Iwassleepingwhentheearthquakestarted.Peoplewererunninginalldirectionswhilepiecesofglassandbrickswerefallingdown.

AsIwastryingtofindmywayout,Isuddenlyheardsomenoiseaboveme.Usingwhile,whenandas.1.当连接同时发生的两个延续性长动作时，常用while引导。e.g.WhileIwaswatchingTV,hewaslisteningtomusic.Milliewasreadingabookwhile

Eddiewassleeping.Task1Discussandworkouttherules.2.如果短暂性的动作是主句时，我们可以用when,while或as引导。e.g.When/while/asMilliewaswatchingTV,Andycameintotheroom.3.如果延续性的动作是主句时，我们经常用when来连接。e.g.MilliewaswatchingTVwhenAndycameintotheroom.4.如果两个短暂性的动作同时发生，我们通常用as连接。e.g.AsMilliesatdownonthesofa,Andycameintotheroom.注：当一个短暂性动作发生的同时伴随着一个延续性的动作，这时我们通常用过去进行时来表示延续性的动作，用一般过去时来表示短暂性的动作。when,while的区别Iwasreadingwhenyoucamein.Iwasreadingwhenyouweresleeping.When引导的时间状语从句，谓语是延续性的，或者短暂性的。通常用一般过去时，也可以用进行时。

whenwhile的区别MymotherwaswatchingTVwhileIwasdoingmyhomework.Hewastakingashowerwhilehiswifewastalkingonthephone.

while引导的时间状语从句，谓语动词只能是延续性的，通常用进行时。Theteachercamein____studentsweretalkingnoisily.=Thestudentsweretalkingnoisily___theteachercamein.

whenwhilewhen后通常加短暂性动词，如：arrive,comein,getup,open,close,finish,begin,come,go,arrive,reach,getto,leave,move,borrow,buy,die,knock

等While后通常加延续性动词,如：live,run,stay,clean,play,hold,watch,teach,read,study,teach,eat,drink,write,dance,sing,smoke
