● have been to和have gone to的区别：
have been to 强调“去过”，现已不在那里，如：
He has been to the USA three times.
他(曾经)到美国去过三次。(他人生中有过这样的经历，过去“到过美国”，现在已“不在美国了”)
He has gone to the USA. 他已经去美国了。(主要强调的是“去了”，也许刚动身出发，也许已经到了，也许还在路上，总之现在人不在说话的现场。)
Presentation Sentences
● have been to 和have been in的区别
　 have been to强调人“已回到原地”，后面可接表示“次数”的状语。例：
She has been to Shanghai only once. 她只去过一次上海。
— How many times has he been to Shanghai
他去过几次上海？
— He's been there many times. 他去过很多次。
have been in表示某人“已在某地停留一段时间，现仍在那里”，其后常带表示一段时间的状语。例：

一般疑问句： Have (Has ) + 主语+ 过去分词 +其他
否定句：主语+ have(has)+ not +过去分词 +其他.
用法 与不确定的副词相连。如：just, already, yet, once, twice, ever, never等。 当有表示一段时间的词汇for 或since时，要与延续性动词相连。 have been to, have gone to, have been in 词的区别。
