I can help you to improve your English, and you help me with my Mandarin, what do you think? I've taught English for more than six years for Portuguese speakers, I've been living in US for five years, and I'm studying linguistics. So, I have a little experience :)

Maybe buy an English dictionary :) it helps.^^

1. Find Language Partners - Click on 'Language Partners' to find a native speaker to practice oral communication or just to learn about other cultures. 找语言伙伴 - 到语言伙伴中去寻找，要主动一点。可以从简单的对话开始交流。 2. Find a Language Teacher - You can find a professional teacher when you click on 'Language Teachers' to formally instruct you. Or you can hire a tutor to help you with your homework or materials. 如果你的经济上允许，你也可以找一名专业的教师来帮助你。italki上有不少的英语教师资质都是不错的。并且价格也相对一些培训机构的便宜很多。 Good luck!!! 祝你好运！！！
