1、精選優(yōu)質(zhì)文檔-傾情為你奉上初中英語情態(tài)動詞專項練習(xí)題初中英語情態(tài)動詞用法歸納情態(tài)動詞有具體的詞義，但也同助動詞一樣，需要與其他詞語一起構(gòu)成句子的謂語，另外情態(tài)動詞沒有人稱和數(shù)的變化，情態(tài)動詞后必須跟動詞原形?？键c一：can，could, may，must 等情態(tài)動詞的用法：1. can 的用法：（1）.表示能力、許可、可能性。 表示能力時一般譯為“能、會”， 即有種能力，尤其是生來具備的能力，此時may 和must 均不可代替它。如：She can swim fast, but I cant . 她能游得很快，但我不能。I can see with my eyes. 我用眼睛看。（2）.表示許

2、可，常在口語中。如：You can use my dictionary. 你可以用我的字典。（3）.表示推測，意為“可能”， 常用于否定句和疑問句中， 此時cant 譯為“ 不可能”。 如：Can the news be true? 這個消息會是真的嗎？Can it be our teacher?那個人有可能是我們老師嗎？No, it cant be our teacher. He is on a visit to the Great Wall.不可能。咱們老師正在游覽長城呢。【例題】I think Miss Gao must be in the library. She said she w

3、ould go there. No. She _be there, I have just been there. A.cant B.mustnt C.neednt D.wouldnt【解析】根據(jù)下文“我剛?cè)ミ^那兒”可知，應(yīng)為“ 不可能”， cant 表示推測答案 A2. could的用法：（1）.can的過去式，意為“ 能、 會”，表示過去的能力。如：He could write poems when he was 10. 他十歲時就會寫詩。（2）. could在疑問句中，表示委婉的語氣，此時 could 沒有過去式的意思。如:Could you do me a favour? 你能幫我個忙

4、嗎？Could I use your pen? 我能用一下你的鋼筆嗎? Yes, you can.可以。（注意回答）3. may的用法：（1）.表示請求、許可，比can 正式，如：May I borrow your bike? 我可以借你的自行車嗎？You may go home now. 現(xiàn)在你可以回家了?！纠}】_ I borrow your MP3? Sure . Here you are. A. May B.Should C.Must D. Would【解析】 在此處表示請求，意為“ 做可以嗎”。答案：A (2) .表示推測，談?wù)摽赡苄?，意為?可能， 或許”，一般用于肯定句中。 如：

5、It may rain tomorrow . 明天可能會下雨。She may be at home. 她可能在家呢. (3) .may的過去式為might ，表示推測時?？赡苄缘陀趍ay。 如：He is away from school. He might be sick.他離開學(xué)校了，可能是他生病了。 (4) . 表示希望、祈求、祝愿，?？勺g為“祝愿”。通常是用may +主+V 例如：May you have a good time. 祝你過得愉快。 May you be happy! 祝你幸福！ May you succeed！祝你成功！4. must的用法：(1).must 表示主觀看

6、法，意為“必須、一定”。 如：You must stay here until I come back.在我回來之前你必須呆在這兒。Must I hand in my homework right now? 我必須現(xiàn)在交作業(yè)嗎？(2) 其否定形式mustnt表示“ 一定不要 ” “千萬別” “禁止, 不許”. 如：You mustnt play with fire. 你不許玩火。You mustnt be late. 你一定不要遲到。（3）對must引導(dǎo)的疑問句，肯定回答為must，否定回答為neednt 或 dont have to .如：Must I finish my homework?

7、我現(xiàn)在必須完成作業(yè)嗎？No, you neednt.不，你不必。 (4)must表示有把握的推測，用于肯定句。如: The light is on, so he must be at home now.燈亮著，他現(xiàn)在肯定在家。注意其反意問句的構(gòu)成形式：當(dāng)must表示肯定的判斷、推測時，其反意疑問句要用實際問句的助動詞來構(gòu)成。如：She must have seen the film before，hasnt she?(注意反意疑問句的后半部分)You must have met uncle Wang in the shop yesterday，didnt you? (注意反意疑問句的后半部分)

8、5. need的用法：（1）.need 表示需要、必須，主要用于否定句和疑問句中，其否定形式為neednt，意為“沒有必要，不必”。 用need 提問時，肯定回答為 must，否定回答為 neednt或dont have to。 如：Need I stay here any longer? 我還有必要留在這兒嗎？Yes, you must .是的。No. you neednt /dont have to. 不， 你不必。(2).need 還可以作實義動詞，此時有人稱、數(shù)和時態(tài)的變化，如果是人作主語后邊多接動詞不定式。如：I need to do it right now. 我需要馬上做這件事。

9、He needs to learn more about the girl.他需要多了解那個女孩。如果是物作主語，一般用need doing 與 need to be done這種情況下應(yīng)注意兩點：.主動形式的動名詞doing具有被動的含義；.該動名詞可以改為其動詞不定式的被動形式而句子的意義不變。例如：. The door needs painting. = The door needs to be painted. 那扇門需要油漆一下。Your car needs mending. = Your car needs to be repaired. 你的車需要維修了。6. dare 的用法：

10、dare意為“敢、敢于”, 用法近似于need，有兩種詞性：（1）dare 作為情態(tài)動詞，多用于否定句、疑問句或條件句中，無第三人稱單數(shù)形式，只有一般現(xiàn)在時和一般過去時。如：Dare he tell them what he knows? 他敢告訴他們所知道的情況嗎？I darent ask her will you do it for me? 我可不敢問她，你能幫我問問嗎？（2）dare 作為實義動詞，此時有人稱、數(shù)及時態(tài)的變化。如：He doesnt dare to break his promise.他不敢食言。注意：在口語中，dare 的各種形式常與不帶to 的不定式連用。如：Do y

11、ou dare tell her what I said?你敢告訴她我說的話嗎？I didnt dare look at him.我不敢看他。7. shall 的用法：shall表示征求對方意見（多用于第一、三人稱），如：Shall we go out for a walk? 我們出去散步好嗎？在英語中，我們可以用其他多種方式提出我們的建議或征求對方意見。(1).用“Lets do.”來提出建議。如：Lets go for a walk after supper.(2).用“What/How about.?”來提出建議；about后接名詞或動詞ing形式。如：What about/How ab

12、out a drink? What about/How about taking Tom with us?(3).用“Why not.?”來提出建議，表示“何不”not面后接動詞原形?！癢hy not.?”實際上是“Why dont you/we.?”的簡略形式。如：Why not meet at the school gate at eight? Why dont we stay here another day?(4).用“Would you like.?”來提出建議，意思是“你想要嗎?”Would you like后可接名詞或不定式。如：Would you like a cup of t

13、ea?Would you like to go and see her?因此，如果我們說：“去游泳好嗎?”英語中可有這樣幾種表達法：Shall we go for a swim?Lets go for a swim，shall we?What about/How about going swimming?Why not go for a swim?Would you like to go for a swim?What do you think of going for a swim?8. should的用法：（1）.should 意為“應(yīng)該” ，可表示勸告、建議、義務(wù)、責(zé)任等。 如：We s

14、hould protect the environment. 我們應(yīng)該保護環(huán)境。（2）Should have done 表示對過去動作的責(zé)備、批評。如：You should have finished your homework.你應(yīng)該已經(jīng)完成作業(yè)了。（事實上你沒有完成。）9. will 的用法：will表示意愿、意志、打算，可用于多種人稱。如：I will help you if Im free this afternoon.今天下午如果我有空，我就會幫你。注意：1、will在there be句型中的形式及其句式變換。 由于“一般將來時”的結(jié)構(gòu)可以用“will+動詞原形”來表示，所以ther

15、e be句型的一般將來時的形式就是there will be。（一定不能說there will have）例如： There are many students in our school. There will be many students in our school. There will be a sports meeting next week. 一定不能說：There will have a sports meeting next week.2、will 與be going to do sth區(qū)別：. be going to 表示近期、眼下就要發(fā)生的事情，will 表示的將來時間

16、則較遠一些，如：He is going to write a letter tonight. He will write a book one day. . be going to 表示根據(jù)主觀判斷將來肯定發(fā)生的事情，will表示客觀上將來勢必發(fā)生的事情。He is seriously ill. He is going to die. He will be twenty years old. . be going to 含有“計劃，準(zhǔn)備”的意思，而 will 則沒有這個意思，如： She is going to lend us her book. He will be here in half

17、 an hour. .在有條件從句的主句中，一般不用 be going to, 而多用will, 如： If any beasts comes at you, Ill stay with you and help you 10. had better 的用法：had better “最好”，沒有人稱和數(shù)的變化，后面接動詞原形，其否定形式為：had better not do。如：We had better go now. 我們最好現(xiàn)在就走。You had better not give the book to him.你最好不要把這本書給他?？键c二：含有情態(tài)動詞的疑問句的回1.對 may 引出

18、的問句，可以有下列回答方式：肯定回答：Yes, you may. Yes, of course.Yes, certainly.Sure .否定回答：No, you mustnt. No, you cant.2.對must引出的疑問句，回答方式為：Yes, must. No, neednt/ dont have to.3.could在疑問句中，表示委婉的語氣，此時 could 沒有過去式的意思。如:Could you do me a favour? 你能幫我個忙嗎？Could I use your pen? 我能用一下你的鋼筆嗎? Yes, you can.可以。（注意回答）4. shall引出

19、的疑問句用于第一人稱， 表示征求對方意見或客氣的請求。其回答方式有以下幾種： Yes, please.All right.No, thank you.5.would you的回答方式有以下幾種：Yes, I will. (No, I wont.)Sure . (Im sorry , I cant.)All right/ OK/ With pleasure.Certainly. (No, thank you .)Yes, please.【例題】Would you do me a favour and pass on my thanks to Lily? _.A.Thats right B.Wit

20、h pleasure C.It doesnt matter D.No trouble【解析】A. “對了” ，B. “ 樂意效勞”, C. “ 沒關(guān)系” D. “不費事”。答案：B考點三: 不同情態(tài)動詞的否定意義也不同：1.（1）.cant可譯為“不會”， 如：I cant play basketball. 我不會打籃球。（2）當(dāng)句子表推測時，用cant 表達不可能， 如：He cant be ill. He is playing chess with Tom. 他不可能病了，他正和Tom 下棋呢。（3）cant 還可用來回答“ May I ? ” 這樣的問句。 如：May I come in

21、 ? 我可以進來嗎？No, you mustnt. / cant. 不，你不能。（4）cant 還可用于固定習(xí)語中。cant help doing 禁不住，情不自禁 cant wait to do sth 迫不及待 如：She cant help crying. 她不禁大哭起來。The children cant wait to open the box. 孩子們迫不及待地想打開盒子。2. may的否定式為 may not，譯成“ 可能不”，如：He may not be at home. 他也許不在家。3.（1）mustnt 表示不許，不可。 如：He mustnt leave his ro

22、om. 他不許離開他的房間。You mustnt talk in class. 你們不可以在課上說話。(2) mustnt 也可用于以 may 表示要求時的否定回答中。 如：May I stand here? 我可以站在這里嗎？No, you mustnt (cant). 不，不行。4.（1）neednt 意為“ 不必”。如：You neednt meet him unless youd like to.你不需要見他，除非你愿意。（2）neednt + have+ 動詞的過去分詞，表不需要完成但已完成的動作，暗含時間或精力上的浪費。 如：You neednt have bought it. 你

23、沒必要買它（但你卻買了）。5. shouldnt 表示不應(yīng)該。 如：You shouldnt feel so unhappy over such little things. 對于這種小事，你不應(yīng)該感到這么不高興?？键c四: 情態(tài)動詞的被動語態(tài)含有情態(tài)動詞的被動語態(tài)的結(jié)構(gòu)為： 情態(tài)動詞+ be + done (動詞的過去分詞)。做題時要兼顧情態(tài)動詞和被動語態(tài)這兩個方面。如：You neednt get up so early every day.你不必每天都起這么早。She shouldnt speak to her mother in that way.她不應(yīng)該用那種方式和媽媽說話。More

24、and more trees must be planted in China.在中國必須種植更多的樹木。Many of the stars can not be seen because they are far away from us.很多星星我們都看不到，因為它們離 我們太遠了?？键c五: 情態(tài)動詞表示推測的用法:一、“情態(tài)動詞+動詞原形”表示對現(xiàn)在的推測。1、can表示推測時一般用于否定句或疑問句。 如：That man cant be her husbandshe is still single.Who is knocking at the door?Can it be the po

25、stman?2、must表示肯定的推測，一般用于肯定句中。 如：He must be in his office now.Mr Li must be working now， for the lights in his office are still on.3、might 表示推測時不一定是may的過去時，只是表示其可能性較小。如：The man may be the headmaster.Where is Mr Li? He might be working in his office. May Mr Li come? He might not come here.4、Could表示推測時

26、，語氣can比要弱，說話者留有余地。如：Could it be an animal?It could not be， because it is not moving.5、Should表示推測的可能性比較大，僅比must的可能性 小一點。如：It is already 10 oclock now they should be there.二、情態(tài)動詞表示對過去可能發(fā)生的動作或存在過的動作的推測性用法。1、“must +have done/been-”表示“過去一定發(fā)生過某事或存在過某種狀態(tài)”，不用于“musnt+have-”形式。如：She must have seen the film be

27、fore，hasnt she?(注意反意疑問句的后半部分)You must have met uncle Wang in the shop yesterday，didnt you? (注意反意疑問句的后半部分)2、“should +have done /been-”表示“本應(yīng)當(dāng)做某事，而實際上并沒有做”；“ shouldnt+完成式”表示“本來不應(yīng)當(dāng)做，而實際上卻做了”。以上結(jié)構(gòu)常帶有說話者的責(zé)備的感情色彩。如：You should have finished your homework earlier (but in fact you did not finish it on time).Y

28、ou shouldnt have gone to bed when you woke up at five (but in fact you went to bed again then).3、“neednt+完成式”表示“本來沒有必要做某事，而實際上卻做了”。如：There was plenty of time.

29、he man couldnt have stolen her car.5、“could+have done/been-”表示“過去本來能夠，可以做某事或成為某種狀態(tài)，而實際上沒有”，說話者有些遺憾?！癱ould sb. have done /been-？”是它的問句形式。如：You could have stayed with the Smiths while you were in New York (but in fact you stayed in a nearby hotel .) Could Mr Li have helped this girl student?6、“may/mig

30、ht+完成式”表示“過去可能，本來可以于某事而實際上沒有干”，might的可能性較小，語氣較弱。 如：He may have finished reading the book. She might have given you some help，however bus she was.【情態(tài)動詞易混點歸納】易混點一: can和be able to:兩者表示能力時用法相同，但can只有原形“can”和過去式“could”兩種形式，在其他時態(tài)中 要用be able to 來表示。另外 be able to 常常指經(jīng)過努力，花費了時間和勞力之后才能做到某事。如：Jim cant speak En

33、 be為動詞原形 句中，作謂語maybe 副詞，大概、也許，相當(dāng)于perhaps 句首，作狀語例如：He may be wrong , but Im not sure. 也許他錯了，但我也不確定。易混點四：cant 和 mustnt1. cant 根據(jù)其基本用法可譯為：（1）不會。如：I cant speak English . 我不會說英語。（2）不能。如：We cant do it now because its too dark.天太黑了，我們現(xiàn)在干不了。（3）否定句中表示推測。“不可能”，如：The man cant be our teacher because he is much
