Don’tleavethebuildingunlessItellyouto.(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：I’llhelpyouwithyourEnglishifamfreetomorrow.Hewon’tbelateunlessheisill.(3)“祈使句+and(or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。例如：Hurryup,oryou’llbelate.=Ifyoudon’thurryup,you’llbelate.Studyhardandyouwillpasstheexam.=Ifyoustudyhard,youwillpasstheexam.3.原因状语从句(1)原因状语从句通常由because,since,as引导。例如：Hedidn’tcometoschoolbecausehewasill.Asitisraining,weshallnotgothezoo.Sinceyoucan’tanswerthequestion,I’llasksomeoneelse.(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：------Whyaren’tgoingthere?

------BecauseIdon’twantto.Ashehasnocar,hecan’tgetthereeasily.Sincewehavenomoney,wecan’tbuyit.(3)because和so不能同用在一个句子里。4.结果状语从句(1)结果状语从句由so…that,such…that,sothat引导。例如：Heissopoorthathecan’tbuyabikeforhisson.Sheissuchagoodteacherthateverybodylikesher.Mypencilfellunderthedesk,sothatIcouldn’tseeit.(2)so…that语such...that可以互换。例如：在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是:“...so+形容词（副词）+that+从句”。例如：Hewassogladthathecouldn’tsayaword.Thehallissobigthatitcanhold2,000people.Motherlivessofarawaythatwehardlyeverseeher.在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：Itwassuchahotdaythatnobodywantedtodoanything.Hehadsuchlongarmsthathecouldalmosttouchtheceiling.Hemadesuchrapidprogressthathedidverywellinthemid-term.有时上述两种结构是可以互换的。例如：Itwassuchawonderfulfilmthatallofuswantedtoseeitagain.=Thefilmwassowonderfulthatallofuswantedtoseeitagain.Itissuchanimportantmatchthatnobodywantstomissit.=Thematchissoimportantthatnobodywantstomissit.(3)如果名词前由many,much,little,few等词修饰时，只能用so,不用such。例如：Soonthereweresomanydeerthattheyateupallthewildroses.Hehassolittletimethathecan’tgotothecinemawithyou.5.比较状语从句比较状语从句通常由as…as,比较级+than…等连词引导。例如：TomrunsfasterthanJohndoes.Thisclassroomisasbigasthatone.6.目的状语从句(1)目的状语从句通常由sothat,inorderthat引导。例如：Westartedearlysothatwecouldcatchthefirsttrain.Hestudieshardsothathecouldworkbetterinthefuture.Weusedthecomputerinorderthatwemightsavetime.(2)sothat既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can,could,may,might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：Speakclearlysothattheymayunderstandyou.(目的状语从句)Jackisbadlyillsothathehastorest.(结果状语从句)7.让步状语从句(1)让步状语从句通常由although,though等连词引导。例如：Thoughheisyoung,heknowsalot.AlthoughIamtired,Imustgoonworking.(2)although(though)不能用在同一个句子中。例如：我们不能说：Thoughitwasraininghard,buthestillwentout.应该说：Thoughitwasraininghard,hestillwentout.或Itwasraininghard,buthestillwentout.8.地点状语从句地点状语从句常常由where来引导。例如：Gowhereyoulike.Wherethereisawill,thereisaway.【实例解析】1.(北京市海淀区试题)Youwillstayhealthy_______youdomoreexercise,suchasrunningandwalking.A.ifB.howC.beforeD.where答案：A。该题考查的是引导状语从句的从属连词的选择。从意思上看，从句应是一个条件状语从句，在这四个选项中只有if能引导条件状语从句，所以选A。2.(江西省试题)---Shallwegoonworking?---Yes,_________Iprefertohavearest.A.whenB.ifC.becauseD.though答案：D。该题考查的是引导状语从句的从属连词的选择。从意思上看，只有选though才能说得通。3.(徐州市试题)Noneofusknewwhathadhappened_________theytoldusaboutit.A.whenB.untilC.afterD.though答案：B。该题考查的是引导状语从句的从属连词选择。本句的意思是“在……以前我们没人知道这件事。”要表达着一意思应用“not…until”这一句型。4.(泉州市试题)---Ihopeyou’llenjoyyourtrip,dear!---Thankyou,mum.I’llgiveyouacall_________Igetthere.A.untilB.assoonasC.sinceD.till答案：B。该题考查的是引导状语从句的从属连词的选择。本题的意思是“一到那里，我就给你打电话。”要表达这个意思应选用assoonas。【演练】一.单项填空1._______he’sold,hecanstillcarrythisheavybag.A.ThoughB.SinceC.ForD.So2.---Doyouknowifhe_______toplaybasketballwithus?---Ithinkhewillcomeifhe______freetomorrow.A.comes;isB.comes;willbeC.willcome;isD.willcome;willbe3.Inthezooifachild_____intothewaterandcan’tswim,thedolphinsmaycomeup______him.A.willfall;tohelpB.falls;tohelpC.willfall;helpD.falls;helping4.Idon’tremember________heworkedinthatcitywhenhewasyoung.A.whatB.whichC.whereD.who5.Wewillstayathomeifmyaunt________tovisitustomorrow.A.comesB.comeC.willcomeD.iscoming6.Thepoliceaskedthechildren_______crossthestreet________thetrafficlightsturnedgreen.A.not;beforeB.don’t;whenC.notto;untilD.not;after7.Iwaslateforclassyesterday_______therewassomethingwrongwithmybike.A.whenB.thatC.untilD.because8.I’llgoswimmingwithyouifI________freetomorrow.A.willbeB.shallbeC.amD.was9.Intheexam,the________youare,______the_______mistakesyouwillmake.A.careful;littleB.morecareful;fewestC.morecareful;fewerD.morecareful;less10.Youshouldfinishyourlessons_______yougoouttopaly.A.beforeB.afterC.whenD.while11.Ihurried_____Iwouldn’tbelateforclass.A.sinceB.sothatC.asifD.unless12.Whenyoureadthebook,you’dbettermakeamark_______youhaveanyquestions.A.whichB.thatC.whereD.though13.Theteacherraisedhisvoice_______allthestudentscouldhearhim.A.forB.sothatC.becauseD.inorder14.Hetookoffhiscoat_______hefelthot.A.becauseB.asC.ifD.since15.Itis______thatwe’dliketogooutforawalk.A.alovelydayB.toolovelyadayC.solovelyadayD.suchlovelyaday16.Maryhad______muchworktodothatshestayedatherofficeallday.A.suchB.soC.tooD.very17._______Ifeltverytired,Itriedtofinishthework.A.AlthoughB.BecauseC.AsD.Asif18.______thedaywenton,theweathergotworse.A.WithB.SinceC.WhileD.As19.______wellyoucandrive,youmustdrivecarefully.A.SolongasB.InorderthatC.NomatterhowD.Themoment20.Writetomeassoonasyou________toBeijing.A.willgetB.getC.gettingD.got二.根据中文意思完成下列英语句子1.不管他跟我开什麽玩笑，我都不生气。Iamnotangrywithhim,____________________jokeshe______onme.2.布鲁斯太太对学生非常亲切，以至于学生把她当做母亲。MrsBrucewas_______kindtoherstudents______they______her_____theirmother.3.只要我们竭尽全力，父母就会满意我们的表现。Ourparentswillbepleasedwithourperformance________________wetryourbest.4.你一到上海就给我打个电话好吗？Willyoupleasecallme__________________yougettoShanghai.5.这个七岁的女孩酷爱钢琴，以至于他已经坚持练习两年了。Theseven-year-oldgi
