Professor Tony's English Classroom

This site is really interesting. Honestly it looks like there is a ton of stuff here and this could be a really, really interesting site for research on English writing in China. Professor Tony's English Classroom is a site for Chinese students of English writing, and

"its purpose is to provide the best possible help to any and all people here in China that want to improve their English. And the best part of it all is that everything is FREE OF CHARGE!"
