1.时间状语从句
问题1:
1.(04北京春)Wewereswimminginthelake______suddenlythestormstarted.
A.whenB.whileC.untilD.before
2.(02上海)Hewasabouttotellmethesecret______someonepattedhimontheshoulder.

5.(06辽宁)Hewasabouthalfwaythroughhismeal______afamiliarvoicecametohisears.
A.whyB.whereC.whenD.while
连接词when的用法小结
1.when引导的时间状语从句的谓语动词可以是可延续的,也可以是表短暂性动作的动词,可用于主句和从句动作同时发生或从句动作先于主句动作。
如:
Whenthefilmended,thepeoplewentback.
WhenIlivedthere,IusedtogototheseashoreonSundays.
2.可用作并列连词,其意义为“那时,这时”,相当于andatthis/thattime。
常用于下列句式:
Somebodywasdoingsomething/wasabouttodosth./wasonthepointofdoingsth.when…(刚要……这时突然……)
3.还可以表示原因“既然”,相当于since;consideringthat。
如:
Itwasfoolishofyoutotakeataxiwhenyoucouldeasilywalkthereinfiveminutes.
问题2:
6.(06天津)ThecostoflivinginGlasgowisamongthelowestinBritain,______thequalityoflifeisprobablyoneofthehighest.A.sinceB.whenC.asD.while
7.(04年江苏)______Iacceptthatheisnotperfect,Idoactuallyliketheperson.
A.WhileB.SinceC.BeforeD.Unless
连接词while的用法小结
1.while引导的动作必须是持续性的,侧重主句动作和从句动作相对比。
如:
Pleasedon’ttalksoloudwhileothersareworking.
2.while作为并列连词,意为“而,却”,表示对比。
3.while可表示尽管,相当于although。
连接词when,while,as的用法区别:
1.while引导的时间状语从句的谓语动词必须是可延续的,而when引导的时间状语从句的谓语动词是可延续的,也可以是表短暂性动作的动词。
如:
When/Whilehewas
eatinghisbreakfast,heheardthedoorbellring.WhenIstoppedmycar,amancameuptome.(不可用while)
2.从句动作发生在主句动作之前时,只能用when引导这个从句,不可用as或while。
如:
Whenyouhavefinishedyourwork,youmayhavearest.
3.表示“随着……”,连词用as,不用when或while。
如:
Astheelectionapproached,theviolencegotworse.
4.如果主句表示的是短暂动作,而从句用延续性动作的进行时态表示在一段时间内正在进行的动作时,when,while与as可互换使用。
如:
When/While/AsIwaswalkingdownthestreet,Icameacrossanoldfriendofmine.
问题3:
1.(01北京春)-DidyouremembertogiveMarythemoneyyouowedher?
-Yes.Igaveittoher______Isawher.

3.______enteredtheofficewhenherealizedthathehadforgottenhisreport.
A.HehardlyhadB.HadhehardlyC.HardlyhadheD.Hardlyhehad
小结:
1.一些词,如themoment,theminute,theinstant,immediately,directly,instantly,hardly…when,scarcely…when,nosooner…than等也可引导一个时间状语从句,相当于assoonas的意思。
Ididn’twaitamoment,butcameimmediatelyyoucalled.
2.一些含有time的名词短语,如everytime,eachtime,nexttime,bythetime等,以及theday,theyear,themorning等,也可引导一个时间状语从句。
Thedayhereturnedhome,hisfatherwasalreadydead.
Nexttimeyoucome,pleasebringyourcomposition.
3.如果hardly或nosooner或scarcely置于句首,句子必须用部分倒装结构。
HardlyhadIgothomewhenitbegantorain.
问题4:
1.(03北京春)-Washisfatherverystrictwithhimwhenhewasatschool?
-Yes.Hehadneverpraisedhim______hebecameoneofthetopstudentsinhisgrade.

3.Itwasnot______shetookoffherdarkglasses______Irealizedshewasafamousfilmstar.
A.when;thatB.until;thatC.until;whenD.when;then
小结:
till,until和not…until:
1.until/till引导时间状语从句用于肯定句时,主句的动词是延续性动词,表示动作或状态一直持续到until/till所表示的时间,意为“某动作一直延续到某时间点才停止”。
如:
Wewaiteduntilhecame.
2.用于否定句时,主句谓语动词是非延续性动词,从句为肯定,意为“某动作直到某时间才开始”。
如:
Hewon’tgotobedtill/untilshereturns.
3.till不可以置于句首,而until可以。
如:
UntilyoutoldmeIhadnoideaofit.
4.not…until句型中的强调和倒装说法:
ItwasnotuntilyoutoldmethatIhadanyideaofit.
NotuntilyoutoldmedidIhaveanyideaofit.
问题5:
1.(03年北京)Hemadeamistake,butthenhecorrectedthesituation______itgotworse.

A.beforeB.untilC.whenD.after
4.(05北京春)Itisalmostfiveyears______wesaweachotherlasttime.
A.beforeB.sinceC.afterD.because
连接词before的小结:
一、含义
1.Wehadsailedfourdaysandfournightsbeforewesawland.
2.Wehadn’trunamilebeforehefelttired.
3.Pleasewriteitdownbeforeyouforgetit.
4.BeforeIcouldgetinaword,hehadmeasuredme.
二.Before从句中谓语不用否定式。
如:
Beforetheyreachedthestation,thetrainhadgone.
三.1)句型Itwillbe/was+段时间+before…“还要过多久才……”
如:
Itwillbetwoyearsbeforeheleavesthecountry.
2)句型Itwillbe/wasnot+一段时间+before…“不多久就……”
如:
Itwasn’ttwoyearsbeforeheleftthecountry.
3)句型Itis+段时间+since…时间的计算一律从since从句的动作完成或状态结束时算起。
如:
Itisthreeyearssinceshewasinthearmy.
Itisthreeyearssinceshejoinedthearmy.
2、条件状语从句
问题1:
1、TheWTOcannotliveuptoitsname____itdoesnotincludeacountrythatishometoonefifthofmankind.(2000全国)
A.aslongasB.while C.ifD.eventhough
2、Itisknowntoallthat_____youexerciseregularly,youwon’tkeepgoodhealth.(05重庆卷)
A.unlessB.wheneverC.althoughD.if
unless相当于ifnot,意思是“除非…”“如果不…就…”。
这也是高考的热点之一。
复习时也应给予高度重视。
问题2:
1、_____Icansee,thereisonlyonepossiblewaytokeepawayfromthedanger.(04北京春季)
A.AslongasB.AsfarasC.JustasD.Evenif
2、IalwaystakesomethingtoreadwhenIgotothedoctor’s________Ihavetowait.(05全国卷3)
A.incaseB.sothatC.inorderD.asif
aslongas与asfaras都可引导条件状语从句,aslongas表示“只要…”,asfaras表示“就…而论(而言)”。
题1根据题意应该选用B。
incase表示“以防”,根据题2的句意,不难作出选择。
3、让步状语从句
问题1:
1、_____Iacceptthatheisnotperfect,Idoactuallyliketheperson.(04江苏)
A.WhileB.SinceC.BeforeD.Unless
2、Allowchildrenthespacetovoicetheiropinions,____theyaredifferentfromyourown.(05湖
A.untilB.evenifC.unlessD.asthough
while是高考中的高频词,它既可引导时间状语从句,又可引导并列句,还可引导让步状语从句,表示“尽管”。
evenif等于eventhough,表示“即使、尽管”。
asthough等于asif,引导方式状语从句,表示“好像、似乎”。
问题2:
1、Hetriedhisbesttosolvetheproblem,___difficultitwas.(05天津卷)
A.howeverB.nomatterC.whateverDalthough
2、Theoldtowermustbesaved,______thecost.(05浙江)
A.howeverB.whateverC.whicheverD.wherever
nomatterwh-与wh-ever的联系及区别:
nomatterwh-只引导让步状语从句,此时与wh-ever通用。
如:
Nomatterwhen/Wheneverhecomesback,heshouldbeinvitedtotheparty.
wh-ever又可引导名词性从句,Nomatterwh-不能。
如:
WhateverIcandoforyouwillbenothingbutpayingadebt.Whoevercanhelpuswillbewelcome.
4.状语从句的时态问题
问题1:
1、Thehousecouldfalldownsoonifnoone______somequickrepairwork.(04全国IV)
AhasdoneBisdoingCdoesDhaddone
2、Itisalmostfiveyears_______wesaweachotherlasttime.(05北京春季)
A.beforeB.sinceC.afterD.when
在条件,时间和让步从句中,用一般现在时表示一般将来时,用现在完成时表将来完成时,用一般过去时表过去将来时。
在since引导的时间状语从句中,动词一般都用一般过去时,而主句常用现在完成时。
5、状语从句的倒装问题
问题1:
1、Sodifficult_____ittoliveinanEnglish-speakingcountrythatIdeterminedtolearnEnglish.(01)
A.IhavefeltB.haveIfeltC.IdidfeelD.didIfeel
2、Notuntilallthefishdiedintheriver_____howseriousthepollutionwas.(95NMET)
A.didthevillagersrealizeB.thevillagersrealized
C.thevillagersdidrealizeD.didn’tthevillagersrealize
状语从句的倒装一般有下面几种情况:
①否定词开头;②so加adj.开头;③as/though引导的让步状语从句。
特别注意:
Hardly…when…Nosooner…than…Childasheis,…
Hardlyhadhegottothestationwhenthetrainleft.
Nosoonerhadhegottothestationthanthetrainleft.
Childasheis,hecanspeaksevenforeignlanguages.
6、状语从句与并列句的区别
问题1:
1、Thoughheisinhissixties,______heworksashardasayoungman
A.yetB.butC.andD.andyet
2、Excusemeforbreakingin,_________Ihavesomenewsforyou.(NMET02)
A.so B.and C.but D.yet
题1是主从复合句,所以中间不能使用并列连词and;or;but;so等。
yet是副词,只有yet可以与though连用。
题2为并列句,而“Excuse…,but…”为一固定搭配。
