初中状语从句讲解及习题附答案

（一）状语从句概述定义状语从句用作状语，是起副词作用的句子。位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用逗号和主句隔开。分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。（二）状语从句详解1.时间状语从句引导词用法示例when意为“当…的时候”。When引导从句的谓语动词可以是延续性动词，也可以是瞬间动词。并且when有时表示“就在那时”Aliarisnotbelievedwhenhespeaksthetruth.说谎者讲真话时也没有人相信。Whenhearrives,I’llcallyou.Whenyoulaughandsmile,yourbodyrelaxes.while意为“在…的时候，在…的同时”。While引导从句的谓语动词必须是延续性的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While有时还可以表示对比。WhileIwasstandingatthewindow,Isawseveralboysrunningalongthestreet.WhileJohnwaswatchingTV,hiswifewascooking.as意为“一边…一边…”。As引导的动作是延续性的，发生时间较短，一般用于主句和从句动作同时发生；as也可以强调一前一后。ThewriterwasangryashewastravellingonatraintoLondonbecausesomeonehadinvadedhis“space”.Hesmiledashestoodup.after意为“在…之后”。表示主句动作发生在从句动作之后。主句与从句的动作时间关系与before引导的从句相反。Withmanyhungryvisitorswaiting,don’tstaytoolongatyourtableafteryouhavefinished.Ifanearlyexitisnecessary,youcanleaveafterasceneisover.before意为“在…之前”。引导的从句不用否定形式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作的先后。Youcan’twatchTVbeforeyoufinishyourhomework.Beforeitended,thetheatrewasalmostempty.MyfatherhadleftforCanadajustbeforetheletterarrived.till意为“直到”。一般情况下可以和until互换。如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定和否定形式都可以，但表达的意思不同。Shedidn’tevenknowthatitwasanearthquaketillshesawashaking(movingfromsidetoside)light.Thefiremanworkedveryhardtillthefirewasout.until意为“直到”。在强调句型中多用until。如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定和否定形式都可以，但表达的意思不同。I’mwaitingformysister.Iwon’tgotoseemyuncleuntilshecomes.WaituntilIfinishwhatIamdoing.since意为“自从，从…以来”。引导从句的谓语动词可以是延续性的动词，也可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。但在Itis+时间+since从句的句型中，主句多用一般现在时。IhavebeenstudyinghardsinceIenteredthehighschool.ItisfouryearssincemysisterlivedinBeijing.ItisfiveyearsmonthssinceourbosswasnotinBeijing.assoonas意为“一…就…”。引导时间状语从句时，如果主句用了将来时，从句一般使用现在时。Tomwillcallmeassoonashegetshome.IwillcallyouassoonasIarrive.2.地点状语从句引导词用法示例where意为“哪里”。“where引导的地点状语从句，（there+）主句”“哪里…哪里就…”。主句在从句后面时，there可用可不用；主句在从句的前面时，一般都不用there.Wherethereisawill,thereisaway.Theyweregoodpersons.Wheretheywent,theretheywerewarmlywelcomed.Youshouldhaveputthebookwhereyoufoundit.wherever意为“无论何地”。anywhere/wherever引导地点状语从句+主句。anywhere本身是个副词，但是常可以引导从句，相当于连词，意思相当于wherever,anywhere引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。Wherevertheseais,youwillfindseaman.I’llgoanywhereyougo.3.条件状语从句引导词用法示例if连词，意为“假如，如果”。当主句是将来时的时候，从句要用一般现在时。Don’ttalkloudlyatthemeeting.Ifyoudo,youwillhavetoleave.We’llgoforapicnicifitdoesn’trainthisweekend.unless连词，意为“除非（=ifnot）。当主句是将来时的时候，从句要用一般现在时。Don’tdiscusstheproblemswithyourpartnerunlessyouareaskedtodoso.Iwon’tgothereunlessyoucomewithme.4.原因状语从句引导词用法示例as意为“因为”。引导原因状语从句时表示附带。说明“双方已知的原因”，语气比since弱，较为正式，位置较为灵活（常放于主句之前）。Astheweatheriscold,Istayathome.Asitisraining,you’dbettertakeataxi.Asyouaretired,you’dbetterrest.since意为“因为”。引导的原因状语从句一般放于主句之前表示已知的、显然的理由（通常被翻译成“既然”），较为正式，语气比because弱。Sincetheearthlookslikeaball,thesuncanshineononlyhalfofitatatime.SincetheraceisinApril,Ihadtorunthroughoutthewinter,andinBoston,wintersarecold.Sinceeverybodyishere.Let'sbeginourmeeting.because意为“因为”。引导的原因状语从句一般放于主句之后，表述直接原因，语气较强，最适合why引导的疑问句。Because引导的原因状语从句有时可以与becauseof短语互换。Thewomanpreferswinterbecauseshecanskate.I’dliketocollectstampsbecausetheyareinteresting.I’mverytiredthesedaysbecauseofstudyingphysics.Hecan’tcomebecauseheisill.=Hecan’tcomebecauseofhisillness.for意为“因为”。引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for引导的原因状语从句只能放于主句之后，并且必须用逗号将其与主句隔开。Hemustbeill,forheisabsenttoday.Hecouldnothaveseenme,forIwasnotthere.5.目的状语从句引导词用法示例sothat意为“以至，以便”。目的状语的谓语常含有may,might,can,could,should,would等情态动词。Trytospeakloudenoughsothatpeoplecanhearyouclearly.Mr.Greenspeaksveryloudlysothatallthepeoplecanhearhimclearly.inorderthat意为“为了”，相当于sothat.inorderto后面可以跟动词原形构成目的状语，不是目的状语从句。Weshallletyouknowthedetailssooninorderthatyoucan/maymakeaarrangements.6.结果状语从句引导词用法示例so…that意为“如此…以至于…”。so+adj./adv.原级+that,so是副词，只能修饰形容词和副词。so还可与表示数量的形容词many,few,much,little(这四个形容词表示多或少时)连用,形成固定搭配。so+many或few+复数可数名词+that;so+much或little+不可数名词+that.ThisyearithasrainedsoheavilyinSouthChinathatlotsofproblemsarecaused.Theiceonthelakewassothinthatpeoplecouldn’tskateonit.Toooften,wespendsomuchtimethinkingaboutthefuturethatwefailtoenjoythepresent.TherearesofewnotebooksthatIcan’tgiveyouany.such..that意为“如此…以至于…”。有三种结构：such+a(an)+adj.+单数不可数名词+that;such(+adj.)+不可数名词+that;such(+adj.)+复数可数名词+that,such是形容词，修饰名词或名词词组。有时可与so…that句型转换。It’ssuchawonderfulsongthatwealllikeit.Simonissuchdishonestpersonthatnoonebelieveshim.Theboyissoyoungthathecan’tgotoschool.=Heissuchayoungboythathecan’tgotoschool.7.让步状语从句引导词用法示例though意为“虽然”。不能和but连用。但是可以同yet(still)连用，构成though…yet(still).though较普遍，常用于非正式的口语和书面语中。even能和though组合表示强调，在这里eventhough=evenif(nomatterif;though即使…也…)。though可以独立用作副词，常放在句末，意为allthesame(还是；仍然)或however(可是；然而)。Soithasliveduptonowthoughitisn'tstrongatall.Thoughtheyaretwinbrothers,theydon’tlooklikeeachother.Evenif/Eventhoughwecouldaffordit,wewouldaffordit,wewouldn’tgoabroadforourvacation.although意为“虽然”。不能和but连用。但是可以同yet(still)连用，构成although…yet(still).although较为正式，语气比though重，常用以强调让步概念。even不能和although组合。Althoughhediedseveralyearsago,Icanstillrememberthedayswespenttogetherandwhathehastaughtmeaboutlove.Althoughwehadlittlefoodwithus,wedecidedtospendthenightinthecar.8.比较状语从句引导词用法示例as…as...意为“和…一样”。表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+adj./adv.原级+as。若有修饰成分，如twice,threetimes,half,aquarter等，则须置于第一个as之前。Sheisverygoodatpainting.Shecanpaintaswellashereteacher.Iranoutasquicklyaspossible.notas/so…as意为“和…不一样，不如”。也表示同级比较。Sheisnotso(as)outgoingashersister.Thisdictionaryisnotas/sousefulasyouthink.9.方式状语从句引导词用法示例as/(just)as...so…意为“犹如，就像”。引导的方式状语从句通常位于主句后，但在(just)as...so…结构中位于句首，这时as从句带有比喻的含义，意为“正如…，就像”，多用于正式文体。WheninRome,doastheRomansdo.Aswateristofish,soairistoman.asif/asthough意为“就像，好像”。两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。常译作“仿佛…似的，好像…似的”。Ifwouldneverforgetheresmile,orthewayhereyesshoneasifwewerethesameage.Itlooksasiftheweathermaypickupverysoon.练习一一.单项填空1._______he’sold,hecanstillcarrythisheavybag.A.ThoughB.SinceC.ForD.So2.---Doyouknowifhe_______toplaybasketballwithus?---Ithinkhewillcomeifhe______freetomorrow.A.comes;isB.comes;willbeC.willcome;isD.willcome;willbe3.Inthezooifachild_____intothewaterandcan’tswim,thedolphinsmaycomeup______him.A.willfall;tohelpB.falls;tohelpC.willfall;helpD.falls;helping4.Idon’tremember________heworkedinthatcitywhenhewasyoung.A.whatB.whichC.whereD.who5.Wewillstayathomeifmyaunt________tovisitustomorrow.A.comesB.comeC.willcomeD.iscoming6.Thepoliceaskedthechildren_______crossthestreet________thetrafficlightsturnedgreen.A.not;beforeB.don’t;whenC.notto;untilD.not;after7.Iwaslateforclassyesterday_______therewassomethingwrongwithmybike.A.whenB.thatC.untilD.because8.I’llgoswimmingwithyouifI________freetomorrow.A.willbeB.shallbeC.amD.was9.Intheexam,the________youare,______the_______mistakesyouwillmake.A.careful;littleB.morecareful;fewestC.morecareful;fewerD.morecareful;less10.Youshouldfinishyourlessons_______yougoouttoplay.A.beforeB.afterC.whenD.while11.Ihurried_____Iwouldn’tbelateforclass.A.sinceB.sothatC.asifD.unless12.Whenyoureadthebook,you’dbettermakeamark_______youhaveanyquestions.A.whichB.thatC.whereD.though13.Theteacherraisedhisvoice_______allthestudentscouldhearhim.A.forB.sothatC.becauseD.inorder14.Hetookoffhiscoat_______hefelthot.A.becauseB.asC.ifD.since15.Itis______thatwe’dliketogooutforawalk.A.alovelydayB.toolovelyadayC.solovelyadayD.suchlovelyaday16.Maryhad______muchworktodothatshestayedatherofficeallday.A.suchB.soC.tooD.very17._______Ifeltverytired,Itriedtofinishthework.A.AlthoughB.BecauseC.AsD.Asif18.______thedaywenton,theweathergotworse.A.WithB.SinceC.WhileD.As19.______wellyoucandrive,youmustdrivecarefully.A.SolongasB.InorderthatC.NomatterhowD.Themoment20.Writetomeassoonasyou________toBeijing.A.willgetB.getC.gettingD.got二.根据中文意思完成下列
