教学设计理念
以人与自然主题语境为引领,落实英语学习活动观,遵循 “学习理解 — 应用实践 — 迁移创新” 三层活动逻辑。依托塑料包装环保真实情境搭建词汇语义网,融合听说技能训练;凸显学生主体地位,通过小组合作、听力思辨、观点辩论、问题解决类活动,培养学生环保意识、批判性思维、跨文化交际与自主合作学习能力,依托听力技巧支架与功能句型支架实现语言输入向口语输出转化,落实英语学科四大核心素养。
教材分析
【What】本课围绕塑料包装环保争议展开听说教学,听力文本包含两组对话:①Kevin 与 Alicia 针对超市椰子塑料包装的正反观点辩论,区分支持 / 反对塑料包装的理由;②Lisa 和 Amy 讨论生活垃圾减塑、回收再利用方案。配套两大技能支架:Skill Builder(识别听力观点)、Talk Builder(提出与接纳建议功能句型),配套分层听力任务、口语小组讨论。
【Why】学生通过听力输入掌握环保话题词汇,学会区分正反观点、抓取听力细节;掌握提建议交际句型,提升听力抓取观点、口语表达建议的能力;树立减塑、垃圾分类、绿色消费的环保价值观,学会辩证看待塑料制品利弊。
【How】课堂遵循 “激活已有认知 — 听力分层输入 — 功能句型聚焦 — 口语真实输出” 主线;听力核心技能:识别说话人观点、通过语气 / 观点词区分立场;语言功能:提出、赞同、接纳环保相关建议;核心词块:convenient, environmentally friendly, recyclable, wasteful, keep product fresh, do away with packaging, refillable containers 等。

Activity 1 Activate and Share(Lead in 导入)
1. 小组讨论问题:Do you often use plastic packets and boxes? What are the advantages and disadvantages of using them?
2. 提供辅助词块:convenient, environmentally friendly, recyclable, wasteful, terrible for the environment, to keep product fresh/clean/lasting longer
3. 小组代表分享讨论结果,教师板书利弊词汇
答案参考:
Advantages: convenient, keep products fresh clean/lasting longer, some packaging is recyclable
Disadvantages: wasteful and unnecessary, terrible for the environment, hard to break down
习题无,以口头讨论输出为主
依托学生生活经验激活环保、塑料相关已知词汇,创设塑料包装话题情境,引出本课听力主题,为后续听力输入铺垫词汇基础
7min
Activity 2 Listen for Understanding 观点判断听力
听 Kevin 与 Alicia 对话,判断观点归属,填写 K/A
1 It is stupid to wrap coconuts in plastic.(K)
2 Plastic packaging keeps the product fresh.(A)
3 Plastic packaging is bad for the environment.(K)
4 The packaging should be recyclable.(A)
5 We should do away with packaging completely.(K)
6 Refillable containers are not convenient.(A)
技能支架讲解 Skill Builder Identifying Opinions:抓取观点词、关注升降调区分同意 / 反对
浅层听力训练,训练学生抓取说话人立场,落实 “识别听力观点” 核心听力技巧,初步区分两人对立观点
8min
Activity 3 Listen again 细节填空 + 角色扮演
听录音完成对话填空,区分 Kevin (反对)、Alicia (支持) 立场,之后两人一组角色扮演
填空答案:
Isn't this the most wasteful of packaging ever?
But it's completely unnecessary.It already has its own natural packaging .It's got a hard shell that's almost impossible to break!
A lot of the plastic used in packaging is not recyclable.It's terrible for the environment:Our oceans are polluted, and animals and birds end up dead as a result.
But there is a good reason.Supermarkets want to make sure that coconuts reach the consumer in good condition.The packaging helps to protect, the product for a long time.
But the plastic wrapping also stops damage.It stops coconut hairs from falling off during transport .And it keeps the coconut clean and fresh.
But let's be realistic:We still need packaging. We just need to use the right kind of packaging.
任务:小组分角色朗读 Kevin&Alicia 辩论对话
精听抓取细节信息,梳理双方完整论据;通过角色扮演内化辩论词汇与观点表达,深化辩证看待塑料包装的思维

1 What did Kevin see in the supermarket?
Answer: He saw coconuts wrapped in thin clear plastic packaging.
2 What does Kevin think about this?
Answer: He thinks it is wasteful and unnecessary, plastic pollutes oceans and harms wildlife.
3 What solution does Alicia suggest?

作业内容
作业设计意图
本节课作业二选一,为分层作业,难度有所区别。基础一般的同学可以选择作业一,基础较好的同学可以选择作业二。
分层二选一
基础层(作业一):5-6 句话介绍 3 条日常生活减塑方法,至少使用 5 个本课核心词块(convenient, recyclable, wasteful, keep fresh, do away with, environmentally friendly)
提高层(作业二):短文《My Solutions to Online Shopping Plastic Waste》80-100 词,包含:1. 网购塑料包装现状;2. 三条减塑方案;3. 个人环保倡议
参考答案
基础层
Plastic packets are convenient but wasteful and terrible for the environment. We should do away with unnecessary plastic wrapping. First, we can take recyclable cloth bags for shopping. Second, refuse plastic takeaway boxes and bring our own bowls to keep food fresh. Small changes can make our life more environmentally friendly.
提高层
My Solutions to Online Shopping Plastic Waste
Nowadays, online shopping creates tons of unrecyclable plastic packaging, which pollutes our planet.
I have three practical ideas to solve this problem. First, online shops should use paper boxes instead of plastic fillers. Second, we can choose stores that support green delivery without extra plastic bags. Third, we should reuse plastic packages to store small things.
I believe small actions from every customer will help cut plastic waste greatly.

教学反思
优点:
紧扣人与自然主题语境,落实三层英语学习活动观,实现听说闭环;依托听力、句型支架降低学习难度;辩论与减塑讨论融合语言学习与环保德育;分层作业适配不同学生,完成课内外知识迁移。
缺点:
辩论时间不足,内向学生缺少发言机会;听力基础弱的学生难以区分双方观点,无关键词提示;口语讨论仅机械套用句型,缺乏深度思辨。
改进:
课前发放听力关键词清单帮扶学困生;辩论设置同桌互助,预留准备时间;口语讨论增加反驳环节,深化辩证思维;增设课堂互评,提升全员参与度。
