What is the world's (small) country? You could decide to look at populations or the actual areas countries occupy to find your answer. In this case, the answer is same either way: Vatican City.

So, exactly how tiny is this country? Vatican City is a mere 0. 2 square miles (0. 52 square kilometers), is smaller than New York City's Central Park. Nevertheless, it has its own post office, telephone system, radio station, banking system and even its own currency, the Vatican euro. About 800 people live here.

Vatican City is an independent country, it's not recognized by the United Nations. Instead, Vatican City (consider) a permanent nonmember observer, which means it's welcome to sit in the UN's General Assembly and access most UN (serve) and benefits, but it can't vote. And that's just fine with Vatican City.

Unlike Palestine, which has (repeat) applied to become a full member of the UN, Vatican City has never done so. In fact, it's the only nation ever (decline) UN membership. In addition, if it were to apply for membership, the UN might challenge the idea it's a true country. According to the UN's definition, this (include) the ability to assist with global security.

I3 most of the weeks in the classroom, helping the children with their work4 and in groups and also reading with them. I was also extremely lucky to be able to5 them on a range of school trips. We watched a TV program, Horrible Histories, in an old barn, and traveled to Wales to see Roman baths and the ruins of their old barracks (营房). My favorite6 by far was the opportunity to participate in a Christmas carol service inside Bristol Cathedral.

As with all jobs, the fun didn't come without its set of7. A large percentage of the children in the class had special educational needs which, at times, were very hard to manage as I previously had8 experience with this.9, it was so gratifying to learn how to work and form relationships with each of these children in their individual ways. One of my fondest memories is the coach ride back10 Wales when I sat with one student with autism (自闭症). We spent the whole coach ride laughing and singing together,11 our own songs while he tried to convince me to download his favorite video game.

The whole experience was undoubtedly rewarding and something I will always12 on with joy. Even the routine of reading with the children was made fun by the13 of characters and personalities within the class. Working with children can be14, but I am so pleased I was able to have this experience.

During the placement, I learned a lot about patience, understanding, and the joy of seeing children learn and grow. It was15 a life-changing experience.

Assess your digital habits

Do you sometimes feel overwhelmed by excessive information or stressed by social media? Are you anxious when you forget your phone? If negative emotions are associated with your digital devices, it's time to improve your digital well-being.

Gaining a detailed understanding of your technology usage is crucial for improving your digital well-being. Many smartphones now offer activity monitoring features, enabling you to analyze the time spent on each app and device. Becoming aware of your habits will help you make informed decisions about your digital engagement.

Set the boundaries

We are surrounded by digital devices. We live in a world of tech! However, we are failing to set healthy tech boundaries.Once you hit the limit, the apps and sites pause and notifications are silenced.

Enjoy gadget-free meal time

Traditionally, meal times served as occasions for families and friends to relax and talk about their day. To promote meaningful communication and connection, it's important to have technology-free meals.

Establish a bedtime routine

To improve the quality of your sleep, consider disconnecting from your phone or other devices before bedtime. There are various apps available that can put your phone in nighttime mode, silencing notifications and turning your screen grayscale (灰度).

A. Monitor your digital activity.

B. Be aware of your well-being.

C. Reflect on how digital devices make you feel.

D. You can set daily limits on the apps and websites you use.

E. This reduces exposure to artificial blue light, which can make it harder to fall asleep.

As cities develop, some sources of carbon emissions (排放) may be hard to notice for most people, for example, the bricks used in buildings. US company Biomason has produced bio-based cement (水泥), which can sharply cut emissions during traditional cement production.

"We grow cement the same way nature does," wrote the company's website. How the cement is "grown" is based on biomineralization, the process by which living organisms produce minerals. One example of biomineralization is coral reefs. Massive reef structures are formed when each individual stony coral produces calcium carbonate, a kind of mineral. Although the stony corals are tiny, one reef structure, built by millions of stony corals, can grow to weigh several tons.

This biobased cement alternative is called Biolith. During the production of each Biolith tile, bacteria and nutrients are mixed with sand. Organisms then produce calcium carbonate by absorbing a liquid made of calcium and nitrogen (氮). However, the process doesn't change the size of the Biolith tile instead, it increases the density. The produced calcium carbonate forms bridges between the grains, strengthening the unit from within. It takes less than 72 hours to let a Biolith tile "grow" fully, while traditional concrete requires about 28 days to make a brick.

The company aims to "remove 25 percent of carbon emissions from the concrete industry by 2030," according to its website. Traditional concrete is made of crushed stones. The process involves heating the stone to temperatures greater than 1,300 ℃, during which carbon dioxide is emitted. The manufacture of Biolith, however, doesn't involve heating, which greatly reduces carbon emissions. The company plans on increasing the use of bio-based bricks, covering 35,000 square meters in Europe by the end of this year.

Math anxiety — a negative emotional reaction to the core subject — causes fear, physical suffering and behavior problems among young pupils, according to a University of Cambridge study. In ordinary life, many people experience some degree of discomfort when confronted with a math problem, ranging from mild tension to strong fear.

Some people also experience physical symptoms such as sweaty palms or a racing heart. They may then try to avoid numbers-related situations, meaning they are held back from pursuing careers related to the subject, such as science, technology or engineering, according to The Guardian.

Relief comes from the fact that those with math anxiety aren't destined to be bad at math. "If a child has math anxiety, don't assume that they're not good at math. They may have had a really bad experience with math," Daniel Ansari, the senior author of the study told The London Free Press. "Students with math anxiety are not cognitively (认知地) disadvantaged. "

Also, there are ways to manage your math-related stress. If you're stressed before a math exam, spend a few minutes exploring those feelings before the exam begins. "It's about making sure you're interpreting your feelings correctly," Sian Beilock, a cognitive scientist told the BBC. "A fast heartbeat and sweaty palms don't necessarily mean you will fail."

A little math anxiety could be taken as a positive challenge to overcome. Just like many people get stage fright before delivering a speech, this nervous energy can help to motivate, according to Ian Lyons, a psychologist at Georgetown University.

Math doesn't come easy, no matter how clever you are. Leonardo da Vinci, the famous Italian artist, was a huge fan of mathematics. But his notebooks show that Da Vinci couldn't do fractions (分数). He could never grasp, for instance, that dividing a number by one-quarter is the same as multiplying by four, resulting in a higher number than the original.

Some may characterize it as a love-hate relationship, even though I believe the bond between us is more than that. Of course, on the "hate" side there were plenty of frustrating hours spent practicing, the forced performances for relatives, the trimmed fingernails. And the responsibility I had to shoulder, as my family sacrificed a lot for me to have piano lessons, because I had talent. My teachers said so and, truthfully, my heart said so, too. But all too often it felt like a burden.

There was also love on that piano bench. There were times when I could feel the music ring through me. I could feel it vibrate through my fingers. The connection between two people when performing a duet was beautiful. When my music landed on my audience it made me want to play forever.

But my musical talent did not survive my teenage years. It was no competition for the freedom I sought and eventually fought for. When I had a home of my own, the piano mostly sat unloved or at least unused, feeling fingers on the keys only during Christmas and when my own children took piano lessons.

I know every inch of this piano. I spent years of my life in front of this piano. Awaiting my free will to ripen enough to release me from lessons. Awaiting my life to begin. Awaiting my mother to leave the room so I could secretly read my book while practicing scales.

It feels like I am giving away the family pet. So here I sit playing my last tune before the movers take the piano away and surprisingly there lies a growing desire for something else. It is time to clear the air to let in a different melody. Time to say, "Thank you for being part of my life," take a bow and leave the stage… with one final note rising up alongside the dust in a sunbeam.

An A for Mrs. B

I was sitting next to Missy in my ninth-grade world history class when Mrs. Bartlett announced a new project. In groups, we were to create a newspaper around the culture we were studying.

On a piece of paper, we wrote the names of three friends we wanted in our group. After collecting all the requests, Mrs. B. informed us that she would take into consideration the names we chose and would let us know the results the next day. I had no doubt I would get the group of my choice. Only a few people behaved normally in the class, and Missy was one of them. I knew we had chosen each other.

The next day, I anxiously waited for the class. After the bell rang, Missy and I stopped talking as Mrs. B called for our attention. She started to call out names. When she reached group three, Missy's name was called. So, I'm in group three,I thought. The second, third and fourth members of the group were called. My name was not included. There had to be some mistake!

Then I heard it. The last group: "Mauro, Juliette, Rachel, Karina." I could feel the tears well in my eyes. How could I face being in that group—the boy who rarely spoke English, the one girl who was always covered by skirts that went down to her ankles, and the other girl who wore weird clothes. Oh, how badly I wanted to be with my friends.

I fought back tears as I walked up to Mrs. B. She looked at me and knew what I was there for. I was determined to convince her I should be in the "good" group. "Why. . . ?" I started.

She gently placed a hand on my shoulder. "I know what you want, Karina," she said, "but your group needs you. I need you to help them get a passing grade on this assignment. Only you can help them."

I was stunned. I was confused. I was amazed. She had seen something in me I hadn't seen.

"Will you help them?" she asked.

I stood straighter. "Yes," I replied. I couldn't believe it came out of my mouth, but it did. I had committed.

China is a country with a rich cultural heritage (遗产) (stretch) back thousands of years. However, with the passage of time and other factors such as natural disasters and wars, many of its cultural treasures have been damaged or destroyed. In recent years, China has used technology to protect its cultural heritage through digitalization so that it can (preserve) for future generations to enjoy and study.

One of the most notable (example) of China's digital preservation effort is the Dunhuang Mogao Cave Project, the goal of which is (create) a digital profile of the Mogao Caves with the help of 3D scanning and virtual reality software. Another example is the Palace Museum Project. Through the use of technology, the Palace Museum is now able to showcase the relics to visitors from all around the world risking damage to the precious artworks.

Digital technology has the potential to aid in the restoration of damaged artworks. A 3D printing technology enabled Chinese researchers to recreate the cultural relics, including ancient Buddha statues and bronze (青铜) lion from the Qing Dynasty.

(additional), China's digitalization of cultural heritage has been instrumental in research and education. The digital achievements have enabled researchers to study the artworks in greater detail ever before.

Digitalization has made cultural heritage more (access) to the public, particularly to people living in rural areas would otherwise be unable to visit these sites in person.
