英语翻译
书上They will have moved to the new house when it has been painted.将来完成时用的对吗?

优质解答

They will have moved to the new house by the time it has been painted.这样说更好,by the time是到……为止.其它的都对!

追问：

将来完成时表示在将来某一时间之前已完成的动作。油漆房子在前，住进去在后，那么不是油漆房子用将来完成时吗？

追答：

主句一定得用将来完成时，就是搬进房子那儿，比如： They will have learnt 200 words by the end of this month. 到这个月末，他们就会已经学完200个单词了。
