二、设计背景与意图
(一)设计背景
1.课标依据。《义务教育英语课程标准(2022年版)》坚持核心素养导向,主张学生在主题意义引领下,通过学习理解、应用实践、迁移创新三类活动整合性地学习语言;本课属于“人与自然”主题范畴下“环境保护”的子主题,并要求学生“能读懂关于塑料污染的说明文,获取塑料污染现状、危害与应对措施的关键信息”,“能理解并运用 global、produce、ton、packaging、affect、kill、pollute、suffer、option、reusable、properly、solution、impact、reduce 等核心词汇与短语”,“能就减塑话题与同伴交流,表达自己的减塑做法,认识到塑料污染的危害,树立减少塑料使用、绿色生活的意识”。本课以“环境保护”为主题,以“一篇介绍塑料污染的现状、危害与解决措施的说明文”为载体,为落实上述要求提供了良好素材。
2.政策导向。“双减”政策要求把作业设计纳入教研体系,控制作业总量与完成时长,鼓励设计分层、个性化作业,切实减轻学生过重的课业负担,把时间还给学生。本课作业以读懂塑料污染说明文、提取现状—危害—措施的关键信息、用英语谈论减塑做法并制作减塑行动清单为载体,把语言学习与绿色生活的责任意识结合起来,力求轻负高质。
3.教材与学情。本课是冀教版(2024)八年级上册 Unit 8 Protecting the environment 的第2课时,课题为 Look at the plastic!,属于阅读课,语篇为一篇“说明文”。语篇开篇点明“在当今世界,塑料污染是一个全球性问题(In today's world, plastic pollution is a global problem.)”,“人类每年生产数百万吨塑料,其中大约一半用于包装商品,许多塑料制品在成为废物之前我们只使用过一两次(Humans produce millions of tons of plastic every year. About half is for packaging goods. We use many plastic products only once or twice before they become waste.)”;接着说明“塑料污染影响环境的自然美,更糟糕的是,每年有数百万动物被塑料杀死,塑料会在地下留存多年并污染土壤、水和植物,如果我们的环境受到损害,人类也将承受后果(Plastic pollution affects the natural beauty of the environment. Even worse, millions of animals are killed by plastic every year. Plastic will stay in the ground for years and pollute the soil, water, and plants. If our environment suffers, humans will do too.)”;随后提出问题“为什么我们不能干脆停止使用塑料呢(Why can't we just stop using plastic?)”,指出“饮料瓶和塑料袋确实便于携带、购买便宜,但它们并不是唯一的选择(They are indeed easy to carry and cheap to buy. But they are not the only option!)”,并给出建议:“自带购物袋、携带可重复使用的水瓶、选择包装更少的产品、学会正确回收塑料(Bring your own shopping bag instead of using a plastic one. Carry a reusable water bottle. Choose products with less packaging. Learn to recycle plastic properly.)”;结尾号召“让我们成为解决方案的一部分,日常习惯中的小小改变将对减少塑料垃圾产生巨大影响(Let's be part of the solution. Small changes in our daily habits will have a big impact on reducing plastic waste.)”。本课核心词汇为 global, produce, ton, packaging, goods, product, waste, affect, kill, pollute, suffer, cheap, option, reusable, properly, solution, impact, reduce 等;重点短语为 plastic pollution, a global problem, millions of tons of, package goods, become waste, affect the natural beauty of the environment, even worse, be killed by plastic, stay in the ground, pollute the soil, water and plants, stop using plastic, easy to carry, cheap to buy, not the only option, instead of, a reusable water bottle, products with less packaging, recycle plastic properly, be part of the solution, have a big impact on, reduce plastic waste 等;语言与语法重点为“一般现在时的被动语态(millions of animals are killed by plastic)”、“if 引导的条件状语从句及其“主将从现”原则(If our environment suffers, humans will do too.)”、“动词不定式(短语)作状语(easy to carry, cheap to buy)”以及“instead of + 动名词结构”。八年级学生“对塑料制品有丰富的生活体验”,也“对塑料污染问题有初步认知”,但“用英语快速捕捉说明文中的关键信息、准确表达减塑做法”仍需支持,分层作业有助于降低难度、人人有所得。
(二)设计意图
1.目标统领,分层进阶。以本课时学习目标为统领,依据英语学习活动的三个层级,把作业设计为“基础巩固层(学习理解)—能力提升层(应用实践)—拓展创新层(迁移创新)”三个梯度,让不同水平的学生都能“跳一跳,够得着”。
2.情境贯穿,读写结合。以“读塑料污染说明文—提取现状、危害与措施的关键信息—用英语谈论减塑做法—制作减塑行动清单”为真实情境主线,把语言学习与绿色生活的责任意识自然融合,实现读写结合、学用结合。
3.弹性选择,减负提质。基础巩固层、能力提升层为必做,拓展创新层为选做,允许学生根据自身水平自主选择,做到总量可控、时长可测,落实减负提质。
4.学评一致,以评促学。作业目标与课堂学习目标、学业质量要求一一对应,并配套可操作的分层评价量表,实现“教—学—评”一致,让评价真正促进学生学习。

六、试题详情
语篇材料
Read the passage and finish the tasks.
Look at the plastic!
In today's world, plastic pollution is a global problem. Humans produce millions of tons of plastic every year. About half is for packaging goods. We use many plastic products only once or twice before they become waste.
Plastic pollution affects the natural beauty of the environment. Even worse, millions of animals are killed by plastic every year. Plastic will stay in the ground for years and pollute the soil, water, and plants. If our environment suffers, humans will do too.
Why can't we just stop using plastic? Think about drinking bottles and plastic bags. They are indeed easy to carry and cheap to buy. But they are not the only option! Bring your own shopping bag instead of using a plastic one. Carry a reusable water bottle. Choose products with less packaging. Learn to recycle plastic properly.
Let's be part of the solution. Small changes in our daily habits will have a big impact on reducing plastic waste.

题组8 采访汇报(开放性任务,参考答案)
Hello, everyone! I'd like to share my ideas about reducing plastic with you. In today's world, plastic pollution is a global problem. Humans produce millions of tons of plastic every year, and millions of animals are killed by plastic. Even worse, plastic will stay in the ground for years and pollute the soil, water, and plants. So I try to reduce plastic in my daily life. I always bring my own shopping bag instead of using a plastic one, and I carry a reusable water bottle to school. I also choose products with less packaging and learn to recycle plastic properly. Small changes in our daily habits will have a big impact on reducing plastic waste. Let's be part of the solution! Thank you!

题组9 读写与跨学科实践(开放性任务,参考答案)
1. 完成调查表并计算参与率(示例):若被调查总人数为 40 人,做过“自带购物袋”减塑行动的有 24 人,则参与率 = 24 ÷ 40 × 100% = 60%。
2. 英语减塑行动清单示例(开放性答案):
My Plastic-reducing Action List
1. I always bring my own shopping bag instead of using a plastic one, because plastic pollution is a global problem.
2. I carry a reusable water bottle to school every day, so I don't need to buy plastic bottles.
3. I choose products with less packaging when I go shopping.
4. I learn to recycle plastic properly, because plastic will stay in the ground for years and pollute the soil, water, and plants.
5. If we do nothing, our environment will suffer. So let's take action and be part of the solution!
评价要点:①清单要素是否齐全(塑料污染的问题、具体做法、原因、倡议);②英语表达是否正确、得体;③调查结论是否合理、数据是否准确;④是否体现减少塑料使用、从我做起、从小事做起的意识与责任担当。
