阅读下列短文，根据短文中的信息完成文后表格。（每空一词） Dear Nancy, I am happy to tell you my school and my life. Every day my father drives me to school. My school is very big and beautiful. I like my school very much. The desks and chairs are new. There are lots of pictures on the walls. You can also see some flowers on the teachers’ desk. We clean the classroom every day. I don’t go to school on Saturday and Sunday. I get up at six on Saturday. I play basketball with my father in the park near my home for half an hour. Then I eat my breakfast. I help my mother water the trees and flowers in the garden. At eight I begin to do my homework. My parents and I have lunch in the KFC. In the afternoon, I have Art lessons. Sometimes I play computer games or chat with my friends on the Internet in the evening. I like my weekend very much. Yours Li Hua
