Read literature in English, watch film and listen to music, talk in English.

You should have born native English speaker to know language as deep as they do. Or live in the English spoken country about 10 years. It's an ultimate way too. :) And one more - practice makes perfect.

Here is a friendly italki teacher who is a native English speaker for you http://www.italki.com/T008169345.htm Here are the Italki English/ Chinese speakers. Email some of them and invite them to be your friend or language partner. Then set up a time to chat on msn or skype. Remember the time differences between countries, If there is a green light next to a person's name, it means that they are on line. http://www.italki.com/partners/1-Chinese-English200-0--0-0.htm

Lots of practice, but don't be discouraged. Just search out good examples, imitate them, and enjoy the journey.
