1、初中狀語從句考點(diǎn)概括初中狀語從句考點(diǎn)概括初中狀語從句考點(diǎn)概括狀語從句狀語從句指句子用作狀語時(shí)，起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或整個(gè)句子。依據(jù)其作用可分為時(shí)間、地址、原由、條件、目的、結(jié)果、退步、方式和比較等從句。狀語從句一般由連詞(隸屬連詞)指引，也可以由詞組惹起。從句位于句首或句中時(shí)平常用逗號與主句分開，位于句尾時(shí)可以不用逗號分開。?1.時(shí)間狀語從句(1)時(shí)間狀語從句常用when,as（當(dāng).時(shí)候）,while,before,after,since,till,until,assoonas等連詞來指引。比方：HehadlearnedalittleChinesebefor

2、ehecametoChina.Afterhefinishedmiddleschool,hewenttoworkinafactory.(2)在時(shí)間狀語從句里，主句用未來時(shí)態(tài)時(shí)，從句平常不用未來時(shí)態(tài)，用此刻時(shí)態(tài)表示未來的動作或狀態(tài)。（主將從現(xiàn)）比方：IllringyouupassoonasIgettoNewYork.Iwilltellhimeverythingwhenhecomesback.Hewontbelieveituntilheseesitwithhisowneyes.(3)在帶有till或until指引的時(shí)間狀語從句的主從復(fù)合句里，假如主句用必然式，其含義是“向抵達(dá)時(shí)”，謂語動詞只好用連續(xù)

3、性動詞。假如主句用否認(rèn)式，其含義是“直到才”,“在以前不”,謂語動詞可用瞬時(shí)性動詞。比方：Theyoungmanreadtillthelightwentout.Letswaituntiltherainstops.WewontstartuntilBobcomes.Dontgetoffuntilthebusstops.2.條件狀語從句(1)條件狀語從句平常由if,unless(除非)指引。比方：Whatshallwedoifitsnowstomorrow?DontleavethebuildingunlessItellyouto.(2)在條件狀語從句里，謂語動詞平常用此刻時(shí)態(tài)表示未來的動作或狀態(tài)。（

4、主將從現(xiàn)）比方：（必考）IllhelpyouwithyourEnglishifIamfreetomorrow.Hewontbelateunlessheisill.(3)“祈使句+and(or)+陳說句”在乎思上相當(dāng)于一個(gè)帶有條件狀語從句的復(fù)合句。比方：Hurryup,oryoullbelate.=Ifyoudonthurryup,youllbelate.Studyhardandyouwillpasstheexam.=Ifyoustudyhard,youwillpasstheexam.3.原由狀語從句(1)原由狀語從句平常由because,since,as指引。比方：Hedidntcometos

5、choolbecausehewasill.Asitisraining,weshallnotgothezoo.Sinceyoucantanswerthequestion,Illasksomeoneelse.(2)because表示直接原由，語氣最強(qiáng)。Because指引的原由狀語從句多放在主句今后。As和since語氣較弱，一般用來表示明顯的原由。由as和since指引的原由狀語從居多放在句首。比方：-Whyarentgoingthere?-BecauseIdontwantto.Ashehasnocar,hecantgetthereeasily.Sincewehavenomoney,wecantb

6、uyit.(3)because和so不可以同用在一個(gè)句子里。4.結(jié)果狀語從句(1)結(jié)果狀語從句由sothat,suchthat指引。比方：Heissopoorthathecantbuyabikeforhisson.Sheissuchagoodteacherthateverybodylikesher.(2)sothat與such.that可以交換（可能會考）。比方：在由so.that指引的結(jié)果狀語從句中，so是副詞，與形容詞連用。其構(gòu)造是:“.so+形容詞（副詞）+that+從句”。比方：Motherlivessofarawaythatwehardlyeverseeher.在由suchthat指

7、引的結(jié)果狀語從句中，such是形容詞，它修飾的可以是單數(shù)或復(fù)數(shù)可數(shù)名詞，也可以是不可以數(shù)名詞；名詞前面可以帶形容詞，也可不帶。假如是單數(shù)可數(shù)名詞，前面需加不定冠詞a或an。比方：Itwassuchahotdaythatnobodywantedtodoanything.有時(shí)上述兩種構(gòu)造是可以交換的。比方：Itwassuchawonderfulfilmthatallofuswantedtoseeitagain.=Thefilmwassowonderfulthatallofuswantedtoseeitagain.Itissuchanimportantmatchthatnobodywantstomi

8、ssit.=Thematchissoimportantthatnobodywantstomissit.(3)假如名詞前由many,much,little,few等詞修飾時(shí)，只好用so,不用such。比方：Soonthereweresomanydeerthattheyateupallthewildroses.Hehassolittletimethathecantgotothecinemawithyou.5.比較狀語從句比較狀語從句平常由asas（否認(rèn)notso/as.as）,比較級+than等連詞指引。比方：TomrunsfasterthanJohndoes.Thisclassroomisasb

9、igasthatone.6.目的狀語從句(1)目的狀語從句平常由sothat,inorderthat指引。比方：Westartedearlysothatwecouldcatchthefirsttrain.Hestudieshardsothathecouldworkbetterinthefuture.Weusedthecomputerinorderthatwemightsavetime.(2)sothat既可指引目的狀語從句，又可指引結(jié)果狀語從句。差別這兩種從句的方法有兩個(gè)：1)目的狀語從句里經(jīng)常帶有神態(tài)動詞can,could,may,might等。2)從意思上看，目的狀語從句經(jīng)常表示的目的很明

10、確。比方：Speakclearlysothattheymayunderstandyou.目(的狀語從句)Jackisbadlyillsothathehastorest.結(jié)(果狀語從句)7.退步狀語從句(1)退步狀語從句平常由although,though等連詞指引。比方：Thoughheisyoung,heknowsalot.AlthoughIamtired,Imustgoonworking.(2)although(though)與but不可以用在同一個(gè)句子中。比方：我們不可以說：Thoughitwasraininghard,buthestillwentout.應(yīng)當(dāng)說：Thoughitwasr

11、aininghard,hestillwentout.或Itwasraininghard,buthestillwentout.8.地址狀語從句地址狀語從句經(jīng)常由where來指引。比方：Gowhereyoulike.Wherethereisawill,thereisaway.易混指引詞while,when的差別：1.when既可以指時(shí)間點(diǎn),與瞬時(shí)動詞連用，也可以指時(shí)間段，與連續(xù)性動詞連用（=while）。如：Whenhecamein,hismotherwascooking.When(While)wewereatschool,wewenttothelibraryeveryday.While表示時(shí)間段

12、,所以，while從句的謂語動詞要用連續(xù)性動詞。如：Pleasedonttalksoloudwhileothersareworking.2Because,as,since的差別：Because用于表示直接原由,回答why提出的問題，語氣最強(qiáng)；As用于說明原由,著要點(diǎn)在主句，常譯成因?yàn)椋籹ince表示明顯的或已知的原由或事實(shí)，常譯成既然。如：Waterisveryimportantbecausewecantlivewithoutit.Hedidntcomeyesterdayashismotherwasill.Illdoitforyousinceyouarebusy.【實(shí)例解析】1.Youwill
