Unit4 第8课时 Section B (Project)课件 2026-2027学年人教版英语九年级上册

该初中英语课件围绕“是否需要记忆”的辩论主题，涵盖必要词汇（如necessary, memorize）、宾语从句及辩论表达。课堂导入通过π的提问（What is this? Can we find it online?）引发兴趣，衔接4a辩论问题，再经4b分组列理由、4c数据支撑，构建从兴趣激发到知识应用的学习支架。 其亮点在于构词法词汇教学（如memorize=memor+ize解析）提升语言能力，辩论活动结合科学家实验数据（歌唱与阅读记忆效率对比）培养思维品质，分层作业（基础默写、提升写作、拓展辩论准备）发展学习能力。学生能提升逻辑表达与自主学习能力，教师可高效开展思辨教学。

This is pi ( ). 2.Can we find it online? Yes, we can. 3.Can you recite it? Yes, I can. / No, I can't. 4a Think about this question: “Is it still necessary to memorize things when they can be found online?” Yes,We need to memorize things. No,We don’t need to memorize things. What is your opinion? I think we still need to memorize some things, but not everything. 4b Form two groups based on different opinions. Add at least three reasons to support your opinion. Opinion Reason We need to memorize things. We don’t need to memorize things. Memorizing things trains our brain. Everything we need is already online. If we memorize things, we can use them right away. Memorizing things takes up too much time. Sometimes online information is lost. What will we do then? Thinking skills are much important than memory. 1.记忆事物能够锻炼我们的大脑。 2.如果我们熟记知识,就能立刻运用它们。 3.网络上的信息有时会消失,到那时我们该怎么办? 4.我们所需的一切信息在网上都能找到。 5.背诵知识会占用大量时间。 6.思维能力远比记忆力更加重要。 Memorizing things trains our brain. If we memorize things, we can use them right away. Sometimes online information is lost. What will we do then? Everything we need is already online. Memorizing things takes up too much time. Thinking skills are much more important than memory. Translate 4c Use examples and data to support your opinions. Reason 1: Memorizing helps us learn faster. Scientists did an experiment with young children. One group learned a poem by singing. The other group learned it by reading again and again. The singing group finished in 11.6 minutes. The reading group finished in 25.4 minutes. After 6 months, the singing group still remembered the whole poem. But only 32% of the reading group remembered it. So, good memory helps us learn things more than twice as fast. Reason 2: Basic knowledge is the base for thinking. A Harvard professor said that we need facts in our mind to think well. Without facts, we cannot do higher thinking. For example, try to remember these letters: N B C D N F H P I. It's hard. But if you group them as CNN, FBI, PHD, you can remember them easily. Why? Because you already know these names. So, if you have background knowledge, you understand new things better. Memory gives us that knowledge. Reason 3: Memorizing makes our brain faster. When we memorize things like multiplication tables, we can use them quickly. For example, if you know 7 8=56, you don't need to count. You can just use it and move on to harder math problems. Studies show that students who have memorized basic math facts can focus better on understanding new ideas. Conclusion We still need to memorize important things. It helps us learn faster, think deeper, and use our brain more quickly. Even though we can find many things online, we need some knowledge in our head to really understand the world. 4d Have a debate on the question. Each student takes turns to speak. 一、开篇提出观点 In my opinion, …在我看来,…… My opinion is that we need to memorize things. 我的观点是我们需要记忆知识。 3.I believe that …我认为…… 4.From my point of view, …依我之见,…… 二、阐述理由(核心高频) One reason is that …第一个理由是…… Besides, … / What’s more, …此外,…… Another important point is that …另一个重点是…… The main reason is that …主要原因是…… 三、举例论证 For example, …例如…… Let me give you an example. 让我举一个例子。 Take … as an example.以…… 为例。 四、反驳对方观点 I don’t agree with you.我不同意你的看法。 But I think your idea is not right.但是我认为你的观点不对。 However, we should think about …然而,我们应当考虑…… What you said sounds good, but …你说的听起来不错,但是…… 五、提问对手 Have you ever thought about …?你有没有考虑过……?

We should know what we need to keep in mind. 3. 核心短语 memorize things 记忆内容 train our brain 锻炼大脑 take up time 占用时间 right away 立刻,马上 short-term memory 短期记忆 long-term memory 长期记忆 acquire new knowledge 获取新知识 improve memory 提升记忆力 depend on online information 依靠网络信息 4. 辩论表达模板 观点开头:My opinion is that… / I believe that… 理由拓展:One reason is that… Besides,… What’s more,… HOMEWORK 基础层(全体必做) 背诵本课核心短语,默写 5 个短语 + 中文意思。 仿照模板写 3 个含有宾语从句的句子,表达你对 “记忆” 的看法。 提升层(选做,建议中等学生完成) 开展小型思辨写作: Write 80 词短文:Do you think students should memorize English words? 要求:至少包含 1 处宾语从句,给出 2 个理由。 拓展层(挑战选做,学有余力) 1.模拟辩论准备《选择立场:We don’t need to memorize lots of information. 2.整理 3 条支撑理由,并且为每条理由配上简单例子,准备课堂口头发言。 Going over what you learned gives you new ideas. Unit4 If you review what you have learnt, you will acquire new knowledge more effectively. 如果你复习所学的内容,你将会更有效地获得新知识。 温故而知新。 $
