1、过去进行时（一）概念：表示过去某段时间或某一时刻正在发生或进行的行为或动作。可从两个方面来理解： ①过去某个时间正在发生的动作 例：He was cooking at six last night. 昨天晚上六点，他正在做饭。 ②过去某段时间正在发生的动作 例：IwasstayingherefromMarchtoMaylastyear. 去年从3月到5月，我一直呆在这里。（二）基本结构：was/were+doing （三）与过去进行时连用的时间状语，常见的有 at nine last night/ at that time= then
2、/ at this time yesterday /或有when the teacher came in/ while he was reading的提示 （四）过去进行时的时间状语 :when, while ①while表示一段时间，因此它所引导的状语从句中，谓语动词常用进行时态，如：When/While we were having supper, the light went out. 我们正在吃饭时灯熄灭了。②when用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。
