When和While引导的时间状语从句共同点不同点when都可以引导时间状语从句，意为“当......的时候”引导时间状语从句时，既可以表示时间点，也可以表示时间段；从句中的谓语动词既可以是非延续性动词，也可以是延续性动词.（多用于过去时态）while引导时间状语从句时，从句只表示时间段；从句中的谓语动词必须用延续性动词。（多用于进行时态）Enrichyourlifetoday,yesterdayisowismystery1.基本概念过去进行时表示在过去某一时刻或一段时间内正在进行的动作。这一特定的过去时间除有上下文暗示以外,一般用时间状语来表示。2.结构

3.句式(以work为例)疑问式和简略回答:WasIworking?Yes,youwere.No,youwerenot/weren’t.Wereyouworking?Yes,Iwas.No,Iwasnot/wasn’t.注：1)wasnot常缩略为wasn’t;werenot常缩略为weren’t。2)一般过去时与过去进行时用法的比较:一般过去时表示在过去某个时间发生过的动作或存在的状态,而过去进行时则表示在过去某一时刻或某一段时间正在进行的动作。Lookatthetableandwritesentenceswithbothwhileandwhen.JohnMarytakephotosbuyadrinkplaythepianoleavethehousecleanhisroomturnontheradioshoptakethecartothecar
