Dear friend,
If you want to learn English well ,I can give you some advice.
First,you should spend a lot of time to practise your English. Such as listening English songs on the radio,speaking English to your classmate,reading English newspaper and writing English positions.
Then you should try to listen carefully in your English lessons.You should be brave to talk with the foreigners.You should read a lot and practise your writing skills.
I hope that all I say can help you.
Best Wishes!
Yours,
LiLei
