情態(tài)動詞（Modals）本身具有一定的詞義，不能獨立作謂語，必須和動詞原形一起構成謂語。情態(tài)動詞雖然數量不多，但用途廣泛。常用的情態(tài)動詞包括can(could),may(might),will(would),shall(should),must,need,dare,hadbetter,oughtto,usedto等。【beableto的用法】1.beableto后跟動詞原形，表示具體的能力，與can的用法相近。Eg:LittleTedisnotabletoanswertheteacher’squestion.2.beableto表示“能力”時，和can的用法相似。但也有區(qū)別：(1)beableto有多種時態(tài)，如:was/wereableto,will/shallbeableto,have/hasbeenableto等,而can只有兩種時態(tài)，即can和could。(2)beableto強調通過努力而獲得的能力，而can則強調自身已具有的能力。Eg:ShecansingthesonginEnglish.Eg:HewillbeabletosingthissonginEnglishinafewminutes,too.(3)beableto強調一種結果，而can只強調一種可能。

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

【haveto的用法】1.haveto意為“不得不，必須”。后跟動詞原形。Eg:Ihavetobeoffnow.Thetrainisleavinginanhour.2.haveto與must的區(qū)別：(1)must強調說話者的主觀意愿；

haveto強調客觀上的必要性。

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后跟動詞原形，表示“最好……”，其否定形式是在hadbetter后加not，疑問式是把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)動詞時，主要用于否定句、疑問句和條件從句中，一般不用在肯定句中。Eg:HowdareyousayI’munfair2.情態(tài)動詞dare可以有過去式dared，但也可以直接用dare表示過去式，或后接動詞完成式。Eg:Motherdare(d)nottellfathershe'dgivenawayhisoldjacket.3.dare用作實義動詞，有時態(tài)、人稱和數的變化。所不同的是，作實義動詞時，在肯定句中dare后面通常接帶to的不定式；在否定句和疑問句中，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)動詞時，用于否定句和疑問句中，在肯定句中一般用must,haveto,oughtto或should代替。Eg:Youneedn’tcomesoearly.2.need作為行為動詞，可用于肯定句、否定句和疑問句中，其后可接名詞、代詞、動名詞或帶to的動詞不定式為其賓語。Eg:Youneedtopracticereadingaloudeveryday.

注意對need問句的回答:—NeedIfinishtheworktoday—Yes,youmust./No,youneedn’t./No,youdon’thaveto.needn’t對其它情態(tài)動詞的回答:—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
