被动语态的结构?have/has been 和 have/has gong 的用法和区别?

1.have与has只是人称和数的变化,如第一人称I、We与第三人称单数he/she.
2.been和gone这里不是被动语态.
但been 可以参与构成被动语态,例如
I really don't know why he has been beaten so hard.（我真不知道他为何被揍得那么厉害）
3.动词go的一个用法表示visit参观时现在完成时可以用been或gone但表达的意思不同.
She has been to Paris.(=She visited Paris some time ago)
She has gone to Paris.(=She is now in Paris or on the way there现在巴黎或在去的路上)

has been 是曾经去过，已经回来了
has gone 去。。。，没回来
如
He has been to Beijing. 他去过北京。
He has gone to Beijing. 他去北京了。
