专题六状语从句英语外研版◆时间状语从句的考查要点1．before引导的从句中不用否定式谓语。常用如下句型：Itwillbelongbefore...(得过好久才……)Itwillnotbelongbefore...(过不了多久就……)Itwaslongbefore...(过了好久才……)Itwasnotlongbefore...(过了不久就……)2．since后面所用动词不同，该动词所表示动作持续时间的计算方法也不同。since＋瞬间动词过去式从该动作发生时算起since＋持续性动词过去式从动作结束时算起Itistwoyearssincehejoinedthearmy.他参军两年了。Itistwoyearssincehesmoked.他戒烟两年了。3．as，when，while用法一览表。类别作用例句asas表示“当……的时候”，往往和when/while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。ShecameupasIwascooking.(同时)Therunnersstartedasthegunwentoff.(几乎同时)when(atorduringthetimethat)既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。Itwasrainingwhenwearrived.(指时间点)Whenwewereatschool，wewenttothelibraryeveryday.(在一段时间内)whilewhile意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示aperiodoftime时，两者可以互换。Pleasedon’ttalksoloudwhileothersareworking.Hefellasleepwhile/whenreading.Strikewhiletheironishot.(用as或when不可，这里的while意思是“趁……”)4.引导时间状语从句的连接词除上述外还有：(1)till，not...until...，untilDon’tgetoffthebusuntilithasstopped.Hewaitedforhisfatheruntil/tillitwastwelveo’clock.(2)hardly/scarcely...when，nosooner...than表示“刚……就”Wehadhardlygot/Hardlyhadwegotintothecountrywhenitbegantorain.Nosoonerhadhearrived/Hehadnosoonerarrivedthanshestartedcomplaining.(3)directly，immediately，themoment，theminute，theinstant，assoonas，意为“一……就”Hemadeforthedoordirectlyheheardtheknock.Themomenthesawhismother，heburstintotears.(4)eachtime，everytimeEachtimehecametomycity，hewouldcallonme.题组训练1用适当的连词填空1．Ifalotofpeoplesayafilmisnotgood，Iwon’tbothertoseeit，orI’llwaititcomesoutonDVD.2．Theyrushedinwewerediscussingproblems.3．OneFriday，wewerepackingtoleaveforaweekendawaymydaughterheardcriesforhelp.until/tillwhilewhen4．ItwasApril29,2001PrinceWilliamandKateMiddletonwalkedintothepalacehalloftheweddingceremony.5．Asisreported，itis100yearsQinghuaUniversitywasfounded.6．Hehadnosoonerfinishedhisspeechthestudentsstartedcheering.whensincethan◆让步状语从句的考查要点1．although与though可以引导让步状语从句，不能与but连用，但可以与yet连用。Although/Thoughtheyarepoor，(yet)theyarewarm­hearted.2．evenif或eventhough引导让步状语从句，表示“即使”、“纵然”，用来使人注意下文所强调内容的性质。I’llgetthereevenif/thoughIhavetosellmyhousetogetenoughmoneytogobyair.3．nomatter后接上who，what，where，how等疑问词引导让步状语从句，也可以在这类疑问词后面加上ever构成whoever，whatever，wherever，however等。但在引导名词性从句时只能用wh­ever类词。Don’ttrusthim，nomatterwhat/whateverhesays.Iwilleatwhateveryougiveme.Nomatterhowhardtheworkis，you’dbettertrytodoitwell.4．as也可以引导让步状语从句，需将从句中的表语、状语以及谓语中的实义动词提前至从句句首，引起倒装；作表语的单数可数名词前如有冠词，冠词需省去。though引导的从句也可以倒装，但although引导的不可以。Childas(though)heis，heknowsalot.MuchasIlikeit，Iwon’tbuy.Tryashewould，hecouldn’tlifttheheavybox.5．while也可以引导让步状语从句，表示“尽管”，比though/although语气弱。while引导的让步状语从句一般要位于句首。题组训练2用适当的连词填空1．Itwasanicemeal，alittleexpensive.2．volleyballishermainfocus，she’salsogreatatbasketball.3．FrankinsistedthathewasnotasleepIhadgreatdifficultyinwakinghimup.thoughWhile/Though/Althoughalthough/though4．regularexerciseisveryimportant，it’sneveragoodideatoexercisetooclosetobedtime.5．allofthemarestrongcandidates，onlyonewillbechosenforthepost.6．We’llmakeatriptheweatherisbad.Although/ThoughWhile/Though/Althoughevenif/though◆原因状语从句：because，for，as，since，nowthat1．表示不知道的原因时用because，即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。YouwanttoknowwhyI’mleaving？I’mleavingbecauseI’mfedupwiththeboss.for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。It’smorningnow，forthebirdsaresinging.(很显然，鸟叫不可能是“现在已是早上”的原因)。2．表示已经知道的原因时用as或since，即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前，但有时却相反。Seeingallofthechildrenalreadyseated，hesaid，“Sinceeveryoneishere，let’sstart.”3．下列情况下只能使用because：①在回答why的问句时；②在用于强调句型时；③被not所否定时。◆地点状语从句：where，wherever等Makeamarkwhereveryouhaveanyquestions.WewillgowherethePartydirectsus.◆目的状语从句：that，sothat，inorderthat注意：目的状语从句中的谓语动词常与情态动词连用，否则可能是结果状语从句，不可置于句首。Hegotupearlysothathecouldcatchtheearlytrain.◆结果状语从句：that，sothat，so...that...，such...that...注意：so＋形容词/副词＋that从句；such＋名词＋that从句。Sheissogoodthatwealllikeher.Heissuchagoodteacherthatweallrespecthim.◆方式状语从句：as，asif/thoughI’lldoasIamtoldto.Itlooksasifitisgoingtorain.◆条件状语从句：if，unless，so/aslongas，incase，once，onconditionthat等Youcanusemybikeaslongasyoureturnitontime.◆注意状语从句中从句的省略现象1．连词＋过去分词Don’tspeakuntilspokento.Unlessrepaired，thewashingmachineisnouse.2．连词＋现在分词Lookoutwhilecrossingthestreet.3．连词＋形容词/其他常见的有ifnecessary，ifpossible，whennecessary，ifany等。Ifnecessary，Iwillgothere.题组训练3用适当的连词填空1．Thepoliceofficersinourcityworkhardtherestofuscanliveasafelife.2．Sheworkedhardeverythingwouldbereadyintime.3．Hehadhiscamerareadyhesawsomethingthatwouldmakeagoodpicture.4．Jackwasn’tsayinganything，buttheteachersmiledathimhehaddonesomethingveryclever.5．thereisawill，thereisaway.inorderthat/sothatsothatincaseasif/asthoughWhere◆语法与写作用状语从句翻译下面的句子1．当有人落后的时候，其他人总是过来提供帮助。(2013·江西·书面表达)2．通常无论我们离得多远或多忙，我们都会尽量回家过节。(2013·辽宁·书面表达)Whensomefellbehind，otherswouldcomeandofferhelp.Usually，nomatterhowfarawayorhowbusyweare，wewilltrytoreturnhomeforthecelebration.3．尽管我很累，但我从没感到这样快乐过。(2013·陕西·书面表达)4．我告诉他长大后我会成为赢家。(2013·湖南·书面表达)5．首先，如果你接受我的道歉，我会非常高兴。(2013·山东·写作)TiredasIwas，Ineverfeltsohappy.Itoldh
