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，总是乐于助人。
一天在上学的路上，他看见一个小女孩正在过马路。一辆汽车迅速向她驶来，女孩吓得动弹不得。汽车差点撞到她。就在这时，刘凯冲向她，抓住了她的胳膊。小女孩得救了。女孩告诉刘凯她住在哪里，刘凯带她回家。当刘凯匆忙走进教室时，老师已经开始上课了。他告诉老师他迟到的原因。然后，他因所做的事而受到表扬。
