I was doing my homework at this time yesterday.昨天的这个时候我正在做作业。
They were waiting for you yesterday.他们昨天一直在等你。
过去进行时的构成：
肯定形式：主语+was/were+V-ing
否定形式：主语+was not (wasn't)/were not (weren't)+V-ing
疑问形式：Was/Were+主语+V-ing。
基本用法：
1.过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有，at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…)，when sb. did sth等时间状语从句，如：
