高中英语状语从句复习教案
1.时间状语从句常见的从属连词有:
（注意其汉语意义
when,while,as,before,after,since,until（tillonceassoonas,themoment,theminute,immediately,directly,each/everytime,thefirsttime,thelasttime,nexttime,bythetime,whenever等。
例如:
Every/EachtimeIwasintrouble,hewouldcometomyhelp.
IthoughtherniceandhonestthefirsttimeImether.注意:
（1when,while,as的区别:
1when引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。
如:
WhenIgottotheairport,theplanehadalreadytakenoff.（主先从后（短暂性
WhenIlivedthere,IusedtogototheseasideonSundays.（同时（持续性
Whenthemovieended,thepeoplewentback.（从先主后
2while侧重主从句动作的对比,且从句的动词必须是持续性的。
如:
Whilewewerechattingshewaslookingatthetimetableonthewall.
3as引导从句时侧重主从句动作同时或几乎同时进行,从句的动作可以是持续性的,也可以是短暂的。
如:
SometimesIwatchTVasIamhavingbreakfast.
4when和while还可以是并列连词,意思分别是―就在这时‖,―然而‖。
如:
Iwashavingarestonthesofawhenthetelephonerang.
Theyweresurprisedthatachildshouldworkouttheproblemwhiletheycouldn’t.注:
并列连词when常用与以下句型中:
①…was/weredoing…when…（正在做…突然
②…was/wereabouttodo…when…（刚要做…突然
③…was/wereonthepointofdoing…when…（刚要做…突然
④…hadjustdone…when….（刚一…就
⑤Hardly/Scarcelyhad…done…when…（刚一…就
（2before引导从句时,词义非常灵活,注意下列句子中的before的词义:
1.BeforeIcouldgetinaword,thetailorhadmeasuredme.（还没来得及…就
2.Wehadn’trunamilebeforehefelttired.（还没…就
3.Wehadsailed4daysbeforewesawland.（…才…
4.Pleasewriteitdownbeforeyouforgetit.（趁还…没就
（3till（until和not…till（until
1till（until:
主句谓语动词必须是持续性的,意思是―到…为止―如:
Heremainedtheretill/untilshearrived.
2not…till（until…:
主句谓语动词必须是短暂性的,意思是―直到…才‖如:
Shewon’tgotobedtill/untilhereturnshome.
3not…until还有强调式和倒装式:
强调句:
Itisnotuntilhereturnshomethatshewillgotobed.
倒装句:
Notuntilhereturnshomewillshegotobed.
（4几个极易混淆的时间状语从句:
1Itwas+时间点+when…（当的时候时间是
Itwas5amwhenwearrivedatthevillage.
2Itwas/willbe+时间段+before…（没过…就/过了…才
Itwas/willbetwoweeksbeforewemet/meetagain.
3Itis/hasbeen+时间段+since…（自从…以来有…
Itis/hasbeen3yearssincewelastmet.
突破点:
一看be动词的时态,二看时间段还是时间点。
注意:
在―Itis/hasbeen+时间段+since…‖句型中,从句的动词必须是短暂性的,如果是延续性的动词,时间要从从句的动作结束时算起。
如:
Itis3yearssinceIsmoked.（我戒烟有三年了
2.条件状语从句常见的从属连词有:
if,unless,as/solongas,as/sofaras,onconditionthat,incase（万一,themore…,themore…等。
如:
As/SofarasIcansee（amconcerned,itwillbeimpossibleforthemtofinishthetask.
Themorebooksyouread,thehappieryouwillfeel.（前面为从句
3.原因状语从句常见的从属连词有:
because,since,nowthat,as等。
注意because,since,as的区别:
1why的语气最强,它引导的从句比主句更重要,从句的位置可前可后;例外回答why的问句必须使用because。
如:
-Whywereyouabsentfromthemeetingyesterday?
-BecauseIwasill.
2since和nowthat意思是―既然‖,语气仅次于because,从句的位置一般在前。
如:
Sinceeverybodyishere,let’sbeginourmeeting.
3as的语气比since更弱,意思是―由于‖,
从句的位置可前可后。
如:
Asyoudidn’tturnupatyesterday’sget-together,wemissedyouverymuch.
4*for也有―因为‖之意,但for是并列连词常用来来补充说明原因或用来表示推断的依据,前面常带逗号。
如:
Itmusthaverainedlastnight,forthegroundiswet.
4.让步状语从句常见的从属连词有:
though,although,as,evenif/though,nomatterwh-,wh-ever,whether…or…等。
如:
Howeverlate/Nomatterhowlateheis,hisfamilywillwaitforhimtohavedinnertogether.
Childasheis,heknowsalot.（as引导的让步状语从句必须倒装
Whetheritisfineornot,Iwillgoboating.
5.地点状语从句常见的从属连词有:
*where,wherever等。
如:
Putthebookwhereitis.
6.比较状语从句常见的从属连词有:
*as…as,*notso（as…as,*than等。
注意:
（1在表达倍数时,可用三种句型:
1A…+倍数+比较级+thanB如:
Thisbuildingistwicetallerthanthatone.
2A…+倍数+as原级as+B如:
Thisbuildingisthreetimesastallasthatone.
3A…+倍数+thesize（height,weight,lengthetc.+ofB如:
Thisbuildingisthreetimesthesizeofthatone.
（2三种句型变式:
1倍数+more+名词+than
2*倍数+asmany/much+名词+as
Americanseatmorethantwiceasmanyvegetablesperpersontodayastheydidin1910.
ItisreportedthattheUnitedStatesusestwiceasmuchenergyasthewholeofEurope.
7.方式状语从句常见的从属连词有:
as,asif/though等.注意:
asif/though引导的从句常用虚拟语气,表示非真实情况.
Hetalksaboutthemoonasifhehadbeenthere.（从句动作先发生
Shetreatedtheboyasifhewere/washerownchild.（主从句动作同时发生
8.目的状语从句常见的从属连词有:
sothat,that,inorderthat,incase（以免,forfearthat等。
如:
Moststudentsgotocollege（sothattheycanbeengineers,teachersorchemists.注意:
从句中的情态动词can,could,may,might等提示为目的状语从句.
9.结果状语从句常见的从属连词有:
so…that,such…that,sothat等。
如:
Heearnedsolittlemoneythathecouldn’tsupporthisfamily.

三、用法灵活的as,when,while引导的状语从句
1.as可以引导时间、原因、让步、比较和方式等5种状语从句。
2.when可以引导时间、条件和原因等3种状语从句。
Howcanweexplainittoyouwhen（=ifyouwon'tlisten.
Itwasfoolishofyoutotakeataxiwhenyoucouldeasilywalktherein5minutes
3.while可以引导时间、让步、条件和原因等4种状语从句。

While（=Aslongasthereislifethereishope.
--I’mgoingtothepostoffice.
–While（=Sinceyouarethere,canyougetmesomestamps?
四、状语从句的省略
当时间、条件、让步、方式和比较状语从句的主语与主句一致或为it或there且谓语动词含be动词时,从句中的主语和谓语可以一起省去。
例如:
Don’tspeakuntilspokento.（省略了youare
Ihavenomoney.Ifany,Iwilllendyousome.（省略了thereis
Thoughcold,hestillworeashirt.（省略了itwas
Someflowersshutupatnightasiftosleep.（省略了theywere
五、状语从句与定语从句的转换

→Makemarksattheplaceswhereyouhavequestions.（定语从句
2Itissuchanadvancedtheorythatfewpeopleunderstandit.（结果状语从句
→Itissuchanadvancedtheoryasfewpeopleunderstand.（定语从句
