Unit 1 Keeping Healthy Lesson 3 A

原文：

Dear Linda, I always feel tired and sleepy.
I sometimes sleep in class.
I like my teachers and I like all my subjects.
but I don't get good marks.
At night I can't sleep,so I go on the computer or watch TV.
It's not good.
What should I do?
Worried.

Dear Worried,
Many students have this problem.
You are going to be OK.
I have some advice for you.
First,you should exercise every day.
Play football or basketball with your classmates or do morning exercises.
Next,you shouldn't play too much on the computer or watch too much TV.
So turn off the TV and computer at 9 pm.
Try to walk more and help your mum do some housework.
Finally,you should go to bed before 9:30.Try these things.
I think you'll soon feel better.
Linda.
