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!

Melody stood at the edge of the half-pipe, heart beating fast. The steep ramp (坡) challenged her to drop in. She bent her knees and spread her arms a little to keep her balance. When she reached the other side, she went up high. Then she dived back down and up again, enjoying the thrill of the ride.

Patrick, another skater, cheered, He was a year ahead of Melody in school, but they'd become friends at the skate park. "I got it on video." Mom said, waving her phone as Melody rode away from the half-pipe. Melody smiled. She wanted to be able to show her faraway cousins her favorite activity.

When it was her turn again, she set up and — her skateboard suddenly shot out from under her! Her arms moved around wildly, and then she was on the ground. "Ow! My wrist!" she whimpered.

Patrick rushed over. "You OK?" Mom was there a split second later. "Hope you didn't get that on video, Mrs. B." Patrick joked. Melody sniffed. "Ha." She tried to move her hand and winced (痛得呲牙). "Let's get you to the doctor, sweetie," Mom said. Two hours later in the Medi-Center. Dr. Das finished up the cast (石膏) and said, "Six weeks, and you'll be as good as new."

On the way home, Melody and her mom passed the skate park. Melody read the big sign painted on the wall: NO FEAR. "Six weeks, and you'll be as good as new." No fear. Melody thought about these words a lot over the next six weeks. But every time she replayed the crash in her mind, her stomach flip-flopped.

Still, by the time the cast came off, Melody's board was calling her name. She and her mom returned to the skate park. "Just take it slow," Mom called from the bench. Melody skated around for a while. She concentrated on the board under her feet and popped a kickflip.

It felt good, but she missed the half-pipe more than anything. "Hey, Mel, welcome back!" Patrick called. Melody smiled back.

Mount Tai, a towering peak in Shandong province, China, is famous for its steep terrain with over 7,000 steps. Climbing this mountain is challenging. especially for the elderly and those with mobility issues.

Fortunately, AI-powered exoskeletons (外骨骼机器人) are making the journey simpler. These robotic legs, (weigh) only 1.8 kilograms, are designed to wrap around users' waists and legs, offering assistance (ease) the burden on legs. Users reported feeling like someone was pulling them uphill, making the climb much easier. However, some mentioned (convenience) in using the device for activities like tying shoelaces or using the bathroom. these issues, the exoskeletons are seen as a "true blessing" for senior citizens and the mobility-impaired visitors. This innovation not only aids mountain climbing highlights potential applications in elderly care, growing market in China, in the population of seniors is rapidly increasing.

The smart elderly care market (estimate) at 6.8 trillion yuan last year. Kenqing Technology, the co-developer, is eyeing this vast market now and has launched an exoskeleton (specific) designed for elderly users.

To fully unlock the potential of elderly care robots, industry insiders told Xinhua News Agency that stronger policy support is needed to promote the large-scale application while keeping prices (afford) for all.

Several new studies seem to show not only that water does, in fact, have a taste, but that we might have taste buds (味蕾) that respond directly to it.

We now know that there are at least five basic tastes: salty, sour, sweet, bitter and umami. Researchers have sought to solve the issue once and for all. They've figured out an experiment that seeks to identify any water-sensing taste receptor cells (TRCs) on the tongues of lab mice.

The team first used a technique known as genetic knockout to silence different types of TRCs, in order to remove the possibility that those cells might accidentally discover some other taste within the water besides the water itself. It turned out that the acid-sensing sour TRCs were still firing actively, indicating these cells might have a double purpose, capable of distinguishing water or acidic fluids.

So if you're on the side of the debate that argues that water is flavorless, you might still be correct. The study also opens up the possibility that our tongues and taste buds might be doing more than merely providing us with a sense of taste. If this study doesn't prove that water is the sixth flavor, it might still be the first evidence of a whole other sense entirely: a water sense.

A. Well, perhaps we have.

B. Actually, we have a sixth taste for water.

C. Our taste buds are tied to a flavor of water.

D. So it's perhaps a bit doubtful that water doesn't seem to have any flavor.

E. But water isn't senseless, at least it doesn't appear that way according to this research.

F. They then washed their mouths with water to see if any cells were still responding.

G. If there is a sixth taste for water exists, then there should be evidence somewhere in the mouth or tongue.

The experiment had 29 male volunteers aged 19-27 with normal body weight. Volunteers were divided into two groups. The experimental group added 1,500 extra calories every day like chocolate bars and potato chips for five days, while the control group kept their normal diet. Researchers used whole-brain MRI to examine the brain insulin (胰岛素) activity. They also did blood tests and measured liver fat to check metabolic (代谢的) changes.

The results showed after only five days of over eating, volunteers developed more liver fat and showed changed insulin sensitivity in brain regions related to reward processing. In psychological tests, they became less sensitive to reward and more sensitive to punishment. Surprisingly, these changes happened without any big weight gain. This means that the brain reacts to what we eat before we see any physical changes. Dr. Kullmann said, "The speed of these neurological (神经系统的) changes surprised us — they are detectable before any visible weight changes."

Perhaps the more worrying was the long-term effects. One week after volunteers returned to their normal diets, memory-related areas of the brain showed lower insulin sensitivity. The brain's white matter, which helps the nerves talk to each other well, also showed changes. It appeared like those in fat people; raising important questions about how short-term overeating could lead to long-term health problems.

The study's findings go against what we usually think about occasional overeating. It brought no big changes in weight but in brain, which might make it harder for people to eat healthily in the future. The reward system might create a vicious cycle where unhealthy foods become more attractive while healthy choices seem less rewarding. As Dr. Kullmann concludes, "Our brains are more sensitive to dietary changes than we realized— what we eat today may influence how we think and choose tomorrow."
