----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。

情态动词没有人称和数的变化,后面的动词要用原形。

二、情态动词的种类三、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。

如: —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。

如: May I 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shouldmust意为“必须,应当”,含有一种命令的语气,比较生硬,不容商量。

之蔡仲巾千创作情态动词有can (could), may (might), must, have to, s hall (should, will (would), need (needed), ought to等。

情态动词无人称和数的变更；不克不及单独使用，必须与其后的动词原形构成谓语一、 can, could(过去式）1) 暗示能力（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）Can只有一般现在时和一般过去式；2) 暗示请求和允许。

-----Can I go now?----- Yes, you can. / No, you can’t.3) 暗示客观可能性（客观原因形成的能力）。

They’ve changed the timetable, so we can go by bus inste ad.This hall can hold 500 people at least.4) 暗示推测（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, might1) 暗示请求和允许。

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，暗示“不成以，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...？在口语中更罕见。
