Dear Wang Qiang,

I’m glad to hear from you. I’m very sorry that you have some trouble with

your English. Now let me give you some advice on how to learn English.

First, you should memorize more words and expressions so that you can enrich your vocabulary, which is very important in English learning.

Second, you’d better listen more to some English tapes or CDs and try to follow the correct pronunciation and intonation. In this way you can improve your listening so that you can understand your teacher better in class.

Third, you can do more reading out of school in order to improve your reading skills.

I hope that my advice can help you. I also hope that you will make progress in English and catch up with your classmates soon.

Best wishes for you!

Yours,

Li Ming
