【简答题】
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, 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 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 waming radios are very useful. They not only give people warnings about bad weather,but also give warnings about other dangerous things . (一)请根据短文内容,简要回答下列问题. 小题1:What does the special radio give people? 小题2:Why was no one hurt in the school in the storm? (二)请根据短文中所给汉语完成句子。 小题3: (三)请把短文中划线的句子译成汉语。 小题4: (四)请给短文拟一个恰当的英文标题。 小题5:
