It is nine thirty in the morning. Mr Green and his students are going out on a picnic（野炊）. They’re now in the park. The children are having a good time at the moment. Look, the girls in the beautiful dresses are Su Hai and Su Yang. They’re singing and dancing. Who’s the girl under the big tree? She is Nancy. She is reading a storybook carefully. Where is Mr Green? He is playing games with Helen and other students. But Liu Tao and David are fishing near the river. Then a park keeper comes up to them. He points to a sign near the river. He says to the boys, “Can’t you see the sign over there? It’s says ’No fishing, please’.” Liu Tao and David say sorry and leave（离开）there quickly.
