🌳 8年级英语探究式阅读学案：解码树木的秘密 Topic: The Memories of Trees 🧭 第一步：观察与预测 (Pre-reading: Observe & Predict) 探究任务： 在阅读文字之前，请仔细观察图片并思考： 1. Look at the title and the picture. What do you think "memories of trees" are? · My guess: ___________________________________________________ 2. Look at the diagram (插图). Can you find these three parts? · [ ] A black scar (黑色伤痕) · [ ] Wide rings (宽环) · [ ] Narrow rings (窄环) 🔍 第二步：快速扫读 (Fast Reading: Structure & Main Idea) 探究任务： 快速阅读全文，理清文章脉络，完成匹配。 Match the paragraph with its main idea (匹配段落大意): · Paragraph 1-2: ______ A. How tree rings help us understand human history. · Paragraph 3: ______ B. Introduction to tree rings and what they tell about climate. · Paragraph 4: ______ C. How tree rings record natural disasters like fires. 💡 第三步：深度探究 (In-depth Reading: How it works) 探究任务： 细读课文，探究科学家是如何通过树木的“年轮”读取信息的。 1. 气候之谜 (The Secret of Climate) 阅读第5-12行，完成逻辑链： · Feature (特征): Wide rings $\rightarrow$ Meaning: The tree grew well with enough ______ and ______. · Feature (特征): Narrow rings $\rightarrow$ Meaning: It didn't ______ enough; it was a dry season. 2. 灾难印记 (The Record of Disasters) 阅读第13-20行，回答问题： · Observation: Scientists find a black area on a tree ring. · Inquiry: What happened to the forest? ________________________ · Evidence: By counting the rings from the black area, what two questions can they answer? 1. ______________________________________________ 2. ______________________________________________ 3. 历史见证 (The Witness of History) 阅读第21-27行，填充关键信息： · Historical Discovery: A Viking village in Canada was found. · Key Time: It was built in the year ______. · Method: Scientists used ____________ patterns and the ____________ of each ring. 🛠️ 第四步：语言探究 (Language Inquiry: Expressing Results) 探究任务： 文章多次使用了表达“原因与结果”或“感谢/多亏”的短语，请在文中找出来并补全。 1. Thanks to... (多亏了/由于): · Thanks to this, scientists can learn about ____________ in a particular place. · Thanks to this ____________, archaeologists discovered a Viking village. 2. It means... (它意味着): · A black area usually means there was a ____________. 📝 第五步：归纳与应用 (Post-reading: Synthesis & Output) 探究任务： 假如你是一棵生长在校园里50年的老树。请仿照课文，写一段你的“记忆”。 Outline (写作提纲): · Who am I? (I am an old tree in...) · What do my rings say? (Find a year with lots of rain/sun or a very dry year.) · Conclusion: (Isn't it amazing that I can tell you my story?) My Tree Diary: ✅ 自我评价 (Self-check) · [ ] 我能说出年轮宽窄代表的不同气候含义。 · [ ] 我掌握了 thanks to 和 mean 在文中的用法。 · [ ] 我理解了科学家是如何利用年轮研究历史的。 写作范文：如何阅读树木的“记忆” (Model Essay) How to Read the Memories of Trees [WHAT] Tree rings are the circular patterns found inside a tree trunk after it is cut down. They are known as the "memories of trees" because they store many secrets from the forest's past. [WHY] These rings are very useful because they act as a record of the environment. By studying them, scientists can understand climate change, find out when natural disasters happened, and even learn about human history. [HOW] Here is how you can "read" these memories. First, count the number of rings to tell the age of the tree. Second, look at the width of each ring: a wide ring means the tree had enough sun and rain, while a narrow one shows a dry season. Finally, check for black areas; these scars usually tell us when a forest fire occurred. 学科网（北京）股份有限公司 $
