Nick and his father are travelling on a train. Nick likes to stand and puts his head out of the window. It's dangerous. So his father says, "Sit down! Don't put your head out of the window!" But Nick doesn't listen to his father. He still puts his head out of the window.
His father has an idea. He takes Nick's cap quietly and says, "You see, your cap flew away. Sit down! Perhaps (或许), your cap will come back." Nick is afraid and he sits on the chair quietly. Nick's father puts the capon Nick's head.
Oh! It is wonderful! Nick is happy. He takes his father's cap quickly and throws(扔) it out of the window. "Now it's your turn, Dad!" Nick says happily.
