ROME - China's self-developed large passenger aircraft C919 holds certain advantages over established foreign rivals，a leading European expert in the sector has said.

"It's very early, but we can say that the C919's path to becoming a rival to large and established companies like Boeing and Airbus is not impossible，"said Andrea Giuricin，head of transportation-focused firm TRA Consulting，in an interview with Xinhua.

On May 28，2023，the C919 completed its first commercial flight from Shanghai to Beijing operated by China Eastern Airlines，marking its official entry into the civil aviation market.

The C919 project was launched in 2007. Developed by the Commercial Aircraft Corporation of China Ltd（COMAC），the first C919 aircraft rolled off the production line in Shanghai in November 2015. In 2017，the plane accomplished its maiden flight. 

Giuricin said that the C919's primary advantage could lie in its home-field advantage in China. With China accounting for approximately one-fifth of global air traffic and boasting a growth rate of more than air traffic annually—faster than both the United States and Europe —the country could be on pace to become the world's largest air traffic market by 2050，he noted.

According to L'Usine Nouvelle，a French technology publication, the C919 will be more powerful than the Boeing 737 and the Airbus 320，and it could rival those aircraft in terms of fuel efficiency.

No one shows off a new gadget quite like Apple. But the device that Tim Cook unveiled on June 5th was billed as something more significant. The Vision Pro, a pair of sleek glass goggles, represents"an entirely new spatial computing platform", said Apple's boss, comparing its launch to that of the Macintosh and the iPhone. Apple's message is clear: after desktop and mobile computing, the next big tech era will be spatial computing— also known as augmented reality—in which computer graphics are overlaid on the world around the user.

The presentation was both jaw-droppingly impressive and oddly underwhelming. The Vision is stuffed with innovations that eclipse every other headset on the market. Clunky joysticks are out, hand gestures and eyeball tracking are in. Instead of legless avatars, users get photo realistic likenesses, whose eyes also appear on the outside of the glasses to make wearing them less antisocial. The product is dusted with Apple's userfriendly design magic.

Yet the company had strangely uninspiring suggestions for what to do with its miraculous device. Look at your photos—but bigger! Use Microsoft Teams—but on a virtual screen! Make FaceTime video calls—but with your friend's window in space, not the palm of your hand! Apple's vision mainly seemed to involve taking 2D apps and projecting them onto virtual screens (while charging $3,499 for the privilege). Is that it?

Patience. Mr Cook is right that spatial computing is a new platform, but it will take time to exploit. Consider the iPhone's launch, 16 years ago. Like the Vision, its technology sparkled, but its dull initial uses were inherited from earlier platforms: make calls, write emails, browse the web, listen to music. It was years before developers found mobile computing's killer usecases: group chats, ridehailing, short video, casual gaming, mobile payments and all the other things.

Other platforms have taken just as long to reach their potential. Television producers began by filming people appearing on stage. Internet pioneers started off by sharing files, before spinning the web and much more. Apple's own smartwatch was a damp squib until consumers decided that it was a health and fitness device. It now sells 50m watches a year.

The way to speed up this process is to get the hardware into the hands of developers—and that is the real purpose of the Vision. Apple will not sell many of the expensive first-generation units, and doesn't care. Its aim is to get the product to the people who will work out what spatial computing can do. It is uniquely well placed. Meta, its chief rival in the headset game, lacks Apple's links with developers, who like making software for Apple's bestinclass hardware (and its richestinclass consumers). The flawed but extraordinary Vision shows that the technological struggle to make spatial computing a reality is being won. The next race is to discover what it is for. Apple has just fired the starting gun.

"I'm going to miss you so much, Poppy," said the tall, thin teenager. He bent down to hug his old friend goodbye. He stood up, hugged his parents, and smiled, trying not to let his emotions(情绪)get the better of him.

His parents were not quite able to keep theirs under control. They had driven their son several hours out of town to the university where he would soon be living and studying. It was time to say goodbye for now at least. The family hugged and smiled through misty eyes and then laughed.

The boy lifted the last bag onto his shoulder, and flashed a bright smile. "I guess this is it," he said. "I'll see you back home in a month, okay?" His parents nodded, and they watched as he walked out of sight into the crowds of hundreds of students and parents. The boy's mother turned to the dog, "Okay, Poppy, time to go back home."

The house seemed quiet as a tomb without the boy living there. All that week, Poppy didn't seem interested in her dinner, her favorite toy, or even in her daily walk. Her owners were sad too, but they knew their son would be back to visit. Poppy didn't.

They offered the dog some of her favorite peanut butter treats. They even let her sit on the sofa, but the old girl just wasn't her usual cheerful self. Her owners started to get worried. "What should we do to cheer Poppy up?" asked Dad. "We've tried everything."

"I have an idea, but it might be a little crazy," smiled Mom. "Without anybody left in the house but us, this place could use a bit of fun. Let's get a little dog for Poppy.

It didn't take long before they walked through the front door carrying a big box. Poppy welcomed them home as usual but when she saw the box, she stopped. She put her nose on it. Her tail began wagging(摆动)ever so slowly, then faster as she caught the smell.

Archaeological (考古的) (discover) of Changsha wares (陶器) have occurred randomly over the decades, and key findings of kiln (窑) ruins (make) particularly since 2010. There were not only Tang Dynasty Changsha wares (unearth), but also some celadons (青瓷) from an even (early) period.

They're key witnesses the Silk Road on the sea and Sino-foreign exchanges of material culture. Archaeological findings show that Changsha wares were exported to about 30 countries, (range) from East and Southeast Asian neighbors to North Africa. Craftsmen and workshop owners in Changsha participated in a wave of globalization actively explored overseas markets.

(consequent), shapes of Changsha wares were also influenced by foreign elements. Seeing the antiques, we can also understand  public aesthetics (审美) of their time. They tell  was viewed as traditional Chinese beauty.

I'm a college professor teaching people how to think more creatively. Interestingly, this lifetime passion was 1 by a casual contest when I was a child.

At a family picnic for employees of the company where my father worked, they held a contest for the children-who could throw a cloth handkerchief the farthest. The first 2 , the little ones, took mighty wind-ups(挥臂动作), but when the cloth left their hands, it opened and flew to the ground a few 3 in front of them. The crowd roared with laughter, and being 13, I didn't like adults laughing at us.

It was 4 that using the same technique would not work. Suppose I 5 a rock inside the handkerchief? No, it was "throw a handkerchief", not "a rock and a handkerchief". When they inspected it, I'd be 6 Suppose I hid a rock in the cloth without tying it. The rock would drive the cloth at least farther than the others, and when they 7 , people might not notice a small rock landing in the grass. I had a good 8 of getting away with it(侥幸逃脱).

However, I didn't want to win by cheating but to show the adults that a(n) 9 could beat others at their own game. I had to make the handkerchief fly like a rock. I 10 began tying knot after knot until it was the size of a large rock. I took a long wind-up and threw the 11 handkerchief which landed 60 feet away. The laughing 12 and everyone was dumbfounded. The 13 then ran to fetch it to examine how I'd cheated. "It's just the handkerchief," he 14 , holding it up and untying the knots. The adults applauded kindly and I felt proud.

I hadn't broken the rules, but I had broken the 15 ideas, which was the secret to creative thinking.

The Upside to Being Outside

Research shows that being in nature makes people feel good, whether they're roughing it in the wilderness for days or just hanging out at a local park for a while. One study was conducted in the city of Birmingham, Alabama. Researchers found that most participants' mood and well-being improved significantly when they spent time in urban parks, even though the average visit was only around half an hour.

For example, scientists in the United Kingdom studied the impact of the "30 Days Wild" campaign. It challenged people to interact with nature for 30 days by enjoying earthy activities like feeding birds and planting flowers. Participants were measurably happier and healthier throughout the challenge…and for months afterwards, too.

How does nature boost people's happiness? Scientists say that spending time in natural settings reduces stress and anxiety, which benefits mental and physical health. Research shows our brains are more relaxed in natural settings.

To most people, it's not news that nature can be calming. But multiple studies have found that spending time in nature also has some more surprising benefits, like improving creativity and problem-solving. Another found that exposure to nature helped people score better on tests. That's more proof that going outside is a smart move!

What accounts for the connection with cognition and creativity? It could be that a good dose of nature acts as a cure to information overload. Everyday life involves a lot of multitasking. Some scientists theorize that spending time in nature enables our brains to rest and recover from mental tiredness. 

Naturally, scientific studies don't cover everything that's great about the great outdoors. From recreation and exercise to happiness and creativity, there are lots of upsides to getting outside.

A. One study revealed that people were better at figuring out puzzles after a four-day camping trip.

B. According to many scientific studies, there's a good chance it'll make you happier, healthier, and more creative.

C. What's more, the lift people get from nature is long lasting.

D. Lots of people enjoy fun activities outside, like swimming, riding bikes, or climbing trees.

E. When the only light you've seen all day is the glow of a screen, it might be a good idea to switch it off.

F. This means that whether you're studying or playing video games, heading outside to give your brain a break might help you get to the next level.

G. So, kicking back in a park is a bit like treating your mind to a restful mini vacation.

From composer, musician, and philanthropist(慈善家)Peter Buffett comes, a warm, wise, and inspirational, book that asks, "Which win you choose: the path of least resistance or the path of potentially greatest sailsfaction?"

You may think that with a last name like his, Buffett has enjoyed a life of endless privilege. But the son of billionaire investor Warren Buffett says that the only real inheritance handed down from his parents is a philosophy: Build your own path in life. It is a principle that has allowed him to follow his own passions, establish his own identity, and reap his own successes.

In Life Is What You Make It. Buffett expounds on(阐释)the strong set of values given to him by his trusting and broadminded mother, his hardworking and talented father, and the many life teachers he has met along the way.

Today's society, Buffett assumes, has begun to replace a work ethic, enjoying what you do, with a wealth ethic, honoring the payoff instead of the process. We confuse privilege with material wealth, character with external validation(认可). Yet, by focusing more on substance and less on reward, we can open doors of opportunity and strive toward a greater sense of fulfillment. In clear and brief terms, Buffett reveals a great truth: Life is random, neither fair nor unfair.

From there it becomes easy to recognize the equal dignity and value of every human life our circumstances may vary but our essence does not. We see that our journey in life rarely follows a straight line but is often met with false starts, crises, and mistakes. How we push through and persevere in these challenging moments is where we begin to create the life Of our dreams—from discovering our vocations to giving back to others.

Personal and instructive, Life Is What You Make It is about challenging your circumstances, taking control of your destiny, and living your life to the fullest.

In this digital age, people measure their popularity by the number of "likes" and followers they get on social media. But as it turns out, people are happier when their friends are of high quality rather than huge quantity.

Scientists from the University of Leeds in the UK studied data from two online surveys of nearly 1,500 people. Those who took the survey gave details about their age, social interactions, and how satisfied they were with their social lives. The researchers found that those who had a small number of close friends generally tended to be happier than those who had a large number of superficial (关系浅表的) friends.

"Loneliness has less to do with the number of friends you have, and more to do with how you feel about your friends," said Bruine de Bruin, one of the researchers.

He found that older people tended to have smaller social circles than young people, but the people in these circles tended to be closer to them. He also found that younger people tended to have larger social circles that were made up of "peripheral(次要的) others"— people who are not their true friends, but just the ones they know. These people had no influence on their happiness.

The results of the study show that the opinion society has about old people being sad and lonely might not be accurate.

"The research shows that older adults' smaller networks don't decrease their social satisfaction and happiness. In fact, older adults tend to report a better sense of well-being than younger adults," said Bruine de Bruin.
