第四篇：情態動詞小結
情態動詞有：can(could)， may(might)， must，have to, shall(should)，will(would)，need, dare, ought to等。 一. 情態動詞can, may, must用法 ㈠基本用法 1. can ⑴ 會，能夠 --Can you swim? --Yes, I can. --No, I can?t. ⑵ 口語中代替may. You can (may) park here. 你可以把車停在這里。(許可) 2. may允許，許可 --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必須 --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作為情態動詞，通常用在否定句和疑問句中。)
1 注意一：can 與be able to 都可以表示“能力”，區別是： ⑴ can只有現在和過去兩種形式
I can play the piano. She couldn?t play the piano when she was a little girl. ⑵ be able to ① 有更多的形式和時態
We shall/will be able to finish the work next week. I haven?t been able to find the book. ② 指具體一次活動
I can swim but I am not able to cross the rough sea. 有時兩者可以互換: 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 作為can的過去式，表示過去的能力。
When I was young I could climb any tree in the forest. 這時也可用was(were)able to ⑵ 用來代替can，婉轉地提出請求，想法，建議等?；卮疬@種情況下could引導的一般疑問句時，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(駕照). ③ We mustn?t be late, must we?
(與第4頁對比，此must不表猜測,兩回事。) 注意四：must的過去式是must，常用 had to 代替。 I had to see the dentist. 注意五：must 和 have to 都可以表示必須，但must表示說話人的主觀看法，have to表示客觀需要。 You must say sorry to me for that. You have to drive quickly, we have little time. 注意六：May+動詞原形表“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 疑問句：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”，“也許”，“可能” It may be Jenny.
3 3. must表示“可能性”，只能用于肯定句，表推測：“一定是”，“準是”，“必是”，“必定”。
It must be Jenny. 小結表示“可能性”：
疑問句：只能用can 否定句：cannot(can?t)“不可能”(反義詞是must“準是”) may not“可能不”
肯定句：may “大概”
must“準是”(反義詞是can?t) 注意一: 在表示“可能性”時，凡是對過去事物的猜測，不管是疑問..句，否定句還是肯定句，都要用完成時。 ...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 現在或將來的可能性。若表示對過去事物 .... 的猜測，則用完成時。 ③ He may come today.(tomorrow) He might come today.(tomorrow) (might語氣更不肯定，不是may的過去時) ④ She might have called for help.她可能大聲喊“救命”了。 請翻譯下里句子：
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表示猜測時的反義疑問句
⑴ “must be +表語”的結構，must表示肯定猜測時，含有“準是”，“勢必”，“一定”等意義時，反義疑問句用“isn?t/aren?t+主語” They must be hungry after the long walk, aren?t they? ⑵ “must have done” 表示猜測時，反義疑問句用“haven?t/hasn?t +主語”或“didn?t+主語”
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? ........解題秘笈：① 把must去掉 ② 找時間狀語 ③ 重新組成一新句子 ④ 按新句子的時態造反義疑問句
① You must have been to Beijing, ___ __?
去掉must;無時狀;重組成You have been to Beijing; 故答案為：haven?t you ② You must have finished your homework yesterday, .........___ __?去掉must;時狀為yesterday; 重組成 You finished your homework yesterday; 故答案為：didn?t you 二.情態動詞need的用法
⑴ need 表示“需要”，“必需”。作為情態動詞，通常用在否定句和疑問句中。
① He needn?t pay for it.( 情態動詞)
6 =He doesn?t need to pay for it.(行為動詞) 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也可用作行為動詞，其變化與一般動詞相同。 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.情態動詞dare的用法
⑴ dare 表示“敢” 作為情態動詞，通常用于否定句，疑問句或條件句中。dare 作為情態動詞只有兩種形式:dare, dared(當主語是第三人稱單數時，dare 不加s) ① She dare not do so.(否定句) ② Dare he do it? (一般疑問句) ③ How dare you say I?m unfair. (特殊疑問句) ④ Jump if you dare.有膽量你就跳。(條件句)
7 ⑵ 除了在“I dare say…” 這種習慣用語中，dare 在肯定句中作 情態動詞的情況是很少的。(特殊用法，口語中常用，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. (親戚) ⑶ dare 也可用作行為動詞，其變化與一般動詞相同。 ① Who dare to go? ② I don?t dare (to) ask her. 問：此句中的to 為什么可以省略?
答: 當dare 作為①行為動詞②在否定句中(兩個條件必須同時具備)，其后面的不定式可以省略to。又如： ③ We didn?t dare (to)try a shot. 四.情態動詞shall和should的用法
⑴ shall 作為情態動詞，用于二，三人稱，表示說話人的意愿，有........“命令”，“警告”，“威脅”，“強制”，“允諾”等意思。(一人稱用 shall是將來時)
① You shall do as I say.(命令) ② Tell him that he shall have the book tomorrow.(允諾) ③ You shall have whatever you want.(諾言) (我答應)你要什么我給你什么。
④ He shall be sorry for it one day.(警告)
8 有一天他會后悔的，我告訴你。
⑵ 在疑問句中，shall 用來征詢對方意見或請求指示，用于一，三...........人稱。譯成“(你說)…好嗎?”
① Where shall I wait for you? (你說)…
② 區別： Shall he come at once? (你說)他要不要立刻來?
(征求你的意見，情態動詞)
Will he come at once?他將立刻來嗎?(純將來時) ③ Shall we start the meeting now?
④ Let?s have a rest, shall we?(Let?s 包括對方) 對比：Let us have a rest, will you?(Let us 不包括對方) 對于上述這類問句的回答，沒有嚴格不變的肯定或否定模式。 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.

Will you go with me? ---Yes,I will.( I?m sorry, I can?t) ② Will you please open the window? =Please open the window, will you? ③ Don?t forget to give her some food and change her water, will you?(祈使句,用will you) ④ Be sure to write to us, will you?( 祈使句) ⑤ Let us have a look at your photos, will you? ⑥ –Alice, you feed the bird today,___? -But I fed it yesterday. A. do you B. will you C. didn?t you D. don?t you ⑶ 表示習慣性動作，有“總是”，“慣于”的意思。還表示“自然傾向”。
① He?ll talk for hours if you give him the chance. ② Fish will die out of water.
10 would ⑴ would是will的過去式，表示過去時間的“意志”，“愿望”用于各種人稱。
①“We will help you.” said they. They said that they would help us. ② No one would say that he couldn?t see the Emperor?s new clothes. ③ I promised that I would do my best.(按句型記) made a promise ⑵ 表示說話人的意愿或向對方提出請求，語氣比will婉轉。指的是現在時間。
