题目内容
11.By the time I got to the check-out,I realized that I _____ my purse at my office.( )| A. | have left | B. | had left | C. | left | D. | was leaving |
分析 当我到结账处时,发现自己把钱包落在办公室了.
解答 正确答案:B.根据句意可知钱包落在办公室动作在前,结账意识到此事动作在后,所以发生在过去的两个动作,之前的用过去完成时(had+done),所以划线处填写had left,故选择B.时间状语by the time表示当/到…的时候,其引导的从句如是一般过去时,主句要用过去完成时.
点评 本题考查过去完成时,需熟悉此时态的定义,根据动作发生的先后顺序作出判断,也可根据时间状语by the time进行判断.
