情態(tài)動(dòng)詞haveto與其他的情態(tài)動(dòng)詞如can,may,must和should”

不同。

（1）這4個(gè)情態(tài)動(dòng)詞沒有人稱的變化,而haveto有。它的第三人稱單數(shù)為“hasto”。

You/

Heshouldstudyhard.你/他應(yīng)該好好學(xué)習(xí)。

Hehastostudyhard.

他不得不好好學(xué)習(xí)。haveto的用法（2）這4個(gè)情態(tài)動(dòng)詞在一般疑問句中將它們放在句首,在否定句中直接在他們后邊加not即可。我們以can為例:Canhegowithus他能和我們一起去嗎？Hecan’tgowithus.他不能和我們一起去。而haveto要加助動(dòng)詞do,does或did才可能完成其疑問、否定句。試將下面三句話分別寫成（1）一般疑問句，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與must

二者都有“必須”之意，但haveto

表示“客觀上的需要”，有人稱和時(shí)態(tài)的變化，否定形式為don’t/doesn’t/didn’thaveto(沒必要)；must表示“主觀上的要求”，無人稱和時(shí)態(tài)的變化，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.

冬天我們不得不穿上暖和的衣服。(客觀需要)ImustfinishmyhomeworkfirstbeforeIwatchTV.看電視前我必須先完成作業(yè)。(主觀要求)Youdon'thavetotellhimaboutit.你不一定要把此事告訴他。Youmustn'ttellhimaboutit.你一定不要把這件事告訴他。—MustIbehomebeforeeighto’clock8點(diǎn)之前我必須回家嗎？—Yes,youmust./No,youneedn‘t./No,youdon’thaveto.是的，必須回家。/不，不必。Completetheanswerswithmightandoneofthephrasesinthebox.watchTVontheweekendmycousinvisitmygrandparentspracticetheviolin3aA:WhatareyougoingtodoonSaturdayB:I’mnotsure.Imight______________________.2.A:WhatareyouplanningtodoafterschoolB:Idon’tknow.________________.3.A:WhenwillyoufinishthesciencehomeworkB:_________________________________________.visitmygrandparentsImightwatchTVIdon’tknow.Imightfinishitontheweekend將要；打算計(jì)劃做某事將要4.A:WhoareyougoingtothemovieswithB:_______________________________________________.5.A:AreyoufreetocometomyplaceonSaturdayB:____________________________________________.I’mnotsure.ImightgowithmycousinI’mnotsure,Imighthavetopracticetheviolinbefreetodosth有空做某事

will表示將來發(fā)生的事情，不一定是最近期間之事。Shetoldhimshewasgoingtoquitthejob．她告訴他，她即將辭職。ShewillgotoAustralianextyear．她明年要去澳洲。Forreference2.begoingto:表示某人打算做某事，含有主觀意愿；
