An officer（军官）is at a bus stop. He wants to see his girlfriend by bus. He wants to tell his girlfriend the time of his bus, and then she can meet him at the stop in her car. He wants to call his girlfriend on a pay phone（付费电话）,but he doesn't have a coin（硬币）for the phone. He wants someone to help him.

    A soldier（士兵）is near the stop. The officer walks to the soldier and asks,“Do you have any coins for the phone?”

    “Let me have a look,” says the soldier. “I'll see if I can help you.”

    “Don't you know how to speak to an officer?” says the officer. “Now let's say it. Do you have any coins for the phone?”

    “No, sir,” says the soldier.

    Bill is a smart boy. He can do all the math problems(问题) in his math book.

    One day, on his way to school, he sees a sign of a fruit store. It says: "Apples: Six for five  cents(美分)". Bill knows what to do, so he goes into the store.

    "How much are the apples？" Bill asks the man.

    "Six for five cents."

    "But I don't want six apples."

    "How many apples do you want？"

    "Well, it's not a question of how many apples I want. It's a math problem. If six apples are worth(值) five cents, then five apples are worth four cents, four apples are worth three cents, three apples are worth two cents, two apples are worth one cent and then one apple is worth ZERO! I only want one apple."

    Bill chooses(选择) a good apple and starts to eat it. The man is so surprised(惊讶的) that he can't say a word!
