Dear Li Peng,
How are you going? I'm sorry to hear that you are not good at English,I'd like to offer you some advice.
First of all, you should recite the words as more as possible and read the articles regularly.The next , it's a good way for you to speak English with your friends as more as you can, then youwill meet problem possiblely ,you can ask the question to your teacher to improve your English. The last but the improtant is answer your English teacher's question in the class.
I hope my advice is good for you and you can make a great progress.
Best wishes !
Yours,
