三、情态动词的常见用法：
1.can和could的用法
(1)can/could 表示“能力;许可;可能性”等。could 为 can 的过去式。如：Can I use your book?我可以用你的书吗?
(2)can 用在疑问句中，表示征求意见、请求许可，答语仍用 can; could 用在疑问句中，比can 更委婉、客气，是一种礼貌的说法，并不表示过去时态，答语用can，而不能用could。
Eg: -Could you tell me the way to the park?你能告诉我去公园的路吗?
-Sorry. I can't. I'm new here。不好意思，我不知道。我是新来的。
[注意]
①can 和could 只能用于现在时和过去时两种时态。
②另外， can't 可表示否定推测。
2.may和might的用法
may/might 意为“可以”，表示同意、许可或请求对方许可，也可表示祝愿。
might 是may 的过去式，有两种用法：一种表示过去式;一种表示虚拟语气，使语气更加委婉、客气，或表示可能性更小。
以may开头的一般疑问句，其否定回答用mustn't。
Eg: MayI use your book? 我可以用你用的书吗?
He might be alive. 他可能还活着。
【注意】
can和may都可以用来表示请求或允许，但may比can更正式，更客气。
3.must和should
(1)must意为“必须，应当”，含有一种命令的语气，比较生硬，不容商量。否定形式mustn't, 表示“不得”，“一定不要”。如：
Eg:You mustn't drive after drinking。你绝不能酒后驾车。
①must 与 have to 的区别： must 表示说话人的主观意愿;have to 表示客观需要。
②回答由must 引导的疑问句:
肯定回答：Yes, …must. 如：
-Must I go home now?
-Yes, you must.
否定回答：No，…needn't./No，…don't/doesn't have to.
Eg：-Must I go home now?
-No, you needn't. 。
③must 表示对事物的推测，意为“想必;一定”，只用于肯定句中;表“推测”时，情态动词与动词原形，(常为be动词)连用，
如：The man must be your teacher。那个人一定是你的老师。
(2)should意为“应当，应该”，表示建议或劝告，语气比较委婉，客气。否定形式为shouldn’t。
Eg: You should get up early.
You shouldn't eat too much sugar.
4.will和would
1)用于疑问句，表示说话人向对方提出请求或询问，用would比will更委婉，更客气。
如：Will you please open the window?
Would you like some coffee?
2) would表示建议“你愿意…吗”
-Would you like to go shopping with me?
-Yes, I’d love to. /I’d love to. But I’m busy now.
[注意区别]
①I’d like+n. … 我想要…(接名词)
如：I’d like some water.
②I’d like to + v. … 我想要做…(接动词原形)
如：I’d like to go with Tom.
5、shall用于第一人称 (I, we), 可以表示“将”和表示建议 “……好吗?”
eg： ①Where shall we have dinner?
②-Shall we go fishing? -
- All right. \OK. \Good idea.
