情态动词有一定的词义, 表示某种感情或语气, 是不完全动词, 不能单独作谓语, 需和实义动词一起构成谓语. 常见的情态动词有: can / could, may / might, must, shall / should, will / would, need, ought to, dare / dared等

一.may / might的用法:

1.表示?可以?, 即表示说话人许可或请求许可

a. You may take it away.

b. May I come in ?

2.表示?可能, 也许? (在疑问句中通常不用may / might, 而用likely, do you think, can等表示?是否可能, 会不会?的意思)

a. He may come today.

b. Is it likely to rain ?

c. Do you think the train will be late ?

d. Can the news be true ?这消息会是真的吗?

3.在提建议时, 可用May I

a. May I carry your bag ?

b. May I make a suggestion ?

二.can / could的用法:

1.表示许可或请求许可, 相当于may. 但can比may用得更广泛. can不仅表示说话人同意, 准许, 还可以表示客观条件许可. may通常只表示说话人同意或准许

a. The class is over. You can go home now.

b. You can go there tomorrow.

c. Can I borrow your car for today ?

2.在提建议时, 可用Can I / you

a. Can I buy you a drink ?

3.表示?会, 能?, 相当于be able to

a. He can speak English.

b. Can you play tennis ?

c. Little Tom can?t move the big box.

4.在疑问句中表示怀疑, 不确定或不会有的情况, 即?否定的推测?

a. Can it be true ? 这是真的吗?

b. Can it be true that he has passed the exam ? 他真的通过考试了吗?

5.can?t / couldn?t在陈述句中可表示?肯定不, 一定不?的意思

a. He can?t be in the room right now.

b. It can?t have rained last night, for the ground is dry.

6.can?t / couldn?t help doing sth表示?不得不,忍不住做某事?

a. People couldn?t help laughing at the foolish emperor.

7.can / be able to do的区别:

①.be able to可用于各种时态, 而can只有现在时can和过去时could

②.be able to可以和另一个不完全动词连用, 如should be able to (应该能够), must be able to (必须能够)等, 而can则不可以这样用

③.强调?能力?时, 多用be able to

a. The patient was soon able to sit up and read.

④.can可用于人或其他事物作主语的句子中; be able to只用于有生命的名词或代词作主语的句子中

三.must的用法:

1.表示?必须?, 它的否定形式是need not / needn?t, 而不是must not / mustn?t, mustn?t表示禁止或不许做某事

a. You must set off at once.

b. You needn?t tell John about it.

c. You mustn?t play with fire.

2.表示?肯定是, 一定是?的推测意义; 与此对应, 表示?肯定不,一定不?用can?t, 而不用mustn?t

a. You must be very tired now.

b. If he had really been there, I must have seen him.

c. He must have gone away. We don?t see him anywhere.

3.must / have to的区别:

①.must / have to一般可以通用, 但must侧重于说话人主观上的看法, 即?说话人认为必须?; have to侧重于客观上的需要, 含有?客观上不得不?之意

a. If the person is not breathing, you must try to start his breathing.

b. You must / have to study with a teacher if you want to know how to do first aid.

②.must没有时态的变化, 一般用于表示现在或将来; have to有时态的变化, 可用于过去, 现在, 将来各种时态

a. We must study hard when we are young.

b. I think she must remain in hospital for a week.

c. We had to stay there for a whole day because of the rain.

d. We have to practise a lot if we want to speak English well.

e. The situation has changed; we will have to change our plan.

③.它们的否定式mustn?t / not have to有很大的不同: mustn?t表示?不要(做某事)?, 有禁止之意; not have to表示?不必要(做某事)?, 含有?客观上无此必要?之意

a. You mustn?t move a person if he is badly hurt.

b. You don?t have to be a doctor to do first aid.

四.would的用法:

1.表示主观意志和愿望, 即?愿意,想要?

b. He should have arrived in Nanjing by this time.

3.should / ought to的区别:

should / ought to一般可以通用. should侧重于说话人主观上的看法, 有时含有劝告, 建议的口气, 即 ?按我的想法应该如何?; ought to语气更强, 强调?有责任, 有义务做某事?或者 ?按道理应该如何?

a. ?I will start the work at once. I think you should start at once.?

b. ?I will start the work tomorrow. No. You ought to start at once.?

The little girl__________to the forest .

A?didn't?dare?goB?dared?not?to?go?C?dared?not?go?D?dares?to?go.

我觉得四个选项都对……T?T

答：不是四项都对，但确实有争议。

析：本题考dare这个动词的两种不同用法。

作情态动词，它和can类情态动词一样，后跟动词原形，否定直接加not后再跟动词原形。疑问句直接将它提到主语的前面，多用于否定句和疑问句(以及条件状语从句中）：

He ~ not tell us.

他不敢告诉我们

D~ he fight?.

他敢打架 [打仗] 吗?

How ~ you [he] say such a thing?.

你[他]怎麼敢说这样的话?

They ~d not look me in the face.

他们不敢直视我的脸

If he ~ say such a thing again, I shall knock him down.

如果他胆敢再说这种话,我一定把他打倒在地

2. 作实义动词，可参考want的用法，后跟不定式作宾语dare to do sth. 否定和疑问需要借助于助动词完成：

1 敢…,胆敢

He does not ~ to tell us.

他不敢告诉我们

Do you ~ to ask her?.

你敢问她吗?

I have never ~d (to) speak to him.

我从不敢和他说话

I wonder how she ~s (to) say that.

我奇怪她怎麼敢那样说

Don't you ~ (to) touch me.

你敢碰我?

但注意到上面三个省略to的情况，这个和need不一样（need也是一个兼类动词）

The little girl__________to the forest .

A didn't dare go ? B dared not to go ?C dared not go D dares to go.

析：据上面的词典的例句，B是错的，因为从not放dared后可知道，说话者将dare作情态动词看待了，而情态动词后面是跟无to不定式的。

C是正确的，而且是“参考答案”。如上所说，这里的dare作情态动词用，后直接跟not构成否定。再跟动词原形。

译：这小女孩（过去）不敢去那片森林。

但出题者没有想到的是，A和D也是正确的句子。

A。显然是将dare作实义动词看特了，因为它用了助动词didn't, 所以照理后跟有to不定式作其宾语，但我们在词典中发现，这种情况下，这个to可以省略！！！命题者没有查过词典，不知道，所以认为A不对。考生要知道考官的心理及知识水平，建议考试时，不要选择A

而答案D，显然是当它作实义动词用了，只不过是一般现在时，表示这女孩胆子大，改进那片森林，第三人称作主语，谓语动词dare也加了s,后面也跟了to do sth. 没有上文规定说这个一定得用否定句，所以D也是对的：

译：D。这个小女孩敢去那片森林。

评：这是一失误题，不会出现在中考，更不会出现在高考中。“正确”答案是C
