  • 2、Blind boxes, or mystery boxes, are sealed packages containing surprise items. Buyers don't know exactly what they're purchasing until they open the box. It transforms the way collectibles are marketed and purchased. Today, brands like Pop Mart have perfected the formula, offering themed blind boxes that cater to different tastes.

    The blind box phenomenon isn't limited to collectibles. Businesses across sectors can incorporate this trend to increase customer engagement, attract a wider audience, and enhance the shopping experience. Here are a few ideas for how different types of businesses can incorporate blind box concepts.

    Create mystery product boxes.

    Introduce a line of mystery boxes for your products. For example, a beauty brand could create blind boxes with a mix of skincare or makeup products. Each box could include items of varying values, creating an element of surprise for customers.

    Create exclusive (独有的) blind box series that feature one-of-a-kind items or unique packaging, which can increase demand and bring in regular customers. Offering these boxes on a seasonal or limited-time basis also adds an element of urgency, motivating customers to act quickly.

    Incorporate blind boxes in loyalty programs.

    For businesses with loyalty programs, offering blind boxes as part of a rewards program can drive engagement. This would give them a unique stimulation to continue buying and interacting with your brand.

    Adopting the blind box model can help businesses tap into the excitement and mystery that drives this trend, while also providing a fun and memorable experience for customers. By adding elements of exclusivity and variety, brands can boost sales and customer loyalty, turning each purchase into an engaging experience.

    A. Consider rarity an artistic focus.

    B. Launch limited-edition blind boxes.

    C. This trend started in Japan and quickly spread worldwide.

    D. And a fashion shop might offer mystery gift packs.

    E. Regular customers could exchange points for mystery boxes.

    F. There are countless social media groups discussing the blind boxes.

    G. It has also become a business model for industries ranging from fashion to beauty.

  • 3、Doctor Dolittle, the well-known, fictional naturalist who famously possesses the ability to converse with animals and understand their languages has now inspired a high-paying science prize aimed at cracking the challenge of interspecies communication. A grand prize of $500,000, awaits whichever research team can make real progress: not just decoding the language of another species but using it to draw a reply from an animal. Last week, an initial $100,000 went to a US team studying dolphin whistles — after decades of recording bottlenose dolphins in Florida, they identified around 20 distinct messaging whistles.

    The Coller Dolittle Challenge financed by Jeremy Coller, a vegan and animal lover, is unashamedly modelled on the Turing test (图灵测试). That 20th-century test promotes efforts to design a machine capable of imitating human conversation, and became a touchstone in the evolution of AI. It also became a focus for concerns about machines tricking, even taking over, humans. The ability to commune with other species is likely to raise similar, unsettling questions as research progresses. If we were able to decode animal chatter, should this knowledge change how we treat them, whether as pets, labour or food? The prize presents a moral challenge and it forces us to reconsider our relationships with other species.

    Philosopher Jonathan Birch, also a judge of the Jeremy Coller Centre, stressed that the Challenge is looking beyond the interspecies communication we have with pets, or that a farmer has with a sheepdog. Those relationships involve signalling and behavioural responses, Birch explains, "but that's not telling us how animals communicate with each other... this prize is about understanding it so well that we can start to join the conversation."

    While Coller hopes his charity will reshape our attitude to animals, the truth is that even groundbreaking research has largely failed to move the dialon their welfare. Recent work on cephalopod's (头足类动物) intelligence has not stopped plans to farm the creatures. We might one day be able to understand what animals are saying — but there is no guarantee we will listen.

    (1)、Why is Turing test mentioned in the passage?
    A、To stress its role and value in AI progress. B、To show its difference from the Challenge. C、To warn of concerns the Challenge may face. D、To show its use in interspecies communication.
    (2)、Which research would Birch approve of to win the prize?
    A、People communicating with their pets. B、People directing sheepdogs during work. C、Researchers recording how cattle communicate. D、Researchers interacting with birds using whistles.
    (3)、What does the "move the dial" mean in the last paragraph?
    A、Make a change. B、Win the prize. C、Slow the process. D、Continue the research.
    (4)、What's the author's attitude toward the practical effect of the research?
    A、Optimistic. B、Doubtful. C、Objective. D、Dismissive.
  • 4、Is text-messaging driving us apart? These days, we talk to each other a lot with our thumbs — sending six billion text messages a day, and likely a few billion more on services like Whats App.

    But some worry that so much messaging leads to less communication. For instance, when hanging out with friends, we'd be texting secretively at the same time, pretending to maintain eye contact but mentally somewhere else.

    New technologies often upset the way we relate to one another, of course. But such division caused by texting has a strong echo in the arguments we had over telephone a hundred years ago. The small device gave us a new way to contact one another and quickly promote new forms of socializing. Callers arranged regular "visiting" calls, dialing remote family to catch up on news.

    Soon, though, social critics thought it would be so easy to talk that we'd never leave each other alone. Others worried that the telephone sped up life, demanding instant reactions. The use of the telephone gave little room for reflection. It produced a craziness in the ordinary concerns of life which didn't make for domestic happiness. "We shall soon be nothing but transparent piles of jelly (果冻) to each other," a London writer moaned in 1897.

    However, nowadays the telephone call seems like a throwback to a gentler era. When Jenna Birch, a communication professor at the University of Iowa, started dating a man who insisted on calling her on the phone, she found it warm and delightful. So she doesn't think the shift to texting has degraded our interactions. According to her study, teenagers who text the most are also those who spend the most time face to face with friends. Communication, it seems, brings more communication, and — as she argues — just because talk happens in text doesn't mean it's not meaningful.

    Michéle Martin of Carleton University, thinks we're living through a replay of the telephone, where the things that made it valuable — instant communications — are the same that made it annoying. "People believe they are liberated because they can bring the mobile phone everywhere," Martin says. "But at the same time, they are slaves to it."

    (1)、What's the function of the first paragraph?
    A、To introduce the topic. B、To describe a scene. C、To offer an argument. D、To issue a warning.
    (2)、According to paragraph 4, what does telephone use cause?
    A、People experience very tight schedule. B、People tend to lack individuality. C、People become narrow and uninformed. D、People lose the ability to reflect.
    (3)、What can we learn from paragraph 5?
    A、Telephone calls are particularly welcomed in dating. B、Teenagers are addicted to communicating by texting. C、The shift to texting is destructive to face-to-face time. D、The meaning of communication goes beyond medium.
    (4)、What's the best title for the text?
    A、Oh My God! We've Been Here Before! B、Gone with the Wind, Dear Texting! C、Life is Too Short for So Many Texting. D、Oh, Telephone, a Tale of Two Sides.
  • 5、From an early age, Edward Norton was taught what protecting the environment really requires. His father, an environmental lawyer, founded the Grand Canyon Trust and his grandfather was a pioneer in low-income housing policy.

    Norton built his own career in a different field, becoming one of his generation's most respected actors. When Norton first became famous, he concluded that he wasn't interested in ordinary celebrity ambassador work. "I am not interested in being some weak sauce kind of spokesperson," he says. "It's not that I don't believe those things are important, but that held no nourishment for me."

    What does nourish Norton is his work with a Kenya-based organization called the Maasai Wilderness Conservation Trust which helps the Maasai people to make a living from their land through innovative means. One project that Norton is particularly proud of channels profits from the sale of carbon offsets (碳补偿) to local Maasai communities who use that money to support health, education, and conservation initiatives.

    One challenge that concerns Norton would be familiar to his father and grandfather: raising funds. This led Norton to a realization. "We can't have the conservation movement depend only on donor-funded charity," he says, "It not only can't scale; it's fundamentally unstable."

    A new model is needed. Norton and his partners argue that tourist dollars being spent in fragile places ought to remain in-country — or better yet, in-community. Norton and his team have started a company called Conservation Equity that will invest in tourism in critical places and will reinvest its profits locally, instead of paying distant shareholders.

    Norton is optimistic about the model's prospects, "I think what we are doing has no previous example to follow. The needs of people are not going to take a lower priority to the spiritual value of nature. If protecting and restoring nature can't produce a stronger and more reliable economy, the effort will fail."

    (1)、How did Norton feel about being a typical celebrity spokesperson?
    A、Enthusiastic. B、Tolerant. C、Dissatisfied. D、Confused.
    (2)、What is special about Norton's new model of conservation?
    A、Downplaying the value of nature. B、Raising funds from distant donors. C、Focusing on local children's education. D、Benefiting local economic development.
    (3)、Which of the following words best describe Norton?
    A、Confident and honest. B、Generous and talented. C、Practical and pioneering. D、Ambitious and conventional.

  • 12、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。

    I've worked at a small local grocery store three separate times in the town I live in — each bringing warm little moments that stick in my memory. The first time was from October 2023 to June 2024, the second from February 2025 to April 2025, and I'm lucky enough to be back behind the checkout counter now.

    During my first term, I grew familiar with an older lady in her 70s named Judith. What made her stand out on colder days was her jacket — soft, cream-colored, and covered in tiny printed cats that looked like they were napping. As someone who enjoys cats, I couldn't hold back my praise the first time I saw it: "That jacket is wonderful! Those cats make it feel like a hug." She laughed. saying no one had noticed it in weeks. Judith was already a regular before I started, so I quickly recognized her gentle smile and the way she always picked up a carton of milk and a loaf of whole-grain bread. Soon, we'd chat every time she came in — she' d tell me about her three cats and how they' d knock over her flower pots, while I' d share little updates about school. Just over a week ago, she even joked, "Tell your boss that the crazy cat lady down the street says you deserve a raise!"

    When I came back for the second time, Judith's face lit up. "I was so glad to see your name on the schedule again!" she said. In early March, during one of our chats, I mentioned I planned to take a day off later that month for my 20th birthday. "Well, then I' ll have to bake you some cookies," she said firmly. I'd told her a couple of weeks prior though, and so the moment had slipped my mind by the time my birthday came around.

  • 15、When Tanya Eby was in sixth grade, her close friends made a decision that they would be distant from her. First, her closest friends told her she was no longer cool enough to hang out with them — they'd1 her, cutting her out of the group. But this2 was just the tip of the iceberg.

    Eby's world3— but the loss of her friends was only part of the story. A few months earlier, her mom and stepdad had decided to4 her brother — her "anchor (锚) in life" — to live with her dad.

  • 16、Of all the study tips out there, the one I use the most to remember things is association. That connection can help you later when you think of the associated item, which will inspire the second one to pop in your brain. Here are some of the easiest ways to use it when you're trying to improve your memory.

    Make up a mnemonic (助记的) phrase. In primary school, we all learned mnemonic phrases, like "My Very Educated Mother Just Sat Upon Nine Pizzas". That one was designed to help us remember the names and orders of the planets by starting each word in the sentence with the first letter of its corresponding (相应的) planet: Mercury, Venus, Earth, etc. Loads of research shows mnemonic devices truly help remember. But if the absurdity (荒诞) of mothers sitting upon pizzas works better for you, run with it.

    Start by organizing what you need to study and look for anything that might rhyme — but make sure it all stays in order if it needs to. Use a tune you know or make up a rhyme on the spot, but repeat it to yourself over and over until it sticks. As an example, let's look at the first four basic steps to take before conducting research: Identifying and developing your topic, searching for existing research, locating materials, and evaluating your sources. It's something like, "Identify what you want to know/ but check who's done it before you go/ now you find the tools to help/ and judge the work of someone else."

    Paint a mental picture. This is what I do most often. I create little scenes for groups of words and paint a mental picture that helps me remember them. For instance, the other night I was helping my boyfriend study accounting and discovered that "book value", "carrying value", and "net realizable value" all refer to the same thing. To help him remember that, I suggested imagining a little guy carrying a book and a net. The book could be in the net or the little guy could be carrying them both separately.

    A. A rhyme here for the four steps could be available,

    B. Making up little rhymes or songs is also beneficial.

    C. It's any connection you can form between two items.

    D. But once you imagine the scene, it's hard to forget it.

    E. I prefer to make up a sentence that somehow applies to my real life.

    F. So it makes no sense or has nothing to do with the real topic at hand.

    G. Association is essential to learning theory and behaviorism.

  • 17、Most of us rarely question the accuracy (准确性) of the GPS dot that shows our location on a map. Yet when visiting a new city and using our phone to navigate (导航), it can seem as if we are jumping from one spot to another, even though we are walking steadily along the same sidewalk.

    "Cities are hard for satellite navigation," explained Ardeshir Mohamadi. Mohamadi, a doctoral fellow at the Norwegian University of Science and Technology(NTNU), is researching how to make affordable GPS receivers (like those found in smartphones and fitness watches) much more accurate without depending on expensive external correction services.

    High accuracy is especially important for vehicles that drive themselves — autonomous or self-driving cars. Mohamadi and his team at NTNU have developed a new system that allows autonomous vehicles to navigate safely through busy city environments.

    "In cities, glass and concrete (混凝土) make satellite signals reflect back and forth. Tall buildings block the view, and what works perfectly on an open motorway is not so good when you enter a built-up area," said Mohamadi. When GPS signals reflect off buildings, they take longer to reach the receiver. This delay (延迟) throws off the calculation of distance to the satellites, which makes the reported position inaccurate. Such urban environments are known as "urban canyons". It is similar to being at the bottom of a deep valley, where signals reach you only after multiple reflections from the walls.

    "For autonomous vehicles, this makes the difference between confident, safe behavior and hesitant, unreliable driving. That is why we developed SmartNav, a type of positioning technology designed for ‘urban canyons'," explained Mohamadi.

    Not only are the satellite signals disrupted (受干扰) down between the tall buildings, but the signals that are correct do not have enough accuracy. In order to solve this problem, the researchers have combined several different technologies to correct the signal. The result is a computer program that can be integrated(合并) into the navigation system of autonomous vehicles.

    (1)、What is Mohamadi's research goal?
    A、To cut GPS cost. B、To make new smartphones. C、To improve GPS receivers' accuracy. D、To create new correction services.
    (2)、Why do GPS signals fail in cities?
    A、Signals reflect and are blocked. B、Satellites work poorly in cities. C、Phones lack navigation apps. D、Users walk too slowly.
    (3)、What can we infer about SmartNav?
    A、It's a cheap phone app. B、It needs new satellites. C、It's for open motorways. D、It helps self-driving safety.
    (4)、What will be the result of the research probably?
    A、A signal-correcting program. B、A user-friendly type of self-driving car. C、A new GPS receiver. D、Special building material.
  • 18、Scientists at Washington University School of Medicine in St. Louis have uncovered a new way that brown fat can improve the body's metabolism (新陈代谢). This process allows cells to use more fuel and produce heat, improving overall metabolic health. Conducted in mice, the research points to new possibilities for using brown fat to address metabolic conditions.

    Brown fat is known for its ability to turn energy from food into heat. Unlike white fat, which stores energy, or muscle, which uses energy immediately, brown fat helps keep the body warm in cold environments. Being exposed to cold can increase the amount of brown fat, and scientists have long suggested that turning it on could support weight loss by increasing calorie burning.

    "We've identified the body can burn more energy by helping brown fat produce more heat," said senior author Irfan Lodhi, PhD. Promoting this kind of metabolic process could support weight loss or weight control in a way that is perhaps easier to maintain over time than traditional dieting and exercise. It's a process that basically wastes energy — increasing resting energy use — but that's a good thing if you're trying to lose weight."

    While human bodies can produce fatty acids (酸) (the ones brown fat uses for heat generation), they are also found in dairy products and human breast milk. Lodhi said this raises the possibility that a dietary intervention (干预) based on these fatty acids — such as a special food or "nutritional supplement" — could strengthen this heat-production pathway and enlarge its potential benefits.

    "While our studies are in mice, there is evidence to suggest this pathway is useful in people," Lodhi said. "Previous studies have found that individuals with higher levels of these fatty acids tend to have lower potentials to be overweight. But since one does not cause the other, our long-term goal is to test whether dietary or other treatments could be helpful in dialing up this heat production pathway in peroxisomes (过氧化物酶体) and helping people lose weight and improve their metabolic health."

  • 19、Located at an altitude (海拔) of over 4,500 meters above sea level in Burang county of Ngari prefecture, Southwest China's Xizang autonomous region, Mapam Yumco Lake — also called Lake Manasarovar — holds two important titles: one of the world's highest freshwater lakes and "Mother of Rivers", as its waters feed the headwaters (上游源头) of the Ganges, Indus, Sutlej, and Yarlung Zangbo, supporting life beyond the Himalayas. For over a decade, 42-year-old Dradul has devoted himself to guarding this precious ecosystem.

    A typical workday for Dradul begins with a 10-kilometer motorcycle patrol (巡逻) by mid-morning, following a fixed route around the lake. His bag is always stocked with essentials: binoculars (双筒望远镜) to scan for waterbirds, a notebook to record wildlife species, wildlife numbers, weather, and water levels, and garbage bags to collect rubbish. He also carries a "life-saving kit" — zanba, drinking water, a thick coat, a sun mask, and simple tools for helping injured animals. One notable rescue saw him and his colleagues, along with local officials, free a trapped wild Yak (牦牛); they tied ropes around its horns and pulled inch by inch; then they waited 30 minutes to ensure the animal could walk and eat grass again.

    Dradul is part of a 90- guardian team responsible for nearly 99,000 hectares of the wetland, about 69,000 hectares of it being the lake. Their work — patrolling, recording, rescuing animals, and reminding tourists not to throw rubbish everywhere or damage grasslands — has, increased biodiversity: the wetland now hosts 411 plant species and 157vertebrates (脊椎动物). For Dradul, this role is life- changing. Before 2014, he moved between unstable short- term jobs; now, he earns a regular 2,000 yuan monthly and feels proud to protect the lake. "It's not just work," he says. "It's keeping the lake clean for my children and grandchildren."

    Yet challenges continue: climate change melts (融化) glaciers and changes shorelines. Some tourists break rules, and remote areas can't be patrolled daily. Dradul hopes for drones (无人机) to aid patrols and more young people to join. "With sincere hearts and hard work," he says, "Mapam Yumco Lake will never grow old."

    (1)、Why is Mapam Yumco Lake called "Mother of Rivers"?
    A、It is the world's highest freshwater lake. B、It supports biodiversity beyond the Himalayas. C、Its water supplies the headwaters of major rivers. D、It is guarded by a professional team of 90 people.
    (2)、What does the underlined word "stocked" in paragraph 2 mean?
    A、Fixed. B、Equipped. C、Connected. D、Decorated.
    (3)、How does Dradul view his role?
    A、As only a source of regular income. B、As a significant lifelong duty. C、As a challenging pressure. D、As a short-time job.
    (4)、What's the best title for the text?
    A、A Lake in Xizang B、Dradul's Daily Hobbies C、Challenges of Protecting Lakes D、High-altitude Tasks to Be Proud of
