I have to say that Chinese are really smart, or at least Chinese students are really quick at learning English writing.
A week ago, I started to edit a manuscript written by a beginner. Half way through, I could not take it any more. Why? I was doing less than English editing, because of various "small errors" here and there, involving spacing, punctuation, etc.
So, I sent the manuscript back, with instructions for revision. I also wrote a few Blog on how to fix these problems. (See my Blog in the past few days on English writing.)
Today, the revised manuscript came back. I was a bit nervous, because I was not sure how much improved it would be. To my surprise, it was so much better!
I am so pleased with this graduate student that I suggest that he give a seminar to his fellow students on English writing.
