This forum does not work like that. We try to help people with specific problems - we are not here to replace grammar books.
Also, please remember what I told you in another thread:
Please mark out the words you are asking about in some way:
I have to know how to use a 'has been' and 'had been.
I have to know how to use a "has been" and "had been".
I have to know how to use a has been and had been
It's also normal to make a request rather than simply state your need:
I have to know how to use 'has been' and 'had been'. Can you help, please?
In future, give an indication in the title of what your question is about. Has/have been/should be? would have told us far more than grammar - many of the questions submitted here are about points of grammar.
