 Dear Sandy,

     How are you? It's Saturday today and I have some time to write to you. We're busy from Monday to

 Friday. We have to get up at six thirty in the morning. After some exercise we have breakfast. We have

 five classes a day and the first class begins at eight. Our teachers are strict and we can't be late for school.

  They often ask us a lot of questions and some of them are difficult.

     We do sports at five in the afternoon. We play basketball, soccer, volleyball, tennis or ping-pong.

 Some of my classmates like Art. They can sing or dance or draw. Sometimes Miss White, our Biology

 teacher, takes us to the zoo and we visit the animals there. At six we can leave our school.

     After supper we can watch TV. But we have to finish our homework first. I like Math and often do

 some difficult exercises. So I go to bed at ten thirty. I'm often tired but I like it.

     Please write to me and tell me about yourself.

                                                                                                                                    Yours,
