dear xiao ming
l’m glad to tell you how to improve your English. At first, you should listen to your teacher carefully, and speak English as much as possiple. When you read English, please read it widely, because it will help you to learn it better. It is very important to learn it by heart, too. You can also improve your English by practicing writing in English. I think listenning to English songs is also a good way to learn more English, you can have a try.
yours,
xiao hua
