When I came to study at Xin’an Middle School one year ago, I was very lucky that the class commissary in charge of sport became my deskmate. His name was Cai Du. In my heart of hearts, I think he is excellent at his job. I like him very much.

    He is a bright and optimistic person, with a gentle and amiable character. He is always kind to others. When I play tricks on him, he takes them good-naturedly. When I fail exams, he does not pick on me.

    I am a little overweight, so he often runs with me after school to help me lose weight. He leads the class during morning exercise, which is held in the playground every day except on rainy days. He is lively, smart and strong. We all like him very much.

    In my opinion, he is not just a class commissary in charge of sport but he goes beyond these duties. When classmates are in trouble he is always there to help them. One day for example, we were having a science class, a classmate suddenly felt sick and vomited on the floor. The vomit was terrible and smelled bad. We needed to clean it up immediately but nobody wanted to do it. It was Cai who stood up and cleaned the floor. He was so considerate! We all looked at him quietly and thanked him from the bottom of our hearts.
