Hardly ___________ the papers on his desk when the door burst open.

题目

Hardly ___________ the papers on his desk when the door burst open.
A.he collected B.he had collected C.did he collect D.had he collected
选出答案并请说明原因,
那为什么要用过去完成时呢？

答案

D 这个题目要注意两点：
首先hardly放在句首要部分倒装
第二,要注意时态问题,要用过去完成时,表示这个动作先发生.
如果用正常的语序应该是：
He had hardly collected the papers on his desk when the door burst open.
他刚整理好桌上的文件门就突然开了.
