　　Sunday, April 9th

　　The weather was fine. All my classmates went to the park.

　　We climbed the hills, boated on the lake, and flew kites all morning.

　　At noon, we had a picnic near a big tree. In the afternoon, some girls

　　sang and danced, some boys talked in English, and some students

　　played games there. When we went home, it was late. I was tired, but

　　I was really happy.
