过去完成时与现在完成时的区别 过去完成时强调在过去某时间或过去某动作之前，即过 去的过去。 (1)按时间状语区分，比较： by then/yesterday/last month等过去时间 +过去完成时 by now + 现在完成时 （by now = so far）
by the end of + last month/year等过去时间+过去完成时 by the end of + this month/year等现在时间+现在完成 时
本课重点：
· 动词过去分词规则极不规则变化
· 过去完成时用法
· 有时间状语提示词
· 无时间状语提示词
· 过去完成时与现在完成时的区别
· 过去完成时与一般过去时的区别
过去分词的构成： 1. 规则动词的变化：
过去完成时的构成：由助动词 had + 动词的过去分词（done)
a) 一般情况下在动词后面加 ed work ------ worked play -------- played b) 以 e 结尾的动词直接加 d use ------ used refuse ------ refused c) 以辅音字母加 y 结尾的动词，把 y 改 i 再加 ed study ----- studied carry ----- carried d) 以重读闭音节结尾的，前面有单个元音字母时， 双写辅音字母，再加 ed drop ------- dropped stop ---- stopped 2. 不规则动词的变化见课本 附录

一般过去时常见标志词：Fra Baidu bibliotek
比较：
He had been a student for 8 years by the time he was sixteen.

(2)按是否体现某动作在另一过去动作 之前发生区分：
