Barry Parker was a very successful businessman. He lived in a large house and drove a car. He wore expensive clothes and ate his meals in famous restaurants. His name was often in the newspaper. One day a newspaper reporter asked him, “What is the secret of your success(成功)?”
    Barry thought for a few moments and said, “I eat a special kind of fish.” “You eat a special kind of fish! What does that do?” “It makes my brain work better.” Barry said. “What kind of fish is it?” the reporter asked. “Give me fifty dollars and come back tomorrow. I'll have some for you.”
    The reporter gave Barry fifty dollars and returned the next day. “Have you got any special fish?” “Yes. Come into the house. It's in the refrigerator.”
    Barry took the reporter into his kitchen. He opened the refrigerator and took out a very small fish. “Here you are. Have this for dinner.”
The next day the reporter called on Barry again. “Did you eat the fish?” Barry asked her. “Yes, I fried it.” “Good, do you feel different today?” “No, I don't. And I think that fifty dollars was a lot to pay for such a small fish.” “Well done !” Barry said. “You see, the fish is working. You're using your brain now.”
