Although it may be difficult in the beginning, you need to force yourself to speak English. Don't worry if you are nervous or make mistakes. This is part of learning. If people don't understand you at first, don't give up and keep trying. My advice is: make friends with a lot of native English speakers, and talk to them a lot. Don't surround yourself with only Chinese-speaking friends. I see a lot of Chinese students in my university do this, and they wonder why they don't have strong English speaking skills. The best situation would be to study abroad in a place where people speak English, such as USA, Australia or UK. If you can't do that right now, find some native English speakers to chat with on Skype. Good luck. :)
