情态动词（Mdal verb）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法，多用来表达能力、意愿、义务、许可，还可以表示推测。英语中表示推测的情态动词主要有 must, can, culd, may, might, can’t等。
must ＞ can ＞ culd ＞ may ＞ might ＞can’t
must表示可能性最大的肯定推测，意思是“一定、准是”。只能用于肯定句。如果要表示“一定不”，应该用can’t。
如：她没接电话。她肯定是出去了。
She isn’t answering the phne. She must be ut.
He must knw the answers.
may, might表示推测“可能性”时，意思是“可能”，“也许”。might语气更委婉，可能性更小。may, might表推测时，可用于否定句，但不用于疑问句。
如：他可能不在家，不过我也不确定。
He may/might nt be at hme, but I’m nt sure.
迈克为什么没来上课？他可能生病了。
Why didn't Mike cme t class? He may/might be sick.
can表示推测“可能性”时，一般用于否定句或疑问句。can在疑问句中意思是“会，可能”。
如：他不可能拿了她的书包。
He can't pick her schlbag up.
culd 表示某事有可能发生或可能是事实。
如：不要吃它，可能坏了。
Dn't eat it. It culd g bad.
（1）情态动词表示推测时，无时态区别，只有语气差别。 表示推测的情态动词的语气强弱顺序如下（由强到弱）：
must ＞ can ＞ culd ＞ may ＞ might
（2）含有must的句子（must表推测）变为否定句时，要用can’t
如：He must be at hme.
