That long gap has finally come to an end. Researchers have formally recognized Leopardus tilcayo, a small spotted cat native to Bolivia’s cloud forests, as the first new wild cat species discovered in over 100 years. 1. ____________ The new species belongs to the ocelot lineage, a group of small wild cats unique to South America. After genetic analysis and long-term comparison with known cat species, the research team published their findings in Current Biology in September 2026. 2. ____________ Besides its small size, this newly identified creature has distinctive spotted patterns adapted to thick forest environments. Interestingly, the discovery was not made through large-scale field exploration. 3. ____________ Years ago, a local family in Bolivia raised one of these cats as a pet. They later sent the spotted animal to a local wildlife sanctuary, where biologists noticed its unusual physical features. These subtle differences inspired researchers to launch in-depth genetic testing. Genetic research confirmed that Leopardus tilcayo split from its closest relatives approximately 1.4 million years ago. 4. ____________ Even after such a long separation, the cat looks extremely similar to other local wild cat species, which explains why it has been misclassified for decades. At present, scientists still know very little about the new species’ living habits, population size and exact distribution. The unique cloud forest habitat it relies on is facing growing pressure from deforestation and agricultural expansion. 5. ____________ The new discovery not only fills a gap in biodiversity research but also reminds people of the importance of protecting vulnerable forest ecosystems. 选项 A. It proves that small wild cat species have great genetic diversity. B. Instead, it began with a casual observation of a rescued individual. C. It is physically smaller than ordinary domestic cats and weighs roughly three pounds. D. This long evolutionary separation makes it a genetically independent species. E. Therefore, targeted protection measures are urgently needed for the rare creature. F. South American wild cats have received adequate public protection in recent years. G. The breakthrough has excited biologists studying mammalian biodiversity. Passage 2 社交媒体“孤独博主”现象 Twenty-four-year-old Lavanda, arriving in London from New Zealand, once wanted to go out for a cocktail but found no one to go with. She recorded her embarrassment as a video diary. She watched it back and believed sharing it might help someone. 1. ____________ The video has gained more than 600,000 views. Lavanda said that talking to the camera about her loneliness helped her cope with her fears around social situations. She recalled struggling to make friends all her life. As she grew up, she felt huge panic when she found she had few friends. 2. ____________ In fact, Lavanda’s situation is not rare. A growing number of young online creators share videos of their solitary daily life. Sarah-Jane Hoadley is one of the so-called “loneliness influencers”, a new type of social media creator who embraces living alone. 3. ____________ She has found inner peace in these simple quiet moments. However, opinions about this trend are divided. Some viewers think these creators promote self-love. 4. ____________ They argue that such videos may encourage social isolation at a time when loneliness has become a global public health concern. Clinical psychologist Lauren Cook holds a balanced view. She says people can enjoy peaceful alone time, meanwhile keeping the willingness to socialize and maintain relationships. 5. ____________ The key is to find a healthy balance between staying alone and connecting with others. 选项 A. But others criticize this kind of online content. B. Her video soon became popular and won wide feedback. C. She spends her days working and evenings quietly staying with her cat. D. Many young people are suffering from the pain of being alone in modern society. E. People do not have to feel ashamed of enjoying time by themselves. F. It is necessary to keep a healthy harmony between being alone and socializing. G. She used to lie about her weekends when others asked about her social life. Passage 3 未成年上网硬约束 The Internet brings teenagers rich learning resources, yet it also carries risks such as online addiction and harmful information. Many countries have introduced rules to limit young people’s online behaviour. 1. ____________ China has put forward strict requirements for online platforms to strengthen protection for minors. Platforms are required to set up special youth mode. 2. ____________ When teenagers use the service, the system will automatically limit daily usage time and block inappropriate content. Some parents welcome the tough rules. They believe such measures can reduce teenagers’ chances of being exposed to violence or misleading information online. 3. ____________ They argue that too much restriction may prevent teenagers from making full use of online educational resources. Experts point out that online protection for minors should not only rely on platform rules. 4. ____________ Parents are supposed to communicate more with their children and guide them to form healthy digital habits. The hard rules are not meant to keep teenagers away from the Internet completely. 5. ____________ Only with joint efforts from platforms, families and schools can teenagers safely benefit from the online world. 选项 A. However, some people hold different opinions. B. It will be activated once users finish real-name identification. C. It aims to create a safer online environment for young users. D. Teenagers should stay away from all kinds of online information. E. Family education also plays an important role in this process. F. Online games are the only source that harms teenagers’ mental health. G. It guides teenagers to make good use of online resources properly. Passage 4 旅行失眠与首夜效应 Have you ever found it hard to fall asleep on your first night in a hotel or a strange room? This common phenomenon is called the first-night effect. 1. ____________ Scientists have studied this strange sleep pattern for years. They found that when people stay in an unfamiliar place, one half of the brain remains more active during sleep. 2. ____________ It will wake you up quickly once it senses possible danger nearby. This special brain state comes from ancient human survival instincts. Long ago, our ancestors had to stay alert when sleeping in unknown wild areas. 3. ____________ Even though modern people no longer face such dangers, the instinct still stays inside our brains. Luckily, the first-night effect usually disappears on the second night. 4. ____________ You can take familiar items like your pillow or blanket to the hotel. Keeping your usual bedtime routine also helps reduce sleep trouble. The first-night effect is not a sign of sleep disease. 5. ____________ It is just a protective system of our brain. 选项 A. This half acts like a guard while you rest. B. Here are simple ways to help you get better sleep on trips. C. It describes the difficulty falling asleep in a new sleeping environment. D. People who often travel will never suffer from the first-night effect. E. So they needed to keep part of their brain awake to avoid natural enemies. F. It means your brain is still working to judge whether the new place is safe. G. Many people choose to take sleeping pills to deal with this travel sleeplessness. 参考答案 + 逐题原文定位详解 Passage 1 答案：1.G 2.C 3.B 4.D 5.E 1. G 解析：前文介绍时隔百年才发现新野生猫科物种，G选项“这一突破令研究哺乳动物生物多样性的生物学家倍感振奋”承接这个重大科研发现，自然过渡到下文对该物种的详细介绍。 2. C 解析：空后出现Besides its small size（除了体型小之外），说明空格处需要介绍体型特征。C选项描述它体型比普通家猫更小，体重约三磅，和后文small size形成呼应。 3.
