1. mustmust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。eg：He must knw the answers. 他肯定知道答案。 He can’t knw the answers. 他肯定不知道答案。
2. can / culdcan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”。eg：He can’t pick her schlbag up. 他不可能拿了她的书包。culd 表示某事有可能发生或可能是事实。eg：Dn’t eat it. It culd g bad. 不要吃它，可能坏了。 The plane culd be put ff by the strm. 这趟飞机可能会因为暴风雨而 推迟。
3. may / mightmay, might表示推测“可能性”时，意思是“可能”，“也许”。might不表示过去时态，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。eg：He may / might nt be at hme, but I’m nt sure. 他可能不在家，不过我也不确定。
情态动词表示推测可以分为以下几种情况: (1)情态动词+ d  此结构表示对现在或将来情况的推测和判断。 eg： —D yu knw where she is nw? —I think she might travel in Beijing.     (2)情态动词+ be ding  此结构表示对现在或将来正在进行的情况的推测和判断。 eg：At this mment, my father can’t be wrking in the ffice.
