detective inspected the room for fingerprints,wondering if someone ____ the room.( )A. | entered | B. | enters | C. | had entered | D. | has entered |
分析 侦探查看了房间里的指纹,想知道是否有人曾经进来过.
解答 答案:C.
前面主句的谓语动词用的是一般过去时,由常识可推知,是否有人进入过房间,应该是发生在侦探勘察房间之前的动作,即过去的过去,所以为过去完成时;其中wondering为现在分词短语作状语的用法.故选C.
点评 本题考查了过去完成时的用法:即表示过去某一时间或动作以前已经发生或完成了的动作,该动作发生的时间通常是在"过去的过去".
