I think, nowadays it's important to know English. Because English is the one of the international languages. And if you know English you'll have more chances to become a professional at your area.
Everybody knows that the best education you can get is only in the USA or in the UK. So if want to have the best education you have to know English.
By the way, for me, English is a beauty. When I read books, watch English films or serials, I really enjoy how it sounds.
Can I ask you? Can you give me a reason why anybody shouldn't learn this beautifull language? I guees, in the all world haven't a reason, why nobody should know English.
To conclude, I want to say that I love English. And I promise, that I'll improve it more. Because, how I said before(and gave reasons), English is important.
