I'm Tom. I'm a healthy boy. I play sports every day when I come back from school. My habits(习惯) are very good. I try to eat a lot of vegetables. I eat fruits and drink milk every day. I never drink coffee. Of course, I like junk food. But I seldom(很少) eat it. Oh, I sleep nine hours every night. So I do well in my study. Good food and exercise help me study well.
