Pete is one of the kids who, for nine and a half minutes each day, have to3 here to change buses. The station smelled strongly of gas, and the nearby land, once possibly a garden, now lay4 with trash—cans, wrappers, and chicken boxes. Most kids5 their time complaining, but Pete felt restless. He began to think: why not make these minutes6 for him and others.

One Monday, he arrived with bags and gloves. As he piled the7 into bags, his classmates teased: ‘Why8 yourself? It'll just get dirty again!" But Pete persisted. On the weekend, he dragged 12 bags to the landfill.

Next, he spent pocket money on tulips and lavender (薰衣草) seeds. Each day, he9 the soil and watered seedlings. Slowly, green shoots emerged. Teasing turned to awe when blossoms10 color to the cheerless corner. Kids began using trash bins; some even11 to help water.

One afternoon, an elderly man12 Pete. "I used to garden here decades ago." he said, handing Pete a watering can. "You've13 its soul."

Now, "Pete's Patch" thrives. What was once14 is now a symbol of community pride. Pete's story proves that small acts, if patiently nurtured, can grow into something15 .

The more extreme concerns around AI involve what's known as the singularity. In his 2010 paper The Singularity: A Philosophical Analysis, the philosopher David Chalmers describes the singularity as follows: "What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now known as the ‘singularity'." The main worry is that, if such a singularity event were to occur, we'd no longer have authority over what happens in society.

While influential figures across AI research express real concern about the singularity, however, American philosopher Daniel Dennett doesn't buy it. As he puts it, "I am not worried about humanity creating a race of super-intelligent agents, but that does not mean I am not worried. I see other, less dramatic, but much more likely, scenarios in the immediate future that are cause for concern." He argues that smart technology presents us with more practical threats that have a far higher likelihood of occurring. As Dennett clarifies: "The real danger is not that machines more intelligent than we are will usurp (篡夺) our role as captains of our destinies, but that we will overestimate the comprehension of our latest thinking tools, easily ceding (让渡) authority to them far beyond their competence. "

Take transport. It's not just aviation and shipping industries that depend on GPS for safe and efficient navigation: how many individuals now turn to their smartphones instead of using a road map? As Dennett summarizes: "Use it or lose it is the rule of thumb cited at this point. . . how concerned should we be that we are dumbing ourselves down by our growing reliance on intelligent machines? "

Anti-Atlas Mountains

Extending from the Atlantic coast to the edge of the Sahara and with a huge variety of terrain, the Anti-Atlas Mountains cater for even the most indecisive traveller. Above all, Anti-Atlas is agadir country (the word means wall) . The landscape is dotted with these remarkable walls. Built from stone and clay, they were typically set on hilltops or cliffs to provide protection from attack.

The Mediterranean coast

Unlike Morocco's Atlantic coast, the country's Mediterranean coastline is a less well-known destination. Of all the beaches in this area, Plage Ihttpye n is the best. Hidden from view behind two enormous red cliffs east of Port Sidi Hsaïn, and accessible only by a steep rocky path, it's an incredible peaceful and picturesque spot, with crystalline waves lapping against the pebble shore and curious rock formations rising from the waves.

Agadir

Founded in the 16th century by the Portuguese, Agadir quickly became a booming trading post, growing rich on the profits of sugar and spices. In 1960, an earthquake destroyed most of the city and paved the way for its rebirth as a tourist resort. This is the place if you're seeking sun, sand and surf; the coastline around Agadir is the heartland of Morocco's surf scene and you don't have to look far to discover quieter surfing beaches.

Merzouga

Located at the edge of the Sahara's shifting sands, Merzouga has become one of the main desert centers for travellers. The drive there involves a dramatic journey over high mountains and remote river valleys, a panorama (全景) outshone only by the view at the end of the road: the soaring dunes of Erg Chebbi stand in magnificence on the horizon. Climb to the top of the 150-metre-high dunes after the winter rains and you can gaze down on to Merzouga Lake, a watering hole frequented by a colony of flamingos (火烈鸟) and occasional camel herders.

Years ago, someone gave me a little cutting, and I grew a beautiful plant from it, with small, tear-shaped leaves hanging over the edges of the pot.

However, the leaves turned brown and drooped (垂落) so much in winter. Unwilling to give it up, I brought what was left to my mom and asked if she could bring it to life. She just smiled and took the pot from me.

My mom carefully trimmed (修剪) the stems, watered the few surviving parts, and helped the hidden leaves reach the sunlight. The next year, the plant came back to life with fresh green leaves for a few months but withered (枯萎) in winter again.

As the plant grew over years, my mother's health kept getting worse. There were good times and bad times, just like the plant's seasons. Mom told me everyone has "good seasons" and "hard seasons", and life always finds a way to begin again. Just be patient and keep trying when things seem hopeless.

One late winter, when both Mom and the plant were struggling, my Aunt Marion visited. Mom gave her the dying plant to care for. She took it home, determined to help it live .Amazingly, that summer, new leaves grew from the bare plant on her kitchen windowsill. As before, each winter it withered, to be renewed again in late spring. This cycle continued for years until one spring when Aunt Marion thought it was truly dead and threw it away. But my cousin Carole saw the dried plant in the trash and decided to try saving it. She took it to her sunny room. Four women in our family have cared for this plant at different times.

Years later, Mom passed away and I moved far away for a fresh start. Three years later, terribly missing all the relatives, I went back to visit and stayed with Carole.

Years ago, Photographer Ren Peng, visited the hometown of his friend Gu Yan, a member of the Lisu ethnic group, in Yanbian County, Panzhihua City, Sichuan Province. Ren (impress) by the labor-consuming traditional techniques of making Lisu costumes, a kind of provincial-level intangible cultural heritage.

Leaves of fire grass, special plant that often grows in southwestern China, are used to make the costumes. "The whole process has over 20 procedures and takes 8 to 12 months to complete, during over 10,000 leaves are required to make just one costume," says Ren.

With excellent breath ability and resistance moisture (水汽), the clothes made from the grass are (high) suited to Lisu peoples' lives in the mountains.

However, the high-level skills and carefully (craft) products are now less recognized. (draw) greater public attention to this valuable cultural heritage, Ren and Gu organized a fashion show themed on Lisu clothing at the China Fashion Week in Beijing recently.

"The show not only displayed traditional handmade Lisu costumes, but also haute couture (高档女子时装) and ready-to-wear (item) inspired by Lisu clothes," says Ren. He highlights a pair of pants which imitate (模仿)traditional Lisu group's pants with very wide legs just like skirts, but the pant bottoms are tied tight by bands for protection from insects and (convenient).

Moreover, many of the sets of clothes showcased by the models featured a distinctive hat formed by a long cloth tied around their heads, (reflect) the traditional headwear of the Lisu people.

Most people know someone who seems to make every situation a negative and unmanageable one., as they likely don't see a problem with their behavior. Here are tips to help you navigate interactions with these people.

Avoid getting defensive. Stay calm, and be aware that you will never win in an argument with impossible people — they are referred to as "impossible"for a reason. In their mind, you are the problem.. They've already decided that your opinion doesn't matter and your defence is a decorative evidence.

Adjust your strategy., so treat it like a game. Learn the impossible person's strategy, and develop counter strategies ahead of time. Eventually you'll find what works and what doesn't, plus you'll probably feel better as you realize you' re three steps ahead, outwitting (智胜) them at every turn. Just remember your ultimate goal is to help free yourself mentally, not become the person's master.

. Impossible people offer valuable life experiences. After dealing with them, you will be able to get along with most other people more easily. Try to keep perspective, and realize that what may seem crazy to you may be another person's only way of coping. Try to view these interactions as a way to build strengths such as flexibility, grace, and tolerance.

Watch out for picking up impossible people's characteristics. You tend to pick up on the behavior of those around you. For this reason, you could find yourself adopting the very characteristics that you dislike by accident. You may engage in the same illogical behavior in response to the impossible person..
 

A. Accept the situation

B. Consider what you can learn

C. Catch yourself when you start to do this

D. Sometimes you can't leave the situation

E. So nothing you say can convince them to see your side of the story

F. Pointing out that these people are difficult and demanding won't help

G. An impossible person is convinced that they have already made a mistake

Images from Razavi's practice could help train the AI on blips it missed, so it improves over time. Razavi's colleagues are still collecting data, but they are excited about it.

Chest X-rays aren't the only type of medical imaging getting AI assistance. Doctors are using the technology to analyse ultrasound videos of babies' hearts and more. AI technology in medicine is growing rapidly. "Imaging is leading the way," said Stanford University radiologist Curtis Langlotz.

It's not unusual for Langlotz to arrive at the hospital early on Saturday mornings to find at least 150 patient images waiting for him to review. He'll examine chest X-rays carefully, looking for abnormal nodules (结节) in the lungs. It's a tiring job that takes training and attention to detail, but even experts can make mistakes. "We need help," Langlotz said.

What can be extremely challenging for humans may be a ripe opportunity for AI. With massive quantities of high-quality digital images, scientists can train AI computer models to seek out specific features in a person's scan, like signs of lung disease on an X-ray. Such models may help improve radiologists' accuracy and efficiency, so doctors can prioritize cases based on which ones may need immediate attention.

The model isn't ready for widespread roll-out. The researchers first need to train it on more data. "With too many variables that might confuse it, the researchers estimate that more training plus trials to confirm the model works could take five years," says Julia Vogt, a computer scientist at ETH Zurich.

"Using AI tools thoughtfully could ultimately make health care more efficient," Vogt says. "AI is not magic or perfect, but it has the potential to solve some problems. By easing workloads, for example, AI could give doctors more time with their patients. That would be a huge achievement."
