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 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. solar flares give off lots of energy
b. people can' t get online with their computers
c. solar storms happen
d. satellite systems are stopped
Crowdsourcing is the process of using many people to perform services. Crowdsourcing explains the saying "many hands make light work" in a new way. At the same time, crowdsourcing follows the old saying that "two heads are better than one". When many people work together on a project, they not only work faster, but they also work better.
There is a community learning website called Memrise, which offers more than 6, 000 free educational courses in all types of subjects. The courses, which are created by volunteers, include photos, videos, games and quizzes to help people learn quickly and have fun at the same time.
You need to know about Crowdsourcing: It is the collection of information, opinions, or work from a group of people, usually through the Internet. It allows companies to save time and money. The advantages include cost savings, speed, and the ability to work with people. |
London's Tate Museum is another good example of crowdsourcing. In 2010, the museum started the Tate Movie Projectwebsite, where children learned how animated(动画的) films are made. The children also wrote stories, drew their own characters and sent them to the website. After that, professional animators worked with the children to compete a film called The ltch oftheGolden Nit. The film was shown on BBC television.

In fact, as students, crowdsourcing can also be a way for you to deal with problems. Suppose your teacher asks you to create a magic story. And you have written a story, but you're not sure whether it's fun or not. What can you do? Just let others around you, your classmates, your parents or someone else, read it and offer their ideas. Then you will collect some wonderful ideas!
What do you think? Is crowdsourcing the way of the future?
