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)延續(xù)性動詞

e.g.WhenIwasyoung,Ilikeddancing.(2)瞬間性動詞(不能用while）

e.g.Itwassnowingwhenwegottotheairport．

(3)表示“這時”“正在這時候”

e.g.Iwaswalkingonthestreetwhensuddenlysomeonepattedmeontheshoulder.(4)主從句動作先后發(fā)生(不能用while）

e.g.WhenIgottothecinema,thefilmhadalreadybegun.While+(1)延續(xù)性動詞

e.g.WhileIslept,athiefbrokein.(2)表示兩種情況對比，“然而”“而”

e.g.Theyweresurprisedthatachildshouldworkouttheproblemwhiletheythemselvescouldn’t.(3)表示“趁著…時候”(強(qiáng)調(diào)主從句動作同時發(fā)生).e.g.Strikewhiletheironishot.As

側(cè)重主從句動作同時發(fā)生，常譯為①“一邊…一邊….”e.g.Thestudentstooknotesastheylistened.)②“隨著”

e.g.Astimegoesby,wehavegainedmoreandmoreknowledge.注意

若主句謂語是短暫性動作，從句用延續(xù)性動詞的進(jìn)行時態(tài)表示在一段時間內(nèi)正在進(jìn)行的動作時，三者可以互換！

When/While/AswewerehavinganEnglishclass,astrangerbrokein.Practice___________lwaswalkingdownthestreet，Isawsomepolicemen．_______theyheardthenews，theyweresurprised．Theyshoutedslogans____theypassedthesquare.When/While/AsWhenas二、before常見句型:Itwillbe+一段時間+before…….Itwas+一段時間+before…….Itwon’tbelongbefore……Itwasn’tlongbefore……肯定句意為“多長時間后才…”否定句意為“用不了多長時間就…”Itwillbealongtimebeforewefinishthisdictionary.我們需要很長的時間才把這部詞典編譯完。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+一段時間before......多久之后才...itwon’tbe+一段時間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引導(dǎo)的狀語從句，主從句發(fā)生的動作先后順序很明確，因此after從句中的謂語動詞常常使用一般過去時來代替過去完成時。

Afterhe(had)finishedhishomework,Tombegantoplaycomputergames.三Since注意

since引導(dǎo)的時間狀語從句，主句常用完成時，從句常用一般過去時。

Hehaswrittentomefrequentlysincehewasill.句型

Itis/hasbeen+一段時間+since

，如果從句是延續(xù)性動詞，,用一般過去時和現(xiàn)在完成時不同。

Itis/hasbeentwoyearssincehewasinthearmy.

他離開軍隊兩年了。

Itis/hasbeentwoyearssincehehasbeeninthearmy.

他當(dāng)兵兩年了。1>.---Howlong____theshop_____

一些表示時間的名詞詞組,如：themoment,eachtime,everytime,thefirsttime,theyear等,也用于引導(dǎo)時間狀語從句，這時它們擔(dān)當(dāng)著連接詞的功能。______________hewenttoShanghai,hepaidavisittohisformerteacher．A.ForthefirsttimeB.Thefirsttime___________lsawhim,Ithoughtofhisfather．A.ThemomentB.AtthemomentThefirsttimeThemomentEachtimehecame,hewouldbringusalotofflowers．

Atnexttimeyoucome,dorememberbringyoursonhere.3.

ForthefirsttimeImetthegirl,Ifeltinlovewithher.4.

Youarewelcometocomebackatanytimeyouwantto.5.

AtthelasttimeshesawJames,hewaslyinginbed.語法規(guī)則：

everytime,eachtime,nexttime,thefirsttime,anytime等名詞短語引導(dǎo)狀語從句不加介詞。關(guān)連詞組hardly/scarcely…whennosooner…thanassoonas三種句子結(jié)構(gòu)表示“一……就……”。注意：

時態(tài)

assoonas以一般時態(tài)代替將來時態(tài)

nosooner,hardly,scarcely后的句子用過去完成時，than/when后的句子用一般過去時。

倒裝當(dāng)hardly或nosooner位于句首時，要倒裝。

五、一…就…

我一到達(dá)上海就給你打電話。時態(tài)要求：改錯:Ihardlygothomewhenitbegantorain

時態(tài)要求：IwillcallyouassoonasIarriveinShanghai.?had以一般現(xiàn)在時代替將來時主句用haddone,從句用didnosooner...than,hardly...when,scarcely...whenHehadhardlyarrivedwhenitbegantosnow．Hardly_____________whenitbegantosnow．Wehadhardlywalkedintothehallwhenthelecturestarted．Hardly_______walkedintothehallwhenthelecturestarted．_______________shegonetosleepthanthetelephonerangoncemore．_______________theboyreachedthedoorthanhecameback．hadhearrivedhadweNosoonerhadNosoonerhad倒裝

六、until/tilluntil/till“直到……止”(肯定句，主句是延續(xù)性動詞);

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：倒裝句、強(qiáng)調(diào)句，及位于句首時，只能用until。

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