when,while,as,after,before,since,until/till,assoonas,hardly/scarcely…when,nosooner…than,everytime,eachtime,themoment,theminute,thesecond,bythetime,immediately….一、when/while/asWhen+(1)延续性动词

e.g.WhenIwasyoung,Ilikeddancing.(2)瞬间性动词(不能用while）

e.g.Itwassnowingwhenwegottotheairport．

(3)表示“这时”“正在这时候”

e.g.Iwaswalkingonthestreetwhensuddenlysomeonepattedmeontheshoulder.(4)主从句动作先后发生(不能用while）

e.g.WhenIgottothecinema,thefilmhadalreadybegun.While+(1)延续性动词

e.g.WhileIslept,athiefbrokein.(2)表示两种情况对比，“然而”“而”

e.g.Theyweresurprisedthatachildshouldworkouttheproblemwhiletheythemselvescouldn’t.(3)表示“趁着…时候”(强调主从句动作同时发生).e.g.Strikewhiletheironishot.As

侧重主从句动作同时发生，常译为①“一边…一边….”e.g.Thestudentstooknotesastheylistened.)②“随着”

e.g.Astimegoesby,wehavegainedmoreandmoreknowledge.注意

若主句谓语是短暂性动作，从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，三者可以互换！

When/While/AswewerehavinganEnglishclass,astrangerbrokein.Practice___________lwaswalkingdownthestreet，Isawsomepolicemen．_______theyheardthenews，theyweresurprised．Theyshoutedslogans____theypassedthesquare.When/While/AsWhenas二、before常见句型:Itwillbe+一段时间+before…….Itwas+一段时间+before…….Itwon’tbelongbefore……Itwasn’tlongbefore……肯定句意为“多长时间后才…”否定句意为“用不了多长时间就…”Itwillbealongtimebeforewefinishthisdictionary.我们需要很长的时间才把这部词典编译完。Itwasnotlongbeforethethiefwascaught.小偷不久就被抓住了。beforeItwillbehalfayearbeforeIcomeback.Itwon’tbehalfayearbeforewemeetagain.Wesailedfourdaysandnightsbeforewesawtheland.Wehadn’trunamilebeforehefelttired.

肯定句“才”否定句“就”itwillbe+一段时间before......多久之后才...itwon’tbe+一段时间before......不久就....1>.<2004福建卷>Scientistssayitmaybefiveorsixyears________itispossibletotestthismedicineonhumanpatients.2>.<2007江西卷>Hewastoldthatitwouldbeatleastthreemonths_________hecouldrecoverandreturntowork.3>.<2000NMET>Someonecalledmeinthemiddleofthenight,buttheyhungup_________Icouldanswerthephone.beforebefore

before三、after例：1、HecametoseemeafterIarrived.2、Immediatelyafterhewashurt,hewastakentothehospital.注：before和after引导的状语从句，主从句发生的动作先后顺序很明确，因此after从句中的谓语动词常常使用一般过去时来代替过去完成时。

Afterhe(had)finishedhishomework,Tombegantoplaycomputergames.三Since注意

since引导的时间状语从句，主句常用完成时，从句常用一般过去时。

Hehaswrittentomefrequentlysincehewasill.句型

Itis/hasbeen+一段时间+since

，如果从句是延续性动词，,用一般过去时和现在完成时不同。

Itis/hasbeentwoyearssincehewasinthearmy.

他离开军队两年了。

Itis/hasbeentwoyearssincehehasbeeninthearmy.

他当兵两年了。1>.---Howlong____theshop_____

一些表示时间的名词词组,如：themoment,eachtime,everytime,thefirsttime,theyear等,也用于引导时间状语从句，这时它们担当着连接词的功能。______________hewenttoShanghai,hepaidavisittohisformerteacher．A.ForthefirsttimeB.Thefirsttime___________lsawhim,Ithoughtofhisfather．A.ThemomentB.AtthemomentThefirsttimeThemomentEachtimehecame,hewouldbringusalotofflowers．

---DidyouremembertogiveMarythemoneyyouowedher?----Yes.Igaveittoher

__________________________________________Isawher.<2000高考>themomenttheminutetheinstantPractice1.

WheneverytimeIwasintrouble,hewouldcometohelpme.2.

Atnexttimeyoucome,dorememberbringyoursonhere.3.

ForthefirsttimeImetthegirl,Ifeltinlovewithher.4.

Youarewelcometocomebackatanytimeyouwantto.5.

AtthelasttimeshesawJames,hewaslyinginbed.语法规则：

everytime,eachtime,nexttime,thefirsttime,anytime等名词短语引导状语从句不加介词。关连词组hardly/scarcely…whennosooner…thanassoonas三种句子结构表示“一……就……”。注意：

时态

assoonas以一般时态代替将来时态

nosooner,hardly,scarcely后的句子用过去完成时，than/when后的句子用一般过去时。

倒装当hardly或nosooner位于句首时，要倒装。

五、一…就…

我一到达上海就给你打电话。时态要求：改错:Ihardlygothomewhenitbegantorain

时态要求：IwillcallyouassoonasIarriveinShanghai.ˆhad以一般现在时代替将来时主句用haddone,从句用didnosooner...than,hardly...when,scarcely...whenHehadhardlyarrivedwhenitbegantosnow．Hardly_____________whenitbegantosnow．Wehadhardlywalkedintothehallwhenthelecturestarted．Hardly_______walkedintothehallwhenthelecturestarted．_______________shegonetosleepthanthetelephonerangoncemore．_______________theboyreachedthedoorthanhecameback．hadhearrivedhadweNosoonerhadNosoonerhad倒装

六、until/tilluntil/till“直到……止”(肯定句，主句是延续性动词);

I’llwaiteuntil/tilltheconcertisover(till不能放在句首，但是until了的位置不受限制)not…until“直到……才”

hedidn’tleavetheofficeuntilhefinishedthetask.注意：倒装句、强调句，及位于句首时，只能用until。

NotuntilIreturneddidshefinishherhomework.ItwasnotuntilIreturnedhomethatshefinishedherhomework.1．Themeetingdidn’tstart___everyonewasthere．A.because B.until C.why D.if2．Theboy___tobed___hismothercamein.wentnot;until
