3、 I 的否定回答。、表示肯定和否定的猜測?！局攸c(diǎn)歸納 】情態(tài)動詞本身具有一定的詞義，表示某種感情和語氣。例如：You cant do it like that.(表示責(zé)備） 常見的情態(tài)動詞有 can , could , may , might , must , need , have to , should 等. 所有的情態(tài)動詞后面都接動詞原形. Eg: I can swim . He has to go now .1. can 能夠,會,可以 Eg:1. I can speak English well . 2.Can you tell me how to start the machine

4、?此外, can 用來表示否定推測和疑問推測 Eg:1. That cant be our English teacher because she has gone to Shanghai . 2.Can it be true ?情態(tài)動詞后加行為動詞原形構(gòu)成謂語。要掌握的情態(tài)動詞有：can (could), may(might), must, should.can 的用法1、表示“會，能夠”。例如： He can speak English.2、表示許可或請求，此時(shí)可等于may. 例如： You can use this pen. Can I borrow your book?3、表示懷疑、不

5、確定或猜想的情況,多用于疑問或否定句中。例如： Can it be true? He cant be at school, because I met him just now.He couldnt be a bad man.他不大可能是壞人。 1、can = be able to 但can只有兩種時(shí)態(tài)，而be able to 可用于多種時(shí)態(tài)。They will be able to tell you the news soon. 他很快就能告訴你消息了。注意：2、could不表示時(shí)態(tài)1）提出委婉的請求， （注意在回答中不可用could用can/cant）。 - Could I have th

6、e television on? - Yes, you can. / No, you cant.2）在否定，疑問句中表示推測或懷疑。 He couldnt be a bad man. 他不大可能是壞人。 may的用法。 1、表示許可或請求,其否定回答用cant或 mustnt。例如： May I go home now?Yes, you may. No, you cant.2、表示可能性或猜測。 例如： You may be right.3、當(dāng)表示請求時(shí), might比may 語氣更婉轉(zhuǎn)。當(dāng)表示猜測 時(shí)，might比may 更不確 定。1、表示必須，一定要或禁止。例如： You must do

7、 your homework right now. You mustnt smoke here.must 的用法。2、以must開頭的疑問句，其否定回答要用neednt.肯定回答用must例如：Must I clean the classroom now? Yes, you must. No, you neednt.3、must用于一般現(xiàn)在時(shí)和一般將來時(shí)，而其它形式用“have to” 來代替。如:She had to do some cooking yesterday because her parents were out.4、比較have to和must 兩詞都是必須的意思，have t

8、o 表示客觀的需要， must 表示說話人主觀上的看法，既主觀上的必要。My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厲害，我只得半夜里把醫(yī)生請來。(客觀上需要做這件事)He said that they must work hard. 他說他們必須努力工作。（主觀上要做這件事） 在否定結(jié)構(gòu)中： dont have to 表示“不必”mustnt表示“禁止”，You dont have to tell him about it.你不一定要把此事告訴他。You mustn

9、t tell him about it.你一定不要把這件事告訴他。 need的用法。need既可做實(shí)義動詞用，又可做情態(tài)動詞用。作為情態(tài)動詞，只能用于疑問句，否定句和條件句。 need 作實(shí)義動詞時(shí)后面的不定式必須帶to，1) 實(shí)義動詞： need（需要, 要求） need + n. / to do sth/doing sth2) 情態(tài)動詞： need，只用原形need后加do，否定形式為need not。Need you go yet? Yes, I must. / No, I neednt.3) need 的被動含義：need doing = need to be done 表示“應(yīng)該”，

10、有建議的意味,并不表示過去時(shí)態(tài)。例如: Everyone should work hard every day.We should protect our living environmentshould 的用法。4. need (需要) 既可做實(shí)義動詞也可做情態(tài)動詞實(shí)義動詞 need to do sth 需要做某事 Eg: I need to buy a big house . - Do you need to buy a big house ? - Yes , I do . No, I dont . He needs to borrow a map . - Does he need to

11、borrow a map ?2) 情態(tài)動詞 need do sth 需要做某事 Eg: I need buy a big house .5. have to 不得不 Eg: Its eleven oclock . I have to go now . He has to finish the work first . 請注意: I dont have to go now . He doesnt have to finish the work first. have to 和 must 的區(qū)別: have to 表示客觀因素 Eg: We are very glad at the party ,

12、 but its 11 , so we have to leave now . must 表示主觀因素 Eg: We must study hard to find a good job for ourselves .6. Youd better do sth 你最好做某事 Eg: Youd better buy the book . Youd better not do sth 你最好不要做某事 Youd better not run in the classroom .推測語氣對現(xiàn)在或?qū)砬闆r推測：I dont know where she is, she may be in Wuhan.

13、（2）must表對現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測時(shí)， must 后面通常接系動詞be 的原形或行為動詞的進(jìn)行式。 You have worked hard all day. You must be tired. 你辛苦干一整天，一定累了。（對現(xiàn)在情況的推測判斷）He must be working in his office. 他一定在辦公室工作呢。（3）否定和疑問分別用cant和can。 If Tom didnt leave here until five oclock, he cant be home yet.如果湯姆五點(diǎn)才離開這兒，他此時(shí)一定還未到家。Can he tell a li

14、e ? He cant tell a lie.*Must-should/may-might/could可能性依次減弱（4）ought to have done sth, should have done sth本應(yīng)該做某事，而事實(shí)上并沒有做。否定句表示“不該做某事而做了”。You ought to (should) have been more careful in this experiment.He ought not to have thrown the old clothes away.（事實(shí)上已扔了。）ought to 在語氣上比should 要強(qiáng)。He must be readin

15、g, isnt he?You must do it yourself, dont you?He must have gone over the article, hasnt he?It must have rained last night, didnt it?（3）表猜測語氣的反意疑問句的構(gòu)成固定搭配1、would rather do2、would rather not do3、would rather than 寧愿而不愿。4、Would like to do = want to 想要 5、had better表示“最好”had better 相當(dāng)于一個(gè)助動詞，它 只有一種形式，它后面要跟

16、動詞原 形。had better do sth had better not do sthIt is pretty cold. Youd better put on my coat.Shed better not play with the dog. 【實(shí)例解析】南海執(zhí)信中學(xué)初三英語備課組 例 1：-_the news be true?No, it_be true.A. Can, cant B. May, cantC. May, may not D. Must, mustnt析： 選A。因?yàn)榍鞍刖涫且蓡柧?，后半句為否定句，兩空都不能使用may/might 和must，應(yīng)而用can和cant。例

17、2：-Could I borrow your dictionary?Yes, of course you_.A. mightB. will C. canD. should析：選C。該句用can的委婉表達(dá)式could 來征求對方意見，could 和might通用，但回答時(shí)必須還成can或may，因此該題不選A.例3：_you mind my smoking here?A. ShouldB Could C. MightD. Would析：選D。征求對方意見我是否在這兒吸煙，語氣理應(yīng)委婉，所以應(yīng)選委婉的表達(dá)方式would you mind來征求對方意見。例4：-Must I start at onc

18、e? No, you_.A. needntB. mustnt C. cantD. wont析：A。由語境可知該答句表示“不必”，而mustnt表示“不準(zhǔn)、禁止”，不符合語境，顯然應(yīng)使用neednt表示“不必”，但肯定句回答繼續(xù)用must。例5：_you please help me with my English? A. WouldB. Do C. ShallD. Can析：A。次句表示請求對方意見，有“愿意 ”之意，而且又用于第二人稱，應(yīng)選用would。【中考演練】南海執(zhí)信中學(xué)初三英語備課組 (1) May I change the film here? No, you do that in
