has been to 与has gone to的区别

1)have/has gone to 表示去了,属于瞬间动词(暂短性 动词),不与一段时间连用.
eg:-Where is Tom?
-He has gone to Shanghai.(他去了上海)言外 之意:他不在说话现场
如果表示去过则用has / have been to
eg:I have been to the Great Wall.(我去过长城)
另外,如果时间状语是一段时间,也用has / have been to
eg:he has been there for two years.(两年是时间段所以用been)
(2)同样,has /have been away 和 has/have left 是对应的,都表示离开,has/have been away 是延续性的,与时间段连用,has/ have left 是瞬间动词
eg :He has been away from that factory for two days.(离开两天了)
eg:He has left from his office.(只表示离开)
