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：

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。

He hasn?t been able to fini sh 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

2)．might

（1）用作may的过去式。

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。

（2）．表示肯定的推测：一定

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）

Will you have some rice?

2）．would

（1）will的过去式，表示过去的意愿和决心。

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。

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）

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。

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 boo ks.

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.

You had better not leave now.

Had I better wait for her?

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

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 mus tn?t. / can?t.（4）can?t 还

可用于固定习语中。She can?t help crying.

2.may 的否定式为may not ，译成“ 可能不”，He may not be at home.

3.（1）mustn?t 表示不许，不可。He mustn?t leave his room.

（2）mustn?t也可用于以may 表示要求时的否定回答中。May I stand here?No, you mustn?t(can?t).

4. （1）nee dn?t 意为“ 不必” 。You needn?t meet him unless you?d like to.

（2）needn?t + have+ 动词的过去分词，表不需要完成但已完成的动作，暗含时间或精力上的浪费。You needn?t have bought it.

5. shouldn?表不应该You shouldn?t feel so unhappy over such little things.

（七）易混淆点

易混点一can 和be able to

两者表示能力时用法相同，但can 只有原形“can” 和过去式“ could ”两种形式，在其他时态中要用be able to 来表示。另外be able to 常常指经过努力，花费了时间和劳力之后才能做到某事。Jim can?t speak English.He could speak English at 5. We?ll be able to see him next week. He has been able to drive. I …m s ure you …ll be able to finish it quickly. We were able to reach the top of the mountain at noon.

易混点二can和may

1. can 和may 均可用来征求意见或许可，意为“可以”，一般可互换

2. can 和may 表示可能性时的区别：

1) 在肯定句中用might，may，must，不用can

2)在疑问句中表示推测用can，不用might，may，must

3)在否定句中用can?t（不可能），不用may，must。That can?t be true.

易混点三may be 和maybe

用法区别常用位置may be may为情态动词，be为动词原形，句中作谓语maybe副词，大概、也许，相当于perhaps位于句首，作状语

He may be wrong , but I?m not sure.

易混点四can’t 和mustn’t.

can’t根据其基本用法可译为：（1）不会，I can?t speak English .（2）不能，We can?t do it now because it?s too dark.（3）不可能，The man can?t be our teacher because he is much younger than our teacher..

mustn’t意为“ 禁止、不许”，用来表达命令，表示强烈的语气。You mustn?t play football in the street. It?s too dangerous.

易混点五must 和have to

must 侧重于个人意志和主观上的必要，还可以在间接引语中表示过去的必要或业务，have to 侧重于客观上的必要，可用于现在时、过去时和将来时I know I must study hard. My brother was very ill, so I had to call the doctor in the mid-night.

易混点六need，dare 的两种用法

need ，dare 作情态动词是，多用于否定句、疑问句中，后接动词原形。You needn?t explain it to me .

Dare you say that again

在肯定句中，它们后边多接动词不定式，此时为实义动词。

Tom needs to fetch the bool for me .

Mary dared to go across the street by herself.

易混点七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

而be used to doing 意为“现在习惯做…”，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.

中考英语情态动词考点归纳与例析

中考英语情态动词考点归纳与例析 【重点讲解】 情态动词表示说话人对某一动作或状态的态度，表示“必须”、“可能”、“应当”、“必要”等。情态动词本身具有一定的意义，但词义不完全，不能独立作谓 语，只能和主要动词一起构成谓语。情态动词没有人称和数的变化，没有非谓语形式。 常见情态动词用法归纳： 1.can和could:can表示能力、可能，只用于一般现在时，过去时用could。 (比较：beableto可以用于多种时态。)但could表示提出委婉的请求，或在否 定，疑问句中表示推测或怀疑时，不表示时态。例如： CouldIhavethetelevisionon?我可以打开电视吗？ Hecouldn’tbeabadman.他不大可能是坏人。 2.may和might表示允许或请求。might表示推测时，不表示时态，只是表示可能性比may小。 3.may(might)have+donesth的意思是“可能已经做了某事”，推测在过去时间里可能 发生的事情。例如： Hemay(might)havebeenhurtseriouslyinthecaraccident. 4.must和haveto都是“必须”的意思。haveto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。haveto有人称、数、时态的变化，而 must只有一种形式。另外，must用在肯定句中表示较有把握的推测，意为“一定”。 否定推测用can't。 5.musthave+donesth表示对过去可能发生的事情的推测，语气较强，具有“肯定”， “谅必”的意思。例如： --Lindahasgonetowork,butherbicycleisstillhere. --Shemusthavegonebybus. 6.should和oughtto都是“应该”的意思，可用于各种人称。 7.oughttohavedonesth/shouldhavedonesth表示本应该做某事，而事实上并没有做。否定句则表示“不该做某事而做了”。另外，oughtto在语气上比should要强。例如：Yououghtto(should)havebeenmorecarefulinthisexperiment. Heoughtnottohavethrowntheoldclothesaway. 8.need和dare既可用作实义动词用，又可用作情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句中。 9.needn'thavedonesth表示“本没必要做某事”。例如： Idressedverywarmlyforthetrip,butIneedn'thavedoneso.Theweatherwas hot. 1

高中英语情态动词精讲与解析

高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought
