You might have heard about the word "cloud", but not the kind in the sky. This "cloud" helps store your photos, emails, movies, and music. It sounds like something light and soft, but it's actually made up of lots of computers, hard drives, and special cables (电缆).
When you visit a website, you're asking a computer called a server (服务器) to send you information. This information might travel a long way, sometimes thousands of kilometres, from a place called a data centre to your device (设备). It moves through cables buried underground.
So, where are these data centres? In China, many of them are in big cities like Beijing, Shanghai, and Guangzhou. These centres use a lot of space and energy. In fact, in 2018, data centres in Beijing used more than 8% of the city's total energy.
Recently, China has started building new data centres in different parts of the country. Many of these new centres are in places like Ningxia, Gansu, Inner Mongolia, and Guizhou. These areas have lots of land and plenty of green energy, like wind and solar power. Building data centres there can also help these places grow and improve people's lives.
1. What does the "cloud" in paragraph 1 actually consist of?
A. Light and soft clouds in the sky.
B. Underground science museums.
C. Lots of wind and solar energy.
D. Computers, hard drives and cables.
2. How does the information get to you when you visit a website?
A. It comes directly from the website you visit.
B. It travels through cables from a data centre.
C. It comes from some special clouds in the sky.
D. It travels through the air using wireless signals.
3. Why do data centres use a lot of energy?
A. Because they are in big cities.
B. Because they store lots of information.
C. Because they use wind and solar energy.
D. Because they are far from the coast.
4. How can building data centres in new areas help those places?
A. By using less green energy.
B. By providing more computers.
C. By improving local development.
D. By reducing underground cables.
