The Opened Door

Why do (without the "do" it's more of a statement than a question) I think that it is necessary to learn a language like English if I live in a country where we just speak Spanish? I could want to travel to meet new people, but it that (want used previously is future tense whereas it is more present tense so you were switching tenses)  is not the main reason.

The knowledge is more diffused in English than in Spanish and is technically more precise. We are studyng studying engineering and I would like to learn complex things that where they were researched, they were universally diffused in English.

For some countries, like mine, the English is like a an (can't have two vowels next to each other for different words like a opened. Vowels: a,e,i,o,u sometimes y) opened door. I think that in the future, that door could be the Chinese and Indian language. We will look at how both countries will grow in the future.

EDITORS NOTE: I think you did a really good job. The mistakes were very small overall. The last two sentences however I don't feel they really articulate what you're trying to say. I think you are trying to say the English language opens a lot of doors for you and that door could eventually be Chinese (proper Mandarin/Cantonese) and/or an Indian (<--notice "an I") language. Overall great job and keep up the good work :)
