Look at the light and beautiful snowflakes (雪花) falling. Ever wanted to hold them in your hands? They are always lost when they meet your hands.

    Well, this isn't just a problem for you. It was a problem for Wilson Bentley, too. In the 1870s, Wilson Bentley was just a teenager. His family lived in a small town in northeast America. Winters there were long and hard. Bentley's mother was once a school teacher. She taught him at home. Bentley didn't go to school until he was 14. He was a quiet boy, and loved reading his mother's books. But he was interested in his mother's microscope (显微镜). When the other boys were playing with balls, little Bentley was studying things like drops of water, flowers and snowflakes.     

    Bentley loved watching snowflakes. For the next two years, young Bentley spent many winter days in a cold room watching these ice crystals (晶体) under his microscope. The boy thought they were beautiful enough for him to start to draw pictures of them. But there were so many snowflakes that he couldn't draw them all.

    How could he keep their beauty all the time? Bentley thought of buying a camera.

    The boy and his mother asked his father to buy one. But, his father didn't agree. He thought the whole thing was a bad idea. He thought the only thing a farmer should do was farming.

    But finally Bentley did get a camera. For more than a year he tried to take pictures of snowflakes. On January 15, 1885, during a snowstorm, Bentley took the first ever photo of an ice crystal with his camera. “It was the greatest moment of my life,” Bentley said later.

    For 13 years, Bentley worked quietly and took thousands of photos of ice crystals. Later he became famous as “Snowflake” Bentley.

    When I was in high school.I worked part-time helping Dad sell fruits and vegetables at a matket. One day，as I was preparing the fruits. A little boy came by with his mom and sister. He was  about eight years old，and the girl.five or six. They were looking the fruits in front of me. I heard the kids say to their mom(in French),"They're good!" I knew it was French. Because I can speak and understand it.

    Then I noticed how mom was picking the fruits.At first I thought she was really looking at the fruits because she was facing them. But then I noticed how much she had to feel and smell each one as she picked them out. And often asked her son if it looked okay, but looked way above where his face was. Putting what I saw together,I was sure she was blind.

    Both of the kids continued to help their mom pick out the fruits .The son made sure the fruits were not obviously bad, and the daughter handed them to her mom. The woman then felt each one and smiled, and the daughter would put them into their basket .The kids were smiling while helping their mom pick the fruits out.

    Their smile and gentle manner moved me in a way that never happened before .It was so beautiful to see such young kids so willingly help. Most kids that age would be picking out candies or toys in a store for themselves, instead of helping their mom pick out fruits as the two kids did.

    It was great to witness the moment, but not so great because I didn't tell the mom how beautiful her children were in their language .this is what I regret to this day.

    When Mr. David retired（退休）, he bought a small house in a village near the sea. He liked it and hoped to live a quiet life in it. But to his surprise, many visitors came to see his house in summer holidays, for it was the most interesting building in the village. From morning to night, there were visitors outside the house. They kept looking into the rooms through the windows and many of them even went into the house. He decided to drive the visitors away. So he put a notice on the window. The notice said, "If you want to satisfy your curiosity（好奇心）, come in and look around. Price twenty dollars. "Mr. David was sure that the visitors would stop coming, but he was wrong. More and more visitors came and Mr. David had to spend every day showing them around his house. "I came here to retire, not to work as a guide（导游）, "he said angrily. In the end, he sold the house and moved away.

    “Everything happens for the best, (一切都会变好的)" my mother said, whenever things weren't going my way. "Don't worry. One day your luck will change."

    After I had finished my college education, I discovered that Mother was right.

    I had decided to try for a job in radio. I wanted to host a sports program. I went to Chicago and knocked on the door of every station. But I got turned down every time. In one station, a kind lady said my problem was that I hadn't got enough experience. "Get some work in a small station and work your way up, "she said.

    I went back home. I couldn't get a job there, either. I felt really down. “Your luck will change, " Mom said to me. I tried another radio station in lowa. But the owner told me he had already had someone.

    As I left his office, I asked, "How can someone be a sports announcer(播音员)if he can't get a job in a radio station?" I was waiting for the lift when I heard the man call, "What did you mean? Do you know anything about football?" He put me in front of a microphone(麦克风)and asked me to try to imagine that I was giving my opinion on a football game.

    I succeeded!

    On my way home, Mom's words came back to me, "One day your luck will change, Son. And when it happens, you'll feel doubly good because of all the hard work you've done." At that moment I knew just what she meant.

    Mrs. Smith is a teacher. Her house is not far from her school and she walks to school every day. All the students like her. Mrs. Smith walks to school on a very cold and windy morning. The cold wind cuts her face, and big tears go down her face. She arrives at the school and goes into the classroom. It is nice and warm there and Mrs. Smith is happy. But then a small boy looks at her and puts his arms round her and says, "Don't cry, Mrs. Smith. We all love you."
