have been in/to have been have gone have gone to 的用法

Question

have been in/to have been have gone have gone to 怎么用？
都强调了什么，在哪里用
还有怎么区分现在完成时和过去式等形式捏

Answer 1

have been 是指去过，可能已经回来，have gone 是在去的路上或者已经去了，但还没回来。 过去式有具体表示过去的时间状语如yesterday ,last monday等，现在完成式一般与since加时间点如1990， for加时间段如two years， already和 yet等词连用，表示已经完成。

Answer 2

have been to 是已经去过了的意思
比如：I've been to China 我去过中国了
have gone to 是已经去了，但是人还在那里没回来
Dad have gone to China on business 爸爸已经去中国出差了
have been in 是已经呆过一段时间 ，现在还在是一种持续的
I have been in shanghai for ten years since I was a little girl
