第三篇：情態動詞教案

情態動詞

【考綱解讀】

情態動詞與虛擬語氣有千絲萬縷的聯系，它們往往放在一起考查。在近年高考題中，對情態動詞的考查幾乎每年都有縱觀近幾年的高考題可以看出，高考對情態動詞的考查熱點依次是：（1）推測和可能性；（2）“情態動詞+have done”結構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“情態動詞+have done”結構的考查頻率較高。試題的情景設置往往生動、真實，但考查的角度趨于細微化和綜合化，有效信息較為隱蔽，這就決定了情態動詞題是難題之一。情態動詞題每年都考，所以本專題在高考中的重要地位是顯而易見的。因而在復習中應引起高度重視，且依筆者之見，來年高考中對情態動詞考查的可能性依然非常大。【知識要點】

一、情態動詞的語法特征

1.情態動詞不能表示正在發生或已經發生的事情，只表示期待或估計某事的發生。2.情態動詞 除ought 和have 外，后面只能接不帶to 的不定式。3.情態動詞沒有人稱、數的變化，即情態動詞第三人稱單數不加-s。4.情態動詞沒有非謂語形式，即沒有不定式，分詞等形式。

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

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.戰爭爆發前，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。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、時態的變化，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)在否定結構中：

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表對現在的狀態或現在正發生的事情的推測時，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.他現在肯定在那里。He must stay there.他必須待在那里。

3)must 表示對已發生的事情的推測時，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生的事情的推測，must 后面要接不定式的完成進行式。—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)情態動詞+動詞原形

表示對現在或將來的情況的推測，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)情態動詞+動詞現在進行時

表示對現在或將來正在進行的情況進行推測。

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)情態動詞+動詞的現在完成進行時表示對過去正在發生事情的推測。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，因為早上他是坐公共汽車來上班的。

注意：could，might表示推測時不表示時態，其推測的程度不如can，may。6.情態動詞+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重。

2)must have+done sth.對過去時間里可能發生的事情的推測，語氣較強，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.本應該做某事，而事實上并沒有做。否定句表示“不該做某事而做了”。

He ought not to have thrown the old clothes away.（事實上已扔了。）ought to 在語氣上比should 要強。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（應該），had better最好），must（必須）漸強。8.had better表示“最好”

had better 相當于一個助動詞，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.表示與事實相反的結果，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)否定結構中用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.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,不能用could或might.復習：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 不應該.本題為不需要,不必的意思,應用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既可當作情態動詞,表請求、建議、也可作為實義動詞表“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 是一個情態動詞，他的用法完全和其他情態動詞一樣，但 need 還可當作實義動詞使用，這時 need 就象其他動詞一樣，有第三人稱，單復數，后面加帶 to 的動詞等特性。1.I need a bike to go to school.我上學需要一輛自行車。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真。

二、Dare表示“敢”，Dare作情態動詞時，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 除用作情態動詞外，更多的是當實義動詞使用，用法同實義動詞一樣，要考慮人稱，單復數，時態等。

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生的事。

三、Dare和need常用作實義動詞，有時態、人稱和數的變化，所不同的是，作實義動詞時，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對方請示.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）

Complete the following tasks.（A級 識記類）（C層學生展示，B、A層學生補充）

一、何謂“情態動詞”？

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

二、情態動詞的特點 1.沒有人稱和數的變化。2.有些情態動詞有過去式的變化: e.g.will → would , can → could , may→ might , dare → dared

三、情態動詞的否定形式

情態動詞+ not +動詞原形can not: can't , must not: mustn't , need not : needn't Cooperation and Discussion 【合作探究、討論解疑】

五、情態動詞的解題例析

(1)認真審題，結合所給出的語境，正確把握說話者的語氣、情感、態度、觀點等。

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

情態動詞無論是表達“推測和可能性”，還是表達“虛擬”這一概念，只要是對過去已經發生的事情進行描述，一律用“情態動詞+have done”這一結構；對現在或將來的事情進行描述，用“情態動詞+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 根據題干中所給出的時間last week可知我們已經做完了工作，已經完成，故排除A、C兩項，再結合could have done表示虛擬語氣以及與前面的I don’t think…，故說話者想表達的意思是：離開了你，我們本不可能完成這項工作。故答案為B項。

Expansion and Improvement【知識拓展、能力提升】（D級 拓展類）（C、B層學生展示，A層學生補充）

★下面我們來看看常考的一些情態動詞★

以下試題均來源于往年的高考試題，具有很強的針對性

(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生了。例如：

—She looks very happy.She ______ have passed the exam.—I guess so.It’s not difficult after all.A.should

B.could

C.must

D.might 【解析】句意為：她看上去很高興，一定是通過了考試。【答案】C(2)should(not)/ ought(not)to在中表示根據常規或常識推測，表示“某事應該或不應該發生”，語氣比must或can’t / couldn’t稍弱。例如：—How’s your tour around the North Lake? Is it beautiful? —It ________ be, but it is now heavily polluted.A.will

B.would

C.should

D.must 【解析】should此處表示推測，意為“應該”。【答案】C ②There _________ be any difficulty about passing the road test since you have practiced a lot in the driving school.A.mustn’t

B.shan’t

C.shouldn’t

D.needn’t 【解析】句意：既然你在駕校進行了大量訓練，那么通過道路測試按理不應該有困難。【答案】C(3)can, could表達推測時，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!

A.wouldn’t

B.can’t

C.mustn’t

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

B.wouldn’t

C.shouldn’t

D.needn’t ③It is usually warm in my hometown in March, but it _____ be rather cold sometime.A.must

B.can

C.should

D.would ④Peter ____ be really difficult at times even though he’s a nice person in general.A.shall

B.should

C.can

D.must 【解析】①② 兩個考題中can用于中表示否定的推測，意為：不可能，一定不會； ③④兩個考題中can表示理論上的可能性，翻譯為：有時候會??。【答案】① B ② A

③ B ④ C(4)may(not)/ might(not)表達一種不太把握的推測，意為“或許，可能”；might的語氣比may較婉轉。例如：

① Liza ___ well not want to go on the trip---she hates traveling.A.will

B.can

C.must

D.may 【解析】may well為固定搭配，意為：很可能，極有可能。【答案】Ｄ

②

Although this ____ sound like a simple task, great care is needed.A.must

B.may

C.shall

D.should 【解析】這聽起來或許是一項簡單的任務，但卻需要極大的細心。【答案】B ③—I can’t find my purse anywhere.—You __ have lost it while shopping.A.may

B.can

C.should

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

（二）表達虛擬語氣的情態動詞

對過去的一種結果的假設或虛擬，用情態動詞+have done這一結構，常用的有以下幾個情態動詞：

(1)should(not)/ ought(not)to have done本（不）應該做某事，但卻沒有做或做了，含有責備或后悔之意。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】根據題干中所給出的時間last week可知我們已經做完了工作，已經完成，故排除A、C兩項，再結合could have done表示虛擬語氣以及與前面的I don’t think?，故說話者想表達的意思是：離開了你，我們本不可能完成這項工作。【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“沒有必要去做某事”，時間上應該是現在或將來。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

C.mustn’t do

D.shouldn’t have done 【解析】根據句意可知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)會發生某事，但卻（發生了）或沒有發生。常用于虛擬條件句或含蓄虛擬條件引導的虛擬語氣，表示對過去所發生事情結果的假設。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。【答案】D(5)might have done表示“本來可能??”，但實際上沒有發生的事。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驗，他本來可以做得更好的。【答案】D

（三）表達“情感、態度、語氣” 等方面的情態動詞 1.must表達“情感、態度、語氣”主要有以下用法：

(1)表示主觀的義務和必要，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應該，表示“責任和義務”。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此處表示根據交通法規應盡的責任和義務。【答案】D(2)在虛擬條件句中用以加強假設語氣，表示“與將來事實相反的假設”，用 If+主語+ should +動詞原形，當“萬一(會)”講。這時可省略if，將should提到句首，變為倒裝句式。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

C.Could you be

D.Might you be 【解析】句意：萬一你被解雇，給你的醫療救助和其它方面的福利也不會被取消。【答案】B(3)should還可以用來表示說話人對某事不能理解、趕到意外、驚異等意思，譯為“竟然，竟會”。例如：

You can’t imagine that a well-behaved gentleman _____ be so rude to a lady.A.might

B.need

C.should

D.would 【解析】句意：你想象不到這么一個表現良好的紳士竟然會對一個女士這么粗魯。【答案】C 3.shall(1)shall用于第一和第三人稱，常用于疑問句中，用來征求對方意見。例如： ①—What’s the name? —Khulaifi._________ I spell it for you?

A.Shall

B.Would

C.Can

D.Might 【答案】A

(2)用于第二和第三人稱，表示“命令、威脅、警告、允諾、”等。例如： —Excuse me.But I want to use your computer to type a report.—You _____have my computer if you don’t take care of it.A.shan’t
