I have been to the Disneyland twice.为什么been不用gone

have been to 去哪现在已经回来
have gone to 去哪现在还没回来。
都用在现在完成时态当中。
例如： I have been to Dalian four times
我去大连四次了（说明现在已回来）
He has gone to Dalian , he will be back in two days.
他已经去大连了，两天后回来。（去还没有回来）

have been指去过，已经回来了说这件事。have gone是去了还没回来

have been to someplace 意思是去过某地，现在不在那儿；
have gone to someplace 意思是到了某地，现在还没回来~
初中时老师就是这么教的~~
