Mrs. Thompson, the 78-year-old widow (遗孀), had been living alone since her husband's4. Mia discovered she hadn't had a proper meal in days. "My hands shake too much to cook," Mrs. Thompson explained. Deeply concerned, Mia decided to5 her daily lunch breaks to prepare soup and sandwiches.

Word spread6 at school. Soon, five classmates7 Mia's "Lunch Brigade". They created a8 system: Some cooked, others delivered meals, and a few even9 grocery shopping for seniors. What began as a small gesture grew into a community-wide movement.

One rainy afternoon, Mia found a note under a food container. "Your kindness gave me hope when I felt10 . Thank you for reminding me I'm not11." Tears filled her eyes as she realized their actions carried more than meals — they delivered12 .

The local newspaper13 their story, inspiring nearby towns to start similar programs. Years later, while14 at a nursing home during college, Mia met a volunteer who said, "I joined because your story touched me. Kindness is like the sun — it lights others without15 itself."

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."

In the Chinese calendar, the Year of the Snake will fall on January 29, 2025, following the Year of the Dragon. Chinese astrology (占星术), a rich and ancient system, consists of 12 zodiac animals, each (symbolize) unique qualities. Each year is also linked one of the five elements — metal, wood, water, fire, and earth — interact in a harmonious dance to promote balance and harmony in the world. It is believed that the personality of individuals born in a specific year (shape) by both the animal and the element associated with that year.

In 2025, we will enter the Year of the Wood Snake, a period also (refer) to as the Green Snake because wood is (traditional) associated with the color green. The snake stands for wisdom and agility (灵敏) in Chinese culture, while wood represents growth, (flexible), and tolerance.

The last Year of the Wood Snake was in 1965, a year of great changes. Key events (include) the Voting Rights Act in the U.S., the first spacewalk by a Soviet cosmonaut, Singapore's independence. However, there were challenges too, such as the Vietnam War and bank runs in Hong Kong.

In 2025, the Chinese New Year is distinguished by the rare occurrence of two "springs" (lichun), a phenomenon believed (bring) more good fortune, making it a lucky year for major decisions like marriage.

That's when I3 a secret: Washington, D. C., the city where I live, is full of hidden fossils (化石). In my busy, overstimulated life, I began to4 fossils. Many of these sites lie within 80 miles south of the capital along the Potomac River, so fossil hunting5 takes me away from the city. It's a pursuit that requires6 and focus. Finding different shapes in the earth feels like piecing together a broken7 in the sediment (沉淀物). Is it a tooth, a bone, or a shell? I'm looking for the8 end pieces. Thankfully, my9 phone signal in these areas helps me disconnect from the distractions of the modern world, allowing me to fully immerse myself in the search for fossils. Unlike the rush of daily life, fossils don't demand my constant10 because they've waited millions of years, and they can wait a little longer.

Once, I brought a bottle-cap-sized trilobite (三叶虫) fossil into the newsroom and kept it within my sight, since it was something I wanted to11 throughout the day. Turning over that piece of rock is a12 to remind me of a time long before humans13 and built cities on these lands.

Thinking about geological time makes me feel small but significant, like the tiny trilobite. As my worried mind14 , I realize that many of the stressful details don't really matter. My perspective shifts. Maybe, in this moment, I don't need to rush or worry about that phone call at all.15 , I can savor the quiet, gentle pace of the world around me, just like the fossils waiting to be discovered.

Many people are skeptical about reducing meat consumption, but there are many benefits of adopting plant-based diet. Besides, it produces significantly fewer greenhouse gases and requires less land and water than animals. This helps keep ecological balance and promotes better life quality.

This kind of diet is not usually preferred by people who enjoy the taste of animal meat. Just like the resistance some people have towards eating insects, the shift to plant-based diet also requires great changes in how people perceive and enjoy food.

The future of our food supply will depend heavily on our willingness to accept more sustainable eating habits. Options like lab-grown meats are promising. Yet will these food choices become common in our supermarkets?

How we choose to eat in the coming years will contribute to ensuring a sustainable future for you and me. Hopefully, we can balance our nutritional needs with the planet's ability to support us, building a harmonious relationship with our environment.

A. Such diet has been tried by many people.

B. It remains to be seen whether we can make it happen.

C. It is more nutritious compared with animal-based food.

D. Much depends on how such restaurants treat customers.

E. However, adapting to plant-based diet can be challenging.

F. Our choices directly impact the ecosystem and social welfare.

G. A practical solution is plant-based diet including fruits, vegetables and nuts.

Research on classroom-based group work reveals a paradox (悖论): while cooperative learning can be highly effective, merely placing children in groups often proves unproductive. The solution lies in teaching children how to cooperate effectively. Teachers play a crucial role in this process through their interaction with students.

To ensure effective group work, teachers must first raise students' awareness of the purpose and value of group activities. More importantly, they need to teach students how to engage in reasoned discussions, known as Exploratory Talk. This involves considering everyone's viewpoints, justifying arguments with reasons, and seeking evidence to support arguments. It also involves expressing critically but constructively, such as other ideas, ideas, contributions, and seeking further explanation.

Successful cooperation requires a reasoned discussion, which can be facilitated by establishing a set of "Ground Rules for Exploratory Talk". These rules guide behaviors such as asking for information, seeking and providing reasons, and evaluating proposals. Ground Rules help children ask questions, contribute, reason, and develop ideas. For instance, children learn to ask "What do you think? Why?" and listen attentively to each other's responses, reaching reasoned conclusions.

Exploratory Talk enhances group activities as a powerful learning tool. Certain activities, like Talking Points, are particularly effective in stimulating such discussions. Talking Points are inspiring statements designed to encourage children to share knowledge and ideas on a specific topic. Research indicates that children's Talking Points about more imaginative and extensive responses to traditional questions. They help children focus on the topic and compare their viewpoints with others. As they discuss children realize that their ideas can develop with new evidence and that alternative or valuable sources are new thinking. With proper guidance, the students will soon begin to see their ideas flowing. And gradually they will learn to participate fully not only in discussions but also in life as well.

I like my close friends a lot, and yet, on an almost daily basis, they shocked me. I have a friend who thinks voting is a waste of time; I have another friend who never takes any arrangement to meet at a given time and place seriously.

It's generally held that friends are people with whom we choose to develop relationships because we find their personalities agreeable, or similar to our own, and yet experience regularly contradicts this. What is a friend, really? All that one can safely say is that a friend is someone one likes and wishes to see again.

The truth is that we don't know our friends. Numerous studies show that we tend to assume our friends agree with us more than they really do. The striking part is that the problem doesn't appear to lessen as a friendship deepens. When the researchers Michael Gill and Bill Swann questioned students sharing rooms, they found that, as time passed,people became even more confident in the accuracy of their judgments about the other, and yet, in reality, the judgments grew no more accurate. Two people might become dear friends, yet remain ignorant about vast areas of each other's inner lives.

This seems strange, until you consider, that many-of the benefits that friendship provides don't necessarily depend on perfect familiarity; they come from something closer to reliability. Friendahip may be less about being drawn to someone's personality than about finding someone willing to keep you company, or lend an ear. A friend provides the "social-identity support" we desire. You needn't be a close match with someone, nor deeply familiar with their mind. And once a friendship has begun, you want to like it, if only to confirm that you made the right decision. We don't want to know everything about our friends. We don't base friendships on what we learn about people; we decide what to learn about people, and what to ignore, based on having decided to be friends.

Perhaps there's something moving about viewing friendship as an agreement to keep each other company, ignore each other's faults and not probe (刨根问底) too deeply in ways that might weaken the friendship. Perhaps a true friend is someone who doesn't ask many awkward questions.
