Undecided questions
why english language is very important???

This depends on what one person wants to do in their future. English is considered the international language. Probably declared by America..... >.>... But there are more people in the world that speaks Chinese (Mandarin). I guess Chinese is too hard for some people.

I have another good answer, English is important otherwise I wouldn't be able to communicate with you =P

English is the language of computer programs [ yes ,you are right Niney chan!] and of International Business.

La langue Anglaise est parlée par un grand nombre de pays. Elle la 4ème langue au monde. Elle est importante parce qu'elle est la langue principale des échanges commerciaux et technologiques.

Mais au niveau culturel, la langue de Molière est de loin la meilleure.

because is the best way to learn any other language. I like my native language ( spanish ) better ( it's somehow more lyrical ) but english is cooler!

Actually, I'm pretty sure more people speak Spanish than English as well as Mandarin; right?

Yes why..... I doubt there is a person who can make a good logical argument for this question. English is no better or worse than any other language, it is just because of the course of history that English is the international language of choice.
