㈠．概述

情态动词：动词本身具有情态意义，表达说话人的态度、情绪和语气。情态动词不能单独作谓语，必须和其他动词一起构成谓语。情态动词主要有：can,could;may,might;must;ought to;need; dare;shall;will,should;would. ㈡.用法：

★1.表能力can / be able to

Eg.①

He_______ run the 100m sprint in 11 seconds. ②

__________ this little girl read before she goes to the primary school?

归纳：can表示可能性时，指的是理论上的可能，它通常不用来表示某事实际发生的可能性或真实性。如：

Accidents can happen. Anybody can make mistakes．

注意：在过去时态的肯定句中需要某种条件或努力做成某事，我们要用was／were able to而不能用could。如：

①It was a holiday and the children ___________ go to the seaside．

②The girl worked hard so she ____________pass the final test．

③I’m sorry I haven’t_______________ play tennis with you recently. ★2.表义务(obligation) ⑴ought to/should

ought to与should意思接近，大多数情况下二者可以互换，但是should谈的是自己的主观看法, 用于各种人称。

ought to则更多反映客观情况，在谈到法律、义务和规定时使用。如：

理解例句&翻译

①We should／ought to help each other and learn from each other in our work．

②You shouldn’t spend so much time playing.

③She is your mother, so you ought to support her．

④Ought he to go? Yes, I think he ought (to).

⑵have to / must must与have to都可以表示“必须”的意思，但要注意以下两点区别。

注意：1）

must只有现在时，而have to有现在时、过去时和将来时。如：

①We must work hard, or we’ll fail in the examination．

②Two years ago, the poor girl_________leave school for lack of money．

2）must表示主观看法，have to则侧重于客观需要。如：

①We _______ be strict with ourselves in everything．

②In cities with many cars, some people _________ wear masks．

★3.表可能性（certainty）

might / may/ could / should / ought to / will / must

（可能性逐渐增大）

very uncertainty

almost certainty ①She might win a medal at the Olympics. ②She may be at home now. ③She could read and write at the age of 4. ④She should come to join us. ⑤She ought to / will / must help me whenever I am in trouble. ★4.表允许（permission）

can / could / may / might （从非正式场合到正式过渡）

informal / spoken

formal / written could比can 更委婉，might比may 更委婉

①—Can I watch the Olympics ?

—Yes, you can. /No, you can’t.

②—May I watch TV after finishing my homework? —Yes, you may. / No, you mustn’t. / No, you may not. / No, you’d better not.

★5.提出请求（make requests）

will / can / could / would（从非正式场合到正式过渡）

2

Informal

formal

①—Will / Can/ Could/Would you help me with my training? —Yes, I will/can/can/will. ★6.给出建议（make suggestions）

shall常用于第一，三人称，表示征求对方意见。

①—

Shall we / I / he / she / they do some exercise this morning?

— Yes. ②— Shall he come in?

— Ok. ★7.提供帮助（make offers）

①I’ll wash your sports jacket.

②Shall I get a ticket for you? ③Shall we carry the books for you ?

④Shall I clean the blackboard for you? give advice ★8.提出忠告（give advice）

①You should not/ought not to eat a lot before swimming. ②The students should spend all their time working at their lessons. 注意①：用于情态动词后的其他动词必须是不带to的不定式形式。如：

She could win the gold medal 注意②：情态动词后的动词如果是进行式，表示正在进行中的动作；情态动词后的动词如果是完成式，则表示过去可能做过的动作。

①The boys may be playing football on the playground. ②The boys may have finished their homework by the time school is over. ③He plays basketball very well. He must have practiced it a lot. ④Our headmaster must have been to USA, for he knows the country so much 注意③：mustn’t / needn’t

•

mustn’t 解释为“不准，不许”，语气强烈；needn’t “不需要，没必要”，语气缓和。

•

You mustn’t miss this football match. It’s very important.

•

You needn’t watch the game if you don’t want to.

•

—Must we clean the classroom?

•

—Yes, you must. /No, you needn’t.

注意④：must have done 的反意疑问句

①You must have seen the film, haven’t you?

②You must have seen the film last week, didn’t you?

③His parents must have beaten him, haven’t they? ④His parents must have beaten him yesterday, didn’t they?

归纳：对已发生的过去情况的推测，若陈述句谓语部分有“must have done”，而且有表示过去的时间状语，问句部分用_______；若没有表示过去的时间状语，问句部分用_______或__________ 注意⑤：need / dare作为情态动词时，两个词常用于疑问句和否定句。

①—Need I help you?

—Yes, please. ②You needn’t telephone him now.

③How dare you talk to the teacher like that? ④The girl dare not go out alone at night. 四、巩固练习
