情態(tài)動(dòng)詞小結(jié)

情態(tài)動(dòng)詞有：can（could），may（might），must，have to, shall（should），will（would），need, dare, ought to等。一． 情態(tài)動(dòng)詞can, may, must用法 ㈠基本用法 1.can ⑴ 會(huì)，能夠--Can you swim?--Yes, I can.--No, I can?t.⑵ 口語(yǔ)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(tài)動(dòng)詞，通常用在否定句和疑問(wèn)句中。)注意一：can 與be able to 都可以表示“能力”，區(qū)別是： ⑴ can只有現(xiàn)在和過(guò)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(shí)態(tài)

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(dòng)

I can swim but I am not able to cross the rough sea.有時(shí)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(guò)去式，表示過(guò)去的能力。

When I was young I could climb any tree in the forest.這時(shí)也可用was(were)able to ⑵ 用來(lái)代替can，婉轉(zhuǎn)地提出請(qǐng)求，想法，建議等?；卮疬@種情況下could引導(dǎo)的一般疑問(wèn)句時(shí)，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” 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(yè)對(duì)比，此must不表猜測(cè),兩回事。）注意四：must的過(guò)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(shuō)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(dòng)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(wèn)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.must表示“可能性”，只能用于肯定句，表推測(cè)：“一定是”，“準(zhǔn)是”，“必是”，“必定”。

It must be Jenny.小結(jié)表示“可能性”：

疑問(wèn)句：只能用can 否定句：cannot(can?t)“不可能”(反義詞是must“準(zhǔn)是”)may not“可能不”

肯定句：may “大概”

must“準(zhǔn)是”(反義詞是can?t)注意一: 在表示“可能性”時(shí)，凡是對(duì)過(guò)去事物的猜測(cè)，不管是疑問(wèn)．．句，否定句還是肯定句，都要用完成時(shí)。．．．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(xiàn)在或?qū)?lái)的可能性。若表示對(duì)過(guò)去事物 ．．．． 的猜測(cè)，則用完成時(shí)。③ He may come today.(tomorrow)He might come today.(tomorrow)(might語(yǔ)氣更不肯定，不是may的過(guò)去時(shí))④ She might have called for help.她可能大聲喊“救命”了。請(qǐng)翻譯下里句子：

1.Where can Wei Fang be? 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?

⑴ “must be +表語(yǔ)”的結(jié)構(gòu)，must表示肯定猜測(cè)時(shí)，含有“準(zhǔn)是”，“勢(shì)必”，“一定”等意義時(shí)，反義疑問(wèn)句用“isn?t/aren?t+主語(yǔ)” They must be hungry after the long walk, aren?t they? ⑵ “must have done” 表示猜測(cè)時(shí)，反義疑問(wèn)句用“haven?t/hasn?t +主語(yǔ)”或“didn?t+主語(yǔ)”

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(shí)間狀語(yǔ) ③ 重新組成一新句子 ④ 按新句子的時(shí)態(tài)造反義疑問(wèn)句

① You must have been to Beijing, ＿＿＿ ＿＿？

去掉must；無(wú)時(shí)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(shí)狀為yesterday;重組成 You finished your homework yesterday;故答案為：didn?t you 二．情態(tài)動(dòng)詞need的用法

⑴ need 表示“需要”，“必需”。作為情態(tài)動(dòng)詞，通常用在否定句和疑問(wèn)句中。

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(tài)動(dòng)詞dare的用法

⑴ dare 表示“敢” 作為情態(tài)動(dòng)詞，通常用于否定句，疑問(wèn)句或條件句中。dare 作為情態(tài)動(dòng)詞只有兩種形式:dare, dared(當(dāng)主語(yǔ)是第三人稱單數(shù)時(shí)，dare 不加s)① She dare not do so.(否定句)② Dare he do it?(一般疑問(wèn)句)③ How dare you say I?m unfair.(特殊疑問(wèn)句)④ Jump if you dare.有膽量你就跳。（條件句）⑵ 除了在“I dare say…” 這種習(xí)慣用語(yǔ)中，dare 在肯定句中作 情態(tài)動(dòng)詞的情況是很少的。（特殊用法，口語(yǔ)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(dòng)詞，其變化與一般動(dòng)詞相同。① Who dare to go? ② I don?t dare(to)ask her.問(wèn)：此句中的to 為什么可以省略？

答: 當(dāng)dare 作為①行為動(dòng)詞②在否定句中(兩個(gè)條件必須同時(shí)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(tài)動(dòng)詞shall和should的用法

④ Let?s have a rest, shall we?(Let?s 包括對(duì)方)對(duì)比：Let us have a rest, will you?(Let us 不包括對(duì)方)對(duì)于上述這類問(wèn)句的回答，沒(méi)有嚴(yán)格不變的肯定或否定模式。⑤ Shall I open the window?

第二篇：情態(tài)動(dòng)詞need用法小結(jié)

一、NEED與句子類型

（本條可參照ANY的用法。）NEED可用于：

1.否定句/含有否定意義的句子 1)否定句

含not/hardly/never/nobody等詞語(yǔ)。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.（否定轉(zhuǎn)移）

注：NEEDN’T的意思其實(shí)有三種，即不必要/不一定/不應(yīng)該，視具體語(yǔ)境而定。2)含有否定意義的句子

含only/but/all/before/than等詞語(yǔ)。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.疑問(wèn)句/表示疑問(wèn)的從句 1)疑問(wèn)句（包括否定疑問(wèn)句）Need he say it again? 2)表示疑問(wèn)的從句

I wonder whether/if I need see her.3.條件句

含if/unless等詞。

If he need come, he will.本條要點(diǎn)簡(jiǎn)單概括起來(lái)就是，NEED不能用于肯定句。以下的各種用法也遵循這條規(guī)則。

二、NEED與時(shí)態(tài) 1.現(xiàn)在時(shí)

NEED常用于現(xiàn)在時(shí)。You needn’t stay.2.將來(lái)時(shí)

You needn’t have your blood pressure taken tomorrow.3.過(guò)去時(shí)

NEED的過(guò)去式仍然是NEED。1)過(guò)去時(shí)間由一過(guò)去時(shí)間狀語(yǔ)表示 He need not come yesterday.2)過(guò)去時(shí)間由另一過(guò)去時(shí)動(dòng)詞表示。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：表示過(guò)去的NEED常用于間接引語(yǔ)中。（本條可參照must的用法）

三、NEED與虛擬語(yǔ)氣 1)NEED用于虛擬條件句

（本條可參照虛擬條件句的構(gòu)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：本條用法較為少見(jiàn)。

2)NEED單獨(dú)使用：NEEDN’T HAVE DONE（本條可參照SHOULDN’T HAVE DONE的用法。）You need not have worried.注：NEED HAVE DONE的形式較為少見(jiàn)

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.（實(shí)際上沒(méi)有做）

四、NEED與推測(cè)

NEEDN’T表示“不一定”。（本條可參照must/can的用法。）1)NEEDN’T+BE

It needn’t be hot in Florida now.對(duì)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.對(duì)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與問(wèn)句 1)反意疑問(wèn)句的構(gòu)成 You needn’t go, need you? 2)答句的構(gòu)成---Need he go?---Yes, he must/has to/needs to.---No, he needn’t.（本條可參照must的用法）

六、情態(tài)動(dòng)詞NEED與實(shí)義動(dòng)詞NEED 1)使用范圍

作為實(shí)義動(dòng)詞的NEED有人稱、數(shù)和時(shí)態(tài)的變化，使用范圍更為廣泛，不受句子類型和時(shí)態(tài)的限制。在肯定句、過(guò)去時(shí)和將來(lái)時(shí)的句子中，一般使用作為實(shí)義動(dòng)詞的NEED。

He needs to see a doctor straightaway.（此處needs to不能換做need，因?yàn)楸揪涫强隙ň洌?/p>

Will he need to start earlier? 注：

NEED TO BE DONE與NEED DOING可以互換，后者更為常用（這里的NEED均為實(shí)義動(dòng)詞）。2)含義差別

NEEDN’T HAVE DONE與DIDN’T NEED TO DO表示“不必要”的時(shí)候，在意義上有所差別，前者表示“本不必做??”，實(shí)際上已經(jīng)做了（NEED為情態(tài)動(dòng)詞）；后者單純地表示“不必做??”（NEED為實(shí)義動(dòng)詞）。

情態(tài)動(dòng)詞無(wú)論是表達(dá)“推測(cè)和可能性”，還是表達(dá)“虛擬”這一概念，只要是對(duì)過(guò)去已經(jīng)發(fā)生的事情進(jìn)行描述，一律用“情態(tài)動(dòng)詞+have done”這一結(jié)構(gòu)；對(duì)現(xiàn)在或?qū)?lái)的事情進(jìn)行描述，用“情態(tài)動(dòng)詞+動(dòng)詞或系動(dòng)詞原形”。例如：

（NMET2008山東，24）Thank you for all your hard work last week.I don’t think we ______ it without you.A.can manage

B.could have managed C.could manage D.can have managed 根據(jù)題干中所給出的時(shí)間last week可知我們已經(jīng)做完了工作，已經(jīng)完成，故排除A、C兩項(xiàng)，再結(jié)合could have done表示虛擬語(yǔ)氣以及與前面的I don’t think…，故說(shuō)話者想表達(dá)的意思是：離開(kāi)了你，我們本不可能完成這項(xiàng)工作。故答案為B項(xiàng)。

（二）表達(dá)虛擬語(yǔ)氣的情態(tài)動(dòng)詞

對(duì)過(guò)去的一種結(jié)果的假設(shè)或虛擬，用情態(tài)動(dòng)詞+have done這一結(jié)構(gòu)，常用的有以下幾個(gè)情態(tài)動(dòng)詞：

(1)should(not)/ ought(not)to have done本（不）應(yīng)該做某事，但卻沒(méi)有做或做了，含有責(zé)備或后悔之意。例如：

Thank you for all your hard work last week.I don’t think we ______ it without you.A.can manage

B.could have managed C.could manage

D.can have managed 【解析】根據(jù)題干中所給出的時(shí)間last week可知我們已經(jīng)做完了工作，已經(jīng)完成，故排除A、C兩項(xiàng)，再結(jié)合could have done表示虛擬語(yǔ)氣以及與前面的I don’t think?，故說(shuō)話者想表達(dá)的意思是：離開(kāi)了你，我們本不可能完成這項(xiàng)工作?！敬鸢浮緽(3)needn’t have done本沒(méi)有必要做某事但卻做了。要注意needn’t do則表達(dá)“沒(méi)有必要去做某事”，時(shí)間上應(yīng)該是現(xiàn)在或?qū)?lái)。例如： ①—Catherine, I have cleaned the room for you.—Thanks.You ________ it.I could manage it myself.A.needn’t do

B.needn’t have done

go to work tomorrow.A.can’t

He hesitated for a moment before kicking the ball, otherwise, he ________ a goal.A.had scored

B.scored

C.would score

D.would have scored 【解析】句中otherwise為含蓄條件，相當(dāng)于if he had not hesitated for a moment before kicking the ball，這是對(duì)過(guò)去的一種虛擬假設(shè)。【答案】D(5)might have done表示“本來(lái)可能??”，但實(shí)際上沒(méi)有發(fā)生的事。例如： What a pity!Considering his ability and experience, he ________ better.A.need have done

B.must have done C.can have done

D.might have done 【解析】真是可惜！考慮到他的能力和經(jīng)驗(yàn)，他本來(lái)可以做得更好的?！敬鸢浮緿

（三）表達(dá)“情感、態(tài)度、語(yǔ)氣” 等方面的情態(tài)動(dòng)詞 1.must表達(dá)“情感、態(tài)度、語(yǔ)氣”主要有以下用法：

(1)表示主觀的義務(wù)和必要，主要用于肯定句和疑問(wèn)句，意思為“必須??，得??，要??”；由must引起的疑問(wèn)句，肯定回答要用must或have to，否定回答要用needn’t或don’t have to,意思是“不必”。另外，must與have to都可以表示“必須”這一含義。must表示一種主觀的需要，而have to表示一種客觀的需要，意思是“不得不”，其否定形式是don’ have to。例如：-What sort of house do you want to have? Something big?--Well, it ______ be big--that's not important.A.mustn't

B.needn't

C.can't

D.won't

【解析】Something big?此處意為：Must it be big? 回答者的意思是：房子不必太大—那并不重要。

According to the air traffic rules, you ___ switch off your mobile phone before boarding.A.may

B.can

C.would

D.should 【解析】should此處表示根據(jù)交通法規(guī)應(yīng)盡的責(zé)任和義務(wù)。【答案】D(2)在虛擬條件句中用以加強(qiáng)假設(shè)語(yǔ)氣，表示“與將來(lái)事實(shí)相反的假設(shè)”，用 If+主語(yǔ)+ should +動(dòng)詞原形，當(dāng)“萬(wàn)一(會(huì))”講。這時(shí)可省略if，將should提到句首，變?yōu)榈寡b句式。請(qǐng)看下面的例子：

If it should rain(=Should it rain)tomorrow, I would stay at home.萬(wàn)一明天下雨的話，我就待在家里。再如：

________ fired, your health care and other benefits will not be immediately cut off.A.Would you be

第四篇：情態(tài)動(dòng)詞教案

情態(tài)動(dòng)詞

【考綱解讀】

情態(tài)動(dòng)詞與虛擬語(yǔ)氣有千絲萬(wàn)縷的聯(lián)系，它們往往放在一起考查。在近年高考題中，對(duì)情態(tài)動(dòng)詞的考查幾乎每年都有縱觀近幾年的高考題可以看出，高考對(duì)情態(tài)動(dòng)詞的考查熱點(diǎn)依次是：（1）推測(cè)和可能性；（2）“情態(tài)動(dòng)詞+have done”結(jié)構(gòu)表示猜測(cè)或表示虛擬語(yǔ)氣；（3）shall, should, can, must表示特定語(yǔ)氣。尤其是對(duì)“情態(tài)動(dòng)詞+have done”結(jié)構(gòu)的考查頻率較高。試題的情景設(shè)置往往生動(dòng)、真實(shí)，但考查的角度趨于細(xì)微化和綜合化，有效信息較為隱蔽，這就決定了情態(tài)動(dòng)詞題是難題之一。情態(tài)動(dòng)詞題每年都考，所以本專題在高考中的重要地位是顯而易見(jiàn)的。因而在復(fù)習(xí)中應(yīng)引起高度重視，且依筆者之見(jiàn)，來(lái)年高考中對(duì)情態(tài)動(dòng)詞考查的可能性依然非常大。【知識(shí)要點(diǎn)】

一、情態(tài)動(dòng)詞的語(yǔ)法特征

1.情態(tài)動(dòng)詞不能表示正在發(fā)生或已經(jīng)發(fā)生的事情，只表示期待或估計(jì)某事的發(fā)生。2.情態(tài)動(dòng)詞 除ought 和have 外，后面只能接不帶to 的不定式。3.情態(tài)動(dòng)詞沒(méi)有人稱、數(shù)的變化，即情態(tài)動(dòng)詞第三人稱單數(shù)不加-s。4.情態(tài)動(dòng)詞沒(méi)有非謂語(yǔ)形式，即沒(méi)有不定式，分詞等形式。

二、情態(tài)動(dòng)詞的基本用法 1.比較can 和be able to 1)can could 表示能力；可能(過(guò)去時(shí)用could)，只用于現(xiàn)在時(shí)和過(guò)去時(shí)(could)。be able to可以用于各種時(shí)態(tài)。

They will be able to tell you the news soon.他很快就能告訴你消息了。2)只用be able to中情況： 位于助動(dòng)詞后； 情態(tài)動(dòng)詞后；

表示過(guò)去某時(shí)刻動(dòng)作時(shí)； 用于句首表示條件；

表示成功地做了某事時(shí)，只能用was/were able to，不能用could。He was able to flee Europe before the war broke out.=He managed to flee Europe before the war broke out.戰(zhàn)爭(zhēng)爆發(fā)前，他就逃離歐洲了。

注意：could，在否定，疑問(wèn)句中表示推測(cè)或懷疑。表示提出委婉的請(qǐng)求（注意在回答中不可用could）。

—Could I have the television on? —Yes，you can./No，you can’t.He couldn’t be a bad man.他不大可能是壞人。2.比較may和might

1)表示允許或請(qǐng)求；表示沒(méi)有把握的推測(cè)；may 放在句首，表示祝愿。May God bless you!愿上帝保佑你！He might be at home.他有可能在家。

注意：might 表示推測(cè)時(shí)，不表示時(shí)態(tài)。只是可能性比may 小。

2)may/might as well，后面接不帶to 的不定式，意為“不妨，還是……好”。You may(might)as well tell me the truth.你還是對(duì)我說(shuō)實(shí)話好。3.比較have to和must

1)兩詞都是“必須”的意思，have to 表示客觀的需要，must 表示說(shuō)話人主觀上的看法，即主觀上的必要。

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(qǐng)來(lái)。(客觀上需要做這件事)

He said that they must work hard.他說(shuō)他們必須努力工作。（主觀上要做這件事）

2)have to有人稱、數(shù)、時(shí)態(tài)的變化，而must只有一種形式。

He had to look after his sister yesterday.昨天他不得不照看他的妹妹。3)在否定結(jié)構(gòu)中：

don’t have to 表示“不必”（可以不可以都行）；mustn’t表示“禁止” You don’t have to tell him about it.你不必把此事告訴他。You mustn’t tell him about it.你一定不要把這件事告訴他。4.must表示推測(cè)

1)must用在肯定句中表示較有把握的推測(cè)，意為“一定”。

2)must表對(duì)現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測(cè)時(shí)，must 后面通常接系動(dòng)詞be 的原形或行為動(dòng)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(duì)現(xiàn)在情況的推測(cè)判斷）He must be working in his office.他一定在辦公室工作呢。比較：He must be staying there.他現(xiàn)在肯定在那里。He must stay there.他必須待在那里。

3)must 表示對(duì)已發(fā)生的事情的推測(cè)時(shí)，must 要接完成式。I didn’t hear the phone.I must have been asleep.我剛才沒(méi)有聽(tīng)到電話，我想必是睡著了。

4)must表示對(duì)過(guò)去某時(shí)正發(fā)生的事情的推測(cè)，must 后面要接不定式的完成進(jìn)行式?！猈hy didn’t you answer my phone call?

—Well，I must have been sleeping，so I didn’t hear it.5)否定推測(cè)用can’t。

If Tom didn’t leave here until five o’clock，he can’t be home yet.如果湯姆五點(diǎn)才離開(kāi)這兒，他此時(shí)一定還未到家。5.表示推測(cè)的用法

can，could，may，might，must 皆可表示推測(cè)，其用法如下： 1)情態(tài)動(dòng)詞+動(dòng)詞原形

表示對(duì)現(xiàn)在或?qū)?lái)的情況的推測(cè)，此時(shí)動(dòng)詞通常為系動(dòng)詞。I don’t know where she is，she may be in Wuhan.我不知道她在哪兒，她可能在武漢。2)情態(tài)動(dòng)詞+動(dòng)詞現(xiàn)在進(jìn)行時(shí)

表示對(duì)現(xiàn)在或?qū)?lái)正在進(jìn)行的情況進(jìn)行推測(cè)。

At this moment，our teacher must be correcting our exam papers.這時(shí)，我們老師想必在批改試卷。

3)情態(tài)動(dòng)詞+動(dòng)詞完成時(shí)表示對(duì)過(guò)去情況的推測(cè)。

We would have finished this work by the end of next December.明年12月底前我們很可能已完成這項(xiàng)工作了。The road is wet.It must have rained last night.地是濕的，昨天晚上一定下雨了。

4)情態(tài)動(dòng)詞+動(dòng)詞的現(xiàn)在完成進(jìn)行時(shí)表示對(duì)過(guò)去正在發(fā)生事情的推測(cè)。Your mother must have been looking for you.你媽媽一定一直在找你。

5)推測(cè)的否定形式，疑問(wèn)形式用can’t，couldn’t表示。

Mike can’t have found his car，for he came to work by bus this morning.邁克一定還沒(méi)有找回他的車，因?yàn)樵缟纤亲财噥?lái)上班的。

注意：could，might表示推測(cè)時(shí)不表示時(shí)態(tài)，其推測(cè)的程度不如can，may。6.情態(tài)動(dòng)詞+have+過(guò)去分詞

1)may(might)have+done sth.can(could)have+done sth.表示過(guò)去，推測(cè)過(guò)去時(shí)間里可能發(fā)生的事情。

Philip may(might)have been hurt seriously in the car accident.飛利浦在那場(chǎng)車禍中有可能傷的很嚴(yán)重。

2)must have+done sth.對(duì)過(guò)去時(shí)間里可能發(fā)生的事情的推測(cè)，語(yǔ)氣較強(qiáng)，具有“肯定”“諒必”的意思。

—Linda has gone to work，but her bicycle is still here.—She must have gone by bus.3)ought to have done sth.／should have done sth.本應(yīng)該做某事，而事實(shí)上并沒(méi)有做。否定句表示“不該做某事而做了”。

He ought not to have thrown the old clothes away.（事實(shí)上已扔了。）ought to 在語(yǔ)氣上比should 要強(qiáng)。4)needn’t have done sth.本沒(méi)必要做某事 I dressed very warmly for the trip，but I needn’t have done so.The weather was hot.那次旅行，我穿的非常暖和，但我本沒(méi)有必要那么去做。天太熱了。5)would like to have done sth.本打算做某事

I would like to have read the article，but I was very busy then.我本想讀那本書，但我那時(shí)太忙了。7.should 和ought to

should 和ought to 都為“應(yīng)該”的意思，可用于各種人稱。—Ought he to go?

—Yes.I think he ought to.表示要求，命令時(shí)，語(yǔ)氣由 should（應(yīng)該），had better最好），must（必須）漸強(qiáng)。8.had better表示“最好”

had better 相當(dāng)于一個(gè)助動(dòng)詞，它只有一種形式，它后面要跟動(dòng)詞原形。had better do sth.最好干某事

had better not do sth.最好不干某事

had better have done sth.表示與事實(shí)相反的結(jié)果，意為“本來(lái)最好”。9.would rather表示“寧愿” would rather do 寧可干某事

would rather not do 寧可不干某事 would rather...than...寧愿……而不愿

還有would sooner，had rather，had sooner都表示“寧愿”“寧可”的意思。I would rather stay here than go home.=I would stay here rather than go home.我寧可待在這兒也不回家。

10.will和would

1)would like；would like to do=want to 想要，為固定搭配。Would you like to go with me?你想和我一塊兒去嗎？

2)Will you...? Would you like...?表示肯定含義的請(qǐng)求勸說(shuō)時(shí)，疑問(wèn)句 中一般用some，而不是any。

Would you like some cake?要蛋糕嗎？

3)否定結(jié)構(gòu)中用will，一般不用would，won’t you是一種委婉語(yǔ)氣。Won’t you sit down?你不坐嗎? 11.情態(tài)動(dòng)詞的回答方式

must和need相同:Yes,...must.No,...needn't/don't have to may和can could相同:Yes,...may/can/could.No,...mustn't/...'d better not/can't.shall:Yes,...can/may.No,...can't.should:Yes,...should.No,...shouldn't.will和would差不多:Yes,...do/will.No,...won't/thanks.典型例題

1）---Could I borrow your dictionary?---Yes,of course,you____.A.might B.will C.can D.should 答案C.could表示委婉的語(yǔ)氣,并不為時(shí)態(tài).答語(yǔ)中of course,表示肯定的語(yǔ)氣,允許某人做某事時(shí),用can和 may來(lái)表達(dá),不能用could或might.復(fù)習(xí)：will 與you連用,用來(lái)提出要求或下命令.should與you 連用,用來(lái)提出勸告.2）---Shall I tell John about it?---No,you ___.I've told him already.A.needn't B.wouldn't C.mustn't D.shouldn't 答案A.needn't 不必,不用.wouldn't 將不,mustn't 禁止、不能.shouldn't 不應(yīng)該.本題為不需要,不必的意思,應(yīng)用needn't.3）---Don't forget to come to my birthday party tomorrow.---______.A.I don't B.I won't C.I can't D.I haven't 答案B.will既可當(dāng)作情態(tài)動(dòng)詞,表請(qǐng)求、建議、也可作為實(shí)義動(dòng)詞表“意愿、意志、決心”,本題表示決心,選B.12.比較need和dare

一、need表示“需要”或“必須”，作情態(tài)動(dòng)詞時(shí)，僅用于否定句或疑問(wèn)句中，在肯定句中一般用must,have to,ought to，或should代替。多用在否定式或疑問(wèn)句中.1.Need I attend the meeting tomorrow?

我需要明天參加會(huì)議嗎? 2.You need not hand in the paper this week.這一周你不必交論文。

need 是一個(gè)情態(tài)動(dòng)詞，他的用法完全和其他情態(tài)動(dòng)詞一樣，但 need 還可當(dāng)作實(shí)義動(dòng)詞使用，這時(shí) need 就象其他動(dòng)詞一樣，有第三人稱，單復(fù)數(shù)，后面加帶 to 的動(dòng)詞等特性。1.I need a bike to go to school.我上學(xué)需要一輛自行車。2.Do you need a dictionary? 你需要詞典嗎? 3.She needs a necklace.她需要一條項(xiàng)鏈。

needn't + have + 過(guò)去分詞 表示過(guò)去做了沒(méi)必要做的事情。You needn't have taken it seriously.這件事情你不必太認(rèn)真。

二、Dare表示“敢”，Dare作情態(tài)動(dòng)詞時(shí)，主要用于疑問(wèn)句、否定句和條件從句中，一般不用在肯定句中。多用在否定或疑問(wèn)句中。1.The little girl dare not speak in public.小女孩不敢在公眾面前說(shuō)話。2.Dare you catch the little cat? 你敢抓小貓嗎? dare 除用作情態(tài)動(dòng)詞外，更多的是當(dāng)實(shí)義動(dòng)詞使用，用法同實(shí)義動(dòng)詞一樣，要考慮人稱，單復(fù)數(shù)，時(shí)態(tài)等。

1.Do you dare to walk in the dark? 你敢黑夜走路嗎？

2.He doesn't dare to tell the teacher what happened that day.他不敢告訴老師那天發(fā)生的事。

三、Dare和need常用作實(shí)義動(dòng)詞，有時(shí)態(tài)、人稱和數(shù)的變化，所不同的是，作實(shí)義動(dòng)詞時(shí)，在肯定句中，dare后面通常接帶to的不定式，在否定和疑問(wèn)句中，dare后面可接帶to或不帶to的不定式。如：

I dare to swim across this river.He does not dare(to)answer.Don't you dare(to)touch it!I wondered he dare(to)say that.He needs to finish it this evening.另外need 的被動(dòng)含義：need，want，require，worth（形容詞）后面接doing，也 可以表示被動(dòng)：need doing=need to be done Shall用于第一人稱,表示征求對(duì)方的意愿.如：What shall we do this evening? 2.Shall用于第一、第三人稱疑問(wèn)句中,表示說(shuō)話人征求對(duì)方的意見(jiàn)或向?qū)Ψ秸?qǐng)示.如：Shall we begin our lesson? When shall he be able to leave the hospital? 3.Shall用于第二、第三人稱,表示說(shuō)話人給對(duì)方命令、警告、允諾或威脅.如：You shall fail if you don't work harder.（警告）He shall have the book when I finish reading.（允諾）He shall be punished.（威脅）
