Ⅲ.阅读理解(每小题2.5分，共20分) A (2024·山东菏泽高一期末) When Stanford University student Ellen Xu，now 18，was a five-year-old in San Diego，California，she clearly remembers that her parents rushed her little sister to the hospital.Three-year-old Kate had fallen seriously ill；she had a fever，reddened eyes，and some swelling(肿胀) in her hands and tongue. At first，the puzzled doctors thought she had flu，but when her condition didn’t improve，the Xus returned to the clinic room，where a doctor by chance had a similar earlier experience with such symptoms(症状) in the blood known as Kawasaki disease.Though rare(罕见的)，it’s the leading cause of the heart disease in babies and young children，and its causes remain unknown. The doctor knew how to treat it：He ordered some medicine for Kate，and finally she shook off the illness without suffering damage to her heart. Xu remembers being curious about her sister’s illness condition and was amazed that the grown-ups couldn’t answer her questions about why it was so hard to check.“In my mind，it was this puzzle I wanted to solve，” she says. Ten years later，wanting to enter a high school science fair，she had an idea.What if we had a doctor in our pocket？So she created just that: Using AI，Xu designed a program that uses visual facts to check the disease based on five physical symptoms. The technology works the same way as apps that can identify birds and plants with photos you’ve taken on your cellphone.Worried parents can upload a photo that they have taken of their child，and the technology will scan the picture for symptoms of the disease，which often have a strong visual factors，such as a swollen tongue. Xu’s invention has been applied as a web app on the website.“The technology could also be developed for recognizing some other diseases，” she says.“It means a lot to me.I want to use AI to help people live happier and healthier lives.” Xu says that her sister Kate，now in her third year of high school with dreams of becoming an environmental engineer，is strong and healthy. 语篇解读　本文是一篇记叙文。文章讲述了女孩Ellen Xu利用人工智能技术创造了一个程序，可以根据上传的照片中显示的症状检测川崎病，帮助人们快速获得诊断，改善健康状况。她的发明已被应用于网页应用程序中，她希望通过人工智能帮助更多人过上更快乐、更健康的生活。 1．Why did the author mention Kate’s illness? A．To explain who treated Kate’s illness. B．To prove how serious Kate’s illness was. C．To show how much Ellen loved her sister. D．To tell why Ellen wanted to solve the puzzle in her mind. 答案　D 解析　推理判断题。前三段叙述了Ellen在5岁时经历了妹妹Kate得川崎病的情景，以及Kate被治愈的过程，第四段介绍因为妹妹的病情，Ellen萌生了想要解决这个问题的念头。由此可知，作者提到Kate的病是为了说明Ellen想解开心中难题的动机。故选D。 2．Why did Ellen design the program? A．To save her sister. B．To earn a prize. C．To check a rare disease. D．To identify birds and plants. 答案　C 解析　细节理解题。根据第五段中“So she created just that：Using AI，Xu designed a program that uses visual facts to check the disease based on five physical symptoms.”可知，Ellen设计这款程序是为了核查这种罕见病。故选C。 3．Which of the following can best describe Ellen according to the passage? A．Determined and careful. B．Creative and helpful. C．Diligent and selfless. D．Active and easy-going. 答案　B 解析　推理判断题。根据第五段中“So she created just that：Using AI，Xu designed a program...”可知，Ellen创造了一个可以核查川崎病的程序，所以她是有创造力的；根据倒数第二段中她所说的“I want to use AI to help people live happier and healthier lives.”可知，Ellen想用人工智能帮助人们改善生活，所以她是乐于助人的。故选B。 4．What is the best title for the text? A．A Girl’s Road to Invention B．An Invention Helping Doctors C．A Girl Recovering from a Disease D．A New Method to Treat a Disease 答案　A 解析　标题归纳题。通读全文可知，文章主要围绕女孩Ellen发明了一款检测罕见病的程序的经历展开——先是讲述了她这个想法的由来，再描述了她在十年后利用人工智能技术创造了一个程序，可以根据症状检测该疾病，以及她的发明已被应用于网页应用程序中。由此可知，A项“一个女孩的发明之路”概括了Ellen的经历，是本文的最佳标题。故选A。 B Pet and animal-related apps are creating cybersecurity risks to their owners，new research has shown.While being able to keep track of your cat and dog may be an attractive benefit to many pet owners as it can provide peace of mind，allowing a third party to track your movements may be much less attractive. Computer scientists at Newcastle University and Royal Holloway，University of London have exposed multiple security and privacy issues by evaluating 40 popular Android apps for pets.The results show that several of these apps are putting their users at risk by exposing their login or location details. Password vulnerability(漏洞) was one of the areas exposed by the team.They identified three applications that had the user’s login details visible in plain text within non-secure HTTP traffic.This means that anyone is able to observe the Internet traffic of someone using one of these apps and will be able to find out their login information.In addition to login information，two of the apps also showed user details，such as their location that may enable someone to gain access to their devices and risk a cyber-attack. Another area of concern identified in the study was the use of trackers.All but four of the applications were found to feature some form of tracking software.A tracker gathers information on the person using the application，on how they use it，or on the smartphone being used. Scott Harper is a PhD student at Newcastle University’s School of Computing and the lead author of the study.He said：“Pet tech such as smart collars and GPS trackers for your cat or dog，is a rapidly growing industry and it brings with it new security，privacy，and safety risks to the pet owners.We would urge anyone using these apps to take the time to ensure they are using a unique password，check the settings and ensure that they consider how much data they are sharing or willing to share.” 语篇解读　本文为一篇说明文。一项新的研究表明，宠物和动物相关的应用程序正在给它们的主人带来网络安全风险。 5．What’s the function of the first paragraph? A．To display the benefits of pet tracking. B．To introduce pet and animal-related apps. C．To raise the topic by giving research findings. D．To show the evidence of cybersecurity risks. 答案　C 解析　推理判断题。根据文章第一段“Pet and animal-related apps are creating cybersecurity risks to their owners，new research has shown.While being able to keep track of your cat and dog may be an attractive benefit to many pet owners as it can provide peace of mind，allowing a third party to track your movements may be much less attractive.”可知，第一段通过给出研究结果来提出本文话题。故选C项。 6．What’s the main idea of paragraph 3? A．The threat of a cyber-attack. B．The operation of HTTP traffic. C．The access to login information. D．The potential risks in password security. 答案　D 解析　段落大意题。根据文章第三段首句“Password vulnerability(漏洞) was one of the areas exposed by the team.”及整段内容可知，第三段具体讲解了密码安全方面的潜在风险。故选D项。 7．What attitude should we hold while using pet tech according to Scott Harper? A．Flexible. B．Cautious. C．Determined. D．Casual. 答案　B 解析　推理判断题。根据文章最后一段中的“Pet tech such as smart collars and GPS trackers for your cat or dog，is a rapidly growing industry and it brings with it new security，...check the settings and ensure that they consider how much data they are sharing or willing to share.”可知，Scott认为宠物软件存在隐私和安全风险，他敦促人们在使用时要谨慎。故选B项。 8．Which is the most suitable title for the text? A．Are We Safe to Use Android Apps? B．How Can We Observe the Internet Traffic? C．What Does Tracking Software Bring Us? D．Are Our Pets Leaking Information About Us? 答案　D 解析　标题归纳题。根据文章第一段首句“Pet and animal-related apps are creating cybersecurity risks to their owners，new research has shown.”及全文内容可知，本文围绕使用宠物软件会给宠物主人带来网络安全风险展开。故选D项。 Ⅳ.七选五(每小题2.5分，共12.5分) School is tough enough as it is，but distance learning presents a whole new challenge.Many students struggle to focus on their homework when they study at home，as online courses call for self-discipline(自律)． 1 Motivate(激励) yourself.Think about how traditional classroom settings motivate students to get their work done: deadlines written on a white board，friendly reminders and suggestions from teachers，and group study sessions with classmates. 2 Write down your deadlines and get in touch with your classmates to study together and quiz each other online. 3 You’re not the only one to struggle with online learning，so don’t be afraid to get in touch with your teachers and classmates with any questions you might have.Similarly，remember your teachers and classmates might reach out to you with questions as well.Respond to their messages in a timely manner to keep open lines of communication. Find a good study spot.Houses are full of distractions(分散注意力的事物)—especially if you’re in no mood to study.Set yourself up for success by reducing these distractions and creating an environment where it is easy to do schoolwork. 4 Leave your phone in another room in order to avoid temptation(诱惑) from social media or online games. Use what you have.One of the many benefits of online learning is having endless Internet resources. 5 Be familiar with study resources and open education sites，and then use them to add to your studies and quiz yourself before exams.Online classes might require more self-discipline than classroom learning，but that hard work will surely pay off. A．Manage your time. B．Be ready to ask all the questions. C．A short break is also necessary for online learning. D．You can also use these helpful methods in your own home. E．Many of them might help you understand your studies easily. F．Keep up with your online schoolwork with these tips for success. G．If possible，find a quiet place away from your housemates，family members and TV. 语篇解读　本文是一篇应用文。文章主要介绍了几种帮助青少年上好网课的方法。 1．答案　F 解析　此空设于段尾，是一个总结句，起到承上启下的作用。根据各段的首句可知，此处引出下文的四种方法。故选F。 2．答案　D 解析　此空设于段中，与上文存在指代关系。D项中的“these helpful methods”指代上文中的“deadlines written on a white board...group study sessions with classmates”。故选D。 3．答案　B 解析　此空设于段首，是一个主题句。根据下文“You’re not the only one to struggle with online learning，so don’t be afraid to get in touch with your teachers and classmates with any questions you might have.”可知，本段主题是建议积极提问。故选B。 4．答案　G 解析　此空设于段中，与上文存在解释关系。根据上文中的“creating an environment where it is easy to do schoolwork”可知G项衔接上文，符合语境。故选G。 5．答案　E 解析　此空设于段中，与上文存在指代关系。本段主要讲利用各种资源学习。E项中的them指代本段的“endless Internet resources”。故选E。 学科网（北京）股份有限公司 $$
