B 【解析】本文讲述战败逃亡的国王偶遇一位老妇人，老妇人借吃饭烫手的小事点拨国王做事不可急躁、要循序渐进的故事。 1. 句意：他很幸运，因为他看到不远处有一束光亮。 根据后文“reached a hut”，可知此处是小屋发出的光。star“星星”、stone“石头”、lake“湖”均不符合语境，light“光”符合。到小屋，其他选项不合逻辑。 2. 句意：老妇人以为他是军队里的士兵，便欢迎他进屋，还给他端了一盘热食。 前文国王战败逃亡，老妇人推测他来自军队，soldier“士兵”符合；teacher“老师”、cook“厨师”、farmer“农民”均和军队无关。 3. 句意：国王太饿了，以至于他立刻把手指伸向热食。 后文国王急切地触碰食物，体现他饥饿；hungry“饥饿的”符合。tired“疲惫的”、angry“生气的”、excited“兴奋的”均不契合语境。 4. 句意：热食烫伤了他的手指，使他掉落了一些米饭。 后文出现“burnt your fingers”，对应此处热食烫伤手指，burnt“烫伤” 符合；cut“割破”、broke“弄坏”、hit“击打”均不符合热食带来的伤害。 5. 句意：哦，你和你的国王一样急躁。 后文多次提到国王做事急躁，impatient“急躁的，没耐心的”符合；unhappy“不开心的”、unkind“不友善的”、impolite“不礼貌的”均不符合后文核心主题。 6. 句意：亲爱的孩子，我们的国王有一个攻占敌人所有堡垒的宏大计划。 后文讲国王的作战安排，plan“计划”符合；surprise“惊喜”、secret“秘密”、role“角色”均不契合。 7. 句意：然而，他不在意所有小堡垒，只专注于大堡垒。 根据句意，国王只将注意力放在大堡垒上，focuses on“专注于” 符合；helps with“帮助”、works with“共事”、counts on“依靠”逻辑不通。 8. 句意：就像你弄掉食物一样，国王急于快速击败敌人的急躁导致了军队人员的损失。 此处指急躁的性格造成、导致士兵损失，caused“导致” 符合；covered“覆盖”、avoided“避免”、stopped“阻止”语义相反。 9. 句意：同样地，国王应当先攻占小堡垒、巩固阵地。 前文用吃饭烫手类比国王的作战问题，是同理类比，Similarly“同样地”符合；Differently“不同地”、Strangely“奇怪地”、Surprisingly“令人惊讶地”不符合类比逻辑。 10. 句意：听到这些，国王意识到了自己的错误，明白了人做事要有耐心，三思而后行。 老妇人点醒了国王，国王认识到自身错误，mistake“错误”符合；position“位置”、order“命令”、promise“承诺”均不符合语境。 九、阅读理解 A 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 Chart It’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 Graph An 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. Colorful Bar Graph A colorful bar graph can also show changes over time. However, it’s more direct to make comparisons 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 A Venn Diagram features two overlapping circles. It’s perfect for sorting 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. Venn Diagram 1. Where can we probably find the passage? A. In a historical novel. B. In a maths textbook. C. In a sports newspaper. D. In a tour guide. 2. If you want to show how something changes over time and big differences, which graph would be a good choice? A. Pie chart B. Colorful Bar Graph C. Line Graph D. Venn Diagram 3. 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 4. If you want to show how different activities, such as sleeping, studying, fun, and sports, make up the 24 hours in your day, which graph is the best choice? A. Pie Chart B. Line Graph C. Colorful Bar Graph D. Venn Diagram 5. What is the main purpose of this passage? A. To tell people about the use of data. B. To introduce some helpful data display methods. C.

It makes data clear.”可知，文章围绕数据图表展开，这类内容通常出现在数学课本中，故选B。 2. 细节理解题。根据“Line Graph... An excellent choice if you want to describe how something changes over time. It is also good for showing big differences.”可知，折线图适合展示随时间的变化和较大差异，故选C。 3. 词句猜测题。根据“Plants with both go in the middle where the circles overlap.”可知，“overlapping circles” 指的是两个圆互相覆盖部分区域，选项A “that covers part of another circle”符合语境，故选A。 4. 细节理解题。根据“Pie Chart... It’s good for showing a certain part of a whole and the proportion of each part.”可知，饼图适合展示整体中各部分的比例，“不同活动占一天 24 小时的比例”属于此类场景，故选A。 5. 主旨大意题。根据“Let’s look at the four most common graph types”及全文对各类图表的介绍可知，文章的主要目的是介绍实用的数据展示方法，故选B。 B By 2030, the world’s data (数据) centers are expected to use more than double the electricity they use today. AI is the main driver. It forces countries to look for new ways to solve the big problem. China is leading the way by putting data centers under the sea as a greener solution. In December 2022, Hainan became home to China’s first underwater data center. This was followed by a more advanced (先进的) project in Shanghai in 2025. AI servers give off heat while working, making the temperature rise. If the heat isn’t taken away in time, the servers won’t run well or even break down. On-land data centers have to use up to 40% of their electricity just for cooling AI servers. Underwater data centers, like the one in Shanghai, use pipes to pump (输送) seawater. Seawater goes through the radiators on the back of the servers. It takes in heat and carries it away. The sea temperature is about 15℃, perfect for natural cooling. In this way, the electricity is saved. An assessment (评估) from the China Academy of Information and Communications Technology shows the underwater data center uses at least 30% less electricity than on-land data centers thanks to natural cooling. Underwater data centers can also reduce land usage by 80%. And the one in Shanghai offers another benefit: it will get more than 95% of its electricity from a kind of renewable energy—wind energy. And the use of tidal (潮汐) and wave energy is also taken into consideration. China’s efforts in developing underwater data centers show its promise to create low-carbon digital infrastructure (低碳数字基础设施). The act not only helps reduce the environmental influence of AI, but also could set a new standard for sustainable computing (可持续算力) worldwide. 1. What is the main reason for China to develop underwater data centers? A. To provide more electricity for AI servers directly. B. To reduce the cost of building on-land data centers. C. To solve the problem of high energy use caused by AI. D. To increase the speed of internet connections worldwide. 2. How does an underwater data center cool AI servers? A. It uses seawater to cool AI servers naturally. B. It uses air conditioners for cooling AI servers. C. It depends on wind energy to power its cooling. D. It is connected with tidal and wave energy for cooling. 3. Which of the following is TRUE according to paragraph 4 and paragraph 5? A. B. C. D. 4. What would you do next if you were the developer of China’s underwater data centers according to the passage? A. Close all the on-land data centers to save electricity in the near future. B. Focus on developing on-land data centers instead of underwater data centers. C. Cut down the cost of research and development since the projects are successful. D. Explore the use of tidal and wave energy to further improve sustainable computing. 【答案】1. C 2. A 3. B 4. D 【解析】本文是一篇说明文，主要介绍了中国为解决AI带来的高能耗问题，发展水下数据中心的相关情况，包括其冷却原理、节能优势、用地优势及可持续能源利用等。 1. 根据原文第一段“AI is the main driver. It forces countries to look for new ways to solve the big problem. China is leading the way by putting data centers under the sea...”可知，中国发展水下数据中心的主要原因是解决AI导致的高能耗问题。 2. 根据原文第四段“Underwater data centers, like the one in Shanghai, use pipes to pump seawater. Seawater goes through the radiators on the back of the servers. It takes in heat and carries it away.”可知，水下数据中心利用海水自然冷却AI服务器。 3. 根据原文第四段“the underwater data center uses at least 30% less electricity than on-land data centers”和第五段“Underwater data centers can also reduce land usage by 80%.”可知，水下数据中心用电更少、用地更少，与选项B的图表信息一致。 4. 根据原文第五段“And the use of tidal and wave energy is also taken into consideration.”可知，作为开发者，下一步可探索潮汐和波浪能的使用，进一步提升可持续算力。 C 阅读配对 左栏是五名学生在生活中遇到的问题，右栏是七条建议。请为每位学生匹配最合适的建议，并在答题卡上将对应选项选黑。选项中有两项为多余项。 6 My mum didn’t agree to buy another model racing car for me.

B By 2030, the world’s data (数据) centers are expected to use more than double the electricity they use today. AI is the main driver. It forces countries to look for new ways to solve the big problem. China is leading the way by putting data centers under the sea as a greener solution. In December 2022, Hainan became home to China’s first underwater data center. This was followed by a more advanced (先进的) project in Shanghai in 2025. AI servers give off heat while working, making the temperature rise. If the heat isn’t taken away in time, the servers won’t run well or even break down. On-land data centers have to use up to 40% of their electricity just for cooling AI servers. Underwater data centers, like the one in Shanghai, use pipes to pump (输送) seawater. Seawater goes through the radiators on the back of the servers. It takes in heat and carries it away. The sea temperature is about 15℃, perfect for natural cooling. In this way, the electricity is saved. An assessment (评估) from the China Academy of Information and Communications Technology shows the underwater data center uses at least 30% less electricity than on-land data centers thanks to natural cooling. Underwater data centers can also reduce land usage by 80%. And the one in Shanghai offers another benefit: it will get more than 95% of its electricity from a kind of renewable energy—wind energy. And the use of tidal (潮汐) and wave energy is also taken into consideration. China’s efforts in developing underwater data centers show its promise to create low-carbon digital infrastructure (低碳数字基础设施). The act not only helps reduce the environmental influence of AI, but also could set a new standard for sustainable computing (可持续算力) worldwide. 1. What is the main reason for China to develop underwater data centers? A. To provide more electricity for AI servers directly. B. To reduce the cost of building on-land data centers. C. To solve the problem of high energy use caused by AI. D. To increase the speed of internet connections worldwide. 2. How does an underwater data center cool AI servers? A. It uses seawater to cool AI servers naturally. B. It uses air conditioners for cooling AI servers. C. It depends on wind energy to power its cooling. D. It is connected with tidal and wave energy for cooling. 3. Which of the following is TRUE according to paragraph 4 and paragraph 5? A. B. C. D. 4. What would you do next if you were the developer of China’s underwater data centers according to the passage? A. Close all the on-land data centers to save electricity in the near future. B. Focus on developing on-land data centers instead of underwater data centers. C. Cut down the cost of research and development since the projects are successful. D. Explore the use of tidal and wave energy to further improve sustainable computing.
