情态动词haveto与其他的情态动词如can,may,must和should”

不同。

（1）这4个情态动词没有人称的变化,而haveto有。它的第三人称单数为“hasto”。

You/

Heshouldstudyhard.你/他应该好好学习。

Hehastostudyhard.

他不得不好好学习。haveto的用法（2）这4个情态动词在一般疑问句中将它们放在句首,在否定句中直接在他们后边加not即可。我们以can为例:Canhegowithus他能和我们一起去吗？Hecan’tgowithus.他不能和我们一起去。而haveto要加助动词do,does或did才可能完成其疑问、否定句。试将下面三句话分别写成（1）一般疑问句，并作肯定回答。（2）否定句。a.Theyhavetogototheparty.DotheyhavetogotothepartyYes,theydo.Theydon’thavetogototheparty.b.Hehastogotoseethedoctor.DoeshehavetogotoseethedoctorYes,hedoes.Hedoesn’thavetogotoseethedoctor.c.Shehadtostudyforamathtestyesterday.DidshehavetostudyforamathyesterdayYes,shedid.Shedidn’thavetostudyforamathyesterday.haveto与must

二者都有“必须”之意，但haveto

表示“客观上的需要”，有人称和时态的变化，否定形式为don’t/doesn’t/didn’thaveto(没必要)；must表示“主观上的要求”，无人称和时态的变化，否定回答一般用needn’t或don'thaveto(不必)。mustn’t表示“禁止”。如：比一比

Wehavetowearwarmclothesinwinter.

冬天我们不得不穿上暖和的衣服。(客观需要)ImustfinishmyhomeworkfirstbeforeIwatchTV.看电视前我必须先完成作业。(主观要求)Youdon'thavetotellhimaboutit.你不一定要把此事告诉他。Youmustn'ttellhimaboutit.你一定不要把这件事告诉他。—MustIbehomebeforeeighto’clock8点之前我必须回家吗？—Yes,youmust./No,youneedn‘t./No,youdon’thaveto.是的，必须回家。/不，不必。Completetheanswerswithmightandoneofthephrasesinthebox.watchTVontheweekendmycousinvisitmygrandparentspracticetheviolin3aA:WhatareyougoingtodoonSaturdayB:I’mnotsure.Imight______________________.2.A:WhatareyouplanningtodoafterschoolB:Idon’tknow.________________.3.A:WhenwillyoufinishthesciencehomeworkB:_________________________________________.visitmygrandparentsImightwatchTVIdon’tknow.Imightfinishitontheweekend将要；打算计划做某事将要4.A:WhoareyougoingtothemovieswithB:_______________________________________________.5.A:AreyoufreetocometomyplaceonSaturdayB:____________________________________________.I’mnotsure.ImightgowithmycousinI’mnotsure,Imighthavetopracticetheviolinbefreetodosth有空做某事

begoingto&willbegoingto表示即将发生的动作；

will表示将来发生的事情，不一定是最近期间之事。Shetoldhimshewasgoingtoquitthejob．她告诉他，她即将辞职。ShewillgotoAustralianextyear．她明年要去澳洲。Forreference2.begoingto:表示某人打算做某事，含有主观意愿；

will:用以叙述某件将要发生之事，是一种客观的叙述。Heisnotgoingtobemadeascapegoat．他不会去做替罪羊。Hewillnotbecomeascapegoat．他不会做替罪羊。3.在表示按计划或安排要发生的动作时，可以用begoingto；will只表示单纯的将来，并无按规定或计划之意。TherailwayisgoingtobeopenonOctober1．这条铁路将于十月一日通车。Thisrailwaywillbeelectrifiedwhenthereisaneed.如果需要，这条铁路将实现电气化。PairworkPracticethe5conversationsin3awithyourpartner.visitmygrandparents.ImightwatchTV.Idon’tknow.Imightfinishitontheweekend.I’mnotsure.Imightgowithmycousin.I’mnotsure,Imighthavetopracticetheviolin.3bCompletethesentencesbelow.Usethewordsinbracketstohelpyou.1.Inviting:_______________________________(can/playtennis)Accepting:_______________________________2.Inviting:__________________________________________(wouldliketo/gotothemovies)Refusing:_______________________________Reason:_________________________________(mighthaveto)CanyouplaytennisonSaturdaySure.Thatsoundsgreat.WouldyouliketogotothemoviesonFridaySorry,Ican’t.Imighthavetogooutwithmyparents.3.Inviting:_______________________________(can/hangoutwithustonight)Refusing:_______________________________Reason:____________________________(must)4.Inviting:_______________________________________________(wouldliketo/cometomybirthdayparty)Accepting:_______________________________CanyouhangoutwithustonightSorry,I’mnotfree.Imuststudyforatest.WouldyouliketocometomybirthdaypartySure.I’dloveto.Writedowneverythingyouhavetodonextweek.Chooseadayandtimetohaveaparty.Theninviteclassmatestoyourparty.
