状语从句的省略与非谓语动词在英语学习过程中,我们经常遇到状语从句中的省略用法,它是一种简洁、精练、地道的文字表达形式,也是值得关注的一个高考考点。状语从句的省略规则如果主句和从句的主语一致,且谓语包含系动词be的某种形式,那么可以将从句的主语及动词be省略。省略结构中非谓语的使用是高考的热点。一、when,while,until引导的时间状语从句【经典例句】1.When(itis)takenaccordingtothedirections,thedrughasfewersideeffects.2.Dobecarefulwhen(youare)crossingthestreet.3.Don’tcomeinuntil(youare)askedto.【高考链接】1.(2013浙江卷)Therearesomehealthproblemsthat,when______intime,canbecomebiggeroneslateron.A.nottreatedB.notbeingtreatedC.nottobetreatedD.nothavebeentreated2.(2013福建卷)Anyone,once____positiveforH7N9fluvirus,willreceivefreemedicaltreatmentfromourgovernment.A.tobetestedB.beingtestedC.testedD.totest3.(2012安徽卷)When____forhisviewsabouthisteachingjob,Philipsaidhefounditveryinterestingandrewarding.A.askingB.askedC.havingaskedD.tobeasked4.(12全国I)Filmhasamuchshorterhistory,especiallywhen_______suchartformsasmusicandpainting.A.havingcomparedtoB.comparingtoC.comparetoD.comparedto5.(06浙江)When______differentcultures,weoftenpayattentiononlytothedifferenceswithoutnoticingthemanysimilarities.A.comparedB.beingcomparedC.comparingD.havingcompared6.(2004全国IV)Itshamesmetosayit,butItoldaliewhen____atthemeetingbymyboss.A.questioningB.havingquestioningC.questionedD.tobequestioned7.(2004全国II)Whenfirst______tothemarket,theseproductsenjoyedgreatsuccess.A.introducingB.introducedC.introduceD.beingintroduced二、if,unless,once引导的条件状语从句。【经典例句】1.If(itis)properlytreated,wastewilldonoharmtotheenvironment.2.I’llnotgotothepartyunless(Iam)invited.3.Once(youare)caughtstealinginasupermarket,youwillbepunished.1.(13江西)If_____tolookafterluggageforsomeoneelse,informthepoliceatonce.A.askedB.toaskC.askingD.havingasked…,youinformthepoliceatonce=If(youare)askedtolookafter…【高考链接】2.(2009湖南)Everyeveningafterdinner,ifnot_____fromwork,Iwillspendsometimewalkingmydog.A.beingtiredB.tiringC.tiredD.tobetired3.(2007四川)Theflowershisfriendgavehimwilldieunless________everyday.A.wateredB.wateringC.waterD.towater三、though,although,evenif,eventhough,however等引导的让步状语从句。【经典例句】1.Evenif(Iam)invitedto,Iwon’tgotosuchabadlecture.2.Though/Although(hewas)blamedforhismistake,theboydidn'tseemtobeangry.【高考链接】1.(2010全国Ⅱ)Though______toseeus,theprofessorgaveusawarmwelcome.A.surprisingB.assurprisedC.surprisedDbeingsurprised2.(2006广东)Nomatterhowfrequently________,theworksofBeethovenstillattractpeopleallovertheworld.A.performedB.performingC.tobeperformedD.beingperformedEnjoyEnglishEnjoylife!
