Learning Other Languages

To learn a new language is not so easy, but it is not impossible. In my view, languages are divided into two parts: grammar and conversation. When we study grammar, we improve our reading and writing skills. On the other hand, when we study conversation, we improve our speaking and listening skills.

(The next paragraph is missing something. I could modify, but that would not help you because it may not be what you meant.) 
I was listening from a english teacher that more than we practice and try to memorize the grammar rules, it´s better to study the culture, and the pronunciation of the language, practicing with native speaker, because, unfortunately in Brazil, there are a lot of students that finish the english courses, and they know all about grammar but don´t understand nothing of listening and speaking.

These are my thoughts. If there are something wrong, don´t hesitate to correct me please. Thank you.
