More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment(环境). Maybe that’s why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

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．

New trains run across rocky mountains and the Great Wall to the north of Beijing like bullets（ 子弹）．They run on a high﹣speed railway line between Beijing and Zhangjiakou． The opening was on Dec 30，2019．
The railway is an important support project for the 2022 Winter Olympics． The 174﹣km railway's trains move at a top speed of 350 km/h． This reduces the travel time between Beijing and Zhangjiakou， the Winter Games will be held there， from over three hours to only 47 minutes． It has 10 stops in total．It will help improve tourism． There are places of interest nearby．
Some of the trains on this railway are smart trains that can run by themselves．
With the help of the Beidou Navigation Satellite System， they can automatically（ 自动）start， run between stations， change their timing according to the time table， correctly stop at a station， and open and close their doors． Passengers can also watch live sports programmesduring the Winter Olympics on the train， which is helped with 5G technology．
Some people consider Zhan Tianyou as "the father of China's railways"． Who is Zhan Tianyou？ In 1872， the Qing government chose 30 young boys to be sent to the US to study．They were the first students in Chinese history to study abroad． Zhan Tianyou was one of them．After graduating from Yale University， Zhan came back to China． In 1905， the Qing government decided to build a railroad between Beijing and Zhangjiakou． Zhan， who studied engineering， led the project． The project is best known for its Y﹣shaped switchback（人字形坡路）．There are many mountains along the Being ﹣Zhangjiakou railway． It was difficult for trains to climb the mountains．
He led construction（建设）on the old Bejing Zhangjiakou railway， China's first independently ﹣designed railway． It was not possible to build a railway without foreign help at that time． But Zhan， the head engineer of the railway project， insisted（坚 持） that it could be done． Zhan came up with an idea to reduce the slope（坡度）：a Y﹣shaped switchback．Instead of going directly from A to B along a steep（ 陡的）slope， the train goes from A to C first and then from C to B． This makes the slope much less steep．
After many difficulties． the Beijing﹣Zhangjiakou line went into operation in 1909． Its trains ran at 35 km/h．
