Dear Jack,

How are you? I have been in the USA for six months. I like the life here. I have a few friends. I don’t have much homework. There are a lot of sports at my school, but I don’t like sports at all. I like the food very much. I eat a lot of different kinds of food every day. I like coke（可乐）very much. I don’t drink water. I drink coke instead（代替）. I’m enjoying my life here. The sad thing is that sometimes I get ill. I don’t know why. My parents say I must go on a diet and do more sports. Must I?

Yours,

David
