(从句动词可延续也可非延续)IwasthinwhenIwasachild.Thefilmhadbeenonwhenwearrived.When的用法2.beabouttodo… when…bedoing… when…beonone’sway… when…beonthepointofdoing… when…hadjustdone… when…以上句式中的“when”译为“这时或那时”不可以用其它连词替换。

1.必须引导持续性动作，强调在一段时间内，主句和从句动作同时发生。MymotherwascookingwhileIwasdoingmyhomework.Pleasedon’ttalksoloudwhileothersareworking.

While的用法2.“然而”表示对比。IlikewatchingTVwhilehelikesreading.

3.引导让步状语从句“虽然、尽管”WhileIadmithisgoodpoints,Icanseehisshortcomings.尽管我承认他的优点，但我还是看到了他的缺点。4.引导条件状语从句“只要”Whilewearehere,don’tworry.2.“然而”表示对比。3.引导让步状语从句As的引导时间状语从句的用法“随着”“一边…一边…”“当…”强调动作同时发生，无先后As的引导时间状语从句的用法.1.AsIgetolder,Igetmoreoptimistic.随着年龄的增长，我变得更加乐观。2.Hehurriedhome,lookingbehindashewent.他匆匆忙忙回家，边走边往后看。3.Ashewasgoingout,itbegantorain.当他出去时开始下雨了。.“as”可以引导的其它状语从句：Youngasheis,heknowsalot.

（让步）Ashewasn’treadyintime,wewentwithouthim.

（原因）DoasItoldyou./doasyoulike.

（方式）HeisasoldasI/me.

（比较）“as”可以引导的其它状语从句：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，也可以是非延续的动词。如：When/Whilehewaseatinghisbreakfast,heheardthedoorbellring.WhenIstoppedmycar,amancameuptome.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…,一边…一边”，连词用as.如：Astheelectionapproached,theviolencegotworse.4．如果主句谓动是非延续性的，而从句谓动是延续性动词并使用进行时态时，when,while与as可互换使用。如：When/While/AsIwaswalkingdownthestreet,Icameacrossanoldfriendofmine.连接词when,while,as的用法区别：Before的多种翻译方式：在…之前2.在It+be+短时间+before句型中主句是肯定句式时：“（多久之后）才…”

主句是否定句式时：“（过不了多久）就…”3.“还没来得及，就…”4.“趁……”Before的多种翻译方式：Beforetheygottothebusstop,thebushadgone.在..之前Itwillbe5years

before

hereturnstohismotherland.多久之后才…Wewaitedalongtime

－Herushedoutoftheroom____Icouldsayaword.A.beforeB.until C.when D.afterCCA1.Hemadeamistake,butthetill,until和not…until：1.主句是肯定句时，主句的动词必是延续性动词，表示“主句动作或状态一直持续到从句动词发生才停止”。从句引导词是till/until都行。如：

Wewaiteduntil/tillhecame.2．主句是否定句时，主句谓语动词是非延续性动词，表示“主句动作直到从句动词发生才开始”，从句引导词通常用until。如：

Hewon’tgotobeduntilshereturns.3．till不可以置于句首，而until可以。如：
