XX 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 XX 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 XX 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.
