过去完成进行时用法介绍 过去完成进行时 形式： I （or You，He，John，They，Those men） had been studying． 770 过去完成进行时与过去完成时的用法很相近，它通常表示一个持续到过去某时的动作： He had been waiting for two weeks． He was still waiting．（有一个表示一段时间的状语） Up to that time he had been translating those books．（He was still translating at “that time”．） He had been writing the letter till two oclock． He was now thirty years old．He had been gambling since he was ten．（He was still gambling at thirty．） He had been standing there in the sun．（没有时间状语） He had been thinking about his marriage． 不过这个时态并不一定表示这个过去动作将持续下去： He came back at seven．He had been waiting for her two hours．（At seven he did not wait any more．） He stopped swimming．He had been swimming for the last three hours． 另一方面，这个时态也和现在完成进行时一样，也可有一些特别的含义： 1）尚未完成： He had been writing the novel．（He had not finished it yet． 完) 有些动词(如rain, snow, cough, work等)本身并不表示动作完成，这时用两种时态都可以，且含义区别不大： It rained [was raining] all day yesterday. 昨天下了一天的雨。 过去进行时用法复习　核心提示：■构成方法过去进行时由“was [were]+现在分词”构成。■基本用法主要表示过去某一时间正在进行的动作：He fell asleep when he was reading. 他看书时睡着了。We were expecting you yesterday. 我们昨天一直在等你。He was pl... ■基本用法 主要表示过去某一时间正在进行的动作： He fell asleep when he was reading. 他看书时睡着了。 We were expecting you yesterday. 我们昨天一直在等你。 He was playing while I was studying. 我在做功课时他在玩。 与现在进行时相似，过去进行时也可表示称赞、惊讶、厌恶等感情色彩，如： They were always quarrelling. 他们老是吵架。 ■与一般过去时的区别 过去进行时通常表示一个过去正在进行且尚未完成的动作，而一般过去时则通常表示一个过去已经完成的动作： I was reading a book last night. 我昨晚在看书。(不一定看完) I read a book last night. 我昨晚看了一本书。(已经看完) 有些动词(如rain, snow, cough, work等)本身并不表示动作完成，这时用两种时态都可以，且含义区别不大： It rained [was raining] all day yesterday. 昨天下了一天的雨。 过去进行时专项练习 一、单项选择 1.My brother ___ while he ___ his bicycle and hurt himself.
