shallshallnotshan’toughttooughtnottooughtn’tshouldshouldshouldn’t

一、情態(tài)動詞can與could的用法1．表示能力：翻譯為會，能can用來表示現在的能力，could表示過去的能力Icanplaybasketballnow,butIcouldn’twhenIwasyoung.2.表示可能性:can多用于否定句和疑問句中，但也可用在肯定句中；could表示過去的可能，多用于間接引語中。1)Thatcan’tbeMary—shehasgonetoschool.2)ItoldthebossthatIcouldn’tfinishtheworkinsuchashorttime.3.表示請求或允許，譯為“可以”。表示此意時，用could語氣更委婉。-Can/CouldIborrowyourbike?-Yes,youcan.【拓展】1)表示驚訝、懷疑、不相信的態(tài)度(主要用于否定句、疑問句和感嘆句中)。

Canhardworkchangeapersonthatmuch?2)can亦可表示“有時會”。Youcanbeverynaughty.二、beableto的用法beableto意為“能夠，有能力”，不僅有時態(tài)、人稱和數的變化，而且還可以與某些情態(tài)動詞連用(通常不與can連用)，甚至還可以有非謂語形式。Sincehisaccidenthehasn'tbeenabletoleavethehouse.自出事之后，他一直未能離開家。Youmightbeabletopersuadehim.你也許能夠說服他。Ihopetobeabletodothework.我希望能干得了這項工作。Iregretnotbeingabletohelpher.我很遺憾未能幫助她?！疽谆毂嫖觯篶an,beableto表示“能力”時的區(qū)別】Babiescanswimwhentheywereborn.嬰兒們剛生下來時會游泳。(自身具有的能力)Withouthishardwork,hewasnotabletogetgoodgrades.如果他沒有努力工作，他是不可能取得好成績的。(經過努力)can 用于指現在，常表示自身具有的能力beableto用于各種時態(tài)，表示經過努力后所具有的能力三、情態(tài)動詞may與might的用法1.表示說話人的猜測，意為“或許；可能”，might表示的可能性比may小。

You’dbettertakeanumbrella.Itmay/mightrain.2.用來提出問題，問可不可以。用might時語氣更委婉。

Might/Mayweuseyourtypewriterforalittlewhile?3.表示“可以”。作此用法時，might是may的過去式。1)Youmaycomeifyouwish.2)Theboyaskedhismotherifhemightgotoplaybasketball.4．“may/mightaswell＋動詞原形”表示“不妨，還不如”Imay/mightaswellstartatonce.我還不如馬上就動身。四、will/would1.表示習慣性動作。will指現在，would指過去。1)Fishwilldiewithoutwater.2)Hewouldgetupearlywhenhelivedinthecountry.2.表示請求、建議等。用would比用will委婉、客氣。Will/Wouldyoupleasepassmethatbook?【拓展】表示意愿或意志。will表現在，would表過去。1)Iwillhelpyouifyouneedme.2)Hesaidhewouldhelpyouifyouneededhim.五、shall/should◆shall1.用于第一人稱疑問句中，表示征求對方的意見或向對方請示。

Thisroomissodirty.Shallwecleanit?2.用于第二、三人稱，表示法律等條文中的規(guī)定或說話人的決心、給對方的命令、警告、允諾或威脅。Nothingshallstopusfromcarryingouttheplan.◆should1.用于第一人稱疑問句詢問對方的意愿，但語氣更委婉溫和。ShouldIopenthewindow?2.表示勸告、建議、命令、責任或義務。Nomatterwhoyouare,youshouldobservethelaw.3.表示推測或可能性。Youshouldbehungryafterthelongwalk.【拓展】should還可表示意外、驚訝等，意為“竟會，竟然會”。Itissurprisingthatheshouldhavemadesuchafoolishmistake.六、must/can’t1.must表示義務、必要性、命令，意為“必須”。否定式mustn’t表示“不準；禁止”。

Wemustdoeverythingstepbystep.2.must表示推測，意為“想必；準是；一定”，只用于肯定句，否定句用can’t。1)Aftersuchalongwalk,youmustbetired.2)--Myhouseisnearabusystreet.--Itcan’tbeveryquiet.【拓展】表示與說話人愿望相反、不耐煩的感情色彩，可譯為“一定要；偏偏；非得”。

Ifyoumustknow,hernameisMary.3．回答must問句時，肯定回答多用must;否定回答多用needn't或don'thaveto?！狹ustIfinishmyhomeworkbeforeeighto'clock?—Yes,youmust.(No,youneedn't/youdon'thaveto.)——我必須要在8點之前完成作業(yè)嗎？——是的，必須。(不，沒必要。)七、haveto的用法haveto表示“不得不，必須”，有人稱、時態(tài)和數的變化。否定式為don’thaveto。1)Therearesomanymistakesinhisarticlethathehastorewriteit.2)Youdon’thavetobuyagift,butyoucanifyouwantto.【比較】must和haveto表示“不得不、必須”時，haveto與must意思上很接近。但must常表示說話人的主觀看法；而haveto一般強調客觀需要。1)I’mverytired.Imustsitdownandhavearest.2)Ihavetohurryupnow.Ihaveatraintocatch.八、oughtto的用法oughtto表示“應該；應當”，可以表示有責任或義務而做某事。沒有人稱、數和時態(tài)的變化，否定式為oughtnotto1)Theyoughttoapologize.2)Suchthingsoughtnottobeallowed.3)Heoughtn'ttohavebeendrivingsofast.【比較】oughtto和shouldoughtto與should一般來說，兩者可以互換，只是oughtto的語氣略強。另外，表示出于法令規(guī)則、行為準則、道德責任等客觀情況而“應該”做某事，通常用oughtto；若用should則含有個人意見，強調主觀看法。1)Youareolderbrother.Yououghttotakecareofyourlittlesister.2)YoushouldnotwastetimeinwatchingTV.九、hadbetter的用法hadbetter，“最好”，縮寫為“’d?better”，表示提出建議、勸告或命令等，含有“應該做某事，有義務做某事”之意，翻譯為最好，一般適用于對晚輩、平輩。1)It'shalfpasttwo.Ithinkwehadbettergohome.否定形式為hadbetternot，疑問句中hadbetter的否定形式有兩種：Hadn’t?+主語?+better?+?V原形+...?Had?+?主語?+?better?not?+V原形+…?1)Youhadbetternottalkwithstrangers.2)Hadn’tyoubettergowiththem??十、dare的用法

dare既可作情態(tài)動詞，也可作實義動詞。1．dare作情態(tài)動詞時，表示“敢，敢于”，后跟動詞原形，常用于疑問句、否定句和條件句中。此時的dare沒有人稱、數和時態(tài)的變化，能單獨構成否定和疑問。例如：Dareyouclimbthattree?Hedaren'tgotherebecauseitisverydangerous.2．dare用作實義動詞時，有時態(tài)和人稱的變化，用do,does或did來構成否定句或疑問句。Shedidn'tdaretosayaword,didshe?十一、need的用法1．作情態(tài)動詞(1)need作情態(tài)動詞時，常用于疑問句、否定句或條件句中，意為“必須”或“需要”?！狽eedIfinishtheworktoday?—Yes,youmust./No,youneedn't.(2)needn't意為“不必”，表示客觀上不必如何。There’splentyoftime.Youneedn’t.2．作實義動詞need作實義動詞時，后可接名詞、動名詞、不定式等，有人稱、時態(tài)和數的變化。Thebikeneedsrepairing.＝Thebikeneedstoberepaired.這輛自行車需要修理。情態(tài)動詞的特殊用法情態(tài)動詞表推測：情態(tài)動詞+do推測現在或將來發(fā)生的動作或狀態(tài)；情態(tài)動詞+bedoing推測正在進行的動作或狀態(tài)；情態(tài)動詞+havedone推測過去發(fā)生的動作或狀態(tài)。1)Timmusthaveacarnow.2)Hemustbedoinghisexercisesintheclassroom.3)Hemusthavefinishedthework,forheischattingwithhisclassmateshappily.1.對肯定、把握性很大情況的推測：mustbe/do(現在或將來)mustbedoing(說話時正在進行)musthavedone(已發(fā)生的或狀態(tài))2.對否定情況的推測：can/couldnotbe/do(現在或將來)can/couldnotbedoing(正在發(fā)生的動作)can/couldnothavedone(過去的動作或狀態(tài))3.對不太肯定、把握性不大情況的推測：may/might(not)be/do(現在或將來)may/might(not)bedoing(說話時正在發(fā)生動作)may/might(not)havedone(已發(fā)生的動作或狀態(tài))情態(tài)動詞的特殊用法情態(tài)動詞表推測：情態(tài)動詞+havedone(1)could/mighthavedone本來能夠做的事卻沒做Hecouldhaveworkedouttheproblem.(2)should/oughttohavedone本來應該做而實際上未做
