When people find something valuable and return it to its owner，they are often given a reward．This is because the person not only found what was lost but also spent time finding its owner or taking it to the police station．

    There was once a young boy who found a woman's purse in a shopping center．Inside the purse there was some money and the woman's driving license．Her name and address were printed on the license，so the boy knew where she lived．That evening he went to her house and knocked on her door．When she opened it，he said，“I found your purse，''and handed it to her．

    “Thank you very much，”she said．She opened her purse and took out all the money．She wanted to give the boy a small reward，but there were only bills of$20 in the purse and she thought that$20 was too much to give the boy．“I'm sorry，”she said. “but I don't have any small change to give you．”

    The boy said，“That's all right，”and he went away．

    A few days later he found another woman's purse．It also had her driving license in it，so he knew where she lived．He went to her house and said．“l found your purse ,”and handed it to her．

    “Thank you very much，"she said．  She opened her purse and took out all her money．

    “That‘s strange，”she said．“Before I lost my purse l had a $100 bill and a $20 bill in it．Now I have a $100 bill ,a $10 bill and two $5 bills．''

    “Yes，"the boy said，and smiled．

    Once upon a time, the colors in the world started to argue. All thought they were the most important and useful.

    Green said, "I'm the symbol of life and hope. I was chosen for grass, trees and leaves. Look around and you will see me everywhere."

    Blue followed, "You only consider the earth, but look at the sky and the sea."

    Yellow smiled, "I bring hope and warmth into the world. Look at the color of the sun and the moon."

    Orange continued, "I'm the color of joy. My beauty is so fantastic that no one can think of you at sunrise or sunset."

    Red shouted out, "I'm the ruler of you. I'm the color of life and live. So nobody can take my place." Purple stood up, "I'm the color of power. People never question me! They just listen and follow."

    Finally, indigo(靛青色) spoke slowly. "I stand for thought and reflection(反省).Yet all of you just need them."

    Suddenly, the sky became dark and rain started to pour down. The colors all gathered(聚集) in fear. Rain began to speak, "Join hands and come to me."

    The colors did as they were told. Rain added, "Don't you know you each are made for a certain purpose? When it rains, appear together to show that you can all live in peace. The rainbow(彩虹) is the color of your friendship."

    Yesterday afternoon Mr. Brown wanted to catch the 1:30 flight to New York to have an important meeting. At 4:30, Mrs Brown, his wife, got his phone call and he said that he was still at the airport.

    "What happened to you?" Mrs Brown asked in surprise.

    "Well," Mr. Brown said. "Everything was fine at first. I got my ticket checked, took my bags and waited in line to get on the plane. While I was walking across the runway to the plane, I saw my friend Jack Scott—he was a flight attendant. I shouted to him and a policeman caught me."

    "But why?"

    "I don't know. As soon as he heard my shout, he ran towards me and caught me."

    "What did you shout to your friend?"

    "All I said was 'Hi, Jack' ; you know that's the usual way we say hello to our friend."

    "But the sentence 'Hi, Jack' also means to take control of a plane by force(武力). Don't you know?"
