Though4, my parents had him sit down at the table. My mum started asking questions, David turned out to be a college student who5 to cover college costs and rent. He'd6 his apartment and was living out of his car… He answered every question and7 thanked my parents for letting him eat with us. Finally, the8 ended when my father said, "Bette, that's enough. Let him9."

We all ate in10 for the next couple of minutes. Then my dad asked, "David, how is your11?" "Sir, there is some noise, but it's okay for now. It's12 of you to ask." My dad continued, "Let's check it out before you leave so you are13 on the road."

In the following years, each of us was14 to invite someone for Thanksgiving dinner. It was a welcome new tradition for our family: the act of15 not only food but also our blessings.

Hike with at least one other person. Not only is hiking more fun with a friend, it is also safer. If you decide to hike alone, make sure that you let someone know where you are going and when you plan to be back. This way, if you get lost or injured, someone will know where to look for you and when to send help.

Have plenty of water. Even if you are only going for a short hike, it is important to have lots of water on hand so that you avoid dehydration (脱水). Plan to bring one liter of water per person per hour of hiking. So make sure to drink your water frequently, even if you are not very thirsty.

Wear correct kinds of clothing. You should wear comfortable, closed-toed shoes and thick socks. Your clothing should be comfortable and easy to move around in. Clothing that is too loose might catch on rocks or branches.

If you have not exercised in a very long time, do not try to go on an 8-mile hike up a mountain on the hottest day of the year, Instead, you should start gradually. First, go for regular walks in your neighborhood. Next, you should try to find places to walk on steep hills or rocky soil.
 

A. Don't take a too long trip at a time.

B. Make sure that your body is prepared.

C. You can begin to dehydrate before you even realize it.

D. If you get injured, your friend will be able to go and get help.

E. But clothing that is too tight might become uncomfortable as you walk.

F. With enough practice, you can take longer hikes across more challenging landscapes.

G. If you are going on a long hike, you might want to bring an extra pair of socks just in case.

This ability comes in handy for detecting mouth movements, allowing the device to detect low-volume or even silent speech. That means you can whisper or mouth a command, and the glasses will pick it up like a lip reader.

"For people who cannot vocalize sound, this silent speech technology could be an excellent input for a voice synthesizer(合成器)," said a doctoral student. The tech could also be used by its wearers to give silent commands to a paired device, like a laptop or a smartphone.

It is proved that EchoSpeech could recognize 31 commands and connected data with error rates of less than 10 percent. The speakers and microphones are placed on different lenses on different sides of the face. When the speakers give off sound waves around 20 kilohertz, it travels in a path from one lens to the lips and then to the opposite lens. As the sound waves from the speakers reflect and diffract after hitting the lips, their distinct patterns are caught by microphones and used to make "echo profiles" for each phrase or command. It effectively works like a simple, mini sonar system.

"Because the data is processed locally on your smartphone instead of being uploaded to the cloud, privacy-sensitive information never leaves your control," a professor noted. Plus, audio data takes less bandwidth to transmit than videos or images, and takes less power to run as well.

The Azores

The trips offer the opportunity to work on carefully selected projects with famous scientists while also enjoying meetings with some of the world's most attractive sea creatures in water. It allows participants to join a research team in the Azores that's studying the animals to support future protection of the species. Advanced diving experience is required.

Red Sea, Egypt

Combining an opportunity for world-class diving with being part of an important research effort conducted by Hurghada Environmental Protection and Conservation Association. The seven-night trip includes learning how to gather water data with the latest scientific equipment and conducting onboard and underwater experiments.

Australia

Explore Queensland, Australia, while also supporting a registered charity that rescues farm animals from abuse, neglect, and situations where they're in danger. Participants help with daily cleaning of barns (牲口圈) and cages, feeding, health checks, light repair, monitoring animals' movements, and intensive care of ill, old and baby animals. The experience includes free accommodations with WiFi and a swimming pool.

Romania

Work with bears at Romania's largest bear sanctuary (庇护所), a place that was created as a heaven for bears that have been treated in a cruel way. Located in the Carpathian Mountains, the sanctuary needs volunteers to help with preparing food, monitoring animal health and leading conservation tours. The sanctuary is home to 84 bears, with 20 more due to be rescued.

Ethan had always lived by checklists — precise and detailed. At school, he double-checked his answers, rewrote notes in perfect handwriting, and organized his pens by size and color. But the world often refused to follow his plan. A missed question, a group project gone off track, or even a messy desk could send him into hours of self-blame.

During a school event, he was struck by what was advertised on the poster of a pottery class, "Join us. Create, relax, and just be yourself." He eagerly signed up, hoping it might ease the anxiety that had wrapped him around for long.

On the first day of their pottery workshop, Ethan arrived earlier, and spent almost an hour arranging and rearranging all the tools, the wheel, carving knives, brushes, and measuring cups... He carefully lined them up like surgical instruments. He had even watched twelve instructional videos the night before, determined to get everything right. Yet somehow, he couldn't even make a simple bowl — his third attempt of the day had just exploded in the kiln (窑).

He wrote on his notebook with precision, "Attempt 3,400g stoneware, 21% water, Collapsed at 4.2cm height." Maybe the curve (弧线) was just not standard enough, Ethan thought.

Ms. Alvarez, their instructor, approached Ethan and said with a warm smile, "Beginner's tip. Don't worry about making it perfect." Ethan froze. The word "Perfect" hung in the air, sharp and cold, bringing back memories of last year's science fair — when sleepless nights and silent tears had ended not in praise, but in a crushing headache.

Around him, the others were making uneven bowls and plates with funny-looking curves. Some were even laughing at their own "disasters". No one seemed to mind getting it wrong. Ethan looked down at his own hands, still dusted with clay. Ethan forced a smile, turned to the soft clay on his table, and began kneading (揉黏土), ready for a fourth attempt.

In the dining hall of Shenzhen University, students eagerly line up for a unique delicacy: rich bowls of black-bone chicken soup. This flavorful dish traces its roots to an (innovation) AI farming project in Chishui, Guizhou, a region where black-bone chicken farming (be) a valued tradition for over 300 years. Despite its long history, the practice has faced (challenge), including disease, predator attacks, and high labor demands.

(address) these issues, Shenzhen University students partnered with the local government to develop an Al-based system. (adopt) cameras and micro-devices, this smart technology tracks each chicken's movements. When a chicken's steps fall below 1,000, the system warns farmers to check signs of illness. It also detects wild animals, helping to reduce losses from predator attacks.

After just six months, production (boost) by 30%, with over 60,000 chickens added. In appreciation, Chishui farmers gifted hundreds of chickens to the university, students turned into "Al chicken soup" for the university community, allowing everyone to enjoy the fruits of this technological achievement.

Reflecting on the project, Shenzhen University Vice President Zhang Xiaohong highlighted the (integrate) of academia, industry, research, and innovation. "Through this partnership, our students have developed practical skills, gained hands-on experience, grown into AI professionals ready to make a meaningful impact."

As a kid, I was short and1. When I played basketball, I had to put my tiny body behind the ball and throw it underhand at the hoop (篮筐). Kids laughed and called my2 style "grandma shot." I looked strange, but I3 every time. I won multiple free throw competitions using my "grandma shot", so I4 it. But my victories came with great5 — I hadn't done it the "right" way.

But did success only count if it looked the way others6? Years later, when I closed my eyes, I recalled standing on the free throw line at 10 years old,7 the noise, and focusing on the basket. My "grandma shot"8, and everyone cheered. The way I shot was odd, but it did9 the rules.

Suddenly, I realized I'd spent my life letting the "right" way10 my achievements. I was a freelancer (自由职业者) who doesn't have a stable income, and I'd always felt I was doing something11. However, I earned scholarships, built businesses, and shaped my life with12 steps. Now I know it's not the13 that matters, but the joy you find throughout the journey. There's no one right or wrong way.14, there are countless paths. There's no15 in that — sometimes, it leads to great success.

Rational thinking proves particularly valuable in certain situations. Without it, we might rely too heavily on emotions, leading to poor decisions. Studies confirm that people who think rationally tend to perform better in both academic and professional settings. Moreover, it helps individuals analyze complex problems, allow for better planning and make well-informed choices.

People who are more analytic are seen less approachable, which may make them seem distant or unfeeling. As a result, they might struggle to build close relationships or communicate warmth in social situations.

Intuitive thinking, though sometimes imperfect, shows impressive effectiveness in many everyday situations. Chess masters instantly recognize strong moves, firefighters make life-saving decisions through instinct, and artists create through sudden inspiration — none of which could be achieved through slow, step-by-step analysis. These examples remind us that intuition is not the opposite of reason.

In our modern world of constant information, the ability to use both thinking styles becomes especially valuable. Life is not a problem to be solved by logic alone, nor a feeling to be trusted blindly. In the end, to live well is to think with both the precision of a scientist and the grace of an artist — calculating when needed, but never silencing the inner voice that says, "This just feels right."
 

A. This, however, is not the whole picture.

B. It allows us to weigh evidence objectively.

C. It's experience that becomes quick and automatic.

D. Wisest decisions sing when reason and intuition harmonize.

E. Surprisingly, logical thinking promotes emotional intelligence.

F. However, sometimes intuition can be more effective than reasoning.

G. This black-and-white view overlooks the complexity of human thought.

The research began with what they see in daily life: in environments like crosswalks where people walk straight toward opposite directions, stable paths form naturally. But in spaces like airport terminals (航站楼) where people move at various angles, chaos usually wins. To understand why, mathematician Karol Bacik and his colleagues created mathematical models that study crowd movement like flowing water, looking at different walking angles and how people avoid bumping into each other. Based on these models, they predicted that when people' walking directions spread apart beyond a certain critical angle, the orderly lane formation would break down into disorder.

The research team then tested their idea in a lab-designed crosswalk. Volunteers wearing uniquely coded hats walked across a pretended intersection (十字路口) while overhead cameras tracked their movements. The team varied starting points and walking angles across hundreds of trials, mapping how crowds flowed or clashed. By analyzing thousands of crossings, the team confirmed their prediction — when the average walking direction went beyond 13 degrees, orderly lines collapse into inefficient, potentially dangerous disorder.

"This isn't just about math — it's about real-world safety," explains Bacik. "A shopping mall designed with this 13-degree rule in mind could prevent dangerous crowding, while subway stations might arrange exits to naturally guide people into efficient paths."

The implications extend beyond urban design. Emergency planners could use these findings to design better escape routes, and Al systems might better predict crowd flows in smart cities. As Bacik's team prepares to test their model in real life, one thing is clear: even in something as ordinary as walking, hidden patterns govern our behavior — and science is just beginning to understand them. Moreover, this study transforms an everyday observation into measurable facts, proving once again that mathematics can reveal order in the seeming chaos of everyday life.

Once we assign people or ourselves to a group, several psychological effects take hold. First of all, the group members assume an identity. A label is placed on them, which over time achieves a level of permanency. For example, if you decide yourself as belonging to the "I'm really not creative" group, you tend to view yourself as primarily and permanently uncreative. The longer this belief lasts, the harder it is to change.

Moreover, groups provide us with a false sense of comfort. By joining the "I'm not creative" group, we also conveniently protect ourselves from moving beyond the borders of that group into new and often unfamiliar areas. Like birds that hesitate to leave their cages even when the door is open, we eschew the desire to get out of our comfort zone—not because we can't, but because we won't. There are not just many like-minded people in the group, but it offers a safe environment to work and play.

But the problem doesn't end there. There is a tsunami of books and articles that use language such as the following: "Creative people are individuals like Leonardo, Edison, Picasso, or Einstein who have changed our culture in some important respects" and "Creative people are the ones who get ahead in their jobs, start new businesses, invent products... paint pictures, and make things of beauty." When reading these statements, we automatically assign ourselves to that "other group", knowing that we can never measure up.

However, as psychological research has convincingly demonstrated, creativity is not exclusive to a select few; it is a birthright shared by everyone. So, be mindful of what you read. Sometimes, others may be putting you in a box without your knowing.

Bees, like humans, breathe out water into the air. The more active the bees, the more wetness they put in the air. Sudden cold worsens this: each time my grandson rushed in from the snow, our heater struggled — the bees' energy rewarming forces them to release more wet air. I learned to minimize hive checks after mid-fall. Checking inside interrupts their winter preparations — closing cracks between the boxes and adjusting airflow. Now, I listen with a simple tool to listen for activity instead.

Feeding syrup (糖浆) late also backfires. Sugar syrup must be thickened to between 14% and 21% wetness. Any wetness beyond that percentage must be released into the hive as bees process their food, breathing out extra water. My solution? Ensure hives save enough honey by fall's end. I keep spare beehives in low temperature, transferring them if stores run low. Winter bees — "fat bees" packed with nutrients — handle cold better, their food processing drier.

Yet there's no universal fix. My Pacific Northwest strategies — like tipping hives slightly for water runoff — might fail elsewhere. One truth holds: bees teach patience. Every misstep (like tapping hives "just to check") carries consequences. Now, I journal successes and failures, adapting as my buzzing mentors (导师) demand.

Last winter, all five hives survived. Opening them this spring, I found lively groups — no deaths, just the steady sound of survival. Beekeeping isn't about control, but partnership. Sometimes, the wisest step is stepping back.

At one time children made May Day baskets to celebrate spring and enjoy the rewards of giving surprising gifts to their beloved ones. When I was in perhaps the third grade, our class took on such an adventure. For several days, we worked on creating paper baskets. We cut colorful stripes of construction paper and wove them together, following our teacher, Miss Anderson. We cut and wove and glued. Then we decorated them with our crayons and more cutting and gluing. Finally, we fitted paper handles onto the tops so that we could secretly hang our creations on the doors of unsuspecting receivers: surely our mothers.

We were finished right on time. Miss Anderson brought armloads of flowers for us to use in stuffing our prizes. Lilacs and tulips and al the colorful flowers of spring. We had to wait until the day was nearly over before we were allowed to choose the flowers that were just right for our baskets. I chose the biggest, most beautiful blossoms, allowing myself to be selfish for the sake of my mother. Then we fidgeted (烦躁) away what remained of our day, waiting for the clock to tick down the minutes to our release.

Finally, mercifully, the bell rang! We threw on our coats, gathered our homework and our lunch boxes, tied on our scarves and then, carefully, we cradled our offerings of love and off we ran to our individual homes! I was so excited! I ran as fast as I could down the hill, across the street, up the block, heading home. I paused at the corner of my house, to catch my breath and savor the moment. Then I glanced down to admire my offering one last time before I hung it lovingly over the doorknob. Horrors! Shock, dread and depression! My flowers were gone! Apparently, bouncing out on my mad dash home, all that was left was a sad, messed-up, wrinkled little empty basket! I stood on the doorway and burst into mournful sobbing tears.

The Beautiful Forbidden City

The Forbidden City, one of the most famous landmarks in China, (stand) at the heart of Beijing, carrying over 600 years of history. Having witnessed the reigns of 24 emperors, it has become a symbol of China's rich cultural heritage.

Visitors are often amazed by the grand halls and delicate gardens, which are designed with great accuracy (reflect) traditional Chinese culture. As they pass through the big red gates, they are immediately transported back in time. The intricate carvings and golden rooftops, which shine brilliantly under the sun, add to the palace's (glorious). Although China is home to many historical sites, few are more (impress) than the Forbidden City. It is a place ancient art and imperial power are perfectly combined, attracting millions of tourists each year. Strict rules have been applied to prevent damage from careless visitors, ensuring its charm remains well reserved future generations.

The site appears especially magical in winter, when a thin layer of snow (cover) the rooftops makes the golden bricks shine even brighter. In recent years, modern technologies (use) to protect and restore this ancient masterpiece. Thanks to these efforts, people can continue to appreciate (it) magnificence for centuries to come.

For those who love history and architecture, a visit to the Forbidden City ismust. It is not only a historical landmark but also a treasure of Chinese civilization.

We were hit by the worst stormy weather I'd ever experienced when3 Boston's Logan International Airport. The plane shook sharply. I4 the woman next to me and said, "Hey, would you mind talking with me for a few minutes? I'm really5." We hadn't spoken much during the flight6 the brief greetings. But my seatmate seemed friendly, and I suddenly felt anxious for a7 with others.

"Sure, my name is Sue Pernick." the woman replied with a warm smile. "What brings you to Boston?" I started to explain that I was on a business trip. Then the plane trembled violently, and I blurted out (脱口而出), "I might need to8 your hand." She took my hand in both of hers, patted it, and held on9. She was so10 and soothing. "This is a little bumpy, but we'll be on the ground safely soon," she told me.

On that11 flight to Boston, I almost cried12 because of Sue's firm hold, which kept me safe like a lifeline. Her gentle smile and the way she held my trembling hand will never13 from my memory. From Sue, I learned that it's OK to ask for14 from a stranger if you need it. Now whenever I am stressed or15, I just say to myself, "Just think of Sue!"

Master eye contact

Eye contact, if handled properly, can change people's opinions of you. But there's a thin line between making eye contact and staring blankly. The trick here is to maintain comfortable eye contact when you're listening or speaking.

Pick the right gestures

Our gestures can reveal our thoughts and emotions, often more accurately than our words. To command others' attention, just use simple, controlled movements such as raising an eyebrow or offering a slight nod. They convey a sense of self-confidence and sophistication(老练).

Use deliberate (刻意的) pause

I'm referring to the deliberate pause — that moment of quiet that gives weight to your, words and actions. Don't rush through your sentences in conversations. Instead, take your time, and pause at the right moments to let your message sink in.

Show active listening

Listening is a skill, and believe it or not, it shows in your body language. Are you leaning in slightly, maintaining eye contact, and nodding at appropriate moments? Or are you glancing around the room and using your phone? True class is about making others feel valued and heard by staying engaged.

A. Don't be afraid to let your true self shine.

B. One makes you look classy, the other awkward.

C. However, don't engage in overly dramatic gestures.

D. Pay attention to how you occupy and respect personal space.

E. It's not always about the words you say or the clothes you wear.

F. So next time you're in a conversation, try to be fully concentrated.

G. In the rush of conversations, we tend to forget the power of silence.

People can't bridge language gap and understand each other without iconicity. When playing a game of charades (猜字谜) , we act out our meaning, using our hands and bodies to describe the sizes and shapes of objects. The key to this process of forming new symbols is the use of iconicity. Not limited to gesturing, iconicity appears in our visual communication too. Traffic signs, food packaging, maps. . . wherever there are people communicating, you will find iconicity.

According to our research, iconicity might also exist in our voices. We organized a contest in which we invited contestants to record a set of sounds to express different meanings. The winner of the contest was determined by how well listeners could guess the intended meanings of the sounds based on a set of written options. Critically, the sounds that contestants submitted couldn't include actual words or onomatopoeias (拟声词) .

Listeners were remarkably good at interpreting the meanings of the sounds. Yet, all of the contestants and listeners were speakers of English. Thus, it was possible that listeners' success relied on some cultural knowledge that they shared with the speakers. Did the listeners also understand the speakers from completely different cultural backgrounds?

Later, an Internet survey translated into 25 different languages was carried out. Participants listened to each sound from the English speakers and guessed the meaning by choosing from six written words. Guessing accuracy for the different groups ranged from 74 percent for English speakers to 34 percent for Portuguese speakers. It is far from perfect, but well above the chance rate of eight percent expected by us.

Taken together, these studies show that our capacity for iconic communication has played a critical role. Without this special talent, language would likely never have gotten off the ground.

AI is designed to copy the human brain in decision-making and learning with the computing power to learn tasks in days or even hours. Most AI systems working in medicine employ smart algorithms (算法) and are accompanied by speech recognition and machine vision, thus helping them make their decisions more quickly and accurately when they are used in the medical field.

AI systems should learn about human medicine before they can be adapted for people in hospitals and homes. As a result, they are trained on large data sets of real-life cases. Detailed patient information in quantity is able to help fuel AI technologies, which plays a hugely important role in the success of medical AIs. One of the most important areas for AI's influencing global health is in the field of epidemiology (流行病学). Predicting disease outbreaks can save millions of lives by having resources ready if the worst happens: The company AIME has successfully combined public health data with AI to create a prediction engine able to predict epidemics months in advance with great accuracy.

Another field where medical AIs are making rapid advances is in diagnostics. AIs use pattern recognition to work through X-ray, CT and MRI images with unbelievable speed and accuracy. They have been able to do better than junior doctors and even senior specialists in some tests.

Rima Arnaout, an expert on heart disease, developed an AI that beat human doctors at correctly interpreting images by 79 percent to 92 percent. "Despite the result, as experts, we read the images and then go to see the patient," she said. "So we're both reading images and practicing medicine. I don't think that the second piece will be taken over so quickly."
