Dear xiao ming,
I'm glad to tell you how to learn English well.At first,you should listen carefully in the class,and speak much in your daily life.Second,you're supports to read widely to open up your eyes.Next,you will improve your English if you learn it by heart.Finally,you also should practice writing as often.
I think listening the English music or watching English movies can also help your English.
Yours,
