Why I need to learn english. I work in the academic world, specially in topics related to the electrical engineering. In this field the language that is used principally is the English. The best information that can be find is in this language well as conferences, symposia, and anything related to this area. I need to learn principally because I'm meddled in this world but besides because is a language that people use in a lot of countries in the world where principal language isn't the English, so if I have the chance of travel I think that learning english I will can to have an opportunity to communicate me easily.
