1 . If a pancake could dream, it might long for legs so it could jump off your breakfast plate in pursuit of a better, unchewed life. But legs aren’t necessary for something as flat as a pancake to jump around. A group of scientists have designed a pancake-shaped robot that can jump several times per second and higher than seven times its body height. The new robot named Hop, which swiftly jumps without feet, is an important contribution to the soft robotics.
Many ground robots move by rolling or walking. But it’s more efficient for robots to jump over obstacles (障碍物) than to go around them. Although jumping can offer some robots a competitive edge, engineering that ability has been a challenge for robotics researchers. Some soft robots that store energy can perform a single impressive jump very infrequently. Some lightweight soft robots that don’t store energy can jump frequently but can’t jump high or far enough to successfully cross an obstacle.
For inspiration, the researchers looked to gall midge larvae (瘿蚊幼虫) that miraculously throw themselves across distances 30 times as long as their loglike bodies. A gall midge larva bends its body and squeezes the liquid in its body to one end, making it rigid (僵硬的). The accumulation of liquid builds up pressure, and releasing the pressure sends it soaring (飙升). The robot’s body doesn’t resemble (像) that of a gall midge larva, but it jumps like one. Its body is made of two small plastic bags printed with electrodes; the front bag is filled with liquid and the back one is filled with the same volume of air. The robot uses electricity to drive the flow of liquid, which causes the body to bend and generate force with the ground, resulting in a jump. And the air bag imitates the function of an animal’s tail, helping the robot keep a stable position.
While the robot is currently restricted to Earth, it might be right at home exploring another planet. If this is true, the researchers robot might jump over dusty rocks and large holes on the moon or Mars, going where no pancake has gone before.

2 . Primary and secondary school learners, university students, and guests were invited on Wednesday and were treated to a colorful celebration at the Confucius Institute at the University of Nairobi, to mark the beginning of the year of the dragon which officially starts on Saturday. The place featured beautiful decorations with red and gold colors and lucky symbols.
Visitors got an opportunity to participate in cultural experiences including painting, papercutting and pot throwing as well as experiencing Chinese cuisines like spicy hotpot, steamed stuffed buns (包子) , Chinese hamburgers, dumplings and barbecue among others. They were also treated to heartwarming performances including face-changing, lion dance, dragon dance, drumming, Chinese opera, Chinese songs and a talent show featuring Chinese traditional clothes as well as a mixture of Chinese and Kenyan fashion.
Leah Muthoni, a student at the University of Nairobi lauded the Chinese cuisines served at the event, especially noodles and dumplings. She also appreciated the decorations, drawings, pictures and performances. Similar feelings were also shared by George Mwita, another student from the University of Nairobi who greatly enjoyed the pot throwing game.
In his welcoming speech, Professor Stephen Kiama, the vice headmaster of the University of Nairobi who doubles up as the Kenya director of the Confucius Institute, hoped this year will be a good year of development because the Chinese dragon horns represent power and strength, while the drums represent courage and energy.
Kiama said the Confucius Institute at the University of Nairobi has achieved a lot since its establishment in 2005, including winning the Confucius Institute of the Year Award seven times and pioneering the establishment of the Bachelor of Arts in the Chinese language in Kenya. “Last year, with the joint efforts of the various parties and stakeholders we established the first bachelor of education in Chinese in Kenya and we admitted the first group of students,” he said. Kiama hopes that this year the Confucius Institute will gain more force with the blessing of power, courage and vitality from the year of the Chinese dragon. He said the Confucius Institute offers a good platform for cultural exchange between China and Kenya through events like the Chinese Lunar Year celebrations. Kiama hoped that the relationship between China and Kenya would further be strengthened by the blessings of the year of the dragon.

3 . When my school offered the opportunity to take part in a School Challenge, I didn’t hesitate to sign up for the initial meeting.
Of course, it was not a case of simply signing up and paying the money.
We had been warned that our trip would not be a holiday and that things would not always go to plan. We certainly experienced the difficulties during the trip.
My School Challenge trip influenced my life in so many ways. It gave me a taste for independence and adventure, and certainly made me want to travel more.
A.This had to be raised by us to fund the trip. |
B.Despite the obstacles, it was a truly amazing trip. |
C.Above all though, it has made me realise how easy my life is. |

4 . By the late 1960s, painter Harold Cohen had represented Britain at important festivals with his oil paintings and was seeking a new challenge. “Maybe there are more interesting things going on outside my studio than inside it,” he thought. Cohen turned from the canvas (画布) to the screen, using computers to find new ways of creating art. In the late 1960s, he created a program named Aaron. It was the first artificial intelligence software in the world of fine art, and Cohen first presented it in 1974 at the University of California, Berkeley.
Now, with AI filling the headlines, a new exhibition called “Harold Cohen: Aaron” at New York’s Whitney Museum of American Art draws attention to Cohen’s pioneering work. The Whitney is offering something deeper than most previous Aaron exhibits: a real-time experience, in which visitors can watch the software produce art.
Cohen provided Aaron with all sorts of knowledge: about basic objects, physics, and fundamental techniques of drawing. Aaron uses the given knowledge to follow instructions, complete tasks, and make decisions like human beings- a very different approach from today’s generative AI art programs.
The Whitney is displaying two versions of Cohen’s software, along with the art that each of them produced before Cohen died. The 2001 version, Aaron KCAT, generates images of figures and plants and projects them onto a wall more than ten feet high, while the 2007 version produces jungle-like scenes. The software will also create art physically, on paper, for the first time since the 1990s. “It is absolutely thrilling,” said Christiane Paul, the museum’s director of digital art, “to have one of those remarkable treasures of digital art in the collection.”

5 . As a high school student, you’re likely used to learning through reading textbooks.
To practice experiential appreciation, you can start by getting involved in hands-on activities related to your subjects. They will provide a firsthand understanding of the concepts you’re studying, making learning active and meaningful. So, try joining a sports team, picking up a paintbrush, or taking part in a local charity event.
As you dive deeper, immerse (沉浸) yourself fully in the surroundings and activities. When you’re in nature, don’t just look around.
Experiential appreciation transforms learning from a task to be completed into a journey to be treasured.
A.It extends learning beyond textbooks. |
B.These activities bring learning to life. |
C.Mind the impact of your actions on the environment. |
D.Instead, activate your senses for a stronger tie with it. |
E.Take your experiences further by reflecting on them. |
F.Textbooks offer a systematic introduction to essential concepts and principles. |
G.Now consider expanding your learning from just reading to actively participating. |
6 . I’ve loved to sew all my life. I started sewing clothes for my dolls when I was 7. My mother showed me how to stitch with a needle and thread, and it was my favorite pastime when it was too cold and snowy to play outside. As a teenager, I began to design and sew my own outfits. I cut out paper patterns to construct dresses and skirts, and I’d sit at the old sewing machine for hours.
In my late 20s, I began to buy used and vintage clothes to upcycle and refashion. My favorite places to buy vintage clothes are thrift shops (旧货店) and church rummage sales (教堂义卖).
However, about 10 years ago, when I was ripping out the silk lining (内衬) from a beautiful long blue evening dress, I stopped. There was a hidden pocket in the front that I failed to notice as I merrily ripped at the seams. I pulled out an old photo of a young woman wearing the very same blue evening dress. A long silver chain necklace hung gracefully down the front of the dress, and she was holding a black purse. She had a soft smile, and she looked to be in her early 20s.
Somebody else wore this dress many years ago. Who was she? Did she wear it to the theater? To a fancy dinner party? And I was now tearing it apart. I felt guilty.
I mentioned my concerns and guilt to my daughter. She said, “Mom, you should be proud of your upcycling and your sewing creations. You are keeping clothes out of the landfill (垃圾填埋场), and you’re creating new fashions. Consider it a bonus (意外收获) if you find objects in the pockets. The clothes are talking to you!”
I decided to pay homage to this upcycling discovery -and the many others I’ve found over the years — by displaying them on a bulletin board in my sewing room. These discoveries have made me enjoy refashioning and upcycling clothes even more. But I have learned to be a little gentler when I rip seams open with my scissors, and I approach pockets more carefully.

10 . I’d entered into another one of those busy periods in life that we all have from time to time. It is those times when in addition to the usual hustle and bustle of life a dozen other things suddenly show up that need to be done right away as well.
After grabbing what I needed I walked through the corridor containing mostly little things.
It was a little saying on a cheap wood square no bigger than my hand with a string attached to hang it on the wall. In cursive writing along the top it said: “SLOW DOWN &” while below it in big block letters were the words: “ENJOY TODAY”.
I just stood there and read this message over and over. As I did, I felt a calm settling over my soul.
In this crazy life, we all need to remember to “SLOW DOWN & ENJOY TODAY.”
A.Finally I decided to pay the dollar it cost. |
B.What’s more, we need to remember to love. |
