思路点拨
　　写记叙文要按照事物发展的客观规律叙述,所叙述的内容要交代清楚,条理清晰,重点突出,主次分明,详略得当。

　　这篇文章也是记叙文,主人公应该用第三人称,时态以一般过去时为主。本文以主人公为中心线索,以一、两件事件为重点内容去组织材料,反映主人公的形象特征。整个内容情节要合情合理,有真实感,叙述时可按事情发展的顺序进行,同时加以点评。

　　My Classmate
　　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.
