根据材料内容简要回答下列问题。

    In the Charles E. Johnson Elementary School in New York, there is a special radio. It gives people warnings (警报) about bad weather.

    One day, there came a sound from the radio. This sound brought the piece of news: a heavy storm was coming. William Tomic, principal (校长) of the school, he asked teachers to bring children indoors and put them in a safe place at once.

    Minutes later, the storm came. However, because of the warning of the radio and the quick work of the principal, no one was hurt. “The radio really did work very well. 我们对它的工作感到很高兴,” William Tomic said. “The parents were as well.” The US government hopes there will be more such success stories. It plans to give this kind of radios to all 97, 000 public schools in the country.

    Every year, more than 10,000 big thunderstorms, 2,500 floods, 1,000 tomatoes (龙卷风) and some hurricanes (飓风) take place in the US, so the warning radios are very useful.

    They not only give people warnings about bad weather, but also give warnings about other dangerous things.

    Jack London was born in San Francisco in 1876. Life was hard when Jack was growing up and he started working when he was 10. He did lots of different jobs. In his free time he went to the library and he spent many hours there, reading. In 1894 he went back to school, and published his first short story Typhoon, off the Coast of Japan. Then in 1896 he went to the University of California at Berkeley, but he had to leave because of money problems.

    In 1897 he left for the Klondike Gold Rush in Alaska. However, he became ill and came home and started working as a full-time writer. He wrote short stories and soon he was well-known. In 1903 he wrote his most famous story: The Call of the Wild.  His next novel was The Sea-Wolf (1904) which is perhaps his best literary novel.  With the earnings he bought a large farm in Califonua, where he died in 1916, aged only 40 years old.

    London was a prolific writer in his short life.  Between 1905 and 1916 he published 18 novels and six collections of stories, as well as a play, various works of non-fiction and a biography.  He is best-known for his descriptions of nature and the animal world.

    We all have our own ways of sharing our life experiences with others.

    Photographers use cameras, artists use brushes, musicians use songs and writers use stories.

    Spencer Johnson's story Who Moved My Cheese? shows changes exist in(存在于) our life. Life changes and so do we. We must change ourselves to face the changing environment, or we will fail.

    Just look at the cycle (循环) of        Trees bud (发芽)in spring and in summer their leaves turn green. In autumn, their leaves start to fall onto the ground. When winter arrives, there are no leaves on trees. Next spring the cycle begins again. Since we know there are cycles in nature, we can prepare for them. We know it is colder in winter and hotter in summer, so we can dress properly.

    Since we accept the cycles of nature, we should also accept the changes in our life.

    We can prepare ourselves for changes by becoming more flexible(灵活的).We can regard the changes in our life as chances. As long as we keep changing ourselves, we can keep up with the changes in our life.
