单元语法

情态动词表示推测的用法

1.概述：一般来说，英语中可用于表示推测或表达可能性的情态动词有can,could,may,might,must

must表示很大的可能性，一般只用于肯定句，意为：肯定，一定，必定

eg:Youmustbetiredafterthelongjourney.

might在表达可能性时语气最弱。May在表达推测时，意为：可能，也许，常用于肯定句和否

定句中Itmay/mightrainthisafternoon.

Myunclemay/mightcomebackthisafternoon,butI’mnotsure.

can,could在表示推测时，常用于否定句，表示有把握的否定推测，意为：不可能，用couldn’t时

语气比较缓和，用can’t时不相信的程度更强一些

Itcouldn’tbeTombecauIsawhimatschooljustnow.

2.用法：

①情态动词+动词原形表示对目前事情的推测ThedictionarymustbeTom’s.

②情态动词+be+动词ing表示对正在发生的事情的推测Hemustbedoinghishomeworknow.

③there+情态动词+be+主语+动词ing表示可能/或许/一定有。。。在做。。。
