情態(tài)動詞haveto與其他的情態(tài)動詞如can,may,must和should

不同。

（1）這4個情態(tài)動詞沒有人稱的變化,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個情態(tài)動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.

Dotheyhavetogototheparty?Yes,theydo.Theydon’thavetogototheparty.b.Hehastogotoseethedoctor.

Doeshehavetogotoseethedoctor?Yes,hedoes.Hedoesn’thavetogotoseethedoctor.c.Shehadtostudyforamathtestyesterday.

Didshehavetostudyforamathyesterday?Yes,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。
