改错:1、Many years ago, Jim had lived

改错:1、Many years ago, Jim had lived in Paris with his uncle for a long time.

Answer 1

1、Many years ago, Jim lived in Paris with his uncle 或者

2、Since Many years ago, Jim had lived in Paris with his uncle for a long time.
many years ago 是时间点，后面又是for a long time 是时间段，主语用过去式或者过去完成时都存在矛盾，不太合适，所以要改。

Answer 2

Many years ago,Jim had lived in Paris with his uncle for a long time.这个句子是正确的

Answer 3

Many years ago, Jim lived in Paris with his uncle for a long time.
