高考英语状语从句易错考点分析课时教案一、误用not…unti…句式“MayIgoandplaywithDickthisafternoon,Mum?”“No,youcan’tgoout______yourworkisbeingdone.”A.beforeB.untilC.asD.themoment【陷阱】容易误选B,误认为这是考查not…until…结构。【分析】最佳答案选C。句中的yourworkisbeingdone表明“你正在做作业”,选as表原因。二、混淆as与while的区别“I’mgoingtothepostoffice.”“_______you’rethere,canyougetmesomestamps?”A.AsB.WhileC.BecauseD.If【陷阱】容易误选A。【分析】最佳答案选B。尽管as和while均可用作从属连词引导时间状语从句,表示“当……的时候”,但两者有一个重要区别,就是这样用的as从句的谓语不能是状态动词。当然,如果as不是表示“当……的时候”,其谓语是完全可以用状态动词的。如:Iwenttobedearly,asIwasexhausted.我很累了,所以很早就上床睡了。(此句中的as表示原因,意为“因为”、“由于”)请做以下两题,答案均选while,不选as:(1)_______youareathomealone,pleasedon’tleavethedooropen.A.WhileB.AsC.BeforeD.How(2)_______youarealonewithher,tellherthatyoulikeher.A.WhileB.AsC.AfterD.How三、忽略where引导地点状语从句Thevisitoraskedtohavehispicturetaken_______stoodthefamoustower.A.thatB.atwhichC.whenD.where【陷阱】几个干扰项均有可能误选。【分析】最佳答案选D。where表示“在……的地方”,用以引导地点状语从句。注意,此题还涉及倒装,即此句的主语是thefamoustower,谓语是stood,正常词序为wherethefamoustowerstood,使用倒装是为了保持句子平衡,避免头重脚轻(fromwww.nmet168.com)。四、忽略状语从句省略句“ShallMarycomeandplaycomputergames?”“No,_______shehasfinishedherhomework.”A.whenB.sinceC.unlessD.assoonas【陷阱】几个干扰项均有可能误选。【分析】最佳答案选C。此句为省略句,答句句首的No表明其后省略的是一个否定句,全句补充完整为:Shecan’tplaycomputergamesunlessshehasfinishedherhomework.请做类似试题(答案均选B):(1)“Wouldyoumindmysittingherewithyou?”“No,______youaren’ttoonoisy.”A.whenB.ifC.unlessD.assoonas(2)“Willheagreetocometojoinusinthework?”“No,_______wepromisehimmoremoney.”A.whenB.unlessC.unlessD.assoonas(3)“Canyoufinishtheworkintime?”“No,_______wedon’tsleepthroughoutthenight.”五、注意themoment用作连词“Whendidheleavetheclassroom?”“Heleft______youturnedbacktowriteontheblackboard.”A.thetimeB.themomentC.untilD.since【陷阱】几个干扰项均有可能误选。【分析】最佳答案选B。themoment用作连词,意为“一……就……”,相当于assoonas。类似地,theminute,theinstant也可用作连词,表示“一……就……”的意思。如以下试题也选B:(1)“DidyouremembertogiveMarythemoneyyouowedher?”“Yes,Igaveittoher________Isawher.”A.whileB.themomentC.suddenlyD.until(2)Thedoorkeepergavethealarm_______hesawthesmoke.A.whileB.theinstantC.suddenlyD.before(3)Iraisedthealarm_______Isawthesmoke.A.whileB.theminuteC.suddenlyD.since
