In the Charles E. Johnson Elementary School in New York，there is a special radio. （1）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，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. We felt happy about its work，”William Tomic said. “The parents were as well. ”

The US government hopes there will be more such successful 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，1，000tornadoes（龙卷风）and some hurricanes（飓风）take place in the US，so the warning radios are very useful. （2）They not only give people warnings about bad weather，but also give warnings about other dangerous things.
