专题句型状语从句,考点揭密中考考点设置典型例题解析课时训练,考点揭密,在复合句中修饰主句中的动词、形容词或副词或句子，起状语作用的从句。

由从属连词引导，从属连词在从句中不充当句子成分。

状语从句可置主语之前，也可置主语之后。

前置时，从句后用逗号与主句分开；后置时，与主句之间无标点符号。

状语从句可分为时间、原因、目的、结果、条件、比较、地点、让步、方式等九类。

e.g.Ifyougototheparty,youwillhaveagoodtime.e.g.YouwillhaveagoodtimeIfyougototheparty.,中考考点设置,1.时间状语从句

（1）引导词：

when,while,as,before,after,assoonas,until/till,since.,e.g.MotherwascookingdinnerwhenIreachedhome.（when“当的时候”）,e.g.Whilethegirlwasshopping,theUFOlanded.（While“当的时候”）,e.g.Dontclosethewindowbeforeyougotobed.（before在之前）,e.g.Ashewasreading,hewaslisteningtotheradio.（As“一边一边”）,e.g.AfterIhaddonemyhomework,Iwenttobed.,e.g.TheGreenshaslivedheresincetheycametoChina.（since引导的时间壮语从句若用一般过去时，主句则用现在完成时,时间壮语从句中若用一般将来时，从句则用一般现在时表示将来，即遵循“主将从现”的原则。

e.g.IwillwritetoyouassoonasIgettoBeijing.,e.g.Iwilltellhimwhenhecomesback.,注意,e.g.IwontgotobeduntilIfinishmyhomework.,（3）not.until的同义句替换。

notuntil在否定句中表示“直到才”，主句中的动词常用终止性动词,这时till/until可用before替换,till/until在肯定句中表示“直到为止”主句中动词用延续性动词e.g.Iwaitedtill/untilhearrived.（wait是一个延续性动词）,e.g.Ididntleaveuntil/till/beforeshecameback.（leave是个短暂性动词）,practice:

1.IwillgotobedassoonasI_myhomework.A.willfinishB.finishingC.finish,C,4.IwillnotwatchTVuntilIfinishmyhomework.=IwillnotwatchTV_IfinishMyhomework.,before,2.Mysister_（read）herbookintheclassroomwhenherteachercamein.,wasreading,3.Imy_（do）homeworkwhilemyparents_（watch）TVlastnight.,wasdoing,werewatching,（3）if.not与unless（=ifnot）及or的同义句转换。

（2）遵循“主将从现”的原则,（即主句若为一般将来时，从句用一般现在时代替将来。

）,2.条件状语从句

（1）引导词：

if,unless.,e.g.IfIamfree,Iwillcallyou.,e.g.Ifitdoesntrain,wewillgoforawalk.,unless是从属连词，它引导条件壮语从句，译作“除非否则的话”,e.g.Youwillbelateforclassunlessyoustartrightnow.除非你现在出发否则的话年上学就会迟到的。

e.g.Youwillnotsucceedunlessyouworkhard.,小结:

“祈使句+or+一般将来时的陈述句”结构中，Or表示转折，译作“否则，不然的话”相当于一个否定的条件状语从句。

相当于Ifyoudont（cant）,youwill,例句.Studyharder,oryouwillfailtheexam.=Ifyoudontstudyharder,youwillfailtheexam.=Unlessyoustudyharder,youwillfailtheexam.,例句.Hurryup,oryouwillbelate.=Ifyoudonthurryup,youwillbelate.=Unlessyouhurryup,youwillbelate.,practice:

1.Ifyou_totheparty,you_haveagoodtime.,go,will,2.She_nextSundayifshe_busy.,willgoshopping,wontbe,3.Pleasehurryup,oryouwillmissthetrain.=_you_hurryup,youwill_thetrain.=_youhurryup,youwillmissthetrain.,4.WatertheyoungtreesasoftenasPossible,ortheywilldiesoon.=_you_watertheyoungtreesasoftenaspossible,theywilldiesoon.=_youwatertheyoungtreesasoftenaspossible,theywilldiesoon.,If,dont,Unless,If,dont,Unless,miss,中考考点设置,3.原因状语从句,

（1）引导词:

because,since,as.,

（2）对because原因状语提问用“why”。

（3）because不能与so连用。

（4）because,since，as,for的区别：

Whyareyoustandinghere?

-BecauseImwaitingformyuncle.,because从句所表示的是对方不知道的直接的原因，因此在回答以why引导的特殊疑问句时只可用because,它引导的从句可以位于主句前或主句后.而as,since引导的从句却不可；,例句:

LiHongdidntgotoschoolyesterday,becausehewasill.,as从句所表示比较明显的原因和理由（由于,既然）这种原因一般是大家知道的,一般从句说明原因，主句说明结果。

其从句位于主句之前,since用来表示比较勉强的理由和原或原由已为人们所知。

e.g.Asthewaterwasnotdeep,wewereabletocrosstheriver.（从句说明原因，主句说明结果）,e.g.ASIknewhewasill,Ididntcallhim.,e.g.Sinceeverybodyishere,letsbiginthemeeting（“大家都在这里”的原由已为人们所知）,e.g.Sinceyoucantanswerthequestion,（原由已为人们所知）Illasksomeoneelse.,for往往用于附加理由证明。

所说的理由是一种补充说明。

分句前常有逗号，其引导的分句不可放于句首。
