情态动词本身有一定的词义, 表示说话人的
情绪、态度或语气, 但它们不能单独作谓语,
只能和行为动词原形一起作谓语, 表示完整
的意思。
本单元我们主要接触的情态动词有:
情态动词
Grammar
1. can
(1) 表示能力, 意为“能, 会”。
例： Can you play tennis
你会打网球吗？
(2) 表示请求、允许，意为“可以”。
Can you pass me that book
你能把那本书递给我吗？
You can use my bike.
你可以用我的自行车。
否定式用can’t.
提示:
表示否定推测“不可能”, 常用can’t, 。
例：I saw him playing football just now. He can’t be in the classroom.
—Can I borrow your ruler, please
—Yes, you______. But you must return it to me before
lunchtime. 【江苏徐州中考】
A. have B. can C. must D. used to
【解析】考查情态动词。答句意为“是的，你可以，但你必须在午饭之前归还给我”, 所以选择B。
The man ______be my English teacher. He has gone to Canada. 【湖南益阳中考】
A. might B. must C. can’t
【解析】考查情态动词的用法。must表肯定的推测，意为“一定”，可能性较大，might表示肯定推测，“可能”，可能性较小，can’t表示否定推测，意为“不可能”。根据句意：那个人不可能是我的英语老师，他去加拿大了。故选C。
2. could
(1)can的过去式，意为“能，会”，表示过去的
能力。
例：He could draw pictures well when he
was young.当他小的时候，他的画就能画得
很好了。
(2)could用在疑问句中，表示更加委婉的请求,回答用
can。
例：—Could I use your dictionary

3. must
(1) 表示“必须”, 强调主观意愿。
例： I must go now. 我现在必须得走了。
You must finish it on time. 你必须按时完成。
(2) 表示肯定推测“一定”, 一种可能性很大的推测, 一般用于
肯定句中,否定句中则要用can来代替。
例： —There’s someone knocking at the door.
有人在敲门。
—It must be Jim. 一定是吉姆。
(3) mustn’t意为“不要”, 表示禁止或不允许。
例：You mustn’t sit on the stairs. 你不必坐在楼梯上。
(4) 以must开头的一般疑问句,肯定回答用must, 否定回答
要用needn’t或don’t have to, 表示“不必”而不用mustn’t。
例: —Must I return the book now 我必须先在归还这本书吗？
—No, you needn’t. / Yes, you must. 不，不必。/是的，必
须现在归还。
( )1. —Must I stay at home and take care of her？

4. may和might
(1)表示允许
①表示请求允许(即请求别人允许自己做某
事), 两者都可用, 只是 might 表示的语气较
委婉(但并不表示过去)。
例: May I come round in the morning 我
早上来行吗
I wonder if I might use your phone. 不知可
否用一下你的电话。
②表示给予允许(即自己允许别人做某事)，只能用may
而不能用might。
例：You may stop now. 你现在可以停下来了。
You may leave when you’ve finished. 你做完以后就
可以走。
注意：might 表示允许通常不表示过去，但是在间接引语(即宾语从句)中可以用作 may 的过去式来转述已给予的允许。例：She said that he might take her dictionary. 她说他可以拿她的词典去用。
(2)表示推测
两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小(注意此时的might并不表过去)。在句型使用方面：may通常用于肯定句或否定陈述句，一般不用于疑问句(疑问句中用 can)，而might 则可用于肯定句、否定句或疑问句。
例：He may be at home now, but I’m not sure. 他可能在家里，但是我不确定。
Might he know the answer 他可能知道答案吗？
Peter ______ come with us tonight, but he isn’t very sure yet. A. must B. may
C. can D. will
5. should
(1)表示“应该”，常用来表示劝告、建议, 认为“某人应该做某事”或“有义务责任做某事”。
例：We should obey traffic laws.
我们应该遵守交通法规。
You shouldn’t have made this kind of silly mistakes.
你不应该犯这种愚蠢的错误。
这时它可以和 ought to, be supposed to 互换使用 。
(2) should (ought to)表示推测时，是指有一定根据的推测，意为“可能、该”。
例：—When can I come for the photos I need them
tomorrow.我什么时候可以来拿这些照片？我明
天需要它们。
—They should be ready by 12:00. 十二点的时候就
可以准备好了。
It’s nearly seven o’clock. Jack should be here at any moment.快七点了。杰克可能快到了。
