have been to, have gone to与have been in
have been to 表示“曾经到过某地”（现在已经回来）；have gone to表示“到某地去了”（还没回来，可能已经到达目的地，也可能在去的路上）, have been in 表示去了并且到现在为止还在那儿。
例如：1）--Where is mum?
----She has gone to the market.(在路上或已在超市)
2）My father has been to Shanghai. He often says something about it.
3）I have been in Guangzhou for one year.(现在依然在广州)
注意：have been to与have gone to 都表示瞬间动作，不与for, since引导的时间状语连用，而have been in 与表示时间段的词连用。
