A train enthusiast from China has set a new Guinness World Record for the "Greatest distance travelled by train in 24 hours," (cover) an impressive 5, 887.76 kilometers within a single day, according to the official WeChat account of Guinness World Records.

The traveler, Wang Dong, journeyed Shenzhen in South China's Guangdong Province to Beijing, then to Shanghai, Guiyang, and (eventual) to Yibin in Southwest China's Sichuan Province, in February, 2025, arriving with only 40 seconds to spare before the 24-hour deadline.

The most intense moment came, Wang had only 31 minutes to transfer (换乘) from Beijing West Station to Beijing South Station by subway. With his incoming train (delay) by three minutes, he relied on experience and ran through the station — managing (catch) his next train in just 22 minutes.

The real (excite) came near the end of the journey. "My final train, D5122 from Guiyang to Yibin, was planned just four minutes before the 24-hour mark," Wang said. "If it had been put off by over three minutes, my attempt would have failed."

Unfortunately, when D5 122 pulled into Yibin, it was indeed late — but only by 2 minutes.

As the doors opened and Wang (step) onto the platform, his watch showed just 40 seconds remaining, which was exciting margin (差距) between success and failure.

At the end of his journey, made Mr Wang think highly of the power of China's high-speed railway system was its rapid development and high efficiency, which made the impossible possible.

The idea of homework goes back a long way. Historians trace it to ancient Rome. Pliny the Younger, a teacher around AD 61-113, encouraged students to practice speaking at home. Homework evolved slowly over the centuries. In the U.S., it grew common in the early 20th century. In 1957, American schools piled on homework to raise academic demands. By the 1980s, it was seen as key to academic success.

For high schoolers, homework links to academic performance. But younger kids seem to gain little from traditional homework. Furthermore, students who are responsible and supported at home are most likely to complete assignments and benefit from them. For students from lower-income families who might lack internet access, homework can actually widen the achievement gap.

Then everything changed. As educators recognized the limitations of passive, one-size-fits-all tasks in encouraging genuine understanding and student engagement, traditional worksheets and reading logs gave way to project-based assignments or online lessons, clouding the line between homework and classwork. However, just assigning tasks wasn't enough.

So, what now? Keep, change, or get rid of it? It all comes down to how it's used. When it's just something to keep kids busy, it doesn't do much. But when thoughtful, clear, and actually fitting what a student needs, it has its place. In a world where information is instant, the purpose of homework needs a fresh look.

A. The concept, however, faded significantly during the Middle Ages.

B. The question of whether homework actually helps students is tricky.

C. The thing is, homework isn't automatically good or bad.

D. Furthermore, access to reliable internet became a critical factor.

E. It took on a more formal role during the Industrial Revolution.

F. Ask students what school's like, and you'll hear about tests, teachers and homework.

G. Without engagement, feedback, and support, homework lost its effectiveness.

The research process involved extracting specific polymers from common brown seaweed and modifying them to create a durable yet flexible material. Laboratory tests confirmed that the new bioplastic possesses strength comparable to traditional plastic packaging. Most significantly, when exposed to soil or seawater, it breaks down into harmless organic matter through natural microbial activity. Field experiments showed complete decomposition within four to eight weeks, leaving no microplastic residues. The production method is also energy-efficient, requiring 30% less energy than conventional plastic manufacturing.

Dr. Emily Chen, the lead researcher, expressed cautious optimism about the potential impact. "This material could revolutionize packaging industries, particularly for food and consumer goods," she stated. However, she acknowledged the challenges ahead, noting that "scaling up production while maintaining cost competitiveness with established plastics remains a significant hurdle." Several major companies have already shown interest in adopting this technology, recognizing both its environmental benefits and growing consumer demand for sustainable products. The team is now focusing on optimizing the material for various commercial applications and conducting further tests to ensure its safety and durability meet industry standards.

Traditional purifiers struggle with two critical flaws: they cannot filter particles smaller than 0.01 micron, such as certain heavy metals, and users often forget to replace filter elements. The QingShui-1 team targeted these gaps with a multi-layer composite filter made of activated carbon and ceramic. Laboratory tests confirm it removes 99.8% of heavy metals and 99.5% of bacteria, trapping particles as small as 0.001 micron.

What sets it apart is smart connectivity. Linked to a WeChat mini-program, the device sends real-time alerts when the filter element nears expiration, and users can order replacements directly through the app. This solves the long-standing problem of delayed maintenance that undermines water safety.

Installation and usability were also prioritized. Its compact size fits under most kitchen sinks, and it connects to standard faucets in 5 minutes — no professional help needed. A month-long trial with 500 families in Guangzhou and Shanghai yielded positive feedback. "I used to stress about my baby's drinking water," said Ms. Chen, a participant. "Now I check quality on my phone anytime — it's such a relief."

Mass production is scheduled for December 2025, with a price 20% lower than imported alternatives. This innovation not only enhances household water safety but also makes advanced treatment technology accessible to ordinary families, reflecting China's practical approach to solving daily life challenges.

Anika's inspiration came from witnessing her grandfather struggle with diabetes-related vision loss, a condition that could have been managed with earlier diagnosis. With limited resources, she spent over a year teaching herself machine learning and collecting thousands of public medical images to train her model. The resulting software can analyze images of a person's retina taken with a smartphone adapter and identify early signs of diseases like diabetic retinopathy with an accuracy exceeding 90%. Its low cost is a key advantage, making it potentially accessible to rural clinics in developing regions.

"My goal is not to replace doctors, but to provide a tool that helps them, especially in areas with few specialists," Anika stated. Her computer science teacher, Mr. Patel, described her as incredibly resourceful, highlighting how she solved complex problems using free online courses and collaborative coding platforms. Anika has already begun working with a non-profit organization to pilot "EyeScan AI" in several community health centers. She believes that technology should bridge healthcare gaps, and she plans to continue her studies in both computer science and public health to further this mission.

The first time we set eyes on "Big Red", father, mother and I were on our way home. As we passed the Eaton's department store's window, we stopped as usual to have a look and do a bit of dreaming.

The beautifully decorated window display held the best toys ever. There were dolls much too pretty to play with. And they all lay beneath a surprisingly fantastic dress. Mother's eyes were glued to its shining red satin (缎子).

"My goodness," she whispered. "Look, at that!" Then, mother looked down at her own coat -she had worn the heavy grey wool coat every winter for as long as I could remember. Mom was forever doing chores-washing laundry, tending the pigs and working in the garden-so she always wore housedresses and an apron (围裙) to protect the front. She did have one or two "special" dresses saved for church on Sundays. Also, she managed to make almost all of our clothes. They weren't fancy, but they were comfortable.

"What a silly dress!" She shook her head. "Who on earth would want such a big dress?" As we continued down the street, mother turned her head for one more look. "My goodness! You'd think they'd display something a person could use!"

Mother's Day was nearing, and the red dress was soon forgotten. Mother, of all people, was not one to spend money on items that were not practical. "There are things we need more than this." She'd always say. Choosing a gift for Mother's Day for her was quite hard. When Dad and I asked, she thought carefully then asked for some tea towels, face cloths or a new basin.

On our last trip to town before Mother's Day, we were driving up Main Street when Mother suddenly shouted in surprise: "Look!" She pointed excitedly as Dad drove past Eaton's. "That big red dress is gone," she said in disbelief. "Who'd be fool enough to buy such a dress?" Mother questioned, shaking her head. I was almost certain that I noticed a trace of longing (一丝渴望) in her voice.

The vibrant Naadam festival, a cornerstone of Mongolian culture in north China's Inner Mongolia Autonomous Region, (continue) to attract large numbers of locals and tourists each summer. Meaning "games" in Mongolian, this nationally (recognize) intangible cultural heritage event celebrates strength, courage, and tradition through its historic "Three Manly Games": Bokh (Mongolian wrestling), horse racing, and archery, with documented roots (date) back 800 years.

The 35th Inner Mongolia Grassland Naadam Festival started on July 19 in Xilin Gol League in heavy rain. the downpour created muddy conditions for some visitors, rainfall is considered auspicious on the grasslands, symbolizing prosperity for livestock and pastures (牧场).

The opening ceremony featured striking procession (队列) of over 1,000 herders and 512 traditionally dressed, bare-chested wrestlers circling an arena. Performances highlighted distinctive Mongolian arts like throat singing and Long Song (蒙古长调). Dynamic moments, such as female riders grabbing hada scarves full speed and archers swiftly releasing arrows, became popular online content.

Despite weather-related delays to some events, people remained (enthusiasm). The festival proved economically significant: by the morning of July 21, the main venue alone (welcome) over 200,000 visits, generating revenue exceeding 60 million yuan ($8.4 million) — a 40% year-on-year increase. Naadam (powerful) represents Mongolian heritage and spirit, drawing widespread (participate) and appreciation.

Size Matters — But Bigger Isn't Always Better

. Do you need ample space for a family of four, or is it just you and a partner hitting the road? Larger campers offer more comfort and storage, but they can be harder to park, especially in tight spots or remote locations. Smaller camper vans, while more fuel-efficient and maneuverable (操纵灵活的), may lack facilities like full kitchens or bathrooms. Consider how much time you'll spend inside versus outdoors — this can help determine the right balance between space and practicality.

Off-Grid (离网) Capabilities

If your idea of adventure involves getting off the beaten path, look for a camper van with off-grid capabilities.. These features allow you to stay longer in remote areas without hooking up to external power or water sources. Additionally, some models come with reinforced suspensions for rough area, making them ideal for national parks or backcountry exploration.

Your budget will play a big role in determining feasibility.. Consider buying used or opting for a basic model to customize later. Ex-rental vehicles may have higher mileage but are typically well-maintained. Don't forget to factor in insurance, maintenance, and storage costs — these can add up quickly. If financing, compare loan terms and interest rates to avoid unexpected expenses.

A. Budget Considerations

B. The first thing to consider is size

C. Make a list of must-haves and nice-to-haves

D. This might include larger water tanks, solar panels, and tires

E. New camper vans can be pricey, especially with high-end features

F. More functions increase vehicle weight, affecting fuel efficiency and handling

G. But by focusing on your specific needs, you can find the one to suit your lifestyle

Led by biologist James Monaghan, a team of researchers genetically engineered axolotls to glow in the dark, enabling precise tracking of their regeneration. Their investigation identified retinoic acid — a vitamin A derivative (衍生物) common in skincare — as the key driver of limb regrowth. This molecule acts as a blueprint, ensuring correct limb regrowth (e.g., a hand instead of an entire arm). Developmental biologist Catherine McCusker highlighted a long-standing puzzle: "How does regenerating tissue know exactly what to rebuild?"

To answer this question, Monaghan's team tested the effects of varying retinoic acid (视黄酸) concentrations on amputated (切断的) axolotl limbs. Experiments revealed distinct retinoic acid gradients along limbs: higher concentrations near shoulders triggered complete limb regeneration, while lower concentrations near hands/feet resulted only in finger or toe regrowth. The enzyme (酶) CYP26B1 regulates this gradient by breaking down excess retinoic acid, controlling its distribution. Moreover, a gene called Shox — targeted by retinoic acid — is essential to this process, according to the study.

Humans share these biological components: retinoic acid pathways and the Shox gene. "We have the machinery — we just need to activate it," Monaghan stated, imagining future medical patches that could reprogram human cells to regenerate limbs rather than form scars.

While clinical applications remain years away, this research provides foundational knowledge. McCusker emphasized: "Investment in basic science is crucial. Understanding axolotls brings us closer to solving human regeneration challenges." The study clarifies nature's repair manual, potentially transforming trauma treatment.

I intentionally walked in front of an oncoming car — to avoid a pigeon. As the car came to a sudden stop just a few feet away, I panicked, realizing I almost got killed. "What's wrong with you?" the driver yelled, cursing angrily. "Do you want to die?"

I knew what was wrong with me. I had a lifelong fear of birds. My mother claimed that, when I was an infant, I started to cry if a bird flew past my baby carriage. During my childhood, I dashed away from bird cages in pet stores. The sound of birds singing outside left me shaking. Well-meaning friends of my parents tried to break my extreme fear by taking their talkative bird from its cage and letting it fly around me. They asked me to allow the bird to stay on my arm for one second, two seconds and more to get rid of my fear. However, I'd run away from the room screaming, convinced that their noisy parrot would peck out my eyes.

When I watched Alfred Hitchcock's The Birds on television, I knew my fear was reasonable. In the plot, ordinary birds tore open roofs and violently attacked people. I always knew that birds would rise up against humanity someday.

One day, while I and my daughter were in the park, she noticed a small sparrow struggling to fly. Instead of running away, she gently picked it up and held it gently in her hands. She spoke softly to it, and after a few minutes, the bird regained its strength and flew away. She looked at me with a smile and said, "Mom, what a lovely bird!"

Somehow, my rooted fear of birds seemed to lessen a little at that moment. Her interaction with the bird gave me a sense of hope and confidence. However, I was still attached to the fantasy that birds would attack me, bite my face, claw at my eyes, and possibly kill me. I wasn't sure if I could change.

Summer, for many of us, means more time outdoors, school vacations and a more relaxed atmosphere. But the season also (bring) extreme heat and seasonal depression, which can be hard on our brains. Days and years of exposure persistent heat can hurt the heart and kidneys, disrupt sleep and challenge our mental health.

To protect (you), you should give time to adapt to the heat and stay hydrated (含水份的). Don't exercise outdoors alone, and learn to recognize the (sign) of heatstroke. (get) out of the heat, even for a few hours, is protective during heat waves.

Air conditioning and electric fans can help, but may not always be available, such as during a power failure. Putting the skin in water may be effective alternative to going to designated cooling centers in your community.

If you feel (well), weak, confused, those are all "red flags". Begin cooling (immediate) even before a full diagnosis if heatstroke is suspected, experts say. You can apply ice (wrap) in towels to the neck. You can also use the method of cold water immersion (浸泡), is the first-line treatment for heatstroke.

Several men tried to force the boys' door but it didn't work. Then they raced downstairs. Soon, a group of people gathered below. Despite3 to each other, they united for one purpose. "Jump!" they shouted,4 the boy to trust them. "It's better to break a bone than to5," one voice yelled. The boy6, staring at the ground. Behind him, the balcony was burning so7. Then, he climbed onto the windowsill, his legs trembling.

"He looked down, checking we were ready," one rescuer later8. As the boy crashed through the air, the group quickly formed a9 made by people. Some braced their chests and others locked arms, while the rest supported from behind. The impact from dropping made them collapse to the ground, but the boy was10.

"He landed directly in our arms," said one, his voice shaking. "A miracle — he's safe," another person wept in11. These individuals from various backgrounds had been going about12 lives — shopping, meeting family, working when screams drew them together. In minutes, human13 overcame fear. They became a human net for a child they'd never met before.

"None of us thought twice," one said. "When you see a child in danger, you14." And during that process, strangers became heroes, and a15 moment became a story of hope.

What is motivation?. Motivation often centers on aligning (结合) individual and team goals with the organization's mission and values. Motivation involves encouraging individuals or a team to willingly pursue a common goal. In order for the employees to be motivated, a leader must combine personal goals with organizational goals.

Motivation isn't something just bound to leaders or a workplace, but it is something that is present in all of us.. There must always be a reason to do something in life. That nudge is called motivation.

. According to my experiences, "Manipulation is influencing others when we want them to do something and only we benefit from their actions".

All of us are vulnerable (脆弱的) at some point in our lives, and manipulators see this as the golden time to strike. If your boss or someone else at your workplace is a manipulator, then know that they will target you when you are at the lowest point in your life..

There are different types of leadership styles.. Successful leaders aim to motivate their team members by fostering a positive work environment. Leaders that manipulate will always avoid responsibility. Maybe they didn't provide the exact work details and that made you fail at a task, or something else.

A. Some manipulate while some motivate

B. Leaders recognize and reward team members

C. Our parents, friends, and everyone motivate us

D. Manipulation is the exact opposite of motivation

E. Motivation originates in the heart of the motivated

F. Motivation comes from the inner self of the leader

G. If you share too much with them, they will use it against you

Microplastics mostly come from larger plastics, which degrade (降解) with use or when they aren't disposed of properly. These microplastics end up in our air, soil, water and food. The wear and tear on our car tires, for example, produces particles that pollute the air and water. Humans breathe in these particles — and harmful chemicals within them.

Microplastics have been found in human stool (粪便) and urine. Some studies have suggested that the plastic not excreted in waste appears to pass out of the gut and into the blood, and from there can migrate to other organs like the liver and brain. Animal studies indicate that microplastics can also affect lung and gut functioning and may increase the risk for lung and colon cancer.

One of the most effective steps might simply be not drinking from plastic water bottles, especially if they've been sitting out in the sun. Another is to avoid heating food in plastic containers. Experts recommended switching to glass or steel containers for food storage. Eating more fresh fruits and vegetables can help, too. Regularly vacuuming your house and using an air purifier can reduce the amount of microplastics.

These measures have limitations, however. Plastic is widespread and often the most affordable option. "It shouldn't all be on the consumer to have to make those choices," said Christy Tyler, a professor of environmental science at the Rochester Institute of Technology.

Experts, including Tyler, said governments would have to regulate and reduce nonessential plastics to stop that accumulation. Some already have. The United States and Europe banned the use of microbeads (微珠) in makeup, for example, and several U.S. states are phasing out Styrofoam in food packaging. And 175 countries have agreed to create a United Nations treaty to end plastic pollution. Compared to 20 years ago, Dr. Thompson said, there's now "a public appetite" for change.

I eat alone at restaurants — and I do it a lot. This usually seems to make people around me uncomfortable. Recently, I went to a restaurant for dinner and mistakenly booked a table for two instead of one. The chef working that night saw me and came to say how sorry she was that I had, in her mind, been abandoned for the evening. Before I could correct her, she gave me an extra dessert for my sadness.

I've never been afraid to eat alone. Women don't need encouragement to live an independent life. It is uncomfortable to be treated like a sad, lost lamb just because someone has not accompanied me outside. It is neither brave nor sad for a woman to dine alone.

In the 19th century, some hotels reserved separate dining rooms called "ladies' ordinaries" for women dining alone. Into the 20th century, women could be refused service at pubs or hotel eating rooms without a male. Change was slow to come. Some restaurants maintained different forms of men-only policies. In 1969, Betty Friedan and some other women stormed the Oak Room in the Plaza Hotel to demand that women be allowed in during the male-only lunch hours. The restaurant soon changed its policy — and the agitation (骚动) inspired a wave of protests at other restaurants across the country. In 1970, a federal suit and a new law required New York City's oldest saloon to abandon its 116-year ban on women.

The social stereotype around women dining alone seems to tell us: men occupy the public and women the private. Dining alone hopefully pushes against that view of the world and expands the social imagination on women's autonomy.

The people who offer free drinks aren't cruel, of course. Quite the opposite: Those are generous and friendly ones. But friendly or not, it's part of wrong understanding. And when I'm eating alone. I don't want to be a symbol. I'm just there to read my book, have a middling steak and drink my free champagne in peace.
