have been in与 have been to

have been in 其实是用了延续性动词之后的变化[arrive in /get to / reach相对应的延续性动词是be in],所以有时间段之类的词时要用它；have been to 表示某人曾经去过某地,现在在本地,一般与短暂性动词搭配have gone to 表示某人去了某地或在去某地的路上,现在不在本地,也是与 短暂性动词搭配如：1、He has been in shanghai for about three years。(他到上海已经三年了)2、He has been to shanghai three times。（他曾经去过三次上海)3、---It must be lilei。那肯定是李磊---It can't be lilei,He has gone to shanghai。那肯定不是李磊,他已经去了上海。
