◆can’t 表示很有把握的否定推测， 意为“不可能”，可能性为0%。 如：

表推测情态动词的用法
一、根据被推测的时间，确定动词的形式。
— Good morning. I’ve got an appointment with Miss Smith in the Personnel Department.
— Ah, good morning. You must be Mrs. Brown.
“情态动词+do”形式：表示对现在
或将来情况的推测。
— Tom is never late for work. Why is he absent today
— Something must have happened to him.
2. “情态动词 + be + doing”形式：表示对此时此刻正在发生的事情的推测。
He may/might be waiting for us at home.
3. “情态动词+have done”形式：表示对过去情况的推测。
二、根据猜测语气的强弱，选择情态动词。
在肯定句中表推测，
must语气最强， 表示“肯定，一定”；
could, may, might语气依次减弱，表示“可能， 也许”。
Some people who don’t like to talk much are not necessarily shy; they may just be quiet people.
2. 在否定句中表推测，
can’t, couldn’t语气最强，表示“不可能”；
may/might not语气较弱，表示“可能不”；
mustn’t 表示“禁止”，不用于否定推测。
You can’t be hungry already — you had lunch only two hours ago!
must表推测只用于肯定句，如果要表示否定意义，则要用can’t；
can表推测多用于否定句和疑问句，而用于肯定句一般指“客观可能性”，说明人或事物一时的特点。
三、某些情态动词表推测时的用法限制。
e.g. Tigers sometimes can be very kind.
情态动词 用法 例句
must 表示很有把握的推测，意为“一定”，只用于肯定句。 The light is out. He must be sleeping.

This morning, we found that Jack’s eyes were red. What happened to him We guessed.
Some of the boys thought that he must have played mobile games all night, because he always spent a long time doing that. But some girls didn’t agree. They believed that he must have done his homework very late.
Others thought that he was watching TV the whole night, because there was an NBA game last night. But I didn’t agree with them. His parents were very strict with him, so he couldn’t have played games or watched TV.
Then, we asked him during the break, and he said he cought a bad cold. Poor Jack!
