Once a king got two nice falcons(猎鹰)from his son. He had never seen such beautiful falcons before. He loved them so much and he ordered the best falconer to train them to fly.

   After several months, the king came to see how the training was going on. He found that one falcon had already been able to fly high in the sky, while the other was staying on the branch(树枝) of a tree quietly, just keeping still.

   The king called all his falcons together and ordered them to try every way they could to make the other falcon fly. But none of them succeeded. One day, while the king was taking a walk in the forest, an idea came to his mind. Maybe someone who knew the natural environment well could solve this problem. He spent for a farmer who lived in the forest into his palace to train it at once.

   The next morning, the king saw the other falcon flying above in the sky freely. “ it is unbelievable !” shouted the king. How could you make it happen?”

   The farmer replied,“It's very easy. I just cut off the branch where the falcon rested.”

 It is always the same to human beings. We all have “two flying wings” in our hearts as well, but we often seem not to notice them and stay where we just for safety and comfort. We won't realize we can fly so high and freely until the “branch” we are resting on breaks.

    It was July 17th of 2017. The little helpless girl, who had trouble walking, was going out into the wide world. In June 2016, I got the idea that I was going to America as an exchange student. With tears in my eyes, I said goodbye to my family.

    After I finally arrived at the airport in Burlington, Vermont. I was welcomed by my host family. They didn't know much about my disability. “I hobble a little, but I don't see it as a problem.” I think it's the will that decides what you can and cannot do, and the disability doesn't matter!

    Before I went to the US, I knew I was going to miss home. But I went! Why? I've been a fighter ever since I decided not to give up my breath when I was born! My mother wrote my host mom an e-mail and told her about my hard birth so they would understand. I remember clearly after she finished reading it, she came into the room, gave me a big hug and said, “You are a fighter.” My host family supported me so much during the year. In school, small notes were sent out to all my teachers, by e-mail, to tell them about my disability. Everything worked greatly.

    By the end of my year, exchange students were asked to talk about our years. I spoke in front of about 100 people! I was extremely proud of my “speech”. The following day some teachers stopped me and said, “Your speech was the best one.”

    My year in Vermont was the best thing I've done so far! I proved I AM A FIGHTER and that NOTHING IS IMPOSSIBLE!

    John Smith is an old porter. He works at the railway station. Every day he is busy carrying heavy things for passengers（乘客）. He is kind to everyone and always ready to help others.

    One morning, John stood in the station. A train was coming. He was waiting for it. Just then he saw a man running in the station with a big bag in his hand.

    “No train is starting. Why is he in such a hurry?” the old man thought to himself.

    John went up to the man and asked, “May I help you?”

    As soon as the man saw the old porter, he stopped running.

    “Can I catch the 10:35 train to London?” the man asked. He looked worried.

    John looked at him for a few seconds and said, “Well, sir. I'd like to help you, but I can't answer your question because I don't know how fast you can run.” Then he continued, “The 10:35 train to London left five minutes ago. Can you run fast enough to catch it?”

    There was once a rich man who loved his little boy very much. He wanted to try his best to please him. So, he gave him a horse to ride, beautiful rooms to live in, pictures, books, toys and everything that money could buy. But for all days, the little boy was still unhappy. He wore a frown(皱眉) wherever he went. He always wished for something he did not have. The man didn't know how to make his son happy.

    One day, a magician came to the man and said to him, "I can make your son happy and turn his frowns into smiles, but you must pay me a great price for telling him the secret.

    "All right," said the man. "No matter what you ask for, I'll give you." The magician took the boy into a secret room. He wrote something on a piece of paper, and then gave it to the boy. There on the paper came the words: Do one kind thing for someone every day. The boy followed the advice and became one of the happiest boys.

    Only those who stop thinking about their own happiness can be truly happy.
