Составить рассказ по английски "содержимое портфеля"

I've got a good school bag. It's big and cosy. I can put a lot of things there. There are textbooks, copy-books and pencil-case in it. There are pens, pencils and other necessary things in my case. I always use them during the lessons. If I have no many lessons, I can put my sport uniform in my bag, in order to put it on at the PE lesson. I think, my school bag is nice and useful. I like it very much.
