初中狀語從句考點歸納

1、初中狀語從句考點概括初中狀語從句考點概括初中狀語從句考點概括狀語從句狀語從句指句子用作狀語時，起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或整個句子。依據其作用可分為時間、地址、原由、條件、目的、結果、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平常用逗號與主句分開，位于句尾時可以不用逗號分開。?1.時間狀語從句(1)時間狀語從句常用when,as（當.時候）,while,before,after,since,till,until,assoonas等連詞來指引。比方：HehadlearnedalittleChinesebefor

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

3、性動詞。假如主句用否認式，其含義是“直到才”,“在以前不”,謂語動詞可用瞬時性動詞。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態(tài)表示未來的動作或狀態(tài)。（

4、主將從現）比方：（必考）IllhelpyouwithyourEnglishifIamfreetomorrow.Hewontbelateunlessheisill.(3)“祈使句+and(or)+陳說句”在乎思上相當于一個帶有條件狀語從句的復合句。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。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不可以同用在一個句子里。4.結果狀語從句(1)結果狀語從句由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指引的結果狀語從句中，so是副詞，與形容詞連用。其構造是:“.so+形容詞（副詞）+that+從句”。比方：Motherlivessofarawaythatwehardlyeverseeher.在由suchthat指

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

8、ssit.=Thematchissoimportantthatnobodywantstomissit.(3)假如名詞前由many,much,little,few等詞修飾時，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，又可指引結果狀語從句。差別這兩種從句的方法有兩個：1)目的狀語從句里經常帶有神態(tài)動詞can,could,may,might等。2)從意思上看，目的狀語從句經常表示的目的很明

10、確。比方：Speakclearlysothattheymayunderstandyou.目(的狀語從句)Jackisbadlyillsothathehastorest.結(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不可以用在同一個句子中。比方：我們不可以說：Thoughitwasraininghard,buthestillwentout.應當說：Thoughitwasr

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

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；As用于說明原由,著要點在主句，常譯成因為；since表示明顯的或已知的原由或事實，常譯成既然。如：Waterisveryimportantbecausewecantlivewithoutit.Hedidntcomeyesterdayashismotherwasill.Illdoitforyousinceyouarebusy.【實例解析】1.Youwill
