A century ago, what had been the heart of China was reborn as something (complete) new. In 1925, the Forbidden City, once the exclusive domain of emperors, was transformed into the Palace Museum, a cultural institution dedicated to (safeguard) treasures that had long symbolized dynastic power. had for centuries stood as a walled-off (封闭的) seat of authority suddenly became open to the public. This was more than a change of function; it was a change of meaning. The Forbidden City became the (recognize) inheritance of a nation and ultimately, of the world.

Now, as the Palace Museum in Beijing celebrates its 100th anniversary, it is dynamic force shaping the future of culture. Its centennial ( 一 百 周 年 纪 念) is a (remind) that heritage is not static: It evolves, adapts and continues to inspire (generation). The 100th anniversary of the Palace Museum is not only a moment of national pride for China but also an occasion of global significance. It (mark) 100 years of transformation from the closed world of emperors to a vibrant public institution and from a national treasure house to an international platform. Its anniversary makes people reflect what heritage means in the 21st century. The Palace Museum shows that culture is not about looking backward in nostalgia (怀旧), about sustaining a living conversation between past and future and between nations and peoples.

Controlled environments for food production are not new. In 1999, Dickson Despommier and his graduate students explored the concept of vertical farming as a way to feed growing urban populations, leading to the broader use of the term in the 2010s and 2020s.

Vertical farming as a practice really didn't become popular in the United States until around 2020, but it has been used in countries like Japan and the Netherlands for decades, according to Koga, where greenhouses (the early form of vertical farming) in general are a much more integral part of their culture and food production.

Today, much of the work in creating more nutrient-rich food through vertical farming comes down to science. Currently, researchers are working to create seeds that are best suited for an indoor, controlled environment.

For instance, FFAR invested some $7.5 million in the PIP consortium to research varieties specific to indoor planting. "We've adapted plants through history," Reich told Built In. "We need to try to see if we can adapt plants specifically to indoor agriculture, to see if that makes it more economically practical for the future."

A. The research witnesses more than one sponsor.

B. This practice was copied by many other farmers.

C. They created floating boats to grow crops on waters.

D. Yet the term "vertical farming" caught on much later.

E. The older industry shapes vertical farming's operations.

F. Conventional methods adjust seeds for weather and soil.

G. Thus, vertical farming is adopted to reduce greenhouse gases.

Developmental psychologists warn that this phenomenon could have long-term effects. "Children need in-person interactions to build empathy (共情) and emotional regulation," said Dr. Daniel, a clinical psychiatrist. "Without those formative experiences, they're at risk of becoming adults who struggle to deal with relationships that involve complex social interactions and emotions." He described in his article America's Loneliness Epidemic: What Is to Be Done?

Studies indicate that prolonged contact with digital devices during critical developmental years can influence the growth of the prefrontal cortex (前额叶皮质), the part of the brain responsible for decision-making and empathy. These changes may leave children ill-equipped to navigate the complexities of adult relationships, creating a cycle of isolation. Teenagers are perhaps the most at-risk groups in the loneliness crisis. In the period of two decades, in-person social interaction among teens has dropped by 70%, replaced largely by digital communication. Social media platforms make it seem like people are connected, but they often make people feel worse about themselves and left out.

The damage to people's minds is really bad. Depression and anxiety rates among teenagers have increased, and studies by Dr. Vivek, link social media use to loneliness and confirm it. For teens, loneliness is not just an emotional state but a sign to life-threatening mental health crises. So it is essential to solve the problem of children's dependence on digital devices through various approaches. This includes establishing clear guidelines for screen time, encouraging activities that promote social development, and educating children about the importance of a balanced lifestyle. By doing so, we can create an environment that supports the overall well-being of children.

Like many European cities, Copenhagen became a city of cars after World War II. But in the 1970s, people fought back with mass bike protests that pushed the city to build a wide network of cycle lanes (车道). A recent study found that if all cities had as many, global CO₂ emissions from private cars could fall by 6%.

Still, even Copenhagen struggles to reduce car use. Cycle highways help people reach the city's end, but red lights slow them once they arrive. Planners hope the green waves will solve this. "It's so important to have the freedom on a bike to just ride along at a good speed," says Line Barfod, the mayor for technology and environment. "You can feel the city wants you — and supports you — going on a bike."

The new plan has faced little opposition. Yet at rush hour, some say the lanes are too crowded to enjoy the wave. Lars, who usually cycles too fast to ride the wave himself, thinks the city is reaching a difficult trade-off point. "We're at a point now where we need to choose between cars and cycles. If you give cycles more space, it will compromise the ability of drivers to access different spaces."

Copenhagen has approved a 602-million-kroner cycling package to improve the system, building the country's longest cycling bridge and upgrading lighting. The city has also set up 19 bicycle counters to study cyclists' speed and plans to adjust lights to match their flow. Experts say such measures represent a vision: moving people out of cars and onto bikes — to save energy, reduce pollution, and make cities more livable.

I had put so much time and emotional energy into applying, and I thought the rejection meant the end of the road for my science career.

So I was shocked when, not long after the email, Professor Mary Devon, who was running the programme, invited me to observe the work being done in her lab. I jumped at the chance, and a few weeks later I was equally shocked — and overjoyed — when she invited me to talk with her about potential projects I could pursue in her lab. What she proposed didn't seem as exciting as the original project I had applied to, but I was going to give it my all.

I found myself working with a robotics professor on techniques for collecting data from the desert remotely. That project, which I could complete from my sofa instead of in the burning heat of the desert, not only survived the lockdown but worked where traditional methods didn't. In the end, I had a new scientific interest to pursue.

When I applied to graduate school, I found three programmes promising to allow me to follow my desired research direction. And I applied with the same anxious excitement as before. When I was rejected from one that had seemed like a perfect fit, it was undoubtedly difficult. But this time I had the perspective to keep it from sending me into panic. It helped that in the end I was accepted into one of the other programmes I was also excited about.

Rather than setting plans in stone, I've learned that sometimes I need to take the opportunities that are offered, even if they don't sound perfect at the time, and make the most of them.

The way we think about learning and intelligence in educational settings is undergoing subtle but important changes. For many years, educational success was primarily measured through standardized tests and academic grades, which focused attention on a specific kind of logical and linguistic ability. This narrow focus, however, often overlooked other valuable forms of intelligence and ways of knowing that are crucial for a well-rounded life.

Howard Gardner's theory of multiple intelligence, proposed decades ago, suggested that human capability extends beyond verbal and mathematical skills to include spatial, musical, interpersonal, and intrapersonal intelligence, among others. While the theory has its critics regarding scientific validation, its cultural impact has been significant in prompting educators to consider a broader range of student strengths. In practice, this has led some schools to diversify their curricula and assessment methods to recognize and cultivate talents in arts, physical coordination, social leadership, and personal reflection.

Simultaneously, the concept of a "growth mindset," popularized by psychologist Carol Dweck, has gained considerable attention. This perspective emphasizes that intellectual abilities are not fixed traits but can be developed through effort, effective strategies, and guidance. Classrooms that foster this mindset encourage persistence through challenges, value the learning process over immediate perfection, and help students understand that struggle is often a part of developing new competencies. Research indicates that students who adopt this mindset show greater resilience and are more likely to take on challenging tasks.

These evolving ideas are gradually reshaping classroom culture, teacher-student interactions, and even parental expectations. The shift is not about lowering standards but about expanding the definition of success and creating educational environments where diverse learners can discover and develop their unique potential. This broader approach aims to prepare students not just for exams, but for the varied intellectual and personal demands they will encounter throughout their lives.

When I was twelve, my grandfather gave me his most prized possession — a leather-bound notebook filled with blank pages. "Every story begins with a blank page," he told me, his hands trembling slightly as he passed it to me. "But remember, it's not the ink that makes the story valuable. It's the courage to fill the page."

For years, the notebook remained untouched on my shelf. Its perfect, cream-colored pages seemed too beautiful to risk spoiling with my clumsy handwriting. I would open it occasionally, smell the faint scent of leather and old paper, then close it carefully, waiting for the "perfect" story to arrive.

The turning point came during my final year of university. Overwhelmed by academic pressure and uncertain about my future, I found myself staring at the notebook one rainy afternoon. On impulse, I picked up a pencil and wrote a single sentence about how the rain sounded like fingertips tapping on windows. Then another sentence followed, and another. For the first time, I wasn't trying to write something important — I was simply describing what I saw, heard, and felt.

That afternoon stretched into evening as I filled three pages with observations about my small dorm room: the crack in the ceiling shaped like Italy, the way shadows moved across the floor as the storm passed, the comforting weight of the old notebook in my lap. When I finally stopped, I realized something profound had happened. My anxiety hadn't disappeared, but it had been transformed — from a paralyzing fog into words I could see and manage.

Now, ten years later, I'm on my seventh notebook. I've learned that my grandfather wasn't just giving me paper and leather. He was giving me permission to be imperfect, to begin before I felt ready, to value process over product. Last month, when my own daughter turned twelve, I gave her a blank notebook with these words: "Don't wait for the perfect story. The imperfect one you write today will be more valuable than the perfect one you never write."

▲INSTANT COLOR TV

In 1962 there was only one TV channel in Sweden, and it broadcast in black and white. The station's Kjell Stepson, appearing on the news to announce that thanks to a newly developed technology, all viewers could now quickly and easily transform their existing sets to display color reception. All they had to do was pull a nylon (尼龙) stocking over their TV screen, and they would begin to see their favorite shows in color. Reportedly, hundreds of thousands of people, were taken in. Actual color TV transmission only started to appear in Sweden on April 1, 1970.

▲SAN SERRIFFE

In 1977 the British newspaper The Guardian published a special seven –page supplement(增刊) in honor of the tenth anniversary of San Serriffe, a small republic located in the Indian Ocean. A series of articles affectionately asked for more information about the beautiful holiday spot. Few noticed that every thing about the island was made up.

▲NIXON FOR PRESIDENT

In 1992 American National Public Radio's Talk of the Nation program announced that, Richard Nixon, in a surprise move, was running for President again. His new campaign slogan was, " I didn't do anything wrong, and I won't do it again." Accompanying this announcement were audio clips(片段) of Nixon delivering his election speech. Listeners responded immediately to the announcement, flooding the show with calls expressing shock and anger. Only during the second half of the show did the host John Huckleberry reveal that the announcement was a practical joke. Nixon's voice was copied by comedian Rich Little.

The study involved 498 participants aged 12 to 79, who selected one of the provided topics. Participants were then presented with short factual statements, followed by options to either learn more about the same topic (specific information seeking) or switch to a new topic (diverse information seeking). They could read up to 10 facts for each topic and up to 80 facts in total across multiple topics. The participants could spend as much time as they wished reading each fact and making their choices. Data were collected on how many facts each.

The facts were presented in a random order, and the participants could spend as much time as they wished reading each fact and making their choices. Data were collected on how many facts each participant read, whether they chose to continue reading within a topic or switch, and their self-reported curiosity in the material.

The results revealed significant age-related differences in information-seeking strategies. Older participants read more facts per topic, showing a clear preference for deepening their knowledge rather than broadening it. In contrast, younger participants exhibited more diverse information seeking, frequently switching between topics to explore a wider range of materials. For each additional year in age, participants were slightly more likely to stay within a topic and less likely to explore a new one.

Additionally, the researchers found that participants' self-reported curiosity was related to their information-seeking choices. Participants who rated themselves as more interested in a fact were more likely to continue within the same topic.

This has implications for how new information should be communicated to different age groups in order to best support motivated learning. This consideration has a vast range of potential applications, from educational course design to museum exhibit arrangements to the provision of health information.

The scientists revealed they had reprogrammed cells from an Asian elephant, the woolly mammoth's closest living relative. These changed cells can grow into any kind of elephant cell. The research team has analyzed 50 changes to the genetic code of the Asian elephant to give it the characteristics it needs to survive and thrive in the Arctic. These characteristics include a 10-centimeter layer of insulating (绝缘的) fat, five different kinds of hair including some that is up to a meter long, and smaller ears that will help the hybrid tolerate the cold.

Colossal believes that bringing the woolly mammoth hybrid to life could possibly help restore the fragile Arctic tundra (冻原) ecosystem, which is at risk as the world warms. The company has claimed that mammoths, if they should return to their natural habitat in the Arctic in sufficient numbers, would help slow down frozen soil melting. Some scientists believe that, before their extinction, animals such as mammoths and horses kept the earth frozen underneath by walking on the grass, knocking down trees and pressing snow tight. One small study in Siberia published in 2021 suggested that the presence of large mammals such as horses and reindeer resulted in lower soil temperatures in the protected area where they were kept compared with land outside that area.

Colossal announced other plans to bring some animals back to life such as the Tasmanian tigers in 2023 and the dodos in 2024, but its work on the mammoth has been going on longest.

I left for the land of warmth and vitamin C, thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness. Swimming pools, wine tasting, and pink sunsets (at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part — particularly to my taste, dulled by months of cold weather root vegetables — was a 7 a.m. adventure to the Sarasota farmers' market that proved to deserve the early wake-up call.

The market, which was founded in 1979, sets up its tents every Saturday from 7:00 a.m. to 1 p.m., rain or shine, along North Lemon and State streets. Baskets of perfect red strawberries; the red-painted sides of the Java Dawg coffee truck; and most of all, the tomatoes: amazing, large, soft and round red tomatoes.

Disappointed by many a broken, vine-ripened (蔓上成熟的) promise, I've refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they're unfailingly dry, hard, and tasteless. But I homed in, with uncertainty, on one particular table at the Brown's Grove Farm's stand, full of fresh and soft tomatoes the size of my fist. These were the real deal and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn't be experiencing again for months.

Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown's Grove Farm was one of the suppliers for Jack Dusty, a newly opened restaurant at the Ritz Carlton, where — luckily for me — I was to have dinner that very night. Without even seeing the menu, I knew I'd be ordering every tomato on it.

The Lantern Festival, celebrated on the fifteenth day of the first lunar month, marks the grand finale of Chinese New Year celebrations. With origins (date) back over 2,000 years to the Western Han Dynasty, this tradition has evolved an elaborate cultural spectacle that attracts millions of participants annually.

makes this festival particularly significant is its unique fusion of religious, social, and artistic elements. Families gather to solve riddles written on lanterns, activity that promotes intellectual engagement across generations. Meanwhile, lion dances and dragon parades fill the streets, (create) a vibrant atmosphere that few other cultural events can match.

Recent years (see) innovative adaptations of this ancient tradition. (be) traditionalists to object to these modern interpretations, they would be overlooking the festival's historical capacity for reinvention. In fact, contemporary celebrations now incorporate LED lanterns and digital projections alongside (century) -old paper crafts.

This delicate balance between preservation and innovation represents a challenge that cultural custodians face worldwide. The Lantern Festival's (endure) popularity suggests that when managed thoughtfully, tradition and modernity need not be mutually exclusive but can instead enrich another.

In some6, people express more nonverbally than verbally. If you ask an obviously depressed person, "What's wrong?", and he answers, "Nothing. I'm fine," you probably won't7 him. When an angry person says, "Let's8 the subject. I don't want to talk about it anymore!" actually he hasn't9 communicating. His withdrawal and10 continue to convey emotional meaning.

One study showed that 93 percent of the11 was communicated by the tone of the12 and facial expressions, while only 7 percent of the speaker's attitude was conveyed by words. It is13 that we express our emotions and attitudes more nonverbally than verbally.

Nonverbal communication expresses14 or feeling beyond words. Universal emotions, such as happiness, fear, and sadness, are expressed in a15 nonverbal way throughout the world. There are, however, nonverbal differences across cultures that may be a source of16 for foreigners. For example, feelings of friendship17 everywhere but their expression18. It may be acceptable in some countries for men to embrace each other and for women to hold hands; in other countries these acts of19 may be considered shocking. In order to correctly20 another culture's style of communication, it is necessary to study the "silent language" of that culture.

When I landed in a small town in New Zealand as an exchange student, I thought I was ready for everything — new faces, language barriers, strange social patterns and even homesickness. Still, the smallest things made me feel out of place.

Luckily, the Wilsons, my host family, did everything they could to help me settle in — driving me around, sharing meals, and even letting me use their kitchen when. I. missed Chinese food. With their warmth and support, everything seemed to fall into place.

But at school, small moments felt bigger than I'd imagined. In our first literature class, we discussed a Hemingway story. Everyone jumped in actively, while I struggled to speak up. My desk-mate encouraged me, "Next time, just speak up." I nodded, forcing a bitter smile.

And just like that, I found myself in another cultural trap, Mrs. Wilson's birthday dinner. At the table, I answered politely but kept mostly to myself. Mrs. Wilson noticed my silence and gently asked, "You alright, sweet girl? You' re so quiet tonight." My face reddened. Was my silence seen as cold, rather than polite?

That night, restless and wide awake, I wondered if I needed to laugh louder, speak faster; or hide parts of myself just to feel I belonged. Questions flooded my mind, none with answers.

A few days later, our teacher announced there would be a Culture Festival next week. "You' ll prepare a stand to share your own culture — food, crafts, customs ... anything meaningful. You can not only display your culture but also make it interactive, allowing people to try new things, learn traditional skills. or share stories and cultural symbols," she said. The class lit up with excitement. I sat frozen, mind racing: how could I share my traditions in English? The thought made my stomach twisted (扭曲). Yet, I gathered myself with a deep breath and signed up. After that, I threw myself wholeheartedly into preparations, until the day finally came.

Now the project has led to major advances in satellite communication and mobile phone development. In 2021 the Tiantong satellites formed a network covering the entire Asia-Pacific region. In August, 2023, Huawei released the world's first smartphone that supported satellite calls, by directly connecting to the Tiantong satellites. On December 18, 2023, a 6.2-magnitude earthquake hit Gansu, causing widespread communication interruptions. Thanks to the Tiantong satellites, many of those trapped in the disaster were able to connect with the outside world through the satellite calling function on their smartphones.

Direct satellite connectivity for mobile phones was previously believed to be impossible. To reach a small smartphone, the satellite needs to produce a very powerful signal. When a large number of different high-power signals flood the satellite's transmitting antenna(传输天线)at the same time, they can lower the quality of satellite calls and, in severe cases, cause the entire system to collapse. Since the 1970s, nearly all the previous commercial communication satellite networks have experienced such major failures. This issue, known as PIM, was once a bottleneck for further development of satellite communication technology.

To solve this problem, Chinese physicists have established a physical model that can predict the occurrence of PIM with incredible accuracy. Based on this work, Chinese scientists developed the world's first PIM simulation(模拟)software, which, in turn, helped Chinese engineers develop a series of effective technologies against PIM. These key scientific and technological breakthroughs enable the Tiantong satellites to transmit and receive electromagnetic(电磁)waves in 800 different frequency bands and, meanwhile, resist daily temperature changes of up to 160℃.

Solving the PIM problem in such tough working conditions is extremely challenging. The success of Tiantong exhibits the hard work of the project team and marks China's leading position in this technical field around the globe.

When talking to children, many adults might say things like "Let's be scientists today!" or "You're such a good scientist!". But this kind of identity-focused language, which focuses on science as an identity rather than activities and actions that people do, can be demoralizing for young children. One study showed that children as young as four, especially girls, kept their interest longer when their cue to participate in science activities was "Let's do science" rather than "Let's be scientists."

One possibility is that when thinking of a scientist, children might picture a white man. If they don't share that identity, they lose interest in an activity designed "for scientists." This stereotypical (刻板印象的) belief that science is reserved for only certain-kinds of people emerges surprisingly early. By the first grade, when asked to draw a scientist, children tend to draw a white man.

The good news is that language cues can also be directed to promote engagement with science. Describing science as actions that we take, for example, seems to protect young children's interest in science over time. But it's also true that teenagers are actively trying on and ultimately forming different identities for themselves. So in contrast to its demoralizing effects on young children, identity-focused language may help teens stay interested in science. In another study, cueing a future identity based on science (such as "scientist" or "doctor") motivated middle schoolers to do more homework and was associated with higher grades.

Consequently, adults had better use different language cues for children of different age groups to maintain their curiosity about science.
