教学过程（40 分钟）
环节 时长 教学活动 师生行为 设计意图
Step 1 话题导入 + 情境创设 5min 1. 主题呈现：展示本课主题页（Unit 6 Beyond Earth / How far can we go into space / Section B (3a-3c writing)），呈现学习目标——Language Ability: Use the "dream + reasons" structure and space vocabulary to write about a space dream. / Thinking Quality: Analyze the writer's three reasons and evaluate the importance of space dreams. / Learning Ability: Extract the structure from a model text and apply it to independent writing. / Cultural Awareness: Understand that personal dreams connect to humanity's greater journey of exploration. 明确本课写作任务。
2. 图片导入：展示主题图（宇航员与空间站），提问：What can you see in the picture 引出 astronauts、space station，激活太空话题，自然引出“我的太空梦”写作主题。 教师展示主题页与学习目标，展示图片并提问；学生观察图片回答问题，了解本课写作任务，进入太空梦话题情境。 以主题图与四维目标导入，明确本课“用英语写太空梦”的写作任务，激活学生的太空背景知识与表达欲望。
Step 2 Task 3a 范文精读 + 结构拆解 10min 1. 初读定题：通读范文 My Space Dream，回答：What's the topic of today's writing （My dream for space）。
2. 结构三问：围绕范文提出三个问题——What is the dream / Why does he/she have this dream / What is his/her expectation 引导学生关注文章的整体结构。
3. 完成图表（3a）：完成结构图表——What （Para.1: One day a space station will be built on the moon.）；Reason 1（Para.2: a good place for scientists to cooperate and do space research）；Reason 2（Para.3: More resources will be found.）；Reason 3（Para.4: People may live and work there.）。 教师带领学生阅读范文，逐层提问并共同完成结构图表；学生阅读范文，提取梦想、三个理由与期望，归纳“梦想+理由”的段落结构。 以范文为写作支架，通过“三问+图表”帮助学生自主发现“dream + 3 reasons + expectation”的文章结构，为独立写作奠定框架基础。
Step 3 Task 3b 话题讨论 + 观点交流 8min 1. 观点讨论（3b）：呈现四个太空设想——build a space station on the moon / send a spacecraft to the nearest star / search for life in the solar system / build a satellite to collect the sun's energy and send it to Earth，讨论：Which interests you the most and why 结合各设想的具体理由进行交流（如月球空间站：do lots of special science experiments there that we cannot do on Earth / be a safe stopover for astronauts before they fly to other far planets / become a backup home for humans to live on）。
2. 梦想畅谈：As a teenager, what's your dream for space 学生初步口头表达自己的太空梦。 教师组织小组讨论，引导学生结合各设想的具体理由表达观点；学生讨论自己最感兴趣的太空设想及原因，并初步口头分享自己的太空梦。 通过 3b 的开放讨论积累写作素材与理由，实现从“读范文”到“说观点”的过渡，为 3c 独立写作做好内容储备。
Step 4 写作指导 + 3c 独立写作 12min 1. 理由展开技巧：分析 How did the writer explain his/her reasons 总结理由的展开方式——topic sentence（主题句）+ Add specific facts & future values（补充具体事实与未来价值）/ Explain real functions & connections（解释实际功能与联系）/ Describe vivid pictures with personal ideas（用个人想法描绘生动画面）。
2. 句型支架：学习实用句型——Not only can we... here, but the achievements will also help us... / We are able to..., and these results will make it possible for humans to... / Imagine that we can... in space. It is my biggest wish to experience this amazing life. / We can make full use of..., so people on Earth will no longer worry about the shortage of...
3. 结构与语法要点：明确 Structure（dream / 3 reasons / expectation）与 Tense & Person（Simple future tense & the first person）。
4. 独立写作（3c）：按要求 Write your own space dream. You can include some pictures in your writing. 学生运用“梦想+三个理由+期望”的结构完成太空梦短文初稿。 教师讲解理由展开技巧与句型支架，明确结构与语法要求，巡视指导学生写作；学生记录写作要点，运用所学结构独立完成太空梦短文初稿。 搭建“理由展开—句型—结构—语法”四重写作支架，帮助学生把讨论中积累的内容组织成文，在限定时间内写出结构清晰、表达准确的太空梦短文。
Step 5 互评展示 + 语言巩固 5min 1. 对照清单互评：呈现 Checklist（Clear structure, Topic sentence, More relative information, Right linking words, Right grammar, Right spelling, Good handwriting），按 Read and check, then exchange and check! 完成 Self-evaluation、Peer-evaluation 与 Teacher-evaluation。
2. 范文欣赏：展示范文（以建造太阳能卫星收集太阳能并送回地球为梦想的短文），分析其结构与亮点。
3. 当堂检测：完成单词默写（resource, operate, cooperate, explore, energy, tourist, lifetime, achieve）、词组默写（space dream, space station, do research, energy resources, in the near future, spend holidays, explore the universe, set foot on the moon for the first time, during one's lifetime, live there）与汉语提示填空（be built, quite a few, cooperate, developed, operated, build, resources, found, energy resources, live, work, Tourists, achieved, dreams），并核对答案。 教师组织自评互评与范文展示，随堂检测核心词汇与短语；学生交换作文按清单互评，欣赏范文，完成检测练习并订正。 即写即评、即练即巩固，评价清单为学生提供明确的修改方向；通过三类检测练习夯实写作所需的语言基础。

课后教学反思
反思板块 记录要点
词汇难点 学生能否准确掌握 resource, operate, cooperate, explore, energy, tourist, lifetime, achieve 等核心词汇的拼写与用法？写作中能否正确使用 space dream, in the near future, explore the universe, set foot on the moon 等短语？
结构/逻辑难点 学生在完成 3a 图表时，能否顺利理清范文“dream + 3 reasons + expectation”的结构？在 3c 独立写作中，能否用 First / Second / Third 等衔接词组织三个理由，保持段落间的顺畅过渡？
时态人称运用 学生在写作中能否统一使用一般将来时与第一人称（will be built, will be found, I hope...）？是否会出现时态混用或人称混乱的情况？
思辨与升华 通过讨论太空设想与自己的太空梦，学生是否领悟到“个人梦想与人类探索之旅紧密相连”？能否在结尾的期望部分写出自己真实的梦想与展望？
