123__________动/形/介连----------------------------.45—————动it(+adj./n.）--------------------.除此之外,v-ing也可以接宾语从句Realizing（that)itwasgettingdark,thedriverspedupandwenttohishomeasfastaspossible.宾语从句两点注意：1.语序：要用陈述句语序主+谓2.时态：主要取决于主句时态。主句是现在时，从句可以是任何时态；但主句如果是过去时态，从句也要用相应的过去时态。（客观真理除外）e.g.1）你能告诉我现在几点钟吗？2）没有人知道他住在哪里。3）你知道他们什么时候回到学校吗？Couldyoutellmewhattimeisitnow?Couldyoutellmewhattimeitisnow?Nobodyknowswheredoeshelive.Nobodyknowswherehelives.Doyouknowwhenwilltheycomebacktoschool?Doyouknowwhentheywillcomebacktoschool?×××4)妈妈说她要给我买个随身听。5）他告诉我说堪培拉才是澳大利亚的首都。6）我认为你不对。7）你认为张先生什么时候能回到我们公司？Mothersaidthatshewillbuymeawalkman.Mothersaidthatshewouldbuymeawalkman.ShetoldmethatCanberrawasthecapitalofAustralia.ShetoldmethatCanberraisthecapitalofAustralia.Ithink(that)youarenotright.Idon’tthink(that)youareright.DoyouthinkwhenMr.Zhangwillcomebacktoourcompany?WhendoyouthinkwillMr.Zhangcomebacktoourcompany?×××××WhendoyouthinkMr.Zhangwillcomebacktoourcompany?4.同位语从句的结构Hetoldmethenewsthatourteamhaswonthegame.________________先行词连---------------------------------------------.同位语从句与定语从句的区别：1)引导词不同，同位语从句只能用that引导，而且在从句中只起连接作用，不充当成分。不能用which,who,where,when,etc.引导2)先行词不同，同位语从句的先行词往往是抽象名词：news,fact,story,suggestion,…3)功能不同，同位语从句说明的是先行词的内容，而定语从句是对先行词的修饰与限制。比较：Thenewsthathetoldmeistrue.e.g.Hissuggestionthatwe’llgoforavisitonSaturdayisverygood.Hissuggestionthat/whichheputforwardatthemeetingisverygood.5.定语从句的三种结构1）ThisisthepenthatIboughtlastweek.2)ThepenthatIboughtlastweekismadeinChina.3)Hegavehermotherawatchforherbirthday,whichpleasedheralot.__________先行词连----------------------------.先行词连----------------------------—————————._________________________先行词——————，连---------------------1）2）为限制性定语从句，主从句之间没有逗号，关系紧密，从句对先行词起修饰和限制的作用。3）为非限制性定语从句，主从句用逗号隔开，从句是对先行词的补充、说明定语从句易犯的结构错误：e.g.1）你认识站在树底下的那个女孩吗？2）那个经常来这里帮我的那个男孩是我弟弟。3）你给我的那张邮票很有价值。Doyouknowthegirlisstandingunderthetree?Doyouknowthegirlwhoisstandingunderthetree?Doyouknowthegirlstandingunderthetree?Theboy,oftencomesheretohelpme,ismybrother.Theboy,whooftencomesheretohelpme,ismybrother.Thestampthatyougiveittomeisvaluable.Thestampthatyougivemeisveryvaluable.×××6.状语从句的两种结构（1）Becausehewasverybusy,hedidn’tcomehere.连-----------------------，————————.（2）Hedidn’tcomeherebecausehewasverybusy.________________连------------------------.状语从句就是用整个句子在复合句中作状语，修饰主句中的谓语动词、形容词和副词。状语从句—副词性从句。从结构上讲，表示地点、目的、结果、方式和比较的状语从句只能位于句末。但有些表示时间、条件、让步和原因的状语从句既可以位于句首，也可以位于句末，位于句首时，一般用逗号与主句隔开。e.g.1）IwaswatchingTVwhenmymothercamein.=Whenmymothercamein,IwaswatchingTV.2)Ifyouputyourheartintostudy,youwillmakegoodprogress.=Youwillmakegoodprogressifyouputyourheartintostudy.3)Although/Thoughheisveryyoung,heknowsalot.=Heknowsalotalthough/thoughheisveryyoung.=Youngasheis,heknowsalot.4)Hegotupearlythismorningsothathecaughttheearlybus.状语从句常见错误例析：1）尽管他已经七十多岁了，但仍然很强壮。2）我正在街上散步，突然看到了我的老朋友Tom.Although/thoughheisoverseventy,butheisstrong.

陈述句做名词性从句时，前面加上连词that，that只起连接作用，在从句中不充当成分。

Itiswell-knownthattheearthrunsaroundthesun.Thattheearthrunsaroundthesuniswell-known.Thetruthisthattheearthrunsaroundthesun.Noonedeniesthattheearthrunsaroundthesun.Youmustconfessthefactthattheearthrunsaroundthesun.主语从句表语从句宾语从句同位语从句2.一般疑问句：Doyouagreewithmyidea?Areyouinterestedinthegame?

一般疑问句做名词性从句时，需在前面加上连词whether/if（if只能引导宾语从句),还要把疑问语序改为陈述语序。Whetheryouagreewithmyideadoesn’tmattertome.Myquestioniswhetheryouagreewithmyidea.Iwonderwhetheryouagreewithmyidea.Theproblemwhetheryouagreewithmyideatroublesmealot.Itdoesn’tmattertomewhetheryouagreewithmyidea.主语从句表语从句宾语从句同位语从句3.特殊疑问句：Whatdoyouthinkofmyplan?Wheredoyoucomefrom?Whyareyousoupset?特殊疑问句做名词性从句时，就可以用原来的特殊疑问词来连接，不过这时特殊疑问词已经转化成了连接代词或连接副词。Whatyouthinkofmyplanisveryimportanttome.Iwanttoknowwhatyouthinkofmyplan.Myquestioniswhatyouthinkofmyplan.I’mthinkingaboutthequestionwhatyouthinkofmyplan.Itisveryimportanttomewhatyouthinkofmyplan.主语从句宾语从句表语从句同位语从句名词性从句的连接代词：who,whom,whose,what,which名词性从句的连接副词：how,when,where,why,howmany,howmuch,howlong,howoften,howold,howsoonwhoever,whomever,whosever,whatever,whichever正确使用名词从句的连接词：（1）如何区别that和what:e.g.1)_____hesaidatthemeetingistrue.2)______hemadeaspeechatthemeetingistrue.3)Hetoldme______hewouldgohikingthisSaturday.4)Hetoldme______hewoulddothisafternoon.WhatThat

thatwhat(2)如何区别which/whichever和what/whatevere.g.1)Iwanttoknow_____bookyouliketoread.2)Iwanttoknow______bookyouliketoreadbestofthethree.3)Therearemanybooks.Idon’tknow______Ishouldchoose.4)Allthetiesarehere.Youcanchoose____________youlike.(3）如何区别who与whoever,whom与whomever,whosever等词的用法e.g.1）Youcangivetheticketto_______wantstogotoseethefilm.2)Youcangivethetickettoanyone______wantstogotoseethefilm.3)BothmymotherandIhaveacar.Youcantake_______caryoulike.4)Infact,wealllike_________youlike.5)Infact,wealllikeanyone_______youlike.whatwhichwhatwhich/whicheverwhoeverwhowhoseverwhomeverwhom主语宾语定语(4)如何区别that和whether的用法e.g.1）Thereisnodoubt_____ourteamwillwinthegame.2)I’mnotsure________ourteamwilldefeattheirs.3)Itiscertain______ourcountrywillbecomemoreandmorepowerful.4)Thequestionis______theywillagreetoourplan.5)Thefactis______moreandmorepeoplehavegonetobigcities.语气肯定就用that;语气不肯定就用whetherthatwhetherthatwhetherthat(5)如何区别if和whether的用法：e.g.1)Thequestionis_______theywillcomehereontime.2)Ididn’tknow_____________shewasready.3)Ididn’tknow__________shewasreadyornot.4)________hewillcomeheremakeslittledifference.5)Itmakeslittledifference___________hewillcomehere.6)Itdependson___________theyhaveenoughmoney.7)Theproblem_________weshouldgotherehasbeendecided.在名词性从句中，if只能引导It做形式主语的主语从句5）；动词后面的宾语从句3）在表语从句和同位语从句中，只能用whether不能用if;在主语从句中，在句首不能用if,只能用whether,与ornot连用只能用whether；做介词宾语，只能用whether,不能用if;与动词不定式连用，只能用whether。whetherwhether/ifwhetherWhetherwhether/ifwhetherwhether

Ⅱ.引导定语从句的连词（关系代词和关系副词）引导定语从句的关系代词有that,which,as,who,whom,whose;关系副词有when,where,why.关系代词在定语从句中做主语、宾语和定语，关系副词在定语从句中作状语1.区分关系代词和关系副词Thisistheplace____________Ioncevisited.Thisistheplace_______Ionceworked.2.区分that和which:(在从句中做主语和宾语，都可以指物）Thereisnothing_____I’mworriedaboutyou.2)Thisisthemostbeautifulpark_____I’veeverseen.3)Isitthesecondtime_____youhavecomehere?4)Wetalkedalotaboutthepeopleandthethings_____wesaw.5)Itistheverypen_____I’mlookingfor.6)Whichisthebook_____yougavemeyesterday?that,which,/wherethatthatthatthatthatthat只能用that,不能用which的六个字：代、高、序、双、特、重代：先行词是不定代词时，much,little,none,all,few,everything,anything,nothing,etc.高：先行词被形容词最高级所修饰序：先行词是序数词或被序数词所修饰双：先行词既有人又有物时特：先行词被特定词修饰，theonly,thevery,justthe,etc.重：重复指代，当主句以which开头时。1)Thewalkman,____Iboughtlastweek,ismadeinourhometown.2)Thisisthepenwith_____Ioftenwritetomyfather.3)Idon’tlikethat_____istooexpensive

只能用which,不能用that:逗号之后;介词之后;先行词为that,或被that修饰whichwhichwhich3.何时用whose:在定语从句中，whose既可指“某人的”，又可指“某物的”，作定语，后接名词e.g.1)我喜欢那辆蓝色的小轿车。2)这就是那个女孩。她妈妈在我们学校工作。Ilikethecarwhichcolourisblue.Ilikethecarwhosecolourisblue.Ilikethecar,thecolourofwhichisblue.Ilikethecar,ofwhichthecolourisblue.Thisisthegirl,hermotherworksinourschool.Thisisthegirlwhosemotherworksinourschool.Thisisthegirl.Hermotherworksinourschool.Thisisthegirlandhermotherworksinourschool.××复合句简单句并列句4.非限定性定语从句的连接词which,who,whose,as,when,where,e.g.1)Thisistheschool,_______Istudiedforthreeyears.2)Istillrememberthedayonthefarm,______wehelpedthefarmers.3)Thisreportwillbegivenbyaprofessor,_____isfromCanada.4)Manypeopledonatedmoneyforthegirl,______motherwasseriouslyill.wherewhenwhowhose5.用which还是用as:as引导非限定性定语从句，指代整个主句的内容,在从句中作主、宾或表语，可以放在句首，或主句之后，放在主句后面时也可以用which.“as”的意思是“正如”，“which”的意思是“这一点”。e.g.Johnpassedtheexam,as/whichweallexpected.但以下情况只能用as:1）当先行词前有such,thesame修饰时2）当非限定性定语从句放在句首时Itissuchaninterestingfilmaswealllike.(as引导定语从句，做like的宾语）=Itissuchaninterestingfilmthatwealllikeit.（结果状语从句）Asisknowntoall,BeijingisthecapitalofChina.=BeijingisthecapitalofChina,as/whichisknowntoall.但是，Herfatheristoohardonher,whichshecan’tbear.Hesentmeabeautifulgift,whichIlikeverymuch.她爸爸对她太苛刻，这一点他受不了。他送给我一个很精美的礼物，（这个礼物）我非常喜欢6.怎样把握“介词+whom/whose/which”的用法e.g.1)Thisisthefarm,onwhichIstayedforthreedays.2)ThecomputerforwhichIpaidthreehundreddollarsworksverywell.3)Godownthestreet,attheendofwhichyoucanseeahighbuilding.4)DoyouknowthegirlwithwhomIshookhandsjustnow?5)ThisisMr.Smith,inwhosedepartmentmyuncleworksasamanager.6)I’llneverforgettheevening,onwhichImetanoldfriendofmine.“介词+whom”只能指人，“介词+which”只能指物，“介词+whose”既能指人，又能指物。至于关系代词前面的介词，要看先行词与从句谓语动词的相关搭配以及整个句子的意思来定。Ⅲ.状语从句的连接词时间状语从句：时间状语从句中常见的连接词较多，可分为：（1）基本类before,after,when,while,as,since,till,until,once,assoonas….难点：when,while,as的区别：when既可以和短暂性动词连用，又可以和连续性动词连用；while只能和延续性动词连用，且多用进行时；as多强调“一边…一边…”）When/whileIwasworkingthereImadealotoffriends.2)MotherwascookingsupperwhenIcamein.=Icameinwhile/whenmotherwascookingsupper.3)Asthechildrenwalkedalongthestreet,theysanghappily.once和before:4)Onceyouseetheman,youwillneverforgethim.5)TheboyrushedoutbeforeIcouldsayaword.不能换成while(2)名词类：即由名词词组充当引导词（用作连词），如：themoment,thesecond,theinstant,theminute,

均相当于“assoonas…”e.g.1)I’llgiveyouaphonecallthemomentIgetthere.2)Theminutetheyarrivedatthespot,theygetdowntoputtingoutthefire.

（3）副词类：三个副词可以做名词用，immediately,directly,instantly,也相当于“一…就…”e.g.1)Thechildrenrushedoutimmediatelytheyheardthenews.2)IwenthomedirectlyIfinishedmyhomework.

(4)短语类：有几个time短语,如：everytime,eachtime,thenexttime,anytime,thefirsttime,thelasttime…e.g.1)ThefirsttimeIsawher,shewasplayingbadminton.2)EverytimeIstayedwithhim,Iwastouchedbyhiswords.(5)句型类：常见的句型有，Somebodywasabouttodo…when…Somebodywasdoing…when…Somebodyhadjustdone…when…Hardly…when…Nosooner…then…e.g.1)Hardlyhadwegoneoutwhenitbegantorain.2)IwasjustabouttoleavewhenIheardmynamecalled.3.原因状语从句：原因状语从句的连接词主要有because,since,as,nowthat=since,也可以用seeingthat（鉴于）,consideringthat（考虑到），forthereasonthat(因为）难点:表原因的连词since,because,as,for的区别：Because引导的从句强调因果关系，语气最强，常用来回答why的问题，位置可在主句之前或后。Since和as引导的从句一般位于主句之前,表示比较明显或已知的原因；For是一个并列连词，只能放在一个分句之后,对这个分句作补充说明Marywaslateforthefirstclassbecauseshegotuplate.Sinceyouarealeaguemember,youshouldbestrictwithyourself.Asitisraining,let’sstoptohavearest.Nowthat(since)everybodyishere,let’sbeginourmeeting.2.地点状语从句：连接地点状语从句的连接词只有where和wherever.e.g.1)Weallliketolivewherethereisfreshairandcleanwater.2)Whereveryougoyoushouldmindyourbehaviors.难点：注意区分地点状语从句与where引导的定语从句:e.g.1)他在丢失的地方找到了计算机。2）读书时，你最好在有问题的地方做个记号。3）你应该定个规矩，把东西放在你能找到的地方。Shefoundhercalculatorwhereshelostit.Shefoundhercalculatorintheplacewhereshelostit.Whenyoureadthebook,you’dbettermakeamarkwhereyouhaveanyquestionWhenyoureadthebook,you’dbettermakeamarkintheplacewhereyouhaveanyquestions.Youshouldmakeitaruletoleavethingswhereyoucanfindthemagain.Youshouldmakeitaruletoleavethingsintheplacewhereyoucanfindthemagain.4.条件状语从句：条件状语从句主要由if,unless,as/solongas,incase,ifonly,provided/providingthat(假若）,onconditionthat,suppose/supposing,assuming等引导。考点：在条件状语从句中，如果主句的时态是一般将来时，从句用一般现在时。1)You’llbelateagainifyoudon’thurry.=You’llbelateagainunlessyouhurry.2)Youmayusemycomputerso/aslongasyoutakegoodcareofit.=Youmayusemycomputeronconditionthat…3)Suppose/supposing/assuminghecomes,whatshallwedo?5.比较状语从句：比较状语从句通常由as…as…,notso/as…as,more…than,themore…themore…等引导。重点：掌握as…as…四大句型：1）“as+adj./adv.+as”句型：2)“倍数+as+adj.+as”句型可与“倍数+the+n.+of”互相转换TomisastallasBob(is),buthedoesn’trunso/asfastasBob(runs).Myunclejumpsashighasmyfather(jumps).Theirclassroomisthreetimesasbigasours(is).=Theirclassroomisthreetimesthesizeofours(is).Thisbridgeistwiceaslongasthatone.=Thisbridgeistwicethelengthofthatone.ashighas=theheightof,aswideas=thewidthof,asmuchas=theamountof,asdeepas=thedepthof“asmany+可数名词+as”“asmuch+不可数名词+as”Therearepilesoftiesandyoucantakeasmany(ties)asyoulike.MyfriendJohnboughtasmanybooksasIyesterday.Youcaneatasmuchasyoulike.Atthepartyshedrankasmuchbeerastheboys.Maryearnsasmuchmoneyinthecompanyasherhusband.as…as…还有以下两个相关句型，但不属于状语从句“as…manyas+数词+可数名词”“as…muchas+数词+重量金钱名词”Hesentasmanyas50postcardsatatimebeforeNewYear’sDay.Theirfamilyhasasmanyasfivecars.Hespentasmuchas500dollarsonclothestoday.Mumboughtasmuchas8kilogramsofapplestoday.6.方式状语从句：方式状语从句主要由as,asif/though等引导WheninRome,doastheRomansdo.Irememberthewholethingasif/thoughithappenedyesterday.7.目的状语从句：主要由inorderthat,sothat,incase,forfearthat引导，谓语部分常由“情态动词can/could,may/might,will/would+动词原形”构成Theyareworkinghardsothattheycanmakeabreakthroughinthisfield.Theboyworksveryhardinorderthathecancatchupwithothers.Don’tstayoutinsuchbadweatherincaseyoucatchacold.简单句=Theyareworkinghardsoastomakeabreakthroughinthisfield.=Theboyworksveryhardinordertocatchupwiththeothers.简单句Don’tstayoutinsuchbadweatherforfear(that)youmightcatchacold.8.结果状语从句：引导结果状语从句的连接词有sothat,so…that..such…that…,withtheresultthat等。结果状语从句有两个难点：1）结果状语从句和目的状语从句的区别Theboystudiedveryhardsothathecaughtupwithhisclassmates.=Theboystudiedsohardthathecaughtupwithhisclassmates.Theboystudiedveryhardsothathecouldcatchupwithh
