After they _____________ cleaning the room,they ________home yesterday.
Answers: finished, went & had finished ,went
Which answer is better? Why?
Thanks !
答
had finished ,went
答
我认为第二个
打扫完房间，用过去完成时吧
答
after 引导的状语从句,既可用一般过去时,也可用过去完成时.只是用过去完成时,更强调主句动作发生的时间在从句动作之后.
显然finish cleaning the room是在went home之前发生的,所以应用完成时.
答
选后者,考查过去完成时的运用。回家是过去时,打扫是在回家之前已经完成，故是过去完成时。
