Hi, I'm Judy. I'm a middle school student . In my class, there are thirty-eight students. How do they go to school every day? Seventeen of them take buses because they live far from the school. Six students walk. They think walking is good exercise. Fifteen students ride their bikes to school because they like riding bikes very much and their homes are not far from the school. No one goes to school by car. How do I go to school? Ha, I'm one of the fifteen. Six students think  _  is good exercise.
