how related reading and writing are

I really love reading. When I was a university student, I read a lot of books. Most of  books I read was about non-fiction, sciense, and history.  When I read books which are little bit difficult to understand, I always take a note in order to make it clearer.  If I do that, I can remember some unfamiliar words without hard work.  In particular, when I meat new notions that authors freaquently use, I have to completely figure out  the meanig of that. Otherwise I can't really understand what authors wanted to say.When I call reading "imput", writing is "output". Absolutely both are necessary for language.

I have read and written a lot of things in English since I came here.  Basically vocabulary I used in my writing is easier than one I learn from reading.  But I always try to use new words I learned in reading class.  In most cases, teachers modify my usage of the words. That's why I try.  I hope I'm gradually improving my vocabulary with repeating reading and writing.
