四、过去完成时

1. 含义：过去不影响现在（两过：过去的过去）。
常考的时间状语：before + 过去时；when + 过去时；by + 过去时（by the end of last year/term/month)。
2. 结构：主+had+PP（PP表示动词的过去分词）
eg: My mother said (过去式) she (过去完成时) the math book already.

我妈妈说她已经读过这本数学书了。
A. has read B. reads C. will read D. had read
解析：said是过去式，读是说之前发生的动作，故用过去完成时。has read是现在完成时，reads是一般现
在时，will read是一般将来时，had read是过去完成时，所以选D。
