情态动词表推测，后跟------------
解题思路： 情态动词表推测时，后面加动词原形。
解题过程：
▲在肯定句中：
在肯定句中可使用的情态动词有must, may, might, could，其肯定程度逐渐减弱，must表示一种十分肯定的推测，意为“一定，肯定”。may表示一种没有把握的推测，意为“可能”； might意为“或许”； could意为“可能”,may / might, could在表示推测时，无时态区别，只表示语气差别。 如：
①You have worked hard all this week. You must be tired.你辛苦工作了一周，一定累坏了。
②Will you answer the phone? It could / may / might be your mother.
请你接一下电话好吗？可能是你的母亲打来的。
③According to the radio, it could / may / might rain this evening. 根据广播，今晚可能下雨。 ▲ 在否定句和疑问句中中：
can表示推测主要用于否定句和疑问句。can’t表示有把握的否定推测，意思是“不可能”。如：
①I saw her just a few minutes ago in a supermarket. She can’t be here. 几分钟之前我看见她在超市，她不可能在这儿。
②The sweater can’t be Tom’s, it’s too small for him. 这件毛衣不可能是汤姆的，他穿太小了。
