Dear Anna,

     Thanks for your letter. I'm glad you like your school. I go to school from Monday to Friday. We have

five classes in the morning and two in the afternoon. And we have many subiects to learn: Chinese, math,

English, P.E., science, biology (生物), music, history and so on (等等). We also have many things to do

after class. On Monday and Wednesday afternoon we play sports after class, and on Thursday some have

a dancing class. I like music, history and English. But my favourite is music. 

     On Saturdays and Sundays I don't go to school. Usually I go to the park and have a good time with my

father and mother there. 

                                                                                                                                              Love,

                                                                                                                                              Lin Fang
