An Accident
参考范文：
One day, Mr. Li was reading a book in his office after school when a ball broke the window and flew in. Mr. Li was greatly shocked when the ball hit him on the head. He took the ball and came downstairs to see who threw the ball. He met a little boy at the doorway and the boy said it was he who had thrown it. The boy said sorry to Mr. Li and Mr. Li praised the boy for his honesty. Mr. Li told the boy to be more careful next time. The boy thanked him for his kindness and said goodbye to him, running away with the ball.
