----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。
否定形式mustn't, 表示“不得”,“一定不要”。
如:You mustn't drive after drinking.你绝不能酒后驾车。

第11讲情态动词情态动词这类词本身虽有意义,但不完整。
它们表示说话人的能力、说话人的语气或情态,如“可能”、“应当”等。
这类动词有can, may, must, need, dare, could, might等。
它们不能单独作谓语,必须与行为动词(原形)一起作谓语,表示完整的意思,例如:I can dance.(我会跳舞。
)can, 能, 会Be able to代替can, 也可以表示能力。
但can只有一般现在时和一般过去时(could), 而be able to则有更多的时态形式,例如:My little brother has been able to write.2)表示允许,准许,这时can与may可以互换,例如:Can/May I borrow your bike tomorrow?Yes, of course. You can/may use my bike tomorrow.You can’t smoke here.表示请求时肯定的回答方式有:Yes, you can.∕Of course.∕ Certainly. ∕Sure否定回答方式有:No, you can’t∕ No,you mustn’t.3)表示客观可能性,用在否定句和疑问句中表示说话人的怀疑、猜测或不肯定。
例如:He cannot/can’t be there.Can this news be true?4)could除表示can的过去式外,在口语中还常代替can,表示非常委婉的请求。
这时could和can没有时间上的差别。
例如:Could/Can you tell me if he will go tomorrow?Could/Can I ask you something if you are not busy?2.may和might1)表示“准许”和“许可”,这时可与can替换。
例如:May (can) I use your dictionary for a moment?May I take these magazines out of the reading r oom? No, you mustn’t.2)表示说话人的猜测,认为某事“可能”发生,例如:Where’s John? He may be at the library.Mr. Green hasn’t talked with her. He may not know her.He may be at home.Maybe he was at home.3)might除表示may的过去式外,在口语中还常代替may, 表示非常委婉的请示或实现的可能性较小。
这时might和may没有时间上的差异。
例如:Might (May) I speak to you for a few minutes? Might I have a photo of your family?3.must1)must表示说话人的主观意志,表示义务、命令或必要、应当和必须等。
现在式与过去式同形。
如:I must go to school today.He told me I mustn’t leave until my mother came.2)must表示推测,“一定是”、“准是”,例如:They must be very tired. Let them have a rest.Jack doesn’t look well. He must be ill.注意:➢have to表示“必须”、“不得不”,它不仅能代替must, 用于现在时和过去时以外的其他时态,表示说话人的主观看法,而且又表示客观上的需要。
例如:If we miss the last bus, we shall have to walk home.The ship started to go down slowly. We must leave the ship.➢在回答must的疑问句时,否定回答常用needn’t表示“不必”,例如:Must I return this book to you in two weeks?(这本书我两星期以后必须还你吗?)Yes, you must.(是的。
)No, you needn’t.(不,不必了。
)4.needneed(需要)既可作情态动词,又可作实义动词。
1) need作情态动词时,只用于否定句或疑问句。
例如:It’s warm today. You needn’t put on your coat.Need I post your books to you?2) need作及物动词时:need sth ∕to do sth ∕doing sth四.情态动词常见句型1、Can I help you? ——Yes, please. / No, thanks.2、Can + 主语+ 动词原形?
