第一部分  考点梳理

            八、过去进行时

            1. 含义:过去某个时间正在进行的动作。
            常考的时间状语:when与while+一般过去时。

            易错点:①at that time/moment
            ②at this time+过去时间(at this time yesterday)

            ③at+具体时刻+过去(at two last Sunday)
            ④过去时间段(from five to six last night)
            2. 结构:主语+was/were+动词-ing形式

            易混点:过去进行时和现在进行时动词变化规律相同。
            口诀:①一动加-ing;②见e去e加-ing;③遇ie变y加-ing;④重读辅与辅双写尾字母加-ing。
            eg: I              in the street when (时间状语) someone called (一般过去时) me.

            当有人打电话给我时,我正在街上散步。
            A. walk                B. walked              C. have walked        D. was walking

            解析:walk(一般现在时)、walked(一般过去时)、have walked(现在完成时)、was walking(过去进
            行时),故选D。
