Think in English, talk in

English, read English, write in English, memorize some good English paper, phrases and words and sing in English. Do everything in English Don't be afraid you may lose your Chinese, you will not, at least not that much. Don't be afraid that people will laugh at you. That's their fault not yours if they do. Remember you learn English for nobody but for yourself. People will admire you rahter than laugh at you once your English is excellent.
