The community library was Megan's peaceful kingdom, a place of quiet whispers and turning pages. Every summer vacation, she worked as a student volunteer, feeling responsible for protecting this quiet space.

Lately, a boy named Liam had become her challenge. Liam wasn't rude — he just couldn't sit still. Like clockwork, he would get up to "stretch his legs, "pacing between the bookshelves. Sometimes he'd accidentally knock over a chair. Once, absorbed in a picture book, he let out a loud"Whoa!"when he saw a giant dinosaur filled the page. In the silence, each sound drew looks from other readers.

Yesterday, when Megan walked over and reminded him gently again, Liam's face turned red. "I'm really sorry, "he whispered sincerely. "I don't mean to. I just. I really like being here. "She believed him. She had noticed that Liam was a curious explorer of books. He would pull out a book on dinosaurs, reading with intense focus for a few minutes, then move on to another about volcanoes or space rockets. He just loved the library.

Megan went back to her office. A note on the head librarian's desk caught her eye. It read, "More Lively Reading Activities? Book sharing? Acting?" Seeing this, Megan suddenly remembered the librarian had mentioned she could feel free to use the garden at the back of the library. It was a place where some unused items were stored — some old chairs, folding tables, all piled up gathering dust under a large tree. At the time, Megan hadn't thought much about it. But now, the thoughts of directing Liam's energy and making use of the garden connected in her mind. Perhaps the solution wasn't to quiet Liam down, but to give his energy and love for books a positive stage, right here in their own library.

An idea for a "Garden Reading Corner"project, aimed at young readers, began to take shape. The next morning, she found Liam among the bookshelves. "Want to do something really cool?"she said, her voice low but excited. Liam did not answer at once, but the eager light in his eyes said everything.

When I first opened Where the Deer Hide in the Woods, I felt as if I were stepping into a world the author's words flow like gentle music. The Tang poems, (translate) with the master touch of Xu Yuanchong, speak softly in two voices — one Chinese, one English — each echoing (回响) with calm, beauty, and quiet (deep).

The book (divide) into six chapters, each unfolding a distinct landscape of emotion— sorrow, peace, love, longing, solitude, and reflection. I was (genuine) moved when I read "The monkeys on both banks are still calling; my light boat has sailed past a thousand hills." I fully (sense) Li Bai's liberated soul — his joy at being pardoned by the emperor — flowing through the lines.

Each page of the book is enriched with thoughtful notes, vivid background stories, and traditional Chinese brush-style (illustration). Xu's artful work transforms the rhythm (节奏) of Chinese poems English music, a recreation that honors both the original and its new form.

(read) this book feels like a journey through hearts and landscapes. For anyone who treasures poetry, painting, or the meeting of two cultures in perfect harmony, Where the Deer Hide in the Woods is must-read that beautifully serves as the bridge.

That gorgeous notebook sat2 for months. When I finally opened it, I hesitated. The pages felt too delicate and too3 to waste on my messy handwriting and ideas. So I4 it. Instead, I grabbed an old, ugly composition notebook with a5 cover and dog-eared corners. I started to6 it with everything: morning pages, random thoughts and reminders. This is surprisingly7. I actually wrote. Every day. Without exception.

The psychology is real. When we8 something too much, we place limits around it, feeling it is "too good". But the ugly notebook carries no such9 . It has been used. It tells me, "This is a10 for thinking and living, not a museum piece."

Here's the thing:11 notebooks are idea incubators (孵化器) . With the pressure off, you experiment more. You try things that might12. And in that freedom, bad ideas I was13 embarrassed about gradually evolved into work I'm proud of. And that's where the real work of creation happens.

The best notebook is never the most beautiful one. It's the one you'll actually14. Because the magic happens in the15, not in perfect pages.

Your ugly notebook is waiting.

There is much to appreciate in this form of travel. There is no need to consider weather conditions, health issues or financial pressure. You may enter distant places at any moment and leave just as freely. For those restricted by schedule, health, or income, VR quietly removes barriers that traditional travel often sets in place.

Travelers wander through unfamiliar streets, sample local dishes, and engage face-to-face with people shaped by different traditions. Such encounters awaken the senses and create lasting memories. More importantly, they change how places feel to us, not just how we understand them.

This distinction is clear, because learning about a destination is not the same as being there. Virtual travel offers designed scenes and programmed sensations, but it remains carefully controlled. Real travel, by contrast, is shaped by unpredictability. In those unplanned moments, understanding becomes lived rather than recorded.

Virtual reality will undoubtedly continue to evolve, enriching how we preview journeys and imagine distant worlds. Still, it cannot replace actual presence. Travel is not simply about seeing farther; it is also about feeling where you stand.

A. I am not moving, yet I am traveling.

B. Yet real travel leaves a deeper mark.

C. My feet ache as my journey stretches across the day.

D. Virtual journeys are convenient, time-saving, and widely accessible.

E. Some knowledge, it seems, only arrives when your feet are on the ground.

F. It demands choices, adaptation, and constant awareness of the unexpected.

G. But the convenience may gradually weaken our desire to explore the real world.

Conventional hydropower (水力发电) relies on large water flows, which only work in places like rivers. For smaller, slower flows, researchers have explored charge separation. They use a tube to let water flow through it continuously. Charges gather on the surface that the water touches. In this way, researchers can collect charges, but it is far from effective.

To solve this problem, the NUS team built a special device. At both ends of the device — the top of the newly-designed tube (about 2 millimeters in width), and the water-collecting cup at the bottom — electrical wires were placed to harvest charges. First, water is released from a metal needle, forming rain-like droplets. When these droplets enter the tube, their impacts create "plug flow," in which the water forms mini columns separated by air gaps. This flow is crucial because it allows more surface contact and more time for charges to build up, generating up to 100, 000 times more charge separation than continuous flow. As charged droplets exit the tube and fall into the cup, charges build up in the water, creating an electric current. In tests, four tubes produced enough electricity to power 12 LED lights continuously for 20 seconds.

According to the study's lead author, this model shows how rain can be used to generate clean electricity effectively and sustainably, especially in rainy places such as Singapore. Its potential is enormous, as it offers an alternative energy source even in cities. Imagine a rain collection device on your roof, producing small amounts of electricity whenever it rains — a small step for a raindrop, but a giant leap for sustainable energy technology.

Male chingolos learn their unique, two-second melody from adult males. "It is a distinctive song — like a fingerprint, but learned," says one of the researchers. "It serves to attract females and protect territory. It is the bird's way of saying, "This is me, and here I am." However, urbanization and habitat loss have broken this learning chain, causing local song "dialects" to disappear.

Driven by this problem, researchers took on a pioneering task: bringing back a song that had disappeared from the wild — known only from a musical record made in the 1960s — to a population of chingolos.

Using physics-based modeling of the bird's vocal tract (声道) , the team first created an accurate artificial version of the lost song. They then engineered this model into a physical device designed to broadcast the forgotten melody — a "robotic tutor." This artificial song was introduced to the chingolos in the park during their critical learning period from October to February. The sessions took place during peak singing hours and were limited to a maximum of eight hours. There were random pauses (停顿) in between so that the birds interpreted the playback from the three devices placed in the area as a real exchange, as if these devices were responding to each other. This stimulated the birds' vocal responses.

The results were impressive. Young chingolos learned and adopted the song, though they added their own population's "accent" to the final trill (颤音) , which showed that their singing is shaped by learned behaviors and inborn characteristics.

"This is about preserving not just genetic, but cultural biodiversity," says another researcher. The team is now developing AI systems to automatically identify individual bird songs and planning to study cultural spread in bird populations to ensure that bird culture is not lost again.

Two friends joined me on a four-day wilderness getaway, and since we were all in our seventies, we decided we'd better go while we still could. Our adventure began with a scary drive up a winding mountain road.

On one hike, I found myself hanging onto a wire on a bridge made of two partly rotten (腐烂的) logs, suspended high above rushing rapids. I would never have attempted it without our guide ahead, mouthing encouraging words. Fixing my eyes on her boots, I inched along the shaky logs. Somehow, I made it across, flooded with a rush of intense excitement and huge relief.

Later, after spotting bear tracks, we were told to make loud noises, which soon became a game once the tension faded.

Until suddenly, time stood still.

We had just crossed a stream when the guide whispered, "There's a bear." I looked up in disbelief and saw not one, but two, about ten meters above us— the brown mother in front, her cub behind.

Though scared speechless, I couldn't help noticing how beautiful they looked in their natural setting. I wondered if it would be my last memory. As they started towards us, we recovered enough to shout and wave our hiking poles. Taken aback, they stopped, and then slowly turned away. Another fear was overcome!

On our final morning, after a quiet, thoughtful walk through the forest, we were asked to bring back a "meaningful" stick, rock, and leaf to share what would "stick" with us, what "rocked," and what we would "leaf" behind. The bond of friendship would stick with me. Women supporting one another truly rocked. And I hoped to leave some fears behind.

Our guide ended by expressing her admiration, praising not only our fitness but also our positive attitude, and saying she hoped to be like us in another thirty or forty years. Those unexpected words warmed my heart and eased my fear of being "over the hill." Being valued for what we had accomplished felt like winning an Olympic medal — even if just for participation.

In a little town, there lived a boy named Leo. Leo was a dreamer with a passion for art. He spent most of his days painting the landscapes around him, capturing the beauty of nature in his drawings. However, Leo was shy and often hesitated to share his work with others. He feared criticism and doubted his talent.

One day, the town announced an art competition, inviting artists of all ages to submit their work. The winner would have their artwork displayed in the town hall and receive a scholarship for art classes. The announcement ignited (点燃) Leo's interest. This could be his chance to show his art to the world!

Despite Leo's excitement, his fear returned. "What if I'm not good enough?" he thought. For days, he struggled with his doubts, but deep down, he knew he had to try. Encouraged by his mother, who always believed in his talent, he decided to enter the competition.

Leo spent every free moment working on his piece. He chose to paint the impressive sunset over the hills, the colors reflecting the beauty he admired in nature. As he painted, he poured his heart into the canvas (画布), feeling a sense of freedom and joy. However, as the deadline approached, his insecurities returned. "What if people laugh at my work?" he thought carefully.

On the day of submission, Leo hesitated at the door of the gallery, holding his painting tightly. He took a deep breath and reminded himself of his mother's words: "Art is about expressing yourself, not about pleasing others." Gathering his courage, he stepped inside and handed over his painting.

The following week, the town gathered for the competition's unveiling (揭幕). Leo felt a mix of excitement and fear as he watched other artists present their work. The gallery was crowded with people, and he couldn't help but admire the creativity around him.

In a factory workshop in Huangchuan County, central China's Henan Province, skillful workers stretch pieces of dough (面团) very carefully. They press and turn the dough into thin strips, and then use wooden sticks to pull them apart gently. These strips (hang) to dry, and finally they become the famous hollow tribute noodles (空心贡面) of the area.

Liu Laiwang, representative inheritor of the noodles and boss of a local food company, says, "Making these noodles (be) my work since my childhood. They're a special cultural treasure of Henan, carrying the (wise) of many past generations. We must keep this skill alive and pass it on."

(date) back to the Tang Dynasty (618-907), the noodle earned its name when it was presented the emperor as a form of tribute. The noodles are made from high-quality wheat flour, sesame oil and salt, and their production involves more than ten steps. The noodles are very thin, with a hole in the middle. When (cook), they stay firm and don't get soft or (stick).

In recent years, Huangchuan has actively expanded its noodle industry, aiming to achieve both social and economic benefits. Liu's company alone operates a 5,200-square-meter standardized facility with annual production capacity of 3,000 tons. It has helped over 1,000 local families get out of poverty given jobs to nearly 2,000 workers.

China has many such special cultural treasures, more than 40 of have been put on UNESCO's important list, more than any other country in the world.

According to the International Energy Agency, rising overall demand for electricity is outstripping (超过) the world's efforts to improve efficiency and boost renewables. The fact is, economic development will inevitably require greater2 of electricity. It is increasingly clear that nuclear power plants must play an important role in this equation (制衡关系).

Nuclear power is, in many ways, the most promising source of zero-carbon electricity. Unlike solar, wind and water power, electricity from nuclear plants is3. Generators keep running when the sun is not shining, the wind is not blowing and water levels are low. Nevertheless, the industry has an uncertain and dangerous4. Take the United States as an example. There are fewer commercial reactors (商用核反应堆) in5 today in the country than there were a generation ago. This year could see three commercial reactors6. There are plans to shut down about 20 more over the coming years.

The problem is a misunderstanding of7. Humans are constantly exposed to radiation — from the sun, from the universe, from the very ground we walk on. The alarming near-meltdown at Pennsylvania's Three Mile Island plant in 19798 exposed neighbors to about one-sixth the radiation dose they would receive from having a single X-ray.

Microsoft co-founder Bill Gates is one of a growing number of9 who believe that cheaper, smaller reactors must play a significant part in the post-carbon energy mix. His company Terra Power has announced plans to build a next-generation nuclear reactor at the site of a former coal-fired power plant in Wyoming. The goal is to prove that nuclear power can be10 to the grid (输电网) at a competitive price and on a reasonable timeline.

I'm an optimistic supporter of renewable energy sources. I'm also a (n)11 student of the various impediments (阻碍) to the growth of these sources. I agree with Gates that the surest path to net-zero carbon emissions is one that12 every non-carbon energy source, including nuclear power. The model to have in mind is not the hulking plant like Chernobyl. Instead, let's consider the small, reliable reactors that have13 the United States' submarines and aircraft carriers. In 50-plus years of cruising, they have had no14.

Carbon emissions and other greenhouse gases are the environmental challenge of our age. Nuclear power is one tool for15 ourselves of them — while keeping the lights on.

The key players in this hidden conversation are mycorrhizal fungi. These thread-like organisms connect tree roots, forming vast networks. Research from the University of British Columbia reveals that up to 90% of land plants depend on these fungi. Through this interdependent relationship, trees exchange nutrients like carbon and nitrogen. Older "mother trees" often act as hubs, sending extra sugars to younger saplings struggling in shaded areas — a phenomenon called "forest family connections".

When under attack, trees release chemical signals. A 2023 study in Nature Ecology & Evolution demonstrates that acacia trees (金合欢树) bitten by giraffes produce ethylene (乙烯) gas. Nearby trees pick up these chemical signals from the air within minutes and increase tannin (鞣酸) production, making their leaves bitter and less tasty. Similarly, pine trees attacked by beetles send out warning signals through fungal networks, pushing neighbors to boost defensive resins (树脂).

Not all interactions are cooperative. Some plants, like the ghost orchid, hack the network to steal nutrients from nearby trees without offering anything in return. Other species, such as black walnut trees, release toxins (毒素) to restrain competitors — a strategy called "biological warfare" by ecologists.

Understanding this "social network" challenges traditional views of forests. Logging dominant mother trees can collapse entire ecosystems, much like removing servers from the Internet. Scientists now advocate for selective cutting practices that preserve fungal networks, ensuring forests' resilience (适应力) to climate change.

As author Peter Wohlleben notes in The Hidden Life of Trees, "Forests are super-organisms with intelligence we're just beginning to decode." This silent dialogue beneath our feet reminds us that nature's deepest conversations often happen without a single word.

Take home books, magazines, or movie discs whenever you want. Books stay with you for three whole weeks, giving you plenty of time to get through every chapter. You can keep the dictionary for one month. Magazines stick around for a week, perfect for quick reads. And movies? You've got five days to watch them as many times as you like. Need a little extra time? No problem — renew books up to twice, and magazines or movies once. Just call or visit the library's website, and you're set.

Life gets busy, we get it — but late fees here are kept small, so you won't stress. For each day a book is late, you will be charged 25 cents. Magazines get a fee of 15 cents per day, and movies 50 cents.

Oops, lost a book or broke a disc? We'll help you replace it, with prices that fit the item — newer books cost a bit more, but older ones are easier on the wallet. And if you find that lost book later? We'll refund (退还) your money, no questions asked.

Got sick and can't return things on time? Just let us know, and we'll stop those late fees until you're feeling better. School holidays? Extend your borrows without extra charges — just tell us before the due date.

Come visit, borrow, and lose yourself in something great — we can't wait to see you!

Electric vehicles are quieter, easier to repair and maintain, and far better for the environment than traditional cars. Still, numbers of EVs on the road are trailing behind the cars they're supposed to replace, in part due to charging times. While fueling a gas car takes minutes, charging an EV can take much longer. The fastest public chargers (Level 3) can charge a battery to 80% in about 20 minutes, but slower and more common Level 2 chargers take hours, and Level 1 chargers at home can take days.

Scientists believe faster charging is possible by advancing battery science and charging technology. The goal is to approach refueling speed without compromising on safety or the long-term life of the battery.

The core challenge is electrochemistry. EV batteries have two electrodes (anode and cathode). During charging, lithium ions must move back to the anode. If they move too quickly, they can get "stuck", reducing efficiency and potentially causing a short circuit or fire. Venkat Srinivasan of Argonne National Laboratory compares this to "getting 100 people into a narrow room" — all trying to pass through one small door. Researchers are exploring new battery chemistries to create multiple microscopic pathways for ions, easing congestion.

Another approach involves smarter charging software. Current charging uses a steady flow of electricity, which slows as the battery fills. By adjusting the current based on the battery's condition — for example, increasing it when the battery is around 30% charged and resistance is low — researchers at Idaho National Laboratory believe charging can be made both faster and safer.

While research aims to replicate the gas-station experience, experts note that ultra-fast charging will mainly serve long trips or emergencies. For daily use, slower charging at home or work will remain the norm. "We drive to get from A to B," says Idaho National Laboratory's Tim Pennington, "not because we like going to the gas station. We don't need a ten-minute charge every day."

A visit became a turning point. Stuck in his village, Zhang noticed something new. The roads were paved, internet signals were strong, and the local government was offering support to those willing to start businesses. The beautiful mountains and fresh air, once taken for granted, now seemed full of potential. An idea began to form: what if he could build a future here, not just make a living there?

Using his savings and a small government grant, Zhang took a daring step. He transformed his family's old, empty house into a modern café, a place where city visitors could enjoy coffee while viewing the terraced fields. At first, neighbors were puzzled. "Who will come to the mountains for coffee?" they asked. Zhang persisted, learning about coffee beans and design online.

Today, "Mountain Cloud Café" is more than a coffee shop. It's a window for his village. Tourists come on weekends, and through his café, they discover and buy local specialties like mountain tea and dried fruits. Zhang has hired two local women, providing them with stable income. More importantly, his success has sparked a conversation. A few other young people, who once thought leaving was the only option, are now asking, "Could I come back too?"

"My dream isn't huge," Zhang says, looking at the lively scene outside. "I just want our home to thrive, so that our children might have a choice to stay." His journey from construction site to café owner paints a picture of modern rural China — one where returning wings bring new life.

Lily and I were huge Harry Potter fans. Since third grade, we had spent our lunch breaks pretending to fly on paper broomsticks (扫帚) and dreaming about receiving our own acceptance letters from Hogwarts. So when Lily showed me her most treasured book — a first-edition copy of Harry Potter and the Philosopher's Stone passed down from her aunt — my eyes widened in amazement. It wasn't just a book. It was a passport to our magical world.

After weeks of begging, she finally agreed to lend it to me. "Please be careful with it," she said as she handed it over.

I held it tightly against my chest and promised, "I'll guard it with my life!"

But that promise lasted only three hours.

On my way home, I held the book close, protecting it from the rain with my umbrella. Suddenly, a car drove through a puddle (水坑) nearby. I jumped back in surprise, and the book slipped from my hands. It fell right into the muddy water. I grabbed it immediately, my heart racing. The beautiful cover was now spotted with mud. When I opened it, my stomach dropped. There, on our favorite picture of Harry flying on his broomstick, was a tear running right through his broom.

That night, I couldn't sleep. I kept staring at the damaged page, feeling terrible. Part of me wanted to lie and blame a runaway dog. Maybe Lily would believe me. But deep down, I knew that running away from my mistake wouldn't make it disappear — not the tear in the book, and not the guilt in my heart.

So I decided to fix the book the way Lily would like: with a bit of magic. What if the tear wasn't just a tear, but a line of shining light? I pulled out my toolbox, found a gold pen, and took out some Harry Potter stickers I had been saving for years. My eyes landed on one particular sticker — a broomstick with wings. What if that broomstick had been flying beside Harry all along?
