Possible version:
I like collecting all kinds of books. I’ve collected about five hundred of them so far.
Most of them are bought from bookstores. I keep them on my bookshelf in order.
I like to collect books because I not only take good care of them but also enjoy reading them. I always regard the books as my close friends. I think books have brought me a lot of pleasure and made my life colorful.
In the future, I’ll have a larger collection of books. So I am going to offer most of them to the children who live in the poor areas. I believe they will learn a lot from the books I give them.
