hand in you papers when you__(finish)the test

问题描述:

hand in you papers when you__(finish)the test

have finished
答完就交卷!为甚不用将来完成时一是理解成条件句:(You) hand in you papers when you havefinishedthe test .就是说: if you havefinishedthe test ,then hand in....另一种想法。(You) hand in you papers when you havefinishedthe test .主从句其实动作很近, 要保持一致的时态。
