Unit 6 Beyond Earth Section B (1a-1e) 教案 一、课题 Unit 6 Beyond Earth — Section B (1a-1e) Reaching For the Stars 教材分析 本课为人教版（2024）九年级上册Unit 6 Section B的1a-1e部分，围绕“太空探索”主题展开。课文“Reaching For the Stars”介绍了人类探索星空的历史、旅行者1号（Voyager 1）的成就、载人星际旅行面临的挑战以及未来实现星际旅行的可能性。1a激活学生关于太空探索信息来源的已有认知；1b通过略读和寻读训练学生的阅读理解能力；1c要求学生匹配段落大意，培养概括能力；1d以思维导图形式梳理文本信息；1e通过讨论问题培养学生的批判性思维与口语表达能力。本课在语言知识层面涵盖10个新词（god, mysterious, spacecraft, board, billion, trillion, cooperate, galaxy, imagination, expectation）、4个核心短语（in case, on board, cooperate with, set foot on）及2个语言点（in case和cooperate with），为后续写作和口语输出奠定基础。 学情分析 九年级学生对太空探索话题有较强兴趣，但相关词汇储备有限，对billion、trillion等大数表达和light years等天文概念较陌生。学生已具备一定的阅读策略基础，但在快速获取段落大意和构建思维导图方面仍需指导。 二、核心素养目标 1. 语言能力：掌握10个新词及4个核心短语的用法，能运用in case和cooperate with进行造句和翻译；理解并复述课文主要内容。 2. 思维品质：通过段落匹配和思维导图，培养信息概括与逻辑梳理能力；通过1e讨论，发展批判性思维。 3. 文化意识：了解人类太空探索的成就与挑战，培养科学探索精神与国际合作意识。 4. 学习能力：运用略读、寻读等阅读策略，提升自主阅读与合作学习能力。 三、教学重难点 重点：10个新词的音形义；in case和cooperate with的用法；课文内容的理解与复述。 难点：in case引导的目的状语从句中时态的运用；运用课文信息完成思维导图并展开口语讨论。 四、教学过程 （一）情景导入 【教师活动】展示宇宙星空图片或短视频，提问：“How far can we go into space?” 引导学生思考人类探索太空的历程与可能性，激活学生已有知识背景。 【学生活动】观察图片或视频，自由讨论对太空探索的了解与兴趣，分享自己所知道的太空知识。 【过渡语】同学们对太空探索充满了好奇和想象，要深入了解这个话题，我们需要先掌握一些相关的新词汇。 （二）新知呈现 1. 词汇学习（第一组） 【教师活动】呈现并领读第一组新词：god /gɒd/ n. 神；mysterious /mɪˈstɪəriəs/ adj. 神秘的；奇怪的；spacecraft /ˈspeɪskræft/ n.

Where would you find an article like this?” 呈现文章标题“Reaching For the Stars”及全文，引导学生快速浏览判断文章出处。 课文全文如下： Reaching For the Stars Since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believed that these points of light were from gods or other mysterious worlds. However, as technology and science developed, we learnt the truth about stars. They are real places like our own sun, and they are farther away than anyone imagined. This raises the question: Can we visit the stars one day? The man-made object which has travelled farthest from Earth is Voyager 1. This spacecraft was launched in 1977. In case Voyager 1 is found by alien life, a special record with sounds and pictures from Earth is carried on board. It shows who we are and where we are from. By 2025, Voyager 1 was over 25 billion kilometres from Earth, but that is still a long way from Earth's second-closest star, Proxima Centauri. That star is 4.2 light years away—about 40 trillion kilometres! The challenge of visiting the stars gets even bigger for space flights with humans. The farthest that any human has travelled in space is only about 400,000 kilometres, to the far side of the moon. Time is a big problem. At present, even a journey to the planet Mars will take around six to nine months. What will the astronauts eat and drink during this period? And how about their health and safety? These problems grow when we talk about visiting another star. It might take hundreds of thousands of years to get there! Scientists, however, believe that visiting the stars is not a completely wild dream. One idea is to have the astronauts sleep during their journey, like some animals do in winter. Another is to develop much faster spacecraft. While this is not possible right now, with nations and scientists cooperating with one another, there is hope that the necessary technology will be developed. Humans have photographed other galaxies, set foot on the moon, and even successfully landed rovers on Mars. It seems likely that one day we will reach the stars. 1b 阅读课文 Reaching For the Stars（标题及第一段） 【学生活动】快速阅读标题和全文，判断文章出处（科普杂志），圈画关键词和每段主题句。 【教师活动】引导学生逐段阅读课文，理解每段主要内容：第一段讲人类对星辰的好奇与认知发展；第二段介绍旅行者1号的发射及成就；第三段分析载人星际旅行面临的挑战；第四段展望未来实现星际旅行的可能性。 【学生活动】逐段细读课文，标注每段关键信息，理解文章脉络，尝试用自己的话概括每段大意。 【过渡语】通过阅读我们了解了课文的主要内容，接下来通过段落匹配来梳理文章结构。 （三）知识操练 1. 1c 段落大意匹配 【教师活动】呈现1c任务：“Read again and match each paragraph with its main idea.” 引导学生再读课文，将段落与主旨大意匹配。匹配结果如下： Paragraph 1 — B. Humans have long been curious about the stars. Paragraph 2 — D. No spacecraft has travelled close to a star. Paragraph 3 — A. Long distance space travel is difficult for humans. Paragraph 4 — C. In the future, it may be possible to visit a star. 1c 段落大意匹配 【学生活动】再读课文，匹配段落大意，说明判断依据，核对答案。 【过渡语】我们已经把握了文章的结构，现在来学习课文中出现的一个重要语言点——in case的用法。 2. 语言点1：in case 【教师活动】讲解语言点in case的用法： （1）in case意为“以防；万一；免得”，引导目的状语从句，表示提前做准备，预防将来可能发生的事。 （2）易混辨析：in case + 从句 = 以防万一；in case of + 名词/代词 = 万一；倘若（后不接句子）；in no case = 绝不（句首倒装）；as is often the case = 情况往往如此。 （3）in case从句常用一般现在时表将来。主句为将来时或祈使句时，从句不用will，用一般现在时。例：Take an umbrella in case it rains.（带把伞，以防下雨。） 语言点1 in case用法讲解 【知识点】in case引导目的状语从句的用法：从句用一般现在时表将来，主句为将来时或祈使句时从句不使用will。 【提示框】in case of后接名词或代词，不接句子；in no case置于句首时，主句需部分倒装，如：In no case should you give up.（你绝不应该放弃。） 【学生活动】做笔记，理解in case的用法和易混辨析，完成课堂练习。 【过渡语】掌握了in case的用法后，我们用思维导图来梳理课文信息。 3. 1d 思维导图 【教师活动】呈现1d任务：“Complete the mind map with the information from the text. You can use your own words.” 引导学生根据课文内容填写思维导图。第一部分（Human Imagination和Achievement）： Human Imagination: ① Humans looked up at the stars and wondered what they were like. ② People learnt the truth about stars as technology and science developed. Achievement: ① Voyager 1 was launched in 1977. ② Voyager 1 carried a special record. 1d 思维导图（第一部分） 【学生活动】回顾课文内容，完成思维导图Human Imagination和Achievement部分，核对答案。 【教师活动】引导学生完成思维导图第二部分（Challenge和Expectation）： Challenge: ① Even a journey to the planet Mars will take around six to nine months. ② Astronauts may face health and safety problems. Expectation: ① Astronauts can sleep during their journey. ② We can develop much faster spacecraft. 1d 思维导图（第二部分） 【学生活动】完成思维导图Challenge和Expectation部分，核对答案，理解课文信息的逻辑结构。 （四）知识拓展 1. 1e 讨论问题 【教师活动】呈现1e任务：“Discuss the questions. Find more information to support your answers.” 引导学生讨论前两个问题： Q1: What did some ancient cultures think about the stars? Why? 参考答案：Some ancient cultures thought the stars were lights from gods or mysterious worlds, because they had no advanced technology to study stars scientifically. Q2: What is carried on board by Voyager 1? Why? 参考答案：Voyager 1 carries a special record with Earth's sounds and pictures. It is for alien life to learn about humans if they find the spacecraft. 1e 讨论问题（1-2） 【学生活动】小组讨论问题1和问题2，结合课文内容作答，派代表汇报讨论结果。 【教师活动】引导学生讨论后两个问题： Q3: What is the farthest trip that a human has travelled from Earth? 参考答案：The farthest human trip from Earth is about 400,000 kilometres, to the far side of the moon (from the Apollo missions). Q4: What do you think about the future of space exploration? 参考答案：The future of space exploration is promising. With technological progress and international cooperation, we may solve problems like long travel time and health risks, and one day reach other stars. 1e 讨论问题（3-4） 【学生活动】小组讨论问题3和问题4，结合课文内容和个人知识作答，派代表汇报讨论结果。 【过渡语】讨论之后，我们来学习课文中另一个重要语言点——cooperate with的用法。 2. 语言点2：cooperate with 【教师活动】讲解语言点cooperate with的用法： （1）cooperate with意为“合作；协作；配合”。 （2）固定搭配：cooperate with sb. 与某人合作/配合某人。例：We should cooperate with our classmates.（我们应该和同学合作。） （3）同义替换：work with sb. / team up with sb. / make joint efforts with sb. 语言点2 cooperate with用法讲解 【知识点】cooperate with的固定搭配cooperate with sb.，以及同义替换work with sb.、team up with sb.、make joint efforts with sb.。 【提示框】cooperate为不及物动词，后接合作对象需用介词with；其名词形式为cooperation，形容词形式为cooperative。 【学生活动】做笔记，理解cooperate with的用法，完成课堂练习。 五、板书设计 Unit 6 Beyond Earth Section B (1a-1e) Reaching For the Stars New Words: Expressions: Language Points: god in case 1. in case + 从句 (一般现在时表将来) mysterious on board in case of + n. spacecraft cooperate with in no case (句首倒装) board set foot on 2. cooperate with sb. billion = work / team up with sb. trillion cooperate galaxy imagination expectation 学科网（北京）股份有限公司 $
