Covering over 5.5 million square kilometers, it spreads across nine countries in South America, including Brazil and Peru. This amazing natural wonder is home to an unbelievable variety of life. Scientists say there are more than 40,000 plant species, 3,000 fish species, and 1,300 bird species living there. Many of these species can only be found in the Amazon. The rainforest also plays a key role in controlling the world’s climate. Its trees absorb large amounts of carbon dioxide, a gas that causes global warming. However, the Amazon is in danger now. Every year, lots of trees are cut down for wood or to make space for farms. This not only destroys animal habitats but also affects the world’s oxygen supply. 16.Why is the Amazon Rainforest called the “lungs of the Earth”? A. It has many trees. B. It produces much oxygen. C. It absorbs carbon dioxide. D. It is very large. 17.How many bird species live in the Amazon Rainforest according to the passage? A. Over 40,000. B. About 3,000. C. Over 1,300. D. 5.5 million. 18.Which country is NOT mentioned as part of the Amazon Rainforest’s area? A. Brazil. B. Peru. C. China. D. None of the above. 19.What is the danger facing the Amazon Rainforest? A. Too many tourists. B. Lack of water. C. Tree cutting. D. Climate change. 20.What happens when trees are cut down in the Amazon? A. Animal habitats are destroyed. B. Oxygen supply is affected. C. Both A and B. D. Nothing serious. 【答案】16.B；17.C；18. C；19. C；20. C 【详解】 16．根据原文第一段 “The Amazon Rainforest is often called the ‘lungs of the Earth’ because it produces more than 20% of the world’s oxygen.” 可知，亚马逊雨林被称为 “地球之肺” 是因为它产生了世界上 20% 以上的氧气，故选 B。 17.原文第二段明确提到 “Scientists say there are more than 40,000 plant species, 3,000 fish species, and 1,300 bird species living there.”，其中鸟类物种数量是 1300 多种，故选 C。 18.第一段指出雨林 “spreads across nine countries in South America, including Brazil and Peru”，提到了巴西和秘鲁，未提及中国，故选 C。 19.根据第三段 “Every year, lots of trees are cut down for wood or to make space for farms.” 可知，雨林面临的危险是大量树木被砍伐，故选 C。 20. 原文最后一句明确说明 “this not only destroys animal habitats but also affects the world’s oxygen supply”，即树木被砍伐既破坏动物栖息地，又影响氧气供应，A 和 B 均正确，故选 C。 B The Northern Lights The Northern Lights, also known as Aurora Borealis, is one of the most beautiful natural wonders. It appears in the night sky near the North Pole, usually from September to March. The lights look like colorful curtains dancing across the sky—they can be green, pink, purple, or even red. What causes this amazing sight? It starts with the sun. The sun sends out charged particles (带电粒子) into space. When these particles hit the Earth’s magnetic field (磁场), they are pulled toward the North and South Poles. As the particles collide (碰撞) with gas molecules (分子) in the Earth’s atmosphere, light is produced. Different gases create different colors: oxygen mostly makes green light, while nitrogen (氮气) creates pink or purple. To see the Northern Lights, you need dark skies and clear weather. The best places to watch them are in northern countries like Norway, Sweden, and Iceland. Many tourists travel to these places in winter just to catch a glimpse of this magical natural show. Some lucky viewers even say the lights look like they are “singing” or “moving to music”—though that’s just the magic of the moment! 21.What is another name for the Northern Lights? A. Aurora Borealis. B. Magnetic Field. C. Gas Molecules. D. Northern Pole. 22.When can people usually see the Northern Lights? A. From March to September. B. From September to March. C. Only in winter. D. All year round. 23.What causes the Northern Lights? A. The Earth’s atmosphere. B. Colorful curtains in the sky. C. Collisions between sun particles and gas molecules. D. Tourists’ cameras. 24.Which gas mostly creates green light in the Northern Lights? A. Nitrogen. B. Oxygen. C. Carbon dioxide. D. Hydrogen. 25.What do people need to see the Northern Lights? A. Dark skies and clear weather. B. A lot of money. C. Special cameras. D. Warm clothes. 【答案】21. A；22. B；23. C；24. B；25.A 【详解】21.原文第一段首句明确提到 “The Northern Lights, also known as Aurora Borealis”，即北极光的另一个名字是 Aurora Borealis，故选 A。 22.根据第一段 “it appears in the night sky near the North Pole, usually from September to March” 可知，北极光通常在 9 月到 3 月出现，故选 B。 23.第二段解释了成因：太阳发出的带电粒子撞击地球磁场后被拉向两极，与大气中的气体分子碰撞产生光，即北极光是由太阳粒子和气体分子的碰撞形成的，故选 C。 24. 原文第二段提到 “Different gases create different colors: oxygen mostly makes green light”，即氧气主要产生绿色的光，故选 B。 25.根据第三段 “To see the Northern Lights, you need dark skies and clear weather” 可知，观看北极光需要黑暗的天空和晴朗的天气，故选 A。 三、补全对话（共5小题，每小题2分，共10分） 根据对话内容，用恰当的词补全对话。 Tour Guide (G): Good morning, everyone!

S: Thank you! This trip is really 30. ______ remembering. 【答案】26.heard of 27. is famous for 28. follow 29. look around 30.worth 【详解】26“heard of” 是固定短语，意为 “听说过”，符合导游询问学生是否了解大峡谷的语境。此处强调 “知晓其存在”，而非 “听动作”“看动作” 或 “谈论”，故填 “heard of”。 27.“is famous for” 为常用表达，意为 “因…… 而著名”，承接上文学生 “为什么出名” 的提问，后文紧接着说明规模和岩石等出名原因，逻辑严密，故填 “is famous for”。 28.“follow the rules” 是固定短语 “遵守规则”，导游提醒学生 “不要偏离路线”，本质是要求遵守游览规定，“follow” 在此处表 “遵从”，符合场景需求，故填 “follow”。29.“look around” 意为 “环顾四周；欣赏景色”，结合 “先…… 再拍照” 的游览逻辑，“look around” 能准确表达 “先欣赏景色” 的含义，而非 “寻找”“照顾” 或 “查阅”，故填 “look around”。 30.“be worth doing” 是固定结构，意为 “值得做某事”，学生表达对旅行的认可，“值得铭记” 是自然的情感抒发，“worth” 与 “remembering” 搭配合理，故填 “worth” 四、短文填空（共10小题，每小题1分，共10分） The Northern Lights, or Aurora Borealis, is a magical natural wonder that 31. ______ (appear) in the night sky near the North Pole.

It lies on the border between Zambia and Zimbabwe in Africa. Victoria Falls is famous for its huge size and loud sound. When the water falls down from a high place, it makes a big noise that can be heard far away. The water also creates thick mist, and sometimes you can see rainbows in the mist. It looks really beautiful. I like Victoria Falls because it shows the power and beauty of nature. It makes me feel small but happy. I hope I can visit it one day and see its greatness with my own eyes. 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 编写说明：本套【山东专用】《同步单元AB卷》紧扣《英语 基础模块3》（高教版2023版）教材，以教材单元为基准精准覆盖核心考点，并紧密贴合山东省真题题型。A卷为考点梳理卷，侧重考点分层突破；B卷为单元测试卷，强化综合能力检测，助力师生高效把握区域教学重点，提升应试能力与知识应用水平。 本卷是Unit 5 Natural Wonders in the World的单元测试卷，主要考查词汇、词组、句式句型、情景交际功能话题、阅读能力和书面表达能力。 Unit 5 Natural Wonders in the World B卷·单元测试卷 考试时间：60分钟 满分：100分 班级 姓名 学号 成绩 一、语法和词汇（共15小题，每小题2分，共30分） 从每小题所给的四个选项中，选出一个可以填入空白处的最佳选项。 1.
