These are called cross-references, and they are one of the most helpful features of any encyclopaedia. Their main job is to guide readers to other entries that contain related information. For example, if you are reading about elephants, a cross-reference might point you to “African wildlife” or “animal communication.” Cross-references are useful because knowledge is not made up of separate pieces. Everything in the world is connected in some way. When a reader follows a cross-reference, they begin to see these connections. This helps build a deeper understanding rather than just memorising isolated（孤立的）facts. A student who reads about the Roman army and then follows a cross-reference to “Roman engineering” will realise how military needs drove the development of roads and bridges. Moreover, cross-references save time. Without them, a reader might spend hours searching for related information. With them, the journey from one topic to another becomes smooth and natural. Many readers enjoy this kind of exploration, as it turns learning into an adventure（冒险）. Of course, editors must choose cross-references carefully. A bad cross-reference can send a reader to an unrelated article and cause confusion（困惑）. When done well, however, cross-references turn an encyclopaedia from a simple collection of facts into a web of knowledge that invites discovery. 1. What are cross-references in an encyclopaedia? 2. Why are cross-references useful for understanding a topic? 3. How do cross-references save time for readers? 4. What might happen if an editor chooses a bad cross-reference? 5. If you were reading about pandas, what cross-reference would you expect to see? Explain your choice. （2） 阅读短文，掌握大意，并回答以下问题。（共5小题；每小题2分，满分10分） How Encyclopaedia Editors Work Behind every good encyclopaedia is a team of hard-working editors. Their job begins long before the first book is printed. First, they decide which topics to include. This is not an easy task because there are millions of possible subjects. Editors must choose those that are most important and most likely to interest readers. Once the topic list is ready, editors invite experts to write the articles. These experts are usually professors or researchers who know their subjects very well. However, even experts can make mistakes, so editors check every article carefully. They look for incorrect facts, unclear explanations, and even spelling errors. They also make sure the language is suitable for the target audience. An encyclopaedia for children uses simpler words than one for adults. After the articles are written and checked, editors organise them in a logical order. Most modern encyclopaedias use alphabetical order, but some arrange topics by subject groups. Editors also add illustrations（插图）, maps, and cross-references to make the book more useful. The work does not stop after publication. Editors keep collecting new information so they can prepare updated editions（更新版本）. In this way, encyclopaedias remain current and continue to serve readers well for many years. 1. What is the first task of encyclopaedia editors? 2. Why do editors check articles even when experts have written them? 3. How do editors organise the articles in modern encyclopaedias? 4. What do editors do after a book is published? 5. Would you like to be an encyclopaedia editor one day? Why or why not? （3） 阅读短文，掌握大意，并回答以下问题。（共5小题；每小题2分，满分10分） Learning Through Encyclopaedia Quizzes（小测验） Many encyclopaedias now include quizzes and question boxes throughout their pages. These are not just for fun but actually help readers learn more effectively. When you read a passage and then answer a question about it, your brain works harder to recall the information. This process, called active recall（主动回忆）, strengthens（增强）your memory much better than passive（被动的）reading does. Quizzes also point out what you have missed. If you get an answer wrong, you realise that you did not understand that part fully. You can then go back and re-read the section with more attention. This cycle of reading, testing, and re-reading is a proven（经证实的）study method. Another benefit is that quizzes make reading more interesting. Instead of just looking at words on a page, readers become active participants（参与者）. They feel a sense of achievement when they get an answer right. This positive feeling encourages them to keep reading and learning. Some encyclopaedias place quizzes at the end of each chapter, while others scatter（分散） them throughout the text. Either way, they serve the same purpose of turning reading from a passive activity into an active conversation between the reader and the book. For students, this is one of the most effective ways to prepare for exams and retain（记住）knowledge long-term. 1. What is active recall according to the passage? 2. What happens when a reader gets a quiz answer wrong? 3. Why do quizzes make reading more interesting? 4. Where do some encyclopaedias place their quizzes? 5. Do you think quizzes in books are helpful for learning? Why or why not? 三、语法填空 （1） 阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空。（共 5 小题；每小题 1 分，满分 5 分） Choosing the Right Encyclopaedia When you walk into a library, you (1) __________ (see) many different encyclopaedias on the shelves.
