Thomas Alva Edison is one of the greatest inventors of all times. One of his most famous achievements is the electric light. He tried thousands of times to make a long lasting light bulb. Although the light bulb is not his invention, he is the only one to have made such a successful light bulb. Many people remember him for the invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved(批准) in America.

    We can find his inventions in many fields. In fact, many of the advanced inventions were based on his ideas. He invented a phonograph (留声机),a film picture camera, a ticket recorder and so on.  

    Edison was not a good student at school. But he loved to do new experiments. When he was still a child, he built his first lab to perform his experiments.

      An amazing story of Edison's childhood is that he almost made his servant die. Edison used to think that birds ate insects and these insects might make them fly. So he collected these insects and blended (混合) them to make juice. He then let his servant drink the juice. After drinking the juice, the girl lost her sense. But luckily, she was saved.

    A 15-year-old student who invented a flashlight(手电筒) getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.

    Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.

    Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."

    Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶体管).

    Ann's prize includes $ 25,000 and a "once in a-lifetime expericnce" from Google for her Hollow Flashlight, which has no moving parts or batteries.

    The idea for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.

    In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."

    A video of Ann explaining how she creatcd the flashlight has been watched more than 1.4 million times on the Internet.

    Though Ann was successful, she has not made a decision about her career path. Ann hopes that she can find a way to join her love of film and science together.

    The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

    Three travelers, Allan, Carl and Paul were sitting on the chairs in a train station. They were waiting for a train that was very late.

    To kill time, they began talking to each other.

    At first, they talked about the weather and their work. Then Paul said, "Tell me-what would you most like to do if your doctor tells you that you have only three months to live?"

    The other two men thought about this for a while, then Carl spoke.

    "Well," he said, "if I have only three months to live, I'll take all my money out of the bank and go to foreign countries for holidays with my best friend, Erik. I'd like to travel to the places in the world as many as possible. And I'll stay at the best hotels and then eat the best food. I think I'll have a wonderful time. "

    "That's very interesting." Paul said.

    With these words, he turned to the other man, saying, "And what about you?"

    "I'll tell you a secret," Allan said. "I always want to be a racing driver. So if I have only three months to live, the first thing I'd like to do is to sell my house. With the money I'll buy the fastest car in the world. Perhaps I can enter all the big motor races."

    Then he laughed, "I might even end up world champion (冠军). "

    "Now it's your turn," Allan went on, "If your doctor tell you the bad news, what would you most like to do?"

    "Oh," said Paul with a smile. "__________________________"

    "Haha! Why didn't we think of that?" The three of them laughed together.
