Billy lived on a quiet street in a big city. His mother sometimes took him to the park, but when she was busy, he played in the street alone.

    One evening, Billy's father gave him a beautiful new ball, and the next morning Billy went out into the street to play the ball.

    He playedby himself for a few minutes, and then a big dog came along. The dog wanted to play the ball, too.

    Billy picked the ball up and held it above his head. He did not want the big dog to take it and ran away, but the dog jumped up and knocked him over.

    Billy's mother came out of the house and ran to him at once, “Did he bite (咬）you?” she asked.

    “No, he didn't bite me,” Billy answered, “but he tasted me.”
