Known for his deep (understand) of Chinese literature, German sinologist (汉学家) Martin Woesler recently made his first visit to the ancient Silk Road hub of Dunhuang in Northwest China's Gansu Province, made a deep impression on him because of its unique cultural charm and the local friendly people.

Woesler traveled northwest (attend) the Fourth Dialogue on Exchanges and Mutual Learning among Civilizations, held in Dunhuang recently. Before setting out, Woesler had read a considerable number of books, and found many vivid (description) of Dunhuang. However, when the words and images (contain) in the books were confirmed by his own eyes, Woesler found himself very moved. a lover of Chinese culture and literature, he has worked in China for over 30 years, and yet despite his lengthy stay in China, Dunhuang ended up (provide) him with a cultural experience unlike any other.

Woesler also visited several of the city's most iconic sites he had long looked forward to seeing. Standing in front of the Mogao Grottoes for the first time, he was (deep) impressed by an unexpected sense of cultural connection that bridged both time and geography.

Woesler's connection with China began 38 years ago at a poetry reading in his hometown. A Chinese poem fired his interest in Chinese culture and eventually (lead) him to study at Peking University in Beijing, thus inspiring lifelong journey into Chinese culture.

Some students were1 to go to summer camp while others were just happy to stay at home and rest. However, summertime for Susanna2 only one thing: the cottage.

On sunny days at the cottage, there was so much3 ! The sunshine made the lake shine like a diamond. The gentle wind4 the leaves on the trees, sounding like a waterfall. Susanna was5 to go swimming with her parents in the clear lake on the hottest days. She also liked rowing herself on a paddle board (浆板),6 she often fell off it!

On7 days, the family would stay indoors, watching movies or8 challenging jigsaw puzzles. At night they would do some9 , embracing (拥抱) the wonder of literature while listening to the sounds of the rain falling on the roof.

Susanna loved the way her whole family spent the summer there. However, the10 was her cousins' visit. They would light a campfire at night, singing and dancing to music outdoors. Once inside,11 themselves under blankets, Susanna and her cousins would tell12 and laugh to tears until the adults found them and told them to be quiet.13 , they would fall asleep, one by one, until only Susanna remained14 . She would fall asleep to the gentle snores of exhausted children, wishing that summer at the cottage would never15.

Last May, I met Paul. He told me that it was his first time in China. He talked to me with great excitement about the history, migrations, and discoveries in my region of China. He spoke of the Shu-Yandu Dao (the Southern Silk Road), the travels of the 17th-century Chinese explorer Xu Xiake, the Tea Horse Road and the early 20th-century American botanist Joseph Rock. He also talked of Xuanzang. Paul considered many of them heroes and in a sense Chinese pioneers of slow journalism.

I decided to accompany Paul on his walk toward Yunnan. On September 28, 2021, we set out. Our days were simple: walk, eat, sleep, and repeat. We woke up at sunrise, set off in high spirits, and rested at sunset, dragging ourselves into exhausted sleep.

We met many people on the road. Some were curious, surrounding us and watching us; some gave us directions; some invited us into their home to take a rest; some spoke of the charm of their hometown. We met many beautiful souls, simple souls and warm souls. We were walking with our minds.

Together, we were impressed by the biodiversity of the Gaoligong Mountains. As I walked on ancient paths through mountains, I seemed to hear the antique voices of past travelers urging me to be careful on the road.

Looking back on the more than 200 miles I walked with Paul, I came to a realization. Walking for its own sake, while healthy and admirable, is only a small part of the benefit of moving with our feet. A deeper reward is rediscovering the world around us, shortening the distance between each other, and sharing each other's cultures.

Teens Are Flocking to AI Chatbots. Is this Healthy?

A new report from Common Sense Media says that 72 percent of teens surveyed have used AI companions, and 33 percent have relationships or friendships with these chatbots.

The language that AI companions use, the responses they make, and the empathy they show can make a user feel as though they truly understand and sympathize. These chatbots can make someone feel liked or even loved. They are programmed to help users feel like they've made a real connection.

You might think your kid won't get attached, that they will know this chatbot is an algorithm designed to give responses based on the text inputs they receive; that it's not "real." But a fascinating Stanford University study of students who use the app Replika found that 81 percent considered their AI companion to have "intelligence," and 90 percent thought it "human-like."

On the plus side, these companions are sometimes touted(吹捧，兜售)for their supportiveness and promotion of mental health; the Stanford study even found that 3 percent of users felt their Replika had directly helped them avoid suicide. If you're a teenager who is isolated or struggling to make friends, an AI companion can provide much-needed companionship. They may offer practice when it comes to building conversational and social skills.   Chatbots can offer helpful information and tips.

But a suit(诉讼案)filed in 2024 claims that Character. AI encourages self-harm in teens and violence towards parents who try to set limits on how often kids use the app. Then there's privacy: wired, drawing on Mozilla's research, labeled AI companions a "privacy nightmare," many crawling with data trackers that might control users into thinking a chatbot is their soulmate, encouraging negative or harmful behaviors.

Remind kids that human friends offer so much that AI companions don't. In real life friendships are challenging, and this is a good thing. Remind them that in their younger years, play is how they learned new skills; if they didn't know how to put LEGO s together, they learned with a new friend. If they struggled with collaboration and cooperation, play taught them how to take turns, and how to adjust based on their playmates' responses.

Have you ever told yourself, "Just five more minutes" before bed, only to find yourself still awake an hour later? If so, you're not alone. Sleep procrastination — delaying bedtime despite knowing the consequences — isn't unusual.

The truth is, sleep procrastination is more complex than poor time management. Both psychological and emotional factors make it difficult to simply go to bed earlier.

During the day, we are faced with responsibilities: school, homework, and endless tasks. At night, we finally feel in control of our time. We seek distractions like scrolling through social media or playing games. These might feel like stress relief, but staying up late leaves you exhausted the next day.

However, the problem is that most of these activities are designed to keep us addicted. Social media apps and video platforms trigger dopamine(多巴胺)releases, making it hard to stop. It's a vicious cycle.

But it's one we can break. First, we need to find moments of pleasure during the day, so we don't feel the need to steal time at night. Furthermore, a friendly sleeping environment is also crucial. Avoid overstimulating activities like intense gaming or action movies right before bed.

Sleep procrastination may seem like a small win. So the next time you think, "Just five more minutes," choose self-care. Your future self will be grateful.

A. Instead of resting, we often stay up late as a form of rebellion.

B. Our brains seek the next small hit of pleasure, even when our bodies are begging for sleep.

C. Therefore, creating a consistent sleep schedule is the most effective solution.

D. Stop blaming yourself for a simple lack of self-discipline.

E. Dim the lights, avoid screens, and wind down with a book or a calming activity.

F. The real victory is waking up refreshed.

G. This cycle can be broken with strong determination alone.

That technology is known as a gene drive, so called because it uses genetic engineering to drive certain features through a population. Those characteristics need not be harmful: they might become stronger against disease among crops or, perhaps, greater tolerance to warming waters on the part of corals. And if the species in question were the three types of mosquito responsible for spreading malaria, it could save close to half a million lives a year, many of them children. The same approach could be used against other diseases such as Lyme disease, and Zika. Gene drives also offer us a potential weapon against foreign species such as foxes, mice, rabbits and rats, which are threatening native species in some parts of the world.

Normally genes have a 50:50 chance of being passed on during reproduction. Gene drives tip the evolutionary scales. One area of research focuses on genes that can copy themselves to the second, ensuring that they will be passed on by all offspring (后代). Like many technologies, however, gene drives may lead to bad outcomes as well as good. They could in theory make a species extinct. One concern is practical: removing a species from the food chain could have unintended consequences, particularly if gene drives can move to a closely related species. Another relates to governance. Genetically modified crops can be kept relatively contained; animals carrying gene drives could be mobile and respect no borders. One country's decision to use gene drives will have consequences for its neighbors. A third worry concerns improper uses of the technology, and not only by states. A mosquito, engineered to inject a poisonous substance, could be used as a weapon. But putting the brakes on research may pay real costs: not just the annual rising number of deaths taken by malaria and other killers before an answer is found, but also slower progress towards making gene drives safer.

A 2024 study tracking 500 students across three senior high schools revealed that those using Intelligent Class improved their math and English scores by an average of 12% over one semester. The platform's strength lies in its "diagnostic learning" model: it identifies knowledge gaps by analyzing students' answers, then generates targeted practice problems. For instance, a student struggling with grammar rules in English will receive customized exercises focusing on tense consistency, while their peers proficient in the area get advanced tasks.

However, educators caution against overreliance on such tools. "AI can enhance learning, but it shouldn't replace critical thinking," notes Ms. Li, a senior English teacher at Beijing No. 2 Middle School. She observed that some students began to rely solely on the platform's answers, losing the ability to explain their reasoning — a phenomenon termed "cognitive laziness" by education psychologists. This highlights a key challenge: balancing technological support with the development of independent problem-solving skills.

Proponents argue that Intelligent Class frees teachers from repetitive grading, allowing them to focus on interactive lessons. In a survey of 100 teachers, 78% reported spending more time on one-on-one guidance after adopting the platform. The AI tool also democratizes education, as students in underprivileged areas now access the same high-quality resources as their urban counterparts.

The future of AI-assisted education, experts say, lies in "human-AI collaboration." Schools are experimenting with hybrid models: students use Intelligent Class for practice and feedback, then meet with teachers to discuss concepts and apply knowledge in real-world scenarios. As Dr. Wang, an education technologist, puts it, "The goal is not to let AI teach, but to let it empower both teachers and students to learn more effectively."

She immediately contacted her neighbor Hillary, who had experience renovating RVs. Hillary found a used RV in Louisiana priced at $6,095 — an amount that was affordable for Cherrie, yet still represented a significant financial stretch. To gather the necessary funds and resources, Cherrie turned to social media, sharing her compassionate plan on Facebook. What followed was entirely unexpected: her post triggered a "chain reaction." Strangers from various places responded generously, sending warm clothes, monetary contributions that covered the entire cost of the vehicle, and donations of new furniture and essential kitchenware. Linus, the father of a former student, offered to use his truck to tow the RV to the disaster area. Through a charity called "Hope for Crisis," they connected with the Ryan family — Destiny, Ryan, and their daughter Phiona — who had lost everything in the hurricane.

During the journey to deliver the RV, an unexpected delay occurred when a tire needed replacement. However, upon learning about the group's charitable mission, the owner of the tire shop was so moved that he charged them only the wholesale cost, refusing any profit.

When they finally arrived, Destiny hugged Cherrie tightly, and Phiona jumped up and down asking, "Is there a bed for me inside?" Cherrie later said, "This wasn't just my kindness. It was hundreds of ‘angels on earth' working together." What started as a small thought had turned into a huge gift of hope.

Last month, I finally received the letter of admission from Peking University. With trembling hands, I opened it and was overjoyed. It was the(good) news I had ever had! The moment I had been dreaming of arrived. I felt a great weight(lift) off my shoulders. My hard work had paid off, and a new chapter of my life was about to begin, filling me with excitement for all possibilities that lay ahead.

Artificial Intelligence is changing our world in numerous ways. One of its greatest (advantage) is that it can process huge amounts of data efficiently. Self-driving cars, rely on AI to sense the environment, are a typical example. Companies aim to develop even smarter systems in the future. However, it is crucial (ensure) that these technologies are used (responsible).

Chinese paper-cutting is a wonderful art form with a long history. I still remember the first time I (see) my grandmother cut a piece of paper into a beautiful butterfly. She (master) the basic skills of this craft long before I was born. With a pair of sharp scissors, she created delicate patterns, (leave) me in complete amazement. To me, it was not just a piece of art; it was a piece of our culture.

One year, a grand art competition was1 in the nearby city. The winner would receive a scholarship to study art abroad. Elara knew this was her chance. With passion and determination, she was2 in creating a masterpiece, staying up late.

When the day of the competition arrived, Elara's heart swelled with hope. She traveled to the city with her painting,3 about her work. Despite her initial excitement, Elara's painting did not win. She watched as others celebrated, her heart heavy with4. She returned to her village feeling defeated, her dream seemingly shattered (粉碎的).

For weeks, Elara couldn't bring herself to pick up a brush. One evening, as she sat by the river, a gentle voice broke her daydream. It was an old, wise woman from the village.

"Why do you look so down, child?" the old woman asked. Elara poured out her heart, sharing her fears and disappointments. The old woman listened5 before speaking. "Do you know why the river never stops flowing?" she asked. Elara shook her head. "Because it doesn't give up," the old woman said. It6 obstacles, but it finds a way around them. Your dreams are like this river. As long as you don't give up, you will find a way.

Elara7 the old woman's words. The next day, she picked up her brush again. She painted with renewed vigor, not for the sake of winning but for the love of her art. She8 her failures and continued to improve.

Years passed, Elara's persistence finally9. Her paintings began to attract attention in her village and beyond. She eventually got the scholarship she had once dreamed of, but more importantly, she learned the true meaning of10 and resilience.

I'm not a3 writer of food, since I4 review restaurants in the traditional sense. Instead, I'm more interested in food's5 and what it reveals about cultures. For instance, how did Mexican cacao get to Europe, and how did the Czech kolache find its way to Central Texas? Knowing the6 behind such things is a7 in history that goes far beyond a pretty dish presented on a plate.

There's not a more8 way to get a taste of a place than by taking food-themed tours. Many tours include market visits, which are the best way to experience life as a(n)9. Markets are the hearts of communities and reveal not only the way a culture eats, but also how they10 and interact.

Traditions and culture are deeply11 food and through cooking lessons. The number of cooking classes that I've12 around the world can't be counted. Now, I'm no Alain Ducasse in the kitchen, and rarely do I13 at home. However, including these types of classes into my journey is something that I14. And even though the acquired cooking skills don't translate back to my home kitchen, the cultural15 still resonates (产生共鸣).

If you want energy and strength for an ideal workout, you need fuel. A fed workout will provide your body with power. Eating before exercise may help you sustain longer sessions and lift heavier weights. Muscle preservation is also an essential component of strengthening your body. Nitrogen (氮) is critical for processing protein that builds healthy muscles. People tend to lose less nitrogen during a fed workout than a fasted one.

Many fitness enthusiasts are not on board with this idea. They report feeling sick and inactive while trying to exercise after eating. With a fasted workout, you may not get the usual indigestion. Experts for fasted workouts further claim that eating afterwards makes your body use its fat reserves for energy, meaning you will burn more fat. It can cause a sudden drop in your blood glucose (葡萄糖) levels, and you may feel dizzy. You may even be more likely to overeat.

Not all foods are created equal. For example, if you choose a fed workout, you'll probably lose a lot of water during an intense training, so you should consider drinking some beforehand. With a fasted workout, it would help if you had some nutrition right after your session is complete. Drink some water. Then, have a light meal or nutritional snack.

Deciding when to eat for an ideal workout is a personal choice. Both fasted workouts and fed activities have their benefits and shortcomings.

A. However, a fasted workout might not work for you.

B. How your body will respond is based on your workout intensity.

C. These benefits can result in burning more fat and shaping a slimmer body.

D. To eat or not to eat, that is the question on many fitness enthusiasts' minds.

E. Think thoroughly and discuss with your fitness instructor before taking a choice.

F. Knowing what to eat for an ideal workout is just as important as knowing when to eat.

G. A person doing a 30-minute session a day may not have a problem with fasted workouts.

Even in today's tough economy, for those with six-figure incomes credit is easy to come by. Credit companies may have cut back offerings to those in lower income brackets due to the recent credit reforms, but there seems to be little or no effect on high income earners. Their being able to get credit without difficulty gives them a false sense of security that makes them spend way more than their incomes can afford. That's why they accumulate credit card debt faster than average.

Many higher income earners feel like they are making lots of money now, and believe that they will continue to make big money. This may reduce their feeling that they need to watch their money carefully now. Hand in hand with that, many of them probably believe that they are making more money than they really are — or said another way, the money they make will go farther than it really does.

Meanwhile, many young professionals who are earning good incomes don't come from particularly privileged backgrounds, and their reference point may be that they are making twice (or more) than their parents were — so they spend like that as well. They don't take account of the effect of inflation, which means that the cost of living is much higher than that in their parents' generation. Further, the more you earn, the more you pay in tax. Rather than focusing on after-tax incomes, many high income earners only look at the top line figures. A $ 100,000 income before tax is only about $ 70,000 after tax.
