Summary
情态动词表示推测
情态动词must，can，could，may和might均可表示推测，可以对过去、现在或将来的情况作出语气强弱不同的推测。
1. must “一定；必定”，表示很大的可能性，只用于肯定句中。 e.g. The book is gone. He must take it to school.
【注意】mustn’t “禁止, 千万不要”，不表推测。
e.g. John, you mustn’t play football on the street.
We should keep quiet in the library. We mustn’t speak loudly.
3. may, might, could都能表示“可能”。could, might语气更委婉， might语气最为缓和，含义更不确定。
e.g. There could be life on some of the planets.
They may not know his address. I’m not sure about that.
She told me that she might go to Hawaii this winter.
2. can 常用于否定句或疑问句中表示惊异、怀疑、不相信等。
can’t 表示“不大可能”。
e.g. What can he mean
The door is locked. He can’t be at home.
对不同情况的推测
1. 情态动词+动词原形：对现在或将来的情况进行推测。
如：
You must be tired after your long walk.
Don’t play with the knife. You could cut yourself.
Our team might win the basketball match.
2. 情态动词+ be + 动词-ing形式：对此时此刻正在进行的情况进行推测。如：
There’s a lot of noise from next door. They must be having a party.
Mr. Li is not in his apartment. He might be working at his office.
3. 情态动词+ have + 过去分词：对过去的情况进行推测。如：
I couldn’t have left my bag on the bus.
They must have got lost or they’d be here by now.
Tom didn’t leave till three o’clock. He may/might have missed the train.
情态动词表示推测的用法
(3)“there+情态动词+be+主语+动词 -ing 形式”表示“可能/或
许/一定……做……”。
e.g. It is noisy; there might be some dogs barking.
太吵了，可能是有些狗在叫。
must 在表示肯定推测时，意为“一定”，但是用于否定句时，mustn’t 却表示“不能；禁止”，而不是“不一定”。
