All the English I know I have learned by exposure. My comprehension skills are good enough to participate in a language exchange program, but, outside of comprehension, all my other skills are pretty  poor. I need to learn English because I like it and because I have counsins in the USA. My mother also has childhood friends living outside of our country(They usually come to Brazil every year).

   I  need to improve all my other skills. And I would apreciate any advice. My biggest challange is pronunciation.
