2. 一般过去时与过去进行时的用法比较
(1) 一般过去时表示在过去某时发生过的动作或存在的状态，侧重动作已完成；而过去进行时可以表示过去某个时间正在进行的动作，强调动作在持续，并未完成。
Last year, he wrote a book.
Last year, he was writing a book, but hasn’t finished till now.
(2) 一般过去时和过去进行时同时出现在句中，表示一个动作发生在另一个动作进行的过程之中时，通常表示较短的动作用一般过去时，表示较长的动作用过去进行时。其中一个在由when或while引导的时间状语从句中。

I was running downstairs when I slipped and fell.

3. 现在完成时与一般过去时的用法比较
一般过去时只单纯表示过去发生过的动作或存在的状态，与现在时间没有联系，可和表示确切过去的时间、地点状语连用。现在完成时表示过去发生过的某动作对现在造成的影响或结果，强调现在的情况，不能和表示确切的过去时间、地点状语连用。

Last week she promised to help me.
(2) He has been caught by the police.

(3) Mr. Black has lived in China for ten years.

4. 过去完成时与一般过去时：
过去完成时强调的是“过去的过去”；如出现同一主语连续几个动作（“连谓”）形式则只用一般过去时即可。
