A.not;beforeB.dont;when C.notto;untilD.not;after考点一：when和while引导时间状语从句When和While的区别when是atorduringthetimethat,既指时间点,也可指一段时间,while是duringthetimethat,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词。when说明从句的动作和主句的动作可以是同时,也可以是先后发生；while则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时；如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如：a.Whentheteachercamein,weweretalking.当此句改变主从句的位置时,则为：Whileweweretalking,theteachercamein.b.Theyweresingingwhileweweredancing.when和while还可作并列连词.when表示“在那时”；while表示“而,却”,表对照关系.如：Thechildrenwererunningtomovethebagofricewhentheyheardthesoundofamotorbike.孩子们正要跑过去搬开那袋米,这时他们听到了摩托车的声音。Heisstrong_hisbrotherisweak.他长得很结实,而他弟弟却很瘦弱。巩固练习：用when或者while填空1) _Margowastalkingonthephone,hersisterwalkedin.2) _wevisitedtheschool,thechildrenwereplayinggames.3)_Sarahwasatthebarbers,Iwasgoingtoclass.4) _IsawCarlos,hewaswearingagreenshirt.5) _Allenwascleaninghisroom,thephonerang.6) _Ritaboughthernewdog;itwaswearingalittlecoat.7) Hewasdrivingalong_suddenlyawomanappeared.8) _Jakewaswaitingatthedoor,anoldwomancalledtohim.9)Hewasreadingabook_suddenlythetelephonerang.10) _itbegantorain,theywereplayingchess.巩固练习：用所给动词适当形式填空1) WhileJake_(look)forcustomers,he_(see)awoman.2)They_(play)footballontheplaygroundwhenit_(begin)torain.3) Astrangebox_(arrive)whilewe_(talk).4)John_(sleep)whensomeone_(steal)hiscar.5)Father_still(sleep)whenI(get)upyesterdaymorning.6)Grandma (cook)breakfastwhileI_(wash)myfacethismorning.7)Mother (sweep)thefloorwhenI(leave)home.8)I_(read)ahistorybookwhensomeone(knock)atthedoor.考点二：在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到时”，谓语动词只能用延续性动词。Theyoungmanreadtillthelightwentout.如果主句用否定式，其含义是“直到才”,“在以前不”,谓语动词可用瞬间动词。Dontgetoffuntilthebusstops.注意：till一般不用于句首。考点三：since引导的时间状语从句“主句用完成时，从句一般过去时”1)Howtimeflies！Threeyears_sinceI_youlasttime.(2014，龙东) A.havepassed；met B.haspassed；met C.passed；havemet D.haspassed；havemet2) Myunclehasbeentaughtinthisschool_hewastwentyyearsold.(鞍山) A.since B.for C.until D.after2.条件状语从句考点一：条件状语从句通常由if,unless引导。(unless=if.not)条件状语从句中if遵循三个原则：主将从现，主情从现，主祈从现1) Whatshallwedoifit_(snow)tomorrow?2) DontleavethebuildingunlessI_(tell)youto.3)Ithinkhewillgowithusifhe_free.

Sincewehavenomoney,wecantbuyit.考点二：because和so不能同用在一个句子里。1) Iwaslateforclassyesterday_therewassomethingwrongwithmybike.
