    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.

    面的句子试比较: It had rained yesterday. (误) It rained yesterday.(正) 或许你会说:“昨天下了雨,可是今天已放晴了,下雨已是过去的事,而且已经下完了,所以就用过去完成时……。”这就是最令同学们对一般过去时和过去完成时感到混淆和困惑的。实际上只要我们了解下面的两点原则就可以消除这种现象。 1. 由过去的时过去完成时(The Past Perfect Tense):表示过去某一时间或动作以前已经发生或完成了的动作,对过去的某一点造成间作状语来修饰动词的句子都使用一般过去时。 2. 除非从谈话的先后关系和上下文关系对过去的动作完成的基准点可以确定以外,应该避免在简单句中使用过去完成时。
