I am Danny. There are four people in my family. My father, my mother, my sister and me. Last Sunday was a fine day. My family went to the Zhongshan Park by subway. We went hiking in the park. At first, all of four were happy and excited. Father is stronger than all of us, so he took many things in his bag. We played games, sang songs and danced in the park. But suddenly, my sister fell down. Her leg hurt. At last, she had to go to see the doctor. We were sad in the end.
