Whether it is true remains a question. 它是不是真的还是个问题。 2. 与不定式连用时。

过去完成进行时与过去完成时

1. 构成:

过去完成进行时:had been doing

过去完成时:had done

2. 与一段时间连用时,过去完成进行时和过去完成时都可以表示一个动作从过去某时或在过去某个动作前开始,并可能延续下去。两种结构可以互换,但过去完成进行时更强调动作的持续性和未完成性。比较:

我到这里前,我弟弟已经在这家工厂工作了三年。

Before I arrived here, my brother had worked in the factory for three years. (表示已经完成)

Before I arrived here, my brother had been working in the factory for three years. (强调“一直在这家工厂工作了三年,中间没有间隔”) 3. 没有与一段时间连用时,区别较大:

1)过去完成进行时表示动作在过去某时或过去某动作时仍在进行。 2)过去完成时则表示动作到过去某时或某动作时已经结束。 比较:

He said they had prepared for the meeting. 他说他们已经为会议做好了准备。 (prepare的动作到say动作发生时已经完成)

He said they had been preparing for the meeting. 他说他们一直在为会议做准备。 (prepare的动作一直在进行,且有可能持续下去)
