This smart technology is not a fantasy㊶.Many of these new innovations㊷ are already available㊸ and being used in some homes.In this sense㊹，the home of tomorrow is already the home of today.Nevertheless㊺，it will take some years before most new homes begin to use this new technology. ◎ 智能的家让生活更加便利 你忘记过锁家门吗？或是你忘记过关掉电视或电脑吗？诸如此类的事情经常发生在我们身上，浪费资源，有时还会引发问题。然而在不久的将来，我们将生活在智能的家里。智能的家会在我们外出时锁好家门，会在我们忘记关掉电视的时候替我们关上。这样的智能家居将保障我们的安全，节省我们的能源，为我们提供一个更为舒适的居住环境。 智能控制 今天，我们必须使用开关来控制我们的电灯，使用旋钮来控制我们的家用电器，使用遥控器来控制我们的电视 学生用书第36页 机和空调。未来，我们每天都能使用先进的技术来自动控制家里几乎所有的东西。未来的住宅将使用集成传感器来感应你每天早晨何时出门，然后自动进入节能模式。你再也不用想着自己打开或关闭各种开关。你的住宅还能了解你的日程安排和喜好，所以每天晚上你回到家时，一切都已经准备就绪。在你步入家门的一刹那，灯光亮起，你最喜爱的音乐或电视节目随即开启，而且你会发现晚餐也已备好。所有的控制器都将响应语音指令，因此如果你想要改变日程安排，你只需大声说出你的想法，家居系统就会照办。 定期健康检查 此外，你的智能家居每天都会监测你的健康状况。例如，你的床铺会记录你每晚的睡眠状况，还能检测你的体重。如果你开始有睡眠或体重问题，它会将警告发到你的手机上。此外，就如何实现更加健康的饮食和更好的睡眠，它还会给予你建议。智能马桶也会持续跟踪你的健康状况。如果发现异常情况，或是你得了癌症等重大疾病，智能马桶会提前警告你，并有可能挽救你的生命。 不再有事故 智能家居将能够防止事故造成严重损害。例如，如果水管漏水或者发生电线短路，你的智能家居会检测出来，并给你提供相关的信息。这样一来，你就能够在家里水流满地或着火前及时解决问题。 这种智能技术不是幻想。这些新近的革新中有许多已经唾手可得，并且正在一些住宅中使用。从这个意义上说，明日之家已经是今日之家。然而，还需要过些年大多数新住宅才会开始使用这种新技术。 课时测评5　Section Ⅰ　Reading and Thinking—Reading comprehension (时间：45分钟　满分：50分) (本栏目内容，在学生用书中以独立形式分册装订！) Ⅰ.阅读理解(每小题2.5分，共37.5分) A (2024·福建华安一中高二10月考) Booking flights can be really exciting，but the prices might shock you into not booking your dream vacation.Never fear! We've offered some best tips for finding the cheapest airfares. 　　◆Be Flexible with Your Travel Dates and Times 　　Airline ticket prices vary greatly depending on the day of the week and time of the year.In general，Fridays and Sundays are the most desirable days，so tickets will be pricier.Prices are cheaper if you fly after a major holiday.Airlines know when a festival，holiday，or school break is coming up—and they raise prices accordingly.Be flexible with your dates and times，and you'll save yourself some major money. 　　◆Use Multiple Flight Platforms 　　Checking between the different platforms can often provide you with better insights into flight combinations and prices—for the same exact flights.Different platforms have different advantages and features，so play around with them all.You'll quickly determine the one(s) you like best! 　　◆Check for a Student Discount 　　As a student，you might be in luck.Some airlines，say，SAS (Scandinavian Airlines)，have a student ticket which means that for up to one week before departure，students pay the cheapest fare.Normal travelers at that time have to pay a much higher price，but a SAS Youth Ticket may be only one quarter the price of a normal ticket. 　　◆ Keep an Eye for Special Deals 　　Before looking for specific flights，make sure you've signed up for some newsletters.Joining the mailing list for airlines will give you access to the absolute best deals.More often than not，cheap flights are only available for a limited window (usually 24 hours)．Keeping your eye on the deals will ensure you don't miss an amazing opportunity. 语篇解读　本文是一篇应用文。文章主要介绍了一些寻找最便宜机票的最佳建议。 1.

A．Turn the stove off directly. B．Give out a warning sound. C．Activate a sensor in the house. D．Send a message to a connected phone. 答案：A 解析：细节理解题。根据第四段中的“The sensor will automatically turn the stove off if it no longer detects movement around the appliance after a certain period of time”可知，该设备长时间感知不到炉具附近的动静时，会自动关掉它。 10．What will future smart home devices be like according to Mynatt? A．They will provide medical advice. B．They will be more like caregivers. C．They will become more personalized. D．They will replace caregivers in most cases. 答案：C 解析：推理判断题。根据第五段中Mynatt所说的“They will learn more about your habits...of your health that need the most attention”可知，未来智能家居设备会收集数据，更加了解用户的习惯、喜好、日常作息、常忘吃药的时间和需要特别关注的健康问题。因此可推断，她认为未来智能家居设备会变得更加个性化。 11．What did Albert Bolet say about most seniors? A．They are willing to use smart home devices. B．They find it hard to keep up with new technology. C．They prefer a simple life without technology. D．They are becoming more dependent on the Internet. 答案：A 解析：推理判断题。根据最后一段中内容可推断，Bolet认为大多数老年人乐意使用智能家居设备。 D (2024·山东名校考试联盟高二上期中) Scientists at the UCL Institute for Neurology have developed new tools，based on AI language models，that can characterize subtle signatures in the speech of patients diagnosed with schizophrenia(精神分裂症)．The research，published in PNAS，aims to understand how the automated analysis of language could help doctors and scientists diagnose and assess psychiatric(精神病的)conditions. 　　Currently，psychiatric diagnosis is based almost entirely on talking with patients and those close to them，with only a minimal role for tests such as blood tests and brain scans.However，this lack of precision prevents a richer understanding of the causes of mental illness and the monitoring of treatment. 　　The researchers asked 26 participants with schizophrenia and 26 control participants to complete two verbal fluency tasks，where they were asked to name as many words as they could either belonging to the category “animals” or starting with the letter “p” in five minutes.To analyze the answers given by participants，the team used an AI language model to represent the meaning of words in a similar way to humans.They tested whether the words people naturally recalled could be predicted by the AI model，and whether this predictability was reduced in patients with schizophrenia. 　　They found that the answers given by control participants were indeed more predictable by the AI model than those generated by people with schizophrenia，and that this difference was largest in patients with more severe symptoms.The researchers think that this difference might have to do with the way the brain learns relationships between memories and ideas，and stores this information in so called “cognitive maps”． 　　The team now plan to use this technology in a larger sample of patients，across more diverse speech setting，to test whether it might prove useful in the clinic.Lead author，Dr Matthew Nour，said：“There is enormous interest in using AI language models in medicine.If these tools prove safe，I expect they will begin to be used in the clinic within the next decade.” 语篇解读　本文是一篇说明文。文章主要介绍了科学家们如何利用AI技术帮助诊断精神分裂症患者的病情。 12．What is the disadvantage of current psychiatric diagnosis? A．It is greatly related to blood tests. B．It mostly relies on talking with patients. C．It refers to the words of patients' family. D．It can't comprehend schizophrenia deeply. 答案：D 解析：细节理解题。根据第二段中“with only a minimal role...this lack of precision prevents a richer understanding of the causes of mental illness...”可知，由于过于依赖跟病人及其周围的谈话导致的缺乏精确性，使得无法深入了解病人状况，D项和原文“prevents a richer understanding of the causes of mental illness”为同义转换。 13．What is Paragraph 3 mainly about? A．The process of the research. B．The tasks of the participants. C．The performance of researchers. D．The predictability of AI language models. 答案：A 解析：段落大意题。该段首句提到挑选两组人员参加测试，然后描述测试内容和过程，以及测试的目的等，因而本段介绍了整个测试的过程。 14．What is Dr Matthew Nour's attitude toward AI language models? A．Unclear. B．Positive. C．Doubtful. D．Negative. 答案：B 解析：观点态度题。根据最后一段中“There is enormous interest in using AI language models in medicine...I expect they will begin to be used in the clinic within the next decade.”可知，其态度是积极的。 15．What can be a suitable title for the text? A．AI language new tools used in the clinic B．AI language tools developed by scientists C．AI language models treating schizophrenia D．AI language models diagnosing schizophrenia 答案：D 解析：标题归纳题。本文主要介绍了科学家创造的AI研究模型。结合首段末句“The research，published in PNAS，aims to understand how the automated analysis of language could help doctors and scientists diagnose and assess psychiatric(精神病的)conditions.”可知，研究目的是帮助医生诊断病情，而不是治疗疾病。 Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2024·山东师大附中高二期末) AI refers to the ability of machines to interpret(诠释)data and act intelligently，meaning it can make decisions and carry out tasks based on the data at hand. 1 And it will change our lives in very real ways.Here are four reasons why AI is going to change the world. 　　AI is everywhere.Have you ever asked a voice system for a morning weather report，passed through a public space that uses facial recognition technology，or bought a product recommended to you by an e-commerce website？Of course you have. 2 So obviously，people's daily routine has been already surrounded by AI. 　　 3 The impact of AI is already being felt in a wide range of industries，such as banking，farming and manufacturing(制造业)．In health care，AI is being used to identify diseases and even predict diseases in some cases in order to help doctors and their patients make better treatments and make decisions on lifestyles. 　　AI will make our working lives better.Journalism is one industry that is undergoing an AI revolution(革命)．And many AI tools help journalists identify and write stories.At some magazine companies，for example，an AI-driven content management system is used to identify real-time trending topics，suggest improvements to headlines and discover relevant images. 4 　　AI is becoming more affordable for the masses.In the past，to work with AI，we would need expensive technology and many scientists. 5 Like many technology solutions，with a rapidly growing range of ready-made service solutions aimed at businesses of all sizes，AI is now readily available on an as-a-service basis. A．That's no longer the case now. B．It is a truly world-changing technology. C．AI will offer us better medical treatments. D．AI is going to change many industries. E．Most of us have done one or all of these things. F．This enables journalists to focus their effort on telling stories. G．Facial recognition technology brought convenience to life. 语篇解读　本文是一篇说明文。文章主要介绍了人工智能将会改变世界的四个原因。 1．答案：B 解析：根据下文中的“it will change our lives in very real ways.Here are four reasons why AI is going to change the world”可知，这里提到人工智能将会改变我们的生活。B项“这是一项真正改变世界的技术”引出下文，符合语境。 2．答案：E 解析：根据上文中的“Have you ever asked...recommended to you by an e-commerce website？”可知，这里主要提到人工智能在我们生活中的使用。E项“我们大多数人都做过一件或所有这些事”承接上文，符合语境。 3．答案：D 解析：空处位于段首，应为本段的主旨句。根据下文中的“The impact of AI is already being felt in a wide range of industries”可知，这一段讲述人工智能改变了多个行业。D 项“人工智能将改变许多行业”能概括本段主旨。 4．答案：F 解析：根据上文中的“Journalism is one industry...discover relevant images”可知，这一段讲述人工智能在人们工作上的作用，重点举例说明了其在新闻业的影响。F项“这能让记者集中他们的精力讲述故事”承接上文，符合语境。 5．答案：A 解析：根据上文中的“In the past，to work with AI，we would need expensive technology and many scientists”可知，过去人工智能成本很高；再根据下文中的“AI is now readily available on an as-a-service basis”可知，现在大多数人都可以使用人工智能。故A 项承上启下，符合语境。 学科网（北京）股份有限公司 $$
