I want to learn English.

I am a college student now.I am from China.I learn English in college.But my English is not very good,so I want to find a partner to improve my English.I have msn, skype and line.I want to communicate with others on msn or skype,because it is easy.
I like running.I think running can make me strong. And what's more, I like playing on the computer.( The idea you maybe wanted to say is "I like even more playing on the computer" is that correct?) I think the net world is wonderful. We can learn (the word knowledge is not absolutely necessary) new different things and make friends from all over the world on the internet.
I hope I can find a good friend by italki. And it will be better if that friend is good at English.

Hello! your grammar is excellent! Is good that you want to practice outloud, that will help you to espeak more naturally. It can be challenging to adapt your mind to the way English communicates the ideas, but you are doing it very good so far. Greetings!
