题型：不详难度：来源：

When she entered the police station, she recognized the man who ______ her at once．

A．was attacking

B．attacked

C．had attacked

D．would attack

答案

C

解析

试题分析：注意时间状语When she entered the police station说明动作与过去有关，动作attack发生在recognize之前，即过去的过去，用过去完成时。句意：当她进入警察局时，她立刻认出之前袭击她的那个男人。
点评：做时态题时，首先要根据时间状语或上下文语境，先确定大范围（过去，现在还是将来），然后与相关谓语动词进行比较先后顺序，确定正确时态。
