英语语法问题
1.Mr.zhang,who is said to have gone t the USA to live with his son after retirement,(taught) at our school for twenty years
2.susan,how fluently you speak french!
thanks,i (had studied) french for two years before i came to this company请问这两个句子有什么不同吗?为什么第一个用过去式第二个用完成时呢?

Answer 1

1 Mr.Zhang,who is said to have gone to the USA to live with his son after retirement,(taught) at our school for twenty years.
中间是定语从句,修饰Mr. Zhang,可以看出张老师现在已经不再教书了,退休了

动作已经结束,典型的一般过去式用法

2 I (had studied) french for two years before i came to this company.
在来到公司前,学习过法语

过去的过去,典型的过去完成时用法
