第一篇：情态动词用法教案
情态动词教案
情态动词
1. 概念: 情态动词: 表示说话者的某些观点或态度的词语.如 “能” , “或许” , “必须” , “需要” , “应该” 等. 2. 情态动词主要有: can, may, must, need, should, … 这些情态动词后面 + 动词原形. 3. 用法
① can ⑴ 表示能力,意为”能, 会”. 如:
eg: I can play basketball. 我会打篮球.
---Can you play basketball ? 你会打篮球吗? --- Yes, I can. / No, I can’t. 是的, 我会. / 不, 我不会.
⑵ 表示怀疑、猜测，常用 be 连用, 放在否定句和疑问句中。如：
eg: He can’t be in the room. 他一定不在房间里.
⑶ 表示请求或允许, 多用于口语中, 意为”可以”, 相当于 may. 如:
eg: You can go now. 你现在可以走了.
② could ⑴ 是can 的过去式, 表示过去的能力. 如:
eg: I could swim when I was a child. 当我还是一个小孩子的时候我就会游泳了.
⑵ couldn’t: “不能” 用could 提问肯定和否定回答分别用 could, 和 couldn’t.
如:
eg: --- Could you skate last year? 你去年会滑冰吗?
--- Yes, I could. / No, I couldn’t. 是的, 我会. / 不, 我不会.
③ may ⑴ 表示推测, 意为“可能; 或许” 用于肯定句中.
eg: He may be a teacher. 他或许是一个老师.
⑵ 表示请求、许可， 意为”可以” 如: eg: ---May I borrow your book? 我可以借你的书吗?
--- Yes, you can. / No, you mustn’t. 是的, 可以. / 不, 你你禁止借书. 注意: 当由may 来提问的时候, 肯定回答我们用Yes, you can. 否定回答用 No, you mustn’t. ④ must ⑴ 表示“必须、应该“;
eg: You must do your homework. 你必须做作业.
⑵ 表示推测, “一定” 常与be 动词连用. eg: He must be in the classroom. 他一定在教室.

eg: You mustn’t smoke. 禁止吸烟.
⑷ must 放于句首提问, 肯定回答Yes, you must. 否定回答 No, you needn’t.
⑸ must 与 have to 的区别：
must强调主观的看法.
have to 强调的是客观因素. eg: I must do my homework. 我必须做作业.(个人看法)
I have to go home now, because my mother is ill. 我不得不回家，因为我妈妈病了.(客观原因所导致)
⑤ need ⑴ 作情态动词使用后跟动词原形. You needn’t come here so early.
⑵ 作实义动词使用后接to do, He needs to drink some water. 他需要喝些水. 变否定句: He doesn’t need to drink any water.
变疑问句: Does he need to drink any water? Yes, he does. / No, he doesn’t.
⑥ should “应该” 一般指应尽的某种义务.
eg: As a student, we should finish our homework. 作为一个学生，我们应该完成作业.

2. He must be watching TV , isn’t he ?
3 Tom must have lived her for a long time, hasn’t he ?
4. She must have arrived yesterday, didn’t she?
注：如选择题中(以She must have arrived yesterday, didn’t she?为例)既有didn’t she又有hasn’t she则以didn’t she?为最佳答案
第三篇：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. You may/ can go and ask him. But he may not answer you. 6.A：Look! Someone is coming. Who can it be? B: It may be our headmaster. A: It can‟t be him. He has gone to Shanghai. B: It must be Mr. Zhang. He looks like our headmaster. 7. Anna may know Tom‟s address. 8. They may be waiting at the station. 9. I may be going to Europe next year. 10.He may have gone abroad. 11.

I can‟t find him anywhere. He must have left. 16. I can‟t find my book. I must have left it at home. 17. You must have been thinking of something. 18. A: We went to Hainan for the winter vacation.
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
⑴ need 表示“需要”，“必需”。作为情态动词，通常用在否定句和疑问句中。
① He needn‟t pay for it.( 情态动词)
6 =He doesn‟t need to pay for it.(行为动词) ② --Need you go now?= -- Must you go now? --Yes, I must. --Yes, I must. --No, I needn‟t. --No, I needn‟t. ⑵ need也可用作行为动词，其变化与一般动词相同。 ① We need to think it over.(肯定句) ② Does he need to know it?=Need he know it? ③ She didn‟t need to go.=She needn‟t go. ⑶ 按句型背：
need doing=need to be done ① The door needs painting. =The door needs to be painted. ② The old man needed looking after. = The old man needed to be looked after. 三.情态动词dare的用法
⑴ dare 表示“敢” 作为情态动词，通常用于否定句，疑问句或条件句中。dare 作为情态动词只有两种形式:dare, dared(当主语是第三人称单数时，dare 不加s) ① She dare not do so.(否定句) ② Dare he do it? (一般疑问句) ③ How dare you say I‟m unfair. (特殊疑问句) ④ Jump if you dare.有胆量你就跳。(条件句)
7 ⑵ 除了在“I dare say…” 这种习惯用语中，dare 在肯定句中作 情态动词的情况是很少的。(特殊用法，口语中常用，按句型背) ① I dare say you are wrong. ② A: If you die, who will get your money?
B: I dare say my uncle will. I have no other relatives. (亲戚) ⑶ dare 也可用作行为动词，其变化与一般动词相同。 ① Who dare to go? ② I don‟t dare (to) ask her. 问：此句中的to 为什么可以省略?
答: 当dare 作为①行为动词②在否定句中(两个条件必须同时具备)，其后面的不定式可以省略to。又如： ③ We didn‟t dare (to)try a shot. 四.情态动词shall和should的用法
