初中英语情态动词知识点及经典练习题

情态动词知识点总结：

（一）情态动词的定义

情态动词表示说话人对动作的态度，比如：需要，可能，意愿，猜测或者怀疑等等。

（二）情态动词的特点

1）有一定词义；

2）不受主语人称和数的变化影响；

3）与主要动词的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。

4）否定句中，在情态动词后面加not。

（三）情态动词有：must, shall, should, had better 词形无变化

can(could), may(might), will(would) 词形有变化

need既可以是情态动词，也可以是实义动词，具有双重性。

（四）情态动词的基本用法

1. can (could)

1）表示会做某事，有能力做某事。意思 = be able to 其否定式can’t表示“不能”。在过去时中用could和couldn’t. （即有种能力，尤其是生来具备的能力，此时may和must均不可代替它）。

He can speak English, but he can’t speak Japanese.

= He is able to speak English, but he isn’t able to speak Japanese.

I could smile but I couldn’t speak when I was 2 months old.

= I was able to smile but I wans’t able to speak when I was 2 months old. 区别：1、 can只用于现在时和过去时(could), be able to 可用于各种时态。

They will be able to tell you the news soon.

2、be able to 不与can连用，但可以和其他情态动词或助动词连用。

He may be able to speak English very well some day in the future.

3、用在过去时中，could经常表示能够做某事，事实上不一定去做，而was∕were able to则表示“过去做成了某事”。在否定句中两者可通用。

2）用于征求意见

——Can /Could /May /Might I(we) do sth?

——Yes, you can/may. / Of course you can.

——No(Sorry), you can’t. /mustn’t.

注意：①此处的could和might都不表示过去，只是语气上的委婉，不用作回答。

②否定回答中，表示对他人造成一定伤害或影响，或表示违反了某种规定或法律时，

用mustn’t较好。

e.g. ——Could I take the book out of the library? ——Sorry, you mustn’t. ——May I smoke here? ——I’m afraid you mustn’t.

③表示过去能力时，could 提问，只能用could回答。

e.g. ——Could you ride a bike when you were 4 years old? ——No, I couldn’t.

3）表提出意见或请求

Can/Could you (please) do sth? = Would you (please) do sth? （此句型中some 不变any）

e.g. Could you please give me a hand?

Would you please pass me some salt?

4）表示允许或承诺 =may e.g. OK. You can /may come and find me at any time tomorrow.

5）表示有一定把握的推测，用于否定句和疑问句。此时can’t译为“不可能” 肯定句用must。表示没有把握的推测，用may /might。

e.g. —— The window is broken. Who did it?

—— It may be Mary.

—— It can’t be Mary. The window is in the men’s toilet.

—— Can it be anyone else?

—— Then, it must be Bob. I saw him go into the toilet just now. He can’t (couldn’t) have enough money for a new car. 他不可能有足够的钱买新车。

【例题】—I think Miss Gao must be in the library. She said she would go there.—No. She __be there, I have just been there. A.can’t B.mustn’t C.needn’t D.wouldn’t

【解析】根据下文“我刚去过那儿”可知，应为“不可能”，can’t表示推测[答案] A

2. may (might)

may 表示“可以，可能”，否定形式may not，表示“不可以”。

1）表示没有把握的推测，“可能，也许”。可以指过去时间，也可以指现在时间，但语气更加不肯定。

e.g. He may have a lot of work to do. = Maybe he has a lot of work to do. You may be right. = Maybe you are right.

2）表示请求 “我可以„„吗？” 表示请求、许可，比can正式

e.g. You may /can go now. ——May I use your pen?

——Yes, you may. / Yes, please. / Go ahead.

——No, you can’t. / mustn’t.

在回答以may引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly. / Please don’t ./ You’d better not. / No, you mustn’t.等，以免显得太严峻或不客气。

3）、表示希望、祈求、祝愿，常可译为“祝愿”。通常是用may +主+V例如：May you have a good time.祝你过得愉快。May you be happy!祝你幸福！May you succeed！祝你成功！

3. must

must 表示“必须，肯定，一定”，否定形式mustn’t = must not表示“禁止”。

1）表示必须，意思同have to

e.g. ——Must I do it now?

——Yes, you must.

——No, you don’t have to. / No, you needn’t. (注意：否定回答不用mustn’t) Children mustn’t play on the road because it’s too dangerous. (mustn’t只表“禁止”)

He doesn’t have to go away from here.

=He needn’t leave here.

区别：①must表达主观意愿的“必须”，have to表达客观上或按道理说“不得不”。 e.g. I must study hard.

It’s too late. I have to go now.

②must 没有人称和时态的变化，而have to有。

e.g. He had to walk back home because he lost all his money.

Mom will be away for a week, so we will have to do the cooking by ourselves. 2）表示有把握的肯定句中的推测，“肯定，一定”，只用于肯定句。

He must be ill. He looks so pale. 他准是病了。他的脸色苍白。

注意其反意问句的构成形式：

当must表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。如： She must have seen the film before，hasn’tshe?(注意反意疑问句的后半部分)

You must have met uncle Wang in the shop yesterday，didn’t you? (注意反意疑问句的后半部分)

4.need

need 表示“需要”，否定形式needn’t = need not “不必、不需要”

1)、作情态动词，仅用于否定句和疑问句。

e.g. He needn’t go home early yesterday. = He didn’t need/have to go home early yesterday.

Need I call him right now? ——Yes, you must.(注意：肯定回答不用need) ——No, you needn’t. /No, you don’t have to.

2）、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：need sth./sb.

need to do sth. 否定形式don’t need to = don’t have to 表示“不必” e.g. I need some help.

He needed to go home early yesterday. Do I need to call him right now? ——Yes, you do. / ——No, you don’t. 如果是物作主语，一般用need doing与need to be done这种情况下应注意两点：

①.主动形式的动名词doing具有被动的含义；②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如：. The door needs painting. = The door needs to be painted.那扇门需要油漆一下。Your car needs mending. = Your car needs to be repaired.你的车需要维修了。

3）、 need 作名词

be in (great) need of sth = need sth (badly) “非常需要某物”

meet the need “满足需要（需求）”

there is/was no need (for sb) to do sth “某人没必要做某事”

5. dare的用法：

dare意为“敢、敢于”,用法近似于need，有两种词性：

（1）dare作为情态动词，多用于否定句、疑问句或条件句中，无第三人称单数形式，只有一般现在时和一般过去时。如：Dare he tell them what he knows?他敢告诉他们所知道的情况吗？I daren’t ask her – will you do it for me?我可不敢问她，你能帮我问问吗？

（2）dare作为实义动词，此时有人称、数及时态的变化。如：He doesn’t dare to break his promise.他不敢食言。

注意：在口语中，dare的各种形式常与不带to的不定式连用。如：Do you dare tell her what I said?

你敢告诉她我说的话吗？I didn’t dare look at him.我不敢看他

归纳：need和dare的用法

1、need和dare既可用作情态动词，也可用作实义动词。用作情态动词时，通常不用于肯定句而主要用于否定句和疑问句。用作实义动词时，可用于各种句式。

2、其他用法：I dare say„为固定习语，不是“我敢说”而是“我想”。

I dare day he’ll come again. 我想他会再来的。

Needn’t have done:表示本没必要做而做了

6. shall的用法：

1）表征询意见，用于第一、第三人称疑问句。

Shall I get some tea? 我给你点茶好吗？

Shall the boy wait outside? 让那男孩在外面等吗？

2）表说话人的意愿，有“命令、允诺、警告、决心”等意思，用于第二、第三人称陈述句。 You shall do as I say. 按我说的做。（命令）

You shall have my answer tomorrow. 你明天可以得到我的答复。（允诺）

He shall be sorry for it one day, I tell you. 有一天他会后悔的，我告诉你。（警告）

Nothing shall stop us from carrying out the plan. 什么也不能阻止我们执行这项计划。（决心）归纳：在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。

(1).用“Let's do...”来提出建议。如：Let's go for a walk after supper.

(2).用“What/How about...?”来提出建议；about后接名词或动词ing形式。如：What about/How about a drink? What about/How about taking Tom with us?

(3).用“Why not...?”来提出建议，表示“何不„„”not面后接动词原形。“Why not...?”实际上是“Why don't you/we...?”的简略形式。如：Why not meet at the school gate at eight? Why don't we stay here another day?

(4).用“Would you like...?”来提出建议，意思是“你想要„„吗?”Would you like后可接名词或不定式。如：Would you like a cup of tea? Would you like to go and see her?

因此，如果我们说：“去游泳好吗?”英语中可有这样几种表达法：Shall we go for a swim? Let's go for a swim，shall we? What about/How about going swimming? Why not go for a swim? Would you like to go for a swim? What do you think of going for a swim?

6、 will的用法

1）、表意愿，用于各种人称陈述句。“愿意”

I will do anything for you. 我愿为你做任何事。

2）、表请求，用于疑问句。

Will you close the window? It’s a bit cold. 请你把窗户关上好吗？有点冷。 Won’t you drink some more coffee? 再来一点咖啡好吗？

注意：

1、will在there be句型中的形式及其句式变换。

由于“一般将来时”的结构可以用“will+动词原形”来表示，所以there be句型的一般将来时的形式就是there will be。（一定不能说there will have）例如：There are many

students in our school.→There will be many students in our school. There will be a sports meeting next week.一定不能说：There will have a sports meeting next week.

2、will与be going to do something区别：

①. be going to表示近期、眼下就要发生的事情，will表示的将来时间则较远一些，如：He is going to write a letter tonight. He will write a book one day.

②. be going to表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。He is seriously ill. He is going to die. He will be twenty years old. ③. be going to含有“计划，准备”的意思，而will则没有这个意思，如：She is going to lend us her book.

He will be here in half an hour.

④.在有条件从句的主句中，一般不用be going to,而多用will,如：If any beasts comes at you, I'll stay with you and help you.

7. should的用法

1）、表义务。意为“应该”（某件事宜于做），用于各种人称。否定形式 shouldn’t = should not表示“不应该”

You should be polite to your teachers. 你对老师应该有礼貌。

2）、表推测，意为“想必一定、照说应该、估计”等。

The film should be very good as it is starring first-class actors.

这部新电影是一流演员主演的，估计拍得很好。

They should be home by now. 照说他们现在应当已经到家了。

8.would的用法

1）表意愿

I said I would do anything for you. 我说过我愿意为你做任何事。

2）表委婉地提出请求、建议或看法。

常见句型：①表请求Would you please do„? ——OK„. / Sorry, „.

②Would you like sth? ——Yes, please. / No, thanks.

Would you like to do sth? ——I’d love to.

——I’d love to, but„.

(注意：以上句型中，some不变any)

9. ought to

1）表义务，意为“应该”（因责任、义务等该做），口气比should稍重。

You oughtn’t to smoke so much. 你不应该抽这么多烟。

2）表推测，暗含很大的可能，语气较弱。

There’s a fine sunset; it ought to be a fine day tomorrow. 今天有晚霞，明天应该是个好天。

10、used to

表示过去的习惯动作或状态，现在不复发生或存在。疑问式和否定式有两种。

I usedn’t (didn’t use) to smoke. 我过去不抽烟。

Used you (Did you use) to go to school on foot? 你过去常步行去学校吗？

11、had better do表示“最好是做„„”，否定形式 had better not do

e.g. You’d better not drink so much coffee.

He must be ill. He looks so pale. 他准是病了。他的脸色苍白。

注意其反意问句的构成形式：

当must表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。如： She must have seen the film before，hasn’tshe?(注意反意疑问句的后半部分)

You must have met uncle Wang in the shop yesterday，didn’t you? (注意反意疑问句的后半部分)

4、need

need 表示“需要”，否定形式needn’t = need not “不必、不需要”

（1)、作情态动词，仅用于否定句和疑问句。

e.g. He needn’t go home early yesterday. = He didn’t need/have to go home early yesterday.

Need I call him right now? ——Yes, you must.(注意：肯定回答不用need) ——No, you needn’t. /No, you don’t have to.

（2）、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：need sth./sb.

need to do sth. 否定形式don’t need to = don’t have to 表示“不必” e.g. I need some help.

He needed to go home early yesterday. Do I need to call him right now? ——Yes, you do. / ——No, you don’t. 如果是物作主语，一般用need doing与need to be done这种情况下应注意两点： ①.主动形式的动名词doing具有被动的含义；②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如：. The door needs painting. = The door needs to be painted.那扇门需要油漆一下。Your car needs mending. = Your car needs to be repaired.你的车需要维修了。

（3）、 need 作名词

be in (great) need of sth = need sth (badly) “非常需要某物”

meet the need “满足需要（需求）”

there is/was no need (for sb) to do sth “某人没必要做某事”

5. dare的用法：

dare意为“敢、敢于”,用法近似于need，有两种词性：

（2）dare作为实义动词，此时有人称、数及时态的变化。如：He doesn’t dare to break his promise.他不敢食言。

注意：在口语中，dare的各种形式常与不带to的不定式连用。如：Do you dare tell her what I said?

你敢告诉她我说的话吗？I didn’t dare look at him.我不敢看他

归纳：need和dare的用法

2、其他用法：I dare say„为固定习语，不是“我敢说”而是“我想”。

I dare day he’ll come again. 我想他会再来的。

Needn’t have done:表示本没必要做而做了

6. shall的用法：

（1）表征询意见，用于第一、第三人称疑问句。

Shall I get some tea? 我给你点茶好吗？

Shall the boy wait outside? 让那男孩在外面等吗？

（2）表说话人的意愿，有“命令、允诺、警告、决心”等意思，用于第二、第三人称陈述句。

You shall do as I say.按我说的做。（命令）

You shall have my answer tomorrow.你明天可以得到我的答复。（允诺）

He shall be sorry for it one day, I tell you.有一天他会后悔的，我告诉你。（警告） Nothing shall stop us from carrying out the plan.什么也不能阻止我们执行这项计划。（决心）归纳：在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。

(1).用“Let's do...”来提出建议。如：Let's go for a walk after supper.

(2).用“What/How about...?”来提出建议；about后接名词或动词ing形式。如：What about/How about a drink? What about/How about taking Tom with us?

(4).用“Would you like...?”来提出建议，意思是“你想要„„吗?”Would you like后可接名词或不定式。如：Would you like a cup of tea? Would you like to go and see her?

6、 will的用法

（1）、表意愿，用于各种人称陈述句。“愿意”

I will do anything for you.我愿为你做任何事。

（2）、表请求，用于疑问句。

Will you close the window? It’s a bit cold.请你把窗户关上好吗？有点冷。 Won’t you drink some more coffee?再来一点咖啡好吗？

注意：

1、will在there be句型中的形式及其句式变换。

由于“一般将来时”的结构可以用“will+动词原形”来表示，所以there be句型的一般将来时的形式就是there will be。（一定不能说there will have）例如：There are many students in our school.→There will be many students in our school. There will be a sports meeting next week.一定不能说：There will have a sports meeting next week.

2、will与be going to do something区别：

①. be going to表示近期、眼下就要发生的事情，will表示的将来时间则较远一些，如：He is going to write a letter tonight. He will write a book one day.

He will be here in half an hour.

④.在有条件从句的主句中，一般不用be going to,而多用will,如：If any beasts comes at you, I'll stay with you and help you.

7. should的用法

（1）、表义务。意为“应该”（某件事宜于做），用于各种人称。否定形式 shouldn’t = should not表示“不应该”

You should be polite to your teachers. 你对老师应该有礼貌。

（2）、表推测，意为“想必一定、照说应该、估计”等。

The film should be very good as it is starring first-class actors.

这部新电影是一流演员主演的，估计拍得很好。

They should be home by now. 照说他们现在应当已经到家了。

8.would的用法

（1）表意愿

I said I would do anything for you. 我说过我愿意为你做任何事。

（2）表委婉地提出请求、建议或看法。

常见句型：①表请求Would you please do„? ——OK„. / Sorry, „.

②Would you like sth? ——Yes, please. / No, thanks.

Would you like to do sth? ——I’d love to.

——I’d love to, but„.

(注意：以上句型中，some不变any)

9. ought to

（1）表义务，意为“应该”（因责任、义务等该做），口气比should稍重。

You oughtn’t to smoke so much.你不应该抽这么多烟。

（2）表推测，暗含很大的可能，语气较弱。

There’s a fine sunset; it ought to be a fine day tomorrow.今天有晚霞，明天应该是个好天。

10、used to

表示过去的习惯动作或状态，现在不复发生或存在。疑问式和否定式有两种。

I usedn’t (didn’t use) to smoke.我过去不抽烟。

Used you (Did you use) to go to school on foot?你过去常步行去学校吗？

11、had better do表示“最好是做„„”，否定形式 had better not do

e.g. You’d better not drink so much coffee.

区别：It’s better for you to do more exercise and not to have so much junk foo 归纳：一、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，如：He can’t be ill. He is playing chess with Tom.他不可能病了，他正和Tom下棋呢。

初中语法情态动词典型例题篇四：初中英语情态动词讲解练习及答案

情态动词

一、考点、热点回顾

【词汇辨析】

1. sometimes/ some times/sometime/ some time:

sometimes: “有时”=at times. He is sometimes late for school.

some times: “几次” I have been to Nanjing some times.

sometime: “某一时刻” I bought it sometime last spring.

We’ll meet again sometime next week.

some time: “一段时间” We have to stay here for some time.

2. many/ much/ a few/ a little/ few/ little

(1)many修饰可数名词，much修饰不可数名词；都表示许多。例如：

许多书许多牛奶

(2)a few和a little都表示"有一点儿"，侧重于肯定，相当于"some"，但a few修饰可数名词，

a little修饰不可数名词，例如：

He has a few friends in London.

---Would you like some coffee?

---Yes, just a little.

(3)few和little表示"几乎没有"，侧重否定。few后接可数名词，little后接不可数名词。例如：He is a strange man. He has few words.

Hurry up, there is little time left.

【固定搭配】加-ing

be busy doing sth. 忙于做„„ eg: Mother is busy cooking.

look forward to + doing sth. 期待做„„ eg: Tom looks forward to seeing his father again. Thank you for (doing) sth. 为了„感谢你 eg: Thank you for your help.

愉快地做某事 eg: I had great fun playing in the water.

=have a good time doing sth eg: I had a good time playing in the water.

have problem/trouble/difficulty (in)doing sth.做某事有困难

eg: I have difficulty finishing my homework in 2 hours.

【情态动词】又叫情态助动词。它们具有以下特点：

⑴ 它们必须与其他动词连用，即：情态动词＋动词原形

表示说话人对所述动作的看法，如需要、可能、意愿或怀疑等。

⑵ 绝大多数情态动词没有人称和数的变化，即第三人称单数不加-s

（以be和have 开头的情态动词短语除外）。

⑶ 在意义上，情态动词具有“多义性”。

例：can既可表示能力，又可表示可能、允许等意义。

【情态动词的基本用法】

1. can的基本用法：

⑴ 表示体力或智力上的能力，即“能够，会”，可与be able to转换。

例：He can speak English. = He is able to speak English.

—Can you play basketball?

— No, I can’t.

如果表示将来具备的能力，要用will be able to。

例：If I have a good sleep, I will be able to do the problem.

⑵ 表示许可，主要用于口语，书面语一般用may。

例：—Can we go home now, please?

— No, you can’t.

You can only smoke in this room.

You can’t keep the library books for more than a month.

⑶ 表示“可能”，与may同义，但一般用在疑问句中。

例：What can he possibly want?

在否定句中，否定形式can’t表示推测“不大可能”。

例：Anybody can make mistakes.

The news can’t be true.

与第一、二人称连用时，还可以就可能的解决问题的方式或可能的行为提出建议。在这里，也可用could使语气婉转。

例：Can / Could we meet again next week? 下周我们可以再见面吗？

—What shall we do? 我们怎么办呢？

— We can / could try asking Lucy for help. ——我们可以请露茜帮忙试试看。

You can / could help me with the cooking. 你可以帮我做饭。

2. may的基本用法:

⑴ 表示“许可”，用can比较口语化。

例：You may / can come if you wish. 如果你想来，你就来。

You may not pick flowers in this park. 本公园内不许摘花。

（may not表示按规定不许可，如果用mustn’t则表示说话人不许可。）

我可以在这里抽烟吗？

—

mustn’t表示明确的禁止。）

⑵ 肯定句中表示推测，“可能”。

例：It may rain tomorrow. 明天可能会下雨。

The news may not be true. 这个消息可能不会是真的。

注意：如果

例：

Can it be true? 那会是真的吗？ Who can he be? 他究竟是谁呢？

⑶ 【注意】：„„？

——No

3. must的基本用法:

⑴ 表示必须，强调说话人的主观意志。

例：I must go now, or I’ll be late.

ten o’clock.

【注意】：表示“必须“时，must

,而不是mustn’t。

也就是：—Must I/we do it now？

—

例：—Must I go with them?

—, you

⑵ 表示推测，一般只用于肯定陈述句,表示非常肯定。

例：She didn’t look at me. She must be angry. 她不朝我看，一定是生气了。

He is good at English. He must know the word. 他英语好，准知道这个词。

You must be Mr. Jones. 想必您就是琼斯先生吧。

4. have to的基本用法：

have to可视为情态动词，但它与其他情态动词在用法上稍有不同。其他情态动词没有人称和数的变化，而have to却有人称和数的变化，要视主语的不同而变化。

例：I / You / We / They have to….

He / She / It to….

You don’t to….

Does she to…?

”。

和must不同之处：must强调主观需要

have to强调客观需要。

例：Sorry, I have to leave now. 对不起，现在我得走了。

I我得去参加一个会议。

Will hework deep into the night? 他将不得不工作到深夜吗？ 5. need的基本用法： need的基本词义是“需要”，

⑴ need用作情态动词时，只用于否定句和疑问句。它只有一种形式，后接动词原形。

例：I don’t believe you need worry. 我相信你没有必要焦急。

—Need we go so soon? 我们需要这么早就去吗？

— Yes, we . 是的，必须。／不，不必。

So I needn’t tell him, need I? 所以我不需要告诉他，对吧？

请比较以下两句话的不同意思：

你没有必要买那件外衣。（你还没买）

You the coat. 你没有必要买这件外衣的。（而你却买了）

【注意】：I/we„„？

—，—

⑵ need

如果

人作主语，一般后接带to的动词不定式。即

如果物作主语

例如：I need to look up this word in the dictionary.

My watch needs /我的手表需要修理了。

We don’t need to work today. (= We needn’t work today.)

Does he need to go right now? (= Need he go right now?)

6. had better的基本用法：

had better常略作。现代语法认为它是一个助动词，因为它后接不带to的动词不定式。

。

例：You’d better get some sleep. 你最好睡一会儿。

You’d better not do that again. 你最好别再做那件事。

What had we better do now? 我们现在怎么做才好呢？

Hadn’t we better tell her the truth?

我们是否最好不告诉她真相?

7. could, should, would, might表示推测：

①. must多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”。

如: You have worked hard all day. You must be tired. 你已辛苦工作一整天了,一定累了。

The book must be his. His name is on the cover. 这本书一定是他的,封面上写着他的名字。

【注意】 must不表推测时,在肯定句中意思为“必须(强调内在的职责)”,在否定句中意思为“不许、禁止”,以它开头的疑问句否定回答常用needn’t或don’t (doesn’t) have to。

如:We must obey the traffic rules. 我们必须遵守交通规则。

Cars mustn’t be parked here. 此处严禁停车。

—Must we hand in the papers this week? 我们必须本星期交论文吗?

—No, you needn’t. 不,你们不必(本星期交)。

②. can / could多用于否定句、疑问句或感叹句中表示推测、怀疑,两者在时间上没有差别。用can时不相信的程度更强一些,

如:The man under the tree can’t be Tom. He’s gone to England. 这个人不可能是Tom,他已经去英国了。 Can it be true that he was fooled by a five-year-old boy? 他被一个五岁的孩子愚弄了,这能是真的吗? Could this be an excuse? 这会不会是个借口?

How can you be so careless! 你怎么这样粗心!

③.may / might多用来表示把握性不大的推测,意思为“也许、可能”, might比may的把握性更小一些。

(注意区分“不可能”与“可能不”在把握性大小上的差异。) 如:Mr. Wang may know Professor Li’s telephone number.王先生也许知道李教授的电话号码。 This 这可能就是汤姆一直在找的钥匙。

She be there today. 今天她可能不在那儿。

6. B.这组对话的意思是："我可以知道您的英文名字吗""可以，海伦。H-E-L-E-N."该题测试情态动词的用法。"请求对方许可"时，常用 May I （we）„。

7. C.这组对话的意思是："那边的那个男生是谁？是约翰吗？""那不可能是他，约翰个子高些。"该题测试情态动词的用法。表示很肯定的否定推测时，用can't.

8. B.这组对话的意思是："杰伊，你会扔飞盘吗？""会，小菜一碟。"该题测试情态动词的用法。一般说来，以情态动词can开头的问句，肯定回答用can；否定回答用can't. 英语情态动词：

9. A.此题易误选为B或C.这是因为受了思维定势的影响引起的，因为前面句子中的must这个词，许多人就想当然地选择了B项。其实，这里应该选择A项，句意为："你必须每月回来一次。""好的，我会的。"

10. C.maybe是副词，意为"可能；也许"，在句中作状语。may be是两个不同的词，其中，may是情态动词，be是连系动词，在句中作谓语。

11. A.needn't表示"没有必要"；may意为"可以".

12. A.考查情态动词。由后文"但他还不能肯定"可知，他"可能会"来，所以选A.can表示推测的"可能"，多用于否定句或疑问句中，must是有把握的肯定推测，"一定".

13. A.考查情态动词。mustn't千万不，绝不能，一定不要；can't不能；shouldn't不应该；needn't不必要。

英语情态动词：

14. D.考查情态动词。请求允许用may或can.

15. C.考查情态动词。否定回答must，表示"不必"用needn't，排除A和B.又表示允许"可以"，用may或can，所以A正确。若用must与前面needn't相矛盾。

初中语法情态动词典型例题篇六：初中英语语法专项习题11.情态动词

情态动词讲义

I. 情态动词的语法特征

情态动词本身虽有词义，但只表示说话人的看法，命令，准许等；不能单独作谓语，须与实义动词构成谓语

1）情态动词除ought to，have to， used to外，其它情态动词后面只能接不带to 的不定式。

2）情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。

3）情态动词没有非谓语形式，即没有不定式to，分词-ing,-ed等形式。

4）情态动词类别：can/cannot/can not/can’t, may/may not, must/ mustn’t, shall/shall not/ shan’t, should/ shouldn’t, ought to/ oughtn’t to, will/ won’t , would/ wouldn’t. need/ needn’t, dare/daren’t, used to/ usedn’t to/ didn’t use to, have to/ don’t have to, had better/ had better not, would rather/ would rather not II. 一些容易混淆的用法

1. 比较can 和be able to

1）can/could 表示能力(born ability, learned ability), 只用于现在式和过去式(could)。

be able to可以用于多种时态。

2）只用be able to

表示经过努力或在一定条件下设法成功地做了某事时，而非能力，只能用was/were able to，不能用could。-----managed to do sth./ succeeded in doing sth.

He was able to flee Europe before the war broke out.

= He managed to flee Europe before the war broke out.

After two years of hard work, he was able to speak English.

Although the driver was badly hurt, he was able to explain what had happened.

With the help of the firemen, they were able to leave the burning house.

3) could不表示时态

(1) 提出委婉的请求，（注意在回答中不可用could）。

--- Could I have the television on?

--- Yes, you can. / No, you can't.

II. 比较have to和must

1) 两词都是'必须'的意思，have to 表示客观的需要， must 表示说话人主观上的看法，既主观上的必要。 My brother was very ill, so I had to call the doctor in the middle of the night.

我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事)

I want to take more exercise, so I must walk to school every day.

2） must 表示必须，必要，一种义务，责任，职责,命令等语气

e.g. We must obey the school regulations. You must respect the old.

You must come here early tomorrow. I am afraid I must be leaving.

We must stay home, mustn’t we?

3）表示必然，必定,不可避免的结果 Man must die.

表示固执，一定要，坚持要

e.g. Our three-year-old boy must do the opposite to what we ordered.

Why must you interrupt me now and then while I am speaking.

Must you shout so loudly?

表示过去的不巧，偏偏

e.g. Just when I was busy, the neighbor must come and chat.

As I was sitting down to dinner, the telephone must ring.

4）have to有人称、数、时态的变化，而must只有一种形式。

e.g. He had to look after his sister yesterday.

You will have to go there alone.

5） must 问句的回答

e.g. Must I wait until they come?

---Yes, you must.

--No, you needn’t./ don’t have to/ don’t need to

Must we hand in our English exercise books today?

----_____________________. / ____________________

6）在否定结构中： don't have to 表示"不必"

mustn't 表示"禁止，不允许"，带有很强的语气

e.g. You don't have to tell him about it. 你不一定要把此事告诉他。

You mustn't tell him about it. 你一定不要把这件事

Cars mustn’t be parked here.

III. may 表示给予许可

1) You may sit here.

May I borrow your books?

Might I have your telephone number?

2) can/could 和 may/might

. can和 may都可表示请求，或给与许可。Can 语气一般，could/may 比较礼貌，常用。对于can/could的回答,一般是can/can’t,不可用could，而对may的回答，则是may/may not。

----Could I use your legtop?

----Yes, of course you can./ Sorry, I am afraid you can’t .

---May I leave the classroom?

---Yes, you may. / No, you mustn’t/you may not/ you don’t have to.

IV. 情态动词can, could, may, might, must表示推测的用法

He might be at home.

It may have drizzled during the night.

Philip may (might) have been hurt seriously in the car accident.

I should advise you not to do that. 我倒是劝你别这样做。

4） should用于引导的条件从句中，表示一件事听起来可能性很小，相当于“万一”

If you should change your mind, please let us know.

Take a thick coat in case it should get/ gets cold.

5) 用于动词ask, advise, command, demand, insist, intend, recommend, request, require, suggest, urge, order等之后的从句里，表示命令，忠告，要求，建议， (should)+ do / be done.

完形填空的答案：

1. B。在听、说、读、写四个学习环节中，学英语口语最好的方法只能是“说”才合乎实际。

2. D。宾语的动作由别人来完成时，补足语要用过去分词。

3. D。“说不清，道不明”，听的人自然不 “明白或理解”说的是什么。

4. A。这四个词都有“说”的意思，say着重说的内容，talk 强调两个人之间说话，tell着重把一件事情传给别人，speak 着重说某种语言。“说得太快”指说话的内容而言，因此，选say。

5. A。“保持幽默感”与“嘲笑错误”是条件与结果的关系，所以本句是个条件状语从句。when和since引导时间状语从句，although 引导让步状语从句，只有if引导条件状语从句。

6. B。make a mistake 是个固定词组，意思是“犯错误”。

7. A。laugh at是个固定词组，意思是“嘲笑”。

8. B。“嘲笑……”与“愤怒……”相比较时，要用形容词比较级。good和well是原级，best是最高级。

9. B。“笑话你的错误或向你发脾气”与“不理解说的是什么”是结果与原因的关系，所以该句是个原因状语从句。unless与as long as引导条件状语从句，as soon as引导时间状语从句，只有 because引导原因状语从句。(from

10. C。选sad 和 happy 不符合上下文语境，也不合逻辑。如选worry，意思上讲得通，英语中却没有 worry of 这个词组，要改成 worry about才对

初中语法情态动词典型例题篇八：人教版新目标初中英语语法情态动词知识考点试题详解

初中英语语法情态动词知识考点试题详解情态动词用法归纳

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.

知识梳理

情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没哟人称和数的变化，情态动词后必须跟动词原形。

考点一 can ，may， must 等情态动词在陈述句中的用法

1. can 的用法

（1）表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may 和must 均不可代替它。如：

She can swim fast, but I can’t . 她能游得很快，但我不能。

I can see with my eyes. 我用眼睛看。

I can finish it in an hour. 我能在一小时后完成它。

（3）表示许可，常在口语中。如：

You can use my dictionary. 你可以用我的字典。

（4）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? 这个消息会是真的吗？

----Can it be our teacher?

那个人有可能是我们老师吗？

----No, it can’t be our teacher. He is on a visit to the Great Wall. 不可能。咱们老师正在游览长城呢。

例 --- I think Miss Gao must be in the library. She said she would go there. ----- No. She __ be there, I have just been there.

A.can’t B.mustn’t C.needn’t D.wouldn’t

He could write poems when he was 10. 他十岁时就会写诗。
