小学英语必考的知识点归纳1
一、现在完成进行
现在完成进行时主要用于：表示过去开始的某一动作一直持续到现在，以至延伸到将来，它强调动作延续时间之长久。
e.g. I`ve been writing an article. 我一直在写一篇文章。(还在写)
cf. I`ve written an article. 我写了一篇文章。(已写完)
It has been raining these days. 这些天一直在下雨。
二、过去完成时
1 、过去完成时是一个相对时态，表示过去的过去，只有在两个过去发生的动作相比较时才可显示出来。
e.g. As soon as we got to the station, the train had left.
注：主从句表达的动作紧接时，即两动作发生的时间没有明显时间上的悬殊或空档时，主从句都可用一般过去时。
e.g. Where did your brother study before he joined the army? 2 、过去完成时可表示截止过去某一时间动作的总或动作的结束。
e.g. By the end of last month. We had reviewed four books
By eight o`clock, he had finished his homework.
与这个时态连用的时间状语常有：
by 1985, by eight o`clock, by then, by the end of last month, by the time when, when, as soon as, before 等连词引导的时间状语从句，表示主句动作结束的时间。
