It’s an artificial intelligence (AI) tool. It can answer questions, tell stories and write articles. But it’s very “thirsty”, said a new study from Harvard University. ChatGPT has “homes” around the world in data centres (数据中心). When it works, the computers in the data centres get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away the pipes. When you ask ChatGPT 50 questions, it “drinks” 500 millilitres (ml) of water. Scientists used about 700,000 litres of water to build ChatGPT. The water use is very big. People can make 370 cars with the water. ChatGPT is just one of the AI tools around the world. You need data centres to do everything on the internet. There are more than 8,000 data centres around the world. The number is still growing. AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI? 21．Which of the following can ChatGPT do? ①Answer questions. ②Fly planes. ③Write articles. ④Tell stories. A．①②③ B．②③④ C．①③④ D．①②④ 22．What does the underlined word “them” refer to in Paragraph 2? A．Homes. B．Computers. C．Workers. D．Pipes. 23．If you ask ONE question, how many millilitres of water can ChatGPT “drink”? A．10. B．100. C．50. D．500. 24．What can we learn from Paragraph 4 and Paragraph 5? A．ChatGPT is the only AI tool around the world. B．The number of data centres is not growing now. C．AI tools can work in a better way without any water. D．We may have to “fight” with AI for water in the future. 25．What is the main idea of the article? A．ChatGPT is a good artificial intelligence tool. B．ChatGPT needs lots of water when it works. C．ChatGPT helps people do many different things. D．ChatGPT has “homes” around the world in data centres. （B） Have you ever wondered why so many apps are free to use? After all, they cost money to run. Well, instead of paying with money, you’re paying by sharing your personal data (数据). Then businesses buy and use the data so that they can show you targeted ads (定向广告). What happens to personal information online? Many free apps get paid by businesses that want to know about the users of the apps. What a business wants is the exact information about customers. Companies called “data brokers” collect your data—everything from your name, location and education level to the topics you search for, the websites you visit and the people you follow, and then sell it to other brokers and businesses. __________ The data is valuable. Businesses can use the information from data brokers to target their ads. It means they will show their ads to the people who are most likely to be interested in their products or services. What can we do about it? Many countries have made laws to protect personal information. For example, a law in the United States says companies must get parents’ permission to collect personal data from kids under 13. China’s law on personal information protection came into effect on November 1, 2021. At the same time, we should try to protect our data. If an app asks for something like your location, consider saying “No” first. In short, information about you is very valuable. Try to protect it. 26．According to the passage, how can people use some apps for free? A．By sharing their personal data. B．By buying and using the data. C．By showing the targeted ads. D．By talking with friends. 27．According to the passage, which picture can describe how businesses show their targeted ads? A． B． C． D． 28．According to the passage, why do “data brokers” collect personal information? A．To use the apps for free. B．To sell the information to businesses. C．To protect users’ personal data. D．To make new laws about privacy. 29．Which of the following can be put in the “________”? A．What are people interested in? B．Why do businesses show their ads? C．Why do businesses want the data? D．What are the new products? 30．Who’s the passage written for? A．Businessmen. B．App users. C．Lawyers. D．Data brokers. （C） Ever feel lost with numbers? The right graph can help! It makes data clear. Let’s look at the four most common graph types: Pie ChartIt’s good for showing a certain part of a whole and the proportion (比例) of each part. A pie chart enables you to plan your pocket money wisely:for snacks, books, and savings. Line GraphAn excellent choice if you want to describe how something changes over time. It is also good for showing big differences. Many teachers prefer using a line graph to track students’ grades. Bar GraphA bar graph can also show changes over time. However, it’s more direct to make comparisons (对比) between two or more things. That’s why we can use it to compare the popularity of different school clubs among your classmates. Venn Diagram (维恩图) A Venn Diagram features two overlapping circles. It’s perfect for sorting (分类) information. You can use a Venn Diagram to sort plants. For example, plants with green leaves go on the left; plants with flowers go on the right; plants with both go in the middle where the circles overlap. 31．Where can we probably find the passage? A．In a historical novel. B．In a tour guide. C．In a sports newspaper. D．In a maths textbook. 32．How many kinds of data display graphs are mentioned in the passage? A．3. B．4. C．5. D．6. 33．If you want to show big differences and how something changes over time, which graph would be a good choice? A．Pie Chart. B．Bar Graph. C．Line Graph. D．Venn Diagram. 34．The underlined phrase “overlapping circles” means a circle ________. A．that covers part of another circle. B．that is inside another circle. C．that is far away from another circle. D．that is drawn under another circle. 35．What is the main purpose of this passage? A．To help people create a project. B．To tell people about the use of data. C．To introduce some helpful data display methods. D．To show how Venn Diagrams are different from other ways. 第二节 阅读填空（共5小题，每小题1分，满分5分） 根据短文内容，选出适当的句子补全全文，使短文意思通顺，内容完整。阅读短文及文后A—E选项，选出可以填入各题空白处的最佳选项。 Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That’s because China has the longest mobile phone numbers in the world. Why is that? 36 Each part has a different meaning. The first three numbers tell you which mobile phone service provider you are using. For example, “135-” is for China Mobile and “155-” is for China Unicom. The fourth to the seventh digits tell you which area the number is recorded in. 37 The main reason for using 11 digits is that we have a large population. 38 But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. 11 digits can be used to make tens of billions of mobile phone numbers. That’s enough for each person to have seven or eight phone numbers to use in China. 39 Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven’t contacted (联络) for a long time, you may find that its owner has changed. Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with “0”. 40 Countries like the United States, Australia and India use phone numbers with 10 digits, while Canada’s mobile phone numbers are also 10 digits long, the same as those in the United States. A．We once had 10 digits. B．The 11 digits can be divided into three parts. C．Also, mobile phone numbers can be recycled. D．And the last four digits are random (随机的). E．So they cannot create as many numbers as we can. 三、项目情境（读写综合）（共两节，满分20分） 第一节 项目情境选择题（共5小题，每小题2分，满分10分） 【项目情景一】促销广告推荐 春节将至，各大商场和超市纷纷推出促销活动。以下是六个促销广告（A—F）。请根据下面五位同学的需求，帮助他们选择合适的广告信息，并将其字母编号填入题前的括号内。 41 The Spring Festival is coming.

These countries are found in much of Africa, South America and some parts of Asia. In the developed countries of Europe and North America, the population is growing slowly. This is because women in these countries have, on average (平均), only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world’s population lived in the developed countries. By 2050, these countries will be home to only around one tenth of the world’s people. In the developing countries, more than one billion people are still living below the poverty line (贫困线). These people do not have enough food to eat and they live in poor houses. In many developing countries, children get little time at school and people suffer from many kinds of diseases. In July, 2023, the world’s population was around eight billion. The UN has said that the world’s population will continue to grow, reaching 14 billion before it becomes stable (稳定的), or even falls. 46．Where can developing countries be found? 47．Is the population in the developed countries of Europe and North America growing fast or slowly? 48．Where do more than one billion people still live below the poverty line? 49．In many developing countries, what situation do children and people face? 50．What was the world’s population in July, 2023? 四、写作（共三节，满分30分） 第一节 语篇填词(共5小题，每小题1分，满分5分) 根据下列语篇以及所给单词的首字母写出所缺单词，在填写答题卡时，要求写出完整单词。 Numbers are e 51 in our daily lives.

Life became easier and clearer. Counting their food and money was no longer”人们能数食物和钱，生活变得更容易，更清楚，因此这是取得了巨大进步，用make great progress“取得巨大进步”与前文语境相符。 16．句意：人们逐步改进数字系统。 后文提到“They created zero, decimals and negative numbers.”列举零、小数等发展过程，这是逐步改进数字系统，用step by step“逐步”与前文逻辑相一致。 17．句意：他们从小教孩子数字的重要性。 前文提到“Soon, these symbols became early numbers. Life became easier and clearer. Counting their food and money was no longer”人们能数食物和钱，生活变得更容易，更清楚，因此数字对生活是很重要的，用importance与前文的语境一致。 18．句意：如果我们正确使用它们，数字会很好地为我们服务。 根据前后句，数字会很好地为我们服务，应是在我们正确地使用它们的条件下，用if引导条件状语从句。 19．句意：如果我们忽视数字规则，我们会遇到许多问题。 后文提到“ignore number rules”忽视数字规则的后果是负面的“问题”。用problems与语境相符。 20．句意：让我们每天从小行动开始。 前文提到“Learning numbers well is learning to understand the world.”学好数字就是学会理解世界，因此要从学好数字这个小行动开始，用actions贴合实践语境。 21．C 22．B 23．A 24．D 25．B 【导语】本文是一篇说明文。主要介绍了ChatGPT需要消耗大量水资源来运行。 【详解】21．细节理解题。根据第一段“It can answer questions, tell stories and write articles.”可知，ChatGPT可以回答问题、讲故事和写文章。故选C。 22．词句猜测题。根据第二段“When it works, the computers in the data centres get very hot. Workers then have to use water to cool them down. ”可知，当它工作时，数据中心的计算机会变得非常热。工人们不得不用水给它们降温。因此，them指代的是数据中心的计算机。故选B。 23．推理判断题。根据第三段“When you ask ChatGPT 50 questions, it ‘drinks’ 500 millilitres (ml) of water.”可知，当你问ChatGPT 50个问题时，它会“喝”500毫升的水。由此可推算，问一个问题，喝水为：500÷50＝10 ml。故选A。 24．推理判断题。根据第四段“There are more than 8,000 data centres around the world. The number is still growing.”和第五段“AI uses a lot of water to ‘grow’. The world’s water may not be enough. Many people don’t have enough water to drink.”可知，未来会有越来越多数据中心，会消耗越来越多水，人们没有足够喝的水。由此可推断，我们不得不与AI“争夺”水源。故选D。 25．主旨大意题。根据“But it’s very ‘thirsty’, said a new study from Harvard University.”以及通读全文可知，文章主要说的是ChatGPT工作时需要大量的水。故选B。 26．A 27．B 28．B 29．C 30．B 【导语】本文由APP上呈现的广告引出我们的个人信息被企业收集和贩卖，进而提出我们应该高度重视和保护个人信息。 【详解】26．细节理解题。根据“Well, instead of paying with money, you’re paying by sharing your personal data (数据).”可知，说明用户通过“分享个人数据”来换取免费使用。故选A。 27．细节理解题。根据“Companies called ‘data  brokers’ collect your data—everything from your name, ... and then sell it to other brokers and businesses.”以及“The data is valuable.

Businesses can use the information from data brokers to target their ads. It means they will show their ads to the people who are most likely to be interested in their products or services.”可知，企业用数据来定位广告，意味着他们将把广告展示给最有可能对他们的产品或服务感兴趣的人；由此推知本段回答了为什么企业想要数据。故选C。 30．推理判断题。文章结尾提醒读者应学会保护个人信息，根据“If an app asks for ... consider saying ‘No’ first.”可知，是写给“App用户”的安全提示。故选B。 31．D 32．B 33．C 34．A 35．C 【导语】本文是一篇说明文，介绍了饼状图、折线图、条形图和维恩图这四种最常见图表的特点、适用场景及具体示例，以指导如何选择合适的图表来清晰展示数据。 【详解】31．推理判断题。根据“Let’s look at the four most common graph types”可知，文章介绍常见图表类型，与数学学习相关，故选D。 32．细节理解题。根据“Pie Chart、Line Graph、Bar Graph、Venn Diagram”可知，共提到4种图表，故选B。 33．细节理解题。根据“Line Graph: An excellent choice if you want to describe how something changes over time.

In order to learn about the changes of the students’ lives, Yangcheng Middle School did research. As the graph shows, it took the students 2 hours to finish homework before carrying out the “double reduction” policy, but now they spend 80 minutes doing their homework. What’s more, they used to spend only 30 minutes doing exercise, while they can have 60 minutes to do exercise now. The students think that they can have more free time to take part in some interesting activities such as playing football, playing the piano and drawing. In my opinion, the “double reduction” policy is good for us. I believe we can study happily because of the “double reduction” policy. 【详解】[总体分析] ①题材：本文是一篇材料作文； ②时态：以一般现在时为主； ③提示：注意语言准确，内容完整，语句通顺，语法正确，行文连贯，条理清晰。 [写作步骤] 第一步，详细介绍调查结果。 第二步，介绍学生们课余生活的变化。 第三步，表达自己的观点。 [亮点词汇] ①carry out 执行 ②used to do 过去常常 ③take part in 参加 ④be good for 对……有益 [高分句型] ①As the graph shows, it took the students 2 hours to finish homework before carrying out the “double reduction” policy, but now they spend 80 minutes doing their homework. （It takes sb.+时间+to do sth.句型结构） ②The students think that they can have more free time to take part in some interesting activities such as playing football, playing the piano and drawing.（that引导的宾语从句） 答案第1页，共2页 答案第1页，共2页 学科网（北京）股份有限公司 $
