In a world where technology is king, it is getting more and more difficult to keep up with the ‘R’s— VR. AR, MR, (iPhone) XR and the list goes on.
Many people have trouble telling the differences between augmented reality (AR) and virtual reality (VR) . AR and VR mean that we experience something that isn’t there, but it feels like it is. As a result, it is easy for users to be blown away and wonder what is real and what is not. In short, at the heart of AR and VR are two very similar technologies. Both offer experiences to users, most widely used in areas such as online shopping and as part of psychological treatments.
_______ The main difference lies in the way of transport. Simply put, VR ‘transports’ the user to another world instead of the real one. It uses computer technology to create a 3D environment. Users not only view a screen in front of them, but also use as many senses as possible, such as vision, hearing, touch, even smell. VR is used widely in many theme parks, like Disneyland. Imagine opening your eyes and seeing a new world created by the computer all around you; you can move in this environment and even communicate with it. That’s what VR is like. For example, VR has the power to make users feel as if they are falling. So sometimes while playing games, users become nervous and even scared.
AR, does not shut out the real world, but adds digital graphics to a live view often by using the camera on a smartphone. Users would not be ‘transported’ to another world but instead, they would see graphics created by computers with what they see in real life. AR makes it possible to create many interesting apps, such as the navigation. It does not, change the whole view of what users see. unlike VR.
Thanks to new technology and successful games, AR and VR users already have a lot of choices. AR and VR are both powerful technologies which are still relatively new to many users. However, they have already begun to shake things up in the gaming world. The worlds of AR and VR aren’t just here: they’re getting bigger and better by the day.

【推荐1】Hundreds of pedestrians（行人） in Tianjin have been punished so far this year for looking at their mobile phones while crossing the road. The regulation（规定）says that pedestrians who look at their mobile phones while crossing the road first receive a warning or a fine of 50 yuan if they refuse to correct their behaviour.
“The warning is not a simple reminder. It is a legal（合法的） way with a legal punishment notice given to the pedestrians, ” Xing Yi, an official of the government, said. “Those who refuse to cooperate with the traffic police or whose behaviour harms other people will be fined 50 yuan.”
Zhou Xin works in a busy area in Tianjin. He says that he gives such punishment three to five times each day, and that most of the time the legal warning is useful.
“More and more people look at their mobile phones while crossing roads, which raises the risk of traffic accidents, ” said Yang Yingjun, another official of the government. “The regulation is trying to make people pay more attention to safety when they walk.”
Yang said that in 2019, a local university student who was looking at his mobile phone while crossing a road was hit and killed by a large truck. Similar accidents have been reported in many cities, such as Taizhou and Wenzhou, so those cities have similar regulations.
Many people have expressed their support for the regulation. “I think heavier fines should be given to people who look at their mobile phones on the road, ” said a netizen.

ChatGPT, a smart AI chatbot(聊天机器人) tool, has swept the ed-ucation world in the past months. According to a US survey of more than 1,000 students, over 89 percent of them have used ChatGPT to help with a homework task.
Developed by US company OpenAI, ChatGPT is a powerful tool. You can ask it to write stories and emails, create recipes(食谱), translate languages, and answer all kinds of questions.
Some schools in the US, Australia and France have banned the use of ChatGPT. In the US, for example, New York City public schools banned students and teachers from using ChatGPT on the district’s networks and devices(设备), CNN reported.
The move comes out of worries that the tool could make it easier for students to cheat on assign-ments. Some also worry that ChatGPT could be used to spread inaceurate(不准确的) information.
“It does not build critical-thinking(批判性思维) and problem-solving skills, which are necessa-ry for academic(学术的)and lifelong success,” said Jenna Lyle, the deputy press secretary of the New York City Department of Education.
Apart from bans, teachers are making changes to their classes to block the use of ChatGPT. Some college teachers in the US try to include more speaking exams and handwritten papers instead of typed ones. The New York Times reported.
However, not all educators say “no” to ChatGPT. Some Canadian universities are drafting(起草)policies on its use, for both students and teachers. They have no plans to completely ban the tool so far.
Bhaskar Vira, pro-vice-chancellor(副校长) for education at the University of Cambridge in the UK, said that bans on AI software like ChatGPT are not sensible(明智的).“We have to know that AI is a tool people will use,” he told Varsity, the school newspaper of the university. What we need to do is “adapt our learning, teaching and examinations”. That way, we can “have integrity(诚信) while recognizing the use of the tool”.
