haveto用can打聽(tīng)第三方是否能參加聚會(huì)，表示一種可能性。用can發(fā)出邀請(qǐng)接受邀請(qǐng)拒絕邀請(qǐng)說(shuō)明理由Observe

情態(tài)動(dòng)詞can用法1.can表示能力，表示“能，會(huì)”。eg.Shecanplaythepiano.2.can表示許可，表示“可以”。相當(dāng)于may（比may更口語(yǔ)化）；此外，could的語(yǔ)氣更為委婉。eg.MayIcomein?Couldyouhelpme?can表示邀請(qǐng)時(shí)常用一般疑問(wèn)句句式，結(jié)構(gòu)為:Can+主語(yǔ)+動(dòng)詞原形+其他？

can表示邀請(qǐng)的用法CanyoucometomypartyonSaturday?Sure,I’dloveto.Sorry,Imuststudyforamathtest.Canyougotothemoviestomorrownight?Sure.Thatsoundsgreat.I’mafraidnot.Ihavetheflu.Canhegototheparty?No,hecan’t.Hehastohelphisparents.Canshegotothebaseballgame?No.she’snotavailable.Shemustgotothedoctor.Cantheygotothemovies?No,they’renotfree.Theymighthavetomeettheirfriends.Howdoweacceptorrefuseaninvitation?(1)常見(jiàn)表示接受邀請(qǐng)的回答：①Sure,I’dloveto.②Yes,I’dloveto.③Sure.Thatsoundsgreat.can表示邀請(qǐng)時(shí)，其回答分為兩類。一類是表示接受邀請(qǐng)，另一類是表示拒絕邀請(qǐng)。(2)常見(jiàn)表示拒絕邀請(qǐng)的回答：①Sorry.I’mnotavailable.②I’msorry.I’mnotfreethisweekend.Ihaveto...③I’dloveto,butI’mafraidIcan’t.Ihaveto...拓展--其他情態(tài)動(dòng)詞1.must/haveto的用法(1)must表示“必須”或“應(yīng)當(dāng)”，其否定式為mustn't。

以must開(kāi)頭的一般疑問(wèn)句的肯定回答為：Yes,主語(yǔ)＋must;

其否定回答為：No,主語(yǔ)＋needn't.eg.--MustIfinishmyschoolworktoday?我今天必須完成我的功課嗎？

--No,youneedn’t.不，你不需要。(2)haveto也表示“必須，不得不”。一般情況下，must表示說(shuō)話人的主觀看法，而haveto表示客觀需要。(3)注意：must還可以表示推測(cè)

，“一定”eg.Itmustbedelicious.它一定很好吃▲4.haveto的用法(1)haveto的意思是“必須、不得不”,往往強(qiáng)調(diào)由于客觀原因而必須做某事。have(has)to后面要用動(dòng)詞原形。當(dāng)主語(yǔ)為第三人稱單數(shù)時(shí)用hasto，當(dāng)句子是過(guò)去時(shí)用hadto。如：HehastoworkonSunday.

他不得不在周日工作。(2)haveto的否定句句型：主語(yǔ)

+

don’t

/

didn’t

/

doesn’t

/

won’t+

haveto

+

動(dòng)詞原形。如：Youdon’thavetowalksofast.

你不必走那么快?！?.haveto的用法(3)haveto的疑問(wèn)句句型：Do

/

Does

/

Did

/

Will+主語(yǔ)+haveto+動(dòng)詞原形。如：—Didhehavetoaskthequestion?

—他非要問(wèn)那個(gè)問(wèn)題嗎？—Yes,hedid.—是的?！狽o,hedidn’t(haveto).—不?！?.must

與

havetomust表示主觀“必須”；haveto表示客觀客觀需要，即“不得不”。如：

Idon’tlikethisTVset.Imustbuyanewone.

ThisTVsetdoesn’twork.Wehavetobuyanewone.

Youmustgetupatfivetomorrow.

We(will)havetogetupearlytomorrow.【拓展】表示同意邀請(qǐng)的回答還可用：Yes,I’dlove/liketo.Sure,itsoundsgreat.Certainly,I’dlove/liketo.Sure,I’dlove/liketo.Thanksforyourinvitation.Thanksforaskingme.如果拒絕邀請(qǐng)，答語(yǔ)可用：I’msorry.I’mnotfree/available.Thanksforyourinvitation.Imighthaveto/must...Sorry,I’mafraidnot.Imighthaveto/must...Sorry,Ican’t.Imighthaveto/must...I’dloveto,butIhaveto…No,Ican’t.I’mgoingto...Thankyouforaskingme.But....Iamafraidnot,I...【拓展】其他提出邀請(qǐng)的句型：Could/Willyou…?Wouldyouliketo...?How/Whatabout...?Whynot...?Let’s...Ihopeyou...can表示“做某事的可能性”，意為“可以”(可用來(lái)詢問(wèn)打聽(tīng)第三方能否參加某項(xiàng)活動(dòng))。對(duì)這種情況下can引起的問(wèn)句仍由can或can’t作肯定或否定回答。如課本中的句子Canhegototheparty?肯定答語(yǔ)：Yes,he/she/theycan.否定答語(yǔ)：No,he/she/theycan’t.或No,he/sheis/theyarenotavailable.等。can表示可能性—CanAlicegotothemovieswithustonight?—Yes,shecan./

No,she’snotavailable.Shehastolookafterhersister.e.g.—Can

hecomeherebeforeninetomorrowmorning?—No,hecan’t.Hehastogotothemusicclubfirst.Theymighthavetomeettheirfriends.might在此表示推測(cè)和可能性。它的可能性比may小。情態(tài)動(dòng)詞might用法e.g.Shemightnotwantto

comewithus.

她可能不想和我們一起走。Howlongmightthetraveltake?這次旅行需要多長(zhǎng)時(shí)間？Dadmightknowhowtostartthatmachine.爸爸也許知道如何發(fā)動(dòng)那臺(tái)機(jī)器。2.may/might的用法(1)may也可表示邀請(qǐng)，注意其否定回答為“No,主語(yǔ)＋mustn't/can’t”?！狹ayIgonow?——我現(xiàn)在可以走了嗎？—No,youmustn't.——不，你不能走。(2)may表示說(shuō)話人的猜測(cè)，認(rèn)為某一事情可能發(fā)生，其否定結(jié)構(gòu)為maynot,其過(guò)去式為mightnot。eg.Thenewspapersaysthatitmightrain．(3)might表可能，其語(yǔ)氣比may更委婉，更加不確定。Hisparentsmightcometoday.他父母今天可能會(huì)來(lái)。一、單項(xiàng)選擇1.Dirtyairandwaterareharmful.They
