Dear Wang Jun,

     Thank you very much for your letter and the photos of Beijing. Beijing looks very beautiful! I'm fine. I have a good

time. And I'm very busy with my lessons. I have six classes every day, four in the morning and two in the afternoon. I

like English very much. I'm learning Chinese. Chinese is very difficult. I do my best to learn it, but I'm not very good. I

like P.E. best because it's very interesting. I can play football and basketball. By the way, do you like English? Can you

speak English well? What do you think of America? Welcome to New York(纽约). I hope you can come to New York

one day.

                                                                                                                                                                Love,

                                                                                                                                                                Frank
