地点条件让步状语从句

定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。准确掌握每一个连词的含义是掌握状语从句的关键。同时要注意主从句的时态呼应。状语从句一般分为九大类状语从句类别:时间状语从句地点状语从句原因状语从句目的状语从句结果状语从句条件状语从句方式状语从句比较状语从句让步状语从句3.地点状语从句地点状语从句只有两个连词:Where,whereverWhere---在……地方Putthemedicinewhereyoucaneasilygetit.Wherethathighbuildingstands,thereusedtobesomelow,desertedhouses.Wherethereisawill,thereisaway.Wherever---无论哪里Hefollowsherwherevershegoes.Whereveryouare,Iwillberighttherewaitingforyou.2.条件状语从句引导状语从句的连接词有:If,unless,aslongas,incase,providedthat,onconditionthatIf---如果Ifyoudon’thurryup,youwillmisstheplane.Ifitsnowstomorrow,theflightwillbecanceled.Ifyouleaveat6o’clocktomorrowmorning,you’dbettergettobednow.Unless---如果不,除非=ifnotWecan’tgetthereontimeunlesswebooktheearliestflight=Wecannotgetthereontimeifwedon’tbooktheearliestflight.Don’ttroubletroubleunlesstroubletroublesyou.Hewillnotjoinusunlesshechangeshismind.Aslongas---只要Wewillsucceedaslongaswekeepontrying.Youcan’tplaygamesaslongasyouremembertherules.Amanisnotoldaslongasheisseekingsomething.As(so)faras---据……所知AsfarasIknow,hespeaksEnglishverywell.As/SofarasIknow,heisanexpertonDNA.Incase---假使,如果Theplanecannottakeoffincaseitrains.Sendusamessageincaseyouhaveanydifficulty.Providedthat如果,有时省略thatTheplanewillbeingoodconditionprovidedthatitistakencareofcarefully.Youcanbecomeastewardessprovidedthatyouareingoodshapeandyouhavegotthepropereducation.Onconditionthat---条件是…Hesaidthathewouldcometothemeetingonconditionthatnooneaskedhimtospeak.ThemotherpromisedtothesontobuyhimatoyairplaneonconditionthathepasseshisEnglishtest.注:主从句的动作发生在将来时，则主句用将来时,从句用一般现在时。Ifhearrivestomorrow,Iwillbewaitingforhimattheairport.Hesaidhewouldnotleaveunlessitwasfinenextday.8.让步状语从句引导让步状语从句的连词有：Although,though,as,evenif,eventhough,nomatter,however,whatever,while,whether（1）though,although表示“虽然，纵然”之意。这两个连词意思大致相同，在一般情况下可以互换使用。在口语中，though较常使用，although比though正式，二者都可与yet,still或nevertheless连用，但不能与but连用。例如：Though/Thoughhewaswornout,(still)hekeptonworking.虽然他已经精疲力竭了，但仍然继续工作。Although/Thoughheisveryold,(yet)heisquitestrong.他虽然年纪大了，身体还很健壮。值得注意的是，although引导的让步状语从句位于主句之前的情况较多，though引导的让步状语从句可位于主句之前或主句之后。例如：Shepassedtheexaminationthoughshehadnotstudiedveryhard.她虽然不用功学习，考试却及格了。（2）as,though表示“虽然……但是”，“纵使……”之意。as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形，though间或也用于这样的结构中，但although不可以这样用。Objectasyoumay,I’llgo(=Though/Althoughyoumayobject,I’llgo.)纵使你反对，我也要去。Hardas/thoughheworks,hemakeslittleprogress.(=Thoughheworkshard,hemakeslittleprogress.)尽管他学习很努力，但几乎没取得什么进步。Childas/thoughhewas,heknewwhatwastherightthingtodo.（=Thoughhewasachild,heknewwhatwastherightthingtodo.）虽然他是一个孩子，但他知道该做什么。Fastasyouread,youcantfinishthebooksosoon.纵然你读得快，你也不能这么快读完这本书。（3）evenif,eventhough表示“即使……”，“纵使……”之意。这两个复合连词的意思基本相同。它们常可互换使用，但意义有细微差别。evenif引导的让步从句含有强烈的假定性，而eventhough引导让步状语从句时，是以从句的内容为先决条件的，也就是说，说话人肯定了从句的事实。We’llmakeatripevenif/thoughtheweatherisbad.即使天气不好，我们也要作一次旅行。Evenifheispoor,sheloveshim.(=Hemaybepoor,yetsheloveshim.)即使他很穷，但她还是爱他。Eventhoughheispoor,sheloveshim.(=Heispoor,yetsheloveshim.)尽管他很穷，但她还是爱她。（4）whether...or...表示“不论是否……”，“不管是……还是……”之意。由这一个复合连词引导的让步状语从句旨在说明正反两个方面的可能性都不会影响主句的意向或结果。You’llhavetoattendtheceremonywhetheryou’refreeorbusy.不管你忙不忙，都要参加这个典礼。Whetheryoubelieveitornot,it’strue.无论你是否相信，这都是真的。（5）“nomatter+疑问词”或“疑问词-ever”的含义为“……都……；不管……都……”，它们引导的让步状语从句可以互换。Nomatterwhathappened,hewouldnotmind.(=Whateverhappened,hewouldnotmind.)无论发生了什么，他都不会介意的Nomatterwhoyouare,youmustkeepthelaw.(=Whoeveryouare,youmustkeepthelaw.不管你是谁，你都要遵纪守法。但“nomatter+疑问词”结构只能引导让步状语从句而“疑问词-ever”还可以引导名词性从句。Whatever(=Nomatterwhat)yousay,Iwon’tbelieveyou.(Whatever引导让步状语从句)无论你说什么，我都不会相信你。I’lleatwhatever(≠nomatterwhat)yougiveme.(whatever引导宾语从句)你给我吃什么，我就吃什么。Whoevercomeswillbewelcome.(Whoever引导主语从句)不管谁来都受到欢迎。此外，有时while也可以引导让步状语从句，但一般要位于句首。例如：WhileIlikethecolor,Idontliketheshape.我虽然喜欢那颜色，但不喜欢那形状。1.______you’vetriedit.youcan’timaginehowpleasantitis.（06北京）A.UnlessB.BecauseC.AlthoughD.When正确答案:Abe有时也可以引出一个让步状语从句，其意思是“不论…”。如：Beamaneversosuccessful,heshouldnotbearrogant.H不论一个人有多么成功,他不应该狂妄自大despite是“尽管”的意思，但只能作介词使用，可以用inspiteof来替换，后面只能接名词、代词或名词词组。尽管他病了，但他还是准时去上学。HDespitehisillness,hestillwenttoschoolontime.2.---Howlongdoyouthinkitwillbe________Chinasendsamannedspaceshiptothemoon?---Perhapstwoorthreeyears.（06福建）A.WhenB.untilC.thatD.before3.JennywasverysadoverthelossofthephotosshehadshotatCanada,thiswasamemorysheespeciallytreasured.（06广东）A.asB.ifC.whenD.where4.Youcan'thavethisfootballbackyoupromisenottokickitatmycatagain,theoldmansaidfirmly.（06广东）A.becauseB.sinceC.whenD.untilDＡD5.Ihadjuststeppedoutofthebathroomandwasbusilydryingmyselfwithatowel____Iheardthesteps.（06湖南）A.whileB.whenC.sinceD.after6.________environmentaldamageisdone,ittakesmanyyearsfortheecosystem(生态系统)torecover.（06江苏）A.EvenifB.IfonlyC.WhileD.Once7.Hewasabouthalfwaythroughhismealafamiliarvoicecametohisears.（06辽宁）A.whyB.whereC.whenD.while8._____hehaslimitedtechnicalknowledge,theoldworkerhasalotofexperience.（06全国I）A.SinceB.UnlessC.AsD.AlthoughBDCD9.Howcanyouexpecttolearnanything____youneverlisten?（06山东）A.incaseB.evenifC.unlessD.when10.Thisisaveryinterestingbook.I’llbuyit,_______
