题目内容
You must have gone over your lessons very well yesterday,________?
- A.don't you
- B.didn't you
- C.haven't you
- D.mustn't you
B
这句句子的意思是“你昨天肯定很好地复习了功课。”这里的must表示猜测,是“一定”的意思,而不是命令的语气“必须”,所以不能用mustn't或needn't来反问。而句子中出现了明确的过去时间yesterday,因此应该用didn't.请注意下列例句:
They must have practiced for long, haven't they?
They must have studied the lesson yesterday, didn't they?
They must obey the law, mustn't they?
They must go home right now, needn't they?
