【答案】Dear Michael,
I'm happy to tell you how Chinese students keep healthy. And I would like to take myself as an example.
First of all, a healthy diet is very important, so I eat food like rice, eggs, fish and vegetables every day. I also eat more fruit and drink enough water. Snacks and fast food are bad for our health. I seldom eat them.
Also, I take enough exercise every week. It keeps me away from getting sick easily and helps me study well. I do morning exercises every day. And I usually walk, run, jump or play football after school. Doing sport makes me relaxed.
That's all I do for a healthy body. How about you?
Please write to me soon.
Yours,
Li Hua
