I need a way to practice speaking and writing in English.

My main problem is that sometimes I feel that I'm translating english in my own language ,so it sounds unnatural to a fellow english speaker.

The other way that I've is to speak but is really hard to find someone to train with you frequently because there are millions of brazilians wanting to speak english and not so many on the opposite,and there is the Aggravating factor that a lot of us are on a low level or have poor education,mainly the guys trying to pick up foreign girls with shit english...
