AdverbialClauses状语从句在复合句中,如作状语的是一个从句,该从句被称为状语从句。作什么样的状语就叫什么类型的状语从句,状语从句可以表示时间、地点、原因、条件、目的、结果、让步、比较和方式等。用从句来表达一件事情或一个行为发生的时间,这个从句就叫做时间状语从句。

时间状语从句beforebythetimeaftertill/untilwhen/while/aswhenevereachtimethemomentoncedirectlyassoonasinstantlyhardly…whenimmediatelyNosooner…thanscarcely…when(一……就……)常用引导词

引导词when释义when既可以表示在某一时间点发生的事,又可以表示在某一时间段发生同时发生也可以的事。例句Whentheweatherisfine,manypeoplegooutforawalk.引导词while释义在该类状语从句中,主句行为在从句行为进行的过程中发生。（while从句表示持续的行为,从句中要用持续性动词或状态动词,且持续性动词常用进行时态。例句DonotmakeanynoisewhileIamrecording.引导词as释义强调两动作同时进行,有对比含义。例句Asshewalkedalongthestreet,shesanghappily.

很多时间状语从句,都是连词引起的：Whenwelivedintownweoftenwenttothetheatre.Aftershegotmarried,shechangedcompletely.Wemuststrikewhiletheironishot.ItwasalongtimebeforeIgottosleepagain.Asthesunrosethefogdispersed.Tellhimassoonashearrives.

也有些时间状语从句不由连词引起：Nowthatwehavedecoratedthehouse,wecanmovein.Icameimmediatelyyoucalled.ThemomentIsawhimIknewthattherewasnohope.Ihadnosoonercheckedintothehotelthanhearrived.Hardlyhadhearrivedwhenshestartedcomplaining.
