For two people, a classic rule works well: "I cut, you choose." One cuts the cake into two pieces. The other person picks first. The cutter will try to make it fair, so both feel satisfied. However, it is more difficult for three people. In the 1940s, mathematician Hugo Steinhaus introduced the "lone-divider" method. First, Amy cuts the cake into three pieces that she values equally (均等地). Then Ben and Charlie check the pieces. If they both accept different pieces, they each take one, and Amy gets the last one. So everyone gets a piece that they believe is fair.

Later, in the 1960s, John Conway and John Selfridge developed another method. A piece of cake is passed from one person to another. Anyone who thinks it is too big may cut a part off. Any pieces cut off are put back with the main cake. The last person to trim it gets that piece and leaves. Then the same process continues with the rest of the cake and the remaining people. This method also aims at fairness.

In 2014, researchers created Spliddit, a website that uses these math rules to help people divide things fairly. As mathematician Biaoshuai Tao said, "There's a lot to be done." Cake-cutting shows us that even simple daily problems can lead to deep and useful math.

But on the way to the store, he started to think. "What is a green onion? It must be an onion that is green." When he got to the store, he looked at all the onions. There were red, white, and purple onions—but no green ones. He felt2.

Then he had an idea. "Maybe the inside is green." He3 a white onion and took off the skin. Inside, he saw a light green colour. "Yes! I found it!" he thought4. He bought the onion and took it home.

When he gave it to his friend, his friend looked puzzled. "Why did you buy a white onion? I asked for green onions."

Luen5, "Look—the inside is green!"

His friend laughed. Then he said, "A green onion is6. It has long green leaves and a small white end. People use the green part for7. It's not just an onion that is green."

His friend8, "In English, some words are made of two words. They're called compound words. But the9 isn't always what you might expect. For example, an eggplant doesn't have eggs. A hot dog isn't a dog."

Luen felt a little embarrassed, but he also felt happy. He10 something new from this experience. And he would never forget what green onions really are!

When I was six years old, I had2 front tooth that often moved. I could push it back and forth with my tongue. It made3 worried. I didn't know what was happening, so I went to my mom.

Mom looked at my tooth and smiled. "Don't worry," she said. "Your tooth is going to fall out soon."

"Fall out?" I cried. "How will I eat?"

Mom laughed. "Everyone4 two sets of teeth. These are your baby teeth. They make room5 your grown-up teeth to come in."

6 I was still scared. "Will it hurt?" I asked. The thought of a tooth falling out made me feel nervous.

Mom said she could help. She asked me7 in a chair and close my eyes.

"Think about something funny," she said8. "I'm just going to take a look."

I closed my eyes tight and tried to think of something silly. After a few seconds, Mom said, "Okay, open your eyes."

There, in her hand, was my tooth! I9 believe it. However, my mother's smile told me everything was okay. While she was talking, she had pulled it out, and I didn't feel a thing.

That's just how moms are. They know exactly10 to do. And they always find a way to make things better—and painless.

I hope you can learn more about Chinese traditional culture and love it.

He finished reading the novel in  .

The oldest paper-cutting in China can  over 1,500 years.

The new students made a good  the whole class.

He   straight and answered the teacher's question loudly.

They saw a notice for voluntary work at the nursing home,so they  help.

Shenzhen Bay Park is helping migratory birds by dimming(调暗)its lights  night. Every winter,thousands of birds fly over the city on  long journey.The park is on a famous bird"highway"called the East AsianAustralasian flyway.Too much bright light can confuse birds and make it hard for  (they)to rest or find their way.

Some people were surprised at first,  most of them now think it is a great idea.The city uses warm yellow  (light)instead of bright blue ones.It also  (use) hightech(高科技)weather radar to track(跟踪)the birds.This helps the park decide exactly when the lights  (turn)off at night every day.

Many people feel  (excite)and inspired by this thoughtful action.They cheer for Shenzhen Bay Park's effort and believe it sets a wonderful example.Other Chinese cities,like Beijing and Chengdu,also hope  (control)their nighttime lights.People realize that a beautiful city does not need to be bright all the time in order to help those lovely birds.This plan shows that  (protect)nature can be easy and helpful.

Making eye contact during talks is very important.   In fact,making good eye contact is one of the social skills (社交技能)everyone should work on.

It makes people remember you.

 If you want to make them remember you,what can you do?Making and keeping eye contact with them can help you make a good and strong impression on others easily.

It makes people trust (信任)you.

  If you don't do it or you keep breaking eye contact to look away,they will think you are worried or scared and question (质疑)what you are saying.

When you notice someone is looking at you,you will pay more attention to your own behaviors and try to act properly.Taking note of your actions is a good thing.

It lets people know what you are saying clearly.

  But if you keep eye contact with your listeners,you'll speak more slowly and it will make them hear you more clearly and understand you better.

The beautiful dragon robes(龙袍)of Chinese emperors are long gone,either buried or locked behind museum glass.But the skills to make them still exist,thanks to artists like Qi Qiulan from Suzhou,Jiangsu province.

Qi is 62 years old.Her family has a long history of embroidery(刺绣):her great-grandmother made dragon robes for the Forbidden City,and her mother made embroidered things for export.Qi cannot remember a time when she was not surrounded by silk and thread.By age 4,she was sitting at her mother's feet, watching a needle dance through fabric.By age 6,she was doing it herself —mending clothes and embroidering small patterns."I was born into this.It's in my blood.We call it children's kung fu. The skills you learn when you're young never leave you,"she said.

In 1988,she opened a small shop in Suzhou.She worked very hard,and her shop later grew into more than 30 big stores.Qi's works are famous.She made clothes for world leaders at the 2014 APEC meeting and gifts for first ladies at the 2016 G20 Summit.One of her great achievements is a15-meter-long embroidery copy of The Prosperous Suzhou Scroll,a Qing Dynasty (1644 -1911) painting.It took 20 people six and a half years to finish it.She plans to exhibit it in a museum.

Qi thinks Suzhou embroidery is a national intangible heritage."This craftsmanship is unique in the world.Silk used to be called soft gold.We have to let people know its value,"she said.She worries young people don't want to learn this craft.But her son Xu Ting,a university graduate, joined her business.He said,"What we're doing is meaningful.We're spreading Chinese culture."

After Wang Yizhi graduated from Shanxi Agricultural University in 2023,she made a meaningful choice to join the"Go West"program and work as a volunteer teacher in Xinjiang. Through this experience,she not only helped local students but also found the true value of life.

Wang went to a primary school in Xinjiang and started her work as a Chinese teacher.At first,she met many challenges and even had some doubts about her choice.However,she never gave up and gradually found the experience rewarding.She felt especially happy when she witnessed her students'progress and gained the trust of their parents.

Since 2022,all the teachers in this school have been volunteers.Currently,23 volunteers are teaching more than 300 students.Because of their hard work,the students are doing much better in their studies than before.What's more,their spirit has won high praise.On May 2,2025,President

Xi Jinping replied to a letter from the young volunteer teachers.He praised them for their great efforts in local education and said volunteer service is important for social progress.He also hoped more young people could spread truth,kindness,and beauty to the world.

In a word,Wang's volunteer experience in western China is very meaningful.It helps her understand the true meaning of life and makes her decide to continue her work as a volunteer teacher.

Come and Help with the City Games

Our City Games will be held from July 20th to July 28th,

2026.We need 2,000 volunteers.The jobs are open to people over 18 years old.Those who have the experience of volunteering in sports events will be chosen first.

In late 2024,three brothers found a very old comic book in their mother's attic(阁楼).It was Superman 1,the first issue of Superman's own comic series. 1 ,the book was over 80 years old,but it was in excellent condition.In November 2025,it was sold for $9 .12 million,becoming the world's most 2 comic book.

Superman was created by two high school 3 in 

1933.Both of the students were still studying at a high school at the time.The brothers knew their mother had a comic collection,but they had never 4 the box before finding the comics.After she died,they found the comics in a cardboard box in the attic.The copy of Superman 1was from the 5 printing.

Why is this comic worth so much?Its excellent condition is one reason. 6 ,it came from the first printing.Most of the 500,000 copies printed are no longer in good 7 because the comic once encouraged children to cut it up.That means very few complete copies remain. That's the 8 reason why this copy is so valuable.

The brothers said the sale is not just about a rare comic.It is about family,and how the past can suddenly find its 9 back to us.Lon Allen,who worked for the auction(拍卖)house, said he was 10 by the sale.He added that this comic was truly the best copy he had ever seen.

—That's right.
