词

过去完成进行时表示过去某一时间之前一直进行的动作。 过去完成进行时表示动作在过去某一时间之前开始，一直延续到这一过去时间。和过去完成时一样，过去完成进行时也必须以一过去时间为前提。例如: 1.I had been looking for it for days before I found it. 这东西我找了好多天才找着的。 2.They had only been waiting for the bus a few minutes when it came. 他们只等了一会儿车就来了。 3.We had been studying this project for days before it put into effect. 这个项目我们研究了好几天才实施的。 4.We had only been waiting for the professor a few minutes when he arrived school. 我们只等了一会儿，教授就来学校了。 5.I had only been waiting for taxi a few minutes when it came. 我只等了一会儿，出租车就来了。 6.Our team had been practicing many times before we finished. 我们的团队练习了很多次才完成的。 7.The telephone had been ringing for three minutes before it was answered. 电话响了三分钟才接起来。 我们再来看看下面两个例句的区别： 1. Who's been eating my apples？ 2. Who's eaten my apples？ 第一句用过去完成进行时表示过去某一时间之前一直进行的动作。 过去完成进行时表示动作在过去某一时过去完成进行时时态表示有强烈的感情色彩，表示愤怒不满，而第二句句只是希望回答的一个问题，并没有强烈的感情色彩。再有就是，第一句兼有进行时态，所以它表示的是所有苹果未被全部吃光的意思，而第二句是完成时态，说明苹果一个不剩了。

行时表示某人的企图、意愿，例如： He had been studying the meaning of this proverb.（He was trying to study it） 他一直在研究这句谚语的意思。 3、过去完成时表示未得结果，例如： We had been studying what our enemy had said，but we were not able to understand it. 我们一直再研究我们的敌人说的话，但是，我们还是不能理解它。 4、过去完成进行时表示最近情况，例如： He had been quarreling with his wife lately. 最近，他一直和他的妻子吵架。 5、过去完成进过去完成进行时表示的是过去行时表示反复的动作，例如： He had been asking me the same question many times. 很多次，他一直问我同样的问题。 6、过去完成进行时表示人的情绪等，例如： What had he been doing？ 他一直在干嘛？

过去完成进行时与过去完成时的用法很相近，它通常表示某个过去正在进行的动作或状态，持续到过去某个时刻，还未完成行时的肯定句型是主语+had+been+doing something.例如： 1. He had been waiting for two months． 他已经等了两个月了。 2. Up to that time he had been reading those books． 直到那时他一直在读这些书。 3. He had been doing homework till ten o'clock． 他一直在写功课到十点钟。 4. He had been smoking since he was sixteen． 他从十六岁开始就一直吸烟。 5.
