During the Spring and Autumn Period (春秋时期), there was a master (大师) of the Guqin instrument named Yu Boya. He always found his (idea) from nature. During a boat trip to the State of Chu, the sight of the river and mountains inspired (he) to play. After a while, he noticed Zhong Ziqi, a woodsman, standing (quiet) on the bank,enjoying the music. Yu invited Zhong aboard.

Yu played music that described the high mountains. Zhong said, "Wonderful! I see the grand (雄伟的) Taishan Mountain!" Yu then played music describing the flowing water, and Zhong said, "Wonderful! I see the rushing river!"

Yu was (surprise). "You really understand my music!" Then the musician and the woodsman became good friends. They decided (meet) each other again at the same place the next year.

When that time came, Yu arrived and found that Zhong had died of illness.

Yu felt very sad. He (take) out his Guqin and once again played the music of the "high mountains and flowing water".

"My (good) friend has passed away," he said. "No one in the world understands my music anymore." he broke his Guqin and never played it again.

This story tells us that true friendship isn't about who you are or how long you've known each other. Instead, it should be about two people sharing the same feelings each other.

In a clear tank of water (水箱), fish are swimming happily. But wait a second: look closer at that blue one.

This scene happened at the World Digital Education Meeting from May 14 to 16 in Wuhan, Hubei province. Scientists at Wuhan University invented the robotic fish. The pretty colors of them came from the LED lights on their bodies. These lights could also give the underwater world a party feel.

The robotic fish were about 53 centimeters long. That's why the robotic fish acted like real ones. With the special design, they can move fast and easily.

"I love to see the robotic fish," Professor James Crabbe from Oxford University told the media. "It could tell us much more about fish groups and how fish behave (表现)."

Fish swim together in large groups. The robotic fish helps us learn about fish groups and understand how real fish live. It can also show how changes in the environment influence them.

With the help of AI and sensors (传感器), they can "see" things in their way and learn to avoid them. They are already helping in the study of the Yangtze River's water to help protect the environment.

A. It is actually a robot!

B. Even better, these fish are smart.

C. They weighed about 1.1 kilograms.

D. It helps them stay safe, find food and save energy.

E. Besides the blue ones, there were red and yellow ones, too.

F. The bionic joints (仿生关节) were put in their heads and tails.

Since it opened in 1973, nearly 57 million people have visited the museum. However, AP News reported that the museum might have to close if the government doesn't offer more money for necessary repairs. These repairs are important to keep the art collection and visitors safe. During the repair work, some parts of the museum will be shut down. This means the museum will earn less money from ticket sales.

In fact, ticket sales alone can't cover the costs of running a museum. Museums need help from the government and rich people. For example, in the United States, the National Endowment for the Arts (国家艺术基金会) and other organizations provide money for specific projects, repair work and daily operations (运营). This public support shows that museums play an important role in education and culture. Besides, art collectors and even ordinary visitors may give money to museums.

Museums also make money through different activities. Some museums now have nice gift shops and cafes. Visitors can buy books, gifts and branded merchandise (品牌商品) there, and they can also enjoy food and drinks in the cafes.

Museums have changed a lot over time, and they keep looking for new ways to give visitors better experiences and attract more donors (赞助人).

The drone program was started to follow our country's plan for AI education. Drones bring together many subjects. By controlling them, students can learn about machines, coding (编程) and how air works, while also improving their thinking and practical skills.

To take part in a drone competition, students first need to take a lesson to learn about drone structure (结构) and flight rules. After that, they write codes to control drones. Then they practice flying them. Before the competition, there is even special training for them.

Many students attended the program. Student Yang Bailiang joined the class with a big dream: "I hope drones can solve real problems. For example, fire engines can't always reach the top of buildings, but drones can. I want to learn about drones to help people."

Student Xie Yuqi remembers his first flight: "I was nervous at first, but when the drone took off smoothly, I felt excited." He added with a laugh, "I will surely introduce this class to my friends. They can enjoy the success!"

For the students, besides knowledge, they can get a lot from the program. When students make drones fly the way they planned, that success changes how they see themselves.

The 11 digits are divided into three parts. Each part has a different meaning. The first three digits tell you your mobile phone service provider. The fourth to the seventh digits tell you where the number appeared for the first time. The last four digits are chosen freely.

The main reason for using 11-digit numbers is China's large population. We once used 10 digits. But as our population grew, that was not enough. From 1999 on, we started to use 11-digit numbers, which can create tens of billions of numbers. This is enough for every person to have several numbers.

Mobile phone numbers can be recycled (回收). Usually, a service provider will reuse a number if it has been stopped for three to six months. So if you call an old number, a different person might answer!

Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia, and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the shortest in the world: they use seven digits.

Giraffe was very proud and often looked down upon (瞧不起) other animals. His friend, Mouse Deer, seldom received any1 from him. Though Mouse Deer felt unhappy, he never argued and always kept his2 to himself.

One day, Mouse Deer decided to3 Giraffe to catch him. Giraffe agreed. When the competition began, Mouse Deer ran quickly along the narrow (狭窄的) road thanks to his4 size. Giraffe could run faster in open areas. But sometimes he had difficulty5 Mouse Deer's sharp turns because of his large body. Soon, Mouse Deer ran into a dark cave (洞穴). Giraffe ran right after him confidently.

"Ouch! Help me!" Suddenly, Giraffe fell to the ground and hurt his leg. Mouse Deer quickly turned back and found Giraffe lying in6 "Don't worry," said Mouse Deer in a gentle voice. "I'll help you stand. Look, the light is not far. That's our way out."

By working together, they got out of the cave7. Mouse Deer used some leaves to treat Giraffe's leg. Giraffe was8 and asked, "Why did you help me even though I was never kind to you?" Mouse Deer replied, "Because we are friends. That means we should9 each other. Everyone has their own strengths and weaknesses. No one is perfect."

Giraffe finally understood. From that day on, he became a more caring friend. And their10 grew stronger than ever.
