A doctor is talking about how to keep healthy with Victor.

Doctor: I heard that you learn with computer.

Victor: Yes, we each have a computer. We learn Chinese and English in the network-based classroom.

Doctor: In that case, you should take care of yourself. You shouldn't sit for too long at the computer.

Victor: Our teacher always asks us to have a break after each class.

Doctor: Yes. You still need do more exercises. It is good for your neck.

Victor: We usually do our NECK EXERCISE. We all like it.

Doctor: Great! Besides, you need to make sure that the height your desk and chair is correct.

Victor: We have changed a set of new desk this year. We are taller.

Doctor: Oh, you are big guy now. Ha, Ha…

Victor: Of course.

Doctor: You should eat plenty of vegetables and drink more milk. You will grow much taller than now.

Victor: Really.

Doctor: I am sure. Doing more sports is also very important. Which sports do you like best?

Victor: l love playing football.

Doctor: That is good for young man. And when you use the computer, you'd better drink plenty of water.
