考点与难点归纳1、各种从属连词的含义及用法比较；2、nomatterwh-与wh-ever引导的从句的区别；3、状语从句的时态问题；4、状语从句倒装及紧缩问题；5、状语从句与其它从句的区别。考点难点

1.时间状语从句1.Wewereswimminginthelake______suddenlythestormstarted.A.when B.while C.untilD.before2.Hewasabouttotellmethesecret______someonepattedhimontheshoulder.A.as B.until C.while D.when3.－DidJackcomebackearlylastnight?

4.ThecostoflivinginGlasgowisamongthelowestinBritain,______thequalityoflifeisprobablyoneofthehighest.A.since B.whenC.as D.while5.______Iacceptthatheisnotperfect,Idoactuallyliketheperson.A.While B.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。DA

问题3:1.－DidyouremembertogiveMarythemoneyyouowedher?

－Yes.Igaveittoher______Isawher.A.while B.themoment C.suddenly D.once2.Ithoughtherniceandhonest______Imether.A.firsttime B.forthefirsttime C.thefirsttime D.bythefirsttime3.______enteredtheofficewhenherealizedthathehadforgottenhisreport.A.Hehardlyhad B.Hadhehardly C.Hardlyhadhe D.HardlyhehadBCC

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.－Washisfatherverystrictwithhimwhenhewasatschool?

－Yes.Hehadneverpraisedhim______hebecameoneofthetopstudentsinhisgrade.A.after B.unlessC.until D.when2.Itwasnot______shetookoffherdarkglasses______Irealizedshewasafamousfilmstar.A.when;that B.until;that C.until;when D.when;thenCB

连接词before的小结：一、含义1．Wehadsailedfourdaysandfournightsbeforewesawland.2．Wehadn’trunamilebeforehefelttired.3．Pleasewriteitdownbeforeyouforgetit.4．BeforeIcouldgetinaword,hehadmeasuredme.

“……才”“不到……就”“趁……”“还没来得及”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＋一段时间＋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.

A．aslongasB．while

C．ifD．eventhough2、

Itisknowntoallthat_____youexerciseregularly,youwon’tkeepgoodhealth.A.unlessB.wheneverC.althoughD.ifCA

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.A.AslongasB.AsfarasC.JustasD.Evenif

2、IalwaystakesomethingtoreadwhenIgotothedoctor’s________Ihavetowait.A．incase B．sothatC．inorder D．asif

BA

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.A.WhileB.SinceC.BeforeD.Unless2、Allowchildrenthespacetovoicetheiropinions,____theyaredifferentfromyourown.A.until B.evenif C.unless D.asthough

AB

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.A.howeverB.nomatterC.whateverDalthough2、Theoldtowermustbesaved,______thecost.A．howeverB．whateverC．whicheverD．wherever

ABnomatterwh-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.Whoevercanhelpuswillbee.

4.状语从句的时态问题

问题1：

1、Thehousecouldfalldownsoonifnoone______somequickrepairwork.Ahasdone Bisdoing Cdoes Dhaddone

2、Itisalmostfiveyears_______wesaweachotherlasttime.

A.before B.since C.after D.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。CB

5、状语从句的倒装问题

问题1：

1、Sodifficult_____ittoliveinanEnglish-speakingcountrythatIdeterminedtolearnEnglish.A.IhavefeltB.haveIfeltC.IdidfeelD.didIfeel2、Notuntilallthefishdiedintheriver_____howseriousthepollutionwas.A.didthevillagersrealizeB.thevillagersrealizedC.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。DA

Hardly…when…Nosooner…than…Childasheis,…

Hardlyhadhegottothestationwhenthetrainleft.Nosoonerhadhegottothestationthanthetrainleft.

Childasheis,hecanspeaksevenforeignlanguages。特别注意：

6、状语从句与并列句的区别

问题1：

1、Thoughheisinhissixties,______heworksashardasayoungmanA.yet B.but C.and D.andyet2、

Excusemeforbreakingin,_________Ihavesomenewsforyou.

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。题为并列句，而“Excuse…,but…”为一固定搭配。在复习中要细心的分析句子结构和成分。AC对比训练与巩固
