过去完成时的应用：
（1）与过去完成时连用的时间状语可以多种多样，使用它的主要依据是看其是否发生在“过去的过去”。

过去完成时与一般过去时：
（1）过去完成时表示以过去某时间为起点以前所发生的动作或存在的状态，即：过去完成时强调“过去的过去”，而一般过去时只表示以现在时间为起点以前所发生的事情或存在的状态。
如：He studied there two years ago. 他在那儿学习了两年。(离现在两年)
He said he had studied there two years ago. 他说他在那儿学习了两年。(离他说话时两年)

如：He said he went the shop and bought some food. 他说他去商店买了一些食品。
（3）两个动作相继发生，可用一般过去时；如第一个动作需要若干时间完成，用过去完成时。
