电子备课教案 课 题  B3U3 词汇与语法复习（太空探索主题） Review of vocabulary 教学课时 第 1 课时 教学目标 At the end of this class, students can 1. Master the word formation and key usage of core vocabulary such as explore, launch, and orbit, and understand sentence structures like the absolute construction and the "quantifier/noun + of + relative pronoun" attributive clause. 2. Apply the reviewed language knowledge to comprehend passages and produce sentences related to the theme of space exploration. 3. Enhance their ability to build vocabulary networks and summarize grammar through collaboration and independent inquiry, while fostering interest in space exploration and interdisciplinary thinking. 教学 重难点 1. Help students master the derivative relationships of key vocabulary and the composition and function of the two core sentence structures. 2. Guide the students to correctly and appropriately use the absolute construction and understand and apply the complex attributive clause to describe partial or possessive relationships of antecedents in their own output. 教学方法 Lecture method Situational teaching method 学情分析 Prior to this class, students have acquired basic principles of word formation. This lesson aims to leverage that knowledge by encouraging associative learning—linking familiar structures to new review content. The primary goal is to solidify students' grasp of fundamental expressions, which is crucial for practical application in writing. A parallel goal is to develop their contextual awareness, training them to mentally pair expressions with situations where they would be appropriately used. 教学过程 备注 Step 1: Self-directed Study (15 mins) Task 1: Word Formation by Group Work 学生分组讨论，完成下列核心词汇的构词法转换，并注意发音。 1. explore v. 探索 → exploration n. 探索 → explorer n. 探索者 2. launch v. 发射；发起 → launcher n. 发射器 → relaunch v. 重新发射 3. orbit n./v. 轨道；绕轨道运行 → orbital adj. 轨道的 → orbiter n. 轨道飞行器 4. sustain v. 维持；支撑 → sustainable adj. 可持续的 → sustained adj. 持续的 5. adapt v. 适应；调整 → adaptation n. 适应 → adaptable adj. 适应性强的 6. isolate v. 隔离；使孤立 → isolation n. 隔离 → isolated adj. 偏远的；孤立的 7. mission n. 任务；使命 → missionary n. 传教士 (词义拓展) 8. generate v. 产生；发电 → generation n. 产生；一代人 → generator n. 发电机 9. colony n. 殖民地；聚居地 → colonize v. 殖民 → colonist n. 殖民者 10. technology n. 技术 → technological adj. 技术的 → technologist n. 技术专家 11. exist v. 存在 → existence n. 存在 → existing adj. 现存的 12. hazard n. 危险 → hazardous adj. 危险的 13. simulate v. 模拟 → simulation n. 模拟 → simulator n. 模拟器 14. construct v. 建造 → construction n. 建造 → constructive adj. 建设性的 15. suit n. 套装；v. 适合 → suitable adj. 合适的 → spacesuit n. 宇航服 (合成词) 16. consume v. 消耗；消费 → consumption n. 消耗 → consumer n. 消费者 17. settle v. 定居；解决 → settlement n. 定居点；解决 → settler n. 定居者 18. contain v. 包含；容纳 → container n. 容器 → containment n. 控制；遏制 【设计意图】 通过小组合作自主学习，激活学生已有词汇知识，系统梳理与太空探索主题相关的词汇网络，掌握构词规律，为在复杂语境中准确运用打下坚实基础。 Task 2: Grammar Filling in Context 阅读下面关于火星任务的短文，在空格处填入一个适当的词或所给词的正确形式。 The dream of a human 1.________ (mission) to Mars has always been a major driver of space exploration.
