Liu Kai is my classmate. He is a good student and always ready to help others.
One day on his way to school,he saw a little girl crossing the road. A car was coming towards her quickly and the girl was too frightened to move. The car nearly hit her. Just then LiuKai rushed up to her and caught her by the arm. The little girl was saved. She told him where she lived, and he took her home. When LiuKai hurried into the classroom, the teacher had already begun his lesson. He told the teacher why he was late. He was then praised for what he had done.
刘凯是我的同班同学。他是个好学生，总是乐于帮助别人。
有一天，刘凯在去学校的路上，他看见一个小女孩过马路。汽车迅速地冲向她，这把女孩吓的走不动了。那辆车差点撞到她。这时刘凯冲到她面前，抓住了她的胳膊。小女孩得救了。她告诉他住的地方，他带她回家。当刘凯急匆匆地赶到教室时，老师已经开始上课了。他告诉老师他迟到的原因。然后他被表扬了。
