情态动词用法(1)

初中范围内要求掌握的情态动词

1. can的用法：（1）.表示能力. 此时may和must均不可代替它。如：She can swim fast, but I can’t. （2）.表示请求, 许可，常在口语中。如：Can I use your pen? You can use my dictionary. （3） .表示推测，意为“可能”，常用于否定句和疑问句中，此时can’t译为“不可能”。如： Can the news be true? —Can it be our teacher?—No, it can’t be our teacher. He is on a visit to the Great Wall.
7. should的用法：

should意为“应该”，可表示劝告、建议、义务、责任等。与ought to基本同义, 可互换。如： We should protect the environment.
5. need的用法：

（1）.need表示需要、必须，主要用于否定句和疑问句中，其否定形式为needn’t，意为“没有必要，不必”。用need提问时，肯定回答为must，否定回答为needn’t或don’t have to。如： —Need I stay here any longer? —Yes, you must ./—No. you needn’t /don’t have to. (2).need还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语后边多接动词不定式。如： I need to do it right now. He needs to learn more about the girl.

Book 3 Unit 1 Grammar 情态动词 (一)

Book 3 Unit 1 Grammar 情态动词情态动词can，may，must，should，shall，will的用法比较情态动词有一定的含义，表达某种感情和说话的口气，不可以单独作谓语动词。

所以情态动词没有人称和数的变化，后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。

个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去，现在或将来。

一．can / could 与be able to的用法比较1．can “能够，会”，过去式为could，表示能力，与be able to同义。

但be able to有各种时态，还可以表示成功地做了某事。

在否定句中can，could和be able to无区别。

He can speak English. 他会说英语。

He could speak English at the age of six. 他六岁就会说英语了。

I can’t / I will not be able to come this afternoon. 今天下午我来不了。

The fire spread quickly, but they were able to get out.火势蔓延得很快，但他们都成功地逃出来了。

2．can表示可能，怀疑，不相信或惊异的态度。

而could既可以表示过去也可以表示现在的“可能”，其可能性比can小。

Accident can happen any time. 事故随时都会发生。

This cannot be done by him. 这决不可能是他干的。

It could be true. 这也许是真的。

3．can / could 表示允许，could语气更委婉。

在回答对方提问时要用can，不用could。

-Could / Can I ask you a question?-Yes, of course you can.4．can / could + have done的否定式或疑问式表示对过去发生事情的不肯定或怀疑。

小六英语第11讲：情态动词(1)

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。
