2、ehecametoChina.Afterhefinishedmiddleschool,hewenttoworkinafactory.(2)在时间状语从句里，主句用未来时态时，从句平常不用未来时态，用此刻时态表示未来的动作或状态。（主将从现）比方：IllringyouupassoonasIgettoNewYork.Iwilltellhimeverythingwhenhecomesback.Hewontbelieveituntilheseesitwithhisowneyes.(3)在带有till或until指引的时间状语从句的主从复合句里，假如主句用必然式，其含义是“向抵达时”，谓语动词只好用连续

3、性动词。假如主句用否认式，其含义是“直到才”,“在以前不”,谓语动词可用瞬时性动词。比方：Theyoungmanreadtillthelightwentout.Letswaituntiltherainstops.WewontstartuntilBobcomes.Dontgetoffuntilthebusstops.2.条件状语从句(1)条件状语从句平常由if,unless(除非)指引。比方：Whatshallwedoifitsnowstomorrow?DontleavethebuildingunlessItellyouto.(2)在条件状语从句里，谓语动词平常用此刻时态表示未来的动作或状态。（

4、主将从现）比方：（必考）IllhelpyouwithyourEnglishifIamfreetomorrow.Hewontbelateunlessheisill.(3)“祈使句+and(or)+陈说句”在乎思上相当于一个带有条件状语从句的复合句。比方：Hurryup,oryoullbelate.=Ifyoudonthurryup,youllbelate.Studyhardandyouwillpasstheexam.=Ifyoustudyhard,youwillpasstheexam.3.原由状语从句(1)原由状语从句平常由because,since,as指引。比方：Hedidntcometos

5、choolbecausehewasill.Asitisraining,weshallnotgothezoo.Sinceyoucantanswerthequestion,Illasksomeoneelse.(2)because表示直接原由，语气最强。Because指引的原由状语从句多放在主句今后。As和since语气较弱，一般用来表示明显的原由。由as和since指引的原由状语从居多放在句首。比方：-Whyarentgoingthere?-BecauseIdontwantto.Ashehasnocar,hecantgetthereeasily.Sincewehavenomoney,wecantb

6、uyit.(3)because和so不可以同用在一个句子里。4.结果状语从句(1)结果状语从句由sothat,suchthat指引。比方：Heissopoorthathecantbuyabikeforhisson.Sheissuchagoodteacherthateverybodylikesher.(2)sothat与such.that可以交换（可能会考）。比方：在由so.that指引的结果状语从句中，so是副词，与形容词连用。其构造是:“.so+形容词（副词）+that+从句”。比方：Motherlivessofarawaythatwehardlyeverseeher.在由suchthat指

7、引的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可以数名词；名词前面可以带形容词，也可不带。假如是单数可数名词，前面需加不定冠词a或an。比方：Itwassuchahotdaythatnobodywantedtodoanything.有时上述两种构造是可以交换的。比方：Itwassuchawonderfulfilmthatallofuswantedtoseeitagain.=Thefilmwassowonderfulthatallofuswantedtoseeitagain.Itissuchanimportantmatchthatnobodywantstomi

8、ssit.=Thematchissoimportantthatnobodywantstomissit.(3)假如名词前由many,much,little,few等词修饰时，只好用so,不用such。比方：Soonthereweresomanydeerthattheyateupallthewildroses.Hehassolittletimethathecantgotothecinemawithyou.5.比较状语从句比较状语从句平常由asas（否认notso/as.as）,比较级+than等连词指引。比方：TomrunsfasterthanJohndoes.Thisclassroomisasb

11、aininghard,hestillwentout.或Itwasraininghard,buthestillwentout.8.地址状语从句地址状语从句经常由where来指引。比方：Gowhereyoulike.Wherethereisawill,thereisaway.易混指引词while,when的差别：1.when既可以指时间点,与瞬时动词连用，也可以指时间段，与连续性动词连用（=while）。如：Whenhecamein,hismotherwascooking.When(While)wewereatschool,wewenttothelibraryeveryday.While表示时间段

12、,所以，while从句的谓语动词要用连续性动词。如：Pleasedonttalksoloudwhileothersareworking.2Because,as,since的差别：Because用于表示直接原由,回答why提出的问题，语气最强；As用于说明原由,着要点在主句，常译成因为；since表示明显的或已知的原由或事实，常译成既然。如：Waterisveryimportantbecausewecantlivewithoutit.Hedidntcomeyesterdayashismotherwasill.Illdoitforyousinceyouarebusy.【实例解析】1.Youwill
