How many times has this happened to you? You're trying to pass a crowded sidewalk. And someone talking or texting on a cell phone slows you down, or worse1you.
What if we could put these multi taskers(一心二用的人) into their own lane, freeing up half of the sidewalk for pedestrians(行人) who are paying attention?
That's the idea behind the new show Mind Over Masses. The show created a separate lane on a Washington, DC sidewalk for those who wanted to look at their phones, while the other lane was for 2 walkers. It was part of a behavior experiment by the National Geographic Channel in the US.
However, the experiment didn't really work 3 it could have because a lot of phone users didn't notice the markings at all. "it's no surprise walkers didn't notice the lanes because they were 4 looking at their phones, "said Yahoo

On March 14, maths and science lovers around the world celebrated a special day: Pi Day.
Pi is to3. 14, but the number goes on endlessly. It is sometimes written in Greek,π. With the help of computers, mathematicians have been able to pi out to over trillion (万亿) decimal places, but there is still no to the number. This makes pi puzzling, even for the most famous scientists and mathematicians.
Pi Day is celebrated around the world on March 14, since how we write this date, 3/14,looks just like the number pi.
For some people, the appeal (吸引力) of Pi Day goes far beyond maths and science. Pi shows uppopular culture. You can see it in movies, comics, music and more. "In modern movies, any time the filmmaker wants to evoke (产生) a sense of mystery, often the symbol pi is used, "says David Blatner, Jewish American writer of The Joy of Pi.

Above all, Pi is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with pi-related games and activities.

ZhangMing, a college graduate from Shandong, created a 9-page"Wechatguide". With drawings and simple words, the step-by-step guide e how to send messages, take pictures and make video calls. Zhang made the guide for his parents. "My parents are getting old. They need an easy way to learn how to use technology, "he said.
Zhang's experience is c nowadays.Worldwide,40percent of parents learn about new technologies, including computers, mobile Internet and social media, from their children, according to a study from the International Communication Association in 2017.
Parents u to teach their kids about almost everything. Now for the first time, the teachers become the students, and the students turn into the teachers.
The c of the roles comes from the rapid development of society and technology says Zhou Xiaohong, a sociology professor from Nanjing University. Zhou said the Internet and other forms of media give children ways to get information b from asking older generations. Therefore, in the age of information, it's possible that children know more than their parents do.
According to the China Internet Network Information Center, 56.7 percent of Internet users and 67.2 percent of social media users in China are under the age of 30. The younger generation u acts as a link between their family and the new environment. But when they teach their parents new technologies, parents can connect to the new world by themselves, noted Zhou.
In Zhang Ming's eyes, teaching his parents about Wechat brings him c to his parents."People can communicate more by using new technology. Why should we keep our parents out? "said Zhang.
In recent years, a number of Chinese technological innovation(科技创新) have been making waves around the world. Among them, four stand out. They are known as "four new great inventions" of modern China. They have made our daily lives more convenient
High-speed trains
China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken China's bullet trains(高铁), according to Xinhua News Agency.
China is currently working on the next-generation bullet trains that will have a top speed of 400kilometers per hour. By 2020, one-fifth of the country's 150,000-km railway network will be used by high-speed trains. This network will link more than 80percent of major cities across China, said Xinhua.
Mobile payment
Mobile payment is turning China into a "cashless society" led by third-party payment companies like Alipay. For example, instead of paying y cash, customers now pay for goods simply by typing a short password into Alipay app on their mobile devices.
Users can also pay their bills through Alipay, such as their water and electricity bills. Alipay also supports cross-border(跨境的)online and in-store payment, which allows users to buy things on international websites and apps.
Shared bikes
Shared bike services started in Western countries. But China has surprised the world with how quickly it has adopted dockless(无桩的)shared bikes.
Unlike traditional bike-sharing method, dockless bikes allow users to simply pick up or park a bike on the street through GPS and smartphone To unlock a bike, you just need to scan a QR code on a shared bike with a smartphone app After you finish riding, you can park it at available parking areas, lock it and pay for ride through mobile payment services.
Online shopping
With around 751 million internet users, China has long been the world's largest and fastest-growing online shopping market.
Online shopping now accounts for 15.5 percent of total retail sales in China, according to Xinhua. Thanks to lower costs and fewer licensing requirements(执照要求),it's easier for sellers to open an online shop in China than a brick-and-mortar shop(实体店)。
It also helped to create jobs of rural areas. In 2016, online shopping created more than 20 million jobs in rural areas, with over 8.1 million running their own online shops, said Xinhua.
