How to improve your language skills

Hi everyone, I read some Chinese articles written by foreigners tonight, which encouraged me to write an English article. Maybe it's a good way to improve one's language skills.

Of course, language environment is also very important, but most of us do not have this available to us. Therefore, using a website is really helpful, as is ITALKI. 

I would really appreciate the English native speakers correcting this article for me.

Thanks a lot!
