He said that he went home very late every day. ------ 同时发生（一般过去时态）
2．He said that he would go to America the next day.-----之后发生（过去将来时态）
3．He said that he had seen the film. ------ 之前发生（过去完成时态）
张国际二、由when引导的时间状语从句的复合句的时态判定：
I. 当两个过去动作有明显的先后时，先发生的用过去完成时态，后发生的用一般过去时态。
When I got home, my mother had finished cooking.
Got 后发生------一般过去时态
Had finished ------ 过去完成时态
II.当两个过去动作同时发生，出现下面三种时态情况：
1.When I got home, my mother was cooking.
Got home: 强调动作的结果或事实（瞬间）解释为：‘…….的…….了’----一般过去时态
Was cooking:强调动作的过程（持续）解释为：‘正在’-----过去进行时态
2.When I got home, I saw a letter on the ground.
Got home: 强调动作的结果或事实（瞬间）解释为：‘…….的…….了’----一般过去时态
Saw: 强调动作的结果或事实（瞬间）解释为：‘…….的…….了’----一般过去时态
3.When I was doing my homework, my father was reading a newspaper.
Was doing: :强调动作的过程（持续）解释为：‘正在’-----过去进行时态
Was reading: :强调动作的过程（持续）解释为：‘正在’-----过去进行时态
III.当出现两个将来动作时，时间状语从句用一般现在时态代替一般将来时态，主句仍用一般将来时态（主将从现）
(When my father gets home tomorrow), he will give me a birthday present.
(After I leave my high school), I will go on to college.
= I won’t go to college (until I leave my high school )
(If it doesn’t rain tomorrow), we will play basketball.
三、by +过去时间修饰一个过去完成时态：(by = before)

By the time I got to Shanghai, I had lived in the country.
四、有前后文的时态判定：
