    There was a man who had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them to go and look at a pear tree far away in turns.

    The first son went in the winter, the second in the spring, the third in summer, and the youngest son in the fall.

    When they had all gone and come back, he called them together to describe what they had seen. The first son said that the tree was ugly. The second son said no; it was covered with green leaves, and full of hope. The third son disagreed. He said there were many flowers that smelled so sweet and looked so beautiful, it was the most wonderful thing he had ever seen. The last son disagreed with all of them, he said there was lots of fruit in the tree, full of life and harvest（收获）.

    The manthen explained to his sons that they were all right, but they had each seenonly one season in the tree's life. He told them" You cannot judge a tree,or a person by only one season and its true nature —the pleasure, joy, and lovethat come from that life can only be judged at the end, when all the seasons are up."

    If you give up when it's winter, you will miss the promise of your spring, the beauty of your summer, harvest of your fall. Don't let the pain of one season kill the joy of all the rest.

One day, Meg finds that a button(纽扣) of her coat is lost. She looks forthe button everywhere, but she can't find it. The next day, she doesn't wear that coat to school and feels sad all day. After school, she goes to the clothes shops and wants to buy that kind of clothes. But she feels disappointed.

    Meg tells her sister about that, her sister says, “We can change all the buttons. Then the buttons will be the same.” The coat is beautiful again and Meg feels happy again.

    An old man was going home late one night with his horse and cart after a day's hard work. When he was not far away from his house, the light on the cart went out. He tried but could not repair it. He was near his home, and so he went along the road without a light. When a policeman saw this, he stopped the old man.

    "Where is your light?" asked the policeman. "No man may take a cart along the road at night without a light. You know that. You have broken the law." "I had a light, but it has just gone out," said the old man.

    "I don't believe that story. What's your name and where do you live?" asked the policeman. "Please don't write down my name," said the old man. "My home is just there. You can see it from here. I had a light nearly the whole way."

    "You came all the way without a light. What's your name?"

    The old man quickly took the policeman's hand and put it down on the top of the light. The light was still hot and burnt the policeman's hand. The policeman jumped and he was very angry. "Now, what do you think?" said the old man. "Did I come all the way without a light?"

    The robin (知更鸟) stood on an old climbing plant, and sang his most beautiful song. Suddenly the wind made the plant move, and Mary saw something under the dark green leaves. The thick, heavy plant was covering a door. Mary's heart was beating fast and her hands were shaking as she pushed the leaves away and found the keyhole. She took the key out of her pocket, and it fit the hole. Using both hands, she managed to unlock the door. Then she turned round to see if anyone was watching. But there was no one, so she pushed the door, which opened, slowly, for the first time in ten years. She walked quickly in and closed the door behind her. At last she was inside the secret garden!

    It was the loveliest, most exciting place she had ever seen. There were old rose trees everywhere, and the walls were covered with climbing roses. She looked carefully at the grey branches (枝条). Were the roses still alive? Ben would know. She hoped they weren't all dead. But she was inside the wonderful garden, in a world of her own. It seemed very strange and silent, but she did not feel lonely at all. Then she noticed some small green shoots coming up through the grass. So something was growing in the garden after all! When she found a lot more shoots in different places, she decided they needed more air and light, so she began to pull out the thick grass around them. She worked away, clearing the ground, for two or three hours, and had to take her coat off because she got so hot. The robin hopped around, pleased to see someone gardening.

    For years I went to school by bus, so I met many "familiar" strangers. We took the same bus but didn't know each other's names. I used to think it was impossible for us to be true friends. How wrong I was! Smiles from the "nameless" people have changed my thought.

    The first time on the bus, I saw different faces. As days went on, we hatted like old friends.

    But I felt it a pity that I was unable to set up the same friendship with a silent girl in the front of the bus. Her old clothing suggested that she didn't have much money, but she always took a cup of water for the driver. I guessed she was a kind girl. But why did she sit in silence instead of talking with us? Why did she never reply to our friendly greetings? Couldn't she smile?

    Then, one evening, I got the answer. I walked to the park nearby and found the girl sitting alone under a tree, lonely and sad. I greeted her with the same warm smile that had shown to her all these months, but this time her face turned red, then a shy smile appeared. As soon as she began her first words, I understood why she hadn't spoken to us before. Talking was hard for her.

    I heard her story. Her parents worked hard somewhere. She lived with her disabled grandparents. She said, "I can't express myself very well. Most of the time, I can't say what I want to say I have no friends but. You always smile at me like an angel… so I also want to smile." That evening, we exchanged our names and we said goodbye like old friends.

    The smile is the key to opening the door of heart; it can break the cold walls in front of us.
