情态动词need用法小结
一、NEED与句子类型
(本条可参照ANY的用法。) NEED可用于：
1.否定句/含有否定意义的句子 1)否定句
含not/hardly/never/nobody等词语。 I needn’t say anything. He need hardly advise me. You never need tell me this or that. Nobody need help me. I don’t think he need come.(否定转移)
注：NEEDN’T的意思其实有三种，即不必要/不一定/不应该，视具体语境而定。 2)含有否定意义的句子
含only/but/all/before/than等词语。 He need only wait here. You need but consider the matter to understand its importance. That’s all that need be said.
Do not stay longer than you need. There was another hour before I need go out into the cold. 2.疑问句/表示疑问的从句 1)疑问句(包括否定疑问句) Need he say it again? 2)表示疑问的从句
I wonder whether/if I need see her. 3.条件句
含if/unless等词。
If he need come, he will. 本条要点简单概括起来就是，NEED不能用于肯定句。以下的各种用法也遵循这条规则。
二、NEED与时态 1.现在时
NEED常用于现在时。 You needn’t stay. 2.将来时
You needn’t have your blood pressure taken tomorrow. 3.过去时
NEED的过去式仍然是NEED。 1)过去时间由一过去时间状语表示 He need not come yesterday. 2)过去时间由另一过去时动词表示。 All he need do was to inquire. It was clear that he need never trouble to get up at seven again. I told him he needn’t be in a terrible fix. 注：表示过去的NEED常用于间接引语中。 (本条可参照must的用法)
三、NEED与虚拟语气 1)NEED用于虚拟条件句
(本条可参照虚拟条件句的构成及用法。) If money were useless, we need not struggle for it. If you had been careful enough, you need not have suffered. 注：本条用法较为少见。
2)NEED单独使用：NEEDN’T HAVE DONE (本条可参照SHOULDN’T HAVE DONE的用法。) You need not have worried. 注：NEED HAVE DONE的形式较为少见
Need you have scolded him so severely for his bad work? He had done his best.(否定意味)
He need have gone and sent that letter in person.(实际上没有做)
四、NEED与推测
NEEDN’T表示“不一定”。 (本条可参照must/can的用法。) 1) NEEDN’T+BE
It needn’t be hot in Florida now. 对比：
It can’t be hot in Florida now.(一定不) It must be hot in Florida now.(一定) 2) NEEDN’T+HAVE DONE
He need not have seen much of the world, though he is an old man. 对比：
He can’t have seen much of the world, for he is just a little boy. He must have seen much of the world, for he has been traveling so widely.
五、NEED与问句 1)反意疑问句的构成 You needn’t go, need you? 2)答句的构成 --- Need he go? --- Yes, he must/has to/needs to. --- No, he needn’t.
(本条可参照must的用法)
六、情态动词NEED与实义动词NEED 1)使用范围
作为实义动词的NEED有人称、数和时态的变化，使用范围更为广泛，不受句子类型和时态的限制。在肯定句、过去时和将来时的句子中，一般使用作为实义动词的NEED。
He needs to see a doctor straightaway.(此处needs to不能换做need，因为本句是肯定句)
Will he need to start earlier? 注：
NEED TO BE DONE与NEED DOING可以互换，后者更为常用(这里的NEED均为实义动词)。 2)含义差别
NEEDN’T HAVE DONE与DIDN’T NEED TO DO表示“不必要”的时候，在意义上有所差别，前者表示“本不必做„„”，实际上已经做了(NEED为情态动词);后者单纯地表示“不必做„„”(NEED为实义动词)。
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‟m afraid I must be going now. 12. You must be hungry. Have something to eat. 13. They must be twins. 14. There‟s a lot noise from next door. They must be having party a party. 15. 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
⑴ shall 作为情态动词，用于二，三人称，表示说话人的意愿，有........“命令”，“警告”，“威胁”，“强制”，“允诺”等意思。(一人称用 shall是将来时)
① You shall do as I say.(命令) ② Tell him that he shall have the book tomorrow.(允诺) ③ You shall have whatever you want.(诺言) (我答应)你要什么我给你什么。
④ He shall be sorry for it one day.(警告)
8 有一天他会后悔的，我告诉你。
⑵ 在疑问句中，shall 用来征询对方意见或请求指示，用于一，三...........人称。译成“(你说)…好吗?”
① Where shall I wait for you? (你说)…
② 区别： Shall he come at once? (你说)他要不要立刻来?
(征求你的意见，情态动词)
Will he come at once?他将立刻来吗?(纯将来时) ③ Shall we start the meeting now?
④ Let‟s have a rest, shall we?(Let‟s 包括对方) 对比：Let us have a rest, will you?(Let us 不包括对方) 对于上述这类问句的回答，没有严格不变的肯定或否定模式。 ⑤ Shall I open the window? Yes, please. ⑥ Shall I get you some more tea? Yes, please. ⑦ Shall we have a meeting tomorrow? Yes ,I agree./ ( Well, I don‟t think we need to.) ⑧ Shall we go there by bike? All right.

一、如何变一般疑问句： 1. 有be动词(am，is，are)，情态动词can, may, would的，直接将这些词提前，句尾加?。 2. 实意动词作谓语的，在句首加Do或Does，谓语动词用原形。 3. 在一般疑问句中，some变any(委婉请求的句子不变)，and可变为or。 4. 一般疑问句用Yes或No回答。
二、如何变否定句：
1. 有be动词(am，is，are)，情态动词can, may, would的，直接在这些词提后加not，可缩写。
2. 实意动词作谓语的，在谓语动词前加don’t或doesn’t，谓语动词用原形。 3. 在否定句中，some变any，and变为or。
三、固定搭配
1. 使用动词原形(do)的几种情况：
① 助动词(do，does)及情态动词(can，may，would)后跟动词原形;
② 祈使句的句首用动词原形;
③ help sb. do sth.(帮助某人做某事)let sb. do sth. (让我们做某事)。 2. 使用动词不定式(to do)的几种情况：
① to do作目的状语，如：Come to visit
② to do作定语，如：a funny time to eat breakfast; a good place to visit, sth. to eat/drink;
③ want to do =would like to do(想做某事);want sb to do =would like sb to do(想让某人做某事);hope to do=wish to do(希望做某事);help sb. to do sth.(帮助某人做某事)
