whichdisappointedthemverymuch.第三节从句从句分为定语从句,状语从句和名词从句三大类。定语从句又分为限定性和非限定性从句两种,由关系代词或关系副词引导,修饰主句的某个成分。状语从句分为时间、结果、让步、原因、条件及行为方式状语从句。名词从句包括主语、宾语、表语和同位语从句及therebe句型。1.定语从句限定性定语从句中that可代表人和事,而which只代表事;二者在从句中作主语或宾语。that作宾语时常可省略,which则不能,而且其后的“不及物动词+介词’’中的介词不能省略。which作宾语时,先行词与which之间的介词不能省。例如:Thefirstdollthatcouldsay“mama”wasinventedin1830.Thesecondhalfofhisvoyagewasbyfarthemoredangerouspart,duringwhichhesailedroundtheCapeHorn.代表a11,anything,something,nothing,much等词时,用that而不用which,that作宾语可省略。例如:Icareanythingthathassomethingtodowithit.You'dbetterdosomethinghepreferstodotopleasehim.Thatisthelasttimewemeteachother.Icameacrossthewomanyoutoldmeaboutyesterday.who和whom引导的从句用来修饰人,分别作从句的主语和宾语。where是关系副词,用于表示地点的定语从句,而when用来表示时间。whose是关系代词,修饰名词作定语。例如:HenryFordisthepersonwhoismostresponsiblefordevelopingtheideaofmassproduction.Thekneeisthejointwherethethighbonemeetsthelargeboneofthelowerleg.Thenextmorning,whenshecamedowntobreakfast,Marywasbeamingwiththepleasureofanew,greatdiscovery.Thevisitingprofessorisafamousscientistwhosesonstudiesinmydepartment.在下列情况,限定性定语从句的关系代词可以省略:1)当关系代词在从句中作宾语或表语;或它们在从句中作介词的宾语,而该介词又在句末时;2)当先行词是that,all,only,everything,something,nothing等代词时,或先行词前有一个最高级形容词修饰时;3)当先行词前有only,any,all,first,no,last等修饰时,或先行词就是time,moment,way(anyway),direction,distance等名词时,关系代词即可省略。例如:Thedelegationwehadbeenwaitingforfinallyarrived.Imetthewomanyoutoldmeabout.Shegavemeallshecouldafford.WithTVwecanseethingshappenalmostattheexactmomenttheyarehappening.非限定性定语从句,其作用为:对所修饰的成分作进一步的说明,它与主句用逗号隔开。此类从句省略后其余部分仍可成立。在非限定性定语从句中,which可代表前面的整个句子;代表人时只能用who,whom,而不能用that;as也可用作关系代词。例如:Thetelephone,asweknow,wastheinventionofAlexanderGrahamBell.TheLittleWhiteHouseinWarmSpringswastheGeorgiahomePresidentFranklinD.Roosevelt,whodiedthereonApril12,1945.Livinginadamphouseforalongtimeisharmfultoone’shealth,whichisknowntoeveryone.2.状语从句状语从句可分为:时间状语从句(主要由when,whenever,after,before,a5,slnce,once,assoonas,Until,while等连词引导),结果状语从句(由so…that和such…that连接),让步状语从句(由though,although,nomatter,evenif,however,whatever等词引导),原因状语从句(由as,because,since和for引导),条件状语从句(由if,whether,aslongas,providedthat等词引导),地点状语从句(由where引导),行为方式状语从句(由as引导)。有时条件状语从句中,主句不可以用将来时,而用一般时代替。例如:\nThesmallgreenishflowersoftheelmtreeappearintheSpring,longbeforetheleavesgrow.QiongYao'snovelsusedtobesopopularthatherbooksappearedonbest-sellerlists.Gasballoonislesssafethanhotballoonbecauseitmaycatchfire.Uniformacceleration(同样的加速)occursiftherateofchangeremainsthesameoversuccessiveequalintervalsoftime.ThousandsofChinesecollegestudentswenttotheUSConsulateShanghai,wheretheyprotestedNATO'sbombingatChina'sEmbassyinYugoslavia.状语从句中的“主语+be”可以省略,前提是:从句主语和主句主语一致,且从句谓语“be”省略后的结构为“连词+现在分词/过去分词介词短语/形容词/名词短语”。)例如:Whenwellfitted,glassescancorrectmostsightdefectsinhealthyeyes.Ifnecessary,Iwouldliketoseeyouinyouroffice.Althoughseriouslywounded,henevercomplained.3.名词从句名词从句包括主语从句、宾语从句,其中有介词与形容词的宾语从句、表语从句和同位语从句。主语从句主语从句常出现在itis+名词、形容词、分词+主语从句”的形式中。例如:ItisreportedthatTaiwanesepopsingerMengTingweiwillholdasoloconcertinShanghaisomedaythismonth.Itmustbepointedoutthatyouhavefailedtomeetthedeadline.ItusuallyhappenedthatIwaslatebecauseoftrafficjams.主语从句还可用when,where,how,why,whether等连接副词,和who,whom,whose,what,which,whoever,whatever,whichever等连接代词来引起。例如:Howtoarrangethemeetingisnotyourtask.Whosecandidatewillwintheelectionisthequestionbothpoliticalpartiesareasking.WhenIleaveismyowndecision.Whoeverwillgotothepartywon'tchangemymindofstayingathome.2)宾语从句宾语从句可由that,疑问代词或副词how,why和where等引出。例如:Topostponetheconferenceuntilnextmonthindicatedthattheywereunprepared.Nearlya11thestaffagreedwithwhatIsaid.Everyoneworriedaboutherbecausenoonewasawareofwhereshehadgone.Couldyouoffermoredetailsexceptthatithappenedatnight?由what,whether,how引导的宾语从句可用在介词后,而由that引导的从句只跟but,besides,except,in,save之后。例如:Icanhardlybelieveinwhattheyhavedone.Hedoesn’tknowmyphonenumberexceptthatthecitycodeis021.一些表语性的形容词,如:alarmed,amazed,annoyed,astonished,certain,confident,disappointed,glad,pleased,proud,sad,shocked,sure,surprised,worried,ect.做表语时,后面可跟由that,how等引导的宾语从句。例如:Iwasamazedhowhecouldpasstheexamwithoutattendingthelectures.HeisconfidentthathewillpasstheBand6examination.Shewassurprisedhowsimplehisproblemis.Weareallpleasedthathewillbeabletopassthefinalexamination.3)表语从句表语从句对主语的内容起解释和阐述的作用;若表语从句用that引起,that起连接作用,不能省略。b表语从句也可用连接词how,when,where,why,what引起。由because引起的表语从句通常只用在“this/that/itisbecause”结构中。例如:Alogarithm(对数)iswhatisknowninalgebraexponent(代数的指数).OnethingIadmiremostaboutthemisthattheyarehospitable.\nSheworkstoohard;Thatiswhysheisexhausted.Imustpointoutthatwhereyouintendtobuildasuper-marketiswheretheelderlydoexerciseeveryday.4)同位语从句同位语从句是由两个或两个以上同一层次语言单位组成的结构,其中前项与后项所指相同,句法功能相同。同位语从句由that引导,也可由whether,how,why,where,when等来引导。例如:Sheignoredtheteacher'sinstructionthatshemuststudyhard.ThequestionwhetherornotIshouldhelphiminsuchacasetroubledmegreatly.第四节动词不定式1.不定式的基本形式与结构动词不定式指通常由to加上动词原形(如towrite)所构成的一种非限定性动词形式,但在有些情况下to可以省略。动词不定式有进行体和完成体(如上tobewriting,tohavewritten),也有被动态(如tobewritten),所有的主动词,不论是及物动词还是不及物动词,也不论是动作动词还是状态动词,都有不定式形式。助动词除be和have外,没有不定式形式。动词不定式在语法功能上可作主语、宾语、表语、定语和状语。2.不定式的用法1)不定式结构作主语TegetcontactwithhisfamilyinTaiwanmadehimextremelyhappysincetheyseparatedmorethan40yearsago.Tofinishthattaskinsuchashorttimeisreallyachallenge.在上述情况下,如果不定式较长,显得头重脚轻,则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替),而将不定式放到后面。如:ItmadehimextremelyhappytogetcontactwithhisfamilyinTaiwansincetheyseparatedmorethan40yearsago.Johnadmittedthatitisalwaysdifficultforhimtobeontime.不定式结构所表示的动作是谁做的,即不定式的逻辑主语,通常可以通过forsb.todosth.结构表达:Itisquiteimportantforustoreadgoodbooksduringageneralreview.Itisnotdifficultfotthosetalentedstudentstopasstheexam.在某些形容词(如careless,clever,considerate,foolish,good,impolite,kind,naughty,nice,silly,stupid等)作表语时,不定式后可以加of来引导出其逻辑主语:Itisverykindofyoutotellmethetruth.Itisstupidofhimtodosuchasillything.2)不定式作宾语不定式作宾语有两种:一种是及物动词后直接跟带to的不定式,另一种是“及物动词+疑问词+带to的不定式。及物动词+带to的不定式结构:只能跟动词不定式的动词,常见的有:afford,agree,aim,appear,ask,believe,care,claim,decidedemand,desire,determine,expect,fail,happen,hesitate,hope,intend,learn,long,manage,offer,pretend,promise,prepare,refuse,seek,swear,undertake,want,wish等。Hemanagedtosolvethecomplicatedproblem.Thestrangerofferedtoshowmetheway.Mr.SmithundertooktobuildanewplantinSouthAfrica.动词+疑问代(副)词+不定式:这类动词常见的有advise,decide,findout,forget,inquire,know,learn,see,regard,remember,teach,tell,understand,wonder等。常见的疑问代(副)词有:what,when,where,which,how,whether等。Hedoesnotknowwhentostart.Youcandecidewhethertocontinueortostop.Iwillshowyouhowtodealwithit.有时,不定式可由it代替,而把不定式放到后面去。这可以用这一结构表达:动词(如find,think,consider,feel等)+it+形容词+不定式。\nSheconsidersitnecessarytomakefriendswithhim.Wefinditdifficulttofinishallthehomeworkbefore9o’clock.3)不定式做表语一种情况为主语是不定式(表示条件);表语也是不定式(表示结果):Toseeistobelieve.Toworkmeanstoearnaliving.另一种情况为主语是以aim,duty,hope,idea,job,plan,problem,purpose,thing,wish等名词为中心的短语,或以what引导的名词性从句,不定式表语对主语起补充说明作用:Hisaimistostudyabroadinthenearfuture.Themostimportantthingistonegotiatewiththemabouttheprice.WhatIwanttosayistoforgetalltheunhappyexperience.4)不定式作定语不定式结构作名词词组修饰语主要有三种类型:第一种,被修饰的名词词组是不定式的逻辑宾语。例如:Therewasreallynothingtofear.Hegavemeaninterestingbooktoread.如果不定式是不及物动词,后面就得加相应的介词。例如:Maryneedsafriendtoplaywith.Thatgirlhasnothingtoworryabout.Theyhaveastrictteachertolistento.Althoughthefilmhadbeenonfortenminutes,Istillwasnotabletofindachairtositon.第二种,被修饰的名词词组是不定式的逻辑主语;例如:Haveyougotakeytounlockthedoor?Theactiontobetakeniscorrect.Thereisnothingtobegainedbypretending.第三种,被修饰的名词词组是不定式的同位结构。这类名词通常是表示企图、努力、倾向、目的、愿望、is算、能力、意向等意义的名词:ability,attempt,effort,impulse,inclination,wish等。例如:Herdaughterwillmakeanevenbiggerefforttopleaseher.Ihavenowishtoquarrelwithyou.NeitherofthemhadanyinclinationtodobusinesswithMary.5)不定式作状语不定式结构在句中作状语通常都能转换为限制性状语从句。例如作原因状语:Theyarequitesurprisedtoseethegreatchangestakingplaceinthearea.Theyarequitesurprisedbecausetheyseethegreatchangestakingplaceinthearea.Hewasluckytoarrivebeforedark.Hewasluckybecausehearrivedbeforedark.作目的状语:Sheraisedhervoicetobehearedbetter.Sheraisedhervoicesothatshecouldheardbetter.WewentviaHeidelbergtomissthetrafficjam.WewentviaHeidelbergsothatwecouldmissthetrafficjam.作结果状语:TheFrenchfootballteamplayedsosuccessfullyastodefeattheBrazilians.TheFrenchfootballteamplayedsosuccessfullythattheyevendefeatedtheBrazilians.Hegottothestationonlytobetoldthetrainhadgone.Hegottothestationandwastoldthatthetrainhadgone.不带to的不定式的使用\n动词不定式通常带to,但在有些搭配中不带to,在另一些搭配中可带to可不带to。归纳起来,以下情况下使用不带to不定式:1)在can/could,/may/might,will/would,shall/should,must,need,dare等情态动词之后,动词不定式不带to。2)在表示感觉意义的动词,如see,feel,watch,notice,smell,hear,observe等后,或是表示“致使”意义的动词,如have,let,make等后,动词不定式不带to。例如:Ioftenheardhimsaythathewouldstudyhard.Imusthavehimseehisownmistakes.但是,当这类结构转换为被动语态时,后面的不带to不定式一般转换为带to不定式。例如:Hewasoftenheardtosaythathewouldstudyhard.Afterhehadfinishedspeaking,hewasmadetoanswerinnumerablequestions.3)在动词help之后可用不带to的不定式,也可用带to的不定式。例如:Helptheoldlady(to)carrytheheavybox.4)在hadbetter,wouldrather,may/mightaswell,ratherthan,cannotbut等搭配之后,动词不定式也不带to。例如:Unlessyoufeeltoilltogoout,Iwouldrathernotstayathometonight.Shecouldnotbutcriticizehisfoolishbehaviour.5)在makedo,makebelieve,letdrop,1etfall,1etfly,letslip,letdrive,letgooff,hearsay,heartell,leavegoof等固定搭配中,用不带to的动词不定式。例如:Theyletgooftherope.他们松开了绳子。Johnletflyatorrentofabuseatme.约翰朝我痛骂了一顿。I'veheardtellofhim.我听说过他。Someofthefacultywereletgoforlackofthestudents.由于生源不足,一些教职员工被解雇了。6)在介词but,except之后,如果其前有动词do的某种形式,其后不定式一般不带to,反之则必须带to,表示“不得不,只能”。例如:Hewilldoanythingexceptworkonthefarm.Therewasnothingleftfortheenemytodobutsurrender.Thespywasbothhungryandcold;therewasnothingleftforhimbuttogivein.Ihadnochoicebuttowaittillitstoppedraining.下面一些短语是固定搭配,不带to:cannothelpbut,cannotchoosebut,cannotbut,donothingbut,havenothingtodobut。例如:Icannotbutadmirehiscourage.如果上述句中有do,to省略:IdidnothingbutwatchTVlastnight.如果是下面一个固定搭配,就带to:Ihavenochoicebuttogiveupmyidea.7)紧跟在why或whynot之后的动词不定式总是不带to。但是,紧跟在who,what,which,whether等连接词后的不定式带to。例如:Whystandupifyoucansitdown?Whynotaskyourteacherwhenyoudon'tunderstandthemeaning?Youneedn'tdecideyetwhethertostudyartsorscience.4.不定式的完成式和进行式1)构成完成式:to+havedone进行式:to+bedoing2)用法完成式:如果不定式所表示的动作(状态)发生在主要谓语动作之前,那么不定式就要用其完成式。\n进行式:如果主要谓语动作(情况)发生时,不定式所表示的动作正在发生,那么不定式就要用其进行式。例如:Shefeelsrelaxedtohavefinishedwritingherthesisbeforethedeadline.TheVikingsarebelievedtohavediscoveredAmerica.Whenyoucalledmelastnight,Ihappenedtobeworkingonthecomputer.5.不定式的被动形式当不定式的逻辑主语是动作的承受者时,不定式要用被动形式,包括它的一般式和完成式。例如:Fortwelveyears,SpanishcensorshipdidnotallowLorca'snametobementionedandhisworktobepublished.Thesnowwassupposedtohavebeenblownoffthemountain.6.不定式的否定形式否定形式是在不定式的标志to前加not。例如:Idecidednottoaskhimagain.Pleaseremembernottoleavethelightsonwhenyouareout.第五节动名词1.动名词的形式:动名词是由动词原形+ing构成(如writing),有完成时态和被动语态(如havingwritten,beingwritten)。2.动名词的用法动名词通常在句中作主语和宾语。1)动名词作主语Goingtothecollegeisthelittleboy'sdream.Keepingstudyinghardwillmakeyoupasstheexam.2)动名词作宾语有些动词后面只能带动名词作宾语,不能带不定式作宾语。此类动词常见的有:admit,acknowledge,anticipate,appreciate,avoid,consider,contemplate,defer,delay,deny,detest,dislike,ensure,enjoy,escape,excuse,evade,facilitate,fancy,favour,finish,forbid,imagine,include,keep,mind,miss,postpone,practise,resent,resist,risk,suggest,quit,worth等。例如:Johnwasconsideringbuyinganewcar.Ihopeyoudidn’tcontemplatecomingwithusonthistrip.Thewitnessdeniedhavingseentheaccusedman.Iwouldappreciateyourkeepingitasecret.3)某些短语后面只能接动名词,不能接不定式。此类短语常见的有:be(get)usedto,beaccustomedto,bededicatedto,bedevotedto,bebusy,becommittedto,besujectto,cannothelp,cannotresist,cannotstand,confessto,feellike,giveup,havetrouble(in),havedifficulty(in),haveagood/hardtime(in),havefun(in),haveanobjectionto,itisnogood/use,keepon,insiston,lookforwardto,objectto,payattentionto,putoff,resortto,succeedin等。例如:Icannotstandgettingupearlyinthemorning.Ihavenodifficulty(in)reachingthetopofthemountain.Thereisnousestayingon.Icannotresist(his)bargaining.Althoughpunctualhimself,theprofessorwasquiteusedtostudents’beinglateforhislecture.4)动词或短语后面也可以接动名词的被动形式。用主动形式还是被动形式,要根据句子的意思而定。例如:Carlosjustmissedbeingcaught.Thatpersonworedarkglassestoavoidbeingrecognized.Iobjecttobeingtreatedlikeachild.3.另一类动词后面可以带动名词做宾语,也可以带不定式作宾语。这类动词又可以分为两种:1)带动名词作宾语与带不定式作宾语而意义无多大区别的动词a)在begin,cannotbear,cease,continue,dread,like,love,neglect,omit,prefer,propose等动词之后,如表一般的行为,用动名词作宾语为多;如表示特定的或具体的动作,则用不定式结构作宾语为多。例如:\nIdon’tlikeswimming.Idon’tliketoswimthisafternoon.Johnprefersdoingithisway.Johnpreferstogooutingtomorrow.b)在begin,start等动词之后,如表示有意的动作,用动名词结构为多;如表示无意的动作,用不定式结构为多。例如:Aftersomehesitation,hebeganspeakingouthisownopinion.Ithasalreadybeguntorain.c)在attempt,intend,plan等动词之后,用不定式结构与用动名词结构意义相同,但以用不定式较为常见。例如:Heintendedtobuyanewcar.Heintendedtravellingabroadnextsummer.d)在encourage,permit,allow,recommend,advise,authorise等动词之后,一般用动名词作宾语,或者用不定式作宾语补足语。即:encourage/permit/allow/recommend/advise/authorise+doing,或encourage/permit/allow/recommend/advise/authorise+somebody+todo。例如:Headvisedgoingoutforawalk.Headvisedustogooutforawalk.e)在agree,decide等动词之后,可以直接跟不定式结构,但如果跟动名词,则动词后必须加适当的介词。例如:Heagreedtodomeafavor.=Heagreedondoingmeafavor.Intheendthemanagerdecidedtodoubletheadvertisingbudget.=Intheendthemanagerdecidedondoublingtheadvertisingbudget.f)在need,want,require,deserve等动词之后,可以用动名词的主动形式表示被动意义,这相当于用不定式的被动形式。例如:Thehouseneedsrepairing.=Thehouseneedstoberepaired.Thedisableddeserverespecting.=Thedisableddeservetoberespected.2)带动名词作宾语与带不定式作宾语而意义不同的动词a)动词remember,forget后可以跟不定式或动名词,但意义有明显区别:跟动名词,其动作发生在“记得”或“忘记”的动作之前;跟不定式,其动作发生在“记得”或“忘记”的动作之后。试比较:Irememberpostingthisletter.我记得这封信已经寄出了。Iremembertopostthisletterintheafternoon.我记得下午要将这封信寄走。b)动词regret后可以跟不定式或动名词,但意义有明显区别:regretdoing:为做过的事感到抱歉regrettodo:为即将要做的事感到抱歉试比较:IregrettosaythatIcannotgowithyouafterschool.Iregrethavingcriticizedyouseriouslyinclass.c)动词try,mean,cannothelp,usedto后跟不定式还是动名词,取决于这些动词本身的含义。例如:Youshouldtrytoanswerthequestionsbyyourself.(trytodo:设法或努力去做)Wetryusingthisnewmethod.(trydoing:试着做某事)ImeanttogototheexhibitionbutIforgot.(meantodo:is算做某事)Successmeansworkingvery,veryhard.(meandoing:意味着做某事)Ican'thelpapologizing.(cannothelpdoing:忍不住做某事)Ican'thelptoapologizeforhim.(cannothelptodo:不能帮助做某事)Mr.Smithusedtojoginthemorning,butnowhehasstopped.(usedtodo:过去经常或总是干某事)Inlandcanalsareusedtoshipfarmandfactorygoodstonearbytowns.(beusedtodo:被用来干某事)Iamnotusedtogettingupearlyinthemorning.(be/getusedtodoing:习惯于干某事)d)动词stop,continue,go\non,leaveoff之后,通常用动名词结构作宾语;如果用不定式结构,则不是宾语而是目的状语,相当于inorderto。试比较:Theystoppedworking.他们停止工作(来做其他事)。Theystoppedtowork。他们停止(做其他事)来工作。Thestudentswentonrecitingthetext.学生们继续背诵课文。Thestudentswentontorecitethetext.学生们停下其他事,继续背诵课文。Sheletoffdoingthehousework.她停止做家务(去干其他事)。Sheletofftodothehousework.她停止(干其他事)来做家务。动名词的逻辑主语问题动名词,顾名思义,具有名词的特点,即可以加物主代词和名词的属格来表示其逻辑(这时动名词的逻辑主语与句子主语不一致)。如果动名词的逻辑主语就是句子主语,不用加物主代词或名词的属格。例如:Thewatchmanreportedfindingthedooropen.=Thewatchmanreportedthathehadfoundthedooropen.此处,finding的主语与主句主语一致,都是thewatchman,所以finding前不加物主代词。Iappreciatedverymuchyourhelpingmethroughthetoughperiod.此处,helping的主语是you,而主句的主语是I,两者不一致,所以helping前的物主代词your不能省略。一般说来,能带动名词作宾语的动词都可以根据语义意图在动名词之前加上或略去主语。但有些动词,如excuse,forgive,pardon等,其后的动名词结构总是带有逻辑主语。这些逻辑主语通常由名词或代词宾格表示,也可由名词属格或形容词性物主代词表示。Idomindpeoplesmokinginpublicplaces.(名词宾格作逻辑主语)Wedon'tunderstandhimneedingsomuchmoney.(代词宾格作逻辑主语)Iwillneverforgivehisbetrayingmebybreakinghispromise.(物主代词作逻辑主语)Maryexcusedtheboy’supsettingtheink.(名词属格作逻辑主语)第六节分词1.分词的形式这里所讲的分词包括-ing分词和-ed分词,即传统意义上的现在分词和过去分词。现在分词由动词原形+-ing构成(如listening);过去分词通常由动词原形+-ed构成(如listened),但也有不规则形式(如go-gone)。现代英语的绝大多数都是规则动词,不规则的只是少数。2.分词的基本用法分词在句中通常可以用作表语、定语、补语和状语。下面按照现在分词和过去分词的用法分别作介绍。现在分词的基本用法:现在分词表示主动的意义;表示一般性的或正在进行的动作;在表现形式上有“一般式”和“完成式”与“主动式”和“被动式”之分,1)作表语现在分词作表语通常表示主语所具有的特征。例如:Thisstoryisquiteinteresting.Thejourneywithoutyouwillbeboring.2)作定语现在分词可以单独作定语,也可以构成合成词作定语,但在更多情况下是分词短语作定语,包括限定性和非限定性(用逗号与其他部分分开),在意义上相当于一个定语从句。现在分词作定语通常带有主动意义和未完成意义。例如:Themanfollowingwasobviouslyinahurry.(现在分词单独作定语)Theyactedjustlikeaconqueringarmy.(现在分词单独作定语)Doyouknowthemanstandingovertherebythedoor?(分词短语作限定性定语)Lastnight,wecaughtathiefstealingJohn’sbike.(分词短语作限定性定语)ThenameNebraskecomesfromtheOtoIndianword“ebrathka”,meaningflatwater.(分词短语作非限定性定语)3)作宾语补足语\na.表示感觉和心理状态的动词,如hear,feel,find,listento,lookat,watch,notice,observe,smell,see等词的宾语可以用现在分词作宾语补足语。例如:Inoticedhimslippingawaybeforetheendofthemeeting.Icansmellturkeyroasting,andit'smakingmehungry.b.表示“致使”等意义的动词,如catch,get,have,keep,leave,set等词的宾语可以用现在分词作宾语补足语。例如:WhatIsawjustnowsetmethinkingofmychildhoodinthecountryside.Pleasedon'tkeepthemachinerunningwhileyouareaway.4)作状语现在分词作状语表示主语在进行一动作的同时所进行的另一动作,它对谓语动词起修饰或陪衬的作用。这时要注意现在分词与其逻辑主语在时态和意义上的统一。例如:Rushingoutoftheroom,hewasknockeddownbyacar.(作时间状语)=Whenherushedoutoftheroom,hewasknockeddownbyacar.Workingharder,youwillpasstheentranceexam.(作条件状语)=Ifyouworkharder,youwillpasstheentranceexam.Shesatatawindow,readingabook.(作伴随状语)=Shesatatawindowandreadabook.Havingwonthechampionship,hewasawardedamilliondollars.(作原因状语)=Becausehehadwonthechampionship,hewasawardedamilliondollars.Eveniftakingataxi,Iwillstillbelateforthemeeting.(作让步状语)=Eveniftakeataxi,Iwillstillbelateforthemeeting.Theroadisunderconstruction,thuscausingthedelay.(作结果状语)=Theroadisunderconstruction,andthuscausedthedelay.注意,当现在分词作让步状语时,一般放在句首,常常由although,though,evenif,unless等连词引入;作结果状语时,一般放在句末,前面可以加so,thus,hence,thereby等副词。过去分词的基本用法:与现在分词不同,过去分词表示被动的意义,表示已经完成和被动的动作。在表现形式上,只有一种形式。1)作表语过去分词作表语表示主浯所处的状态。用作表浯的过去分词大多来自及物动词;不及物动词的过去分词能作表语的只限于少数表示位置转移的动词,如go,come,assemble等,它们用在连系动词之后,表示完成意义,无被动意义。例如:Themanlookedquitedisappointed.Heisgreatlydiscouragedbyherrefusal.Hishairisnearlyallgone.已经形容词化了的过去分词大多可作表语,常见的有:accomplished,amazed,amused,astonished,broken,closed,completed,complicatcd,confused,crowded,devoted,disappointed,discouraged,drunk,excited,frightened,hurt,interested,lost,satisfied,surprised,worried等。做定语a)前置定语的过去分词通常来自及物动词,带有被动意义和完成意义。例如:Welikeskatinginthefrozenlakeinthewinter.=Welikeskatinginthelakewhichhasbeenfrozeninthewinter.Howmanyfinishedproductshaveyougotuptonow?=Howmanyproductsthathavebeenfinishedhaveyougotuptonow?来自不及物动词的过去分词很少能单独用作前置定语,能作这样用的仅限以下几个词,这时仅表示完成意义,不表示被动意义:aretiredworker=aworkerwhohasretiredanescapedprisoner=aprisonerwhohasescapedafaded/witheredflower=aflowerthathasfaded\ntherisensun=thesunthathasjustrisenareturnedstudent=astudentwhohasreturnedvanishedtreasure=treasurethathasvanishedb)用作后置定语的过去分词通常也来自及物动词,表示被动意义和完成意义。这时相当于一个定语从句。例如:Thingsseenarebetterthanthingsheard.=Thingswhichareseenarebetterthanthingswhichareheard.Thelobsterbroiledovercharcoalwasdelicious.=Thelobsterwhichwasbroiledovercharcoalwasdelicious.做宾语补足语a)see,hear,feel,find,think等表示感觉和心理状态的动词可以带过去分词作宾语补足语。例如:Tomfoundhimselfinvolvedinanawkwardsituation.IsawTomdressedlikeabeggarinthestreet.Everybodythoughtthematchlostuntilthelastminute.d)make,get,have,keep等表示“致使”意义的动词可以带过去分词作宾语补足语。例如:Ihavemyclotheswashedeveryday.Don'tgetyourschedulechanged;staywithusintheclass.He’stryingtomakehimselfunderstood.Pleasekeepusinformedofthelatestprice.c)like,want,wish,order等表示希望、要求、命令等意义的动词可以带过去分词作宾语补足语。例如:Wedon'tlikesuchtopics(tobe)discussedinclass.Iwishthisproblem(tobe)solvedthisweek.4)作状语用作状语的过去分词通常来自及物动词。过去分词用作状语时,修饰主句的谓语动词,意义上相当于状语从句,表示时间、条件、原因、伴随状况等。过去分词作状语,前边往往可以加when,while,if,asif,though。一般说来,这种结构的逻辑主语必须与主句的主语一致。例如:Wheneverpraised,sheblushes.(作时间状语)=Wheneversheispraised,sheblushes.United,westand;divided,wefall.(作条件状语)=Ifweareunited,westand;Ifwearedivided,wefall.Writteningreathaste,thisbookisfulloferrors.(作原因状语)=Becausethisbookiswritteningreathaste,itisfulloferrors. Marywasreadingalovestory,completelylosttotheromanticlife.(作伴随状浯)=Marywasreadingalovestory,andwascompletelylosttotheromanticlife.AlthoughborninGermany,JohnlivesandworksinU.S.A.(作让步状语)=AlthoughJohnwasborninGermany,helivesandworksinU.S.A.3.分词的完成式及被动式前面提到过,过去分词只有一种形式,所以这里所讲的完成式及被动式均指现在分词的完成式及被动式。如果现在分词表示的是一般性动作,不表明动作的先后或与谓语动作同时发生,这时要用现在分词的一般形式。例如:Livinginthedowntown,wefoundalotofamusements.如果现在分词所表示的动作先于句子谓语发生,就要用现在分词的完成式“(not)having+过去分词”。例如:Havingheardfrommyfather,Iwasrelieved.Nothavingreceivedanyletterfrommyfamily,Iwasworried.如果现在分词的逻辑主语是现在分词所表示的动作的对象,则要用现在分词的被动形式,包括其一般形式“(not)being+过去分词”和其完成形式“(not)havingbeen+过去分词”。例如:Uponbeingquestioned,hedeniedhavingrobbedthebank.Thenewmethod,havingbeenwidelyusedabroad,canincreasetheworkingefficiency.\n4.分词独立结构如果过去分词或现在分词带有与句子主语不同的主语,这就构成了独立结构,也叫独立主格结构或垂悬结构,通常在句中起状语丛句的作用,表示原因、时间、条件、方式或伴随状况。例如:Theholidaysbeingover,theybegantogetdowntodotheirworkagain.(原因状语)=Astheholidaywasover,theybegantogetdowntodotheirworkagain.Allthingsconsidered,herpaperisofgreatervaluethanyours.(条件状语)=Allthingsareconsidered,herpaperisofgreatervaluethanyours.Hishomeworkdone,Johanwentouttoplay.(时间状语)=Afterhishomeworkhadbeendone,Johanwentouttoplay.Thegirlwassmilingsweetly,herlonghairflowinginthebreeze.(伴随状语)当独立结构表示伴随状况时,可变为由with引导的介词词组,而表示否定意义的类似结构便可由without引导。例如上例可变为:Thegirlwassmilingsweetlywithherlonghairflowinginthebreeze.Withoutanyonenoticing,Islippedoutoftheroom.独立结构的位置比较灵活,它可以置于句首、句中或句末。另外,独立结构中用作主语的名词之前的限定词有时可以省略。例如:Themanagersatquietlyinhisoffice,(his)eyesclosed.Hestoodinthedoorway,(his)wetcloakdrippingwaterontherug,andwaitedforsomesignofrecognition.第七节前后呼应主谓一致的基本原则主谓一致有以下三条原则:1)语法一致原则,即在语法形式上取得一致。例如,主语是单数形式,谓语动词也采取单数形式;主语是复数形式,谓语动词也采取复数形式。例如:Thestudentsareveryyoung.Thispicturelooksbeautiful.2)意义一致原则,即从意义着眼处理一致关系。例如,主语形式虽是单数但意义是复数,谓语动词也采取复数形式;而有些主语形式虽是复数但意义上看作单数,谓语动词也采取单数形式。Thepeopleinthatcountryarefightingforindependence.Thecrowddeeplyrespecttheirleader.Threeyearsinastrangelandseemsalongtime.3)就近原则,即谓语动词的单数或复数形式取决于最靠近它的词语。例如:NeitherhenorIamgoingtoseethefilmtonightbecausewearebusy.2.主谓一致的用法根据以上三条原则,主谓一致有如下用法:1)下列结构作主语,谓语动词一般用单数形式a.表示时间、重量、长度、价值的名词作主语,谓语动词通常用单数形式。例如:Twohundredmilesisalongdistance.Tendollarsisahighpriceforthatbook.b.由anyone,anything,anybody,noone,nothing,everyone,everybody,everything,someone,somebody,each,either,neither等不定代词作主语,谓语动词使用单数形式。例如:Someoneisknockingatthedoor.Anythingisbetterthangoingtothemovietonight.c.由“aseriesof,akindof,aportionof+名词”作主语,谓语动词应用单数形式。例如:Aseriesofdebatesisscheduledtobeheldnextweek.d.由“manya,morethanone+单数名词”作主语,尽管意义上表示复数,但谓语动词仍采用单数形式。例如:Manyapersoninthesecircumstanceshashopedforalongbreak.Thereismorethanoneanswertoyourquestion.e.“名词+and+名词”作主语,表示同一人、同一概念或事物时,谓语动词用单数形式。例如:\nAwriterandeducatorisgivingalecturenow.(这个人既是作家又是教育家)f.“either(neither)+of+复数名词(或代词)”作主语,谓语动词用单数形式。例如:Ifeitherofyoutakesavacationnow,wewillnotbeabletofinishthework.Neitherofthemwantstocome.g.在each…andeach…,every…andevery…等结构之后,谓语动词用单数形式。例如:Eachmanandeachwomanhastherighttovote.h.动词不定式、动名词或分句作主语时,谓语动词一般用单数形式。例如:WhatIwanttosayisnoneofyourbusiness.Listeningtotheclassicalmusicisenjoyable.i.以-ics结尾的复数名词指一门学科时,如politics(政治学),mathematics(数学),statistics(统计学),acoustics(声学),linguistics(语言学)等,谓语动词用单数形式。例如:Mathematicsiswhathemajorsin.2)下列结构作主语,谓语动词单复数形式取决于of后的名词。a.由“a11,none,no,most,half,thelast,therest,theremainder+of+名词”等不定代词作主语,谓语动词单复数形式由of后名词的单复数而定。例如:Noneofthefoodiswasted.Noneofthestudentswereabsent.Therestofthelecturewasdull.Therestofthebikeswereonsaleyesterday.b.由"lotsof,heapsof,loadsOf,scadsof+名词”作主语,谓语动词单复数形式由of后名词的单复数而定。例如:Lotsofworkistobedonethisweek.Lotsofpeoplearegoingtoswimthisafternoon.Thereisloadsofmilkonthefarm.Thereareloadsofbigredapplesontheground.Thereisheapsoffun.c.由“分数或百分数十of+名词或代词”作主语,谓语动词的单复数形式取决于of后名词或代词的单复数形式。例如:Three-quartersoftheareaiscultivated.Ninetypercentofthestudentshavepassedtheexam.3)下列结构作主语,谓语动词的单复数形式根据意义而定。a.由“the+形容词”这种结构作主语,根据意义一致的原则决定谓语动词的单复数形式。如果表示一类人(如therich,thepoor,theblind,thedeaf,thesick,theyoung,theold),谓语动词用复数形式;如果表示个人或抽象概念,谓语动词用单数形式。例如:Theblindaretaughttradesinspecialschools.(表示一类人)Thegoodinhimoverweighsthebad.(表示抽象概念)Thedepartedwasagoodfriendofhis.(表示个人)b.family,crowd,committee,class,audience,group,government,team,public,majority,minority等集合名词作主语,谓语动词单复数形式应根据意义而定。例如:Thefamilyliketolistentothemusic.(thefamily指这家人,用作复数)Thefamilyissmall.(thefamily指这个家庭,用作单数)Thecommitteehasconsideredyourproposal.(thecommittee指委员会,用作单数)Thecommitteewerearguingforanhourbeforetheygavetheirvotes.(thecommittee指委员会的委员们,用作复数)下列结构作主语,谓语动词一般单复数均可。a.以数词为名词词组中心词作主语时,谓语动词一般单复数均可。例如:Fiveandsixmake/makeseleven.Seventimestenareseventy.\n但是:Twentyfromthirtyleavesten.Sixsevensareforty-two.b.由"onein/outof+名词”作主语,谓语动词单复数均可。例如:Oneintenwere/waspresent.下列结构作主语,谓语动词用复数形式。由and或both…and连接两个单数形式的名词词组作主语时,一般谓语动词用复数形式。例如:Agirlandaboywanttogo.Bothriceandwheataregrowninthatcountry.6)下列结构作主语,谓语动词单复数形式视具体情况而定。a.由aswellas,togetherwith,besides,like,alongwith,withbut,except,accompaniedby,ratherthan,including连接两个名词作主语,谓语单复数形式应由连接词前的名词而定。例如:Thepresidentofthecollege,togetherwiththedeans,isplanningaconferencefor

beenthereforalongtime,hasn’tshe?Theymusthavestayedathomelastnight,didn’tthey?\n10)当陈述部分带有need时,反意疑问部分需视need的含义而定。如果need用作情态动词,则反意疑问部分用need形式;如果need用作实义动词,表示“需要”,则反意疑问部分用do形式。例如:Youneedn'tgothere,needyou?Sheneedstogothere,doesn’tshe?Plantsneedsuntogrow,don’tthey?11)当陈述部分带有I'dbetter或I’drather时,反意疑问部分用hadn't或wouldn't。例如:You'dbetterfinishthetaskbeforetomorrow,hadn’tyou?He’dratherstaywithus,wouldn'the?12)当陈述部分是祈使句时,反意疑问部分一般用willyou,won'tyou,wouldyou。例如:Don'tbetoolate,willyou?Closethedoor,won’tyou?Comehere,willyou?Openyourbooks,wouldyou?12)陈述部分是以Let’s开头的祈使句时,反意疑问部分用shallwe;若是以Letus开头的祈使句,反意疑问部分则用willyou。例如:Let’shaveapartytonight,shallwe?Letushavealookatyourpictures,willyou?注意,如果祈使句是否定形式,那么反意疑问句只能用willyou。例如:Don'tforgettobringyournotebooksheretomorrow,willyou?第九节强调句这里讲的强调句主要是以it为引导词的分裂句。它的结构形式是:It+be的一定形式+被强调成分+that-/who-分句(只有当被强调成分是句子的人称主语时,连接词才可以用who,此时也可以用that:其余情况下只能用that)。通过这种结构可以强调除谓语动词外的大多数句子成分。例如:ItwasMarythat/whoneededthecash.ItwasthecashthatMaryneeded.ItwasfromHenrythatJohnboughtthecar.ItwasthecarthatJohnboughtfromHenry.此结构可以强调多种多样的状语成分,例如强调时间状语、地点状语、方式状语,也可以强调由because引导的原因状语分句,但不可以强调由since/as引导的原因状语分句,也不可以强调由although和whereas引导的从属或并列分句。例如:Itwasbeforeliberationthatourpeoplesufferedfromtheimperialistaggression.ItisinIranthatthefamilymembersparticipateintheweddingpreparations.Itwasbecausehe'dneverhadtheopportunitythatJohnhadn'tlearnedtodrive.如果要强调谓语动词,通常采用另一种句型:主语通常是由what引导的名词性分句;分句的主动词通常是do的一定形式;主语补语通常是不定式结构,可带to,也可不带to。例如:Thepupilselectedhimmonitoroftheclass。强调谓语动词elected,变为:Whatthepupilsdidwaselect/toelecthimmonitoroftheclass.第十节虚拟语气虚拟语气是说话人为表示一种假设的情况或一种主观的愿望,即认为动词所表示的动作或状态并非事实或主观设想时所用的语气。虚拟语气的形式与用法:1.有一类虚拟语气的形式称为be型虚拟式,即不管主语是什么人称,动词一律用原形(或should+动词原形)。以下几种情况必须用be型虚拟式:1)一些表示命令,要求,决定,建议等概念的动词后由that引导的宾语从句中,必须用be型虚拟式。这类动词有:ask(要求),advise(建议),command(命令),decide(决定),demand(命令),insist(坚持),move\n(提议),order(命令),propose(提议),recommend(建议),request(要求),require(要求),suggest(建议),urge(极力主张)。例如:Westronglysuggestthathe(should)betoldaboutitearlier.Thedoctorinsistedthathispatienttakeiteasyforthreemonths.Irequirethattheycomebyten.Irecommendedthateachcompetitorreceive$100.Thejudgeorderedthatthewitnesstellthetruth.2)一些表示主张、要求、命令、愿望、建议等概念后的主语从句中,必须用be型虚拟式。此类词主要有:Itisnecessary,essential(重要的),advisable(应该的),appropriate(合适的),desirable(值得的),fitting(合适的),important(重要的),imperative(必须的),obligatory(必须的),proper(适当的),strange(奇怪的),urgent(紧要的),vital(极重要的)that…;Itis(was,hasbeen)suggested(decided,desired,ordered,proposed,requested)that…例如:Itishighlydesirablethatanewpresidentbeappointed.Itisimportantthateverybodyhavehishealthcheckedyearly.Ithinkitadvisablethatheleavesoon.Itisdecidedthatyoubethefirstonetodotheexperiment.3)一些表示主张、要求、命令等概念的名词后面由that引导的同位语从句中,通常用be型虚拟式。这类词主要有:advice,command,importance,idea,insistence,motion(提议),necessity,order,plan,proposal(建议),recommendation(建议),request,requirement,resolution(决议),suggestion,understanding(协议)。例如:Mysuggestionisthathebesenttohelpthisgroup.4)在lest,forfearthat或incase表示“生怕,以防万一,免得”引导的从句中,从句常常用should。例如:Hestudieddayandnight,lestheshouldfailinthetest.Wedarenotplayjokesonhimforfearthatheshouldbecomeangry.Bequietincaseyoushouldwakethebaby.5)某些表示祝愿、诅咒、禁止等的语句中用be型虚拟式。例如:Godblessyou!Goddamnyou!LongliveChairmanMao!Heavenforbid!2.下列两种句型,从句总是用一般过去式表示虚拟语气。1)Itis(high)timethat(该做……,必须做……),丛句用一般过去时。例如:Itistimethathewenttobednow.Itishightimethatthiswrongspendingwaschecked.2)wouldrather,wouldsooner,hadrather这些表示“宁愿”的短语后面的从句中的谓语动词应使用一般过去时表示虚拟语气。例如:Don'tcometoday.1wouldratheryoucametomorrow.Hehadratherhischildrendidn’tmakesomuchnoise.Iwouldsoonerwehaddinnernow.3.If引导的条件状语从句的虚拟语气用法If引导的从句的虚拟语气主要有三种结构:1)与现在情况相反:主句谓语用“would/could/might+动词原形”,从句谓浯用“动词的一般过去式”(be的过去式一律用were)。例如:IfIhadtime,Iwouldgowithyou.IfIwereyou,Imightrefusetheengagement.2)与过去情况相反:主句谓语用"would/could+havedone'’,从句渭语用“动词的过去完成式”。例如:IfIhadn’tlostmyway,Iwouldhavecaughtthelasttrain.Theywouldhavearrivedearlieriftherehadbeennostorm.\n3)与将来情况相反:主句谓语用"would/could/might+动词原形”,从句谓语用"wereto/should+动词原形”。例如:IfyouweretoseeMary,whatwouldyoutellher?IfIweretodoit,Iwoulddoitinadifferentway.Ifitshouldraintomorrow,Iwouldstayathome.4)省略if的虚拟语气句。虚拟条件从句中的谓语动词如果是were,should,had等词时,可以省略连词if,但必须将were,should,had等词移至主浯前形成句子倒装。例如:Hadhebeengivensomeinformationaboutit,hecouldhaveansweredthequestion.Wereyoutogetupearlier,youwouldn’tbelate.4.Wish后的宾语从句中的虚拟语气用法动词wish后跟由that引导的宾语从句(that经常被省略)要用虚拟浯气表示一种不可实现的愿望。1)宾语从句用过去式表示与现在事实相反。例如:IwishIhadenoughtimetofinishmyhomeworktoday.MybrotherisinEuropeonvacation,butIwishhewereherewithme.2)宾浯从句用过去完成时表示与过去事实相反。例如:Iwish1hadgonetothemovieswithyoulastnight.IwishProfessorLeehadtaughtmethisequation.3)宾语从句用“would/could+动词原型”表示一种愿望或要求。例如:Iwishthatyouwouldcomenexttime.Shewishesthatyoucouldstayherelonger.5.由asif/asthough引导的状语从句表示方式时,意思是“好像”,这时从句中的谓语动词应用虚拟语气。1)状语从句用过去式(be用were的形式)表示与现在的事实相反。例如:HetreatsmeasifIwereastranger.2)状语从句用过去完成式表示与过去的事实相反。例如:HetalkedasifhehadbeentoAustralia.6.介词或介词短语表示虚拟:有时假设的情况并不以条件从句表示出来,而是通过一个介词或介词短语来表示,或通过上下文表示出来。如butfor,butthat,with,without,otherwise,oncondition(that),incaseof,supposing,ontheunderstandingthat等表示让步假设。例如:IfIhadn’tgotyourhelp,Iwouldn'thavefoundmypresentjob.=Withoutyourhelp,Iwouldn'thavefoundmypresentjob.=Butforyourhelp,1wouldn'thavefoundmypresentjob.=Butthatyouhelpedme,Iwouldn'thavefoundmypresentjob.7.错综虚拟条件句:一般来说,主句和从句的谓语动词形式应前后呼应。但是有时主句和从句的动作发生的时间不一致,谓语动词的形式应作相应的调整,如:从句用过去虚拟语气,主句用现在虚拟语气(通常可以根据时间状语而定)。Haditnotbeenforthetimelyinvestmentfromthegeneralpublic,ourcompanywouldnotbesothrivingasitis.IfPaulhadreceivdsixmorevotesinthelastelection,hewouldbeourchairmannow.Ifyouhadstudiedtheproblemcarefullyyesterday,youwouldnotfindanydifficultynow.8.此外,还有省略了结果主句的虚拟语气ifonly结构,一般表示愿望。ifonly从句中的时态有三种:V+ed;be用were;情态动词用could/would/might+v。例如:Ifonlyhesawmenow!要是他现在能看到我那该多好!Ifonlyshehadnotbeenmarried!要是她没有结过婚就好了!Ifonlythecommitteewouldapprovetheregulationsandputtheminto第十一节、倒装\n倒装(inversion)是一种语法手段,用以表示一定句子结构的需要和强调某一句子成分的需要。英语的最基本的结构是主、谓结构,倒装就是将这种比较固定的词序加以颠倒。倒装有两种。将主语和谓语完全颠倒过来,叫做完全倒装(completeinversion)。如:Howgoesthetime?Thenbeganabitterwarbetweenthetwocountries.于是两国之间开始了恶战。只将助动词(包括情态动词)移至主语之前,叫做部分倒装。如:Atnotimewastheentranceleftunguarded.Seldomhavewefeltascomfortableashere.我们难得像在这里这么舒服。句子结构需要的倒装。为了句子结构的需要而进行倒装的情况有下列几种。1)疑问句。如:Areyoufromhere?Whowasthat?2)祝愿句。如:Longlivepeace!Mayyousucceed!Sobeit.就这样吧。3)某些感叹句。如: Theregoesthebell.打铃了。Herecomesthebus!Judith,howlovelyareyou![注]由副词there和here引导的倒装感叹句不可用人称代词,如不可说Herecomeshe.而须说Herehecomes。4)There+be结构。如:Therelivedanoldpeasantinthathouse.Thereseemstobesomemisunderstandingaboutthematter.5)其直接引语位于句首的陈述句。如:“It’stoolate,”saidMillian.“ThisisthehousewhereShakespearewasborn,”saidGeorge.6)地点状语位于句首、主语为名词而谓语为不及物动词的陈述句。如:Fromthewindowcamesoundofmusic.7)某些条件从句。如:HadIthetime,Iwouldgo.Wereyouinmyposition,youwoulddothesame.She’llbesixteencomeMay.到5月她就16岁了。Allright,ifstayyoumust,goandsitdownproperlyoverthere.好吧,如你必须留下,那你就在那里坐好。8)某些让步从句。如:LookasIwouldupanddown,Icouldseenohumanbeing.我尽管望上望下,还是看不到一个人。Toilashewould,hemightfall,andgodownandbedestroyed!他尽管苦干,还是可能失败、沉沦而被毁灭!Changeyourmindasyouwill,youwillgainnoadditionalsupport.你即使改变主意,也不会再得到援助。9)代词so,neither,nor等副词置于句首时,全句常需倒装。如:Ifyoucandoit,socanI.Ifyoudon'tgo,neithershallI.Idon'tknow,nordoIcare.10)Never,seldom,little,nor,hardly,scarcely,nosooner,notonly等表否定的副词或连词位于句首时,全句需要倒装。如:NeverinmylifehaveIseensuchathing.Seldomhavewefeltascomfortableashere.
