I have been selling
I have been trying
I have ever been
I too have been
I have been to.
I have been
I have been in.
I have been there,have been 是have been in还是have been to的缩写?
i have always been there i have never been there
I HAVE NEVER BEEN,能否说I never have been
I have been so serious I have been so serious
I-have-been-at-home
I have always been you
I have been loving you
I have been a person .
I have never been away!
I have been wet through
because i have been died.
