【题目】 Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your mobile phone loses its signal, the television has no programs, and you can't get online with your computer.

What has happened? These are just the types of problems a solar storm(太阳风暴) might cause. You may not think of storms as putting out society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares(太阳耀斑): large explosions(爆炸) near the sun that can give off lots of energy. The strong energy can stop the satellite systems(卫星系统) that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine's Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

“Solar flare activity is going to be much worse than what we've seen in the past. We're not talking about a few cities losing power, it could be half of the country, maybe more.”SolarStormWarning. com, a US website about space weather, warned.

Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

A.call for scientists to predict when the next solar storm will happen

B.tell people how to solve the problems caused by solar storms

C.introduce what solar storms are to people

D.ask people to work to prevent the solar storm

【题目】 Nature's Warnings

When the sky suddenly turns dark and the wind is strong, watch out! A dangerous storm might be coming. Storms are scary. Watch for flashes of lightning. Listen for thunder. If nature sends these warnings, don't wait for rain. Act right away to keep safe.

Safety Steps

At the first flash of lightning, quickly get inside a building or a car. Do not go into a shed(棚) for protection. It is not closed like a building, so it is not safe.

Even after you are indoors, be careful. It is not smart to go near doors and windows. They can blow in or break. A room with no windows is the safest place to be.

Do not wash your hands during a storm. Do not use anything that runs on electricity either. Water and electrical lines are like roads for lightning. Even if you really want to play computer games, don't! It is better to be bored than to risk getting hurt. Try reading a book instead. Reading is more fun than playing computer games.

If_you_can't_get_to_somewhere_safe,_stay_out_in_the_open. You may feel safe under a tree, but that is not a good place to be. Lightning is pulling toward tall poles and trees. Stay down in an open space and cover your ears to protect them. Loud thunder can damage your hearing.

Lightning Strikes

Lightning does not strike people very often. It is not likely that you will ever see that happen. If you do, call 120. Only trained emergency workers should care for a person who has been hit by lightning.

If you follow these rules, you should stay safe during a storm.
