could,

may,might,

must,

oughtto,

shall,should,

will和would。另外，dare,

need,

haveto和usedto也具有情態(tài)動詞的某些特性。2)can與could表示能力（ability），意思相當(dāng)于beableto。如：Jackcanswim.Myfathercouldstandonhishandswhenhewasyoung.注意：在一般過去時中，was/wereableto通常表示能做并且已經(jīng)做了的事，could僅表示能力。如：Iwasabletoswimtothebankwhentheshipsank.Icouldlifttheheavybox.3)must與need表示必要性（necessity）。must意為“必須”，否定式mustn’t意為“不許”；need意為“需要”，否定式needn’t意為“不必”。如：Imustgonow.Youmustn’tforgetyourticket.Needwegorightnow?Youneedn’tdoitifyoudon’twantto.注意：haveto也有“必須”的含義，但側(cè)重客觀需求，有時態(tài)的變化，否定式是don’t/doesn’thaveto，意為“不必”，意思相當(dāng)于needn’t。如：Wewillhavetothinkofanewplan.Youdon’thavetorun.4)can,could,

may與might表示許可（permission）。表示許可時，may多用于正式場合，could和might的語氣更委婉些。如：Youcanusemypenifyoulike.Studentsmaynotbringtheirpetstoschool.Could/MightIborrowyourbike?5)can,

could,

may,

might與must表示可能性（possibility）。may,

might和could常用于肯定句，意為“可能”，must用于肯定句，意為“一定”；否定式may/mightnot意為“可能不”，can’t/couldn’t意為“不可能，肯定不”。如：Thatmay/might/couldbeagoodidea.Youmustbetiredafterthelongjourney.Theremaynotbeenoughmoneytopayforanewcar.Yourstorycan’t/couldn’tbetrue.注意：can表示可能性時，含“有時會”的意思。如：Thetemperatureherecanbeashighas37°C.6)should與oughtto表示義務(wù)（obligation）或建議（suggestion），意為“應(yīng)該”。如：Theyshould/oughttobuildmorelibraries.注意：should與oughtto也可以表示主觀判斷，意思是“可能會，應(yīng)該會”，相當(dāng)于willprobably。如：Therainshould/oughttostopsoon.7)will與wouldA.表示習(xí)慣性動作（habit）。will表示現(xiàn)在的習(xí)慣，would表示過去的習(xí)慣。如：Marywilllistentomusicforhoursinherroom.IwouldtakeawalkaftersupperwhenIwasyoung.B.表示意愿（willingness）。如：Thebabywon’tgotosleep.C.表示請求（request），would比will更委婉些。如：Wouldyougivemesomeadvice?注意：usedto也表示過去的習(xí)慣性動作，多用于非正式場合，往往指后來停止了的動作。否定形式是didn’tuseto或usednotto。如：Iusedtohaveabicycle,butIsoldit.Johndidn’tusetocomehere.DidMikeusetoreadnewspapers?8)shallA.在疑問句中，表示建議或征求意見。如：ShallIhelpyouwiththebox?B.表示承諾或要求。如：Youshallhavethemagazine.HeshalldoasItellhim.C.用于正式文件、法律、規(guī)章制度等，表示規(guī)定。如：Studentsshallnotusecalculatorsduringexams.9)dare與needdare和need作為情態(tài)動詞，常用于疑問句和否定句中。這兩個詞也可以用作實義動詞。如：Idarenotgotherealone.Ididn’tdaretosayaword.Nobodydaredtoaskanyquestions.Needwefinishtheworktoday?Youneedn’tworryaboutit.Youdon’tneedtocomeyourself.10)情態(tài)動詞的進行式、完成式和被動式A.情態(tài)動詞可以與主動詞的進行式合用，表示某動作正在進行。如：Jackmaybereadinginthelibrary.B.情態(tài)動詞可以與主動詞的完成式合用，表示過去發(fā)生的動作。如：Tommusthavearrivedhomebynow.Youcan’thaveseenHenryyesterdaybecausehewasinLondon.C.情態(tài)動詞可以與主動詞的被動式合用。如：Theroadmaybeblocked.6.Readthefollowingdialogueandcompletethetablebelowit.A:MayIaskyouaquestion?B:Yes,please.A:Ifindithardtodecidewhattoread.Wouldyougivemesomeadvice?
