  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. 3               (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. 24They not only give people warnings about bad weather, but also give warnings about other dangerous things.请根据短文内容,简要回答下列问题.

1. What does the special radio give people?

                                             

2. Why was no one hurt in the school in the storm?

                                             

3.请根据短文中所给汉语完成句子。

                                             

4.请把短文中划线的句子译成汉语。

                                             

5.请给短文拟一个恰当的英文标题。

     Have you ever wondered?

     Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.

     What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.
