People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.

     But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.

     Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.

     Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    Jim, with his father, goes to see his grandfather. In the train Jim often puts his head out of the window. His father says, “Jim! Don't put your head out of the window!” But Jim goes on putting his head out of the window.

    His father says, “Well, whistle (吹口哨) once. Maybe your cap will come back.” Jim whistles. His father puts quickly the cap on Jim's head.

    Oh! It is wonderful. Jim laughs. He quickly takes his father's cap and throws (扔) it out of the window. “Now it is your turn to whistle, Dad!” He says happily.

    Cody and his sister April decide to buy a dog. They go to the local pet store and have a look around. It is a very small pet store that doesn't have many animals.

    The owner of the store is a nice old man-Mr. Smith. He walks over and greets Cody and April.

    "How can I help you?" he asks.

    "We would like to buy a dog," April responds(回答).

    "Ah, well, our shop is not a big pet shop," Mr. Smith tells her. "So we only have two dogs to choose from."

    They ask Mr. Smith to show them the dogs.

    Mr. Smith leads them to the back of the store where the two dogs are. One of them is a very big bulldog(斗牛犬) named Buster. The other is a very tiny chihuahua(吉娃娃) named Teacup.

    April wants Teacup. Cody wants Buster. They walk outside to discuss.

    They can't agree on a dog. April suggests they race home for it. The winner of the race chooses the dog.

    Cody runs as hard as he can. He really wants that bulldog. He looks back. April is so far behind, and he can't even see her.

    Cody finally gets home. He is tired but he is happy. He knows he is the winner.

    April arrives a few minutes after Cody. She congratulates him. They return to the pet store to purchase Buster, the bulldog.

    However, when they arrive they only see Teacup.

    They ask Mr. Smith where Buster is.

    Mr. Smith gives the details. He explains that a few minutes after April and Cody leave, two boys walk in and buy the bulldog.

    Cody looks at April, and she holds back a smile. He turns back to Mr. Smith.

    "Sometimes you win the race, but not the prize!" Cody looks sad. "We'll take the chihuahua, please."
