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.(刚要……这时突然……)when…3.还可以表示原因“既然”，相当于since;consideringthat。如：Itwasfoolishofyoutotakeataxiwhenyoucouldeasilywalkthereinfiveminutes.

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/Whilehewaseatinghisbreakfast,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.

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.

till,until和not…until小结：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.
