Canyou...?意为“你能……吗？”，可用于邀请别人或委婉地请求某人去做某事。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?你能去参加棒球比赛吗？---I’msorry,Ican’t.

对不起，我不能。Explanation

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

题意：“请问这个周末你能帮我学习英语吗？”“对不起，我不能。我有很多作业要做”。不能答应他人的请求时常用“(I’m)Sorry,Ican’t.”。

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。

试将下面三种话分别写成（1）一般疑问句，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’clock?

8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。
