Unit 6 Beyond Earth Section A 2a-2e 教学设计 2026-2027学年人教版九年级英语上册 一、教材分析 本课是人教版九年级英语上册Unit 6 Beyond Earth的Section A部分第二课时，主要内容围绕听力训练和口语交际展开，语篇素材聚焦太空探索这一主题。2a环节要求学生通过阅读句子内容，对听力材料中人物的观点进行预判；2b环节要求学生听录音，判断句子描述的观点分别属于哪个人物；2c环节要求学生听录音完成信息表，梳理不同人物对太空探索的具体看法和理由；2d环节为角色扮演对话，要求学生模仿听力素材中人物的讨论方式，就太空探索话题发表自己的观点并回应他人；2e环节为小组口语活动，引导学生围绕太空探索的相关话题展开交流讨论。 从单元整体来看，本单元以太空探索为主线，Section A部分侧重听说能力的培养，引导学生运用宾语从句、被动语态等语法结构表达对太空探索的观点和态度。本课时上承2a-2e中的听力策略训练，下启Section A后面的语法聚焦和Section B的读写任务，在整个单元中起到承上启下的作用。本课时的核心价值在于帮助学生积累与太空探索话题相关的词汇和表达方式，训练学生听取观点性信息和细节信息的能力，并在此基础上引导学生进行观点表达和交际互动，为后续更深入的读写任务做好语言和思维上的铺垫。 二、学情分析 九年级学生经过两年多的英语学习，已经掌握了基本的听力技巧，能够听懂语速适中的对话材料，具备了一定的信息获取和处理能力。在语言积累方面，学生已经学习过宾语从句的基本用法，能够运用I think that...、I believe...等句型表达个人观点，也积累了一些与科技、环境等话题相关的词汇。在话题认知层面，学生对太空探索这一主题并不陌生，在八年级接触过相关阅读材料，同时在日常生活和科普读物中对航天员、探测器、太空站等概念有所了解。 但是，学生在学习本课时仍然面临几个困难。第一，听力材料中涉及的观点表达较为丰富，部分学生难以在听录音的过程中同时完成对人物身份的判断和观点理由的提取，信息的同步处理能力有待加强。第二，学生对部分词汇如space exploration、astronaut、robot、planet等掌握程度参差不齐，部分基础薄弱的学生在完成听力任务时可能因为词汇障碍而影响理解。第三，在口语输出环节，部分学生习惯于简单回答，难以运用完整的语句结构和丰富的表达方式阐述自己的观点，需要进行针对性的语言支撑和表达示范。 三、教学目标 1.语言能力目标： 学生能够听懂有关太空探索话题的对话，获取对话中人物对太空探索的不同观点及其理由；能够运用I think...、I believe...、In my opinion...等句式表达自己对太空探索的态度和看法；能够正确使用because、so that等连词说明理由，使表达具有逻辑性。 2.文化意识目标： 学生能够了解不同国家在太空探索领域的努力和成就，认识到太空探索对人类社会发展的重要意义，增强对航天事业的关注和兴趣，培养探索未知、勇于创新的精神。 3.思维品质目标： 学生能够通过听前预判、听中验证、听后反思的听力训练过程，发展推理判断能力和信息整合能力；能够对太空探索的利弊进行辩证思考，形成有理有据的个人判断。 4.学习能力目标： 学生能够掌握利用关键词和信号词捕捉听力信息的策略，学会在听录音前主动预判内容，在听录音过程中有目的地获取信息，在听后利用已有信息进行自我检测和修正。 四、教学重点和难点 1.教学重点： 听懂有关太空探索的对话内容，准确获取人物观点和理由的细节信息；运用恰当的语言结构和表达方式就太空探索话题发表个人观点。 2.教学难点： 在听力过程中同时关注人物身份、观点内容和理由信息，实现多维度信息的同时捕捉和整合；在口语表达中能够运用多样化的句式结构阐述观点，使表达内容丰富、逻辑清晰。 五、教法与学法 1.教法： 任务型教学法、情境教学法。通过设置听前预测、听中记录、听后复用的阶梯式任务链，帮助学生在真实语境中习得语言知识和交际技能。教师采用逐步引导、层层追问的方式，启发学生主动思考，在师生互动中完成语言输入到语言输出的转化。 2.学法： 自主学习与合作学习相结合。学生在听前自主阅读句子并进行预判，在听中独立完成信息记录，在听后通过同伴交流和小组讨论进行语言输出，在互动中学习他人的表达方式，反思和调整自己的听力和口语策略。 六、教学过程 （一）课堂导入（5分钟） 教师活动： 上课伊始，教师用轻松的口吻和学生们打招呼:"Good morning, class! Today we are going to talk about a very exciting topic. Before we start, let me ask you a question. Have you ever watched any news about space exploration on TV? What did you see?" 教师停顿，示意学生举手回答。随后教师继续引导:"Last month, our country's Shenzhou spacecraft completed another successful mission. Can you tell me what you know about it? What do astronauts do in space?" 在学生发表看法之后，教师进一步创设情境： "Imagine you are standing on the Earth and looking up at the starry sky at night. Do you ever wonder what is out there beyond our planet? Is there life on other planets? Do you think it is important for humans to explore space? Today, we are going to listen to a conversation between Mark and Emma. They have different ideas about space exploration. Let's find out what they think." 教师板书课题： Unit 6 Beyond Earth Section A 2a-2e，并写出核心问题:Why do some people support space exploration? Why do some people disagree? 学生活动： 学生积极回忆自己了解的太空探索新闻和知识，举手回答问题。有的学生回答:"I saw the Shenzhou spacecraft launch on TV. The astronauts stayed in the space station for six months." 有的学生回答:"I know that astronauts do experiments in space and they also do spacewalks." 还有学生回答:"I think space exploration is very cool because we can learn about other planets." 可能出现的不准确回答为:"I don't know anything about space exploration." 或 "Space exploration is a waste of money." 教师对学生的回答给予肯定和引导:"Good point! Thank you for sharing. That's an interesting idea. Let's keep it in mind and see what others think about it." 设计意图： 通过自由交谈激活学生已有的背景知识和相关词汇储备，将学生的注意力从课间状态自然过渡到本课话题上来。以神舟飞船等学生熟悉的航天事件为切入点，能够有效拉近话题与学生的距离，使学生在心理上产生亲近感和表达欲望。引导学生就太空探索的价值发表初步看法，为后续听力材料中观点的理解和比较做好认知铺垫。 （二）听前预测，激活思维（5分钟） 教师活动： 教师引导学生翻开教材，阅读Section A 2a部分的五个句子。教师发出明确指令:"Now please read the five sentences in activity 2a by yourself. While you are reading, think about one question: Who might say each sentence, Mark or Emma? Do not look for the correct answer yet. Just make a guess based on your common sense. If you think the sentence shows a positive attitude towards space exploration, you can guess it is from Mark. If you think it shows a negative attitude, you can guess it is from Emma. Work individually for two minutes." 在充分阅读时间后，教师组织学生进行同伴交流:"Now turn to your partner and share your guesses. Tell your partner why you made this guess. For example, if you think sentence one is from Emma, you can say: I think Emma would say this because she may think space exploration costs too much money." 随后，教师邀请几组学生汇报猜测结果和理由。教师追问:"Which sentences were easy to judge? Which sentences were difficult? Why do you think some sentences are difficult to judge?" 学生活动： 学生独立阅读五个句子，根据句子内容和个人常识进行初步判断，在句子旁边标注Mark或Emma。同伴交流时，学生相互分享自己的判断并说明理由。学生可能给出的回答示例: 正确回答示例一： "I think sentence 'We should spend more money on space exploration' is from Mark. Because Mark probably supports space exploration, so he would say we should spend more money on it." 正确回答示例二： "I think the sentence that says space exploration helps us learn about the universe is from Mark, because people who support space exploration often use this as a reason." 正确回答示例三： "I think the sentence about robots can do dangerous work in space is from someone who still supports space exploration but thinks robots are better than humans. It is difficult to judge because both Mark and Emma might say it." 典型错误回答示例一： "I think all the sentences are from Mark because this unit is about space and Mark is the main speaker." 教师应引导:"That might not be true. In real conversations, people often have different opinions. Let's listen carefully to find out who says what." 典型错误回答示例二： "I don't know which sentence is from whom. It's too hard to guess." 教师应鼓励:"That's okay. Guessing is just a warm-up. You don't need to get the right answer now. The important thing is that you are thinking. After we listen, we will check your guesses." 设计意图： 听前预测是听力策略训练的重要环节，能够激活学生的背景知识，帮助学生建立对听力内容的心理预期。本环节要求学生将五个句子与人物观点进行初步匹配，目的是让学生提前接触听力材料中的关键信息，降低后续听力理解的难度。通过同伴交流和分享猜测理由，学生需要在口头上说明自己的判断依据，这实际上是在为后续的听力验证做好语言和思维的双重准备。教师在此环节不追求答案的正确性，而是重点关注学生的思考过程和表达欲望。 （三）听力理解，信息获取（12分钟） 1.第一遍听力（5分钟） 教师活动： 教师播放录音，要求学生完成2b任务。播放前，教师给出明确指导:"Now we are going to listen to the conversation between Mark and Emma. Please listen carefully and find out which person said each sentence in 2a. Write M for Mark and E for Emma next to each sentence. Remember, you don't need to understand every word. Just focus on who said each sentence. Are you ready? Let's listen." 第一遍录音播放结束后，教师不立即公布答案，而是让学生先与同伴核对答案。教师巡视课堂，关注学生的完成情况。随后教师请学生逐句汇报答案，并在黑板上的板书区域记录学生给出的答案。教师针对存在争议的句子进行追问:"Sentence two has different answers from different groups. Some of you think it is from Mark, and some think it is from Emma. Why do you think so? Let's look at the exact words again." 2.第二遍听力（4分钟） 教师活动： 教师播放第二遍录音，要求学生完成2c的信息表填写。播放前，教师给出指导:"This time, listen more carefully. I want you to complete the chart in activity 2c. You need to write down what Mark and Emma think about space exploration and the reasons they give. Pay attention to the key words and phrases. For example, if Mark says space exploration is worth it, you can write 'worth it' in the chart. If Emma says it costs too much money, you can write 'costs too much'." 录音播放结束后，教师请几名学生分享他们填写的信息表，其他学生进行补充和修正。教师在黑板上逐步完成信息表的板书，一边写一边用语言描述:"Mark thinks space exploration is important because it helps us learn about the universe and it can also help us find new resources on other planets. Emma thinks space exploration costs too much money and we should spend the money on solving problems on Earth like poverty and pollution." 3.核对与反馈（3分钟） 教师活动： 教师组织全班核对2b和2c的答案。教师逐一说出每个句子的编号和对应的人物，学生对照自己的答案进行自我检查和修正。教师特别强调:"If you got some wrong answers, don't worry. That's a normal part of learning. The important thing is that you understand why the correct answers are correct." 随后教师引导学生思考： "Now let's think about this question. Mark and Emma have different opinions about space exploration. Who do you agree with? Why?" 教师请两三位学生表达看法，并追问理由:"That's an interesting opinion. Can you tell me more about why you think so? What evidence do you have to support your idea?" 学生活动： 学生认真听录音，根据录音内容在2a的句子上标注M或E，在2c的信息表中填写人物观点和理由。第一遍听音时，部分学生可能只能捕捉到部分信息，互相核对时可以借助同伴的信息补充自己的不足。第二遍听音时，学生针对信息表中的空缺项目进行有目的的听取。 学生完成的2b答案示例: 第一句是Emma说的。第二句和第三句是Mark说的。第四句是Emma说的。第五句是Mark说的。 学生填写2c信息表的回答示例: 正确回答示例一： "Emma thinks space exploration is too expensive and she thinks the money should be used to help poor people on Earth." 正确回答示例二： "Mark thinks sending robots to space is better than sending humans because robots do not need food or water and they can do dangerous work." 典型错误回答示例一： "Mark thinks we should not spend money on space exploration." 教师应及时纠正:"Wait, let's check that again. Did Mark say that, or was it Emma? Let's listen to that part once more.") 典型错误回答示例二： "Emma thinks robots are better than humans for space exploration." 教师引导:"Actually, that was Mark's idea. Emma said robots are useful, but she still thinks the money problem is more important. Let 's look at the exact words in the chart.") 设计意图： 听力训练的核心理念是由浅入深、循序渐进。第一遍听力聚焦人物与观点的对应关系，训练学生的泛听和匹配能力，难度较低，能够帮助大部分学生建立信心。第二遍听力聚焦观点和理由的细节信息，训练学生精听和记录能力，难度有所提升，需要学生运用关键词捕捉策略。两个听力任务内部构成从整体到细节的阶梯关系，学生在完成第二个任务时可以借助第一个任务的信息来验证自己的判断，这种任务之间的关联性符合学生认知加工的特点。在核对答案的环节中，教师既不简单公布答案，也不放任学生困惑，而是通过追问和讲评帮助学生理解正确与错误背后的原因，实现听力策略的可迁移。 （四）角色扮演，内化语言（7分钟） 教师活动： 教师带领学生进行2d的角色扮演活动。首先，教师播放2d对话录音，让学生整体感知对话内容。随后，教师领读对话，逐句注意语音语调的示范:"Please pay attention to the intonation. When Mark says 'I think space exploration is important for our future,' his voice goes up slightly at the end because he is expressing his strong belief. When Emma says 'Maybe you are right, but...' her voice goes down and then pauses, because she is showing that she is thinking." 教师将学生分成两人一组，一人扮演Mark，一人扮演Emma，要求学生模仿录音中的语音语调和情感态度进行对话练习。教师提醒学生:"Remember to use your voice to show your feelings. Mark is excited and confident about space exploration. Emma is careful and a little worried about money." 练习结束后，教师邀请两组学生在全班面前表演对话。表演结束后，教师进行简单评价:"Your pronunciation is very good. I especially like the way you showed Emma's tone of hesitation. That's exactly how she feels in the conversation." 随后，教师引导学生在原对话基础上进行替换练习:"Now let's make our own conversation. You can keep the same structure but change the content. For example, instead of talking about money, you can talk about other reasons why some people do not support space exploration, such as the risk to astronauts' lives. Work with your partner and create a new conversation." 教师提供语言支架，并在黑板上板书核心句型: I think that... because... I believe... In my opinion... From my point of view... I agree with you, but... That's a good point. However... 学生活动： 学生跟随教师朗读对话，注意模仿语音语调。结对练习时，学生积极调整自己的语气和表情，努力体现人物性格特征。在替换练习环节，学生尝试运用新的观点和理由创编对话。 学生表演对话的示例: 正确回答示例一: Mark： I believe space exploration is important for our future. It helps us understand our planet and the universe better. Emma： That's a good point. However, I still think the money could be better spent on helping people on Earth. 正确回答示例二: Mark： In my opinion, we should send more robots to explore space because they don't need food or water. Emma： I agree that robots are useful. But building and sending rockets still costs a lot of money, doesn't it? 典型错误回答示例一： "I think space exploration is very good. But I think robots are bad." 教师在反馈时提示:"You have given an opinion, but you haven't explained the reason. Can you add a because clause to support your point?") 典型错误回答示例二： "Mark is saying that we should spend money on space. Emma is saying that we should not spend money. They are fighting each other." 教师引导:"They are not fighting; they are discussing. They listen to each other and give reasons. Let's try to do the same in our conversation.") 设计意图： 角色扮演是语言输入向语言输出转化的关键桥梁。在本环节中，学生先通过跟读模仿熟悉对话的语言结构和语音语调，再通过集体练习内化语言形式，最后通过替换练习实现语言的创造性运用。这种从模仿到创造的活动链条符合语言学习的基本规律，让学生在真实交际情境中运用所学语言进行有意义的表达。教师提供语言支架的方式既避免了学生因语言困难而无话可说，又给学生保留了充分的自主创造空间。邀请部分小组进行表演展示，既是对学习成果的检验，也是为其他学生提供学习的范例。 （五）小组讨论，观点表达（6分钟） 教师活动： 教师将学生分成四人小组，布置2e的讨论任务。教师提出讨论话题:"Now it's your turn to have a discussion about space exploration. Here are some questions for you to discuss in your group. First, do you think space exploration is worth the money? Why or why not? Second, would you like to be an astronaut if you had the chance? Why or why not? Third, do you think humans will live on other planets in the future?" 教师明确讨论规则： "Each group member should share at least one idea. When one person is talking, the others should listen carefully. After the speaker finishes, you can ask questions or add your own opinions. Try to use the sentence patterns we learned today." 在学生讨论过程中，教师巡回各小组，倾听学生的讨论内容，在学生表达困难时给予及时帮助，在学生表达有误时给予温和纠正。教师提醒学生:"If you agree with your classmate, you can say 'I agree with you. I also think...' If you disagree, you can say 'I see your point, but I think...' This will make your conversation more natural." 小组讨论结束后，教师邀请三个小组的代表汇报本组的讨论结果。教师引导代表用完整的句子进行汇报:"Our group thinks that... because..." 教师在每位代表发言后进行简要点评和追问。 学生活动： 学生在小组内围绕三个话题进行讨论，有学生提到人类探索太空的重要性，有学生质疑太空探索的巨额花费，有学生畅想未来在火星上生活的场景。小组成员相互补充、相互质疑，在交流中不断完善自己的观点和理由。 学生讨论中的回答示例: 正确回答示例一： "I think space exploration is worth the money because it helps us find new resources for the future. If we use up all the resources on Earth, we might need to find new ones on other planets." 正确回答示例二： "I would like to be an astronaut because I want to see the Earth from space. I think it must be a very beautiful view. But I am also a little afraid because it is dangerous." 正确回答示例三： "I think humans will live on other planets in the future, but it will take a long time. We need to solve many problems first, like how to grow food and how to get enough air." 典型错误回答示例一： "Space exploration is bad because it wastes time. We should not explore space at all." 教师引导:"Your opinion is very direct. Can you think of a more balanced way to express it? Maybe you can say 'I think space exploration is not the most urgent thing right now because...' This sounds more reasonable.") 典型错误回答示例二： "I don't know. I don't have any ideas about this topic." 教师鼓励:"It's okay if you don't have a full idea yet. You can use one of the reasons from the listening passage. For example, you can say 'I agree with Mark because...' or 'I agree with Emma because...' You don't have to create a completely new idea.") 设计意图： 小组讨论环节将课堂推向语言输出的高潮。本环节讨论的三个话题从对太空探索的总体评价，到个体参与太空探索的意愿，再到对太空探索未来发展的预测，三个问题形成从宏观到微观、从现实到未来的逻辑递进，引导学生从多角度、多层面思考和表达。小组讨论的形式能够降低学生当众发言的心理压力，让每个学生都有开口说英语的机会。在讨论过程中，学生需要综合运用本课所学的词汇和句型，将听力输入阶段获得的信息和语言进行创造性输出，实现语言知识的活学活用。 （六）分层巩固与课堂练习（3分钟） 教师活动： 教师设计两个层次的课堂练习，检验学生的学习效果。 基础巩固题： 教师口头说出一个观点句，要求学生快速判断这个观点更可能是Mark的还是Emma的。教师依次说出以下句子:"Sending humans to space is too dangerous. - Emma would say this." "Space exploration helps us find new things about the universe. - Mark would say this." "The money for space exploration should be used to help people in need. - Emma would say this." 能力提升题： 教师让学生在练习本上完成两个完成句子的任务。第一个句子为:In my opinion, space exploration is ** because ****. 第二个句子为:I think robots are better than humans for space exploration because **. 教师请两三位学生朗读自己写的句子，给出即时反馈。 学生活动： 学生在口头作答环节快速反应，集体或个别说出答案。在书面完成句子环节，学生独立在练习本上写出完整句子，然后积极举手朗读自己的句子。 学生作答的答案示例: 基础巩固题正确回答示例： "The first one is from Emma. Because she thinks space exploration is dangerous, so she doesn't like it." 基础巩固题典型错误回答示例： "The first one is from Mark. Because Mark is the boy and boys like dangerous things." 教师纠正:"That's not a good reason. We should not guess based on gender. We should listen to what the speakers actually say in the conversation. Mark actually thinks space exploration is important, so he would not say it is too dangerous. He does say it is dangerous for humans, but that is why he prefers robots." 提升题正确回答示例一： "In my opinion, space exploration is necessary because it helps us learn about the universe and maybe find a new home for humans in the future." 提升题正确回答示例二： "I think robots are better than humans for space exploration because robots do not need to eat or drink, and they can work in very dangerous places." 提升题典型错误回答示例： "I think robots are better than humans because robots are stronger." 教师引导:"That is true, but can you be more specific? What makes robots stronger? In the listening passage, Mark mentioned that robots don't need food or water. Can you add this idea to your sentence?") 设计意图： 课堂练习环节是教学反馈的重要手段。基础知识判断题帮助学生再次巩固听力内容中的人物观点对应关系，这一任务难度较低，面向全体学生，确保基础薄弱的学生也能参与并获得成就感。完成句子的任务则要求学生进行半开放性的语言产出，既限定了句型结构和话题方向，又允许学生根据自己的理解和语言水平进行个性化表达。通过即时反馈和针对性纠错，教师能够及时发现学生的理解偏差和语言错误，并给予有效的引导和纠正。 （七）课堂小结（3分钟） 教师活动： 教师引导学生回顾本课所学内容。教师提问:"What did we learn today? What new words and expressions did you learn? What did you learn about Mark and Emma's opinions on space exploration?" 教师在学生发言的基础上进行总结归纳，并在板书上将本课核心内容进行串联:"Today we listened to a conversation about space exploration. Mark supports space exploration because he thinks it can help us learn about the universe and find new resources. Emma thinks space exploration costs too much money and we should spend the money on solving Earth's problems. We also learned how to express our own opinions using I think, I believe, and In my opinion. Remember, when you express an opinion, you should always give a reason to support it." 最后，教师进行情感升华： "Space is vast and full of mysteries. Human beings have always been curious about the unknown. This curiosity drives us to explore, to discover, and to grow. Whether you agree with Mark or Emma, it is important to think independently and support your ideas with reasons." 学生活动： 学生主动回顾本课所学内容，回答教师的提问。学生回答示例:"I learned how to say my opinion in English. I can say I think space exploration is good because we can learn new things." 还有学生回答:"I learned that Mark likes space exploration and Emma worries about the money." 在教师的引导下，学生逐步形成对本课核心内容的整体认识。 设计意图： 课堂小结环节帮助学生理顺知识结构，将分散的学习内容整合为系统化的认知。通过学生自主回顾和教师归纳总结的双向互动，强化本课的核心知识点和关键技能，帮助学生形成清晰的学习脉络。情感升华部分引导学生从太空探索的话题中思考人类好奇心和探索精神的价值，实现语言学习与价值引领的自然融合。 （八）分层作业布置（2分钟） 教师活动： 教师布置三项分层作业，供学生根据自身情况选择完成。 基础作业（必做）： 模仿2d对话的结构，编写一段新的对话，对话中两人分别对太空探索持有支持和反对的态度，每人至少说出两个观点和两个理由。要求正确使用I think、I believe等表达观点的句型，不少于八句话。 提升作业（选做）： 写一段约八十词的短文，阐述你对太空探索的看法。短文需要包含明确的观点句、至少两个理由，以及一个总结句。可参考课堂讨论中同学们提到的观点。 拓展作业（挑战）： 假如你有机会与一位航天员进行一次五分钟的对话，你会问哪些问题？请写出五个问题，并预测航天员会如何回答其中两个问题。每个预测回答不少于两句话。 教师说明要求： "All of you should finish the first task. If you want more challenges, you can also do the second and third tasks. Please bring your work to our next class. We will share some of the best work." 学生活动： 学生认真记录作业要求，明确各项作业的具体内容。有学生举手询问:"Can I write about a different topic instead of space exploration?" 教师回答:"The topic should stay the same, but you can choose your own opinions and reasons. That way, every one of you will have a different dialogue or passage." 设计意图： 分层作业设计体现因材施教的教学原则。基础作业面向全体学生，以模仿创编的形式巩固课内所学，人人均可完成。提升作业面向学有余力的学生，通过短文写作锻炼学生在段落层面组织观点和理由的能力。拓展作业面向有浓厚兴趣和较高语言水平的学生，通过设计问题和预测回答的方式培养学生的创新思维和深层思考能力。三个层次的作业形成从基础到进阶再到挑战的梯度，满足不同学生的个性化发展需求。 七、课堂生成预设 1.学生在听前预测环节可能将句子的归属判断反。例如，学生可能认为"Space exploration is very expensive"这句话是Mark说的，因为Mark在讨论中提到花钱。实际上，在听力材料中，这句话是Emma用来反对太空探索的理由。教师应对策略:在学生完成预测后，不急于否定，而是引导学生在听录音时特别注意这句话是谁说出的，并追问:"Was your guess correct? Why or why not? What words in the sentence helped you determine the speaker?" 通过反思帮助学生理解人物的立场会直接影响其使用的语言表达。 2.学生在完成2c信息表时，可能将Mark和Emma的观点混淆，尤其是在两人观点出现的顺序和信息密度较高的情况下。教师应对策略:针对学生的错误匹配情况，在核对答案时重点分析两人的核心分歧点。教师可以让学生比较"Mark thinks space exploration helps find new resources"和"Emma thinks the money should be used to help poor people"两个句子之间的对比关系，帮助学生理清人物各自关注的核心问题。 3.学生在口语表达环节可能出现信息不完整、理由不充分的情况，表达时只给出观点而不能说明原因。例如学生说"I think space exploration is good"后，无法继续补充理由。教师应对策略:教师以追问方式引导:"Why do you think it's good? Can you give me an example? What can we learn from space exploration?" 同时，教师可以引导学生回顾听力材料中Mark和Emma陈述理由的方式，鼓励学生借鉴和重组这些理由来支撑自己的观点。 4.学生在小组讨论中可能出现一边倒的情况，所有学生都支持太空探索，缺乏反对意见的碰撞。教师应对策略:教师在巡视中发现这种情况时，可以适时介入:"I heard a lot of people saying space exploration is great. But remember, Emma had some very good points too. What about the problem of money? What about the danger to astronauts? Can anybody play the role of Emma in your group?" 通过教师的提示，引导学生从多角度思考问题。 八、板书设计 板书采用分区布局，共分为三个区域。 主板书区域位于黑板中央，上方工整书写课题： Unit 6 Beyond Earth Section A 2a-2e。课题下方分为两个对比栏。 左侧栏目标题为Mark's Opinions，下方依次书写:supports space exploration；helps us learn about the universe；helps find new resources；prefers robots for dangerous work。 右侧栏目标题为Emma's Opinions，下方依次书写:worries about the cost；money should be spent on Earth's problems；thinks about poverty and pollution。 两个对比栏中间画一条直线，上方标注"Comparing Opinions"，帮助学生直观理解两人观点的差异。 副板书区域位于黑板右侧，书写本课核心句型，包括: I think that... because... I believe... In my opinion... From my point of view... I agree with you, but... That's a good point. However... 板书下方标注一个提醒语句： Give a reason to support your opinion. 整个板书以人物观点对比为核心线索，配合核心句型支架，形成对课堂主要内容的直观呈现，方便学生随时参考和理解。 九、教学反思 本课时的教学设计围绕听力理解与口语表达两大核心任务展开，在任务链的搭建和课堂互动的组织方面进行了较为系统的思考。 从教学设计来看，本课遵循从背景激活到听前预测，从整体听音到细节获取，从模仿跟读到自主表达，最后到归纳总结的学习路径，各个环节之间逻辑连贯、梯度合理。听前预测环节的猜测活动有效降低了听力任务的难度，使学生在听音前已经对可能听到的内容有了心理预期。两遍听力任务的设置从宏观到微观，从人物匹配到细节梳理，实现了由浅入深的训练目标。角色扮演环节以2d对话为范本，通过模仿、朗读再到创编的步骤，逐步引导学生将输入的语言材料转化为自己的输出能力。 从学生活动的设计来看，个人思考、同伴交流、小组讨论、全班展示等多种组织形式交替出现，既保证了每个学生独立学习的机会，又提供了充分的交流和合作空间。在讨论话题的设置上，选择了与生活关联较强且具有一定趣味性的内容，有助于激发学生的参与意识。从课堂实施的效果来估计，大部分学生能够完成听力任务并积极参与口语活动，但部分基础薄弱的学生在信息记录和完整表达方面仍可能遇到较大挑战，这提醒教师在后续教学中需要特别关注这部分学生的课堂表现，适时给予个别帮助和鼓励。 从需要改进的方面来看，听力材料的利用深度还可以进一步加强，例如在完成基本听力任务后，可以增加一段关于听力文本中精彩表达的欣赏和仿写活动，帮助学生在理解内容的基础上进一步关注语言形式。口语活动的时间分配在实施过程中可能因学生参与热情高而出现超时现象，需要在真实教学中灵活调整，保证课堂节奏的紧凑和均衡。作业布置采用分层方式，既关注了全体学生的基本学习需求，也为学有余力的学生提供了拓展空间，在作业反馈环节需要及时收集学生的完成情况，为后续教学提供参考依据。 学科网（北京）股份有限公司 $
