I would pull them out,4 my little arms till deep into the cracks of the sofa, hoping to find some spare change that had5 out of someone's pockets. Often to my6, I would find a dime or a quarter. Then I would run off to the pool happily.

It's only recently, however, that I realized I found7 there an awful lot during the summertime. I8 looking between the cushions in the winter a few times, yet9 to find a penny. Although I never saw them, I think Mom and Dad would10 change down there for me to find. They did so knowing it would make my11 and bring a smile to my face. Of course, they never said a word even after I had12. I guess some13 are too good to share.

I think that maybe an unseen act of14 has a special joy to it. You get no appreciation or thanks for it, at least not to your face. Yet, it fills your heart with happiness. You know that you are helping another, making someone's life better and this world a more15 place.

When you notice specific distractions, you can block them out. Take note of this specific distraction and then tell yourself you are going to overcome it. The next time you see it happen, remind yourself not to look. Keep doing this every time the distraction comes up, and eventually you will no longer notice it.

Life can get really busy, so it's no surprise if you find yourself distracted from studying by thoughts about everything else. Rather than acting like all of those other needs don't exist, why not give yourself an outlet? Spend 5 minutes thinking about everything that's on your plate, but then tell yourself it's time to focus on the main task for now: studying.

Prioritize your studying by setting a main goal. For example, if you have a biology exam coming up that covers three chapters, you don't have to cram everything into one study session. Breaking things down and establishing just one primary aim will make your study plan more manageable.

Go off the network. Texting, social media, calls, and other distractions that come from our electronic devices are some of the biggest barriers to staying focused when studying.

If you do these consistently, you should find that you gradually spend less and less time being distracted.

A. Set a study schedule.

B. To be distracted is common.

C. You should give yourself a worry break.

D. Try focusing first on the parts that give you trouble.

E. Luckily, the fix is easy and totally within your control — unplug yourself!

F. If you keep your phone in another room, you're less likely to use it while studying.

G. Say you're trying to study in the library and you keep getting distracted by someone texting.

The young man found himself dissatisfied with his social life — busy yet unfulfilled, and he built his friend list to diagnose why. He found that he had a small group of first-tier friends and a huge number of acquaintances. But the friends who caused him the most burden and stress were those in the middle ranks. Call them the "medium friends".

R. told me about a certain friend. They were close during college but by their 30s, R. simply did not feel as connected to her as he once did. When this friend recently reached out for his support, his initial reaction was annoyance, followed by guilt. But she was pressing him in a way that felt too heavy, given what their friendship had become. He wrestled but did nothing. Emily Langan, a communication professor who studies friendship, described this as feeling guilty for not being more involved because they were just not that kind of friend.

Medium friends are genuine friends who share history or interests. They make you laugh or offer insights. But, unlike the closest friends, medium friends test the limits of your time, love and energy. There are so many dinners in a week, and so many people with whom you can be constantly texting. Medium friends prove it impossible to be all things to all people. And that is the problem with medium friends, the invisible lines you draw around them without ever being clarified — to them or even, possibly, to yourself.

Mutual sharing and caring in a context of trust is the foundation of every friendship. The tension in medium friendship is this absence of clarity, allowing for the possibility of what Claude Fischer, a sociologist, referred to in an interview as "asymmetric expectation": You may like your medium friend less (or more) than they like you.

Turbulent flow occurs in fluids like ocean currents and storm clouds, where big swirls break into smaller ones. "These swirls aren't random. They arrange themselves in specific patterns that can be predicted by physical laws," explained Yongxiang Huang, lead author of the study.

Huang and his colleagues examined 14 main whirling shapes in a digital version of the painting. The atmospheric motion in the painted sky cannot be directly measured, so they measured the size of brushstrokes and the brightness of varying paint colors. They discovered that the 14 big swirls match a physical law called Kolmogorov's theory of turbulence. The smallest paint mixes also follow a pattern known as Batchelor's scaling.

Finding both laws in one painting is rare, and it is such an amazing coincidence (巧合). Van Gogh would not have been aware it was physics, but likely he spent a lot of time observing turbulence in nature. "It must be planted into his mind so that he could make this famous painting so convincing," Huang said.

The team performed a similar analysis and detected the same phenomenon in another painting, Chain Pier, Brighton by John Constable in 1826. While it doesn't have clear swirls, its clouds show rich structures like those seen in the sky.

Scientists have long struggled to fully understand turbulent flow, which is important for weather forecasting, flight turbulence and many other processes. Even after over 100 years of study, defining this complex natural phenomenon is still challenging. Huang also noted that artworks like The Starry Night matching turbulence models might mean the statistical methods and tools are less precise than thought.

It was my first experience of being led through challenging books with an expert guide. Every few pages, Mom would stop and ask me questions that challenged my thinking about the text, drew me deeper into its themes and created a space to ask my own questions. And this is how I came to love reading — and came to be a professor of classic literature.

Most of my students who hate reading don't have mothers like mine. And one-to-one tutorial is impossible in my mid-sized university. But recently, in a conversation with a friend about ways AI might make museums dynamic and interactive, I thought about books. What if AI-enabled chat windows could be introduced in a text and offer a site of real-time conversation about it with someone as smart as my mom?

Then I started creating Rebind, an e-reading platform. I dictated 30 hours of answers to nearly 1,200 questions about Thoreau's Walden and asked another 1,000 reader-interesting questions. The work was dull: just me talking into my recorder. Then it struck me that being interviewed about the book might make it pleasant, meaningful and, most importantly, dynamic. So I invited Michael Goodwin, a Thoreau expert, to ask me questions. It worked. Michael, playing an inquisitive student, drew out insights I didn't even know I had.

This led to a key idea: if AI platforms use real conversations, about meaningful subjects, as their training ground, users are more likely to have rich, simulated (模拟的) conversations about such subjects. I tested this by interviewing the prizewinner John Banville about James Joyce's Dubliners, and the results were remarkable. The conversations in the e-reader sounded like, and reacted like, the conversations between Banville and myself.

I'd like everyone to love reading and use AI in ways that aren't meaningless or disappointing. In my heart, like my mother, I'm a teacher, and I believe this is one of the great teachable moments of our time.

Around 160 experts attended the International Forum on Cave Temple Conservation in Chongqing August 19 to 21 to explore opportunities for cooperation and methods to protect rock carvings in cave temples around the world.

The carvings run the risk of damage over time as a result of weathering and climate change. Li Qun, director of the National Cultural Heritage Administration,(say) in the opening ceremony that Chinese cave temples displayed remarkable characteristics in terms of their subject matter, and artistic style, which reflected the(peace) nature of Chinese civilization.

The Chongqing forum was held to improve the preservation of cave temples and uncover their value and historical significance,(contribute) to the preservation of humanity's intellectual achievements.

Experts agreed(promote) the protection of cave temples in light of global climate change, develop new materials, build early warning systems, and create a global database of historical images, they hope would help future generations appreciate their beauty.

"Water and wind are the primary factors causing damage to the cave temples and stone carvings(global)," said an expert, adding that climate change had led to the increasing uncertainty(cause) by natural threats. He called for in-depth(study) on core factors such as water-related damage and the geological environment. Moreover, efforts should be directed toward strengthening archaeological investigations exploring the values of these sites, as well as managing tourism.

Experts have found more evidence of the harm caused by disturbing our body clocks, linking it to depression and mental disorder. It's a warning to our body's natural rhythms, which influence our sleep as well as a range of other processes in our body. Here are the things we can do for a good night's sleep.

●Limit evening light. Are you inseparable from your mobile phone? Do you check your social media late into the night? These devices produce powerful blue light that is particularly bad for our sleep. Having a cut-off time for stopping using these devices of an hour and a half before bed is ideal. We should also limit other forms of electric light after sunset.

● A glass or two of wine, or a sip or two of brandy, for many is a pre-bed routine. But despite what you might think, experts say that a glass of wine before bedtime actually doesn't improve our sleep. Alcohol has a strange effect in that it makes it easier to fall asleep, but it makes it harder to stay asleep and it affects the quality of our sleep.

●Be consistent. It may be tempting to stay up late on Friday or Saturday.This helps to reduce social mismatch between when we sleep during the working week compared with the weekend. The bigger the social mismatch, the more harmful it is for health.

●Have a pre-bed routine. Having a pre-bed routine helps signal to our bodies that it's time for sleep. Activities such as reading a book or having a bath can help to mentally relax and get us ready for bed. Parents do this with their child to get good sleep. They have a set routine where they feed, bath their children and put them into bed.

●Make your bedroom a place of rest. Easily portable computers and phones have transformed our bedrooms from sanctuaries (保护区) of rest into places of entertainment. But if we want to boost our chances of a good night's rest, we need to reclaim them for sleep. Keeping your bedroom cool is also important because it's easier for our bodies to sleep in colder temperatures.

A. Avoid a night wine.

B. Get a good night's sleep.

C. If so, you're likely to be disturbing your sleep.

D. There's nothing around them and then they read them a story.

E. To do this we should keep phones and computers in other rooms.

F. Our body clocks are designed to follow the rise and fall of our sleep.

G. However, ideally we should go to bed at similar times throughout the week.

The robots, which look like electric rice cookers with wheels, were part of a pilot program last year by Starship Technologies focused on delivering meals from local restaurants in dozens of cities around the world.

This week, the company revealed plans to broaden it's delivery service beyond food to include packages, a move that made it "the world's first robot package delivery service". The package delivery service is only available in some cities in the US.

The wheeled robots have a top speed of 4 mph and and can detect barriers from as far as 30 feet away. "The robot can operate through just about anything," says Nick Handrick, head of operations for Starship's D. C. office, "If you have something in the way, it's able to climb it." By giving customers control of when deliveries occur, Starship Technologies is promoting its service as a way to combat package theft.

To sign up for the service, which costs a little more than $10 per month, customers need to download the company's app. Customers then create a "Starship Delivery Address," a unique address inside a Starship facility, instead of a home address, where they can have packages sent from places such as Amazon. com.

Once a package is delivered to the Starship address, customers receive a text notice that allows them to schedule a home delivery via robot. The robots are opened by customers with a mobile phone code (代码).

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out (持久的) increases in blood pressure can cause long-term health issues. So, planning to sit for a long period of time? Don't keep your legs crossed.

Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle . While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

When I got older and started going to school, we couldn't watch our game shows regularly. That was okay with me, though, because the one thing I liked better than watching game shows with my grandmother was helping her bake. Watching her in the kitchen was amazing: she never seemed to need the recipes but everything she made tasted delicious.

At first I would just sit in the kitchen and watch, even though I didn't understand what she was doing. As I got older, she let me help with the easy parts, such as measuring the sugar. The day she let me separate the eggs, I felt like I had found complete pleasure.

At last, my parents decided that I could take care of myself, and my grandmother stopped coming over every day. The love of baking, however, stayed with me. I started baking by myself, and even if the cookies ended up burnt sometimes, more often they turned out pretty well. I tried out new recipes, and whenever I got to a thorny part, I would call my grandmother for advice. Sometimes I would call her just to talk, too. I felt like I could talk to her about anything.

My grandmother passed away ten years ago, but I still think of her every day. Last week, I found a recipe book she made for me. It included her recipes for brownies, cookies, and my favorite, lemon pie. As I looked through the pages, I thought I could hear her voice. She was the one who taught me not just about baking, but about life.

When entering seventh grade, I was excited about many new things, but one thing really bothered me — I started getting acne (长青春痘). Initially, it was just a little, but then, it seemed like overnight, my face was covered with it. I tried to hide it with my hair, but it just wouldn't work.

I was consumed with worry that my peers would make fun of me. I couldn't concentrate in class, as my mind was constantly preoccupied with my appearance, causing my grades to slip sharply. I started to feel inferior (自卑的) to my classmates and even avoid interaction with them. I tried to get rid of the acne. I washed my face multiple times a day, using all sorts of acne creams I found. I also avoided snacks that might cause it. But all ended up in vain.

One day, our school announced a sports day and the teacher asked us to form our own teams. As a sports enthusiast, I had been eagerly expecting it, but I was scared that no one would join me because of how I looked. Standing in front of the mirror, I kept imagining how my classmates would react when I asked them to team up with me. The fear of rejection held me back from approaching them.

But then, Kim came to me, "Do you want to join us for the relay race? I've seen you run before and you've got the speed. If you join us, we'll have a good chance to win." In disbelief, I managed to utter "Yes," still feeling self-conscious but also incredibly grateful.

I, together with another three classmates, signed up for the relay race. We trained for it and discussed strategies together, none paying attention to my acne. Because of my advantage in speed, I was even assigned to run the last leg, which was the most crucial part.

A red panda moves along the branch of an evergreen tree, placing one front paw (前爪) in front of other like a gymnast on a balance beam (平衡木). Despite its name, the red panda is not (close) related to the giant panda but (share) similar habitats and a diet primarily consisting of bamboo (leaf) and shoots. While giant pandas spend most time walking around on the ground looking for food, red pandas spend about 90 percent of their time in the trees. In fact, red pandas have adapted so well life in the trees that they're famous for their incredible balancing skills. They even have a special wrist bone that helps when climbing. Spending time in trees is these animals avoid enemies, such as snow leopards. Their reddish coats and white face markings provide cover in the red-brown and white trees where they live.

However, red pandas are endangered, as their forest homes are being cut down their fur as well as their adorableness might put them in more danger. China has taken significant steps (protect) this rare species, such as establishing nature reserves, and (promote) sustainable land management practices. Some organizations are using high-tech methods to track poachers (偷猎者), like taking a DNA sample from a red panda (rescue) from the illegal trade market.

The consequence is imaginable - my sleep quality3 as I stayed up late, scrolling (滚屏) through endless feeds. Worse still, my classmates were engaging in meaningful activities and making progress while I was merely using up my previous advantages and became4. This contrast5 my self-criticism. So in January, I decided it was time for a6 .

I7 my social media exposure by consciously redirecting my focus to other fulfilling activities. Rather than mindlessly scrolling through my phone, I8 reading and physical workout. I also packed the phone away before bedtime, allowing my mind for a9 night's sleep.

But staying on track is10, especially in an age when a smartphone is a necessity. Sometimes, I just couldn't11 the constant stream of notifications, which led me to scroll before bedtime once again. However, I must admit that change is a process and failure is one of the steps to make12.

Now my mind and body are already thanking me. My spirits have13 risen. Besides, I've lost 12 pounds and worked with higher14. I know I still have a long way to go, but I feel proud as I am becoming a better me with a sense of15 in life.

Using tools of various types to create helps build delicate skills. When first learning how to sew, knit, woodwork, bake and so on, one must learn how to use the tools safely and correctly. Moreover, learning how to follow a pattern to obtain the desired result is an important skill as well. But that's not all. .

Once basic skills are developed, there is a great deal of opportunity for creativity. Children can come up with their own plans and patterns. They can experiment with different stitches (针法), materials, designs, etc. Creative thinking is also highly valued in many workplaces today. While making something by hand takes time, sticking with it develops both patience and persistence. Additionally, handwork can be a break from our technologically driven world. Creating something both beautiful and useful is worthwhile.

You can start by teaching your children something you enjoyed and learning together with your children. Handwork can be positive to your family life!

A. This is understandable.

B. We all enjoy the thrill of saying, "I made that! "

C. Some children are naturally drawn to arts and crafts.

D. Finally, you will develop the ability to do handwork.

E. However, handwork is essential to children's development.

F. It also increases mathematical understanding as items must often be measured.

G. With all these benefits, it is easy to see that learning handwork is a valuable activity.

This space-to-ground experiment began with 6 rice seeds sent into orbit in 2022 on the Wentian spacecraft. Taikonauts onboard Tiangong bred these seeds into 59, which they returned to Earth. Researchers then selected high-quality seeds, growing them under controlled climate conditions and producing around 10,000 new seeds.

Zheng Huiqiong, a lead researcher at the Chinese Academy of Sciences' Center, shared that the team's findings suggest space-bred seeds can reproduce effectively on Earth, suggesting potential for future space agriculture. Zheng highlighted that the space-bred rice possesses unique traits, such as a higher sugar content, with sugar levels estimated to be five to six times higher than standard rice. The space-bred rice also showed a slight increase in protein content. "That means space-bred rice tastes sweeter and has more energy," she added.

Space breeding, the method used in this experiment, exposes seeds to space radiation and microgravity, generating gene mutations (基因突变). These mutations are carefully assessed upon the seeds' return to Earth, sometimes resulting in advantageous traits like shorter growth times, improved disease resistance, and higher output. Zhao Hui, an expert in China Academy of Space Technology, emphasized the safety of space-bred food, explaining that unlike genetically modified crops, space-bred seeds naturally mutate without introducing foreign genes. However, the space-bred rice has fewer leaves, which complicates close planting. Researchers are planning further studies to understand these leaf traits and explore possible genetic changes.

The Tiangong rice experiment marked a milestone for crop science, as it was the first time that rice had completed a full life cycle — from seed germination (发芽) to reproduction — in orbit.

Yi Luo at East China Normal University and her colleagues employed 47 volunteers — roughly half liked spicy foods and half didn't — to receive drops of both mild and strong hot sauce in their mouths while lying inside a brain imaging scanner. Computer controlled the liquids sent out not-so-spicy and very spicy sauce, as well as water to clean their mouths, through a bunch of three really long tubes that went right into the participants' mouths. The researchers conducted one round of experiments without setting expectations. But in the second run, they signaled to participants what intensity hot sauce they would get using different-coloured shapes. An image of two red peppers, for example, signaled the hottest sauce, while one red and one blue pepper signaled the mildest.

The brain scans showed that, for hot haters, the negative expectation of receiving a spicy sample enlarged activity in brain regions that process pain. This provides a "critical warning" for how medical patients' negative expectations could increase pain, says Luana Colloca at the University of Maryland. By comparison, the positive expectation of receiving a spicy treat boosted a pleasure signature in the brain of hot sauce lovers, but only for the mild version. This represents "parallel subjective realities", a theory on how expectations shape subjective experiences and perceptions of reality.

"Future studies could investigate how strongly such brain patterns track subjective experiences of pain or pleasure," says Tor Wager at Dartmouth College in New Hampshire. "The broader implications are beyond spicy food," says Yi Luo. "Understanding how positive and negative expectations influence understanding can inform approaches in medicine. "

I took the one less traveled by,

And that has made all the difference. "

As Robert Frost reminded us, choices are often difficult and will bring both a gain and a loss. Should I spend my Sunday playing golf or taking a day trip to the North Fork with my wife?

If you are a golfer as I am, you will say "Certainly, go playing golf. " Golf is perhaps the greatest challenge to self-improvement. In golf, every swing is counted and can easily be recalled and reviewed by the golfers as they lie in bed that evening, and therefore, self-improvement is pursued.

Now let us return to the question at hand. You will not be surprised to hear that I did in fact go to the North Fork. But, how has that improved me? Can this be quantified (量化)? In golf, whose goal is to complete the game with as few shots as possible, if I average 80 and I shoot a 76, I know that for that day at least I have improved upon my former self and thus feel satisfied.

You may argue that travel is not about self-improvement at all but just about having grand experiences. I beg to differ. It does matter how these things change and improve me. Seeing the folks dancing in the streets should change you. And talking to the manager of the biscuit shop, ought to change you. I think travel does change us, but it's very hard to say just how. How does one quantify buying a peach at a farm? Or how do you quantify the tasty taste of the scones (司康饼) at a stand?

Reviewers have had a hard time analyzing the meaning of Robert Frost's poem. To be honest, I would say all of us have a hard time analyzing our wish to travel to faraway places. I am not sure what the answer is to this tricky question. I may not have made any hole-in-ones on the North Fork but I did enjoy those scones.
