对现在或客观事实的疑问推测，往往用can或could，而不用may/might。

分析：对现在或客观事实的疑问推测，往往用can或could，表示惊异、怀疑、困惑、失望等感情色彩。答案为A。

对过去已发生事情的肯定推测常用 “must/may/might +have + v-ed”，“must+ have + v-ed”意思为“想必、准是、一定是”，语气非常肯定且只能用于肯定句，“may/might+ have + v-ed” 意思为“也许、或许”表示推测的把握不大，只能用于肯定或否定句，不用于疑问句；对过去的否定推测常用 “can/could /may’might not + have + v-ed”，意思为“不可能/可能没做过……”；对过去的疑问推测只用“can/could + have + v-ed”，意思为“可能已经……”。

例16：He _______ have completed his work; otherwise, he wouldn’t be enjoying himself by seaside. (2005北京)

A. should B. must C. wouldn’t D. can’t

分析：根据后一分句判断，前一分句应该表示肯定完成了工作，故用“must+ have + v-ed”意思为“想必、准是、一定是”，语气非常肯定且只能用于肯定句。答案为B。

例17：My sister met him at the Grand Theatre yesterday afternoon, so he _____ your lecture.(上海)

A. couldn’t have attended B. needn’t have attended

C. mustn’t have attended D. shouldn’t have attended

分析：must表推测时，不用于否定，needn’t have +v-ed 表示“本来没有必要”，shouldn’t have +v-ed表示“本来不应该”，“can/could not + have + v-ed” 意思为“不可能做过……”。故答案为A。

例18：--Do you know where David is? I couldn’t find him anywhere.

三、考查情态动词的虚拟用法

例19：―I’ll tell Mary about her new job tomorrow.

--You________ her last week. (2004福建)

A. ought to tell B. would have told C. must tell D. should have told

分析：对过去发生事情的责备或遗憾应用“情态动词+have + v-ed”，据此可排除答案A、C，而would+have +v-ed常用于过去的虚拟语气中，should(ought to)+ have + v-ed”表示本应该做某事而实际上没有做，含有责备的含义。其否定式表示某种行为不该发生但却发生了。故答案为D。

例20：He paid for a seat, when he ______ have entered free. (2005山东)

A. could B. would C. must D. need

分析：“could+ have + v-ed” 用于肯定句中，表示本来能够做成某事的但结果没能做成，含有遗憾的意味，侧重有能力而没能做成。该句意思为：“他花钱买了座位，而他本来可以免费进去的”。答案为A。

例21：You should not have swum in that river. You ____ have been eaten by fish.

分析：前一分句的should not have swum表示责备，后一分句则表明有被鱼吃掉的可能性。“might+ have + v-ed” 用于肯定句中，表示本来有可能做成某事但结果没能做成，含有遗憾的意味，侧重有某种可能性但没能做成。

例22：―Catherine, I have cleaned the room for you.

―Thanks. You ______ it. I could manage it myself. (2005福建)

非谓语动词是英语语法中的重要部分，它包括不定式、动名词和分词。掌握了非谓语动词的用法和特点，可以帮助我们更准确、简洁地表达自己的意思。下面，我们将从不同角度详细讲解非谓语动词，并通过课件的形式生动地展示给大家。

第一部分：不定式

不定式是非谓语动词中的一种形式，由“to + 动词原形”构成。它有时可以用作主语、宾语、表语、定语和状语等不同的句子成分。比如，在下面的句子中，不定式分别充当了不同的句子成分：

1. 主语：To learn a new language is challenging.

2. 宾语：She wants to go shopping.

3. 表语：His dream is to become a famous musician.

4. 定语：She needs a pen to write with.

5. 状语：He left the room to grab a drink.

第二部分：动名词

动名词是非谓语动词中的另一种形式，它由动词的现在分词形式构成，常以-ing结尾。动名词可以用作主语、宾语、表语、定语和状语等不同的句子成分。下面是一些例子：

1. 主语：Singing makes her happy.

2. 宾语：I enjoy playing basketball.

3. 表语：Her favorite activity is dancing.

4. 定语：The running water sounded soothing.

5. 状语：He did his homework while listening to music.

第三部分：分词

分词是非谓语动词中的最后一种形式，它包括现在分词和过去分词。分词可以用作定语和状语。现在分词以-ing结尾，过去分词通常以-ed或-en结尾。以下是一些例子：

1. 定语：The broken window needs to be repaired.

2. 状语：Smiling happily, she greeted her friends.

3. 定语：The stolen wallet has been returned.

4. 状语：Exhausted from work, he fell asleep in the chair.

1. _____ fired, your health care and other benefits will not be immediately cut off.

A. Would you be B. Should you be

解析：答案为B。Should you be fired = If you should be fired。英语中should是一个常用的情态动词，但它可用于条件状语从句中，表示语气较强的假设，意为“万一，竟然”。

2. -What’s the name?

A. Shall B. Would C. Can D. Might

3. John, look at the time. _____ you play the piano at such a late hour?

解析：答案为A。此题考查must的特殊用法。这里must表示与说话人相反的愿望或语气不耐烦，意为“偏偏，偏要”。注意：近几年must表示“偏偏，偏要”这一用法已成为高考的一个热点。

9. You can’t imagine that a well-behaved gentleman _____ be so rude to a lady.

A. might B. need C. should D. would

A. a；不填 B. the；an C. the；the D.不填；the

2. should 的用法。 should 作为情态动词，主要表示“应该”：

Should I open the window?

What should we do now?

You should have told us earlier.

（4） 用于 should like / should love 可视为习语，意为“想要”，其后接名词、代词或不定式：

I should like you to stay here.

I should love to ask you a question.

should用于 can’ t think why／don’t know why／see no reason why：等后面：

I don’t know why you should think that I did it．

我真不知道你凭什么竟会认为这件事是我干的。

I see no reason why you should interfere in their quarrel．

我不明白你有什么理由竟然会介入他们的争吵。

当这种设想与过去的事情有关时则用完成式：

I can’t think why he should have said that it was my fault．

我真不明白他怎么能说这是我的过错。

B 作为一种惯用表达法，should与 what，where，who连用以形象生动地表达惊奇的感情：

What should I find but an enormous spider！

怎么也想不到我看见的竟是一只巨大的蜘蛛！

这种惊奇经常掺杂着令人为难的因素：

Who should come in but his first wife！

怎么也想不到进来的竟是他的前妻！

C should用在 lest后面，有时也用在 in case后面：

1 在书面语中，lest…should结构有时放在表示惧怕或担心的词后面：

He was terrified lest he should slip on the icy rocks．

他害怕在结冰的石块上滑倒。

对过去的动作表示担心时用should+完成式：

她开始担心他出了什么事。

2 lest也可用于目的从句，表示 for fear that（惟恐）：

He dared not spend the money lest someone should ask where he had got it．

他不敢花这笔钱，怕有人问他钱是从哪儿来的。

如上所示这是一种书面形式。

在这种情况下 in case较 lest更常用，后面可跟 should或一般现在时或一般过去时：

in case someone should ask／someone asked

D should 有时用于目的从句以代替 would／could：

He wore a mask so that no one should recognize him．

E 在条件句中用should代替现在时态：

If the pain should return take another of these pills．

F should 还用于颇为正式的间接命令，这种命令不一定是向对方直接发出的：

He ordered that Tom should leave the house．

与下面一句比较一下：

He ordered Tom to leave．

―Yes，you must./No，you needn’t.是的，你必须。/不，没必要。

I will tell you all about it.我愿把事情全部都告诉你。

He won’t go with us.他不愿和我们一起去。

Would you like some coffee？想要点咖啡吗？

用作情态动词时，表示“敢；敢于”，和need一样，也是主要用于疑问句、否定句和条件从句中。

He daren’t speak English before such a crowd，dare he？他在众人面前不敢说英语，是吧？

1.used to表示过去的习惯动作或状态（暗示现在已不如此）。

―Did you use to go there to see your brother？/Used you to go there to see your brother？你过去常去那儿看你兄弟吗？

―Yes，I did（used to）。/No，I didn’t（usedn’t）。是的，经常去。/不，不经常去。

三、用作动词

在日常学习中，很少遇到can用作名词和动词用法，但我们要熟知其意义及其用法，做到熟练掌握，灵活运用!

情态动词can的用法，绝对没你想象得那么简单!

在英语学习中，情态动词是一个很重要的语法点，其中情态动词can的用法比较常见。多数情态动词在用法上会有几点共通之处，只要掌握好较为常见的情态动词，如can、should等的用法，相信大家在学习其它情态动词时就能做到举一反三，轻松不少。

情态动词表示说话人对所说动作的观点,如需要、可能、意愿等。情态动词本身词义不完全,不能单独作谓语动词,必须和实义动词或系动词连用,构成谓语。情态动词can意为“能;会;可以”,其后接动词原形,没有人称和数的变化。

主语+can+动词原形+其他。

例如：He can play football.他会踢足球。

主语+can’t+动词原形+其他。

例如：He can’t play the piano.他不会弹钢琴。

Can+主语+动词原形+其他?

例如：Can he play the piano?他会弹钢琴吗?

Yes, he can.是的,他会。

No, he can't不,他不会。

特殊疑问词+can+主语+动词原形+其他。

例如：What can he do? 他会做什么?

特别提醒：回答can开头的一般疑问句时,通常用“Yes,主语+can.”或“No,主语+can’t.”。有时候说话人为了缓和语气,可以用其他一些词语(如sorry)来作否定回答。

例如：Can he drive?他会开车吗? Sorry,he can’t.对不起,他不会。

情态动词课件 〈十一〉

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。

(2).表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。

(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? 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 A

2. could的用法：

(1).can的过去式，意为“ 能、 会”，表示过去的能力。如：He could write poems when he was 10. 他十岁时就会写诗。

(2). could在疑问句中，表示委婉的语气，此时 could 没有过去式的意思。如:Could you do me a favour? 你能帮我个忙吗?—Could I use your pen? 我能用一下你的钢笔吗? —Yes, you can.可以。(注意回答)

3. may的用法：

(1).表示请求、许可，比can 正式，如：May I borrow your bike? 我可以借你的自行车吗?You may go home now. 现在你可以回家了。

【例题】—_______ I borrow your MP3? —Sure . Here you are. A. May B.Should C.Must D. Would

(2) .表示推测，谈论可能性，意为“ 可能， 或许”，一般用于肯定句中。 如：It may rain tomorrow . 明天可能会下雨。She may be at home. 她可能在家呢.

(3) .may的过去式为might ，表示推测时。可能性低于may。 如：He is away from school. He might be sick.

他离开学校了，可能是他生病了。

(4) . 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!

4. must的用法：

(1).must 表示主观看法，意为“必须、一定”。 如：You must stay here until I come back.在我回来之前你必须呆在这儿。Must I hand in my homework right now? 我必须现在交作业吗?

(2) 其否定形式mustn’t表示“ 一定不要 ” “千万别” “禁止, 不许”. 如：You mustn’t play with fire. 你不许玩火。You mustn’t be late. 你一定不要迟到。

(3)对must引导的疑问句，肯定回答为must，否定回答为needn’t 或 don’t have to .如：—Must I finish my homework?我现在必须完成作业吗?—No, you needn’t.不，你不必。

(4)must表示有把握的推测，用于肯定句。如: The light is on, so he must be at home now.灯亮着，他现在肯定在家。

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’t she?(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)

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? 我还有必要留在这儿吗?—Yes, you must .是的。—No. you needn’t /don’t have to. 不， 你不必。

(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. 我需要马上做这件事。He needs to learn more about the girl.他需要多了解那个女孩。

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。

6. 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。

Where could / can the boy be now ? 那孩子现在能在哪儿呢?

另外，could还常用于表示较客气委婉的看法、提问及用于虚拟语气的结构中。这时候，could就不可以看作是can的.过去式了。而是could自己独特的用法。如：

Could you speak a little slowly ?

您能稍微说慢一点儿吗?

I'm afraid that we couldn't give you any definite answer at this moment .

恐怕我们这时候还无法给予您任何确切的答复。

I could come earlier if asked .

He was able to go to the party yesterday evening in spite of the heavy rain.

----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.

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).

----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.

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.

1. You’re Tom’s good friend, so you must know what he likes best.

2. Your mother must be waiting for you now.

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.

2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。

1.You needn’t come so early.

2. ---- Need I finish the work today?

---- Yes, you must. / No, you needn’t.

3) dare和 need作实义动词用时， 有人称、时态和数的变化。在肯定句中，dare后面常接带to的不定式。在疑问句和否定句中，dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。

1. I dare to swim across this river.

2. He doesn’t dare (to) answer.

3. He needs to finish his homework today.

一、 比较can 和be able to

1)can　could 表示能力;可能 (过去时用could),

只用于现在式和过去式(could)。be able to可以用于各种时态。

they will be able to tell you the news soon. 他很快就能告诉你消息了。

2)只用be able to

a. 位于助动词后。

b. 情态动词后。

c. 表示过去某时刻动作时。

d. 用于句首表示条件。

e. 表示成功地做了某事时，只能用was/were able to， 不能用could。

he was able to flee europe before the war broke out.

he managed to flee europe before the war broke out.

注意：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.

2)在否定，疑问句中表示推测或怀疑。

he couldn't be a bad man.

他不大可能是坏人。

二、比较may和might

1) 表示允许或请求;表示没有把握的推测;may 放在句首，表示祝愿。

if that is the case, we may as well try.

典型例题

peter ___come with us tonight, but he isn't very sure yet.

a. must　b. may　c. can　d. will

答案b. 表可能性只能用may.　此句意可从后半句推出。

三、比较have to和must

3) 在否定结构中： don't have to　表示"不必"

mustn't　表示"禁止"，

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告诉他。

四、must表示推测
