情態(tài)動(dòng)詞(Modals)本身具有一定的詞義,不能獨(dú)立作謂語(yǔ),必須和動(dòng)詞原形一起構(gòu)成謂語(yǔ)。情態(tài)動(dòng)詞雖然數(shù)量不多,但用途廣泛。常用的情態(tài)動(dòng)詞包括can(could),may(might),will(would),shall(should),must,need,dare,hadbetter,oughtto,usedto等?!綽eableto的用法】1.beableto后跟動(dòng)詞原形,表示具體的能力,與can的用法相近。Eg:LittleTedisnotabletoanswertheteacher’squestion.2.beableto表示“能力”時(shí),和can的用法相似。但也有區(qū)別:(1)beableto有多種時(shí)態(tài),如:was/wereableto,will/shallbeableto,have/hasbeenableto等,而can只有兩種時(shí)態(tài),即can和could。(2)beableto強(qiáng)調(diào)通過(guò)努力而獲得的能力,而can則強(qiáng)調(diào)自身已具有的能力。Eg:ShecansingthesonginEnglish.Eg:HewillbeabletosingthissonginEnglishinafewminutes,too.(3)beableto強(qiáng)調(diào)一種結(jié)果,而can只強(qiáng)調(diào)一種可能。
Eg:Luckily,hewasabletoescapefromthebigfireintheend.
Eg:Ifhegothereafewhoursearlier,Icouldsavehim.(4)beableto的否定形式是在be后面直接加not,即benotableto。
Eg:Thekidisnotabletowrite.Eg:But

thisfor

scenario.
【haveto的用法】1.haveto意為“不得不,必須”。后跟動(dòng)詞原形。Eg:Ihavetobeoffnow.Thetrainisleavinginanhour.2.haveto與must的區(qū)別:(1)must強(qiáng)調(diào)說(shuō)話者的主觀意愿;
haveto強(qiáng)調(diào)客觀上的必要性。
Eg:Thelastbusleft,andJohnhadtowalkhome.
Eg:Imustfinishthepaperbynoon.(2)mustn’t不許,不可以,表示禁止;nothaveto不必。
Eg:Youmustn’tbelatefortheexam.
Eg:Anndoesn’thavetocookforherself.Sheworksatahotelandgetsallhermealsthere.hadbetter后跟動(dòng)詞原形,表示“最好……”,其否定形式是在hadbetter后加not,疑問(wèn)式是把had和not提前。Eg:Youhadbetternottalkwithstrangers.Eg:Onehadbetterseelifeinitsvariousaspectswhenyoung.Eg:Hadn’tthedoctorbetterseehim醫(yī)生是不是去看看他比較好?【hadbetter的用法】【dare的用法】1.dare作情態(tài)動(dòng)詞時(shí),主要用于否定句、疑問(wèn)句和條件從句中,一般不用在肯定句中。Eg:HowdareyousayI’munfair2.情態(tài)動(dòng)詞dare可以有過(guò)去式dared,但也可以直接用dare表示過(guò)去式,或后接動(dòng)詞完成式。Eg:Motherdare(d)nottellfathershe'dgivenawayhisoldjacket.3.dare用作實(shí)義動(dòng)詞,有時(shí)態(tài)、人稱和數(shù)的變化。所不同的是,作實(shí)義動(dòng)詞時(shí),在肯定句中dare后面通常接帶to的不定式;在否定句和疑問(wèn)句中,dare后可接帶to或不帶to的不定式。Eg:Iwonderhowhedares(to)saysuchthings.Eg:Hedoesnotdare(to)answer.【need的用法】1.need表示“需要”或“必須”,作情態(tài)動(dòng)詞時(shí),用于否定句和疑問(wèn)句中,在肯定句中一般用must,haveto,oughtto或should代替。Eg:Youneedn’tcomesoearly.2.need作為行為動(dòng)詞,可用于肯定句、否定句和疑問(wèn)句中,其后可接名詞、代詞、動(dòng)名詞或帶to的動(dòng)詞不定式為其賓語(yǔ)。Eg:Youneedtopracticereadingaloudeveryday.
注意對(duì)need問(wèn)句的回答:—NeedIfinishtheworktoday—Yes,youmust./No,youneedn’t./No,youdon’thaveto.needn’t對(duì)其它情態(tài)動(dòng)詞的回答:—ShallItellJohnaboutit—No,youneedn’t/don’thaveto.—Mustwedoitnow—No,youneedn’t/don’thaveto.3.CompletethetipsforgoodtablemannerswiththecorrectformofthemodalsinActivity1.WhilegoingonyourfirsttriptotheUKisexciting,newanddifferentcustomscanalsobeconfusing.Tablemannersarenoexception.Butdon’tworry—herearesometips:?You1._________waituntileveryoneelsehasbeenservedbeforeyoustarteating.?Sometimestherearesomanyknivesandforksthatyou2.__________pickthemupincaseyougetitwrong.Thetrickistostartwiththeonesontheoutside.?Whenyoufinishyourmeal,you3.____________placetheknifeandforktogetheronyourplatewiththehandlesatthefouro’clockposition.Tablemanners,however,candifferindifferentsituations.Forexample,you4.______________________useaknifeandforkwheneatingahamburgerorpizza.Justremember:wheninRome,doastheRomansdo,andyouwill5.__________enjoythelocalcuisine!havetodarenothadbetterneedn’t
