The longest heat wave on record sweeping through the town, Sebby could barely contain his excitement to cool off at the beach with Dad. Before heading out, they stopped at the nearby library to return a few books, and Sebby noticed a crew working on the roof.

"What are they doing?" he asked. Dad watched for a moment before answering. "Fixing the roof." Pulling out of the parking space, he shook his head, adding that he had worked on a roofing crew for a few years. He thought it the hardest job he had ever had — no shade, just the sun burning his neck, and a sip of cold water felt like a treasure. It was then that an idea popped into Sebby's head: to bring them some water. But the thought slipped away as quickly as the scenery flashing past his window, his attention turning to swimming.

The waves were perfect for bodyboarding, and a sea breeze cooled the air. But all too soon they were headed home, back to the heat. Sebby was half listening to the radio when the DJ gave the weather report. "The record-breaking heat will continue throughout the afternoon." Glancing at the library as they passed, he saw the roofers still at work. "Do you think they have enough water?" he asked. "I'm sure they brought plenty," Dad said, though his tone lacked confidence.

Back home, Sebby couldn't shake the thought of the roofers. He shared the idea with his brother, Marcos, who had just returned from the movies. His brother shrugged. "You don't even know those guys. They've probably gone home already anyway."

Thinking Marcos may be right, Sebby walked to the driveway for a clearer view: the roofers were still there. "I don't see any coolers or bottles anywhere," he told Dad. "I really think they need some water." A look of concern came over Dad's face. He stood and picked up his car keys. "I think you're right. It's only going to get hotter."

Jiuzhaigou Valley, a UNESCO World Heritage Site, is a place of breathtaking beauty that seems to belong to another world. Located in the mountains of Sichuan Province, this valley, with its world-famous reputation, (witness) millions of visitors each year to a journey of a fairyland on earth.

The valley is named after the nine Tibetan villages (dot) throughout its area with its most iconic features — the multicolored lakes, crystal-clear water reflects the surrounding forests and sky in astonishing colors of emerald (翡翠).

Walking along the wooden plank (板条) paths, people feel as if they are stepping into living painting, where the air is fresh, and the silence is broken only by the sound of water (flow) or birds singing in the ancient trees. It is this    (harmony) combination of elements that makes Jiuzhaigou so unique.

However, a major earthquake causing significant damages happened in 2017, leading to a series of geological changes and the temporary (close) of the park. Since then, greater efforts (make) to restore its natural beauty and stricter tourist management policies have been carried out, like limiting the number of daily visitors to minimize human impact effectively.

Today, Jiuzhaigou stands a powerful model of nature's resilience and conservation, reminding us that we are not the owners of such wonders, their guardians. Preserving its splendor for future generations is a responsibility we all share.

I agreed with a reluctant sigh, perceiving it as totally   2.But as I watched father's hands work, something shifted. As he explained the   3 of each gear (齿轮) and the clock's history, his eyes   4 with a passion I had never noticed before.

We worked together for weeks. Slowly, the clock   5 its former elegance and charm, while I learned to wipe the delicate hands and gently   6 the glass. My impatience   7 fascination: I wasn't just cleaning; I was   8 a piece of family history.

The day we hung the clock was a day of pride. Its steady tick felt like a heartbeat. That experience taught me a   9 lesson. It wasn't about the clock, but the time spent with my father. I came to   10 the value of his wisdom and skills I had once   11.

Now every time I visit home, I check the clock and   12 it. It works not only as a beautiful artifact (手工艺品) but also as a   13 of the day I truly saw my father. His workshop was a shelter where patience and love could   14 anything broken. He would say, "Some things, like this clock and our bond, just need a little   15 to run forever."

With huge amounts of information at our fingertips in the social media-fueled Internet age, we are in theory better equipped to travel more and better. But for this Malta trip, we decided to do something different. We'd build the trip by talking to random locals. No guidebook allowed. No smartphone either — unless we were completely lost.

Approaching locals for travel tips can be awkward. So I came up with a trick: a deck of cards with common holiday questions. Locals would draw a card and give a tip based on it. We'd follow the tip, then ask them to recommend another local to help us.

How did it go? Philip, wonderful and friendly, introduced us to almost the whole island. When asked about his "favourite lunch spot", he drew the card and recommended Claire, who runs Mojo restaurant in Victoria. For the "favourite cafe" card, Claire suggested Gleneagles in Mgarr Harbour. It's run by approachable Tony-a goldmine for tips and stories.

Tony, a silver-haired man with a rough voice, was one such local. He told stories of his coffee shop's 40 years, full of emotions and old regulars. His words made those times almost tangible, making him a living connection to Gozo's past.

My message is simple. If you visit Malta, leave your guidebook and phone in your room. Go to a cafe, order a local drink, chat randomly with a local. It grows meaningful and exciting when we connect with locals. We learn their stories, and maybe gain a new perspective.

A. Our experiment started in Gozo with a local restaurant owner.

B. Malta has been known for its coastal scenery and ancient ruins.

C. At its core, travel revolves around genuine human connections.

D. There's no time machine, but some locals connect you to the past.

E. As a natural icebreaker, these cards served to reduce the awkwardness.

F. We visited many famous attractions recommended by travelers in Gozo.

G. Instead of overplanning with blogs, Instagram or guidebooks, we chose chance.

The idea of chronotherapy — giving drugs at right times — owes much to traditional Chinese medicine (TCM), which describes organs' activity peaks at specific times. French researcher Francis Lévi drew on this wisdom to explore cancer treatment: healthy cells divide fixedly, while cancer cells multiply uncontrollably. Since chemotherapy (化疗) targets rapidly dividing cells, Levi reasoned that giving drugs when healthy cells are "asleep" could boost effectiveness and reduce side effects.

Medical tests proved promising. Those who received chemotherapy at 6 am instead of 6 pm experienced far milder sickness and tiredness. Similar benefits emerged elsewhere: afternoon heart surgery is safer, and flu vaccines given between 9-11 am generate four times more antibodies than later in the day.

Yet chronotherapy faced a problem: everyone's internal clock varies by up to 12 hours. Measuring it used to be time-consuming — tracking melatonin (褪黑素) release required hours in darkness and frequent samples. Now, new tests using blood or even hair offer quicker results. For example, Germany's BodlyClock test analyzes clock gene activity in hair follicles (毛囊) to reveal internal time, helping tailor treatments.

These advances in determining our biological time not only support precision medicine but also the use of daily rhythms to enhance overall health. For instance, exposure to morning light helps advance the body clock, while minimizing evening blue light promotes sound sleep. Scheduling demanding mental tasks or intense exercise during personal peak cognitive and physical periods (typically afternoon to early evening) can boost performance.

By making use of our circadian rhythm - through timed treatments and rhythm - aware living - we can unlock longer, healthier lives.

Within ordinary urban landscapes, life displays extraordinary toughness and creativity. Plants and microorganisms not only survive but grow well in the heat and pollution of city gutters. Urban animals have also developed smart behaviors: Japanese crows use cars to crack nuts, and Australian cockatoos open trash bins for food. Furthermore, cities drive physical changes in their residents. Some lizards have developed stickier feet to better hold on smooth man-made surfaces. This concrete "jungle" is thus not a biological desert but a dynamic, human-made ecosystem, representing a fascinating new chapter in the story of life on our planet.

Therefore, the old image of a naturalist — a professional in remote wilds — is outdated. Academic papers and online courses make biology and ecology procurable to everyone. Community labs and nature clubs enable ordinary people to do research with microscopes and other simple tools. When we accept the city as a real ecosystem, we allow everyone to become a "community scientist".

For those feeling disconnected from nature in cities, there's a new way: just stay curious and notice the ignored ecological corners, and city life may be filled with new surprises and joys. You don't need to be a professional scientist — anyone can be a naturalist-explorer in the urban wilderness.

While initially desiring to become a physical therapist (治疗师), he found himself particularly drawn to education through his mother and stepfather, both seasoned educators on Long Island. After completing his specialized training at SUNY Cortland, he enthusiastically joined this school in 2021, valuing the opportunity to work with young students. Rather than conducting standardized drills, he uses multi-sensory strategies: pairing verbal instructions for pushups with visual step cards, and using soft foam (泡沫) balls to help those with motor skill challenges feel successful. For students uninterested in movement, he leans into their strengths — like creating a "rhythm jump-rope" activity for a music-loving student who dislikes team sports.

Nathaniel Marner, the school principal, described Dennehy as a "forward-thinking educator who constantly invents creative ways to engage students." This impact is perhaps best illustrated by the genuine feedback from his students. Fourth-grader Lopez also showed her ultimate approval, "He's cool." She further explained more about his appealing personality and the diverse activities he has introduced, from basic exercises to various sports.

Beyond the school's walls, Dennehy extends his educational impact through coaching the junior volleyball team and instructing student participation in regional fitness programs. Yet his most rewarding professional moment remains fundamentally simple: surveying his gymnasium to witness his students actively engaged, each face reflecting the genuine joy of movement — a proof to his success in making physical education an accessible source of confidence and well-being.

Like parks around the world, those in our region are feeling the impacts of climate change. As a registered nonprofit based in San Francisco, the Parks Conservancy is working in collaboration with the Presidio Trust and the National Park Service to help these parks — and the communities that depend on them — build resilience (韧性) against the backdrop of rapid environmental shifts. We also aim to increase understanding of climate-related threats to our parks, our local communities, and the planet, while driving meaningful action to address them.

This work looks a lot of ways, and often connects across multiple programs, projects, and park boundaries. It's all done in partnership with agencies, community partners, and community members, and reflects the need to address climate change at different scales.

In the morning，I write this to-do list：

⒈Go to the bank.

⒉Get a nice haircut.

⒊Pick up my academic statement from college.

⒋Submit my poems.

I think， "That's enough for one day."

Up until a few years ago，I didn't aim to be anywhere.And in order to be nowhere，one does not need a to-do list as a guide.Focusing only on the most pressing matter in front of me was enough.Let the next urgent moment think for me.

My mother had tried to teach me about planning my day ever since I was 10.But I never practiced it until I was 25 and done with college.That's when I awoke to the fact that I didn't want to waste any more time.I live in Nigeria，where life and success can be difficult.There seem to be many roads to failure here.

I grew up seeing my mother firmly in charge of her day.She knew—and still knows—where she needed to be at every moment，in every detail.She may not be good at singing，acting，or sports.But she is excellent at planning.Every day she writes a list.I never understood why she had to write down a list that consists of items you can easily hold in your mind."Your to-do list is like your second mind，"she told my younger self."If you ever feel lost or overwhelmed，you consult your second mind."

I didn't understand what she meant by"a second mind"until I seemed to lose my first mind in my everyday life.Sometimes，it seems as though it's the rainy season in my mind，flooded with confused and distracting thoughts that lead nowhere.I need a second mind—now!

As I sit in the barbershop awaiting my nice haircut，a friend asks me， "What's next？"

"Pick up my academic statement from college，"I say."Then submit my poems."

"You've got it figured out like a granny，"he jokes.

"No，"I say， "like my mother."

Science serves as a powerful tool for unlocking the mysteries of the universe，but understanding its limitations is essential for its effective application.There are occasions where I have used the handle of a knife as a hammer（锤子），but the result would have been better if I' d had a more suitable tool at hand.As far as science goes，it is really good at testing things that are testable，but not so for those that are not.

We can do，and have done，an impressive amount with our brains.But there are limits.Sometimes these limits go away if we keep at it for long enough—we just need better facilities and experiments to get the answer.Breaking new ground in modern science this way can be costly.Next-generation supercomputers or incredibly large telescopes are expensive，yet these may be required to find answers to some of the unsolved mysteries of the universe.

Sometimes the limits we encounter in trying to unlock the nature of the universe are cognitive（认知的）.Think about this：human DNA is only about 1.2 percent different from that of chimps（黑猩猩）.Chimps are smart，no question.But could you teach them advanced mathematics？What if our DNA were another 1.2 percent further evolved than it is？What might our brains be capable of then？The level of abstract thinking might be un-imaginable.

Sometimes the limits we hit are fundamental.There are laws of nature we may never be able to understand，however advanced our brains might be-come.There are experiments we might never be able to perform.We may never be able to test what caused the universe to be created，and what caused the cause of the universe being created.This is where science may never break through.

For something to be considered scientific，it must，by definition，be testable.There is a problem here：it may not need to be testable right now，but it must be testable at some point in the future by experiment.If an idea is untestable，that doesn't mean it is wrong.It means it is untestable for now.These untestable ideas also happen to be some of the most interesting ones，probably because they' ve puzzled humanity for centuries.

All animals take in oxygen from the air they breathe in，and release CO2 from their blood when breathing out.Most mammals（哺乳动物） can't directly detect oxygen levels in the blood supplied to their tissues.Instead，they rely on the rising level of CO2 in their blood to signal that they might need to take a breath.But a recent study published in Science suggests seals（海豹） can sense the amount of oxygen in the blood，and change their diving behavior in response.

To find out if oxygen levels affected seal behavior，Professor McKnight at the University of St.Andrews and his colleagues created a special section in a pool where young seals were held.In one corner，there was a breathing chamber（呼吸室），where they were sheltered from the rain and the wind.

The breathing chamber was surrounded by panels that prevented surface swimming，yet swimming below the surface for about 200 feet would give the seals access to a feeder where they could eat as much fish as they liked.Once the seals got familiar with the setup，the researchers started to gradually change the composition of the air in the breathing chamber，in-creasing or reducing the levels of oxygen and CO2 to see an effect on their behavior.Sure enough：the higher the level of oxygen，the longer the seals stayed at the feeder.

The finding suggests that seals don't just physically respond to oxygen levels by changing their heart rate or breathing，but that they are sufficiently aware of them to change their behavior.This ability would put seals in a class beyond any land mammals that have been tested.Since oxygen levels on land remain stable，humans don't seem to have evolved（演化） to notice low blood oxygen levels，sometimes not even when they're about to pass out in free-diving.

Therefore，in free-diving without oxygen tanks，accidents are quite common.Our reliance on sensing CO2 levels in our blood instead of oxygen may be to blame.Actually，this is a perfectly reasonable strategy on land，where growing CO2 tends to signal breathing issues.But when holding our breath during diving，relying on CO2 levels is risky，especially on repeated dives.Because every time we surface and breathe in，our sensitivity to CO2 is decreased，even if its levels are already high，and this increases the chance that a person will，without awareness，pass out before they get to the surface.

My great grandmother received the dollhouse（玩具小屋） from a family friend back in the late 1800s.It was then passed down from generation to generation.I was seven when I discovered it under-neath the tree on Christmas morning.

In our house，Mom set up a sewing area.I sat at her sewing machine，my feet barely reaching the presser foot.Mom bent over me，her hands on mine，gently guiding small bits of cloth under the needle to create dollhouse bedding.She also taught me to make mini-blankets.With a little paint and glue，Mom demonstrated that anything could be turned into dollhouse furniture.I learnt to view the world as a place of possibility.I spent hours of my girlhood sitting before my dollhouse，telling made-up stories，and creating miniatures（缩微模型）.But eventually school activities took over，and the dollhouse was moved to the attic（阁楼）.

Over the next 40 years，the storytelling skills I'd practiced with the dollhouse grew into novel writing skills，and I developed a career as an author.One day，after hours of working on my fourth book，I took a break by surfing the Internet and happened to notice the beautiful dollhouses people posted on social media.They reminded me of mine.I went to the attic，brought it back to my room and started updating it.

During the mindless hours of sewing and furnishing（布置家具），I listened to audiobooks about the history of dollhouses，learning that they were not invented for play.There's a long，rich history of people in hardship turning to dollhouses to find comfort.They weren't produced as toys until mass production became standard after 1945.This inspired me to create a novel where art saves the day.

The truth was I myself needed art to save the day.Mom was then slip-passing away from me owing to progressive memory loss.The only topic we could discuss with any genuine joy was the update of the dollhouse.She loved retelling its history—those old memories.Mom didn't find it strange at all that her 50-year-old daughter was updating the dollhouse.She just thought it fun and beautiful.And it was.It was a world where Mom and I were at our best together.

Life is a road full of minor inconveniences and major setbacks，which everyone faces，

1 wealth or social rank. That is why optimism，the ability to see the 2 side of every negative situation，is key to success.

What made optimism so meaningful to me was when I 3 the A team of the basketball club for the upcoming season. I had always been the starting point guard，and my4 on the A team was something I took for granted. However，I only made the B team，5 I worked my hardest. I didn't understand why until I saw the new A team，crowded with players that all6 me. 

I had to give the B team a chance. But to my7 ，the play level was much lower than what I was used to. I lost the drive I'd had before and gradually became8 . 

One day I came across a social media post of another basketball team，whose point guard was much more9 than her teammates. When her team-mates made multiple mistakes10 ，which cost them several points，I expected her to be upset，but11 ，she patted her teammates on the back and comforted them. As I watched her more，I noticed that she led her team，always 12 and uplifting her teammates. 

The realization hit me like lightning. What I thought was a13 turned out to be a valuable opportunity，presenting a rare chance to develop14 . So，I started using my15 to be a leader for my team. When our coach needed a（n）16 ，I was the first to raise my hand. When my teammates needed help with a skill，I 17 taught them over and over again. My effort paid off as I18 remarkably not just as a player，but as a person—some-thing I could have never achieved on the A team. 

When facing challenges in life，some people19 them with optimism，while others tend to complain. Optimism is a palette（调色板），with which you can paint your own light in the darkness，shelter in a storm，and most importantly，a better20 of yourself!
