     One afternoon little David was playing with his friends in the street when he was hit by a motorcycle.

He fell and broke his arm. And he was immediately taken to a hospital. There a doctor operated on his arm

and put it in a cast (石膏)-David couldn't move it at all.

     "You must keep your arm in the cast for a month," the doctor said. "That will give your arm a chance

to become healthy again."

     At the end of a month David went back to the hospital. The doctor cut the cast and took David's arm

out of the cast.

     "Can you move your arm, David?" he asked.

     David tried to move his arm. At first it was difficult, but soon he could move it easily.

     "Yes, it's fine," he said. "Thank you very much."

     "In a few days it will be as good as new," the doctor said. "Just exercise it a little."

     "Will I be able to play the violin?" David asked.

     The doctor smiled. "Of course you will," he said. "You'll have no problems."

     "That is good news," David said happily. "Because I couldn't play it at all before."
