Explain：情态动词must, can, could, may, might 均可表示推测，它们可以对过去、现在或将来的情况进行推测。
推测语气的强弱
1). 表示肯定的推测时，各情态动词语气从弱到强依次为might →may →could→ can →must。
2). 表示否定的推测时，can’t / couldn’t语气较强，意为“不可能”；may not / might not语气较弱，意为“可能不”。
注意：
must的否定形式mustn’t不表示否定推测，而是表示禁止，意为“千万不要”。如：
John, you mustn’t forget to take your English book.
情态动词表示推测时的用法

3). may / might用于肯定句和否定句中。
对不同情况的推测

Don’t play with the knife. You could cut yourself.
