3 . I like challenges, but this one was almost too difficult. I had begged Mom to take me on a completely new adventure for my sixteenth birthday. Now, here we were, just Mom and me with our guide, Milo, standing on the shore of Lake Arenal in Costa Rica.
Milo helped us onto our horses. Getting on the back of my horse was difficult, but controlling it was a little easier. We started on our ride. The guidebook said we would cross three rivers. As we tried to go through a gentle stream, I asked hopefully, “Is this the first river?” “I don't think so, Katie,” Mom said.
Soon enough, we came to a real river. I felt sick to my stomach when I saw that the far shore was half a football field away! The four-foot-deep river flowed over large rocks. So much for dry shoes or jeans.
After two more rivers, the path got steeper and muddier. The rainforest was splendid and absolutely beautiful. But I wondered whether my horse could keep its balance in knee-high mud. Three frightening hours later, we came to a corral (畜栏). I wondered whether we were stopping. To one side was a wonderful view of the lake and volcano, and to the other, a brightly painted restaurant. “OK,” I laughed nervously. “That was frightening, but I'm so glad we did it! ”

4 . A team at a US university trained an AI tool to examine 60,000 fingerprints to see if it could work out which ones belonged to the same individual. The researchers claim the technology could identify, with 75-90% accuracy, whether prints from different fingers came from one person.
But they are not sure how it works. “We don’t know for sure how the AI does it,” admitted Prof Hod Lipson, a roboticist at Columbia University who led the study.
Graham Williams, professor of forensic science (法医学) at Hull University, said the idea of unique fingerprints had never been set in stone. “We don’t actually know that fingerprints are unique,” he said. “All we can say is that as far as we are aware, no two people have yet to show the same fingerprints.”
The results of Columbia University’s study could have the potential to impact both biometrics and forensic science.
If, for example, an unidentified thumb (拇指) print is found at crime scene A, and an unidentified index (食指) fingerprint at crime (犯罪) scene B, the two could not currently be forensically connected to the same person — but the AI tool could be able to identify this.
The Columbia University study will be published in the journal Science Advances on Friday. But a pair of twins in Cheshire might be ahead of everyone. Their grandmother Carol told the BBC her two grandchildren can open each other’s iPhones using their own fingers.
“They showed me on Christmas day,” she said. “We were told they were identical when they were born but I can tell the difference between them as they’ve got older.”She claimed that her grandchildren can also bypass the handsets’ facial recognition feature.
Fingerprints are formed before birth. Research published last year suggested the genetic process behind them may be similar to the way animals like zebras and leopards get their markings.

5 . Alongside her impressive musical career, Leona Lewis is also the owner of a vegan (素食主义的) coffee shop, Coffee And Plants. She has great enthusiasm for the coffee shop and reveals the drink flavors that they’ve been working on lately. “We’ve just rolled out our new pumpkin drink at the coffee shop. It’s called Pumpkin Pie, and it’s really good! We use all real pumpkin puree, not flavored syrup.”
Coffee And Plants is a real passion project for Lewis, being fully plant-based. She has a long history of animal activism (行动主义), starting with going vegetarian (素食者) at the age of 12 after going on shopping trips with her mum and seeing protesters with animal testing signs. “I was so upset, I said, ‘Mum, I have to help the animals’,” she says. “That became my mission as a kid, and it’s fed into every aspect of my life.”
Her animal activism grew alongside her fame: in 2011 she supported a campaign to ban the use of wild animals in circuses, and in 2013 she released a cruelty-free makeup line with The Body Shop. When it came to opening a coffee shop, making it plant-based was a no-brainer.
“I wanted it to be plant-based because I’m plant-based,” she says. “I would often go into coffee shops and see milk cartons piled up high and think, how many cows are being milked for this? The dairy industry and mass farming—it’s so cruel and harms the environment too.”
Environmental awareness is also at the heart of Coffee And Plants, with all cups being recyclable. But ultimately, Lewis is hoping for a more widespread mindset shift. “What we really try and get people to do is actually bring in their own bottles to refill, or we encourage them to sit in and have a coffee in a cup instead,” she explains. “We need a mindset shift where we start to think, OK, we shouldn’t really be using stuff that just goes in the bin.”

6 . When Senait Lara, a 28-year-old video producer, was questioned by her friends about her lack of communication in their group chat, the blames were as follows: she only caught up every few days; when she did, it was hardly an interaction — Lara spent time “liking” messages instead of responding with words and sometimes she would never respond at all. Lara didn’t deny it. She knew she sometimes preferred to completely avoid her phone rather than deal with a large number of requests. Actually, in person, Lara felt comfortable talking with people, but when communication came down to a text message or an email, she wanted to tap out.
While social media and messaging apps keep us more connected to each other, many younger users are finding themselves tired out from receiving constant notices and carrying on conversations that can last all day. The after-effect? Delayed responses, forgetting to get back to someone entirely, and a need for frequent breaks.
In fact, a 2023 study exploring the effects of information overload and online conversation dynamics (动态) found that “over-exposure to information can suppress the possibility of response by overloading users.”
Smartphones have quickly changed into handheld storage units for our conversations, thoughts, music and everything else. That shift to feeling constantly attached to our phones as if they were a limb relates to the burnout, says psychologist Emily Balcetis.
As the pressure to be online and always available continues to grow in our society, in-person interactions provide far more real communication than digital ones. From body language to eye contact and all the other social clues that exist in real life that aren’t available in a text message, it’s far easier to be present when you’re face-to-face. As Balcetis notes, “At the end of the day, I think what we’re looking for is not more ways to stay connected, but higher quality ways to be connected.”

7 . If you find yourself embracing the thrilling chaos of completing tasks at the last minute, congratulations — You are not alone! According to a survey, 20% of U.S. adults procrastinate (拖延) at home, at work, in relationships, and more. Another survey found that 88% of people procrastinate at least one hour a day.
Sounds alarming? As it turns out, if you’re feeling stressed, you may be more likely to procrastinate. Essentially, our brains are structured to approach tasks we find enjoyable and avoid those we are afraid of. Our limbic brain (边缘大脑), the emotional part of our brain, is screaming, “Let’s do anything but that stressful thing!” while our prefrontal cortex (前额叶皮层) is the CEO of our brain, setting the goals, making a plan, and ensuring we stay on track. CEO vs. Drama Queen Brain — who will win? Actually, there do exist chances when our limbic brain overrides that prefrontal cortex message.
Then there’s the burst of energy we often get when we’re up against a deadline, which leads to a reward pathway within our brains and sets the foundation for procrastination as a habit. When you race to the end and get to the goal finally, your previous stress is gone and you almost get in that pattern of “See, I work better under pressure!”
So, how to beat procrastination? Well, you need to retrain your brain to cope with the stress. One trick is to take periodic breaks (reward) to refocus your attention on the task. Ever heard of the Promodoro Technique? It’s about working for 25 minutes and resting for 5. During those breaks, forget about brain-burning activities — try relaxing techniques such as meditation or yoga instead. Another trick is to “eat the frog” first thing in the morning, or tackle the most difficult and stressful task of the day, as was once said by Mark Twain.
1. Why are the two surveys mentioned in the first paragraph?A.To warn the readers. | B.To introduce a concept. |
C.To present a phenomenon. | D.To make a comparison. |
A.We are born to prefer what we like and avoid what we fear. |
B.The limbic brain is under the control of the prefrontal cortex. |
C.We are more likely to burst when getting close to the deadline. |
D.Failing to complete a task can lead to habitual procrastination. |
A.Force the brain to focus. | B.Take a break regularly. |

8 . Artificial intelligence(AI)models have long surpassed (超过) just creating text responses and images. Now, with only one sentence, OpenAI’s latest text-to-video model, Sora, can turn your words into video with good visual quality while faithfully following your content instructions.
Sora is said to perform better than many other existing models with similar functions. The Al model can create video at suitable aspect ratios (屏幕高宽比) for different devices, such as both widescreen videos and vertical videos that we usually see on social media. It also lets users quickly test out content in lower quality before making the high-quality version, which helps speed up output.
Aside from this, its ability to present videos in a realistic and smooth manner is amazing. Sora can create detailed scenes with several characters, scientific types of motion, and accurate subject and background details while generating multiple shots with a single video. Beyond the user’s requests, it also understands how these elements exist in the real world. For example, reflections in the water changes as a woman walks by.
Sora’s performance wouldn’t be possible without its helpful assistant, ChatGPT, which transforms simple sentences into detailed descriptions. improving the accuracy of output according to the user’s prompts (提示语).
However, the current model isn’t perfect. It may have trouble accurately showing how things move in a complicated scene and might not get how one action leads to another. For example, if someone eats part of a cookie in a Sora-made video, the cookie might not look like it’s been bitten into. The model might mix up directions like left and right, and find it hard to describe events in the right order.
As of February, Sora is still in the testing stage of development. OpenAI is now inviting cybersecurity professionals to make random attacks on Sora’s system, aiming to test the model’s possible weaknesses and risks. Sora has also been open to some visual artists, designers and filmmakers. Their feedback (反馈) will assist OpenAI in enhancing the model to better serve creative professionals.

9 . It’s a sunny March afternoon at Winchester Village Elementary School in Indianapolis, and teacher Natasha Cummings is leading her class in a brand new lesson. It’s the first time she’s teaching it and also likely the last. The second graders audibly take a short quick breath when Cummings explains the day’s activity: They’ll be simulating(a total solar eclipse (日全食) using the real sun, an inflatable globe and a moon made out of a play dough ball mounted on a stick.
On April 8, a narrow strip of North America will experience a total solar eclipse, in which the moon entirely covers the sun, darkening the sky so that only the sun’s corona, a ghostly white ring, will be visible. Indianapolis is one of several cities in the path of totality. The last time that happened was over 800 years ago, and it won’t happen again until 2153. For many of Cummings’ students, this event is a once-in-a-lifetime opportunity. Cummings hopes learning about and witnessing the eclipse will inspire her students, and get them excited about science. It’s an experience she expects them to remember for the rest of their lives. “This is a story you’re gonna be able to tell,” she reflects before class.
In a grassy area outside the school, Cummings’ eclipse simulation begins: Students take turns holding the inflatable globes, and casting a shadow with their play dough moons. Cummings directs them to aim the shadow over the spot on the globe where Indianapolis would be. It’s a little chaotic, but the students quickly figure out how to properly position the moon’s shadow over their hometown.
Thomas Hockey, a professor of astronomy at the University of Northern Iowa, says he didn’t learn about solar eclipses when he was in grade school. He thinks the fact that elementary school teachers like Cummings are now teaching about them is an indication that science education has improved since he was a child. "Science is not done by old, gray-haired people in lab coats, necessarily. Citizens can participate in it. It’s not a magic black box; it’s all around us,” Hockey says.
