When Mary entered the south Pole Penguin Research Lab, she saw her friend Tom gently stroking (轻抚) a penguin in his arms. As children of the lab scientists, Mary and Tom often observed the emperor penguins that were studied to understand how they adapted to extreme temperatures —insights that could aid human survival.
“We’re thirteen, Tom. It’s time to grow up and stop playing with the lab penguins,” said Mary as she started cleaning. “They’re research animals, not pets.”
“But the birds listen to me1” insisted Tom, his breath forming a cloud in the freezing air. “You’re just trying to be a penguin whisperer again,” Mary replied, shaking her head with a gentle smile. The penguins seemed playful as they walked, dove, swam and chased their live fish for sport before eating.
Suddenly , an alarm rang out and red lights flashed , signaling a problem. The kids rushed over to look into it. “It’s colder than before —there’s ice forming on the water,” noted Tom. Though always cold, Mary had never seen ice here before. She checked the habitat monitor and found that the temperature had gone down a lot. “The heater must be broken!”
Mary quickly sent a message to their parents’ research team, who were conducting outdoor studies. With the adults away, the kids would have to deal with the freezing conditions until help arrived.
Time dragged as Mary and Tom anxiously waited. The increasing cold caused them to shake. “I wonder what emperor penguins do in extreme cold, since they stay in the Pole all winter instead of going somewhere warmer,” asked Mary. “They huddle (挤作一团), ” Tom answered. “They huddle together tightly so that the birds in the middle will be warm enough.” “What about the ones on the edge?” Mary asked. “They push their way towards the center, and then move back out to the edge, and struggle back again. Scientists in the early 21st century recorded it.” He replied as he stared at the large crowd of the penguins in the lab.

___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________When my daughter. Rachel was 6 years old, we went to the local shelter, looking for a perfect cat. We liked all the cats we saw there, but we especially loved one that was black with a small white tip to her tail, like a bright star in the night sky. We brought her home and called her Starry.
Starry was lovely. At night when we watched TV, she would come into Rachel’s lap and comfortably stay there. Starry always got her face close to Rachel’s, ending her love with a gentle touch on Rachel’s nose. Sometimes I felt so jealous (忌妒的) of their love. Although I was the one who tank care of the cat, feeding and cleaning it, Starry was clearly Rachel’s cat. Finally, I came to love watching their close relationship
My little girl grew up and went to senior high school. Starry and Rachel were still close, though Rachel spent less and less time at home. starry spent most of her day sitting on the sideboard in the dining room, looking out of the window into the backyard. I loved seeing her as I passed by her, for her shiny black coat almost sparkled (闪烁) in the sunlight and the white tip of her tail looked bright against the shining black of her body.
One Sunday morning, early in November, Starry got out of, the room before we could stop her. When Rachel came home from school, she went into the room with a worried expression. “Where’s Starry?” she asked. When we told her we didn’t know, she led us outside with her. There was a black cat lying on the street.

She threw her school bag onto the floor and called out, “I’m home!” No answer. The house was silent. It sounded empty, but she knew it wasn’t. Her mum and dad were working upstairs.
Sara got a glass of orange juice, went into the conservatory (玻璃房) and sat down in her favourite chair. The garden was still in the dark afternoon. On one side, her mum’s garden was neat and tidy with boring short grass, boring straight flowerbeds and boring straight paths. But on the other side, Sara’s Nature Garden looked wild and exciting with big dead sunflowers and tall grasses.
“Nobody is interested in me. Mum and dad only think about their work,” she thought sadly.
Then she recalled: One month earlier, she learned in a magazine that many dogs were abandoned because their owners got bored with them; One hour earlier, she saw a cute dog wagging its tail and licking her friend’s face.
Sara knew today was special. Today things were changing. She couldn’t wait any longer. It’s time to talk to her parents.
So Sara got up from her chair and climbed all the way to the loft (阁楼). “Mum, I want a talk.” said Sara. “Just a minute!” Her mum clicked on the keyboard, took off her glasses and turned to her daughter. Sara coughed, took a deep breath, and told her mum that she wanted a dog. “No, Sara. That’s impossible,” her mum said firmly. Sara went to her father but got the same answer. She rushed into her room angrily and slammed the door shut.
Later, Sara’s mum knocked at the door and went in. “Darling, we know this is important to you. You can have a dog if you take the responsibility. But look at your Nature Garden, your school bag, your bedroom! What a mess! Do you think you can take good care of a dog?” said her mum.

5 . In our human-centric view, the ability to shoot ink or change colors may seem odd, but you know what’s really odd? Menopause (更年期). You can count species other than humans known to experience and outlive menopause on one hand. Only Oracs (虎鲸) and some whale populations have females that live long past their reproductive years to become grandmothers. But a new, landmark study confirms that at least one population of chimpanzees can now be added to the list.
The discovery comes as the result of 21 years’ worth of observing the Ngogo community of wild chimpanzees in Kibale National Park, Uganda. Studying urine from 66 Ngogo females, aged 14 to 67, showed that their hormone levels changed after approaching 50, confirming they were in menopause. Interestingly, 50 is also the age when many people begin to experience menopause. “It’s really cool to finally have that piece of the puzzle come into place,” says Catherine Hobaiter, a primatologist who was not part of the new study.
But Catherine points out that the Ngogo community lives in a chimp paradise: the resource-rich, well-protected Kibale National Park that also lacks leopards, their main predator. And because the Noggo community is found in the heart of the park, its only neighbors are other chimps — not humans who can expose chimpanzees to viruses that have devastated other communities. “The Ngogo population may be an outlier (局外人) when it comes to the rest of the species,” she cautions.
And there is a question concerning “the grandmother effect”, according to which a grandmother has a decidedly beneficial effect on her children and grandchildren. Chimpanzees do not form long-term pair-bonds and females leave in search of new communities when they reach maturity, which means grandmother chimpanzees likely don’t know who their grandchildren are in the same way humans or even orcas do. What they do after the menopause remains a question of interest. “And that’s all future work to be done.” said Catherine.

6 . High-resolution (高分辨率) satellite imagery has been used to map every single tree in Africa, showing a technique that could help improve the monitoring of deforestation (森林砍伐) across the world. Florian Reiner at the University of Copenhagen, Denmark, and his colleagues used images from sate lies to map canopy (树冠) across the entire African continent.
Modern sate lies usually catch tree canopies at a resolution of 30 meters — fine for measuring the size of forests, but less good at mapping individual trees. The satellite data Reiner and his colleagues used had a resolution of 3 meters, enabling the study to map all trees, including those not part of a forest.
The results suggest that 30 percent of all trees in Africa aren’t in a forest and instead are across farmland, savannah and urban areas. “Many countries in Africa lack thick forests, but have a lot of trees.” says Reiner. “These trees are extremely important to the local ecosystems, the people and the economy. By tracking every single tree, researchers can start to monitor how these trees are coping with climate change or whether they are sensitive to deforestation.” It could also improve the monitoring of reforestation efforts, which are growing in popularity as a way of removing carbon dioxide from the atmosphere.
“At a local level, being able to consistently monitor when and where trees are disappearing or reappearing can lead to more actionable insights,” says John Francis at the Alan Turing Institute in London.
“The study is a proof of concept rather than a map ready for immediate commercial use,” says Reiner. “It’s research work. It’s showing what could be done,” he says. But he is already working with colleagues to scale up the tracking approach to cover the entire global canopy: “We’re hoping that this will be seen as a way forward in monitoring tree resources.”

7 . Goldfish may seem like simple creatures swimming in a glass tank, but they possess a rather complicated navigation system, as discovered by researchers at the University of Oxford Led by Dr. Adelaide Sibeaux, the study aims to shed light on our understanding of how fish, and potentially humans, estimate distances using what could be described as an internal GPS.
Writing in the journal Proceedings of the Royal Society B, Sibeaux and colleagues report how they created a tank in their experiment with 2cm-wide black and white vertical stripes (条纹) on the walls, connected by similar stripes across the floor. The team trained nine goldfish to swim a set distance of 70cm and then return to their starting point when waved at. The experiment aimed to investigate how the fish would estimate this distance without any gestures, under different patterns.
Over multiple trials, the goldfish averaged a swim distance of 74cm, give or take 17cm, when presented with the vertical 2cm-wide stripes. However, when the stripe pattern was altered to either narrower vertical stripes, checked patterns, or horizontal stripes, the fish’s behavior changed significantly. Narrower vertical stripes led them to overestimating the distance by 36%, while horizontal stripes resulted in highly inconsistent estimations.
According to the researchers, the goldfish appeared to be using an “optic (光学的) flow mechanism” based on the visual density of their environment. They kept track of how frequently the vertical pattern switched between black and white to estimate how far they had traveled. The study suggests that different optic flow mechanisms are used by mammals, including humans, based on angular (有角度的) motion of visual features. The study implies that the use of visually based distance information could have emerged early in the evolutionary timeline.
“This study is novel because, despite knowing that fish respond to geometric information regarding direction and distance, we don’t know how they estimate distances,” Professor Colin Lever, although not involved in the study, said, “it’s exciting to explore fish spatial mapping because fish navigation evolved earlier and better than most mammals.”
1. Why did Dr. Adelaide Sibeaux conduct the study on goldfish?| A．To test the accuracy of goldfish’s internal GPS. |

| B．mammals developed flow mechanism long before goldfish |
| C．goldfish evaluated the distance with multidimensional visual information |
| D．visual density of the environment strengthened the locating ability of goldfish |

8 . “I like pigs,” Winston Churchill supposedly once said. “Dogs look up to us. Cats look down on us. Pigs treat us as equals.” Whether Churchill’s contemporary George Orwell also liked pigs is less clear. But he, too, surely saw something in them that was lacking in many domestic (驯养的) animals, for it was they who ended up running the show in his novel, Animal Farm. Pigs, then, are intelligent social creatures.
And, like all animals, they sometimes fight. Some pigs tend to be attackers; others tend to be victims. Who is what depends largely on weight. Among pigs, pounds mean power. The attacker might bite, kick or push the victim. Most conflicts end in seconds, but some last a minute or two.
In most animal species fights would be like that. However, many of the conflicts among pigs Dr Norscia, a biologist, observed had interested parties beyond the fighters. He therefore wanted to understand the role of these bystanders in solving conflicts—and what this says about pigs’ cognitive (认知的) abilities.
Since there was usually not enough time for a bystander pig to become involved in the heat of a conflict, though this did occur, Dr Norscia looked at what happened in the three minutes immediately following a fight. Sometimes, he found, the fighters reconciled with each other on their own. The more distantly related the fighters were, the more frequently this happened. Dr Norscia guessed that relations between close relatives are more secure to start with, so rebuilding friendly relations rapidly is less necessary for them.
On other occasions, however, a third pig stepped in. Sometimes this bystander interacted with the attacker, which reduced the number of attacks coming after. Sometimes, the bystander interacted with the victim. This appeared to calm the victim down, for it reduced anxiety-related behavior.
Social intelligence need not, though, be entirely selfless. Pigs are more likely to step in after a conflict if they are closely related to either the attacker or the victim. This is probably an example of kin selection (亲属选择), which favors the development of behavior.

Most of us never forget the person that was there for us in our darkest times. Apparently, penguins (企鹅) don’t either.
On a typical day, off the coast of a small Brazilian island, Joao Pereira de Souza headed out fishing. He was disheartened to find that an oil leak had polluted the waters. Staring out at the oily waves, he decided it was not a good day to fish. But walking on the beach that day, he found a struggling penguin, covered in oil and starving.
Joao took the penguin home, and spent a whole week gently cleaning it and nursing it back to health. He named it Dindim, a Portuguese word meaning “ice pop”. Dindim is a Magellanic penguin, a species known for living in the seas of South America. In order to breed (繁殖), they must return to Patagonia, 5,000 miles from Joao’s home.
After a week of rehabilitation (康复), Joao patiently took Dindim back to the sea and taught it how to swim again. When Dindim could swim quite well, Joao took it out into the sea by boat and dropped it off to encourage it to swim back to its home. But when he was back to shore, he found the penguin waiting for him. Joao made two more attempts later, but each time the bird would just return to Joao’s home. It seemed that Dindim had already formed a family bond with Joao and wouldn’t leave.
Joao had no choice but to keep the little creature. During the following months, Dindim would follow behind Joao to fish on the coast joyfully. Dindim also liked to lie on Joao’s lap, letting Joao give it showers, allowing Joao to feed it fish and to pick it up. Joao and his family enjoyed the company of Dindim. But deep inside Joao’s heart, he knew Dindim belonged to the wild. Gradually, the hot summer days witnessed the change of its new feathers. Was it time to say “goodbye”?

10 . “You should get a cat, ”my therapist(治疗专家)said. “A cat?” I couldn’t even look after myself. . I took a deep breath and carefully considered the idea of welcoming a feline (猫科的)friend into my life. This seemed like too easy a fix for the fact that I couldn’t leave the house without bursting into tears.
When my partner and I found Cinnamon, her adoption profile made her out as the perfect kitten. We filled out the paperwork and prepared for her arrival.
When she came home, it became increasingly obvious that Cinnamon didn’t understand “no”, “stop it” or “don’t do that”. She was the worst cat I’ve ever owned. I was beginning to doubt my therapist’s advice.
After visiting our vet, she concluded that Cinnamon just wanted our attention. She fought tooth and nail to get a bite of our meals. She’d fearlessly lick sharp knives when left unattended for a split second. Cinnamon stole my heart with her bravery and kept me busier than I’d ever expected.
We decided to start taking her for walks. I could barely leave the house before, but my heart couldn’t say no to Cinnamon. Cinnamon showed me what bravery looked like. She didn’t stop to consider every possible outcome of a situation; she simply went for it. If there was a dog at a park, she would run toward it. She jumped without knowing where she would land. She loved adventure. I found myself mirroring her behavior after a while, jumping out of bed without a second thought. I began to find the motivation to get out of bed in the morning.
Cinnamon unfortunately passed away after a medical accident. I’m no stranger to sadness or grief, but losing my pet so suddenly was the most confusing emotional experience I’ve had to date. She no longer wakes me up at 5 am begging for breakfast, but she’s still the reason I get up every morning.
Our time is often cut unpredictably, unmistakably short. It would be a shame to live life being anything less than brave and adventurous.
