Imagine you are taking a bus home at night. Suddenly your cellphone loses its signal. The television on the bus has no programs. Everything around us black-except for some strange colorful lights dancing in the sky. What is going on?
These are just the kinds of problems a solar storm might cause. Solar storms happen when solar flares (耀斑)break from the sun and travel towards Earth quickly. Actually, since Sept.4, 2017, the sun has burst out two big solar flares, the most powerful ones since at least 2008 according to NASA. They hit Earth on Sept.7.
Normally, Earth is protected by its magnetic field (磁场). But when strong solar storm mix with it, things change. On the one hand, the colourful lights of the aurora (极光)can be seen from the US and Europe, rather than just from polar (极地的)areas. But on the other hand, the storms can stop the satellite systems that control our computers, cell phones and GPS. They can even cause blackouts (断电) for weeks or months.
, but they can put astronauts in danger. Spacewalking astronauts might have only minutes to hide. For this reason, NASA never plans spacewalks during solar storms.
Scientists now have a new tool called EEGGL, which can predict solar storms and hopefully give us warnings when they arrive. As for the recent storm, scientists say it is still too early to know its effect on our technology. They are closely watching for any long-term effects.

Like all big cities, Paris has a traffic problem: lots of traffic jams and lots of pollution from exhaust fumes. So in 2007, the city began a scheme(计划) to improve the situation.
Under the Velib scheme(bicycle freedom), people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour on the bike is free, but if you don’t return it after 30 minutes, you have to pay. But it’s only 1 euro a day or 29 euros a year! The bicycles are heavy (25 kilograms). They are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 metro stations!
Paris is not the first city to have a scheme like this — not even in France. Many years ago, Lyon started a free bicycle scheme. However, not everybody in Paris thinks it’s a great idea. One Parisian said, “These bicycles are only for short journeys. If people want to travel across the city, they won’t use a bicycle; they’ll still use their cars.”
A city spokesman said, “The bicycle scheme won’t solve all of our traffic problems, of course. But it might reduce pollution levels in the atmosphere. Traffic, together with factory fumes, is a big problem. Everyone knows about global warming. We know this is partly because rainforests are disappearing, but it’s also because there’s so much pollution in the world. We can help improve the situation right here. The Velib bikes might help people to lead a healthier life, too.”
“There aren’t any simple answers to traffic problems and pollution in cities,” the spokesman added. “But unless we do something now, there will be more traffic jams and temperatures will continue to rise. The problems in our environment will only get worse.”

2.How much will you have to pay if you use the bike for 45 minutes?
A.29 euros. B.1.5 euros. C.1 euro. D.Nothing.
3.According to the city spokesman, which of the following statements is true?
A.Traffic is not the only cause of global warming.
B.There aren’t any solutions to the city’s traffic problems.
C.Riding bikes is a perfect way to solve pollution problems.
D.It’s better to drive a car than to ride a bike to travel across the city.
