初中英语情态动词的用法归纳,情态动词用法有哪些
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。

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. 。

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”

初中英语情态动词知识点总结
情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词无人称和数的变化;不能单独使用,必须与其后的动词原形构成谓语
一、 can, could
1) 表示能力(体力、知识、技能)。
Can you lift this heavy box?(体力)
Mary can speak three languages.(知识)
Can you skate?(技能)
此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to则有更多的时态。
I’ll not be able to come this afternoon.
当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。如:
He was able to go to the party yesterday evening in spite of the heavy rain.
2) 表示请求和允许。
-----Can I go now?
----- Yes, you can. / No, you can’t.
此时可与may互换。在疑问句中还可用could,
might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
---- Could I come to see you tomorrow?
---- Yes, you can. ( No, I’m afraid not. )
3) 表示客观可能性(客观原因形成的能力)。
They’ve changed the timetable, so we can go by bus instead.
This hall can hold 500 people at least.
4) 表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。
Can this be true?
This can’t be done by him.
How can this be true?
二、 may, might
1) 表示请求和允许。might比 may语气更委婉,而不是过去式。否定回答时可用can’t
或mustn’t,表示“不可以,禁止”。
----Might/ May I smoke in this room?
---- No, you mustn’t.
---- May/Might I take this book out of the room?
---- Yes, you can. (No, you can’t / mustn’t. )
用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。
2)用于祈使句,表示祝愿。
May you succeed!
3) 表示推测、可能性(不用于疑问句)。
might不是过去式,它所表示的可能性比may小。
1.He may /might be very busy now.
2.Your mother may /might not know the truth.
三、 must, have to
1) 表示必须、必要。
You must come in time.
在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t, don’t have to(不必).
---- Must we hand in our exercise books today?
---- Yes, you must.
---- No, you don’t have to / you needn’t.
2) must是说话人的主观看法, 而have to则强调客观需要。Must只有一般现在时, have to 有更多的时态形式。
1. he play isn’t interesting, I really must go now.
2. I had to work when I was your age.
3) 表示推测、可能性(只用于肯定的陈述句)
1. You’re Tom’s good friend, so you must know what he likes best.
2. Your mother must be waiting for you now.
四、 dare, need
1) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。
1. How dare you say I’m unfair?
2. He daren’t speak English before such a crowd, dare he?
3. If we dared not go there that day, we couldn’t get the beautiful flowers.
2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。
1.You needn’t come so early.
2. ---- Need I finish the work today?
---- Yes, you must. / No, you needn’t.
3) dare和 need作实义动词用时, 有人称、时态和数的变化。在肯定句中,dare后面常接带to的不定式。在疑问句和否定句中,dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。
1. I dare to swim across this river.
2. He doesn’t dare (to) answer.
3. He needs to finish his homework today.
五、 shall, should
1) shall 用于第一人称,征求对方的意见。
What shall we do this evening?
2) shall 用于第二、三人称,表示说话人给对方的命令、警告、允诺或威胁。
1. You shall fail if you don’t work hard.(警告)
2. He shall have the book when I finish it.(允诺)
3. He shall be punished.(威胁)

1) 表示请求、建议等,would更委婉。
Will / Would you pass me the ball, please?
2) 表示意志、愿望和决心。
1. I will never do that again.
2. They asked him if he would go abroad.
3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式,且没有“现已无此习惯”的含义。
1. During the vacation, he would visit me every other day.
2. The wound would not heal.
4) 表示估计和猜想。
It would be about ten o’clock when she left home.
七、 should, ought to

1. I should help her because she is in trouble.
2. You ought to take care of the baby.
2) 表示劝告、建议和命令。should, ought to可通用,但在疑问句中常用should。
1. You should / ought to go to class right away.
2. Should I open the window?
3) 表示推测
should , ought to (客观推测), must(主观推测)。
