    U.S. Senator Gaylord Nelson first thought of the idea for Earth Day in 1962 when he saw polluted rivers and cities with smoke. He needed to get support from Americans to clean up the earth. Finally, on April 22, 1970, 20 million Americans celebrated the first Earth Day! Now many countries around the world celebrate it, and you can, too.

阅读下面短文，根据其内容完成后面各项任务
    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 Tom, principal（校长）of the school, 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 Tom said. “The parents were as well.”
    The U.S. 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 tornadoes（龙卷风）and some hurricanes（飓风）take place in the U.S., so the warning radios are very useful. They not only give people warnings about bad weather, but also give warnings about other dangerous things.
