Is there anybody who can help me improve my English graduate paper? I think what I have written is not so good, and I want a native speaker to help me do some modification. If you can help me, just send a mail to [email protected], then I will give you my paper. Because it is a big one, you know. To pay back, I would like to teach you Chinese for free, Pinyin or something else. I have Skype. Thank you.
