状语从句,状语从句考点1、各种从属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、状语从句的倒装问题；5、状语从句与其它从句的区别。,1、时间状语从句问题1：Dontbeafraidofaskingforhelp_itisneeded.（03全国卷）AunlessBsinceCalthoughDwhen,D,复习when时要注意比较它与while与as的区别。,when,while,as三者的具体用法关键在于动作发生的时间及从句的动词。while表时间，从句需用延续性动词，不用瞬间动词；when表时间，从句既可用延续性动词，又可以用瞬间动词；as表时间，与when相似，但侧重强调主、从句动作同点或同段进行，可用延续行动词的一般过去式表式过去进行时。(一边一边;随着)when,while后还可以接分词短语。,when作并列连词，表示一个动作在发生时，另一个动作接着发生，这时就不能用while、as。Iwaswalkingonthestreetwhensuddenlysomeonepattedmeontheshoulder.while作并列连词，表示两种情况对比。HewasplayingtheguitarwhilehissisterwaswatchingTV.,问题2：1)Washisfatherverystrictwithhimwhenhewasatschool?Yes.Hehadneverpraisedhimhebecameoneofthetopstudentsinhisgrade.（03北京春季）AafterBunlessCuntilDWhen2)Simonthoughthiscomputerwasbroken_hislittlebrotherpointedoutthathehadforgottentoturniton.（05北京春季）A.untilB.unlessC.afterD.because,C,A,until/till“直到止”(肯定句，主句是延续性动词);notuntil“直到才”(否定句，主句是终止性动词);until可用于倒装句和强调句，till不用于句首。NotuntilIreturneddidshefinishherhomework.ItwasnotuntilIreturnedhomethatshefinishedherhomework.,问题3：1、TheAmericanCivilWarlastedfouryears_theNorthwonintheend.(05广东卷)A.afterB.beforeC.whenD.then2、Hemadeamistake,butthenhecorrectedthesituation_itgotworse.（03北京）A.untilB.whenC.beforeD.as,B,C,before从句是高考中的一大热点，从时间概念上不难作出判断。,before与高考Someonecalledmeupinthemiddleofthenight,buttheyhungup_Icouldanswerthephone.A.beforeB.sinceC.untilDas,A,1.表示”在之前”.这时主句和从句两个动作按时间先后依次发生Wheredidyoustudybeforeyoujoinedthearmy?,2.表示“才”强调从句的动作发生得晚或慢Hehadwalkedforawholedaybeforehefoundwater.,3.表示“还没来得及就”强调在从句动作发生之前,主句动作已发生.HefellasleepbeforeIcouldtakeoffhisclothes.注意：这时before本身含有否定意义，从句不能再用否定句,Thestudentsrushedoutoftheclassroombeforethebellrang.,翻译：铃还没响，学生们就冲出了教室,5.表示“不知不觉地就”常用于句型beforeoneknewit.TimepassedquicklyandthreemonthswentbybeforeAqiaoknewit.,4.表示“趁着没”“以免”Wewanttobuysomethingnowbeforepricesgoup.,6.用在“Itwas/willbe(not)+一段时间before从句”中，译作“才”“就”(1)ItwasnotlongbeforeheleftfortheUnitedStates.(2)Itwasthreeweeksbeforetheyarrivedatthemountainvillage.(3)Itwillbefouryearsbeforewemeetagain.,时间状语从句的连词1.once,assoonas(immediately,directly,instantly,theminute/moment/instant)hardly/scarcelywhen,nosoonerthan2.every/eachtime,nexttime,thefirst/second/lasttimebythetime3.When/whenever#WhenIcamein,somestudentsweresleeping.Wheneveryouareintrouble,Illhelpyou.,1._Imethim,hewasdressedverywell.2.WesawanEnglishfilm_lastnight.3.Thisis_thatwehaveseenthefamousstar.,Thefirsttime,forthefirsttime,thefirsttime,Since(conj./prep./adv.)1.IhaventheardfromhimsinceIleftschool.2.Wehavelivedheresince2003/tenyearsago.3.Theyhaveneverseeniteversince.It+be+sometime+since-clause这个句型表示从since从句谓语动作发生以后到现在或过去所经过的一段时间，意为“自从.以来已多久了”Itis+sometimesince(did)Ithasbeen+sometimesince.(did)Itwas+sometimesince(haddone)1.ItistenyearssinceIlefthere.2.Itisthreeyearssincehisfatherpassedaway.。,Ileftschooltenyearsago.Ihaveleftschoolsincetenyearsago.3.Ihaveleftschoolfortenyearsago.4.ItistenyearssinceIleftschool.,5.Wehavelivedherefortenyears.6.Itistenyearssincewelivedhere.Wehaventlivedherefortenyears.短暂动词表示动作开始;延续动词表示动作结束,问题4：DidyouremembertogiveMarythemoneyyouowedher?Yes,Igaveittoher_Isawher.（01北京春季）AwhileBthemomentCsuddenlyDonce,B,地点状语从句-where/wherever,例题Makeamark_youhaveaquestion.A.inwhichB.thereC.whereD.that,Makeamarkinaplacewhereyouhaveaquestion.,C,TranslatingIfoundmybookswhereIhadleftthem.Youcangowhereveryoulike.Wherethereisawill,thereisaway.Whereveryougo,youwontbewelcome.Wherethereisplentyofsunandrain,thefieldsaregreen.,Ex.1.Youshouldputyourbook_itbelongs.A.towhichB.towhereC.whereD.which,2.Youngpeopleshouldgo_.A.wheremostlyneededB.inwhichmostneededC.wheremostneededD.wheretheymostneeded,C,C,III.原因状语从句,-Whywashepunished?-_.A.ItwassincehebrokethelawB.Itwasbecausehebrokethelaw.C.Itwasashebrokethelaw.D.Itwasthathebrokethelaw.,because;as;since-(now)that/seeingthatSinceyoudontfeelwell,youmaystayathomeaswell.Asheishonestanddiligent,everyonelikeshim.,forconj.并列连词Thegroundisverywet,foritrainedlastnight.Thedayhasbroken,forsomebirdsaresinging.,条件状语从句问题1：1、TheWTOcannotliveuptoitsname_itdoesnotincludeacountrythatishometoonefifthofmankind.（2000全国）AaslongasB.WhileCifDeventhough2、Itisknowntoallthat_youexerciseregularly,youwontkeepgoodhealth.（05重庆卷）A.unlessB.wheneverC.althoughD.if,C,A,问题2：1、_Icansee,thereisonlyonepossiblewaytokeepawayfromthedanger.（04北京春季）A.AslongasB.AsfarasC.JustasD.Evenif2、IalwaystakesomethingtoreadwhenIgotothedoctors_Ihavetowait.（05全国卷3）AincaseBsothatCinorderDasif,B,A,aslongas与asfaras都可引导条件状语从句，aslongas表示“只要”，asfaras表示“就而论（而言）”。题1根据题意应该选用B。incase表示“以防”，根据题2的句意，不难作出选择。,条件状语从句：if,unless,(ifnot.)aslongas/solongasonconditionthat只要as/sofaras“就而论（而言）”incase万一suppose/supposingprovided/providingthat假定假使,Translating1.Aslongasyouarehappy,itdoesntmatterwhatyoudo.2.IncaseIforget,pleaseremindmeaboutit.3.SupposeIseehim,whatshallItellhim?4.UnlessImmistaken,Iveseenthatmanbefore.5.Ifitweretorain,wewouldntgothere.6.Ifgivenanotherchance,hestillkepttalking.7.Ifpossible,handinyourhomeworkbeforeMonday.,让步状语从句,问题1：1、_Iacceptthatheisnotperfect,Idoactuallyliketheperson.（04江苏）A.WhileB.SinceC.BeforeD.Unless2
