How has technology made your life easier？ When you go to a shopping mall， you can enjoy free Wi﹣Fi there． When you want to take a taxi， you can book one with your phone． In fact， all of these things can be seen in a smart city．
The idea of a smart city was first suggested by tech company IBM in 2010．Generally，a smart city is a city that uses digital technology， such as 5G network and the"internet of things"， to save money and energy， and make our lives more convenient．
Cities like Boston， Amsterdam and Copenbagen are already using smart technology to improve public services． In the US cities of Boston and Baltimore， smart dust bins can sense（ 感知） how full they are and tell workers when they need to be cleaned．In Amsterdam，traffic is monitored and changed according to real﹣time data collected from sensors around the city． There are fewer traffic jams．
Smart cities will allow us to save energy． By using sensors and 5G networks to check the usage of water， gas and electricity， city managers can find out how to use these energy better． For example， water and gas pipes（管道） could remind repair workers when there is something wrong． Air pollution could be more closely monitored， too．
What's more， telehealth is used with the help of 5G． Telehealth means caring for patients from far away when the provider and the patient are not in the same place．
One form of this is video meeting with a doctor in real time， the same to a WeChat video call． It will also give older people or those living in the countryside an easier way to see a doctor． There are many exciting apps for 5G tech in medicine． One of them is far﹣away operations． In March， China's first 5G﹣based brain operation was done by a doctor in Sanya，Hainan，who operated on a Parkinson's patient in Bejing．In August， China Daily reported that robots in Beiing performed three operations in Xinjiang，Tianjin and Zhangjiakou at the same time．
Of course， it will take time to build the smart cities of the future． But since we've already seen successful examples， it won't be long until more cities join in． Tech Republic believes that by 2050， about 60 percent of people worldwide will live in smart cities．

The clock struck（敲）eight，but I was still on the bed．I could hear it was blowing strongly．“It must be windy outside，” I thought． I came to the small town a week ago． I sold some clothes to a ten and friends．So I tried to meet the manager and ask him to pay for them．I was out of luck（运气不好）．He went to London and I had to wait for him here．There was no theatre here but a cinema．The films were all too old．I preferred staying in the small hotel to sitting in the cold cinema． Half an hour later，I felt hungry．I had to get up．It was white everywhere and some children were skiing down the hill．On my way to the small restaurant，I saw a boy fall on to a rock （岩石）．I ran to him quickly and carried him to a hospital．Soon his parents came here．Now I knew the boy was just the manager’s son．He thanked me very much and gave me the money after we had a dinner． What was the weather like ？
