Dear Tom,

     I'm glad to receive your letter ask for my advice on how to learn Chinese well Here is a few suggestions.

     First, it was important to take a Chinese course, as you'll be able to study from the teachers and practise

with your fellow students. Then, you'd better watch the TV and read books, newspaper and magazines in

Chinese.

     Besides, it is a good idea to listen Chinese songs, because by doing so you'll learn and remember Chinese

words more easy. You can make much Chinese friends. They will tell you a lot about China and help you learn

Chinese.

     Try and write to me with Chinese next time.

                                                                                                                                                Yours,

                                                                                                                                                Liu Wei
