      This story is about a young man. He worked very hard at his lessons. He was too busy to have

a rest. At last, he became ill, so he couldn't go to sleep. Every night, when he went to bed, he closed

his eyes and tried to sleep. But the more he tried, the more he stayed awake.

     After a while he decided to visit the doctor. " I just can't go to sleep at night. What should I do?"
