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 when a car nearly hit her. Just then Liu Kai 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 Liu Kai hurried into the classroom, the teacher had already begun lesson. He told the teacher why he was late. He was then praised for what he had done.
