动词时态与语态
一（2014安徽卷）23．The twins, Who their homework, were allowed to play badminton on the playgrou nd. A. will finish B. finish C. have finished D. had finished
考点】考察时态 【答案】D 句义：已经完成了他们的家庭作业，这对双胞胎被允许在操场上打羽毛球。根据句义可知他们完成作业是在被允许到操场上打羽毛球之前。而他们被允许打羽毛球已经使用了一般过去时，所以完成作业应该使用过去完成时。故D正确。
【举一反三】--- Peter, do you know who____ my dictionary ? A. has taken away B. was taking away
---Sorry , I don’t know . I didn’t do it . C. had taken away D. is taking away
【答案】A 试题分析：句意：--皮特，你知道谁把我的字典拿走了吗？--对不起，我不知道，我没有拿。这里拿走发生在过去，强调对现在造成的影响，不知在什么地方，故用现在完成时。
