新概念英语第一册： 129-130课语法及单词解析

【篇一】

语法 Grammar in use

表示猜测和推断的情态助动词must和can't(2)

must与can't不仅能表达对现在和将来的猜测和推断，而且能表达对过去的猜测和推断——这时可用 must have been表示肯定的推断，用can't have been(而不是mustn't have been)来表示否定的推断，如后面跟进行时则表示对过去正在进行的动作的猜测。请看例句：

You must have been driving at seventy miles an hour.

你当时肯定正以每小时70英里的速度行驶。

I didn't see it. I must have been dreaming.

我没看见。我当时一定是在胡思乱想吧。

She can't have been 29.She must have been 36.

她那时肯定不会是29岁，她一定36岁了。

He can't have been reading. He must have been sleeping.

他那时肯定不是在看书，他准是在睡觉。
