3、g my homework then . 那时，我正在做作业。用法：1）过去进行时表现过去某一时刻正在进行的动作。e.g. She was writing a letter when I came in .我进来时，她正在写封信。2）过去进行时还表示过去某阶段正在进行的动作。e.g. They were waiting for you yesterday .他们昨天一直在等你。过去进行时与一般过去时的区别；过去进行时：表示正在进行的动作。I was reading a novel last night.昨晚我在看小说。（可能还没有看完）一般过去时：表示一个完成的动作。I read a nove
