OK, to talk about English language is very difficult because I'm not very good for it. 
I believe that English is an hegemonic language and for this we need to learn it. But, I think, it's OK, everyone talk English, then it maybe can help me to communicated in particular times, however, exist other languages in the world, equally important than English. 
In science, English is the most common language, then other knowledge that is'n in English are not taken into consideration.  
Respect this subject, I think that the teaching methodologies are very bad, because they aren't near to my studies area. 
Learn English when somebody has 20 years old is difficult. The subject English would be teach in the first years of school, when we have 5 o 6 years old. Then, learn English in the university many times can be stressful because we have other subjects more important maybe, we see it this manner.
About the blog, I can say that is very funny for me, write is the only thing easy for me in English. Then, I like writing about things that I want, and other topics. 
Well, I need to improve reading, I know that I can say English (because I can write), but I feel very nervous then I do it wrong. And also, I can't listening, every time I can't understand about what they are speaking.
I think to improve this practice some topics and what can I say about this, like free time, university, food, family, etc. And practice and practice jaja. :( 
I use English for to reed some text or papers that I have to reed for some subjects, but I never do this, I prefer reed some abstract that other colleague do it. And I use English when I watch tv show? maybe? jajaja I don't know.
Ok Teacher. See you! bay
