    Would you like to live in a city where buildings turn the light off for you, and self-driving cars will find the nearest parking space themselves? Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think.

Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence” system(远程遥控系统)---allowing users to control the heating and looks, take part in video meeting, and receive education, healthcare and around the city, escalators(自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.

The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.

About 75% of the world's population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener," said Dan Hill, head of a research company.
