    It was Sunday yesterday. We had a picnic in the park. We went there by car. There were so many people in the park. I saw some birds in the tree. They sang beautifully. Some old men did taijiquan under the tree. I played football with my friends. Then I was thirsty（口渴的）, so I drank some water. The girls played games. We were very happy.
