There are some ways to improve your English. Here's some advice for you.
Listen to the radio in English. If there are no English radio stations where you live, listen to one on the Internet.
Watch TV and movies in English. If you have English channels(频道) on your TV, watch them. If there are no English channels, you can buy some DVDs of English movies.
Speak English to your friends. You can find a friend who is good at English and speak English with him or her. You'd better find friends whose native language is English.
Study or travel to an English-speaking country. Of course the best way to improve your English is to live in the English environment(环境). It may be a more difficult and expensive choice, but you can find that it is a very valuable and helpful experience.
