2)过去完成时动词可以表示过去某一时刻之前发生的动作或呈现的状态，这一动作一直持续到过去这一时刻或将继续下去。例如：

3)过去完成时动词常用于间接引语和虚拟语气，我们以后会详细讲述。
4)此外，过去完成时常用于 no sooner…than… 和 hardly(scarcely) …when… 这两个句型，前面部分用过去完成时，后面部分用一般过去时。例如：
No sooner had he stolen the purse than he was caught red-handed. = He had no sooner stolen the purse than he was caught red-handed. 他刚偷到钱包就被当场抓获。
Saddam had hardly realized what was happening when he was captured. = Hardly had Saddam realized what was happening when he was captured. 萨达姆还没有意识到在发生什么事情就被抓获了。
翻译练习：

3)他曾告诉过我，会议两点钟开。可是当我到了以后，我还得等到两点半。

4)他在这里住了两三天，才觉得没有什么拘束(feel at home)。

8、过去完成进行时
(1)形式：had been + 动词的现在分词。
(2)用法：表示一直持续到过去某个时间的行为动作，此行为动作或刚结束、或还没结束(可以从上下文看出)。这一时态经常与一般过去时一起使用。例如：
