Mr. Smith made many tests with different animals. They found that the monkey was the cleverest of all the animals. One day Mr. Smith put a monkey in a room. He also put some small boxes in it. In one of the boxes there was some food. “How long will it take the monkey to find the food?” Mr. Smith said to himself. “Let me wait and see.” He left the room and waited outside. Three minutes later, he put his eye to the keyhole (猫眼). What did he see? He saw the eye of the monkey. The monkey was on the other side of the door and looked at Mr. Smith through the keyhole.

    There was once a little orphan(孤儿的)girl who had no family and no one to love her. She felt sad and lonely(孤独的).

    One day, while she was walking in a garden, she noticed a small butterfly caught in a bush. The more the butterfly tried to free itself, the deeper the thorn(刺)cut into its body. The girl carefully helped the butterfly out. Instead of flying away, the little butterfly changed into a beautiful fairy(仙女).

    "For your wonderful kindness," said the fairy, "I will grant(保证)you any wish you like."

    The little girl thought for a while and answered, "I want to be happy!"

    "Very well!" The fairy leaned toward her and whispered in her ear. Then the good fairy disappeared.

    As the little girl grew up, she stayed happy. Everyone asked her the secret(秘密)of her happiness. She would only smile and answer, "The secret of happiness is that I listened to a good fairy when I was a little girl."

    When she was very old and on her death bed, her neighbors were afraid that her secret of happiness would die with her. "Tell us, please," they asked. "Tell us what the good fairy said."

    The lovely old woman simply smiled and said, "She told me that everyone, no matter how secure(安稳的)they seemed, how old or young, how rich or poor, had need of me."

    Everyone has need of you.

    Sally was a student. It was going to be her mother's birthday. She wanted to buy her a gift that would be nice and useful but not expensive.

    A week before her mother's birthday， she went shopping after a quick and simple lunch. When she had been looking for half an hour， she found a shop that was selling cheap umbrellas， and decided to take a black one， since her mother had lost hers the month before.

    She thought， “You could carry that when you are wearing clothes of any color.” So she decided to buy a lovely black umbrella and took it back to school with her until her classes had finished.

    On her way back home in the train that evening， she felt hungry because she had such a small lunch that she went along to the buffet car（餐车） for another sandwich and cup of coffee. She had left the black umbrella above her seat in the compartment（车厢）， but when she got back， it had gone! When she had left the compartment， there had been no other passengers in it， but now there were three.

    Sally began to cry when she saw that the umbrella was no longer there. The other passengers felt very sorry for her and asked what the matter was. She told them that the black umbrella she had bought for her mother was gone， and that she had to get out at the next station. After the three other passengers heard it， they asked her for her mother's address so that they could sent the umbrella to her if someone had taken it by mistake and brought it back after Sally had got out of the train.

    The next week， Sally heard from her mother. It said， “Thank you very much for your lovely gifts， but why did you send me three black umbrellas?”
