最好是把用法详细说一下 。有例子最好
have been to可持续的
如：they have been there for 4 years.
have gone to瞬者亩间的首嫌森者衫
如：they have gone to American
前者去过但回来了
后者去了还没有回来
have been to 是已经去盯薯罩过了的意思
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凯闹
Dad have gone to China on business 爸爸已经去中国出差了
have been in 是已经呆过一手念段时间 ，现在还在是一种持续的
I have been in shanghai for ten years since I was a little girl
很容易分辨的：
have been to+次数
have gone to（还没回来） 【携键注猛隐行：不能+for】枝哗
附：have been in+for（一段时间）
have been to是去过某地
例如：I have been to shanghai 我迟扒去过
上海have gone to是去某地，可能已带旦升经到了，也蠢老可能在路上还没到
例如：she has gone to school 她去学校了（可能没到，也可能到了）
