（24-25高三下·重庆·阶段练习）A while back, I met a capybara (水豚) named Pisuke in Tokyo. I sat on a couch next to him, stroking his straw-like fur and the pinkish skin beneath, thick as sailcloth. His ears looked like mushrooms, twitching occasionally. I scratched under his chin, and he half-closed his eyes. “How is this animal even real?” a friend asked after I showed her a selfie. My connection to them predates the internet craze.

The capybara’s unreality is partly why it has such a strong fan community. The past years have seen the rise of capybara on TikTok and Instagram. If you’ve followed them on social media, you might know they get hiccups, carry large oranges on their heads, and allow birds to clean their fur. After my half hour with Pisuke, I felt immersed in a deep well-being. Time flowed differently, and my vision softened. The world felt pure and unaggressive. We were all living our lives as the giant creature that never meant anybody any harm.

In a world of conflict, instability, and fast-paced culture, people seek comfort and peace. It’s led them to the meditative, wholesome faces of the capybara.

“One misconception is that they’re so cool,” Somma said. The capybara is a predator (捕食者) in its native habitat, with predator reactions, especially when cornered for humans hunt them for meat and skin. To avoid scaring it, I squatted and moved toward it slowly. Its flightiness reminded me of childhood bullying, my constant need to find an exit when surrounded by overly enthusiastic people. I realized the capybara represent a dilemma I knew too well: a friendly creature always afraid of attack. Do we love them because we, too, feel trapped in a world that encourages hyper-socializing yet rewards us with existential anxiety?

I asked Somma why people like me are drawn to capybaras. “They’re sweet animals,” she said. “You can connect with them without physical contact.” I was astonished by how well the writers and directors portrayed the capybara in the film: mostly sleeping, eating grass, and getting along with other animals. When scared, it withdrew. An unlikely hero, but a perfect one for our times.

163．What is a key reason for the capybara’s popularity?

A．Their gentle nature. B．Their lively behavior.

C．Their high intelligence. D．Their endangered status.

164．How did the author feel after interacting with Pisuke?

A．Bored but peaceful. B．Immersed and calm.

C．Restless and unaggressive. D．Energetic and hyper-social.

165．What does Somma emphasize about capybaras?

A．They are always cool. B．They are top predators in their habitat.

C．They reproduce better in a stable world. D．They preserve natural tendency of predators.

166．Why does the author consider the capybara “a perfect hero for our times”?

A．They defend themselves when threatened.

B．They avoid physical contact to protect their emotions.

C．Their quiet, withdrawn existence mirrors modern anxieties.

D．They have hyper-social confidence while physically weak.

（24-25高三下·重庆·阶段练习）Stories written by the latest version of ChatGPT were nearly as good as those written by human authors, according to new research on the narrative skills of artificial intelligence. But when people were told a story was written by AI — whether the true author was an AI or a person — they rated the story poorly, a sign that people distrust and dislike AI-generated art.

“AI is good at writing something that is consistent, logical and coherent. But it is still weaker at writing engaging stories than people are,” said Haoran “Chris” Chu, Ph.D．, co-author of the new study. Chu and his co-author, Sixiao Liu, Ph.D．, published their findings in the Journal of Communication.

The researchers exposed people to two different versions of the same stories. One was written by a person and the other by ChatGPT. Survey participants then rated how engaged they were with the stories. To test how people’s beliefs about AI influenced their ratings, Chu and Liu changed how the stories were labeled. Sometimes the AI story was correctly labeled as written by a computer. Other times people were told it was written by a human. The human-authored stories also had their labels bartered.

The surveys focused on two key elements of narratives: counterarguing — the experience of picking a story apart — and transportation. “Transportation is a very familiar experience,” Chu said. “It’s the feeling of being so engaged in the narrative you don’t feel the sticky seats in the movie theater anymore. Because people are so engaged, they often lower their defenses to the persuasive content in the narrative and reduce their counterarguing.”

While people generally rated AI stories as equally persuasive as those written by humans, the computer-written stories were less effective at transporting people into the world of the narrative.

“AI does not write like a master writer. That’s probably good news for people like Hollywood screenwriters — for now,” Chu said.

159．What does the author highlight about AI-generated stories in paragraph 1?

A．They are lacking in coherence. B．They are discriminated against.

C．They show great narrative skills. D．They rely partly on human work.

160．What does the word “bartered” underlined in paragraph 3 mean?

A．Rated. B．Attached.

C．Removed. D．Exchanged.

161．What can we infer about counterarguing and transportation?

A．They work in conflict with one another.

B．They are both need improving for authors.

C．They increase the persuasive power of a movie.

D．They apply to understanding different narratives.

162．What is Chu’s view on AI writing for Hollywood movies?

A．It is unrealistic at present.

B．It will be a win-win story.

C．It is a well-established fact.

D．It will prove fruitless anyway.

（24-25高三下·重庆·阶段练习）It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without wearing headphones. In a new development in audio engineering, a team of researchers led by professor Yun Jing, in the Penn State College of Engineering, has precisely narrowed where sound is heard by creating specific sound zones, called audible enclaves (声音飞地). In an enclave, a listener can hear sound, while others standing nearby cannot, even if the people are in an enclosed space, like a vehicle, or standing directly in front of the audio source.

In a study published today (March 17), the researchers explained how emitting two ultrasonic beams (超声波束) create audible enclaves, where sound can only be heard at the precise meeting point of two ultrasonic beams.

“We use two ultrasound devices combined with a special surface which emit self-bending beams that meet at a certain point,” said the main writer Jing. “The person standing at that point can hear sound, while anyone standing nearby would not. This creates a privacy barrier between people for private listening.”

By positioning the surfaces in front of the two ultrasound devices, the ultrasonic waves travel at two slightly different frequencies along a curved path until they meet, researchers explained.

Neither beam is audible on its own — it is the meeting of the beams together that create an interaction, which generates audible sound. The beams can bypass obstacles, such as human heads, to reach the meeting point.

Researchers tested the system in a common room with normal echoes, meaning the system could work in a variety of environments, such as classrooms, vehicles or even outdoors. “We essentially created a virtual headset,” Zhong said. “Someone within an audible enclave can hear something meant only for them — enabling sound and quiet zones.”

For now, researchers can remotely transfer sound about a meter away from the intended target and the sound volume is about 60 decibels, equal to speaking volume. However, the researchers said that distance and volume may be able to be increased if they increased the ultrasound intensity.

155．What is the main goal of the new sound technology?

A．To replace car radios.

B．To block all sounds in a room.

C．To make music louder for everyone.

D．To allow private listening without headphones.

156．How do the audible enclaves generate audible sound?

A．By adjusting frequencies.

B．By bypassing obstacles.

C．By reflecting sound waves off a curved surface.

D．By sending particular beams to their meeting point.

157．What is a current limitation of the technology?

A．It requires multiple ultrasound devices.

B．Its effective range is roughly one meter.

C．It cannot work in environments with normal echoes.

D．The sound volume is too low compared to headphones.

158．What can be inferred about the technology’s future development?

A．Reducing production costs is essential.

B．Beam paths need frequent adjustment.

C．Higher ultrasound intensity may extend range.

D．All public audio systems will be replaced.

（24-25高一下·云南昆明·期中）Here are some enjoyable UK races to choose from this month.Winter Sugar Loaf

Abergavenny, Monmouthshire, 2 November

This fell race north of Abergavenny costs just £9 to enter, but don’t wait too long if you want to join — only 125 runners can take part. You’ll be following a largely unmarked path to the top of the Sugar Loaf and since the weather may be terrible, full equipment is required. It may be only 9.6 km in length, but there are some seriously steep (陡的) bits on this tough race.fellrace.com

Wendover Woods 50

Wendover, Buckinghamshire, 9 November

There are nine aid stations with lots of snacks, so you’ll always have food nearby. You’ll need them for this 50-mile race. The hills never end and by the time you reach the finish, you’ll have climbed some 3,000 m. But the paths are pretty well built.centurionrunning.com

Conwy Half Marathon

Conwy, Caernarfonshire, 17 November

This race heads north out of Conwy towards Llandudno and that big rock sticking out into the sea-hat’s Great Orme, and you’re running around it rather than up it. But the path around it still includes some punishing climbs. It’s just one of many beautiful sites along the way.rumwales.com

Tadcaster 10

Tadcaster, Yorkshire, 23 November

The path is a straightforward loop on closed roads that are mostly flat. With the first and last few kilometres in the town of Tadcaster, you’ll get a nice mix of support from locals and quiet time in the countryside.racebest.com

（24-25高一下·云南昆明·期中）When I call Sherry Pocknett for the first time, she’s on her way out the door to pick mushrooms. But then she invites me up to her restaurant, Sly Fox Den Too. Pocknett is one of the people best known for making indigenous (土著的) foods. Her restaurant, opened in 2021, is her own way of using her people’s knowledge to feed Americans today. And she hopes the menu shows the width and depth of indigenous foods.

Pocknett’s menu is based on a simple idea: “The food I grew up with,” she says. She cooks what’s local and what’s in season. I watch Pocknett prepare venison (鹿肉) topped with onion (洋葱) rings, which, she admits, aren’t exactly a deep-rooted tradition; they’re “from a mix” , she says, “but I just love them.”

Pocknett works on a reduction of beach plums (海滨李) to pair with the venison. To wash it all down, there are pots full of iced tea made from boiled sassafras (檫树) roots. Even if you’ve never heard of this common North American tree, you probably know the taste — it was long the key part in root beer. The meal recreates foods from a traditional festival in 1621.

Restaurants specializing in Native American food are not so common — but a small number of indigenous cooks with great love are working to raise their profile (形象). Owamni, a restaurant in Minneapolis focuses on indigenous food, won the James Beard Foundation Award for Best New Restaurant in 2022. The Sioux Chef is a company working on indigenous foods, too. Its owner Sean Sherman and his team are working tirelessly toward the day when “people will find an indigenous restaurant easily in America, experiencing all the richness of the varied original American cultures.”

148．Which can best describe Pocknett’s offerings?

A．Seasonal. B．Plant-based. C．High in price. D．Limited in variety.

149．What does the underlined phrase “wash it all down” probably refer to?

A．Cooking the food with care. B．Picking all the plums on the tree.

C．Getting the food down to the stomach. D．Washing the plums completely before cooking.

150．What can we infer about Pocknett from paragraph 3?

A．She leaves food for the locals.

B．She is very choosy about what she eats.

C．She draws inspiration from local historical traditions.

D．She is known for mixing indigenous and international tastes.

151．What does the author want to show by mentioning two restaurants in the last paragraph?

A．The special culture passed on by famous Americans.

B．The growing recognition and efforts of indigenous cooks.

C．The cut-throat state of national cooking competitions.

D．The popularity of indigenous restaurants outside America.

（24-25高一下·云南昆明·期中）The Mountain Bongo (a type of antelope) has been driven to near extinction, according to the IUCN (International Union for Conservation of Nature). Ecologist Mordecai Ogada says, “It can only be found in the wild in Kenya, highly endangered, and that is why protecting this species is important.”

The populations of the animals have been greatly reduced. The animals have been hunted for their meat and their prized coat, skulls, and horns. Human-wildlife activities, especially the sharing of grounds with livestock (家畜), also led to the spread of diseases.

Some were traded to zoos in the United States and efforts to save the animals have depended on returning them to Kenya. At one time, there were only 18 of these creatures left in captivity (圈养) there. They were sent back to Kenya in 2004 to breed (繁殖) them and re-establish the Mountain Bongo in their natural area. But it has been a slow process.

“So, the bongos that are coming back from zoos need a very long time to be able to get used to the wild environment again and it takes several generations,” explains Philippe Cauviere, chief executive officer at Mount Kenya Wildlife Conservancy. “And that is why it has taken such a long time to get where we are today. We’ve had more than 70 births.”

To support the recovery of the species in the wild, the government agency, Kenya Wildlife Service, together with Mount Kenya Wildlife Conservancy, set up the Mawingu Bongo Sanctuary as part of the National Mountain Bongo Recovery and Action Plan 2019-2023. The sanctuary is on the slopes (坡地) of Mount Kenya. There are plans to set free 25 Mountain Bongos in this protected area. This will help the rewilding of the animals as well as reintroducing them into their original habitats.

“Finally what needs to be done to save the Mountain Bongo is their habitat has to be protected-these are the highland forests. I think the goal here is not captivity but to increase wild populations and rewild them and reintroduce them into this country,” Ogada says.

144．What is discussed in paragraph 2?

A．Suggestions on how to protect the Mountain Bongo.

B．Great progress on saving the Mountain Bongo.

C．Reasons why the Mountain Bongo is important.

D．The reduction in Mountain Bongo populations.

145．Why has the rewilding process of the Mountain Bongo been slow?

A．There is the problem of habitat loss. B．There are not enough research funds.

C．They need time to adapt to the wild again. D．They are under threat from other species.

146．What should be done to save the Mountain Bongo according to Ogada?

A．Making the Mawingu Bongo Sanctuary larger. B．Protecting their highland forest habitats.

C．Making more laws to prevent hunting. D．Keeping them in zoos.

147．What is the best title for the text?

A．Kenya rushes to protect endangered antelope.

B．Rewilding the Mountain Bongo seems impossible.

C．Zoos are getting more effective at wildlife protection.

D．The changing environment is challenging the Mountain Bongo.

（24-25高一下·云南昆明·期中）While AI’s influence on various industries like healthcare is widely discussed, the legal profession has received less attention. In fact, the business of law is well-positioned to achieve the highest ROI (投资回报率) from using AI.

Law firms (公司) are seen as traditional but most have used machine learning for years. In the business of law, AI-driven time and cost savings are typically very high. The benefits have led to the appearance of a new type of law firm-AI-centric (aka AI-native) law firms. Staff (全体职工) and lawyers at AI-native firms make the most of AI for various tasks such as research. AI-native law firms also use AI to service customers who require personalized treatment.

Every day, junior associates (初级律师) need to work fast and correctly, yet never miss anything important. The work can tire them, leading to mistakes. AI can do in seconds what takes days for a junior associate. Speed gives AI a great role in the legal field, with ROI well beyond the “traditional” 10 to 20 percent. AI-centric firms can grow without increasing the support staff. Wherever AI reduces costs, it frees up funds for marketing development. AI makes marketing communications faster and easier for law firms, as it does for other businesses.

AI’s positive effect on work satisfaction is often underappreciated. According to a 2023 Thomson Reuters survey, lawyers at AI-native firms often send repetitive tasks to AI. Support staff and junior associates become, in effect, supervisors (监督人) of AI. This truly improves work satisfaction.

Are law firms jumping on board and going AI-native in large numbers? Surprisingly the answer is no. According to another survey 60% had no plans to use AI. That’s good news for the other 40%. The legal profession is among the industries achieving the best ROI from the use of AI. Law firms should “get it” and enjoy greater growth and profitability.

140．What makes the new kind of law firm special?

A．The high ROI. B．The effective use of AI.

C．Focusing on AI cheating cases. D．Providing personalized treatment.

141．What is paragraph 3 mainly about?

A．Why AI is helpful to law firms. B．What high ROI means to law firms.

C．When AI will take over traditional law firms. D．How law firms deal with marketing challenges.

142．What did the Thomson Reuters survey find?

A．The legal profession often has high profitability.

B．Support staff are very important to a law firm.

C．AI contributes to increasing job satisfaction.

D．Law firms are leading in using AI.

143．Which of the following will the author probably agree with?

A．It’s time for law firms to go all in on AI. B．Safety is the major concern for law firms.

C．AI technology should grow alongside the law. D．Law firm can be new and old at the same time.

（24-25高一下·广东深圳·期中）The owner of a business is hoping to help save lives by offering adaptive swim lessons to children and adults with disabilities. The classes are taught by Julie Cordiero and her staff at Jr’s Swim School. Cordiero says she came up with the idea when she saw a specific need while teaching swim lessons at another school in 2017.

“The number one cause of accidental death among kids with autism (自闭症) is drowning (溺水), and in Arizona, there are pools everywhere.” said Cordiero. “Autistic children are easily attracted to large bodies of water. so they might not have safety skills when they want to jump into a body of water.” Cordiero added

Cordiero’s classes teach survival skills, balance and strength to children with special needs in a personalized way. “We see a lot of different sensory levels and needs at our swim school and our staff really does have the training strategies to work through those appropriately,” said Cordiero. Cordiero also has regular meetings with students’ families, and after each meeting. Cordiero will adapt each swim lesson to help set each student up for success.

Ann Snyder says her son James is nonverbal (不会说话的) and has loved the water now more than ever since he started taking classes at Jr’s Swim School. Aimee Craumer, whose 11-year-old daughter Macayla takes classes, says safety boundaries are taught repeatedly and that gives their family peace of mind.

Instructors at Jr’s Swim School are devoted to helping those with disabilities become more confident in the water, and they use nontraditional teaching methods to help students overcome the most common barriers they see during swim lessons. “We want to create something that is unique and really suits a population that is just as worthy of learning a lifesaving skill as the rest of the population. A lot of passion and patience goes into what we do but we are making a huge difference and that is a good feeling,” said Cordiero.

136．What issue does Cordiero aim to address through adaptive swim lessons?

A．Anxiety related to water B．Lack of interest in swimming

C．Drowning risks for disabled people. D．Inaccessibility of swimming facilities.

137．What does Jr’s Swim School’s way of teaching stress?

A．Students’ physical fitness B．Students’ competitive skills

C．Individuals’ family conditions. D．Individuals’ personalized demands.

138．How might students’ parents feel about their children’s participating in the classes?

A．Relieved and satisfied. B．Proud but concerned.

C．Surprised and regretful. D．Pleased but doubtful

139．What can be learned about Jr’s Swim School from the last paragraph?

A．It highlights students’ own passion. B．It values the openness in teaching.

C．It teaches students to pass on kindness. D．It encourages children to become athletes

（24-25高一下·广东深圳·期中）Oil leaks at sea create risks to sea life and people, and attempts to remove that oil tend to be challenging and costly and often fail to achieve desired outcomes. But scientists in China have found a new way to clean up that sticky pollution: cork (软木).

Past research has shown that cork could collect oil, but the process is too slow to seem promising, the problem of which is that oil is highly sticky, or thick. But oil gets thinner when it warms up, allowing it to more easily get into cork or stick to cork’s surface.

Yuchun He, leader of the research team, said they had been using lasers (激光) to carve patterns into wood, but they’d never tried carving cork before. When they did that, they found something unexpected: The cork darkened, suggesting it might be photothermal, which might allow the cork to be warmed up in light. And scientists assumed that tiny holes created by the laser might help the cork store more heat, the warmth of which can attenuate nearby oil, making it easier for the cork to adsorb (吸附) oil.

The treated cork is an example of something that is adsorbent, which can clean up a leak because the oil now sticks to its surface. Using cork materials as adsorbents can better separate oil and water, allowing people to recover some of the oil so that it can be used. Oil leaks can kill sea life, and today, to clean up a leak, sailors often remove oil from the water’s surface as they apply some harmful chemicals that aim to break down the oil.

The tests took place in a lab, so cork cleanup will need to be tested at sea to see if it works in real-world conditions. “After cork is harvested from a tree, it grows back in about 10 years. So far, no one has tested whether it can be reused. To my knowledge, there are almost no truly reusable oil-adsorbing materials. But even if cork isn’t either, it may still offer a preferred way to clean oil from the environment,” He said.

132．What prevented cork from being used for oil leaks?

A．Its unsteady state. B．Its low effectiveness.

C．Its limited accessibility. D．Its environmental impact.

133．What does the underlined word “attenuate” in paragraph 3 probably mean?

A．Thin down. B．Gather up. C．Bring out. D．Mix with.

134．What can be learned about the laser-treated cork?

A．It saves labor costs. B．It poses radiation threats.

C．It offers a greener choice. D．It has high economic value.

135．What does He imply about cork through his words?

A．It is highly productive. B．It is theoretically reusable

C．It holds promise in oil cleaning. D．It needs improvement for future use.
