Jim, with his father, went to see his grandfather. In the train, Jim often put his head out of the window. His father said, “Jim! Don’t put your head out of the window!” But Jim went on putting his head out of the window. Then his father took Jim’s cap quietly, hid (藏) it behind his back and said, “You see your cap is gone (不见了).” Jim was afraid. His father said, “Well, whistle (吹口哨) once. Perhaps your cap will come back.” Jim whistled. His father quickly put the cap on Jim’s head. “Oh! It is wonderful!” Jim laughed. He quickly took his father’s cap and threw it out of the window. “Now it is your turn to whistle, Dad!” he said happily.
