Learning english at university is pretty much different that learning it in high school. Back then we only had to be able to participate in the class and to talk the language from a very general perspective. I mean we only had to talk about ourself and our experiences. But in University the thing got pretty more difficult.
Every language is a tool to build a world, to understand your reality with other glasses on. That what I learn to do in University, throughout the knowledge of the skills that would help me out to express myself in the correct way, I understood that the english was a very different way to see our world and our quotidian life. I wasn't only about learning to translate some sentences and some words to make us see more comfortable with the language, but it was a new way to think our reality.
Writing this blog gave me the skills to make an opinion out of any subject. Every week we had to write about something different and that was a very crazy way to learn the language because we had to look into our head the right words for every situation.
Anyway, I think that I need to learn a more formal english. What I'm trying to say is that I use to watch a lot of series and movies, all of them from the United States, except for two or three, and gave me a very informal perspective of the english.
