Question

have gone to/have been/have been in/have been to/have been

Answer 1

　have been/have been in/have been to/have gone to
have been意为“成为……多长时间”；have been in意为“在某地呆了多长时间”。二者都常与表示一段时间的状语连用。如：
1、She has been a teacher for five years。
2、I have been here for two hours。
3、His parents have been in China for three months。
have been to意为“曾经去过某地”，现在已不在那里了，常与ever,just,never等词连用。其后可接once,twice等表示次数的词。如：
4、He has just been to the library。
5、They have never been to the Great Wall。
6、I have been to Beijing many times。
have gone to意为“到某地去了”，说话时作句子主语的人不在现场，通常是第三人称作句子的主语。如：
7、Whereis Tom? He has gone to the post office。
8、Mr Green isnt here。He has gone to Shanghai。
