题目内容
10.Sofia looked around at all the faces:she had the impression that she _____ most of the guests before.( )A. | has seen | B. | had seen | C. | saw | D. | would see |
分析 句意:Sofia环顾了四周所有的人,她有印象她之前见过大多数这些客人.
解答 答案:B 句子的谓语动词looked 和had都是过去式,说明动作发生在过去.而句末又有时间状语before.说明see的动作发生在句子谓语动词的动作之前,即"过去的过去",应该用过去完成时.A项是现在完成时;C项是过去式;D项是过去完成式.都不符合题意,故选B项.
点评 考查过去完成时.主要看句子谓语动词的时态和时间状语.如果动词的动作是发生"过去的过去",就用过去完成时.
