中考情态动词考点

(一)情态动词概说

1.情态动词也是“辅助性”动词,用来表示说话人的语气或情态。情态动词所表示的情态有:请求、命令、允诺、可能、需要、敢于、愿望、义务、能力等。

2.情态动词本身有词义,但词义不完全,不能单独用作谓语,没有人称和数的变化,且后面只跟动词原形。如:

她会唱英文歌曲。

She cans sing an English song.(F)

She can sings an English song.(F)

She can sing an English song.(T)

3.有些情态动词的过去时与其原形相同,有些与原形不同。

(1) 与原形相同的有:

must --- must ought to --- ought to

(2) 与原形不同的有:

can --- could will --- would

may --- might shall --- should

need --- needed dare --- dared have to --- had to

(三)情态动词的否定形式:

cannot --- can?tcould not --- couldn?tmay not--- mayn?t

might not--- mightn?t must not --- mustn?t will not --- won?t

would not --- wouldn?t need not --- needn?t shall not --- shan?t

should not --- shouldn?t ought not --- oughtn?tdare not --- daren?t

(四)常用情态动词的用法:

1.can与could

1). can

(1)表示体力或脑力方面的“能力”,也能表示根据客观条件能做某事的“能力”。

He can drive.

Can you jump as far as he did?

I can?t catch up with Jim.

can与be able to二者都表示“能够”,区别是:can只有现在时和过去式,而be able to可用于各种时态。如:

I?ll be able to speak French in half a year.

He hasn?t been able to finish it on time.

(2)表示允许:

You can go now.

Can I use your bike?

(3)表示推测:

Who can it be?

It can?t be true.

can表示猜测或怀疑只用于疑问句及否定句中。

2). could

(1)can的过去式,表示过去有能力及过去的可能性。

He couldn?t climb up the mountain.

The news could be true.

(2)表示客气地请求或委婉地陈述意见。

Could you go skating with me tomorrow?

I?m afraid I couldn?t give you an answer tonight.

(3)表示惊异、怀疑、不相信等态度

How could he say that?

He couldn?t be in Beijing.

2.may与might

1). may

(1)表示请求、许可、可以

—May I use your dictionary?

—Yes, please/certainly.

(2)表示推测说话人的猜测,认为某一事情“或许”或“可能”发生。

It may rain this afternoon.

I may leave for Hangzhou next week.

(3)may用于感叹句中可以表示祝愿或愿望。

May you do well!

May you have a good time!

2). might

(1)用作may的过去式。

We didn?t know that he might be our new teacher.

The accident might happen the day before yesterday.

(2)替代may来表示现在时间的动作,主要于推测(但其可能性比may更低)。

I?m afraid it might snow tomorrow.

You might meet him at the conference.

The movie might have finished now.

(3)委婉地表示请求(不是过去式)。

Might I ask you a question?

Might you go there with me?

3.must

(1).表示义务,命令或必要。

Soldiers must obey orders.

We must be strict with ourselves.

(2).表示肯定的推测:一定

He must be at home.(对现在的猜测)

I think you must have made a mistake.(对过去的猜测)

He must be our new teacher.

He can?t be our new teacher.

(3)此外还要弄清楚must与have to的区别

4.will与would

1). will

(1)表示意愿、决心。此时可用于各种人称。

He won’t come to see you.他不愿来见你。(表示意愿)

I will try my best to catch up with her.我将尽最大努力赶上她。(表示决心)

(2)表示请求,此时仅限于“will you (please)??”句型中,仅用于第二人称和疑问句中。 Will you please buy me an English-Chinese dictionary when you go to the bookstore?

Will you have some rice?

2). would

(1)will的过去式,表示过去的意愿和决心。

He said he would do everything for her, but she said she would never see him again.

They believed that we would help them.

(2)用于现在时,表示委婉地提出请求,建议或看法。此时would的用法比will更加委婉。 Would you please show me the way to the museum?

I would like to say something about it.

will和would用于“劝某人接受??”时,只能用some,不能用any。如:

Would you like some fish? 吃点鱼好吗?

5.shall与should

1). shall

征求对方意见或请求,用于第一、三人称。表示“要不要???”、“??好吗?”

Shall I open the window?

Shall the doctor come?

2). should

(1)should意思是“应该”,表示劝告或建议(=ought to)

You should wash your hands before dinner.

We should help each other.

(2)用来表示可能性或猜测。

He should be in the office now.

I should be right.

(3)should有时能表示说话人的情感等。

It’s funny that they should be confident.(表示轻视)

Why should I do that for you?(表示不满)

(4)should后接动词不定式(不加to)时,若用于肯定句,表示某件事本应该完成却未完成;若用于否定句,则表示某事不该发生却发生了。

You should have told us the truth.(应该告诉却没有)

He should have known the importance of it.应该知道却不知道)

We shouldn’t have left so early.(不应该早出来,可已经做了)

6.need

1)need意思是“需要,必须”,主要用于否定句和关系问句中。

You needn?t come so early.

Need I take part in the Party?

2) need引导的疑问句,肯定回答时多用must,否定回答时用needn’t。

Need he come?

Yes, he must.

No, he needn?t.

3) need后接名词做宾语时,表示“需要”某件事物,此时用作实义动词,与一般的实义动词用法完全一样。如:

We need three apples.

He doesn?t need so many books.

7. ought

ought只有一种形式,后面常与to连用,意思是“应该”。

You ought to visit us often.

Sorry, I ought to leave now.

在表示“应该”时,ought to的语气比should要强,比must稍弱。

8. dare

1) dare意思是“敢”,用于肯定结构中时,后接加to的动词不定式。

The boy dared to climb up the tree.

She should dare to question her teacher.

2)dare用于否定句或疑问句中时,与大多数的情态动词一样,后接不带to的动词不定式。Don't dare do that again!

The poor girl dare not go home.

9.had better

You had better see a doctor.

You had better not leave now.

Had I better wait for her?

used to do / be used to doing / be used to do…

used to do 表示过去常常发生的动作,强调过去,只用于过去,注意用 to do,不用doing形式;

而be used to doing 意为“习惯做…”, be 可有各种时态;

be used to do 意为“……被使用去做……,” 为被动语态形式。

My father used to eating meat.

She is used to eating meat.

He wasn?t used to eating in a restaurant.

Knives are used to cut things.

(五)含有情态动词的疑问句

1. 由 can、may、must构成的疑问句

(1)句式: Can/ May/ Must… + 主语+动词原形+….? 如:Can you repair the car? Could he be a good student? May I borrow your ruler?Must we clean the room now?

(2)对 may 引出的问句,可以有下列回答方式:Yes, of course. Yes, certainly. Sure. No, you mustn?t. No, you can?t.

(3)对must引出的疑问句,回答为:Yes, …must. No,… needn?t/ don?t have to.

2. will, would, shall 的用法

(1)will 在一般疑问句中表示客气的“请求、劝说”。 would 是will 的过去式,语气更加

客气、委婉。Would you show me your picture book? Will you please give me a call?

(2)对 will/ would you…的回答方式有以下几种:Yes, I will. (No, I won?t.)Sure . (I?m sorry , I can?t.)All right. Certainly. (No, thank you .)Yes, please.

(3)shall引出的疑问句用于第一人称, 表示征求对方意见或客气的请求。其回答方式有以下几种:Yes, please. All right. No, thank you.

(六)不同情态动词的否定意义也不同

1. (1) can?t可译为“不会”, 如:I can?t play basketball. 我不会打篮球。 (2)当句子表推测时,用can?t 表达不可能, He can?t be ill. He is playing chess with Tom.(3)can?t 还可用来回答“ May I …? ” 这样的问句。May I come in ?No, you mustn?t. / can?t. (4) can?t 还

篇二:考点二 情态动词 中考考点

考点三 情态动词

情态动词表示说话人对某一动作或状态的态度,表示“可能”、“应当”、“必要”等含义,但其本身词义不完全,不能独立作谓语,必须和动词原形连用。情态动词没有人称和数的变化。其否定形式一般是在情态动词后加not (have to除外),其疑问形式是将情态动词提至主语前。情态动词数量不多,但用途广泛,初中考点主要有:can(could), may(might), must, need, shall(should), will(would)。

情态动词的特征:

1. 情态动词本身有词义但不能单独作谓语,情态动词+行为动词原形 一起构成谓语。

2. 情态动词不受主语的人称和数的限制,不随人称和数的改变。

3. 情态动词后可直接+not 构成否定,可放于句首构成一般疑问。

1.can和could的用法

can(could)表示①“能力”、 I can play the guitar.② “许可”you can go now. ③“可能性”Lucy may be here.等。could 为 can 的过去式。④表示请求时,could比can更婉转(属于现在时态范围)。如:Can I use your bike?我可以用你的自行车吗?

[注意] can 和could 只能用于现在时和过去时两种时态,将来时中用 be able to,be able to 所用的时态比can、 could广。另外 can't 可表示否定推测“不可能”。如:

That ______ be Mr Wang. He has gone to Beijing. 那肯定不是王老师,他已经去北京了。

2.may和might的用法

may(might)意为①“可以”,表示说话人同意、许可或请求对方许可May I use your pen?,②也可表示祝愿。 May god bless you!③may表允许用于肯定句中 You may go now.may的否定式为 may not。

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。如:______ I use your pen? 我可以用你的钢笔吗? You may put on more clothes. 你可以多穿衣服。 May you be happy.祝你开心。

Might I borrow some money now?我现在可以借点钱吗? He might be alive. 他可能还活着。 May 和might 表推测,比较小的不太有把握的推测。用于肯定句中。

He may come tomorrow, but I’m not sure.

注意:may构成的一般疑问句避免用yes,you may.以免显得不客气。

May I go now? _ Yes, please./ Please don’t. / 否定No, you can’t.

3.must的用法

must ①意为“必须,应该,一定,准是”,表示说话人认为有必要做某事,命令、要求别人做某事以及对事物的推测。must 用于一般现在时和一般将来时,过去式可用 have to 的过去式代替。如:I ______ finish my work today.我今天必须完成我的工作。②否定式mustn’t表“严禁、禁止 ”含义。You mustn't drive after drinking.你绝不能酒后驾车。

(1)must 和 have to 的区别: must 表示说话人的主观意愿;have to 表示客观需要have to 的否定形式和疑问式要借助助动词do。如:I must do my homework first.我必须首先做家庭作业。It is raining hard outside; I ______ stay at home.外面雨下得很大,我不得不待在家里。

(2)回答must 的提问

①肯定回答:Yes,…must. 如:—Must I go home now?—Yes, you must.

“我必须现在回家吗?” “是的,你必须。”

②否定回答:No,…needn't./No,…don't/doesn't have to. 如:

—Must I go home now? —No, you ______________.“我必须现在回家吗?” “不,没必要。”

(3)must 可以表示肯定推测,意为“一定”。比may 的可能性大如:

The man must be our teacher.那个人一定是我们的老师。

4.need的用法

(1)need 表示“需要,必须”。主要用于否定句和疑问句中,否定形式为needn‘t,表示“没有必要,不必”;need 提问时,肯定回答用must,否定回答用 needn’t。如:

—Need we do some cleaning now? “我们必须现在大扫除吗?”

—Yes, you must. “是的,你们必须。” —No, you needn‘t. “不,你们不必。”

(2)need 还可当做实义动词使用,这时常用结构为need sth/ need to do sth。常用于肯定句中。否定形式和疑问式要借助助动词do的形式。如:I need to learn more. 我需要学习更多。

5.shall和should的用法

shall 用于第一人称的句子中表示提建议或请求;(建议和请求为考点)

should用于各种人称的句子中强调义务或责任“应该”。

如:______ we go out for a walk?我们出去散步好吗?(建议)

You should study hard at school. 你们在学校应该努力学习。(劝告)

6.will和would的用法

Will①情态动词,用于第二人称疑问句时,表示征求意见或提建议。②助动词 构成一般将来时。

would 为 will 的过去式,可用于多种人称,①表示意愿。如:Will you have a little soup?你要不要喝点汤?②would you like sth/to do sth?提出建议与请求。

此外还有情态动词:had better, ought to , have to等等。

[归纳] 情态动词表推测的用法

(1)肯定句中一般用must(一定),may(可能),might/could(也许,或许),其中must表推测的语气最强,其余依次渐弱。如:

The book must be hers. Her name is on it.这本书一定是她的,她的名字在上面。

He must be running.他一定是在跑步。

They may know the way to the library.他们可能知道去图书馆的路。

(2)否定句中一般用can't/couldn't(不可能)。如:

That man can‘t be Mr Li because he has gone to London.那个人不可能是李老师,因为他去伦敦了。

(3)疑问句中用can/could(能)。如:—Can the red sweater be Tom's?—No, it can't. He can't stand red.“这件红毛衣会是吉姆的吗?”“不,不可能。他不能忍受红色。”

[注意] might, could并不是may, can的过去式,而是表示语气较委婉或可能性较小。

⑷情态动词+一般现在时/do 表示对现在发生的事情的推测。如:Whose book is this? It must belong to Lucy. 它一定属于露西的。

情态动词+进行时/be doing 表示对现在正在发生的事情的推测。如:He must be sleeping now.现在他一定正在睡觉。

情态动词+完成时 have done表示对已经(过去)发生的事情的推测。如:Our classroom is very

clean. It must ha

3. may的用法

(1)表示请求、许可, 比can 正式, 如:
