People often said Thomas Edison was the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be pleased only because someone said he was a genius. “There is no such a thing as genius,” Edison said. He thought what people called genius was mostly hard work.

     But Edison was a thinker as well as a worker. From his earliest days as a child he wondered about the secrets of nature. He tried to understand them, and then he tried to learn what he could usefully do with them.

     Edison enjoyed thinking. He knew that most people would do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking could give men enjoyment and pleasure.

     Edison could not understand why anyone could not be interested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what idea he had about life. “Work,” he answered, “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    Yesterday was a memorable day for me. I went to a photo workshop and asked to edit a photo. The shop owner listened to my requirements and led me into a room. There what I saw made me kind of shocked.

    In the room stood-a middle-aged man with twisted(变形的) hands. He was holding a camera in a very professional manner.

    I told him my requirements and he replied in a very confident voice, "You just sit comfortably. I will deal with everything." It wasn't at all matching his physical looks. I thought.

    I did what he said, and within 5 to 7 minutes, he clicked my photo, retouched(修饰)it carefully, cut it into required pieces and handed it over to me.

    I was really amazed to see his perfect behavior-he was so quick and confident. I thanked him and had a nice talk with him. He said he loved his job very much. It allowed him to meet different people and of course make a living. Though he was still unmarried, he was sure he was able to find his best half.

    As a disabled person, he could have led his life depending on others. However, he chose to depend on himself and always be confident in himself. He really inspired (激励)me.

    My mother is a teacher, and I grew up with the challenges (挑战) a teacher faces. I often asked her, “Why do you teach?  What keeps you teaching? ”The answer was always the same. “There is always that one child, that one moment that is worth it. ”

    Now, I am a teacher, too. But different from my mother, I teach students challenging activities outdoors. And when my mother asked me the similar questions, my answer was, “It's that one child, that one special moment.”

    One of those moments happened recently. I was working with a group of girls in a four-week programme. Everything went on well through the “Team” events and we were moving on to a “High” one called the Wire(钢索) Walk.

    In the Wire Walk, each girl had to climb up the pegs(木桩) in a tree to a wire, 8 meters high, and then walk across it. Of course, everything was safe for sure. When I asked who would try, a few girls raised their hands, and they finished the Wire Walk with little difficulty.

    But when it was Susie's turn, it seemed that she didn't really want to. I asked Susie if she was ready. She answered softy, “I suppose.”

    Now, Susie was at the foot of the tree. She started to make the long reach for the first peg. The other girls cheered for her. Then I found Susie was becoming nervous with every step. I realised she would not go much further.

    Susie was halfway up. Then she stopped and held the tree tight(紧紧地),  looking very afraid. Her eyes were closed. With her face against the tree, she cried, “I can't.”

    The other girls sat in silence. I talked quietly to Susie, trying to relax her. I talked for a long time till I ran out of words.

    “I will still be your friend no matter what, Susie!” Mary broke the silence.

    To my surprise, Susie lifted her head and looked up to the wire. Then she turned to look down at Mary and smiled. Mary smiled back.

    Finally, Susie made it all the way across that wire. When she returned to the ground, the first hug she looked for was from Mary.

    We all cheered.

    Moments like this keep me doing what I do. The young hearts continue to fill me with courage.

    There are three brothers in the pop group "The Bright Shiners"：Harold Fisher, Roger Fisher and Dove Fisher. Harold is the boy who formed the group a year ago and he is the leader now. He plays the piano. Roger plays the lead guitar and Dove is the drummer. Then there is Pete Lennox, their cousin. He is the only member of the group who has had much experience. He played the guitar and sang with "The Tower of London" for three years. Alex Clark and Clive Hicks play the trumpet(喇叭). Robert Lester is the boy who has helped the group most. He was born in Chile and he can play five different Andean instruments. Geoffrey Baker plays the harp(竖琴). Bill Blake isn't a musician, but he is an important member of the group. He looks after their electronic equipment.

    A teacher asks his students to write about their dreams. One boy writes seven pages. He wants his own farm and a large house on it. But his teacher tells him, "You are daydreaming. Do it again." Several days later the boy hands in the same article, saying, "I don't want to give up my dream even if you fail me." Years later, he makes his dream come true. One day, the same teacher takes some students to the boy's farm for camping. Seeing the big farm, the teacher feels sorry, "I once told you not to daydream. Luckily, you never gave up."
