Hi, My name is Derek. I'm from San Jose, California, in the United States. I've been teaching English in China since February 2008. I teach in a famous English education group in Jiangsu Province. I teach oral English, business English (BEC), IELTS and TOEFL. I've listed 37 of the common mistakes made by Chinese speakers, and I've gained a lot of experience in teaching students how to identify these mistakes and avoid them. Hope I can help you to improve your English!
