在有直接影响并且还在进行的动作。 例如： He had been waiting for two weeks. He was still waiting.（有一个表示一段时间的状语） She had been suffering from a bad cold when she took the exam.她在考试之前一直患重感冒。 不过这个时态并不一定表示这个过去动作将持续下去： 例如： She came back at six. She had been waiting for him three hours.（六点时她已经没有再等了） 而过去完成时（The Past Perfect Tense）表示过去某一时间或动作以前已经发生或完成对过去的某一点造成的某种影响或是结果。它表示动作发生的时间是“过去的过去”，侧重事情的结果。 例如： I had finished reading the book by ten o'clock last night到昨晚10点钟，我已经读过去完成进行完了这本书。 要想完全掌握这两种时态，需得经过大量的练习，读完这篇文章，请同学们赶紧拿起笔来，多多练习，争取能正确合理地使用这两种时态！

I had been watching TV before you called me. 2. I had been

我们学习的英语时态有很多，有的简单明了，但是有的时态却非常抽象，通常不是直接使用而是放在间接引语或虚拟语气中，过去完成进行时就是一例。过去完成进行时，就是相对过去的某个时刻来说已经对现在有直接影响并且还在进行的动作。放在间接引语或虚拟语气中时它的时态不能再向前推，向后推是现在完成进行时。 过去完成进过去完成进行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一直持续到之后的当前才结束。例如： 1.He had been waiting for two weeks. (He was still waiting) 他已经等了两个星期了。 2.Up

行时的用法 A. 在某段时间内一直进行的动作用现在完成进行时来强调动作在某段时间里的持续性动作通常有"现在"的结果要根据上下文来确定到"现在"为止动作是否还在继续进行同样过去完成进行时表示在过去更早时间内进行的动作,并对过去某一时刻产生结果。 B.表示重复动作的现在/过去完成进行时 我们也可以用完成进过去完成行时形式来表示现在或过去经常重复的动作。 注意过去完成进行时和过去完成时类似需要有过去这一时间点。

行时主要表示过去某时的一个动作正在进行。例如： 1. I was writing a letter when she came to see me. 当她来看我时我正在写信。 2.I had been writing a letter for two hours by the time she came to see me. 当她来看我的时候，我已经写了两个小时的信了。 5. 过去完成进过去完成进行时是一种比较抽象的时态，学习它需要理解整个句子所处的语境和时间。过去完成进行行时与过去完成时的不同。过去完成时表示过去某时间前已经发生的动作或情况，这个过去的时间可以用by，before等介词短语或一个时间状语从句来表示；或者表示一个动作在另一个过去动作之前已经完成。例如： 1. They had just had breakfast when Tom came in. 汤姆来时，他们刚吃过早饭。 2. They had been having breakfast for ten minutes when Tom came in. 汤姆来时，他们已经吃了十分钟的早饭了。

行时之后也可接具有"突然"之意的when分句。 二、将来完成时的用法有以下几点： 1、构成：will/shall have +过去分词 1）We hope it will have stopped raining before we set off for the picnic. 我们希望在出发去野餐以前雨就已经停了。 2）I'll have done all the work by the time you are back this evening. 你们今晚回来的时候我就将做完所过去完成进行时容易和将来完成时混淆，从而导致在考试中把时态选错，造成有的工作了。 2、用法： 1. 表示在将来某一时刻将完成或在另一个未来的动作发生之前已经完成的动作。注意：常与将来完成时连用的时间状语有： by (the time / the end of ) + 表示将来时间的短语和句子； before (the end of ) + 表示将来时间的词语或句子； when, after等加上表示将来动作的句子等。 例如： 1）By the year 2050, scientists probably will have discovered a cure for cancer. 到2050年，科学家们可能已经找到治愈

过去完成进行时由“had been +现在分词”构成。它的用法是表示从过去某一时间开始一直延续到另外一个过去在这所学校教书已经10年了. 10.He has done a lot of work in the past two years. since 在现在完成时中意为自...以后自...以来，时间状语常用since加一个过去的时间点或for加一段时间或by加一个现在时间。 如果不是时间点 也不是时间段 还有什么别的时间啊  具体情况具体对待吧 最好会翻译句子的意思 在适当的选择for和since 比如说 1. He has had a house since 2005.   他自从2005年以来就拥有了一套房子.        2. The play cat has been on for half an hour. 短剧《猫》已经开演半个小时了.
