Which Website Do You Like Best?

I come from China.
I'm interested in American culture,
so I want to get more things through the Internet.

Please tell me some websites that you are most interested in,
then give me some advice on learning more things about the USA.

I haven't been to the USA before, but maybe years later, after my graduation from my high school, I can get a chance to visit that Great country.

Thank you for your answers, SINCERELY!

If there is anything that I can help you, especially problems about China, do tell me and I'll help you sincerely as well!
Good Luck!
