情態(tài)動詞的特征：

1.在形式上，情態(tài)動詞沒有實(shí)義動詞的各種變化。

2.在意義上，大多數(shù)情態(tài)動詞有多個意義。

3.在用法上，情態(tài)動詞與助動詞一樣，須后接動詞原形。

特別提醒：情態(tài)動詞表推測時

1、can只能用于否定句和疑問句

2、must只能用于肯定句（它的否定句和疑問句其實(shí)就用can來代替了）

3、如句中有情態(tài)動詞 + 完成時，定是對過去的推測。

4、句中如有表示不肯定的話語，如：I am not sure;I don’t know 之類，常選may /might的各種形式

4.記住下面幾組表示反勸的特殊的表推測的形式

1).could + have + PP表示本來能做到，但事實(shí)上沒有做到。He could have finished the task on time, but the heavy snow came.2).couldn’t +have + PP表示本來不能做到，但已經(jīng)做到了。She could not have covered the whole distance, but in fact she arrived ahead of time.3)needn’t + have + pp表示本不必做的，但已經(jīng)做到了。She needn’t have attended the meeting yesterday, but she did.4.)should/ought to +have + PP表示 該做而沒有做 The plant is dead.I should/ought to have given ot more water.5)shouldn’t/ oughtn’t to +have + PP表示 不該做而做了。You oughtn’t to / shouldn’t have taken her bike without permission.5.記住下面對比：

must只能用于肯定句（它的否定句和疑問句其實(shí)就用can來代替了）

1.must + have + PP 表示對過去肯定的推測，譯為“一定是，準(zhǔn)是” The road is wet.It must have rained yesterday.2.can + have + PP 表示對過去的推測（限于問句中）Can she have said so? 他可能這樣說嗎？

3.can’t + have + PP 表示對過去的否定推測 He cannot have said such a foolish thing.情態(tài)動詞表推測的反意疑問句

情態(tài)動詞表推測的反意疑問句，簡單來說，就是以情態(tài)動詞后的時態(tài)為淮，如句子里有明確的時間狀語，則以其為準(zhǔn)。以 must 為例：

eg.1.You must be hungry now, aren’t you?

2.He must be watching TV , isn’t he ? Tom must have lived her for a long time, hasn’t he ?

4.She must have arrived yesterday, didn’t she?

注：如選擇題中（以She must have arrived yesterday, didn’t she？為例）既有didn’t she又有hasn’t she則以didn’t she？為最佳答案

一、何謂“情態(tài)動詞”？

情態(tài)動詞主要用來表示說話人的情感、態(tài)度等，是中學(xué)英語語法的重點(diǎn)，也是高考的熱點(diǎn)，是單項(xiàng)填空必考的一個知識點(diǎn)。情態(tài)動詞在近五年高考中主要考查四點(diǎn)：情態(tài)動詞表示推測和可能性的用法；情態(tài)動詞與虛擬語氣；情態(tài)動詞的表達(dá)“情感、態(tài)度、語氣等”，情態(tài)動詞表示 “必要性”等方面的用法。

(2)認(rèn)真思考所給選項(xiàng)中情態(tài)動詞的基本特征和用法，并結(jié)合語境推敲答案。(3)要注意把握時間概念。

情態(tài)動詞無論是表達(dá)“推測和可能性”，還是表達(dá)“虛擬”這一概念，只要是對過去已經(jīng)發(fā)生的事情進(jìn)行描述，一律用“情態(tài)動詞+have done”這一結(jié)構(gòu)；對現(xiàn)在或?qū)淼氖虑檫M(jìn)行描述，用“情態(tài)動詞+動詞或系動詞原形”。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表示虛擬語氣以及與前面的I don’t think…，故說話者想表達(dá)的意思是：離開了你，我們本不可能完成這項(xiàng)工作。故答案為B項(xiàng)。

★下面我們來看看常考的一些情態(tài)動詞★

以下試題均來源于往年的高考試題，具有很強(qiáng)的針對性

(1)must表示推測，意為“一定??”，只能用于肯定句中。must have done意為：一定做過某事或某事肯定發(fā)生了。例如：

B.shan’t

C.shouldn’t

D.needn’t 【解析】句意：既然你在駕校進(jìn)行了大量訓(xùn)練，那么通過道路測試按理不應(yīng)該有困難。【答案】C(3)can, could表達(dá)推測時，一般用于疑問句和否定句中；can用于肯定句中表示一種理論上的可能性，并不牽涉是否真的會發(fā)生，在這種用法中can只能與動詞原形連用；could用于肯定句中，語氣比may/ might更弱。例如： ①You ______ be hungry already — you had lunch only two hours ago!

C.mustn’t

D.needn’t ②She ______ have left school, for her bike is still here.A.can’t

C.should

D.would 【解析】結(jié)合語境可知，回答者是在提醒對方：或許購物時把錢包丟了。【答案】A

（二）表達(dá)虛擬語氣的情態(tài)動詞

對過去的一種結(jié)果的假設(shè)或虛擬，用情態(tài)動詞+have done這一結(jié)構(gòu)，常用的有以下幾個情態(tài)動詞：

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

—I’m sorry.I _________at you the other day.—Forget it.I was a bit out of control myself.A.shouldn’t shout

B.shouldn’t have shouted C.mustn’t shout

C.mustn’t have shouted 【解析】對不起，我那天本不應(yīng)該對你大喊大叫的。【答案】B(2)could have done本來能夠做某事但未做。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表示虛擬語氣以及與前面的I don’t think?，故說話者想表達(dá)的意思是：離開了你，我們本不可能完成這項(xiàng)工作。【答案】B(3)needn’t have done本沒有必要做某事但卻做了。要注意needn’t do則表達(dá)“沒有必要去做某事”，時間上應(yīng)該是現(xiàn)在或?qū)怼＠纾?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

C.mustn’t do

D.shouldn’t have done 【解析】根據(jù)句意可知Catherine對對方為她打掃了房間表示感謝并提到對方不必為她打掃房間。【答案】B ② The boss has given everyone a special holiday, so we

go to work tomorrow.A.can’t

B.mustn’t

C.needn’t

D.shouldn’t 【解析】老板給所有的員工放了假，所以我們明天不必再去上班。【答案】C(4)would(not)have done本來(不)會發(fā)生某事，但卻（發(fā)生了）或沒有發(fā)生。常用于虛擬條件句或含蓄虛擬條件引導(dǎo)的虛擬語氣，表示對過去所發(fā)生事情結(jié)果的假設(shè)。例如：

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，這是對過去的一種虛擬假設(shè)。【答案】D(5)might have done表示“本來可能??”，但實(shí)際上沒有發(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)，他本來可以做得更好的。【答案】D

（三）表達(dá)“情感、態(tài)度、語氣” 等方面的情態(tài)動詞 1.must表達(dá)“情感、態(tài)度、語氣”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句，意思為“必須??，得??，要??”；由must引起的疑問句，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。

【答案】B

(2)must的否定形式mustn’t表示禁止，意思是“不能，不許”。例如： When I was young, I was told that I ______ play with matches

A.wouldn't

B.needn't

C.mustn't

D.daren't 【解析】當(dāng)我年輕的時候，（家人）就一直告誡我千萬不要玩火柴。【答案】C(3)must用于條件句或疑問句中，可以用來表示責(zé)備、抱怨的感情色彩，意思為“偏要，硬要、干嘛”。例如： ①—May I smoke here ? —If you ____, choose a seat in the smoking section.A.should

B.could

C.may

D.must ②John, look at the time.___________ you play the piano at such a late hour? A．Must

B．Can

C．May

D．Need 【解析】must在這兩道試題中均表示“非得，偏要”。【答案】① D

② A 2.should(1)should應(yīng)該，表示“責(zé)任和義務(wù)”。例如：

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)語氣，表示“與將來事實(shí)相反的假設(shè)”，用 If+主語+ should +動詞原形，當(dāng)“萬一(會)”講。這時可省略if，將should提到句首，變?yōu)榈寡b句式。請看下面的例子：

If it should rain(=Should it rain)tomorrow, I would stay at home.萬一明天下雨的話，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

B.Should you be

第三篇：情態(tài)動詞教案

情態(tài)動詞

【考綱解讀】

情態(tài)動詞與虛擬語氣有千絲萬縷的聯(lián)系，它們往往放在一起考查。在近年高考題中，對情態(tài)動詞的考查幾乎每年都有縱觀近幾年的高考題可以看出，高考對情態(tài)動詞的考查熱點(diǎn)依次是：（1）推測和可能性；（2）“情態(tài)動詞+have done”結(jié)構(gòu)表示猜測或表示虛擬語氣；（3）shall, should, can, must表示特定語氣。尤其是對“情態(tài)動詞+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、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)動詞題是難題之一。情態(tài)動詞題每年都考，所以本專題在高考中的重要地位是顯而易見的。因而在復(fù)習(xí)中應(yīng)引起高度重視，且依筆者之見，來年高考中對情態(tài)動詞考查的可能性依然非常大。【知識要點(diǎn)】

一、情態(tài)動詞的語法特征

1.情態(tài)動詞不能表示正在發(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)動詞 除ought 和have 外，后面只能接不帶to 的不定式。3.情態(tài)動詞沒有人稱、數(shù)的變化，即情態(tài)動詞第三人稱單數(shù)不加-s。4.情態(tài)動詞沒有非謂語形式，即沒有不定式，分詞等形式。

二、情態(tài)動詞的基本用法 1.比較can 和be able to 1)can could 表示能力；可能(過去時用could)，只用于現(xiàn)在時和過去時(could)。be able to可以用于各種時態(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： 位于助動詞后； 情態(tài)動詞后；

表示過去某時刻動作時； 用于句首表示條件；

表示成功地做了某事時，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)爭爆發(fā)前，他就逃離歐洲了。

注意：could，在否定，疑問句中表示推測或懷疑。表示提出委婉的請求（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)表示允許或請求；表示沒有把握的推測；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 表示推測時，不表示時態(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.你還是對我說實(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）

2)have to有人稱、數(shù)、時態(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

1)must用在肯定句中表示較有把握的推測，意為“一定”。

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，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。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 表示對已發(fā)生的事情的推測時，must 要接完成式。I didn’t hear the phone.I must have been asleep.我剛才沒有聽到電話，我想必是睡著了。

4)must表示對過去某時正發(fā)生的事情的推測，must 后面要接不定式的完成進(jìn)行式。—Why didn’t you answer my phone call?

—Well，I must have been sleeping，so I didn’t hear it.5)否定推測用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)才離開這兒，他此時一定還未到家。5.表示推測的用法

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

表示對現(xiàn)在或?qū)淼那闆r的推測，此時動詞通常為系動詞。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)動詞+動詞現(xiàn)在進(jìn)行時

表示對現(xiàn)在或?qū)碚谶M(jìn)行的情況進(jìn)行推測。

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

3)情態(tài)動詞+動詞完成時表示對過去情況的推測。

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)動詞+動詞的現(xiàn)在完成進(jìn)行時表示對過去正在發(fā)生事情的推測。Your mother must have been looking for you.你媽媽一定一直在找你。

5)推測的否定形式，疑問形式用can’t，couldn’t表示。

Mike can’t have found his car，for he came to work by bus this morning.邁克一定還沒有找回他的車，因?yàn)樵缟纤亲财噥砩习嗟摹?/p>

注意：could，might表示推測時不表示時態(tài)，其推測的程度不如can，may。6.情態(tài)動詞+have+過去分詞

1)may(might)have+done sth.can(could)have+done sth.表示過去，推測過去時間里可能發(fā)生的事情。

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

2)must have+done sth.對過去時間里可能發(fā)生的事情的推測，語氣較強(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 在語氣上比should 要強(qiáng)。4)needn’t have done sth.本沒必要做某事 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，語氣由 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)于一個助動詞，它只有一種形式，它后面要跟動詞原形。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...?表示肯定含義的請求勸說時，疑問句 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是一種委婉語氣。Won’t you sit down?你不坐嗎? 11.情態(tài)動詞的回答方式

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表示委婉的語氣,并不為時態(tài).答語中of course,表示肯定的語氣,允許某人做某事時,用can和 may來表達(dá),不能用could或might.復(fù)習(xí)：will 與you連用,用來提出要求或下命令.should與you 連用,用來提出勸告.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)動詞,表請求、建議、也可作為實(shí)義動詞表“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)動詞時，僅用于否定句或疑問句中，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句中.1.Need I attend the meeting tomorrow?

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

need 是一個情態(tài)動詞，他的用法完全和其他情態(tài)動詞一樣，但 need 還可當(dāng)作實(shí)義動詞使用，這時 need 就象其他動詞一樣，有第三人稱，單復(fù)數(shù)，后面加帶 to 的動詞等特性。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 + 過去分詞 表示過去做了沒必要做的事情。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)動詞時，主要用于疑問句、否定句和條件從句中，一般不用在肯定句中。多用在否定或疑問句中。1.The little girl dare not speak in public.小女孩不敢在公眾面前說話。2.Dare you catch the little cat? 你敢抓小貓嗎? dare 除用作情態(tài)動詞外，更多的是當(dāng)實(shí)義動詞使用，用法同實(shí)義動詞一樣，要考慮人稱，單復(fù)數(shù)，時態(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)義動詞，有時態(tài)、人稱和數(shù)的變化，所不同的是，作實(shí)義動詞時，在肯定句中，dare后面通常接帶to的不定式，在否定和疑問句中，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 的被動含義：need，want，require，worth（形容詞）后面接doing，也 可以表示被動：need doing=need to be done Shall用于第一人稱,表示征求對方的意愿.如：What shall we do this evening? 2.Shall用于第一、第三人稱疑問句中,表示說話人征求對方的意見或向?qū)Ψ秸埵?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,表示說話人給對方命令、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）
