Here are some suggestions for Li Bing.
First,I think listening to some tapes or English songs is the best way to improve her listening skills. Second,watching English language movies isn't a bad way. She can watch the actors say the words and read after them. Third,join an English language club. She can find a partner to practice English with. By this way,she can practice both his listening skills and his speaking skills.
