1 . Cities are difficult to navigate (导航) at the best of times, but for people with disabilities they can be like courses with hurdles and bring inconvenience to disabled people.
A UK national travel survey found that adults with mobility difficulties took 39% fewer trips than those with no disability in 2017. Yet that could change as devices and cities grow smarter. Assistive tech is playing a big role in the transformation. The global value of the industry is expected to increase from $14 billion in 2015 to $30.8 billion in 2024, according to Zion Market Research.
One of the things that could transform lives is a smart walking stick designed by engineers from Young Guru Academy (YGA) in Turkey. The WeWalk stick has a sensor that detects hurdles above chest level and uses vibrations (振动) to warn the user. It can be paired with a smartphone to help navigation, and is connected with a voice assistant and Google Maps.
Ceylan, who has been blind since birth, says that connecting the stick to the Internet of Things and smart city solutions makes it user-friendly. “As a blind person, when I am at the Metro station I don’t know which is my exit ... I don’t know which bus is approaching ... which stores are around me. That kind of information can be provided with the WeWalk,” he says.
“The smart walking stick is really an exciting initiative that will make a huge difference to some people,” says Anna Lawson, the director of the Center for Disability Studies at Leeds University in the United Kingdom. “But they are very expensive ... they’re not going to be available to the vast majority of disabled people,” she added.
Bryan Matthews, a lecturer at the Institute for Transport Studies at the University of Leeds, shares the concerns about cost. He says there should also be a focus on inclusive design, and anything that helps people navigate their environment is positive.

4 . Diplomacy (外交) is an art. It requires not only strategy, but also other aspects, including intuition, persuasion, and even tricks, human skills that have long been unreachable to even the most powerful artificial intelligence (AI) approaches. Now, an AI algorithm (算法) from a high-tech company has shown it can beat many humans in a game of diplomacy, which required both strategic planning and negotiations with other players. The work, researchers said, could point the way toward virtual exercise coaches and conflict mediators (调解员) .
AI has already beaten humans in some games of strategy. It is also proving powerful at natural-language processing, in which it can generate humanlike text and carry on conversations. In the game of diplomacy, seven players vied for control of Europe. On each turn, players issued orders regarding the movement of army and naval units, following discussion with other players, whom they could attack or support.
There are two technical innovations noted by Jonathan Gratch, a computer scientist at the University of Southern California who studies negotiation agents. First, the Al agent’s com-munication is grounded in multistep planning. Second. the Al agent keeps its remarks and game play within the range of human common practice.
To test its skill, the researchers had the Al agent play 40 online games against humans. It placed in the top 10% of players who’d played at least two games. “In a game that involves language and negotiation, that agents can reach human equal level is very exciting,” said Yu, a computer scientist at Columbia University.
According to Brown, a computer scientist at the company who co-authored the paper, the work could lead to practical applications in fields that now require a human touch. One specific example is that virtual personal assistants might help consumers negotiate for better prices on plane tickets. Gratch and Yu both see opportunities for agents that persuade people to make healthy choices or open up during therapy.

7 . How to prepare for a thrilling hike? Hiking needs mental and physical preparation weeks before the material day. If you’re a fan of hiking mountains. Here is a guide to help you.
Train hard and train in timeYou need to train your body at least three months before the challenge.
You must consider various factors before purchasing the most appropriate hiking shoes. First, mind the terrain (地形) of the hiking ground. A mild terrain will do fine with light shoes. On the other hand. A tough, hard and mountainous terrain require hardy hots to help navigate the rocky grounds.
Adequately pack your bagYour bag is your lifeline when hiking. Water is the most essential itch when hiking. The body performs best when you hydrate frequently throughout the challenge. Carry adequate clean water and sip often.
Hiking is a refreshing way of keeping fit, having fun and building resilience.
A.Choose appropriate footwear |
B.Search for the route you will he hiking |
C.Carry a compass, a map and a gas with you |
D.Adequate water can help you be in good con lit ion |
E.create a regular schedule and be disciplined to follow it |
F.Wear appropriate clothes that allow your free movement |
G.Adequate planning will help have a fantastic experience of it |
8 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”
Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.
The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.
“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.

10 . You start by running around the school track three times to warm up. This is followed by exercises or long jump for the girls and football or basketball for the boys. That is an average 45 -minute PE class— but do you really enjoy it?
For students at the Second High School Attached to Beijing Normal University, sports classes have experienced a welcome change. Senior 2 students now learn the traditional Chinese martial art of sword-fighting (中国剑术), making PE the most popular lesson on the timetable. “The classes used to be boring as we just did the same things again and again,” said Xiao Tong. “But now PE classes are such fun. Sword-fighting is so cool.” His classmate Wei Jie agrees. “As well as being fun, we learn about traditional Chinese culture,” she said. The usual morning exercises performed to music on the school playground have been replaced by kicking and punching practice (搏击操) to a pop music by Zheng Xiuwen. “We didn't pay much attention when we heard the old music,” Xiao explained, “But when Zheng's music is played, we get excited.” Mao Min, the PE teacher who introduced the changes, is pleased that the students now enjoy sports lessons more. “The classes encourage healthy lifestyles and I am always looking for creative ways to keep the students active,” he said. Schools offer activities according to what sports facilities (设备) they have. For example, students at the Experimental High School Attached to Beijing Normal University can choose to learn swimming, taekwondo (跆拳道) or volleyball. “I take my volleyball very seriously so I keep fit by playing it,” said Senior 2 student Zhang Zheng. “Students only try hard in sports that interest them.”
