Martin Strel swims with a knife （fasten） to his right leg—in case he meets sharks and other （dead） sea life in the world' wildest waters. 61-year-old marathon swimmer has announced the （tough） challenge of his life: a

10.000-mile-around-the-world journey on water （draw） public attention to the increasing water （pollute）. He aims to circle the globe in about 450 days, passing through oceans, rivers,  （canal） and other bodies of water in more than 100 countries. He will swim about 5 to 12 hours each day, depending on the weather. A boat will go  him and offer emergency support and space for small breaks.

Since 2000, Strel （swim） the entire length of five rivers in China, America, etc. Strel will not be alone in the water. He says he welcomes  is interested in joining him for parts of the route.

Little Oliver was Mason and Rebecca's miracle child. Rebecca suffered three miscarriages（流产） before Oliver was born. When they were still in extreme 1 , Rebecca accidentally found the little boy never reacted to any sound. After examination it was confirmed that Oliver was born 2 .

Facing such a blow, Mason and Rebecca never felt 3 . A few weeks later, Oliver got his first hearing aid. Despite several 4 , Oliver could at last hear! Rebecca and Mason were delighted.

Three years passed, and it was time to send Oliver to 5 . But the first day Oliver returned home 6 ."I don-don't want to go to school... I have no friends..."

One day, Rebecca and Mason were called to the school, where Oliver's teacher, Sophia told them Oliver never 7 with his classmates. He was afraid that his classmates would 8 him over his deafness. Though Sophia talked to him again, he was 9 to communicate.

Rebecca and Mason told her their son was 10 for friendship inside' Sophia decided they had to do something to help Oliver out of his 11 . They made a plan and put it into action on his sixth birthday. Oliver 12 his classroom and found it decorated with balloons. He was surprised and sat in his chair, 13 what was happening. Suddenly, all his classmates marched inside. They all wore colorful birthday caps and smiled at him. Oliver's eyes rose with tears as he watched them sing a happy birthday song in 14 . They had learned sign language to surprise the birthday boy and make him feel 15 . Oliver was touched. It felt like heaven to be surrounded by friends.

A robot with a sense of touch may one day feel "pain"， ‘both its own physical pain and sympathy-for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.

Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up（连接） to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial "pain nervous system"， as Asada calls it, may be a small building block for a machine that could experience pain. Such a feeling might also allow a robot to "sympathize" with a human companion's suffering.

Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic-looking child's head, these touch and pain signals can be converted to emotional facial expressions.

A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin "allows the possibility of engagement in truly intelligent ways".

Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care' for people in need, the elderly, for instance. But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that's capable of approximating an internal feeling, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is "along the lines of having a robot, for example, that smiles when you talk to it," Damasio says.

"While that's an interesting development, it's not the same thing as a robot designed to express somesort of internal experience," he says.

I live in Xizhou in Yunnan Province, on the historic Tea Horse Road, I have to admit that when I first heard that Paul Salopek was going to walk the entire globe on his own two feet, I was blown away, I couldn't imagine that there could be such an unusual person in the world.

Last May, I met Paul, He told me that it was his first time in China. He talked to me with great excitement about the history, migrations, and discoveries in my region of China, He spoke of the Shu-Yandu Dao （the Southern Silk Road）， the travels of the 17th-century Chinese explorer Xu Xiake, the Tea Horse Road and. the early 20th-century American botanist Joseph Rock. He also talked of Xuanzang. Paul considered many of them heroes and in a sense Chinese pioneers of slow journalism.

I decided to accompany Paul on his walk toward Yunnan. On September 28, 2021, we set out. Our days were simple: walk, eat, sleep, and repeat. We woke up at sunrise, set off in high spirits, and rested at sunset, dragging ourselves into exhausted sleep.

We met many people on the road. Some were curious, surrounding us and watching us: some gave us directions; some invited us into their home to take a rest; some. spoke of the charm of their hometown. We met many beautiful souls, simple souls and warm souls. We were walking with our minds.

Together, we were impressed by the biodiversity of the Gaoligong Mountains. As I walked on ancient paths through mountains, I seemed to hear the antique voices of past travelers urging me to be careful on the road.

Looking back on the more than 200 miles I walked, with Paul, I came to a realization, Walking for its own sake, while healthy and admirable, is only a small part of the benefit of moving with our feet, A deeper reward is rediscovering the world around us, shortening the distance between each other, and sharing each other's cultures.

In 1926, US automaker Henry Ford shortened its employees' workweek from six eight-hour days to five, with no pay cuts. It was something workers and labor unions had been calling for. Ford wasn't responding to worker demands; he was being a businessman. He expected increased productivity and knew workers with more time and money would buy and use the products they were making. It was a way of encouraging consumerism and productivity to increase profits, and it succeeded.

Since standardization of the 40-hour workweek in the mid-20th century, everything has changed except the hours. If anything, many people are working even longer hours, especially in North America. This has a severe influence on human health and wellbeing, as well as the environment. Until the Second World War, it was common for one person in a family, usually the oldest male, to work-full-time. Now, women make up 42% of the world's full-time workforce. Technology has made a lot of work unnecessary, with computers and robots doing many tasks previously performed by humans.

Well into the 2lst century, we continue to work the same long hours as 20th century laborers, using up ever more of Earth's supply to produce more goods that we must keep working to buy, use and replace in a seemingly endless cycle of hard work and consumption. It's time to pause and consider better ways to live like shifting from fossil-fueled lifestyles with which our consumer-based workweeks are connected.

The UK think tank, New Economics Foundation, argues that a standard 21-hour workweek would address a number of interconnected problems: "overwork, unemployment, over-consumption, high carbon emissions, low well-being, and the lack of time to live sustainably, to care for each other, and simply to enjoy life".

Economic systems that require constant growth on a finite （有限的）planet don't make sense. It's time for a change in our economic thinking.
