Canyou...?意為“你能……嗎？”，可用于邀請別人或委婉地請求某人去做某事。其肯定回答常用

Sure,I’dlove/liketo.，否定回答常用

I’msorry,Ican’t./Sorry,Ican’t.等。如：---Canyougotothebaseballgame?你能去參加棒球比賽嗎？---I’msorry,Ican’t.

對不起，我不能。Explanation

單項填空---CanyouhelpmewithmyEnglishthisweekend?---Sorry,I______.Ihavealotofhomeworktodo.A.can’tB.mustn’tC.needn’tD.don’t答案：A

題意：“請問這個周末你能幫我學習英語嗎？”“對不起，我不能。我有很多作業(yè)要做”。不能答應他人的請求時常用“(I’m)Sorry,Ican’t.”。

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/他應該好好學習。

Hehastostudyhard.

他不得不好好學習。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。

試將下面三種話分別寫成（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。

—MustIbehomebeforeeighto’clock?

8點之前我必須回家嗎？

—Yes,youmust./No,youneedn't./No,youdon'thaveto.

是的，必須回家。/不，不必。
