第五篇：情态动词小结

情态动词有：can(could)， may(might)， must，have to, shall(should)，will(would)，need, dare, ought to等。 一. 情态动词can, may, must用法 ㈠基本用法 1. can ⑴ 会，能够 --Can you swim? --Yes, I can. --No, I can‟t. ⑵ 口语中代替may. You can (may) park here. 你可以把车停在这里。(许可) 2. may允许，许可 --May I come in? --Yes, you may./Sure, come on in. --No, you mustn‟t./No, you can‟t.

No, you‟d better not. 3. must必须 --Must we finish the exercise today? --Yes, you must. --No, you needn‟t./No, you don‟t have to. 4. need 需要，必需--Need you go now?= -- Must you go now? --Yes, I must. --Yes, I must. --No, I needn‟t. --No, I needn‟t. (need作为情态动词，通常用在否定句和疑问句中。)

1 注意一：can 与be able to 都可以表示“能力”，区别是： ⑴ can只有现在和过去两种形式

I can play the piano. She couldn‟t play the piano when she was a little girl. ⑵ be able to ① 有更多的形式和时态

We shall/will be able to finish the work next week. I haven‟t been able to find the book. ② 指具体一次活动

I can swim but I am not able to cross the rough sea. 有时两者可以互换: I‟m not able to (can‟t) answer your question. Are you able to (Can you) type(打字)?

注意二：could的用法

⑴ 作为can的过去式，表示过去的能力。

When I was young I could climb any tree in the forest. 这时也可用was(were)able to ⑵ 用来代替can，婉转地提出请求，想法，建议等。回答这种情况下could引导的一般疑问句时，不用could，而要用can。 A: Could you tell me how to get to the hospital? B: Of cause, I can. 注意三：must的否定形式表示“不得”，“一定不要”，“禁止”

2 ① You mustn‟t take photos in here. It‟s forbidden(禁止). ② You mustn‟t drive without a license(驾照). ③ We mustn‟t be late, must we?

(与第4页对比，此must不表猜测,两回事。) 注意四：must的过去式是must，常用 had to 代替。 I had to see the dentist. 注意五：must 和 have to 都可以表示必须，但must表示说话人的主观看法，have to表示客观需要。 You must say sorry to me for that. You have to drive quickly, we have little time. 注意六：May+动词原形表“祝愿”。

May you succeed. May you be happy every day. ㈡ 可能性用法

1. can表示“可能性”① 疑问句：只能用can

Who can it be ?

② 否定句：cannot(can‟t)“不可能 It cannot be Jenny. 2. may表示“可能性”① 否定句：may not“可能不”

It may not be Jenny.

② 肯定句：“大概”，“也许”，“可能” It may be Jenny.

3 3. must表示“可能性”，只能用于肯定句，表推测：“一定是”，“准是”，“必是”，“必定”。

It must be Jenny. 小结表示“可能性”：

疑问句：只能用can 否定句：cannot(can‟t)“不可能”(反义词是must“准是”) may not“可能不”

肯定句：may “大概”

must“准是”(反义词是can‟t) 注意一: 在表示“可能性”时，凡是对过去事物的猜测，不管是疑问..句，否定句还是肯定句，都要用完成时。 ...① It must have rained last night. You see, the ground is still wet. ② He can‟t have been to your home. He doesn‟t know your address注意二：may+原型 表示 现在或将来的可能性。若表示对过去事物 .... 的猜测，则用完成时。 ③ He may come today.(tomorrow) He might come today.(tomorrow) (might语气更不肯定，不是may的过去时) ④ She might have called for help.她可能大声喊“救命”了。 请翻译下里句子：

1. Where can Wei Fang be?

4 2.That can‟t be Mary. She is in hospital. 3. Surely you can‟t be hungry. You‟ve only just had lunch. 4. The key can‟t be in the room. I have just searched it carefully. 5.

5 B: That must have been nice. 注意三：must表示猜测时的反义疑问句

⑴ “must be +表语”的结构，must表示肯定猜测时，含有“准是”，“势必”，“一定”等意义时，反义疑问句用“isn‟t/aren‟t+主语” They must be hungry after the long walk, aren‟t they? ⑵ “must have done” 表示猜测时，反义疑问句用“haven‟t/hasn‟t +主语”或“didn‟t+主语”

① They must have studied English before, haven‟t they? ② She must have met a fairy(仙女), hasn‟t she? ③ You must have seen the film last week, didn‟t you? ........解题秘笈：① 把must去掉 ② 找时间状语 ③ 重新组成一新句子 ④ 按新句子的时态造反义疑问句

① You must have been to Beijing, ___ __?

去掉must;无时状;重组成You have been to Beijing; 故答案为：haven‟t you ② You must have finished your homework yesterday, .........___ __?去掉must;时状为yesterday; 重组成 You finished your homework yesterday; 故答案为：didn‟t you 二.情态动词need的用法
