Two years ago, they only knew what products they had bought from factories. They did not know who their customers were, what age group they belonged to or what they really wanted to buy. Then Zhang Yue learned to use an online data tool from the selling platform. The tool helped her see which products were viewed most often, what age group liked each item best, and at what time of day people usually placed orders. With this useful information, she moved popular products to the first page and ran small discount sales in the evening, when orders were most active. Now, more customers visit the store and spend longer time choosing products. Zhang Yue says that big data helps small businesses just as much as it helps large companies. The key is to learn how to read the numbers in the data and then act on them wisely. 49. What did the store NOT know two years ago? A. What products they had. B. Where the store was. C. Who its customers were. D. How to open the door. 50. What did the data tool help Zhang Yue learn? A. Which products were popular. B. Which movies were playing. C. Which songs were new. D.

In traditional hospitals, doctors make decisions mainly based on what they see and hear during a short visit. They may miss small but important changes in a patient's body that happen slowly over time. With big data, patients can wear smart devices that collect health information all day. These devices record heart rate, sleep time, step count and blood pressure. The data is sent to a platform where it is compared with millions of other health records from around the world. When an unusual pattern appears, the system sends an early warning to both the patient and the doctor, sometimes even before the patient feels anything wrong. Big data also helps on a larger scale. Health officials can see which diseases appear more often in certain areas and at certain seasons. They can then send doctors, medicine and equipment where they are needed most, saving both time and lives. However, experts warn that health data is highly personal. Strong rules must be in place so that patients' privacy is not harmed while they enjoy the benefits of modern technology. 53. What may traditional doctors miss? A. Small changes over time. B. Large injuries at once. C. Patient's name and age. D. Hospital's phone number. 54. How do smart devices help patients? A. By replacing all doctors. B. By giving free medicine. C. By sending early warnings. D. By cancelling hospital visits. 55. What is the third paragraph mainly about? A. How smart devices record data. B. Large-scale use and privacy. C. Why traditional doctors are better. D. How to buy health devices cheaply. 56. What is the best title for the passage? A. Smart Devices Are Dangerous. B. Doctors No Longer Needed. C. Patients Must Ignore Data. D. Big Data in Healthcare. 【答案】53. A 54. C 55. B 56. D 【导语】本文介绍大数据在医疗领域的应用，包括智能设备监测、早期预警和公共卫生资源分配，同时强调隐私保护。 【详解】 53．细节理解。第一段末句说传统医生依靠短时问诊做判断，可能错过病人身体随时间发生的小变化，故选A。 54．细节理解。第二段说明当发现异常模式时，系统会向病人和医生发送早期预警，故选C。 55．段落大意。第三段先讲大数据在更大范围内的疾病分布分析，再用however转折强调隐私保护，故选B。 56．标题归纳。全文围绕大数据如何改变医疗展开，既有应用实例也有隐私讨论，最佳标题应涵盖大数据与医疗，故选D。 D Big data has brought exciting changes, but it also raises serious questions about personal privacy. Every day, people leave behind trails of personal data — from the apps they open in the morning to the stores they visit. When these pieces are put together, they can paint a clear picture of a person's life. Some argue that privacy is a price worth paying for convenience. Others believe the risks are too great. When data falls into the wrong hands, it can be used for harmful purposes. Health records, shopping history and daily routines could be shared without people's knowledge. The answer may not be to stop using big data, but to use it with rules. Governments are making laws to give people more control over their own data. Companies should be honest about what they collect and why. Schools also have a role. Teaching young people basic data literacy will prepare them for a future in which data is everywhere. The goal is not to choose between technology and privacy. It is to build a world where both can grow together — a world where data serves people, not the other way around. 57. What picture can personal data paint? A. A clear picture of life. B. A simple map of roads. C. A short list of names. D. An empty page of books. 58. What do some people believe about privacy risks? A. The price is too small. B. The data has no value. C. The risks are too great. D. The apps are all safe. 59. What should schools teach according to the passage? A. Advanced car driving. B. Traditional paper writing. C. Old phone repair skills. D. Basic data literacy. 60. What is the writer's attitude toward big data? A. Completely against it. B. Hopeful but careful. C. Not interested at all. D. Angry and worried. 【答案】57. A 58. C 59. D 60. B 【导语】本文讨论大数据带来的便利与隐私风险，强调通过法律、企业自律和学校教育实现技术与隐私的共存。 【详解】 57．细节理解。第一段末句说碎片数据拼在一起可以清晰描绘一个人的生活，故选A。 58．细节理解。第二段说明部分人认为风险太大，数据落入错误之手可能带来危害，故选C。 59．细节理解。第三段指出学校应教学生基本的数据素养，帮助他们理解信息的收集、使用和保护，故选D。 60．观点态度。文章既承认大数据的价值也强调隐私风险，结尾希望技术与隐私共同发展，态度是充满希望但保持警惕，故选B。 第二节 补全对话（共5小题；每小题2.5分，满分12.5分） A: I heard you are taking a course on big data.

B Zhang Yue's family runs a small online store that sells sports goods like shoes, bags and exercise tools. Two years ago, they only knew what products they had bought from factories. They did not know who their customers were, what age group they belonged to or what they really wanted to buy. Then Zhang Yue learned to use an online data tool from the selling platform. The tool helped her see which products were viewed most often, what age group liked each item best, and at what time of day people usually placed orders. With this useful information, she moved popular products to the first page and ran small discount sales in the evening, when orders were most active. Now, more customers visit the store and spend longer time choosing products. Zhang Yue says that big data helps small businesses just as much as it helps large companies. The key is to learn how to read the numbers in the data and then act on them wisely. 49. What did the store NOT know two years ago? A. What products they had. B. Where the store was. C. Who its customers were. D. How to open the door. 50. What did the data tool help Zhang Yue learn? A. Which products were popular. B. Which movies were playing. C. Which songs were new. D. Which games were free. 51. What does the word 'act on' mean in the last paragraph? A. Give up and forget. B. Hide from the public. C. Copy from others. D. Take action based on. 52. What is the main idea of the passage? A. Big data only helps large firms. B. Big data helps small businesses too. C. Sports goods are not popular. D. Online tools waste all time. C Big data is changing healthcare in ways that were hard to imagine just a few years ago. In traditional hospitals, doctors make decisions mainly based on what they see and hear during a short visit. They may miss small but important changes in a patient's body that happen slowly over time. With big data, patients can wear smart devices that collect health information all day. These devices record heart rate, sleep time, step count and blood pressure. The data is sent to a platform where it is compared with millions of other health records from around the world. When an unusual pattern appears, the system sends an early warning to both the patient and the doctor, sometimes even before the patient feels anything wrong. Big data also helps on a larger scale. Health officials can see which diseases appear more often in certain areas and at certain seasons. They can then send doctors, medicine and equipment where they are needed most, saving both time and lives. However, experts warn that health data is highly personal. Strong rules must be in place so that patients' privacy is not harmed while they enjoy the benefits of modern technology. 53. What may traditional doctors miss? A. Small changes over time. B. Large injuries at once. C. Patient's name and age. D. Hospital's phone number. 54. How do smart devices help patients? A. By replacing all doctors. B. By giving free medicine. C. By sending early warnings. D. By cancelling hospital visits. 55. What is the third paragraph mainly about? A. How smart devices record data. B. Large-scale use and privacy. C. Why traditional doctors are better. D. How to buy health devices cheaply. 56. What is the best title for the passage? A. Smart Devices Are Dangerous. B. Doctors No Longer Needed. C. Patients Must Ignore Data. D. Big Data in Healthcare. D Big data has brought exciting changes, but it also raises serious questions about personal privacy. Every day, people leave behind trails of personal data — from the apps they open in the morning to the stores they visit. When these pieces are put together, they can paint a clear picture of a person's life. Some argue that privacy is a price worth paying for convenience. Others believe the risks are too great. When data falls into the wrong hands, it can be used for harmful purposes. Health records, shopping history and daily routines could be shared without people's knowledge. The answer may not be to stop using big data, but to use it with rules. Governments are making laws to give people more control over their own data. Companies should be honest about what they collect and why. Schools also have a role. Teaching young people basic data literacy will prepare them for a future in which data is everywhere. The goal is not to choose between technology and privacy. It is to build a world where both can grow together — a world where data serves people, not the other way around. 57. What picture can personal data paint? A. A clear picture of life. B. A simple map of roads. C. A short list of names. D. An empty page of books. 58. What do some people believe about privacy risks? A. The price is too small. B. The data has no value. C. The risks are too great. D. The apps are all safe. 59. What should schools teach according to the passage? A. Advanced car driving. B. Traditional paper writing. C. Old phone repair skills. D. Basic data literacy. 60. What is the writer's attitude toward big data? A. Completely against it. B. Hopeful but careful. C. Not interested at all. D. Angry and worried. 第二节 补全对话（共5小题；每小题2.5分，满分12.5分） A: I heard you are taking a course on big data. (61)______ B: It's about how to use big data technology in real life.
