状语从句（2h）教学目标：掌握9大状语从句及其中重要的引导词与句型。由于高考中状语从句经常和从句的时态语态，动词短语的搭配，以及状语从句的省略，虚拟语气与倒装一起考查。因此必须掌握好：1时间状语从句中各种引导词引导的主句与从句的时态的判断2地点状语从句中表示抽象含义时从句必须在主句之前3原因状语从句中because，as，nowthat的位置问题4目的状语从句中的sothat与在结果状语从句中的区分5结果状语从句中的so/such…that…的特殊结构及其倒装6条件状语从句中的if，unless的用法7方式状语从句中的虚拟语气的用法8让步状语从句中的as,though做引导词时的倒装用法教学重点：1掌握常用的状语从句中的引导词2判断状语从句中的时态3状语从句中的倒装情况：nosooner…than,hardly/scarcely…when,not…until用于句首时的倒装；结果状语从句中so/such置于句首时的倒装情况；as/though引导的让步状语从句的倒装情况4asif/though引导的方式状语从句中的虚拟语气教学进程：导入：状语从句在句子中作状语，修饰谓语。㈠时间状语从句⒈回顾有哪些词可以引导时间状语从句—when,while,as表示“当…时”;immediately,instantly,assoonas,directly,themoment,nosoonerthan,hardlywhen,scarcelywhen,once表示“一…就…”；till,until,notuntil表示“直到…才”；before表示“还没来得及…就…”，“不到…就…”；since表示“自从…”；everytime,eachtime,nexttime,thefirsttime,anytime,allthetime表示“每当…”，“每次…”，“下次…”等等⒉状语从句中的时态的判断方法：⑴过去，现在，将来⑵延续性与非延续性/时间点与时间段⑶主从句中的谓语动词的先后关系⑷判断开始时间与截止时间⒊when,while,as都可以表示主从句动作同时进行(口头造句举例)如：whenthemusicfadesaway,peopletideaway.Shesattherealonewhileotherswerealldancing.Hedancesjoyfullyasthemusicgoes.当主句动词为短暂性，从句动词用延续性动词的进行时态表示一段时间内的动作时，三个词可互换。如上面的第二个句子。When可引导持续动作亦可引导短暂动作。如WhenIwasyoung,IusedtoplayBarbiedolls.While引导的必须为延续性动词，侧重和主句中的动词相对比。如Whilehewasmakingthebreakfast,hiswifewassleeping.As可以指主从句的动作交替进行。如Shefeelssomeone’sfollowingher,soshewalkedfastaslotokedback.⒋“一…就…”⑴Themomentsheheardthemusicshelikedmost,shestooduptodance.⑵HardlyhadtheCinderellagothomewhentheclockknocked12o’clock.⑶AssoonasIgetthere,I’llletyouknow.(强调当nosoonerthan和hardlywhen,scarcelywhen提到句首时要用到倒装)⒌till,until,not…until⑴肯定句：主谓语必须为延续性动词Youcandancetoyourjoyuntilyoufeeltired.⑵否定句：主从句必须为非延续性动词Youcan’tmarryhimuntilIsayyes.（强调till不能放句首，until可以）6.before⑴Ihadn’tfinishedmysentencebeforeheturnedhisbacktome。⑵Itwillbe2yearsbeforeIgetback.7.sinceIhaven’tspokentohimsince1yearago.Itis3yearssinceIsmoked.Ithasbeen3yearssinceIsmoked.8．Everytime…歌词：everytimeIleavetoheadoutontheroad,Iwannatakeyouwithme,savemefromthecold.练习：1Weusuallycallsomeoneagreenhand____(当他没有经验)hisjob.(experienced)2IwasspeakingtoAnnonthephone___（突然我们短线了)(cut)㈡地点状语从句表示抽象含义时，从句需在主句前。如Wheretherearegirls,thereisgossip.where引导的定语从句与状语从句You’dbettermakeamarkwhereyouhaveanyquestions.（状从）You’dbettermakeamarkattheplacewhereyouhaveanyquestions.(定从)㈢原因状语从句回顾有哪些引导词—because,since,as,nowthat,seeingthat,consideringthat,owingto,becauseof,thanksto,dueto,for区别/连词位置内涵语气能否回答why能否被强调Because主句前或后直接因果关系强能能As主句前或后双方都知道的原因弱不能不能Since/nowthat主句前When有时也表示原因。如Itissillyofyoutotakehiswordswheneveryonetellsyouhe’saliar.㈣目的状语从句Sothat,inorderthat,forfearthat,incase,lest等Shelookedattheclocknowandthen,forfearthatshemightgethomelate.Hehasmadeupawholestoryincasesheasks.㈤结果状语从句So+形容词/副词+that从句So+形容词+a/an+可数名词单数+that从句So+many/much/few/little+名词+that从句Itissoeasythatevenafive-year-oldstudentcanworkitout.Such+a/an+形容词+可数名词单数+that从句Such+形容词+可数名词复数/不可数名词+that从句Such+alotof/lotsof+名词+that从句Heissuchastrangegirlthatnooneliketotalktoher.So或such置于句首倒装Sopooragirlsheisthatshehasnofreedomatall.Too…to与notenough…to与so…asto…㈥条件状语从句As/solongas,if,unless,incase(与目的状语从句中意义不同),supposing,providedthatIncase—Incasethereisafire,whatwillusdofirst?Shealwaysdressherselfwellincasehecometoseeher.㈦方式状语从句As,asif,asthoughAsif/though引导的从句如果很难实现或与事实相反，应用虚拟语气。如Don’tlookatmelikethatasifIhaddonesomethingwrong.㈧让步状语从句Although,though,可与yet,still或nevertheless连用，不能和but连用。Eventhough,evenif有时需要用虚拟语气。如EvenifIwerebusy,Iwouldgo.Though有时可以用于句末，指“然而“Hesaidhewouldcome,hedidn’t,though.As与though引导的从句用于主句之前时应使用虚拟语气。表语是单数名词时，前置时还应省略冠词Childasmyson,heknowsalot.MuchasIlikeit,Iwon’tbuyit.Whether…or…,wh+ever,nomatterwh+everWhetheryoubelieveitornot,it’strue.㈨比较状语从句As…as…,notas/so…as,morethan…,themore…in/of,A…timesas…asB课堂练习：I.填入适当的引导词1.Ihaven'theardfromhim_____hewenttoAmerica.2.Hewon'tbehere_____heisinvited.3.Hewillnotgotothecinema_____heisverybusy.4.Wefoundthekey_____sheladleftit.5.Wefoundthebookstwodays____hehadgoneaway.6.Wehadnosoonergottothestation_____thetrainleft.7.HespeaksEnglish______hewereanEnglishman.8.Heisexplainingclearly_______theycouldunderstand.9.Donotleavetheroom_____youhavefinishedthetest.10.Shesang______shewentalong.答案：1.since2.unless3.because4.where5.after6.than7.asif8.sothat9.before10.asII.改错1.Thechildrenwererunningontheplaygroundasfastastheycan.2.Sinceherhusbandhaddied,soshehadtosupportherfamily.3.Hewon'tgooutuntilhismotherwillcome.4.Hewasveryfoolishthathedidn'tpasssuchaneasyexam.5.Tomhadgoneoutassoonashismothergothome.6.Itwasthreemonthssincehecametoourschool.7.Theplaygroundofourschoolislargerthantheirschool.8.ThestreetsinNanjingarewiderthanShanghai.9.Whateverthereisplentyofsunandrain,thefieldsaregreen.10.Shesingssongsasifsheisabird.答案：1.can改为could2.去掉so3.willcome改为comes4.very改为so5.assoonas改为when6.was改为is7.than之后加上thatof8.than后加thosein9.whatever改为wherever10.is改为wereIII.找出从句并指出是那类从句1.Itdependsonwhetherwehaveenoughtime.2.Thequestionheaskedwaswheretheelectricalequipmentshouldbestored.3.Themountainisnolongerwhatitusedtobe.4.Thefactthatsheworkshardiswellknowntousall.5.Hewasnotthemanthathewasbefore.6.Nowyouwasfree,whynotgoswimmingwithus?7.Wherethereareschoolsandcolleges,thereareexamina
