——I saw Annie in the market yesterday.
——You _______her; she is still studying abroad.
A. mustn't see
B. couldn't see
C. mustn't have seen
D. couldn't have seen
选哪个 为什么 谢谢
mustn't 怎么不行?
答案D,这个题目应该属于高中英语中情态动词+have done这个考点,重点哦~
1.could have done 表示对过去发生事情的可能推测,加not就有了否定意义了;
2.must have done 表示对过去发生事情的 肯定推测,但是---must加not却表示了禁止以及不许可的意义,与本题题意不符;
3.根据原句时间状语yesterday及句意,表示过去 且 否定,所以答案选D喽~
d
d
couldn't表示不可能
因为是过去看到的~所以+have
mustn't意为绝不可以,表不允许
d
选D
在表示推测的句子中,mustn't是不可以用的。只有这几个词可以用否定:may,might,can,could.其中can't表示不可能。
顺带一提,选D的理由还有一个:要在推测句子中表示过去时,在助动词后用现在完成时表示。
D虚拟语气
must意思不对
