The table above shows how one encyclopaedia divides its content into five main subjects, each covering a specific area of knowledge. By understanding the structure of an encyclopaedia, readers can quickly locate the information they need without wasting time flipping through irrelevant pages. This is especially important for students who are doing research projects or preparing for exams. The encyclopaedia covers a wide range of topics, from famous artists and their masterpieces to the latest scientific discoveries and space exploration. Each section is carefully organized so that readers can find detailed information about their chosen subject. For example, if you are interested in learning about ancient civilizations or important historical events, you can turn to the history section. If you prefer to learn about the natural world, the living world section offers rich content about animals, plants, and even dinosaurs. The human body section is particularly useful for those who want to understand how our bodies function and how to maintain good health. With such a well-organized structure, this encyclopaedia serves as a perfect starting point for anyone who wants to explore the world of knowledge. 36. Which section of the encyclopaedia would you read to find information about the Great Wall? A. Culture and arts B. The living world C. History and society D. Human body 37. If you want to learn about how the heart works, which pages should you turn to? A. Pages 5-20 B. Pages 21-45 C. Pages 46-70 D. Pages 96-115 38. Which subject covers both plants and dinosaurs? A.

A. 115 B. 110 C. 120 D. 95 B In June 2026, Chinese scientists announced an exciting discovery — a new feathered dinosaur species named Changzhousaurus sinensis (中华常州龙). The fossil was found in Liaoning Province and is about 120 million years old. It is exceptionally well-preserved, with clear imprints of extensive feathers surrounding its skeleton. What makes this dinosaur special is its unique combination of features. It is the only known pennaraptoran dinosaur that simultaneously developed both large foot feathers and exceptionally long, fan-shaped tail feathers. It had around 16 tail feathers, somewhat similar to a peacock's plumage. In terms of classification, it belongs to the dromaeosaurid family of theropod dinosaurs, making it a close relative of the Velociraptor and Microraptor. Scientists noted that this unique morphological combination — featuring large forelimb wing feathers alongside well-developed foot and tail feathers — has never been seen in any previously discovered dinosaur. This discovery provides new physical evidence to help understand the evolutionary path of dinosaur flight. The research was led by Xu Xing, an academician of the Chinese Academy of Sciences, who has named more than 80 dinosaur species. His popular science book Dinosaurs Flying to the Blue Sky was once included in Chinese primary school textbooks. The species was named after Changzhou, a city in Jiangsu Province, in recognition of its long-standing efforts to promote dinosaur science popularization. 41. Where was the fossil of Changzhousaurus sinensis found? A. In Changzhou. B. In Liaoning. C. In Beijing. D. In Gansu. 42. What makes Changzhousaurus sinensis unique among known dinosaurs? A. It is the largest dinosaur ever found. B. It had no feathers at all. C. It is the only known dinosaur with both large foot feathers and long fan-shaped tail feathers. D. It could fly like modern birds. 43. What does the underlined word "plumage" in Paragraph 2 mean? A. Skeleton. B. Feather covering. C. Foot structure. D. Tail bone. 44. Why was the new dinosaur named after Changzhou? A. Because Changzhou has the most dinosaur fossils. B. Because the dinosaur was discovered in Changzhou. C. Because Changzhou has promoted dinosaur science popularization. D. Because Changzhou is the capital of China. 45. What is the main purpose of the passage? A. To introduce a newly discovered feathered dinosaur species. B. To explain why dinosaurs died out. C. To compare different types of encyclopaedias. D. To describe the history of Liaoning Province. C In 2023, the National Library of China launched the Yongle Dadian High-Definition Image Database (《永乐大典》高清影像数据库). For the first time, 40 volumes of this ancient encyclopaedia are available online for free. The database was built with support from ByteDance's ancient book protection fund. The Yongle Dadian was completed in 1408 during the Ming Dynasty. It contained about 22,877 volumes and around 370 million Chinese characters, making it the largest encyclopaedia in the world. However, most of the original copies were lost over the centuries due to wars, fires and other disasters. Today, only about 400 volumes survive worldwide, less than 4% of the original work. The new database not only presents high-definition images of the encyclopaedia, but also includes knowledge indexing (知识标引) for some content. Users can search for specific topics, read the original text, and zoom in to see details of the ancient handwriting. In 2026, the database won the China Publishing Government Award, showing the importance of using technology to preserve cultural heritage. Thanks to digital technology, people can now read these precious books that were once only visible in museums. As one expert said, "Technology gives ancient books new life and allows everyone to access the wisdom of the past." 46. When was the Yongle Dadian High-Definition Image Database launched? A. In 1408. B. In 2023. C. In 2026. D. In 2001. 47. How many volumes of the original Yongle Dadian survive today? A. About 22,877. B. About 400. C. About 370 million. D. About 4. 48. What can users do with the database according to Paragraph 3? A. Only look at the cover of the books. B. Search for topics and read the original text. C. Edit the content of the ancient books. D. Buy printed copies of the encyclopaedia. 49. What does the underlined phrase "zoom in" in Paragraph 3 most probably mean? A. Look more closely. B. Turn the page. C. Write a note. D. Copy the text. 50. What is the writer's main message in the passage? A. The Yongle Dadian is no longer important. B. Digital technology helps preserve and share ancient knowledge. C. Only experts can read ancient books. D. The Yongle Dadian was the first encyclopaedia in China. 第二节 阅读填空(本大题共5小题，每小题1分，共5分) Online encyclopaedias are wonderful tools for learning, but you need to use them wisely. 51 Here are some tips to help you get the most out of them. First, always check the source of the information. 52 If you find information on Wikipedia, look at the references at the bottom of the page. Reliable articles usually have many sources. Second, compare information from different places. Don't rely on just one article. 53 This is especially important for school projects, where accuracy matters a lot. Third, be careful with AI-generated content. Some new tools like Grokipedia use AI to write articles. 54 Always double-check AI-generated information with trusted sources like Encyclopaedia Britannica. Finally, remember that encyclopaedias are starting points, not finishing points. 55 Use them to understand the basics, then look for more detailed books and articles to deepen your knowledge. A. Not all information online is accurate. B. Who wrote the article and when was it last updated? C. They can be helpful, but AI sometimes makes mistakes. D. They give you an overview, but they cannot cover everything in depth. E. Just because something is online does not mean it is true. F. Read the same topic on two or three different websites. 第三节 信息匹配 (本大题共5小题，每小题1分，共5分) 下面的材料A-F分别介绍了不同的百科全书或知识工具，请根据五位同学的需求，帮助他们选出最适合的工具，并将其标号填入题前括号内。 56 .

First, always check the source of the information. 52 If you find information on Wikipedia, look at the references at the bottom of the page. Reliable articles usually have many sources. Second, compare information from different places. Don't rely on just one article. 53 This is especially important for school projects, where accuracy matters a lot. Third, be careful with AI-generated content. Some new tools like Grokipedia use AI to write articles. 54 Always double-check AI-generated information with trusted sources like Encyclopaedia Britannica. Finally, remember that encyclopaedias are starting points, not finishing points. 55 Use them to understand the basics, then look for more detailed books and articles to deepen your knowledge. A. Not all information online is accurate. B. Who wrote the article and when was it last updated? C. They can be helpful, but AI sometimes makes mistakes. D. They give you an overview, but they cannot cover everything in depth. E. Just because something is online does not mean it is true. F. Read the same topic on two or three different websites. 第三节 信息匹配 (本大题共5小题，每小题1分，共5分) 下面的材料A-F分别介绍了不同的百科全书或知识工具，请根据五位同学的需求，帮助他们选出最适合的工具，并将其标号填入题前括号内。 56 .

The fossil was found in Liaoning Province and is about 120 million years old. It is exceptionally well-preserved, with clear imprints of extensive feathers surrounding its skeleton. What makes this dinosaur special is its unique combination of features. It is the only known pennaraptoran dinosaur that simultaneously developed both large foot feathers and exceptionally long, fan-shaped tail feathers. It had around 16 tail feathers, somewhat similar to a peacock's plumage. In terms of classification, it belongs to the dromaeosaurid family of theropod dinosaurs, making it a close relative of the Velociraptor and Microraptor. Scientists noted that this unique morphological combination — featuring large forelimb wing feathers alongside well-developed foot and tail feathers — has never been seen in any previously discovered dinosaur. This discovery provides new physical evidence to help understand the evolutionary path of dinosaur flight. The research was led by Xu Xing, an academician of the Chinese Academy of Sciences, who has named more than 80 dinosaur species. His popular science book Dinosaurs Flying to the Blue Sky was once included in Chinese primary school textbooks. The species was named after Changzhou, a city in Jiangsu Province, in recognition of its long-standing efforts to promote dinosaur science popularization. 41. Where was the fossil of Changzhousaurus sinensis found? A. In Changzhou. B. In Liaoning. C. In Beijing. D. In Gansu. 42. What makes Changzhousaurus sinensis unique among known dinosaurs? A. It is the largest dinosaur ever found. B. It had no feathers at all. C. It is the only known dinosaur with both large foot feathers and long fan-shaped tail feathers. D. It could fly like modern birds. 43. What does the underlined word "plumage" in Paragraph 2 mean? A. Skeleton. B. Feather covering. C. Foot structure. D. Tail bone. 44. Why was the new dinosaur named after Changzhou? A. Because Changzhou has the most dinosaur fossils. B. Because the dinosaur was discovered in Changzhou. C. Because Changzhou has promoted dinosaur science popularization. D. Because Changzhou is the capital of China. 45. What is the main purpose of the passage? A. To introduce a newly discovered feathered dinosaur species. B. To explain why dinosaurs died out. C. To compare different types of encyclopaedias. D. To describe the history of Liaoning Province. 【答案】41. B 42. C 43. B 44. C 45. A 【导语】本文介绍了2026年6月中国科学家宣布发现的一种新的有羽恐龙物种——中华常州龙，该发现为理解恐龙飞行的演化路径提供了新的物理证据。 41. 细节理解题。根据"The fossil was found in Liaoning Province"可知，化石是在辽宁省被发现的。故选B。 42. 细节理解题。根据"It is the only known pennaraptoran dinosaur that simultaneously developed both large foot feathers and exceptionally long, fan-shaped tail feathers"可知，它是已知唯一同时拥有大型脚部羽毛和超长扇形尾羽的恐龙。故选C。 43. 词句猜测题。根据前文"16 tail feathers, somewhat similar to a peacock's"可知，plumage指"羽毛覆盖物"，与peacock（孔雀）的羽毛相对应。故选B。 44. 细节理解题。根据"in recognition of its long-standing efforts to promote dinosaur science popularization"可知，以常州命名是为了表彰常州长期以来推广恐龙科普的努力。故选C。 45. 主旨大意题。全文主要介绍了一种新发现的有羽恐龙物种——中华常州龙，包括其发现地点、独特特征和命名原因。故选A。 C In 2023, the National Library of China launched the Yongle Dadian High-Definition Image Database (《永乐大典》高清影像数据库). For the first time, 40 volumes of this ancient encyclopaedia are available online for free. The database was built with support from ByteDance's ancient book protection fund. The Yongle Dadian was completed in 1408 during the Ming Dynasty. It contained about 22,877 volumes and around 370 million Chinese characters, making it the largest encyclopaedia in the world. However, most of the original copies were lost over the centuries due to wars, fires and other disasters. Today, only about 400 volumes survive worldwide, less than 4% of the original work. The new database not only presents high-definition images of the encyclopaedia, but also includes knowledge indexing (知识标引) for some content. Users can search for specific topics, read the original text, and zoom in to see details of the ancient handwriting. In 2026, the database won the China Publishing Government Award, showing the importance of using technology to preserve cultural heritage.

First, always check the source of the information. 52 If you find information on Wikipedia, look at the references at the bottom of the page. Reliable articles usually have many sources. Second, compare information from different places. Don't rely on just one article. 53 This is especially important for school projects, where accuracy matters a lot. Third, be careful with AI-generated content. Some new tools like Grokipedia use AI to write articles. 54 Always double-check AI-generated information with trusted sources like Encyclopaedia Britannica. Finally, remember that encyclopaedias are starting points, not finishing points. 55 Use them to understand the basics, then look for more detailed books and articles to deepen your knowledge. A. Not all information online is accurate. B. Who wrote the article and when was it last updated? C. They can be helpful, but AI sometimes makes mistakes. D. They give you an overview, but they cannot cover everything in depth. E. Just because something is online does not mean it is true. F. Read the same topic on two or three different websites. 【答案】51. E 52. B 53. F 54. C 55.
