studying

I love reading. It's my passion, my pleasure.
However, I prefer reading magazines and newspapers instead of books because I almost don't barely have time to watch the news on tv, and I like to be updated.
I also have been reading a lot in English. I work in front of a computer and enjoy to studying English in on good sites like Italki all day long.
Also, there are good Portuguese sites that teach free English by on the internet.
This These sites are very important for an English student, because when we study, we have lots of doubts, especially about grammar, that others people also can may have and they help us a lot.

"Instead" is used when both the sources have the same informations, but here in your case you are talking about the magazines and the books, that may have differnt informations, so the word "rather than" is more suitable than the the word 'instead".

your english grammer is good, keep it up, best of luck.
