It is not just a beautiful stone; it is also a window into the past. Amber is formed from the resin of ancient trees. When the resin is exposed to air and sunlight, it hardens over millions of years. During this process, small creatures, plants, and even air bubbles can become trapped inside. These trapped objects are like time capsules. They provide scientists with valuable information about life on Earth millions of years ago. For example, a piece of amber found in Southeast Asia contains the tail of a dinosaur with feathers. This discovery proved that some dinosaurs had feathers, which changed people's understanding of these ancient creatures. Another piece of amber from Northern Europe holds a flower that no longer grows in that area. It shows that the climate there was different in the past. Amber has also helped scientists discover new species. In a piece of African amber, researchers found 13 ants that belong to a completely new species. Before this discovery, scientists believed that ants originated in the northern half of the Earth. But this African species proved that ants might have spread to different parts of the world earlier than thought. Today, amber is still being studied by scientists. They hope that future discoveries in amber will help them unlock more secrets of nature. Amber reminds us that nature has many stories to tell, and we just need to take the time to listen. 细节理解 根据短文内容，选择最佳答案 （ ）1.What is amber formed from? A. The bones of ancient animals. B.

It is called the boiling river because its water is so hot that it can boil small animals. The river is about 6.4 kilometers long and 25 meters wide. The water temperature reaches up to 93°C, which is hot enough to cook an egg. For centuries, the local people have known about the boiling river. They considered it a sacred place and told stories about it. But scientists didn't believe in its existence until 2011, when a geoscientist named Andrés Ruzo found it. Ruzo was fascinated by the river and spent years studying it. Scientists are still trying to figure out why the river is so hot. Some think that it is heated by magma deep underground. Others believe that there are chemicals in the river that produce heat when they react with water. However, no one has found the exact cause yet. The boiling river is not only a natural wonder but also an important ecosystem. Many unique plants and animals live near the river. But it is also in danger. Deforestation and human activities are threatening the river's environment. Scientists and local people are working together to protect this amazing natural wonder. （ ）1.Where is the boiling river located? A.In Africa. B. In Asia. C. In the Amazon Rainforest. D. In Europe. （ ）2.What is the temperature of the boiling river? A. Up to 93°C. B. Up to 100°C. C. Up to 80°C. D. Up to 70°C. （ ）3.When did scientists confirm the existence of the boiling river? A. In 2000. B. In 2011. C. In 2015. D. In 2020. （ ）4.What do scientists think causes the river to be hot? A.Magma or chemical reactions. B. Sunlight. C. Human activities. D.

When the resin flows out of the trees, it can trap small plants, insects, and even air bubbles. Over millions of years, the resin hardens and becomes amber. These trapped objects are like time capsules that can keep things from the past. Scientists have found many valuable things in amber. For example, they have found dinosaur feathers, ancient insects, and rare plants. These discoveries help scientists study ancient life and learn about the climate and environment of the past. Amber is not only a beautiful stone but also an important scientific treasure. It reminds us that nature has many stories to tell, and we need to protect it to discover more secrets. 答案与解析 模块一 课后分层巩固练习 一、词汇夯实 基础层 1.help 2. kindness 3. raised 4. patience 5. friendship 6. willingness 7. kind 8. volunteers 9. donated 10. trouble 11. joined 12. cleaning 13. brought 14. touched 15. provide 16. lend 17. courage 18. caring for 19. contribution 20. realize 解析：本题聚焦单元核心词汇，所有词汇均对应教材Reading、Developing ideas模块的重点，强化拼写、词义及搭配掌握。 提高层 1.discovery 2. curiosity 3. strengthen 4. exploration 5. adaptation 解析：第3题“strengthen”虽为衍生词，但属于常用变形，“strong（形容词）→strengthen（动词，加强）”，贴合教材词汇衍生教学逻辑；本题聚焦词性转换，强化词汇灵活运用能力。 拓展层 1.discovered 2. exploring 3. discoveries 4. interact 5. unsolved 6. curiosity 解析：第3题“make a difference”补充语境隐含支撑，结合教材Reading中短语原句，降低应用门槛；整个题目贴合“动物交流”的自然探索主题，通过上下文辅助理解，符合拓展层要求。 二、语法攻坚 基础应用 1.that 2. if/whether 3. if/whether 4. that 5. if/whether 6. if/whether 7. if/whether 8. that 9. if/whether 10. whether 解析：第10题用“about plant growth”，将实验场景与单元“自然探索”主题绑定；严格遵循单元核心语法，that表陈述事实，if/whether表疑问，但if更口语化；而whether可与or not连用，全覆盖教材Grammar模块考点。 语境综合 1.that 2. if/whether 3. if/whether 4. that 5. if/whether 6. if/whether 7. that 8. that 9. if/whether 10. that 解析：if接名词性从句时表示“是否”，可与whether互换，但if更口语化。题目内容贴合“自然保护”主题，确保语法应用与主题高度匹配。 错题诊断 1.B 错误原因分析：本题考查that/if/whether引导的宾语从句。句意为“我不知道他是否会加入自然探索队”，表不确定用if/whether。A.that无疑问含义，用于陈述事实；C.what和D.who在从句中需作主语或宾语，此处从句成分完整，均不符合单元语法核心考点。 2.C 错误原因分析：句意为“她告诉我她在森林里看到了一只稀有鸟类”，陈述事实用that。A.if和B.whether表“是否”，D.when表“何时”，均不符合“陈述自然探索相关事实”的语境，与单元语法应用场景不符。 3.B 错误原因分析：句意为“科学家们正试图查明这种古老植物是否能被复活”，表疑问用if/whether。A.that用于陈述事实；C.what和D.which需在从句中作成分，此处从句完整；且单元语法重点是表疑问或陈述事实。 三、阅读提升 细节理解 1.B 2.

It was memorable. We started early. Along the way, we saw many rare plants and heard birds singing. Our guide told us how these plants adapt to the environment.
