请帮我看一下这句话有错吗.After working happily with him so many years ,he is more than a friend of mine.
这是一道用括号中的词的翻译题。
原文是：在和他愉快的工作那么多年后，他不仅仅是我的朋友。（more than）

有错
两个句子的主语不一致
After working happily with him so many years
这部分的主语应该和主句的主语一致,是he
可是,with him ,he with him?不通啊
要调整一下宾语 him---me
看了你的补充提问,我觉得既然主从句的主语不一致,就不适合用after doing 来表达,老老实实用时间状语从句
after i had woked happily with him( for )so many years,he was more than a friend of mine.
再问： 我主要是想问一下a friend of mine对不对....
再答： 那是百分之百对的 双重所有格，后面用名词性物主代词 新概念1册上就有此种语法的例句
再问： 嗯，我懂了~
