状语从句重点难点素材

高三语法专题复习：定语从句名词性从句状语从句主从复合句theAdverbial状语修饰动词、形容词、副词或整个句子，说明动作或状态特征的句子成分，叫做状语。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。状语从句在句首时，往往有逗号使从句与主句隔开。状语从句通常由一个连词引起，也可以由一个起连词作用的词组引起。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。考核要求九种常用的状语从句时间状语从句地点状语从句原因状语从句条件状语从句让步状语从句结果状语从句目的状语从句方式状语从句比较状语从句状语从句有九种，时地原因条状补，目比结果方让步，连词引导各不同；主句通常前面走，连词引导紧随后，从句若在主前头，主从之间有个逗。IdentifythetypesoftheAdverbialClauses.1.WhileIwaswonderingatthis,ourschoolmastertookhisplace.()2.Wherethereisawill,thereisaway.()3.Nowthat/Sinceeverybodyishere,let’sbeginourmeeting.（）4.I’llspeakslowlysothatyoucanunderstandme.()5.Socleverwasheastudentthathewasabletoworkoutallthedifficultproblems.()6.Aslongasyoudon’tloseheart,you’llsucceed.()7.Tryashemight,hecouldnotfindajob.()8.Theoldladytreatstheboyasifhewerehisownson.()9.ThemoreIcandofortheclass,thehappierI’llbe.()时间地点原因目的结果条件让步方式比较状语从句类型从属连词时间状语从句when,whenever,while,as,before,after,since,till,until,not…until,thefirst/second…time,each/everytime,nexttime,themoment/instant/minute，assoonas,immediately,instantly,directly,nosooner…than,hardly…when地点状语从句where,wherever,everywhere,anywhere原因状语从句because,as,since,seeing(that),giventhat,nowthat,inthat结果状语从句sothat,so…that,such…that条件状语从句if，unless，aslongas,suppose，supposing，incase，sofaras，provided/providing(that),onconditionthat目的状语从句so，sothat，inorderthat，forfearthat，lest让步状语从句although,though,疑问词+ever,nomatter+疑问词,evenif/though,whether…or,while(置于句首，表“虽然，尽管”）方式状语从句as，asif，asthough比较状语从句as…as，notas/so…as，than,the+比较级...the+比较级•1状语从句连词的含义及用法比较；•2、nomatterwh-与wh-ever引导的从句的区别；•3、状语从句的时态问题；•4、状语从句倒装及省略问题；•5、状语从句与其它从句区别。WhenIlivedthere,IusedtogototheseashoreonSundays.TheplanehadalreadytakenoffwhenIgottotheairport.Whenyouhavefinishedyourwork,youmayhavearest.总结：when的用法1Whenhewasayoungman,hewasfondofhunting.Asayoungman,hewasfondofhunting.总结：when的用法2时间状语从句问题1:1.(04北京春)Wewereswimminginthelake______suddenlythestormstarted.A.whenB.whileC.untilD.before2.(02上海)Hewasabouttotellmethesecret______someonepattedhimontheshoulder.A.asB.untilC.whileD.when3.(05上海)Hetransplantedthelittletreetothegarden______itwasthebesttimeforit.A.whereB.whenC.thatD.until4.(05福建)－DidJackcomebackearlylastnight?－Yes.Itwasnotyeteighto’clock____hearrivedhome.A.BeforeB.whenC.thatD.until5.(06辽宁)Hewasabouthalfwaythroughhismeal______afamiliarvoicecametohisears.A.whyB.whereC.whenD.whileADBBC连接词when的用法小结1.when可用来引导时间状语从句，意为“当……的时候”从句的谓语动词可以是延续的，也可以是短暂的。如：Whenthefilmended,theywentback.WhenIlivedthere,IusedtogototheseashoreonSundays.2.When常用于下列句式：意为“就在那时/这时,突然...”，相当于andthis/thattime,表示一种没有预料到的新情况出现如：wasdoingsomething…whenwasabouttodo…whenwasonthepointofdoingsth...when…haddone…when注意同一个从属连词的多义性：连接词when的用法小结3.when可以表“既然,考虑到”(consideringthat)，如：HowcanIhelpthemtounderstandwhentheywon’tlistentome?4.when可以表条件，意为“倘若，如果”(if)，如：HowcanIgetajobwhenIcan'tevenreadorwrite?5.when可以表转折，意为“虽然，然而，可是”(although)，如：Heclaimedtobe18whenIknowshe'sonly16.问题2:6.(06天津)ThecostoflivinginGlasgowisamongthelowestinBritain,______thequalityoflifeisprobablyoneofthehighest.A.sinceB.whenC.asD.while7.(04年江苏)______Iacceptthatheisnotperfect,Idoactuallyliketheperson.A.WhileB.SinceC.BeforeD.Unless8.________itistruethatastudent’smostimportantgoalistodowellinhisorherstudies,itdoesn’tneedtobetheonlygoal.AwhenBAsCWhileDBefore25.Marymadecoffeeherguestswerefinishingtheirmeal.(全国)A.sothatB.althoughC.whileD.asifDACC1.while可用来引导时间状语，意为“当……的时候”；引导的动作必须是延续性，侧重主句与从句的动作相对比。如：Pleasedon’ttalksoloudwhileothersareworking.2.while作为并列连词，意为“而，却”，表示对比。JanewasdressedinbrownwhileMarywasdressedinblue.3.while也可用来引导让步状语，置于句首，意为“尽管，虽然”，相当于although。WhileIadmitthattheproblemsaredifficult,Idon’tagreethattheycan’tbesolved.4有“趁…的情况赶紧做,否则来不及了”的意思。Strikewhiletheironishot.连接词while的用法小结1.as可用来引导时间状语，意为“一边…一边”；“随着”。如：Shesangasshewalkedhomealltheway.Shewasdoingherhomeworkasshewaslisteningtothemusic.Asshegrewolder,shebecamemorebeautiful.2.as也可用来引导原因状语从句意为“因为”。如：Assheisfreetoday,shewouldliketodosomeshopping.3.as还可用来引导让步状语从句（通常用倒装结构）意为“尽管”。如：Hardasheworked,hecan’tworkouttheproblem.Childasheis,heknowsalot.连接词as的用法小结as引导让步状语从句的基本结构：形容词/副词/分词/不带冠词的名词/动词原形+as/though+主语+谓语(助动词/情态动词)Proundas/thoughheis,he'safraidtoseeme.Tryashemight,hecouldn'tmanageit.Fastasyouread,youcan'tfinishit.Boyasheis,heknowsalotabouttheworld.连接词when,while,as的用法区别：when,while,as这三个连词都可表示“当……的时候”，使用时应注意：1、when可表示一个时间点，也可表示一个时间段。如：Whenhecamein,wewerehavingsupper.Whenwewerehavingsupper,thelightsuddenlywentout.2、while则只表示一个时间段。它所引导的时间状语从句中常用进行时态。如：When/Whilehewaseatinghisbreakfast,heheardthedoorbellring.WhilehewaswatchingTV,theboyfellasleep.3、as则强调主句和从句的动作在同一时间进行;也可表示“随着……”，。Shesangasshewalkedalong.Astheelectionapproached,theviolencegotworse.问题3:1.(01北京春)－DidyouremembertogiveMarythemoneyyouowedher?－Yes.Igaveittoher______Isawher.A.whileB.themomentC.suddenlyD.although2.(1998上海)Ithoughtherniceandhonest______Imether.A.firsttimeB.forthefirsttimeC.thefirsttimeD.bythefirsttime3.______enteredtheofficewhenherealizedthathehadforgottenhisreport.A.HehardlyhadB.HadhehardlyC.HardlyhadheD.HardlyhehadBCC小结：1．一些词如:themoment,theminute,theinstant,immediately,dir
