In order to "reduce the carbon footprint" Stewart planned to produce enough solar energy to1 his school's science labs. Now his plan is2 to happen. The installation of 30 solar panels is3 for late November.

As he began his research on solar4, he discovered a useful phone app. By entering an address, he could5 how much sunlight the6 receives each day.

7 how much sunlight it receives, Stewart found that his school building was the8 location.

Suggested by his science teacher, Debbie Wheeler, Parker first9 an energy audit (测算) of the science lab to see how much energy a10 lab uses per day.

Then, he started his research and11 the head of his school to fund him. Now the project has grown to12 a total of 30 panels. They are13 to generate enough energy to run all four of the science labs on14.

"It feels surreal (犹如梦幻的) to think that an idea I had stemming from my AP Environmental class would have this kind of15," said Stewart, expressing16 for Wheeler's help. Wheeler said the success of the project was17 Parker's efforts and willingness to follow through on the18 from start to finish.

"I've had other students talk about environmental initiatives on campus, but Parker had the19 and tenacity to make it happen," she said.

Parker said he would ultimately like to study20 engineering at Stanford University in California.

Quiet people think before they speak. In a work discussion with colleagues, the quiet men and women hardly speak suddenly, and instead, they listen carefully. With less time spent talking, quiet people have time to really think before they speak. Because they are so selective with words, when they speak, it seems like the whole world stops to listen to what they have to say.

. With their quiet, relaxed temperament (性情), quiet people are often the ears that others run to for advice, and are also respected for their good listening skills and cautious words. Additionally, quiet people rarely annoy others in their presence and they often make others feel at ease.

Quiet people work on a more productive basis. Quiet people tend to be free from the distractions (分心的事) that often come from being around people all day long.. It is common to observe a quiet co-worker, alone in his or her office for hours at a time working on the quiet focus.

A. Quiet people know how to listen.

B. Quiet people seem easy to get along with.

C. It is rare to see a quiet friend speak rudely.

D. So they are able to accomplish a lot on their quiet focus.

E. However, actually quiet people have their own strengths.

F. In this way, they will take the time to ensure what they are saying is true.

G. Less talking means more reflecting and observing, so they won't miss much.

The head, dating back to the Sui Dynasty (581-618), was originally placed on the northern wall in the No 8 Tianlongshan Grottoes on the suburbs of Taiyuan, capital of Shanxi province, according to a statement from the National Cultural Heritage Administration (国家文物局).

It was believed to be stolen and lost overseas around 1924, along with about 240 Buddha images that were robbed in the 1920s. This 44.5-cm-high Buddha head is the first among these stolen items to be returned from Japan.

The National Cultural Heritage Administration learned in September a Chinese Buddha head statue labeled as from Tang Dynasty (618-907) was about to be sold in Tokyo, and was thought to be a stolen piece from Tianlongshan.

The administration soon began the process of returning it home. In October, the auction house in Tokyo, whose board chairman Zhang Rong is a Chinese from Hangzhou, agreed to stop the auction.

After discussions between the National Cultural Heritage Administration, Zhang, and the local holder of the relic in Japan, the Buddha head was bought by Zhang and finally given away to the administration.

The transfer ceremony (交接仪式) for the statue was held in the Chinese Embassy (大使馆) in Tokyo in November, and it arrived in Beijing in December.

After being shown on the Spring Festival Gala, the Buddha head statue will be displayed in Beijing Lu Xun Museum from the first day of the Lunar New Year to Mar 14.

First of all, the job made huge demands on my strength. For ten hours a night, I took boxes that rolled down a metal track and piled them onto a truck. Each box contained twelve heavy bottles of apple juice. I once figured out that I was lifting an average of twelve tons of apple juice every night.

I would not have minded the difficulty of the work so much if the pay had not been so poor. I was paid the lowest wage of that time—two dollars an hour. Because of the low pay, I felt eager to get as much as possible. I usually worked twelve hours a night but did not take home much more than $100 a week.

But even more than the low pay, what made me unhappy was the working conditions. During work I was limited to two ten-minute breaks and an unpaid half hour for lunch. Most of my time was spent outside loading trucks with those heavy boxes in near-zero-degree temperatures. The steel floors of the trucks were like ice, which made my feet feel like stone. And after the production line shut down at night and most people left, I had to spend two hours alone cleaning the floor.

I stayed on the job for five months, all the while hating the difficulty of the work, the poor money, and the conditions under which I worked. By the time I left, I was determined never to go back there again.

When you travel abroad by yourself for whatever reason—exchange program, internship, volunteering, or simply as a tourist—a new and fascinating world will open up for you. A world you would have never been able to see if you had just stayed at home.

People from a different country are not aliens. They are simply people like you who happened to be born in another region. They have pretty much the same wishes and worries as people from your own country.

I know that you see a lot of news on TV saying terrible things people do all the time. Your family may have spent a great deal of time telling you not to trust strangers. However, when you travel alone you will realize that people are just as good as you. Everyone is just leading their lives, working, studying and having a good time with their friends. Most people will be happy to help you and get to know you.

Maybe in the past when you would need months to travel from one place to another, traveling could be expensive. Nowadays, the world is just so connected that it is perfectly possible to find cheap flights, accommodation for all budgets and cheap and quality food.

You will get lost, but it's fine! I can't even count how many times I didn't know where I was going or how to find the right direction. Everything looks great on Google maps, but sometimes your phone will die or your data will end. Just calm down. Go to a store or stop someone in the street and ask! Or simply walk around and be curious.

And yet, some people believe that we can create machines that can think and feel just like we do. Artificial intelligence, or AI is around us every day. From Apple's voice-activated assistant (声控助手) Siri to the software algorithms (算法) that shipping companies use to deal with deliveries (投递), AI is very much a part of our lives.

But why do we work so hard to create machines that can think the way we do? For one thing, AI can make our lives much easier. Imagine being able to be in a car, tell it the place you want to go to, and sit back in comfort as the AI-guided self-driving car takes you there. We are already getting there—Changsha became the first city in China where we can take self-driving taxis in April 2020.

However, there are risks. What if we somehow produced an artificial intelligence that was smarter than us? How would it behave toward us? These are the kinds of difficult questions that AI researchers ask themselves all the time.

Except for the risks, it is already clear that AI is here to stay. Only time will tell if it will lead us into a new age of prosperity (繁荣), or be our end.

②When I was still studying in China, my school held a singing competition. I entered it because I really loved singing. I sang with a girl named Jenny. She's one of my best friends.

③Unluckily, I was nervous and I forgot the lyrics for a moment while we sang. I was standing on stage, looking pale on the face. We lost the competition. I felt terribly sorry, but Jenny tried to comfort me by saying "There will be another chance."

④After about a week, our school's art festival began. I decided to enter it. The first person I thought of to join me was Jenny, although I wasn't sure if she would want to. But while I was asking other people to join me, she said she would join as well. We decided to sing the song See You Again at the festival because I would leave for UK after I finished the performance. We prepared for it for a long time.

⑤Finally, the day of the festival arrived. As I walked into class, people started clapping for me. Someone had written "Sally, Come On!" on the blackboard. My classmates wrote cards for me. After I completed my performance, everyone cheered for me.

⑥It was a really unforgettable and touching afternoon. I want to thank Jenny, who didn't give up on me when I felt down. I want to thank my friends for helping me, and I really want to thank all of my classmates who were with me in my two middle school years as well.

Leadership. What does the word mean? Leadership is not just the ability to lead a team, it is a journey of selflessness. Some people are born leaders while others are not. This was how I had to start my journey

"Alright, class! We are going to work in groups to create a mind map! It needs to contain the facts we discussed during the Science Centre trip!" Mrs. Low's voice boomed across the classroom like thunder. "This is a great opportunity for our newly appointed group leaders to prove themselves worthy of that title."

Mrs. Low then raised one of her eyebrows with great expectations. The class burst into non-stop chattering. Rita and John glanced at me warily. I raised my head, the gleaming badge (闪耀的徽章) with the words "Team Leader" pinned proudly on my uniform.

Mrs. Low instructed the class, "Go to your seats now." In the blink of an eye, everyone rushed back to their tables to begin their project. I took out a piece of paper and pointed to Rita, "Hey you! Make a list of the stuff that we have learned." Rita angrily slammed her hand on the table. She complained, "Why do you have to be so bossy?" "Because I'm the leader!" I shouted back. She glared at me with anger burning in her eyes.

I turned to John, "And you! Start drawing the mind map! I want it done quickly!" John did not protest; he simply bit his lip, muttering, "Is this really leadership?"

He went on to draw the mind map while his question rang in my head and I asked myself, is this really leadership? It was as if I was standing in front of a mirror, looking at my reflection, wondering if I was proud to see how I was behaving then. "Am I right to order people around like that? Should I be more polite and less bossy?" Questions bombarded my brain until I felt it was about to explode. I closed my eyes and sighed.

Suddenly, I felt a tap on my shoulder. I turned my head around. It was Mrs. Low. As though she could read my mind, Mrs. Low explained, "Leadership is not just about being a leader. It is to serve others, not yourself. It is a selfless journey."

In 2008, Japanese researchers, led by Hiroshima University cardiologist Dr Takayuki Yamaji, hired over 1,000 healthy Japanese adults. At the same time, the researchers tracked these adults' health for the next five years.

Eighty-four people were diagnosed with metabolic syndrome during those five years, with a clear connection between eating speed and development of the disease. The incidence rate was 11.6% among fast eaters, 6.5% among normal eaters and just 2.3% among slow eaters. Moreover, they had more chance to suffer from higher blood sugar.

In reality, a lot of research has shown that eating fast is associated with weight gain and other health issues. "You probably do eat more because you are eating so quickly. You really don't have any idea of what you've eaten," says American Heart Association spokesperson Dr Nieca Goldberg. "When you eat slowly, you are much more aware of your eating. You are chewing your food properly and you're also slowing down digestion."

Goldberg says that it should take at least 30 minutes to eat a meal. Goldberg suggests eating with a friend, cutting your food into smaller pieces, chewing more, taking deep breaths and setting your fork down between bites.

A. Doing so also helps you feel full.

B. Those results aren't all that surprising.

C. Eat in a situation where it's beneficial to eating.

D. The speedy eaters were also more likely to weigh more.

E. This shows that when it comes to eating, slow and steady wins the race.

F. So, if you tend to eat fast, you'll likely need to train yourself to slow down.

G. They asked the adults to characterize their eating speed — slow, normal or fast.

The Mars Oxygen In-Situ Resource Utilization Experiment, better known as Moxie, has been generating oxygen from the atmosphere on Mars, as part of NASA's Perseverance rover (漫游者) mission.

Moxie produced breathable oxygen in seven hour-long tests conducted in various weather and atmosphere conditions since landing. During each test, the device produced six grams of oxygen, about the same as a small tree and enough to sustain an astronaut for 15 minutes. It's also found that even in extreme temperatures and after a Martian dust storm, Moxie continued to produce high-purity oxygen.

"This is the first demonstration of actually using resources on the surface of another planet and transforming them chemically into something that would be useful for a human mission," said Jeff Hoffinan, a retired astronaut and professor at MIT.

NASA and the MIT team are planning to build a bigger version of Moxie, as they hope advanced models will produce enough oxygen to support a crewed mission to Mars. "We have to bring a lot of stuff from Earth to support a human mission, but oxygen is a big problem. If you can make it there, go for it and you're way ahead of the game," Hoffinan said.

The device uses pumps that absorb in carbon dioxide which is heated to 800℃and processed to separate the carbon and oxygen. Carbon monoxide (一氧化碳) is emitted as waste while the pure oxygen is left behind.

Expanding the device to support a human mission to Mars presents challenges. It is needed to run continuously for 400 days, a leap from the one-hour tests and its inner temperature should be controlled stably. Moxie has proved to endure the extreme conditions on Mars, however, and the team plans to assess the machine's limits in the coming months when atmosphere is thick and carbon dioxide levels are high. They say they just want to set everything as high as they dare and make as much oxygen as they can.

Why are rational people so irrational in their behavior? The answer is that we're in the midst of a bubble. I call it "The More Bubble".

The nature of bubbles is that something is overvalued until — eventually — the bubble bursts, and we're left wondering why we were so irrational in the first place. The thing we're overvaluing now is the opinion of doing it all, having it all, achieving it all.

This bubble is being enabled by a combination of three powerful trends: smart phones, social media, and extreme consumerism. The result is not just information overload, but opinion overload. We are more aware than at any time in history of what everyone else is doing and, therefore, what we should be doing. In the process, we have been sold a bill of goods: that success means being supermen and superwomen who can get it all done. Of course, we boasted about being busy — it's code for being successful and important.

And our answer to the problem of more is always more. We need more technology to help us create more technologies. We need to move our workload to free up our own time to do yet even more.

Luckily, there is a solution to asking for more: asking for less, but better. A growing number of people are making this change. I call these people Essentialists.

These people are designing their lives around what is essential and removing everything else. These people arrange to have actual weekends (during which they are not working). They create technology-free zones in their homes. They trade time on Facebook for calling those few friends who really matter to them. Instead of running to different meetings, they put space on their plans to get important work done.

So we have two choices: We can be among the last people caught up in "The More Bubble," or we can join the growing community of Essentialists and get more of what matters in our one precious life.

This was not because he was trying to pack as light as possible, nor was it because he was broke. I tried to convince him to at least add some soy sauce (酱油) to it. But no, Alex wasn't having any of it. "I don't need it," he said simply.

Now, if he was talking only about outdoors' meals, I almost understood the reason. When you're ravenous after a day of burning off calories walking or climbing or backcountry skiing in the mountains, how awesome do things taste! Just as the saying goes, hunger is the best sauce. And I agree. Absolutely.

But there's more to it than that. Last month, I went down the coast car camping with my family. One morning, my wife made a statement. "I don't see the point," she said. "It's so much work, camping. But the views at home are better. The beds are more comfortable. It's more peaceful. And at home, the food is better." I'll admit she's right about the first three. But the food? We had a simple pasta one night, snags another, chicken curry the third, but they all tasted good. Better than at home. And it wasn't simply that we were hungry; it was because we were camping.

The real point I want to convey is that meals taste particularly good when I'm camping because it reminds me of things that are easily overlooked at home, where I can just go to the cupboard or the supermarket and grab whatever I feel like. When you're camping, life is reduced to its essentials, and I'm reminded of how privileged most of us are to be dry, warm and fed. More importantly, I'm reminded that, sadly, not everyone is as fortunate as we are. And I'm reminded that, as a society, we should do better for them.

An event marking this year's Chinese Language Day was held on May 8 in London, bringing 100 students from six schools across the United Kingdom to celebrate the Chinese language and culture. (establish)by the United Nations, International Chinese Language Day is observed annually on April 20 to promote multilingualism and cultural (diverse).

The event, themed "Chinese Language: A Gift Across Time and Space", (feature)eight workshops highlighting various aspects of Chinese culture, including characters, calligraphy, poetry, martial arts, and opera masks. The activities mixed traditional, customs with modern elements, ranging from woodblock printing to virtual reality (experience). Along with workshops, students performed Chinese songs, posed for photos with a panda mascot, received souvenirs(纪念品).

"Learning Chinese is challenging, but also (incredible)fun and exciting. It has helped me understand Chinese culture, is different from the cultures I've experienced before," says Noah Eskinazi-Nehme, a student who (study) Chinese for almost two years and celebrates Spring Festival with his family each year. He wants to visit China one day to improve his language skills further while (explore)the country's diverse landscapes and seeing pandas.

Patrick Adamson, associate head teacher of Calday Grange Grammar School, says that learning Chinese enables students to "engage with China not as just a concept but as a living, dynamic culture" and "fuel curiosity and respect global perspectives"

Choose a goal.

Begin by choosing just one goal that you want to focus on to develop your self-discipline. For instance, perhaps you want to start exercising every evening. You could even practice self-discipline on very small goals such as concentrating on a book for an hour without checking your messages, or avoiding unhealthy food for one day.

Find your motivation.

Try to express these reasons in a positive way. Instead of saying "I want to get this task off my to-do list", say "I want to do this task so that I can meet my objectives and feel satisfied with myself!" When you list the positive reasons why you want to achieve something, you'll find it much easier to get the job done.

Identify barriers.

Now you need to identify the barriers that you'll likely face when working towards your goal. Imagine that your goal is to read one book a week to enhance your reading skills. For example, when you find a book you like, it's hard to find time each day to read. Once you've identified barriers, come up with a strategy to overcome each one.

As you work on your self-discipline, pay attention to how you're feeling. You might feel free, happy, proud, and energized. Also, think about keeping a journal to write down your self-discipline goal and to track your progress. This reinforces the positive changes that you're implementing (实施) in your life, and gives you a record that you can look back on to see the progress that you've made.

A. Monitor your progress.

B. Pay attention to your feelings.

C. Understand what helps improve self-discipline.

D. You may face a number of difficulties in reaching this goal.

E. It is a basic life skill that determines success and happiness.

F. Once you've chosen a goal, list the reasons why you want to achieve it.

G. Remember, starting small is a good way to start developing your self-discipline.

In their paper published in the journal Nature, James Larson, David Thompson and James Hurrell describe how they used satellite data and numerical modeling to better understand the impact of western boundary currents on local climate variability and what they learned by doing so.

Boundary currents are, as their names suggest, ocean currents that are impacted by coastlines associated with land masses. They fall under two main categories, eastern and western. Eastern boundary currents are those that have an eastern boundary, which means they run against the western coast of a land mass. Western boundary currents are the converse:

In this new study, the researchers noted that prior research focusing on the impact of boundary currents has typically focused on mean climate impacts — western boundary currents, for example, are known to move huge amounts of warm water from the tropics (热带) to the mid-latitudes. Because of that, they have a major impact on wind, rain, and storms, in general.

For this study, the researchers wanted to learn more about the role western boundary currents play in local weather variability. They analyzed high-resolution satellite images and used numerical models to find associations between factors such as sea surface temperatures (SSTs) and vertical motion in the atmosphere over western boundary currents in both hemispheres (半球). More specifically, they looked for associations between SSTs and circulation (环流) of air in the atmosphere on a month-by-month basis at a localized level.

The researchers found what they describe as variability in SSTs and their influence on local atmospheric circulation, which has an impact on rainfall amounts and the vertical rise and fall of air in the atmosphere. The team sums up their findings by suggesting their work has shown that there is a mechanism that connects ocean processes to local climate variability. They suggest this finding could have an impact on weather forecasting models.

One night while doing homework, my son told me about a classmate who had been unkind to him. My first instinct (本能) was to rush to fix it — email the parents, call the school, and demand action. But instead of reacting, I paused.

"That sounds hard. What did you do?"

"Dad, I decided not to hang out with him for a while," my son replied. "I'm going to try playing soccer at lunch instead."

"That's a great solution," I said, and he went back to his homework.

These otherwise ordinary parenting moments made me realize a truth: Sometimes, the best thing a parent can do is nothing at all.

I've spent the past 30 years working in schools, and I've watched thousands of parents engage with educators and with their children. Too often, I watch parents over-functioning — depriving (剥夺) their kids of the confidence that comes from struggling, and tiring themselves in the process.

We're biologically wired to prevent our children's suffering, and it can be painful to watch them struggle. A parent's first instinct is often to remove barriers from their child's path. This urge has led to pop-culture mythology (神话) around pushy parenting styles, including the "Helicopter Parent", who flies in to rescue a child in crisis, and the "Snowplow Parent", who flattens any barrier in their child's way.

A young person who grows accustomed to having a parent intervene on his behalf begins to believe that he's not capable of acting on his own, feeding both anxiety and dependence.

I want to make a case for the Lighthouse Parent. A Lighthouse Parent stands as a steady, reliable guide, providing safety and clarity without controlling every aspect of their child's journey. Yes, parenting can be stressful. But when we trust our children to explore the world — with us as steady and supportive guides — we lighten our own load and help them grow healthily.

So last fall, the Oakland, California, teenager took a different approach. He started applying to colleges. More than 150 of them. Before long, he got an acceptance letter. Then another. And another. The trickle (细流) became a flood until there were 122 of them — along with some $5. 3 million in scholarship offers.

His father says he's proud of Helms' 3.94 GPA and had hoped his son would pick a career with financial stability, like medicine or computer technology. But as he watched the mountain of acceptance letters in his son's room get bigger with every mail delivery, Chris Ategeka's hope disappeared.

"He's so confident that music is what he wants to do. It would be wrong for me to try to guide him otherwise ... That's why he applied to many colleges to prove a point," Chris says. "I told him, ‘You want to be a musician? It takes a lot of hard work.' And his reaction was, ‘I'll use my determination to do this to show you how hard I can work.'"

But how does an 18-year-old begin narrowing down such a massive list of options? "I live for music. I spend most of my time either listening to music, making music or out there performing," Helms says. "I feel the most alive and fulfilled when I'm doing something related to music."

So when he started his college application journey, he had one key requirement: the school needed to have a strong music program.

Helms spent the past few months studying the websites and social media accounts of schools that accepted him. He's watched videos of their music programs on YouTube and TikTok to get a sense of where he fits in. After months of research, Helms made his choice: he will stay nearby and study music at UC Berkeley. A spokesperson for Berkeley confirmed that he's been accepted.

Moving goods and people around the world is responsible for a large part of global CO₂ emissions (排放). As the world races to decarbonize everything, it faces particular problems with transportation — which accounts for about a quarter of our energy-related greenhouse gas emissions. Here's the breakdown of the emissions in 2018 for different modes of transport.

The fuels for transport need to be not just green, cheap and powerful, but also lightweight and safe enough to be carried around. Each mode of transport has its specific fuel needs. Much is still to be settled, but here are some of the solutions to get us going green.

This energy transition (变革) is global, and the amount of renewable energy the world will need is "a little bit mind-blowing," says mechanical engineer Keith Wipke at the National Renewable Energy Laboratory. It's estimated that the global demand for electricity could more than double by 2050. Fortunately, analyses suggest that renewables are up to the task. "We need to speed up the development of green energy, and it will all get used," says Wipke.
