情态动词主要有：may/might,can/could,must,haveto,shall/should,will/would,oughtto,need,dare,usedto现在我们来着重学习情态动词can以及haveto的用法。其特征主要有：
情态动词can的基本用法情态动词can有一定的词义，但不能独立存在，它必须与动词原形一起构成谓语。情态动词can没有人称和数的变化。其具体用法如下:表示“能、会”指脑力或体力方面的“能力”。如:►IcanspeakJapanese.我会讲日语。►FrankcanswimbutIcan’t.佛兰克会游泳,但我不会。
2.表示“可能”，常用于否定句或疑问句中，指某种可能性。例如：►Mycousincan’tbeinthiscity.HeisinKoreanow.我堂兄不可能在这个城市里。他在韩国呢。►Canhecometoourclubtoday,please?请问他今天能来我们俱乐部吗？3.表示“可以”，常用于口语中，指许可或请求做某事►CanIaskyouaquestion?我可以问你一个问题吗？►Youcanbringsomethingtoeat.你可以带些吃的。
can为情态动词,在本单元中表示请求，用于发出邀请，后跟动词原形。当同意接受对方的邀请时，常用Sure,I’dloveto./Certainly./Ofcourse.等来回答；若不接受，常用Sorry等来有礼貌地拒绝，一般情况下需要说明不能接受邀请的原因以表示歉意。►—Canyoucometomybirthdaypartytomorrow？明天你来参加我的生日聚会，好吗？—Sorry,Ican’t.Iamgoingtovisitmygrandpa.很抱歉，我来不了，我要去看我爷爷。
can/may(1)都可表示“许可”。may用于较正式场合，can比较口语化。Youmay/cansmokehere.►Borrowersmaynottakeoutofthelibrarymorethantwobooksatatime.►Thepolicemansaysyoucan’tparkhere.(2)May/CanI/we…?表示征询对方许可。Canyou…?表请求。①—MayIuseyourphone?—Yes,youmay./Yes,please./No,youmaynot./No,youmustn’t./No,you’dbetternot./I’mafraidnot.
/I’msorry.I’dratheryoudidn’t.②—CanIgooutandplay,Mum?—Yes/Certainly,youcan./No,youcan’t.③—Canyouhelpmewiththisbag?—Withpleasure./Sorry,Ican’t.(3)都可表示“可能性”Mr.Reedlookspale.Hemaybeill.Mr.Readisinpoorhealth.Hecanbeillatanytime.Thisnewsmaybetrue.(=might/could)WangWeicanbereallystubborn.
Mr.Reedlookspale.Hemaybeill.Mr.Readisinpoorhealth.Hecanbeillatanytime.Thisnewsmaybetrue.(=might/could)WangWeicanbereallystubborn.(4)can还可表示“能力”、“能够”—Youcanswim,can’tyou?—No,Ican’t.Ican’tpromiseanything,butI’lldowhatIcan.TicketscanbeboughtfromtheTouristInformationCenter.
haveto的用法1.have(has)to+动词原形have(has)to后面要用动词原形。当主语为第三人称单数时用hasto，当句子是过去时用hadto。►Wehavetogohomenow.我们不得不现在就回家。►HehastoworkonSunday.他不得不在周日工作。►IhadtodomuchhouseworklastSunday.上周日我不得不做很多作业。
2.haveto的否定句句型：主语+don’t/didn’t/doesn’twon’t+haveto+动词原形►Youdon’thavetowalksofast.你不必走那么快。►Hewillnothavetobuyanewcoatnextyear.明年他没必要买新外衣了。3.haveto的疑问句句型：Do/Does/Did/Will+主语+haveto+动词原形
Didhehavetoaskthequestion?他非要问那个问题吗？Yes,hedid.是的。No,hedidn’t(haveto).不。不能独立作谓语，只能和动词原形一起构成谓语，表示说话人的语气和情态。2.没有人称和数的变化。(haveto除外)3.否定形式：在其之后加not(haveto除外)疑问形式：情态动词提到主语之前(haveto除外)。
3.haveto的意思是“必须、不得不”,往往强调由于客观原因而必须做某事。haveto后接动词原形；haveto有人称、数和时态的变化,其第三人称单数形式为hasto,其疑问形式和否定形式要借助于助动词do或does来完成。例如：►Wehavetolookafteroursisterathome.我们不得不在家照顾我们的妹妹。►Doeshehavetogetupearlytomorrowmorning?明天早上他必须早起吗？►Idon’thavetostayathometoday.今天我不必待在家里。
4.must/havetomust表示主观“必须”；haveto表示客观客观需要，即“不得不”。Idon’tlikethisTVset.Imustbuyanewone.ThisTVsetdoesn’twork.Wehavetobuyanewone.Youmustgetupatfivetomorrow.We(will)havetogetupearlytomorrow.IhadtoleaveearlybecauseIwasn’tfeelingwell.Shesaidshemust/hadtoseethemanager.
