【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 our 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 of 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.
