Focus on the present moment.

Practice mindfulness daily to clear your mind and focus better. It means focusing on what you're doing right now and letting other thoughts come and go. Then, let them go and concentrate on your current activity. Emotions are constantly changing and flowing, so it's okay not to understand why or how you feel a certain way. Just let them come and go naturally.

Take time to write down your tasks for the day for a fresh start. This may seem dull and silly, but it can make the busiest days seem more manageable. Before you start your day, write down everything you want to accomplish, including fun activities and tasks. Making a to-do list will give your day structure and help things seem more manageable.

Take a walk.

Moving your body mindfully can help things seem clearer. When you're mindful, you're fully in the present, letting feelings come and go as you focus. Walking mindfully reduces stress and boosts both mental and physical health. Try a daily walk around the block, on the treadmill (跑步机), or through a local park.

A busy mind is natural, but you can regain control. Mindfulness, planning, and movement are simple yet powerful tools. By focusing on the present, embracing small actions, and treating yourself kindly, you'll build mental clarity.

A. Make a to-do list.

B. Write down your thoughts.

C. First, watch your thoughts without judging them.

D. Anxious thoughts fueled by stress can spoil your day.

E. This simple activity helps you step away from your daily worries.

F. Start with one technique and take the first step toward a calmer mind today.

G. Despite these, achieving mental clarity remains impossible without professional help.

A recent international study led by Dr. Zeus Gracia Tabuenca examined 151 adults divided into three categories: those who learned two languages before age 6, those who acquired a second language after age 12, and those who can only speak one language. Using functional magnetic resonance imaging (fMRI)— a brain-scanning technique that measures activity through blood flow changes — researchers analyzed connectivity between different brain regions while participants were at rest.

The results revealed striking differences. Early bilinguals showed 23% stronger neural connections between the cerebellum(小脑), which coordinates complex movements, and the frontal cortex(前额皮层), responsible for advanced thinking skills. Even late bilinguals demonstrated 9% stronger connections compared to monolingual participants. Furthermore, the study found that each year of delay in learning a second language after age 6 reduced connectivity gains by approximately 1.7%.

"These findings suggest that early language exposure doesn't just teach vocabulary — it upgrades the brain's connectivity," explained Dr. Tabuenca. The enhanced connectivity is linked to better cognitive performance: participants with stronger neural networks solved logic puzzles 18% faster and recalled 25% more words in memory tests.

This research builds upon previous work showing bilingual can help people focus better and lower the risk of memory-loss diseases. However, critics warn not to rely too much on lab findings. "While the data is convincing, real-world educational outcomes depend on multiple factors beyond brain scans," said Dr. Emily White, an education specialist not involved in the study.

The study also revealed an unexpected role of the cerebellum. Traditionally associated with physical coordination, this region now appears crucial for cognitive flexibility. "It's like discovering a new highway between two major cities," Dr. Tabuenca said, "The more lanes you build in childhood, the smoother information travels throughout life."

For instance, Chongqing primary students developed voice-controlled lamps using programming, while Yangzhou High School compared human and machine learning through flower recognition.

AI tools like translation apps and voice pens aid language learning, offering instant feedback. Universities like Peking University employ AI tutoring platforms to personalize learning, while agricultural colleges use smart systems to simulate real-world farming challenges.

Experts highlight AI's role in enabling lifelong learning, critical thinking, and addressing educational inequalities. However, challenges remain, such as redefining teachers' roles. Hong Kong educator Keric Lee observes that AI shifts assessments from memorization to creativity. In one project, older students used AI to illustrate stories written by younger peers, promoting cooperative learning. Teachers now act as guides rather than knowledge authorities, encouraging peer reviews and innovation.

The integration of AI in education is not just about teaching students how to use technology. It's about preparing them for a future where AI is widespread. Schools are now focusing on developing a new generation of critical thinkers who can work alongside AI, rather than being replaced by it. This shift requires a significant change in education, moving from traditional teaching methods to more interactive and engaging learning experiences.

"Educators need to consider how to play new roles in the classroom, empower students and encourage them to review and appreciate each other's work, thus promoting progress. This is the key to learning for the new generation," Lee added.

But last summer, when I came back from college, I was shocked. The once-beautiful river was now full of plastic bags and chemical foam(泡沫). Dead fish floated on the surface, and the smell of rot was everywhere. My dad's stories echoed in my ears like a joke. That night, I couldn't sleep.

By morning, I had a plan. I made posters and got my classmates together — Lily, who loved biology; Tom, the rugby team captain; and even shy Mei from the art club. We met at the riverbank the next Saturday, with gloves and determination. Old Mr. Li, who still fished in the dirty water, laughed and said, "Fools! You can't fix what's already dead."

The work was tough. We had to remove tires, broken TVs, and a rusty bicycle buried in the mud. One rainy afternoon, as I tried to pull a broken fridge out of the mud, my foot slipped on some algae. I fell into the rocks and cut my hand. Lily was shocked, but before she could say anything, old Mr. Li came over with bandages and some ginger tea. "Stubborn kid," he said, but his eyes were kind. "You've made me recall this river was once our life."

By winter, something amazing happened. Kingfishers came back, flying through the air with their bright blue wings. Kids started skipping stones again, and their laughter filled the air. At our last gathering, Tom held up a photo from our first cleanup: a big pile of trash bags. "Look how far we've come," he said. But the real win wasn't just a clean river — it was the village finding its heart again, one bottle at a time.

Taj Mahal, India

The Taj Mahal, a white marble mausoleum (陵墓), is celebrated as the finest example of Indo-Islamic architecture. Built in 1632 by Mughal Emperor Shah Jahan, it honors his beloved wife, Mumtaz Mahal. Its grand design features arches, domes (圆顶), and intricate stone inlay work (镶嵌画).

Angkor Wat, Cambodia

Angkor Wat, part of the ancient Khmer Empire's capital, is the world's largest religious structure. Originally a Hindu temple for Vishnu, this 9th-century temple complex showcases detailed carvings and remains a symbol of Southeast Asia's rich history.

Acropolis of Athens, Greece

The Acropolis of Athens is an enduring symbol of Classical Greece. The crown jewel of this hilltop castle is the Parthenon, a former temple dedicated to the worship of Athena in ancient Greek religion. Built by Ictinus and Callicrates, beginning in 447 BCE, this Doric icon is regarded as the most important surviving ancient Greek monument.

The Great Wall, China

Stretching over 21,000 kilometres, the Great Wall is one of humanity's most ambitious architectural feats. Initially built during the 7th century BCE and expanded by later dynasties, it served as a military defence system against invasions. The best-preserved sections near Beijing, constructed with bricks and stone, display watchtowers and strategic passes. Despite erosion and tourism pressures, it remains a proud symbol of Chinese civilization.

It was almost New Year's Eve, and as I made my way home from work, I decided to stop at the neighborhood coffee shop in our town—a town that had previously been busy and wealthy but was now poor and deserted. After parking in a parking lot that was close to the coffee shop, I headed toward the shop door when I spotted trouble.

What lit a warning light in my mind was a group of teenagers—three boys and a girl, each of whom stood on a skateboard. I wasn't alarmed by the way they were dressed, which showed they seemed to be a group of bad teenagers. Rather, it was the extremely late hour and the fact that they wandered on the sidewalk in a half circle around an elderly man sitting in a chair that raised a red flag in my mind. Wearing only a very worn-out shirt and without shoes on his feet, the old man looked positively cold and probably homeless.

He was in trouble with a capital T. Against my better judgment, I went inside the warm store and ordered nice bread and a cup of coffee while keeping a worried eye on the group outside. Thoughts raced through my mind, and I was wondering what the intentions of these teenagers were. "What do the teenagers want on earth? Do they intend to play a bad trick on the old man, make fun of him, or…?" I wondered, anxious. "Whatever it is, they seem to plan to do something bad to him. Oh, these kids seem to be mean," I thought and felt upset.

But nothing seemed to be happening. Slightly relieved, I began to enjoy my food. However, minutes after I finished my food and headed toward my car, something indeed was "going down". I heard one boy say, "Stand up and walk." "Oh, no," I thought. "The old man is now in real trouble."

On December 4, 2024, the UNESCO included Spring Festival, social practices of the Chinese people in(celebrate) of the traditional new year, on the Representative List of the Intangible Cultural Heritage of Humanity during the 19th session of the Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage. China now has 44 cultural items(recognize) by UNESCO as Intangible Cultural Heritage of Humanity.

According to UNESCO's documentation, the traditional knowledge and customs associated with the Spring Festival(pass) down informally within families and communities, as well as formally through the education system. Craftsmanship and artistic skills related to the festival are spread,(promote) family values, social cohesion(凝聚力), and peace, while providing sense of cultural identity.

The committee also emphasized that the festival represents the harmony between humans and nature and contributes sustainable development in areas such as food security and education. It also plays a key role in raising environmental awareness.

China's vice minister of Culture and Tourism, Rao Quan, led the Chinese delegation, expressed gratitude for the recognition. He(stress) that the Spring Festival is China's most important traditional holiday, symbolizing the Chinese people's hopes for a better life, strong ties to family and country, and the values of harmony between humans and nature.

Rao further explained that the festival, passed down through(generation), has provided lasting(spirit) social harmony, driving economic development, protecting the environment, and encouraging global cultural exchange.

The 35-year-old1 4,740 kilometers in 40 days and 19 hours, battling constantly high winds, big waves and lack of2 to record the fastest female solo row across the Atlantic Ocean. "It was much3 than I expected," she told CNN Sport, "I got probably the strongest wind and the challenges you need to keep going through were4."

Evans had spent four years preparing for this5 of a lifetime but still hadn't been ready for the6 of an ocean crossing. Even before setting off, the trip was7 by issues caused by the COVID-19 pandemic which forced the challenge to be8 by a year. Once the challenge was9, high winds made rowing and sleeping extremely difficult, causing Evans to float off10 at times.

At one point a wave locked the11 door from the inside, leaving her12 outside of her cabin for 3 hours. Despite these occasional challenges, Evans managed to13 in extreme conditions.

"It's a very unique sport14 you can't get off when you're there and you have to deal with it. So it was so, so intense," said Evans, who was15 to cross the Atlantic after climbing Mont Blanc in 2017.

Driven by the desire to share "brave explorer" moments online or a "come all the way up here" mindset, many beginners hurry to seek outdoor adventure without proper preparations. In reality, outdoor activities can be dangerous without enough skills and risk awareness. Beginners who ignore potential dangers may face hypothermia (失温) when hiking to high altitudes, get lost in forests, or be caught in thunderstorms.

So, how can we make outdoor sports safer? Before heading out, research the environment, climate and seasonal conditions to choose a safe route and avoid risky or hard-to-access spots. Knowıng the trail's altitude (海拔) , difficulty level, supply points and emergency stations is crucial, and planning alternative escape routes can be life-saving. Layered clothing is essential to adapt to changing weather conditions. Follow the principle of "remove layers when warm, add layers when cold and change clothes when wet".

However, with systematic preparations, we can. significantly reduce the dangers. Always remember to tell friends or family about your route and estimated return time. so they can assist if needed. With proper preparations and safety measures, these adventures can be both exciting and rewarding.

A. Having the right clothing choices is equally important.

B. On the whole, outdoor sports indeed involve challenges.

C. A well-designed plan and detailed preparation come first.

D. All in all, outdoor sports can bring great fun and/ knowledge.

E. They often lack the necessary equipment to ensure their safety.

F. However, the rise in accidents has cast a shadow on this passion.

G. These accidents highlight that outdoor sports are far more than a simple trip.

Intermittent fasting is a time-restricted diet, where the day's calorie intake is consumed over an 8-12 hour period, with fasting for the remaining hours. Research tracking participants on such diets for three months to a year has shown benefits like weight loss, improved heart health, and better control of blood sugar. These reported benefits have made intermittent fasting a global trend.

However, not all outcomes of intermittent fasting are positive. A study published on December 13 in Cell is among the first to link intermittent fasting with hair loss. The study found that intermittent fasting could block hair follicle (毛囊) regrowth by causing programmed cell death in active hair follicle stem cells (HFSCs). Mice subjected to intermittent fasting showed slower hair regrowth compared to those with regular food access. Though similar results were found in humans in a small clinical trial, the researchers warned that the effects might be less serious in humans due to their slower body processes and different hair growth patterns.

The researchers discovered that intermittent fasting slows hair growth because hair follicle stem cells (HFSCs) struggle to handle oxidative stress (氧化应激) when the body switches from burning sugar to fat for energy. Normally, HFSCs switches between activity and rest, and hair regrowth depends on these cells becoming active. In the study, mice with regular food access had active HFSCs after being shaved, and their hair regrew normally. However, the fasting mice experienced programmed cell death in their active HFSCs, preventing hair regrowth.

Although these findings are significant, they are based on initial studies. Larger trials are needed to better understand how intermittent fasting affects hair growth, as individual responses may vary.

Running Tide was founded by Marty Odlin, an engineer and fourth-generation commercial fisherman. The Gulf of Maine is warming faster than nearly every other oceanic region, and Odlin has seen the changes firsthand. About 15 years ago, Odlin heard a talk from Klaus Lackner — the physicist who popularized the idea of removing carbon from the atmosphere. It clicked. "It was like, oh, this is right because there's no way we're going to get off fossil fuels in the next 50 years," he recalls thinking. "We're going to have to pull it down."

Using seaweed to draw down carbon would be an elegant solution — if it works. Seaweed forests collectively cover an estimated two million square kilometers and absorb as much carbon as the Amazon rainforest. But much of that storage is short-lived. When the seaweed is harvested, eaten by animals, or washes ashore, its stored carbon is released back into the atmosphere. Running Tide's model, in theory at least, would take that stored carbon and sink it to the ocean floor where it would remain for centuries, breaking down slowly.

Some scientists are careful about rushing ahead before fundamental scientific, environmental, and regulatory questions are answered. "Climate change is worsening, and people are panicking," says Kristen Davis, a professor of University of California Irvine, "but the science is not there yet to actually confirm that it's a good idea."

After graduating from Virginia Tech with a degree in engineering in 1956, Walsh was hired by Chrysler in Detroit. "That was the best decision I ever made, because if I'd gone to GM, I could have been lost in a big hurry," Walsh said. The engineer proved his ability while making $485 a month. "I was the youngest chief engineer at Chrysler at that time," Walsh recalled.

Walsh was asked by the manager in 1976 to design a vehicle unlike any other. Walsh's team didn't waste time. "We designed a prototype (原型) by cutting down the big vans," Walsh explained. But the plans Walsh led would sit on a shelf collecting dust. "We kept proving that it was workable through the prototypes," Walsh said. Then eight years later, Chrysler's new CEO Lee Iacocca greenlighted the project. "He thought it was a product that needed to be on the market," Walsh said. "It was decided to produce it in 1984." With its extra space for storing goods and roominess for passengers, the Chrysler minivan was an instant hit. "It became the cash cow of Chrysler Corporation," Walsh said.

After 32 years in Chrysler, Walsh retired in 1988 just four years after the first minivan was produced. "The world's best minivans and that is true," Walsh said. "It was a landmark vehicle."2024 marks the 40th anniversary of the minivan, proving good ideas are highly productive. The 93-year-old doesn't take credit for the minivan. To this day Walsh sings high praise for his talented team.

Admirably, the retired engineer helped introduce a new way of driving. "I enjoyed every minute of those jobs. That is all I have got to say," Walsh said. "I enjoyed every minute of my career. I am very fortunate to be there at the beginning."

Symbols of Animals in Chinese and Western Cultures

In Chinese and Western cultures, animals (acquire) different meanings over time. There are some elements represent one thing to one culture, and something else entirely to another.

The word "bat" in Chinese ("fu") has the same (pronounce) as the Chinese character meaning "luck, happiness and fortune". Therefore, images of bats are often symbols of good luck in China. They are also appreciated their ability to catch insects. , in Western cultures, bats are often associated with darkness.

Due to their unpleasant appearance and call, owls (猫头鹰) were for long considered symbols of bad luck in China. In consequence, owls were used in poetry( represent) evil. A poem in the Classic of Poetry, for example, was written in the tone of a (frighten) bird being bullied by an owl.

Owl. owl, as you have already taken my child, don't destroy my nest.

Yet in Western cultures, the owl is often regarded as symbol of wisdom. In the popular Harry Potter series, the owl is an (extreme) wise and helpful bird.

These differences mirror each culture's distinct background. By exploring these, a deeper understanding of the rich cultures around the world can (unlock).

In a video shared on TikTok, the girl was2 a difficult cheering stunt (特技) during an event organized at Chandler's Basha High School. She was doing flips (空翻) perfectly, getting3 into the air, and coming down safely into the hands of the supporters. But then, a flip in the air4 a problem. She couldn't land5 and was close to falling down. At that moment, her coach and another man stepped in to help.

This left her6. Thinking she lost heart, her coach said gently, "Honey, it's just a small7." But the girl said, "I won't give up though I'm8." The coach replied firmly, "Quite right, honey! You're so9. One failure doesn't mean anything. Let's give it one more10." The crowd in the sports complex, including seniors and school staff present, were11 for the little girl, too.

To everyone's amazement, the little girl12 it this time. All the audience stood up and clapped their hands for her.

This13 episode shows that, like many successful individuals, the girl was able to overcome difficulties with the right attitude and the14 of those around her. It's a powerful reminder that perseverance and encouragement can lead to remarkable15.

When preparing for exams, study groups allow students to share knowledge. For example, one might explain math concepts clearly, while another is strong in analyzing literature. Together, they fill gaps in understanding. A classmate's different viewpoint can turn a confusing problem into a solvable one, puzzle pieces fitting together to reveal a complete picture.

Cooperation also builds social skills. Imagine planning a class event: some prefer creative ideas, others focus on practical details. Through discussion, students learn to balance innovation and realism-a skill vital for adult life. Even disagreements, if handled calmly, become lessons in understanding others' feelings.

Working together helps overcome challenges. During tough times, like preparing for important exams, classmates can support each other emotionally. A shared laugh during a break or encouraging word before a test reduces stress. Research shows students in supportive teams perform better.

However, teamwork requires effort. Avoid relying too much on others or dominating discussions. A good team member contributes actively but also steps back when needed. Think of teamwork as a dance: everyone has a role, and harmony comes from cooperation, not chaos. Regular communication, like weekly check-ins, ensures everyone stays aligned (一致的) while respecting individual strengths.

So, cooperation is a bridge connecting individual talent to collective success. It prepares students not only for exams but also for future careers and relationships.

A. Teamwork makes learning more effective.

B. This simple truth applies to teamwork too.

C. Working on a team, you have the entire group's support.

D. They always stay motivated longer than those working alone.

E. Team members are under heavy pressure to make a decision.

F. Group projects teach us to listen, negotiate and respect differences.

G. For instance, let a teammate lead if he or she understands the topic better.

In daily life, we constantly process visual and auditory (听觉的) information to explore the world. For example, when watching a movie, the brain integrates images and sounds to create a unified experience. However, during movement-such as walking down a busy street-the brain may prioritize visual input over sound to avoid obstacles.

Until now, the neural mechanisms (神经机制) behind this sensory prioritization remained unclear. Understanding this process is particularly important for individuals with sensory processing disorders. such as autism or schizophrenia, where the brain. may grapple with integrating sensory information effectively. By uncovering how the brain naturally shifts between sensory inputs, researchers hope to pave the way for better treatment for these conditions.

To investigate this phenomenon, the research. team conducted behavioral experiments on mice, monitoring real-time brain activity using miniature microscopes and optogenetics, a technique that uses light to control neurons. The mice were trained to respond to both visual and auditory cues while either stationary or running on a treadmill.

The results revealed a striking shift in sensory reliance: When stationary, the ice relied more on auditory cues to make decisions. When moving, their brains prioritized visual input. This suggests that the brain dynamically adjusts sensory weighting based on behavioral context. Sound may be more useful for detecting nearby events when still, whereas vision becomes critical during movement for spatial navigation and stability.

This discovery could have important implications for understanding and treating sensory processing disorders, where the brain may struggle to properly prioritize sensory inputs. Dr. Lee explained, "Our findings demonstrate how the brain flexibly shifts between vision and hearing depending on behavior. Understanding this natural adaptability could lead to improved treatments for those with sensory integration difficulties."

The Hidden Life of Trees argued that trees are social. It shows that they can be our saviors. But it's terribly hard to let ourselves be saved. We think we can be the authors of our salvation (拯救). Of course, there are things we could and should be doing, but in terms of forestry practice, often what's billed as part of the solution is part of the problem.

Anyone who has planted a tree in their garden knows that it has a far-reaching effect — it makes your garden cooler in summer and warmer in winter. Forests cool by transpiring (蒸发). If there's no water, there's no cooling. Drought can kill trees fast, but trees have many ways of dealing with it, and Wohlleben sets them out. As a species, we have survived many climatic changes by changing our behavior — and that's how trees survive, too. Trees learn from their past harms and produce younger ones programmed with those lessons. They regulate their growth by changing the rate at which they drip (点滴)-feed them with sugar solution through root networks.

Deciduous (落叶的) forests in particular remove greenhouse gases effectively as long as they live. Cut them down and burn them and you're releasing carbon dioxide not just from the wood, but also from the forest floor. Deciduous trees are not "harvest-ready" at 200 years: they are teenagers. We must interrogate comforting expressions such as "renewable energy", and learn the real cost of our toilet paper.

If we don't learn to do nothing about trees, they will eventually be alone anyway—but without us. Wohlleben brilliantly and readably shows us how urgent and how hard it is to do nothing.
