状语从句状语从句复习状语从句不仅是初中英语学习的重点,而且也是每年中考必考的内容之一。从历年全国各地中考英语试题对状语从句的考查内容来看,命题主要集中在引导状语从句的连词、状语从句的时态等方面;从九大状语从句来看,同学们应将复习重点放在时间状语从句、条件状语从句、结果状语从句和比较状语从句这四种上。一、对时间状语从句的考查引导时间状语从句的连词有:while,when,as,assoonas,until,not…until,before,after,since,etc.要掌握每个连词的含义及其用法,还有它们之间的一些区别。when,while的区别:①二者均可表示“当……的时候”,如果主句表示的是短暂的动作,而从句表示的是一段时间,二者可通用。如:ImetKangLiwhen/whileIwaswalkingalongthestreet.当我沿街散步时碰见了康丽。②when可与终止性动词连用,while只能与延续性动词连用。如:Itwassnowingwhenwegottotheairport.当我们到达机场时,天正下着雪。(不能用while)③while强调主句表示的动作持续于while所指的整个时间内;when可指主、从句所述动作同时或先后发生。如:PleasewritewhileIread.我读的时候,请写下来。Whenhereachedhome,hehadalittlerest.回到家后,他休息了一会儿。3)until=till在肯定句中表示“直到……为止”,主句要用延续性动词;在否定句中,表示“直到……才”,主句常用终止性动词,这时till和until可用before替换。如:Iwaitedtill/untilhearrived.我一直等到他到来。Wewon'tstartuntil/till/beforeBobcomes.鲍勃到来之前,我们不会动身。4)since从句中常用过去时,主句用一般现在时或现在完成时;assoonas如果主句是一般将来时,情态动词加动词原形或祈使句时,时间状语从句用一般现在时。如:WherehaveyoubeensinceIsawyoulast?上次我和你见面之后,你到哪里去了?I’llphoneyouassoonasIarriveinTonghua.我一到通化就给你打电话。2.考例:1)我一到美国就给你打电话。(北京市海淀区)I'llringyouup__soon__IgettoAmerica.2)昨天直到雨停了,孩子们才离开学校。(同上)Thechildren______leaveschool___therainstoppedyesterday.asasdidn’ttill3)It______tenyearssincethey______toFrance.(河北)A.as;coveredB.was;havemovedC.is;havemovedD.is;movedD4)He______waituntiltherain______.(南京市)A.won't;willstopB.won't;stopC.will;stopsD.will;willstopC5)Whenallthework_____(finish),youmaygobackhome.6)Mybrother____(begin)tolearnEnglishwhenhewaseight.7)Please_____(notleave)hereuntilyou_____(tell)to8)Assoonashe_____(get)there,hewillwritetousatonce.9)Hetookoutthecameraassoonashe_____(see)themonster.10)Ioften____(go)toseeherwhenshewasill.11)Pleasedon’ttalksoloudwhileothers_____(work).12)Where____you____(study)beforeyouwenttocollege?二、对条件状语从句的考查1.要点:引导条件状语从句的连词有if(如果),unless在意义上相当于if...not。条件状语从句也像时间状语从句一样,如果主句用将来时,从句要用现在时代替将来时。如:Youwillfailunlessyoustudyhard.(=Youwillfailifyoudon’tstudyhard.)除非你努力学习,否则你会失败。2.考例:1)HewillgototheGreatWallifit______tomorrow.(北京市宣武区)A.won'trainB.doesn'trainC.don'trainD.isn'trainingBC2)______youeatoldfood,youmaybeill.(湖南)A.BeforeB.WhyC.IfD.Which三、对比较状语从句的考查1.要点:引导比较状语从句的连词有as...as,than。1)表示甲与乙在某一方面相同时,用“as+原级+as”句型;表示甲在某一方面不如乙时,用“notas/so+原级+as”句型。如:DalianisasbeautifulasShenzhen.大连和深圳一样的美。Idon'trunas/sofastasKangLi.我不如康丽跑得快。2)表示甲超过或不及乙时,用“比较级+从句”(从句中常省略意义与主句相同的部分)。如:Herunsfasterthanyou(do).他跑得比你快。Todayislesscoldthanyesterday.今天没有昨天冷。2.考例:1)Jackrunsas____asTom.(北京市宣武区)A.fastB.fasterC.fastestD.muchfasterA2)30,000dollarsisalargeamountofmoney,butit's______thanweneed.(上海市)A.formoreB.verymuchC.farlessD.verylittleC四、对结果状语从句的考查1.要点:引导结果状语从句的连词有so…that(如此……以致于),such…that(如此……以致于)等。常用句型:so+形容词/副词+that从句sucha/an+形容词+单数可数名词+that从句such+形容词+复数可数名词/不可数名词+that从句so+形容词+a/an+单数可数名词+that从句HespokesofastthatIcouldn'tfollowhim.他讲得太快,我跟不上。Hetoldussuchfunnystoriesthatwealllaughed.他给我们讲了那么多有趣的故事,我们全都哈哈大笑。2.考例:1)这山太高,我们很难到达山顶。(四川)Thismountainis______thatwecan_________thetop.sohighnotreach2)MissGaoaskedaquestion,butitwas______thatnobodycouldanswerit.A.verydifficultB.toodifficultC.difficultenoughD.sodifficultD五、对其它状语从句的考查还有五种状语从句:地点状语从句、原因状语从句、目的状语从句、方式状语从句、让步状语从句。1.要点:1)掌握常用的引导词:①引导地点状语从句的有:where(在哪里),wherever(无论何地),etc.如:Wherethereisawill,thereisaway.有志者,事竞成。Whereveryougo,Igotoo.无论你去哪里,我都去。②引导原因状语从句的有because,as,since,for。because常回答why引导的疑问句,该从句一般位于主句后;since比as正式,两者不回答why引导的问句,而且其从句一般放在句首。如:—Whycan'tIgo?为什么我不能去?—Becauseyou'retooyoung.因为你年纪太小了。As(Since)youarenotfeelingwell,you'dbetterstayathome.既然你不太舒服,还是留在家里的好。③引导目的状语从句的有sothat(以便)等。如我给他包了一点食物,让他不致挨饿。Ipackedhimalittlefoodsothathewouldn'tbehungry.⑤引导让步状语从句的有though/although(虽然),eventhough(尽管),nomatterwho(无论谁),nomatterhow(无论怎样),nomatterwhat(无论什么)等。如:尽管这工作很辛苦,我还是很喜欢。Thoughit'shardwork,Ienjoyit.不管工作多么艰难,他都从不放弃Nomatterhowhardtheworkwas,henevergaveitup.2)because不能与并列连词so,though/although不能与but同时在句中使用。如Shewaslateforschoolbecauseshemissedthebus.=Shemissedthebus,soshewaslateforschool.It'snotcheap,butit'sverygood.=Thoughit'snotcheap,it'sverygood.2.考例:1)Ican'tunderstandthispassage_____therearenonewwordsinit.(安徽)A.ifB.becauseC.thoughD.and2)“WhydidLiLeiuseapencil?”“_____hispenwasbroken.”(福州市)A.BecauseB.WhenC.UntilD.IfCA六、对状语从句和宾语从句、简单句、并列句的混合考查【考点1】区分when,if引导宾语从句和状语从句的不同:when引导时间状语从句意为“当……时候”,引导宾语从句意为“什么时候”;if引导条件状语从句意为“如果”,引导宾语从句意为“是否”。如:1.—Mikewantstoknowif_____apicnictomorrow.—Yes.Butifit_____,we'llvisitthemuseuminstead.(河北)A.youhave;willrainB.youwillhave;willrainC.youwillhave;rainsD.willyouhave;rainsC2.—Doyouknowwhenhe_____backtomorrow?—Sorry,Idon't.Whenhe_____back,I'lltellyou.(安徽)A.comes;comesB.comes;willcomeC.willcome;comesD.willcome;willcomeC【考点2】状语从句和宾语从句、状语从句和简单句、并列句的同义转换。如:1.A:Heistooyoungtogotoschool.B:Heis_____young_____hecan'tgotoschool.(四川)2.A:Tomisthetallestinhisclass.B:Tomis_______anyotherstudentinhisclass.(四川)3.A:Theboxissolight______theboycancarryit.B:Theboxislightfortheboytocarry.(南京)tallerthanenough4.A:Putonyourcoat,oryou'llcatchacold.B:__you_____putonyourcoat,you'llcatchacold.(上海)Ifdon’t宾语从句与中考试题在复合句中用作宾语的从句叫做宾语从句。宾语从句是初中英语中最重要的一种从句,它内容完整,句型结构较为复杂,主句和从句时态搭配要求严格,在中考试题中频频出现。而且学好宾语从句也可为到高中学习间接引语、主语从句、表语从句及同位语从句打下
