2、then.到那时为止我已经学会了 1000 个英语单词。 Im sorry to keep you waiting. 对不起，让你久等了。 Oh, not at all. I have been here only a few minutes.没什么，我只等了几分钟。(“等”的动作从过去某一时间点持续到现在)二、过去完成时与一般过去时的区别虽然这两种时态都表示过去发生的动作或存在的状态，但在使用时应注意以下几点：1. 时间状语不同：过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。比较：They had arrived at the station by ten ye

3、sterday.They arrived at the station at ten yesterday.2. 在没有明确的过去时间状语作标志时，谓语动词动作发生的时间先后须依据上下文来判断：先发生的用过去完成时，后发生的则用一般过去时。She was very happy. Her whole family were pleased with her, too.She had just won the first in the composition competition.3. 当两个或两个以上接连发生的动作用 and 或 but 连接时，按时间顺序，只需用一般过去时来代替过去完成时;另外

4、，在 before ， after ， as soon as 引导的从句中，由于这些连词本身已经表示出时间的先后，因此也可以用过去时来代替过去完成时。He entered the room, turned on the light and read an eveningpaper.
