外研社九年級(jí)上冊(cè)狀語(yǔ)從句語(yǔ)法課件(52張)

狀語(yǔ)從句專題講解思考1：什么是狀語(yǔ)？1）對(duì)謂語(yǔ)動(dòng)詞進(jìn)行補(bǔ)充、說(shuō)明和完善的成分，我們稱之為狀語(yǔ)。Eg:IspeakEnglishwell.Iruninthemorning.我就是狀語(yǔ)~思考2：什么是狀語(yǔ)從句？Iwillcall

you

tomorrow.Iwillcall

you

whenhecomes.從句主句主句+連接詞+從句當(dāng)狀語(yǔ)部分是由句子構(gòu)成的時(shí)候，我們稱這樣的句子為狀語(yǔ)從句。思考3：狀語(yǔ)從句考什么？1、分清楚狀語(yǔ)從句類型2、選好連接詞3、注意特殊時(shí)態(tài)用法時(shí)間狀語(yǔ)從句地點(diǎn)狀語(yǔ)從句原因狀語(yǔ)從句結(jié)果狀語(yǔ)從句目的狀語(yǔ)從句條件狀語(yǔ)從句讓步狀語(yǔ)從句Iwillcallyouwhenhecomes.We?must?camp?where?we?can?get?water.Heisunhappytodaybecausehewasill.Heissofatthathemustdosportseveryday.Hegotupearlysothathecouldcatchthebus.Youwillgotocollege,ifyoustudyhard.Althoughyouwerelateforschool,Iwasn'tangry.狀語(yǔ)從句分類時(shí)間狀語(yǔ)從句其中對(duì)動(dòng)作發(fā)生的時(shí)間進(jìn)行描述的從句

when,while,before,after,until,since,assoonas......時(shí)間狀語(yǔ)從句主從句之間的連接詞1、從句動(dòng)作既可以是延續(xù)性動(dòng)詞，也可以是短暫性動(dòng)詞，如：when短暫性動(dòng)詞延續(xù)性動(dòng)詞1.Thestudentswereplayingcomputergameswhentheteachercamein.2.WhenIwaswalkingalong,Icameacrossafriendofmine.短暫性動(dòng)詞延續(xù)性動(dòng)詞時(shí)態(tài)2、時(shí)態(tài)的用法：主現(xiàn)從現(xiàn)、主過(guò)從過(guò)、主將從現(xiàn)when1、IalwaysdrinkcoffeewhenIwork.2、Whenhegavemeapresent,Ithankedhim.3、Wewillgooutforawalkwhentheweatherisfine。時(shí)態(tài)主現(xiàn)從現(xiàn)主過(guò)從過(guò)主將從現(xiàn)

1、從句必須是延續(xù)性動(dòng)詞Someoneknockedthedoorwhilewewerehavingsupper.while

2、強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)發(fā)生，主從句都用進(jìn)行時(shí)，只能用while.IwaswatchingTVwhilemymotherwascooking.while1.肯定句：

。。。直到。。。（表示主句發(fā)生的動(dòng)作一直持續(xù)到某一時(shí)間才停止，因此，主句動(dòng)詞要使用延續(xù)性動(dòng)詞）Ihavetostayhere

untiltherainstops.IwatchedTV

untilmymotherreturnedlastnight.until2.主句用于否定句：not.....，until...

直到。。。才。。。表示主句的動(dòng)作一直持續(xù)到某時(shí)才開(kāi)始，主句動(dòng)詞既可以是延續(xù)動(dòng)詞，也可以是瞬間動(dòng)詞。Hedidn'tdohishomeworkuntilhisfathercamehome.3.時(shí)態(tài)Hedidn'tdohishomeworkuntilhisfathercamehome.Shedoesn'twatchTVuntilshefinishesherhomeworkeveryday.Iwon'tgooutuntilIfinishmyhomework.主過(guò)從過(guò)主將從現(xiàn)主現(xiàn)從現(xiàn)before:在。。。之前

（主句動(dòng)作發(fā)生在從句動(dòng)作之前）Youmustbrushyouteethbeforeyougotobed.

after:在。。。之后（主句動(dòng)作發(fā)生在從句動(dòng)作之后）Youmustclosethedoorafteryougotowork.

since:自從

（主句現(xiàn)在完成時(shí)，從句一般過(guò)去時(shí)）IhavebeenheresinceIwasyoung.

assoonas:一。。。就。。。重點(diǎn)：時(shí)態(tài)用法上以主將從現(xiàn)最為常見(jiàn)。Wewillgototheparkassoonastherainstops.

因?yàn)槲易孕熊嚦鰡?wèn)題了。because?；卮饂hy引導(dǎo)的疑問(wèn)句，從句一般位于主句后；why引導(dǎo)的問(wèn)句，從句一般位于主句前。易錯(cuò)點(diǎn)2because和so不能同在一個(gè)句子中。BecauseIwasafraid,Ididn’tgothere.BecauseIwasafraid,soIdidn’tgothere.易錯(cuò)點(diǎn)3because和becauseof也有明顯區(qū)別。because后面要跟從句，而becauseof后面跟名詞短語(yǔ)。Heislateforschoolbecauseitrainsheavily.Heislateforschoolbecauseoftheheavyrain.【典例2】Hewaslate_______theheavyrain.A.becauseB.becauseofC.thoughD.if

讓步狀語(yǔ)從句表示：雖然，盡管，即使等概念讓步狀語(yǔ)從句連接詞大觀althoughwhatever=盡管，雖然無(wú)論什么though盡管，雖然nomatterwhat無(wú)論什么evenif

即使However(=Nomatterhow)expensiveitmaybe，I’lltakeit.

NomatterwhatIsayorhowIsayit，healwaysthinksI’mwrong.

EvenifIhavetowalkallthewayI’llgetthere.

Itwasanexcitinggame，though/althoughnogoalswerescored.這兩個(gè)連詞意思大致相同，在一般情況下可以互換使用。在口語(yǔ)中，though較常使用，although比though正式，二者都可與yet，still連用，但不能與but連用。例如：易錯(cuò)點(diǎn)1⑴though，although表示“雖然，縱然”之意ThoughIbelieveit,yetImustconsider.盡管我相信這一點(diǎn)，但我還得考慮考慮。目的狀語(yǔ)從句目的狀語(yǔ)從句：從句部分是用以補(bǔ)充說(shuō)明主句中謂語(yǔ)動(dòng)詞發(fā)生的目的的狀語(yǔ)從句。引導(dǎo)目的狀語(yǔ)從句常用的連詞有：

sothat（以便），inorderthat（為了；以便）E.g.Youmustspeakmoreloudlysothatyoucanbeheardbyall.(該句為目的狀語(yǔ)從句的普遍形式）【注意】inorderthat與inorderto的區(qū)別：inorderthat+從句inorderto+動(dòng)詞原形（叫目的狀語(yǔ)）E.g.Igetupearlyinordertocatchtheearlybus.inorderthat為了，后接從句，做目的狀語(yǔ)。E.g.

IgetupearlyinorderthatIcancatchtheearlybus.易錯(cuò)點(diǎn)1結(jié)果狀語(yǔ)從句描述動(dòng)作發(fā)生的結(jié)果簡(jiǎn)介結(jié)果狀語(yǔ)從句常由so…that或such…that引導(dǎo)，掌握這兩個(gè)句型，首先要了解so和such與其后的詞的搭配規(guī)律。so和such結(jié)果狀語(yǔ)從句其規(guī)律由so與such的不同詞性決定。1、such是形容詞+修飾名詞或名詞詞組2、so是副詞，后面+修飾形容詞或副詞

3、so還可與表示數(shù)量的形容詞many,few,much,little連用，形成固定搭配。易錯(cuò)點(diǎn)1（1）so+adj+that從句

eg：Itwassocoldoutsidethatwehadtostopthegame.

(2)so+adv+that從句

eg：Tomransofastthathewonfirstplace.(3)so+many/much/few/little(少)+名詞+that從句

eg：TherewassomuchworktodothatMarygottired.(4)such+a+形容詞+名詞+that從句eg：Itwassuchacolddaythatwehadtostopthegame.根據(jù)句意，用so或such填空。

sosuchsosuch條件狀語(yǔ)從句其中對(duì)動(dòng)作發(fā)生的條件進(jìn)行描述的從句條件狀語(yǔ)從句連接詞大觀ifaslongas如果，假如只要unless除非，如果不Ifitsnowstomorrow,we’llhaveadayortwooff.在條件狀語(yǔ)從句中，要注意時(shí)態(tài)一致。一般情況下，主句是一般將來(lái)時(shí)，從句用一般現(xiàn)在時(shí)（即“主將從現(xiàn)”或“主情從現(xiàn)”或“主祈從現(xiàn)”）；主句是過(guò)去時(shí)態(tài)，從句也要用相應(yīng)的過(guò)去時(shí)態(tài)。易錯(cuò)點(diǎn)1“主將從現(xiàn)”：條件狀語(yǔ)從句要用一般現(xiàn)在時(shí)態(tài)表示將來(lái)的動(dòng)作。Ifitdoesn’traintomorrow,we’llgotothepark.如果明天不下雨的話，我們就去公園。（從現(xiàn)）（主將）易錯(cuò)點(diǎn)1“主情從現(xiàn)”：條件狀語(yǔ)從句中的主句可能是情態(tài)動(dòng)詞（can,may,might,must,should)+動(dòng)詞原形的形式。Ifyouwanttopasstheexam,youmuststudyhard.如果你想考試及格，你就必須努力學(xué)習(xí)。（從現(xiàn)）（主情）易錯(cuò)點(diǎn)1“主祈從現(xiàn)”：條件狀語(yǔ)從句中的主句可能是祈使句。Ifyouseehim,pleasegivehimthisnote.如果你看見(jiàn)他，把這個(gè)紙條給他。（從現(xiàn)）（主祈）易錯(cuò)點(diǎn)2意為“如果”意為“是否”，=whether引導(dǎo)條件狀語(yǔ)從句。引導(dǎo)賓語(yǔ)從句。遵循“主將從現(xiàn)”“主情從現(xiàn)”“主祈從現(xiàn)”原則。無(wú)此用法。Ifyouwantstoseehim,youcantellhimtowait.如果你想見(jiàn)他的話，叫他等好了。IwonderifIshouldwearahat.我不知道該不該
