Earlier this month, two rock climbers achieved what many thought impossible: They climbed up the 3,000-foot-high Dawn Wall in Yosemite NationalPark without specialized equipment. Climbing without this equipment iscalled“free-climbing.”Until now, no one had free-climbed to the top of the rockface, which is a part of the mountain EI Capitan.

    El Capitan, which means“the captain”or“the chief”in Spanish, has always presented a challenge to climbers. But the Dawn Wall, on the mountain's southeast face, is a particularly difficult route to the summit (顶峰). It is a rock formation that is both steep and relatively smooth. This makes free-climbing the rock face seem almost impossible.

    About seven years ago, professional climber Tommy Caldwell spotted a possible route up the wall. It took years of planning and preparation, but this month, Caldwell, 36, and his friend Kevin Jorgeson, 30, finally make the climb.

    Free climbers do use ropes and other basic safety equipment to catch them if they fall — and Caldwell and Jorgeson fell often. Before starting their climb, they broke down their route into 32 sections. Each section was based on a rope length called a“pitch.”The rope was secured into the rock faceto catch the climbers if they fell.

    Caldwell and Jorgeson's goal was to climb the DawnWall without returning to the ground. If they fell, they had to start that pitch all over again. The two men started climbing on December 27. They slept in hanging tents, and a team of friends brought them food each day.

    The men had spent years rehearsing (排练) them ovements it would take to get through each pitch. They made it through the fist half of the climb relatively easily. But halfway up, Jorgeson ran into trouble. In one difficult spot, he fell each time he attempted to climb. After10 days of trying, Jorgeson finally made it to the next pitch.

    Getting through that troublesome pitch gave both climbers renewed energy. They finished the rest of the climb five days later, on January 14.

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    It was a shock and a painful lesson for many people when the police announced the cause of a bus accident in Chongqing on Oct 28. Video footage (片段) from inside the bus suggested that after a passenger missed her stop and asked the driver to stop, but he refused. She began hitting him over the head with her cell phone. During the conflict, the driver lost control of the bus and it jumped into the Yangtze River, causing 15 deaths.

    Zheng Chuankai, a lawyer in Beijing, said the accident showed that it was important that those who cause danger to public safety face severe punishment. Such attacks are inhuman but common. In fact, it is not rare to hear of passengers attacking bus drivers in China. This month, a local court in Shenyang, Liaoning province, sentenced three people to up to three years in prison for endangering public safety by distracting bus drivers, Xinhua reported. “Passengers who interfere (妨碍) with bus drivers are endangering public safety, which is equal to serious crimes like arson (纵火) and poisoning.” Liu Changsong，a Beijing lawyer, told the Global Times.

To prevent similar cases from happening, many Chinese cities have taken measures to keep bus drivers safe. Dozens of cities including Beijing, Xi'an, Wuhan, Changsha and Nanning have plans to add safety fences to buses to protect drivers from any interference by passengers.

    The bus operator in Quanzhou, Fujian Province, has invited psychologists to teach drivers how to manage their emotions when facing an angry passenger. These measures are necessary, but they are not enough.

    “Public security is closely connected with social morality (道德). People should obey the law, be more self-disciplined and sensible.”

    Many countries have introduced measures to deal with the problem of violence against bus drivers. On every bus in the US state of New Jersey, a sign on the back of the driver's seat warns passengers that anyone attacking a driver can be fined or put into prison.

    In London, the local government has launched a program to train drivers to deal with angry passengers and avoid potential conflicts.

    What will restaurants look like in the future？What would your dinner taste like if a robot cooked it？A robot restaurant in Tianjin may give you the answers.

    Covering an area of over 400 square meters with a total of 112 seats, the X Future Restaurant is a robot restaurant opened in November 2018. The restaurant has amazed customers with its fully-automated(全自动的)technology, which covers every step of the dining experience, from ordering to cooking to serving the dishes and even taking payment.

    Entering the restaurant, one can order dishes by simply scanning(扫描)the QR codes on the table. There are over 40 choices of dishes. After taking the order, "robot cooks"prepare dishes using fixed time, temperature and ingredients designed by famous Chinese cooks.

    "As the cooking is controlled by a computer system, the taste and quality of dishes can be good, "said Li Xiaokui, manager of the X Future Restaurant.

    Robots also complete the delivery of dishes. Without following any designed route, the robot waiters serve meals thanks to automated driving technology, which helps each robot timely change its route when something is in the way.

These eye-catching technologies have received wide praise from customers. "The dishes taste surprisingly good. I couldn't believe that they were made by robots, especially dishes that were difficult to cook" one customer said. "The application of robots has increased our efficiency(效率)and cut down our costs, "Li said, "I think robot restaurants will develop fast and have a bright future. "

I've had many opportunities to experience living in a foreign culture, but my first experience came in an unexpected place—my own country. When I was 20, I got an internship (实习职位) in New York City. It was my first time to 1 outside of my home state of Texas.

With my move north came culture 2 . I grew up in a big city in Texas. But it was no comparison to the tightly 3 New York with their 8 million citizens. I was used to life at a 4 pace; New York moved fast. The saying is true—this city never 5 . I had to adjust.

My first reaction was fear. Fear I would 6 at my new internship in the 54-storey office building. Fear of getting lost on the subway. Fear that the locals wouldn't have 7 for my frequent moments of confusion. My 8 ranged from reasonable to silly. But I 9 my fears and kept trying.

I learned quickly never to 10 a New Yorker always speaks English. New York is home to people of all walks of life, from all corners of the world. At weekends, I would spend hours 11 along Canal Street in Chinatown—the closest I'd ever been to an 12 country.

By the end of my internship, I was a little older, a little wiser and sick of big city life. I 13 the skyscrapers, tourists and the high price I had to pay for a cheeseburger and fries. But I had 14 , too. I was quicker, smarter and more independent. I knew I would miss that feeling of having the world right at my doorstep. But it was good 15 for the life of travel I'd soon begin.

In a normal year, Dayna Reber, a business analyst for a technology consulting firm in Camp Hill, Penn., would finish reading around three books. Thanks to the way Covid-19 has completely changed her daily routine, however, Ms. Reber, 30—who now works from home and rarely socializes offline—has polished off 46 volumes so far in 2020. And that count doesn't include the bedtime stories she reads to her 4-year-old.

For Ms. Reber and others, lockdown has brought back a passion for reading, both as beneficial time-filler when stuck at home and as a trusty escape. "When the coronavirus hit, I just felt a need to get away from TV and screens."

If binge (放纵地) reading hasn't fully replaced binge-watching Netflix shows quite yet, the trend is certainly making strides. In August 2020, year-over-year sales of print books in the U.S. were up 13%, according to NPD BookScan, which tracks book sales across the U.S. Publishers also report a notable increase in purchases of e-books, as well as all books about politics or related to civil rights, racism and diversity.

Independent booksellers, as well as publishers and authors, deserve considerable credit for fueling the page-turning trend. In March, Octavia Books introduced free shipping or delivery within New Orleans on orders of $25 or more. The bookstore also hosts author events via Zoom. And in Illinois, Page 1 Books established a subscription service, where customers fill out an online profile, noting their literary tastes, and then receive a package each month, a mix of hardcovers and paperbacks.

Jamie Miller, 34, a book blogger and "book-stagrammer" who lives in Harleysville, Penn, has long been a committed reader, but she says the hobby has meant far more importance this year. She now schedules a block of time every morning to read, typically a love or vivid novel. "Everything became so chaotic around me that it was just like what can I control?" said Ms. Miller. "My brain just wants something guaranteed to be a happy ending."
