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(dòng)詞的考查幾乎每年都有縱觀近幾年的高考題可以看出，高考對情態(tài)動(dòng)詞的考查熱點(diǎn)依次是：（1）推測和可能性；（2）“情態(tài)動(dòng)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(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(dòng)詞考查的可能性依然非常大?！局R(shí)要點(diǎn)】

一、情態(tài)動(dòng)詞的語法特征

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)詞沒有非謂語形式，即沒有不定式，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(過去時(shí)用could)，只用于現(xiàn)在時(shí)和過去時(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(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(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

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(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(shí)，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(shí)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?！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(shí)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(dòng)詞+動(dòng)詞原形

表示對現(xiàn)在或?qū)淼那闆r的推測，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(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(dòng)詞+動(dòng)詞的現(xiàn)在完成進(jìn)行時(shí)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(shí)不表示時(shí)態(tài)，其推測的程度不如can，may。6.情態(tài)動(dòng)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(shí)間里可能發(fā)生的事情。

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

2)must have+done sth.對過去時(shí)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(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?！狾ught he to go?

—Yes.I think he ought to.表示要求，命令時(shí)，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(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(shí)，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(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表示委婉的語氣,并不為時(shí)態(tài).答語中of course,表示肯定的語氣,允許某人做某事時(shí),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(dòng)詞,表請求、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(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(dòng)詞時(shí)，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(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）
