表推測的情態(tài)動詞
情態(tài)動詞must, can, may, could, might都可以表示推測。
◆must表示對現(xiàn)在的狀態(tài)或現(xiàn)在發(fā)生的事情很有把握的推測， 意為“一定； 準是”，可能性為100%。
如：
You have studied for a long time. You must be tired.
PART ②
Grammar Focus
◆may, could, might這三個詞表示的可能性較小， 意為“有可能； 也許”， 可能性占20%至80%。 如：
My friend has lost his watch. This may /might / could be his, but I’m not sure.
◆can’t 表示很有把握的否定推測， 意為“不可能”，可能性為0%。 如：
The blue motorbike can’t be your mother’s. Hers is yellow.
表推測情態(tài)動詞的用法
一、根據(jù)被推測的時間，確定動詞的形式。
— Good morning. I’ve got an appointment with Miss Smith in the Personnel Department.
— Ah, good morning. You must be Mrs. Brown.
“情態(tài)動詞+do”形式：表示對現(xiàn)在
或?qū)砬闆r的推測。
— Tom is never late for work. Why is he absent today
— Something must have happened to him.
2. “情態(tài)動詞 + be + doing”形式：表示對此時此刻正在發(fā)生的事情的推測。
He may/might be waiting for us at home.
3. “情態(tài)動詞+have done”形式：表示對過去情況的推測。
二、根據(jù)猜測語氣的強弱，選擇情態(tài)動詞。
在肯定句中表推測，
must語氣最強， 表示“肯定，一定”；
could, may, might語氣依次減弱，表示“可能， 也許”。
Some people who don’t like to talk much are not necessarily shy; they may just be quiet people.
2. 在否定句中表推測，
can’t, couldn’t語氣最強，表示“不可能”；
may/might not語氣較弱，表示“可能不”；
mustn’t 表示“禁止”，不用于否定推測。
You can’t be hungry already — you had lunch only two hours ago!
must表推測只用于肯定句，如果要表示否定意義，則要用can’t；
can表推測多用于否定句和疑問句，而用于肯定句一般指“客觀可能性”，說明人或事物一時的特點。
三、某些情態(tài)動詞表推測時的用法限制。
e.g. Tigers sometimes can be very kind.
情態(tài)動詞 用法 例句
must 表示很有把握的推測，意為“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!
