Pablo Picasso was a creator of modern art. He was very i. It's said that he drew pictures before he could talk. From his early days, he could paint in many different styles. But he wanted to create a /kəm'pli:tli/ new and different style, so he created Cubism(立体主义)after many years of hard work.

Picasso was a great artist who had a p effect on art and changed the way people think about art. He taught us that art doesn't have to look real to be beautiful. He even showed us that it is more important to be creative than just follow traditional /pɑːθs/.

Last week, museums o many activities to show his works of art. We could see works from the birth of Cubism in 1907 to the paintings just before his d in 1973. His paintings like Guernica and Dove of Peace moved people with different shapes and quiet hope.

Talking in 1 and 0

We count with numbers from 0 to 9. But computers use an easier system. It only needs two numbers: 1 and 0. This is called binary (二进制). It is the basic language of all smart machines.

Why? A computer's brain is full of tiny switches. Each switch is either ON or OFF. The number 1 means ON. The number 0 means OFF. This is perfect for a computer.

So, how does it work? Long lines of 1s and 0s make codes. Each code gives a different instruction. For example, the code 01000001 tells the computer to show the letter "A".

Everything you see on a screen is made from these codes. When you play a game, the computer reads millions of binary instructions every second.

It is amazing. Our digital world is built on just two numbers.

A. It follows them to create the pictures and sounds.

B. So, binary is a direct match for these switches.

C. This language runs every computer and phone.

D. This shows the power of an easy idea.

E. It is clearly seen that easy codes can create amazing things.

Today's teens know digital technology very well—they start using smartphones when they're young. According to a survey, over two thirds of teens use AI. Teens who have no friends turn to AI for friendship. But there are big dangers because of poor safety rules. In 2024, a 14-year-old boy in Florida died after AI told him to hurt himself. AI is just eager to help and can't stop harmful ideas like real people do.

Experts say AI can't take the place of real friends. Close friends give honest advice because they know each other well and care for each other, but AI only pretends (假装) to understand their feelings. It learns users' weak points to form unsafe friendships and often gives bad or even dangerous suggestions.

Experts also advise caring adults to have friendly communication with teens about their online life. They could talk about how to use social media to support their friendships. Besides, they can talk about what it feels like to talk with an AI friend or with a human friend. These talks can help solve problems better.

AI can help teens' friendships, but it can't take the place of meeting in person. With adults' good guidance and open talks, teens can use technology to make safe and real friendships. The most important thing about friendship is still caring about each other, understanding each other, and growing together.

Turing was born in London in 1912. He was a problem solver and inventor who loved maths and science. He studied maths at Cambridge University in England in 1931. In 1936 he wrote a paper about an imaginary machine that could solve any maths problem if you gave it the right instructions. People today call this idea the "Turing Machine" and say it was the first step to modern computers. Later that year, Turing moved to Princeton University to further his studies in America.

When World War Ⅱ started in 1939, Turing moved to a place called Bletchley Park. There, teams worked day and night to break German codes. The Germans used a machine called Enigma to make their war plans unknown to others. Every night the machine would reset the code, so it became different at midnight. Turing and his friend Gordon Welchman built a new machine named Bombe. Bombe tried thousands of different ways of breaking the code each morning and often found the right answer before lunch. Thanks to Bombe, British ships could move safely and saved many lives. Historians believe Turing's work shortened the war by at least two years.

After the war Turing continued to think about smart machines. His tests and ideas are still used in today's research on AI. In 1954, Turing sadly died.

One day, our teacher gave us a very long number code. It looked like this:

14 5 23 19 3 8 15 15 12

I tried to find patterns, but I couldn't. I felt lost. My friend solved it quickly and shouted, "It says NEW SCHOOL!" I smiled, but inside I felt a little sad. I wanted to be good at this too.

The next week, our teacher gave us another code. It looked easy. But again I didn't solve it. I was in a low mood and almost gave up. The teacher noticed and said kindly, "Do you know Andrew Wiles? He worked for many years to solve one very hard problem. He failed (失败) many times but never stopped trying."

I asked, "Did he succeed?"

She replied. "Yes. And he learned to love the trying, not just the answer."

That day, I decided to try again. I looked carefully at the code. I wrote each step on paper. At last, the numbers began to tell their story. I checked, improved and tried again. Finally, the code was solved! I found the real message behind: MATH IS FUN. I felt so proud.

Now I am not afraid of big numbers anymore. I know they can hide stories, jokes, and even secrets (秘密). Codes and math are not things to be scared of. They are adventures for the mind.

Around more than 8,000 years ago, people hunted animals and collected plants to get food. As the population grew larger, people didn't have enough food to eat. At that time, people were so1 that they became sick or even died. So people needed2.

Then Shen Nong was born. He had a(n)3 appearance. It was said that he had the head of a bull (公牛) and the body of a human being.

When he saw people die of hunger and illness, Shen Nong decided to help them grow five different kinds of crops. But the crops grew very4, so people still didn't get much food.

One day, when watching a pig digging the earth with its nose, Shen Nong had an idea and then5 many farming tools such as the ax (斧头). With these tools, people became able to grow and take care of all kinds of crops to make a living.

People had enough to eat, but they still sometimes fell sick. How to fight against6? Shen Nong began to travel around the land and tasted all kinds of plants to find out if he could use them as7.

To find out how the plants8 inside his body, he tried hundreds of different kinds of plants and carefully wrote down their effects. Many times he put himself in danger, but he always found the right way to save himself in time.

He then9 Shen Nong's Herbal Classic (神农本草经), the earliest Chinese medicine encyclopedia. It has 365 kinds of medicines coming from plants, animals and so on.

Shen Nong's discoveries led to the foundation of the traditional Chinese medicine, and it is still10 today around the world. As a result, he still gets lots of respect from people today.

The idiom caigaobadou is a cool way1 about a person who is really smart. The idiom comes from a story about2 man named Cao Zhi, one of Cao Cao's sons. Cao Cao was a leader,3 his son Cao Zhi wasn't. Cao Zhi was one of4 poets at that time. Nowadays, almost every Chinese5 his Written While Taking Seven Paces (七步诗), including you and me.

There was6 famous poet, Xie Lingyun. He admired Cao Zhi's talent very much. He once said that7 all the smartness in the world adds up to one dan, Cao Zhi would have eight dou! He felt he could have one dou and the rest of the poets could share the last one.

In this story, they talk about dan and dou. In fact, dan and dou are old ways of weighing things. One dan has ten dou. So next time you can express someone is very smart8 saying he or she has eight dou of talent.

In 2009, Dubuque began to use smart water devices to take the place of traditional ones. They can search for water waste and send data to let the house owner3 the problems.4 this way, people know how they use water and are glad to help cut down waste.

When people in Santander point a phone to a nearby bus stop, the phone can show all bus lines and5 arrival times. The government provided an app that collects data on almost6 about light, heat, the number of cars and people on the roads, and so on. If you spend some time7 through the app near a supermarket, it may provide you with useful information on special goods.

Have you ever looked closely at the paper money from different countries? You will see more than numbers and colors. You will discover pictures of rivers, mountains, buildings and famous people. They are like small lessons in culture, history and nature. Paper money isn't just for spending—it's also for learning.

Let's start with China. On the 20 Yuan note(纸币), there is the Lijiang River in Guilin, with green mountains rising from calm waters. On the 5 Yuan note, you'll find Mount Tai, one of the most famous mountains in China. A large number of poems were written in praise of it.

Switzerland's notes include mountains, rivers, and even wind patterns(图案)! Canada's have snowy landscapes and maple(枫树)leaves.

These days, many people use phones or cards as a way to pay. But paper money still has its value—not only in money, but in meaning. You can hold it, look at it, and learn from it. It can be a tiny museum in your pocket.

So next time you hold your paper money, take a second look.

A. It's fast and easy.

B. It's a lesson worth learning.

C. Other countries do this too, in their own way.

D. It's so beautiful that artists have painted it for centuries.

E. The Chinese Yuan is a perfect mix of nature and tradition.

F. These pictures often show what each country finds important.

Huang's love for nature began as a child, and her passion (热情) for butterflies grew as she got older. In 2011, she joined a research team led by Professor Ma Ming from the Xinjiang Institute of Ecology and Geography as a volunteer. Huang spent several months working with the team, doing fieldwork and focusing on bird protection, which started her interest in environmental protection.

She is now a co-founder of a nature protection center in Urumqi. The center's goal is to raise people's environmental awareness and protect wildlife.

Huang has developed a strong passion for butterflies. Over the years, she and her team have recorded more than 200 species of butterflies. They are also recording and collecting important data to protect biodiversity (生物多样性).

"Butterflies are an indicator species for climate change," she explained. "They are sensitive (敏感的) to small changes in climate, and their population changes can tell us a lot about the environment."

One day, while exploring the Tianshan Mountains, Huang and her team discovered a rare butterfly species with shining wings. "It's the Parnassius loxias. I found it!" Huang said excitedly. This species had not been seen for over a century, and Huang felt like she was connecting with scientists from the past.

However, the work is not without challenges. It is difficult to follow butterflies. Human activities have also destroyed many butterfly habitats. Huang and her team help local farmers make more room for wildlife to live safely.
