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.
1.According to the passage, a solar storm can cause many problems EXCEPT that________.

From the moment you open your eyes in the morning, you can feel sweat (汗水) running down your body, even if you are barely (几乎不) moving at all. That's what most people in China felt like this summer. In fact, the entire northern hemisphere (半球) saw high temperatures in July.
The Arctic Circle was no exception (例外). Temperatures in the city of Norilsk, which is in the Arctic Circle, reached a record high of 32 ℃, the Atlantic reported. Temperatures there are usually just 10 ℃ at this time of the year.
The heat wave in the Arctic is mainly a longterm result of global warming, according to the Chinese Academy of Meteorological Sciences. In fact, while the whole world is getting warmer, the Arctic is warming twice as fast as the rest of the planet. This is called the polar amplification effect (极地放大效应).
The most direct influence of Arctic warming is the melting of Arctic ice. According to NASA, Arctic sea ice is now disappearing at a rate of 13.2 percent every 10 years. NASA said that if this continues, the Arctic will have no ice by the year 2040.
This has put some Arctic animals, like polar bears, in danger. The ice that the bears live on has shrunk (缩小), the Toronto Star reported.
Melting ice can also cause sea levels to rise in the long term. Since_1993,_sea_levels_have_risen_at_a_rate_of_3.2cm_every_10_years,_the Guardian reported. Some countries, such as Tuvalu (图瓦卢)in the South Pacific Ocean and Maldives (马尔代夫) in the Indian Ocean, are at risk of disappearing into the sea.
