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

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

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

have been to 去过。。。已经离开那里。或者回来，或者又去了其他地方 have gone to去了.... 已经离开原地,或者到达...,或者在半路上 have been in一直在....例如they have been in chicago

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