Tell me why.” Have you found yourself listening to “ancient people” online recently? Creative vloggers (视频博主) are using AI technology to bring famous people from history like Tang Dynasty poets Li Bai and Du Fu “back to life”. These videos have become popular, showing these ancient icons speaking in modern language. In one video, Du Fu talks about his experience during the An-Shi Rebellion (755—763). In another, Ming Dynasty medical expert (专家) Li Shizhen makes fun of modern lifestyles like trying to be healthy by drinking goji berry (枸杞) water but still staying up late. “These videos make me want to learn more about important ancient people. I didn’t know much about their stories before,” said Wang Jiayi, 15, from Shandong. The new trend isn’t for everyone, however. The way these ancient people speak, in high tones (声调) and always asking questions, annoys (使心烦) some people. “They’re too pushy (压迫感的), which is different from how they really were,” said 14-year-old Wang Shutong from Jiangsu. Xia Boen, 14, from Hubei, felt the same. But he was surprised to find that he “remembered almost everything they said about their experiences and achievements” because of the speaking style in the videos. These videos use a more modern way to let ancient people “speak for themselves”. However, “we should be careful with these videos and make sure they are not sharing wrong information,” noted Nanfang Daily. 回答下面5个问题，每题答案不超过6个词。 1．How do creative vloggers bring ancient people “back to life”? 2．What does Li Shizhen do in one video? 3．What does Wang Shutong think of these ancient people in the videos? 4．Why did Xia Boen remember almost everything they said in the videos? 5．What should we teenagers do about these videos? 【答案】1．Using AI technology. 2．He makes fun of modern lifestyles. 3．They are too pushy. 4．Because of the speaking style. 5．Be careful with wrong information. 【导语】本文是一篇说明文，主要介绍了创意视频博主利用AI技术让杜甫等古代名人“复活”，视频受欢迎，有人因古人说话方式不满，有人因视频记住古人经历成就，且要注意视频可能存在分享错误信息的情况。 1．根据“Creative vloggers (视频博主) are using AI technology to bring famous people from history like Tang Dynasty poets Li Bai and Du Fu ‘back to life’.”可知，视频博主们正在利用人工智能技术让历史上的名人“起死回生”，故填Using AI technology. 2．根据“In another, Ming Dynasty medical expert (专家) Li Shizhen makes fun of modern lifestyles like trying to be healthy by drinking goji berry (枸杞) water but still staying up late.”可知，他取笑现在的生活方式，故填He makes fun of modern lifestyles. 3．根据“‘They’re too pushy (压迫感的), which is different from how they really were,’ said 14-year-old Wang Shutong from Jiangsu.”可知，认为他们太有压迫感，故填They are too pushy. 4．根据“But he was surprised to find that he ‘remembered almost everything they said about their experiences and achievements’ because of the speaking style in the videos.”可知，由于视频中的说话风格，他“几乎记住了他们所说的一切经历和成就”。故填Because of the speaking style. 5．根据“we should be careful with these videos and make sure they are not sharing wrong information”可知，我们应该小心这些视频，确保它们没有分享错误的信息，故填Be careful with wrong information. 02 阅读理解 （2025·江苏南京·模拟预测）A device used to treat brain injuries worked so well. Following a trial (试验), some patients refused to have theirs turned off. The trial, which began in 2018, involved five people between the ages of 22 and 60. They all had problems which were related to mental activities like thinking or reasoning after having serious brain injuries for 3 years or more. The injuries meant they had difficulty performing some tasks. For the trial, doctors implanted (植入) a tiny device into each patient’s brain during an operation. The device used “deep brain stimulation” (DBS), which rebuilds connections between neurons. Neurons are tiny cells, and there are billions of them in the brain. Whenever you do something, chemical and electrical signals move between your neurons. The tiny device applied electricity to parts of the brain. The trial was the first to focus DBS on a part of the brain that deals with consciousness (意识). It helped people be aware of what is around them and be able to respond (作出反应) to it. After the devices were put into the brains, the patients in the study had them turned on for 90 days, for 12 hours a day. This had a great influence on their lives. They could suddenly do things, like reading a book or playing video games, that used to be impossible because of their brain injuries. They also reported feeling less tired and could get through the day without napping. After 90 days, researchers wanted to turn off some of the patients’ devices. Two people were so happy with the difference the device made in their lives that they refused. Finally, one person agreed to have theirs turned off—and their brain performance got worse. Gina Arata, a patient who took part in the trial, said, “I can remember how much money is in my bank account. I wasn’t able to read, but after the implant I bought a book... and loved it and remembered it.” Nicholas Schiff, one of the authors of the study, called it a “pioneering moment.” Scientists hope the implant will change the lives of more people with serious long-term brain injuries. 1．Which of the following is TRUE about the patients in the trial? A．They have problems with mental activities. B．The patients include both children and adults. C．Only four patients are invited to be in the trial D．All of them get injured almost at the same time. 2．What does the word “It” refer to in Paragraph 2? A．The research team. B．The serious brain injury. C．The use of DBS device. D．The chemical signal between neurons. 3．Which is NOT mentioned as a result of using the device? A．Patients will feel less tired than before. B．Patients will have more need for napping. C．Patients may have the ability to read books. D．Patients’ memory for daily tasks will be better. 4．What is the right order of the following steps of the trial? a. Researchers tried to turn off some patients’ devices. b. Doctors implanted tiny devices into patients’ brains. c. Patients had their devices turned on for 12 hours daily. d. Two patients refused to let researchers turn off the device. e. Patients showed improved cognitive abilities like reading. A．a-b-c-e-d B．a-b-d-e-c C．b-c-e-a-d D．b-e-c-a-d 5．Which is the best title for this article? A．Brain Surgery Risks: A Patient’s Story B．The Way Neurons Send Signals in the Brain C．A New Device for Patients with Brain Injuries D．A New Discovery of A Cure For All Brain Injuries 【答案】1．A 2．C 3．B 4．C 5．C 【导语】本文主要介绍了一种用于治疗严重长期脑损伤的深部脑刺激DBS设备的临床试验：包括试验对象、设备原理、试验过程与结果，以及该设备的意义——科学家希望它能改变更多严重脑损伤患者的生活。 1．细节理解题。根据“They all had problems which were related to mental activities like thinking or reasoning after having serious brain injuries for 3 years or more.”可知，他们都在遭受严重脑损伤三年或更久后，出现了与思考、推理等心智活动相关的问题。故选A。 2．词句猜测题。根据“The trial was the first to focus DBS on a part of the brain that deals with consciousness. It helped people be aware of what is around them and be able to respond to it.”可知，该试验首次将深部脑刺激DBS聚焦于大脑中负责处理意识的区域。这一做法帮助人们感知周围的事物，并能够对其作出反应，因此此处it指代DBS设备的使用。故选C。 3．细节理解题。根据“They also reported feeling less tired and could get through the day without napping.”可知，他们还反馈说自己没那么容易累了，并且能够一整天不午睡也撑得下来，B项表达错误。故选B。 4．细节理解题。根据“doctors implanted a tiny device into each patient’s brain during an operation...the patients in the study had them turned on for 90 days, for 12 hours a day...They could suddenly do things, like reading a book or playing video games...After 90 days, researchers wanted to turn off some of the patients’ devices...Two people were so happy with the difference the device made in their lives that they refused.”可知，医生在手术中为每位患者的大脑植入了一个微型装置；参与研究的患者将这些装置开启了90天，每天开启12小时；他们突然能够做到一些原本因脑损伤而无法完成的事，比如看书或玩电子游戏；90天后，研究人员想要关闭部分患者的装置；有两名患者对装置给他们生活带来的改变感到非常满意，因此拒绝了关闭装置的要求，对应b-c-e-a-d。故选C。 5．最佳标题题。根据文章可知，本章围绕治疗严重脑损伤的DBS设备临床试验展开，包括试验对象、原理、过程、结果及意义，因此文章标题应为A New Device for Patients with Brain Injuries。故选C。 03 七选五 （2025·江西赣州·模拟预测）请先阅读下面短文，掌握其大意，然后根据短文内容从下面方框内的七个选项中选择五个还原到文中，使短文意思通顺、结构完整，并在答题卡上将其序号涂黑。一空一句。 Some of the jobs which were common fifty years ago are hardly seen now, and some popular jobs today may disappear in twenty years. 1 Space tour guide People have always wanted to take an exciting trip to space. 2 Anyone who wants to watch the sun rise and set over the Earth will be able to go on space trips. And for this kind of trip, travelers will need a tour guide. The tour guide can tell them what they are seeing and keep them safe. 3 AI psychologist (心理学家) AI is used in more and more real-life jobs. And machines will be more like people. 4 An AI psychologist needs to know about both psychology and technology. Their job is to make sure future supercomputers work well. Human-technology integration (融合) specialist (专家) There are so many new technologies. People may need help to understand and use them.
