I have already read them and I am searching for something in a passage format, something that is going to improve READING by which one can also improve vocabulary.
I'm sorry, but your thinking is totally backwards. You should start reading random texts (articles,short stories and novels) written in ordinary language as soon as possible, so that you get acquainted with actually used vocabulary and phrases.
There's some great computer software to review your previously studied material, Supermemo is pretty nice.
