What has happened? These are just the types of problems a solar storm (太阳风暴) might cause. You may not think of storms as putting our society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares (太阳耀斑): large explosions (爆炸) near the sun that can give off lots of energy. The strong energy can stop the satellite systems (卫星系统) that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine's Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

"Solar flare activity is going to be much worse than what we've seen in the past. We're not talking about a few cities losing power. It could be half of the country, maybe more." Solar storm Warning.com, a US website about space weather, warned.

Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

In 2020, Zhang Wei started DeepSeek, a company that uses Artificial Intelligence (AI) to solve real-world problems. One of their first products was an AI assistant (助手) that could help students with homework. It could answer questions, explain difficult concepts (概念), and even give study tips. Many students found it very helpful, and DeepSeek quickly became popular.

However, Zhang Wei also faced challenges. Some people worried that AI might make students lazy or take away jobs from teachers. Zhang Wei believes that AI is a tool, not a replacement (替代品) for humans. He says, "AI can help us learn better, but it cannot replace the creativity and care of a real teacher."

Today, DeepSeek is working on new projects, like using AI to help doctors diagnose diseases faster. Zhang Wei also believes that AI can help solve some of the world's biggest problems. For example, DeepSeek is now developing AI tools to help farmers grow crops more efficiently and reduce waste. Zhang Wei hopes that AI will make the world a better place, but he knows it must be used responsibly. He often says, "AI is not just about technology, it's about making life better for everyone." His vision has inspired many young people to study AI and work towards a brighter future.

I joined the line to2 for my turn. The weight of my coming baby made it3 for me to stand straight, and my legs felt heavy. I raised my head and saw there were still quite a few people ahead. Some were playing with their phones and some were talking quietly. The line moved so4.

I began to feel weaker in my5. I couldn't stand for long. "Should I ask the one at the front for help? What if he6? He's been waiting for a long time, too. Will the other people agree?" I thought to myself, "But I…" My forehead was starting to sweat (冒汗).

I knew I couldn't wait. I walked up to the7 person in the line and asked in a low voice, "Excuse me, could I go first? I am not feeling so well."

The young man looked at me in surprise8 he saw my belly (肚子). He agreed. Almost no one noticed what happened. I thought he would remain behind me. Instead, he moved straight to the end.

The story happened during the Warring States Period. In order to form an alliance (联盟) with Zhao, Wei had to send one prince to Zhao. The King of Wei (trust) Pang Cong most, so he asked Pang to go along with the prince.

Pang Cong was (worry) that someone would speak ill of (说……的坏话) him when he was away. Before leaving, he asked the King of Wei, "Your Majesty, a person comes to tell you that there is a tiger in the market now, will you believe it?" The king answered without (hesitate), "Of course not. It's impossible."

Pang asked again, "What if two people come to tell you that?" The king said slowly, "I might think about it for moment." Pang continued, "What if three people say so?" The king answered, "I'll believe (they)."

Pang said, "Your Majesty, there is (definite) no tiger in the market. But since three people come to tell you the same thing, you can't help (believe) it in the end. I'm going to Handan. There will be more than just three people who will slander (诋毁) me. Please do not believe those words and keep away those people." The king agreed.

After Pang left, many people came to the king (speak) ill of him. Although the king didn't believe it at first, as time passed by, he began to doubt Pang. After Pang returned to Wei, the king no longer believed him. This story tells us that we should have our own thinking.

Learning to manage your time wisely can help you get more things done. Just follow these tips to make the most of your time.   

Make a to-do list.

Write down the tasks you need to finish, like doing homework, helping with housework or watering a plant. This makes you realize which tasks are more important and need more time.

Organize your workspace.

Move away the things you won't use and put everything you need close at hand. This rule works for both your school study area and your home environment.

Do one thing at a time.

Doing many things at once means you have to jump between different tasks. It's really a waste of time. This way, you can fully focus on what you're doing and get it done more quickly.

Morning persons usually have the most energy soon after they get up, while night people might find they are energetic in the evening. Just find out when you are at your best and try to deal with important tasks during that period.

Avoid being aperfectionist (完美主义者).

It's common that you want to be better. Instead, just make sure you finish your tasks on time and meet the necessary standards (标准).

A. Do key tasks at your golden time.

B. But don't try to be perfect in everything.

C. Then consider how much time each task might take.

D. Try to complete only one task before starting another.

E. In this way, you won't waste time trying to find what you need.

F. You can also ask your family or friends to help you with difficult tasks.

A Fitbit tracks (追踪) a wearer's sleep throughout the night. According to data from Fitbits, the first group of adolescents slept an average (平均数) of seven hours and 10 minutes a night. The second group slept an average of seven hours and 21 minutes a night. The third group slept for an average of seven hours and 25 minutes a night. Across the three groups, there was a difference when certain tests such as word spelling and historical facts were taken. The researchers found that group three did better than group two, and that group two did better than group one.

Barbara Sahakian, a study author, said, "Losing just a little sleep each day can lead to big changes over the years. This effect may seemnegligible at first, but it slowly builds up to influence brain function (功能), especially during adolescence."

Another study author, Wei Cheng, said, "We next need to look at why some teens go to bed later and sleep less than others. Is it because of playing video games or using phones, for example, or is it just that their body clocks do not tell them it's time to sleep until later? We hope to find out scientific ways to help teens achieve quality sleep."

Now, some 25 years later, the Vegetable Orchestra has played more than 340 concerts using fresh carrots, pumpkins, radishes and other vegetables. The group has now set a world record for the most concerts by a vegetable orchestra.

The Vegetable Orchestra is based in Vienna, Austria, but performs all over the world. It has 11 members and they come from different fields. Some are musicians full-time, while others are artists, writers, or designers.

Making vegetable instruments takes time and skill. Before each concert, the musicians carefully choose fresh vegetables at the market. The size and shape of each vegetable influence its sound. They use tools to create instruments like pumpkin drums, carrot flutes, and celery guitars. During the performance, the vegetables slowly dry out and change sound under stage lights, making each show really special.

Naturally, these instruments are pretty single-use, so the orchestra has a cook that turns some unused vegetables into soup for the audience to enjoy after the performance. The vegetables that they don't eat become organic waste in the end.

The Vegetable Orchestra encourages the audience to attend their concerts with an open mind. It wants to show people how creative music can be. Next time you see vegetables, maybe you'll imagine them as musical instruments too!

I attended Sungkyunkwan University, a truly amazing university in the heart of Seoul. Built in 1398, it's the oldest university in the country. At the University of Reading in the UK, I studied graphic design, but in South Korea I chose to study more of the business side of design and the Korean language. I really benefited from the different views offered by the professors (教授) there.

I also got help from the Turing Scheme. Thanks to it, I could experience everything in the university without worrying about money. It allowed me to live life to the fullest there.   

But the best part of this experience was the people I met along the way. With them, I travelled to places like Pohang, Busan, Jeju, Incheon and more. It wasn't just other exchange students. The students at the host university were also friendly. I now have plenty of friends in South Korea.

I can say truthfully that I fell in love with Seoul. Actually, I'm writing this from Seoul months after my studying ended because I simply don't want to leave. Studying abroad is stressful, but I would do it a thousand times over. If you're considering it, let this be the sign to do it. I think it's better to regret (后悔) doing something rather than to regret never doing it at all.

In middle school, I skipped (跳过) a grade and began taking high school classes. But soon I found I was1 chemistry. The teacher thought we all had taken it before, but in fact many hadn't. Since we were not allowed to change classes, we had to keep learning without knowing the basics.

With my falling grades in the course and the warning of probation (学业察看) from the teacher, my2 began to drop.

One evening, after3 my grades on the computer for my latest chemistry exam, I cried. I had spent a few weeks studying and practicing, but I still4. My five-year-old brother walked by and saw my tears. He put his toys down, climbed into my arms, and comforted me. "Don't be5. I will give you a(n)6 so you'll be happy."

He then ran to his room and came back with a colourful drawing he'd made. It was a picture of me he had put his heart into drawing. He7 gave it to me, saying it was a masterpiece (杰作) just for me. He then started to tell me8 stories about his toys, which made me laugh. Finally, his efforts made me forget my9. At that moment, my little brother's love became the guiding light and gave me strength to face challenges. From that day on, I10 to work hard and little by little, my chemistry grades improved. In the end, I not only passed all the chemistry exams but also excelled in the subject.

With the development of China, great changes have taken place in our life over these years.

Firstly, people have more and more ways to learn. For example, we used to have classes only at school, but now thanks to the development of the Internet, we can take online courses, which can create a safer environment to have classes if there is a pandemic (疫情期间).

Secondly, it has become more convenient to travel. We used to ride bikes or walk, but now we can take different transportation, such as the high-speed train, subway and plane. The development of the transportation provides more chances and ways for us to travel to different places. They can also save our time and money.

Thirdly, the shopping ways also changed a lot. In the past, people needed to go to markets or supermarkets to buy things. But nowadays, we can buy things or order food online, and the things we bought from any place in China and even around the world will be quickly sent to our home.

Lastly, the way of communication is also developing. In the past, letters are the only choice, but now people can chat or video chat on WeChat or QQ, make phone calls or send emails, no matter where they are. When we miss our family or friends far away, just take out our phones, then they can be in front of us!

It's happy to see the rapid development of science and technology in China. In the past, many new technologies were only invented by the western countries, but now China can also do it. With everyone's hard work, we Chinese are making it to the top!

For travelers, China in 1987 was a kind of place that could not be missed. In 1987, China was still using steam trains. Most people (probable) didn't think China could enter the age of the high-speed train in such a short time. It was (nature) for people from many countries to feel surprised. Bruce Connolly, photographer (摄影师) from Scotland, was one of them.

He came to China in 1987.then, he has traveled to many areas of China. He also has valued every important moment in his eyes by (take) photos. During his travel in China, Connolly found China was different from what he saw in photos. In the early years of his journeys, most Chinese people used to feel strange (see) foreigners, and avoided talking with them. But now, there are lots of foreigners living or traveling in (this) big cities. They are longer strange to Chinese.   

Another great change for Connolly is the wide use of new technologies. High-technology products(use) everywhere. People almost do everything with their smartphones. China has never given up and has become one of the (strong) countries in the world. Chinese people have used their wisdom to tell the world that they are going to have a bright future.
