To carry out the task, the government organised a group of 369 foresters, mostly in their 20s.）”；随后引用第一代护林员赵振宇的话““一开始，我没有意识到工作条件会如此恶劣，天气会如此糟糕。”（At the very beginning, I did not realise that the working conditions would be so harsh and the weather so bad.）”，并说明“但他们从未放弃，护林员们坚持不懈，克服了这片土地带来的挑战，他们利用科学技术帮助树木在恶劣条件下存活（But they never gave up. The foresters carried on, overcoming the challenges of the land. They used science and technology to help trees to survive harsh conditions.）”；接着指出“塞罕坝人民用他们的心血和智慧努力了半个多世纪，塞罕坝精神激励着护林员们完成这项艰巨的任务（The Saihanba people worked hard with their hearts and minds for more than half a century. The Saihanba Spirit inspired the foresters to complete the difficult task.）”；结尾说明“塞罕坝现在是世界上最大的人工林，它在环境保护方面发挥着重要作用，人们可以在那里享受新鲜空气、聆听鸟儿鸣唱、欣赏美丽的风景（Saihanba is now the largest human-made forest in the world. It plays an important role in environmental protection. People can enjoy fresh air, birds singing, and beautiful scenery there.）”。本课核心词汇为 locate, hardly, wasteland, task, forester, harsh, overcome, challenge, survive, century, spirit, inspire 等；重点短语为 be located in, in the far-northern part of, around the late 1950s, hardly see, change...into..., carry out the task, a group of, mostly in their 20s, at the very beginning, never give up, carry on, overcome the challenges, use science and technology, survive harsh conditions, more than half a century, inspire sb. to do sth., complete the difficult task, play an important role in, enjoy fresh air and beautiful scenery 等；语言与语法重点为“动词不定式（短语）作目的状语（To carry out the task...；use science and technology to help trees survive）”、“过去分词短语作后置定语（located in the far-northern part of Hebei Province）”、“现在完成时与现在完成进行时（has become...; have been working...）”、“inspire sb. to do sth. 结构”以及“一般过去时的被动语态（was organised）”。八年级学生“对植树造林、绿色环保有一定的生活认知”，也“对艰苦奋斗的感人故事兴趣浓厚”，但“用英语快速梳理说明文的时间线索、准确运用动词不定式表目的”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“读塞罕坝绿色奇迹语篇—梳理时间线、提取关键信息—用英语讲述塞罕坝故事—制作绿色行动卡”为真实情境主线，把语言学习与生态建设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。 三、作业目标 （一）总体目标（核心素养四维度） 1．语言能力：能正确认读、拼写并运用本课核心词汇 locate, hardly, wasteland, task, forester, harsh, overcome, challenge, survive, century, spirit, inspire 以及重点短语 be located in, in the far-northern part of, around the late 1950s, hardly see, change...into..., carry out the task, a group of, mostly in their 20s, at the very beginning, never give up, carry on, overcome the challenges, use science and technology, survive harsh conditions, more than half a century, inspire sb. to do sth., complete the difficult task, play an important role in, enjoy fresh air and beautiful scenery；能读懂介绍塞罕坝变迁的记叙说明文，获取时间线索、建设者努力与塞罕坝精神的关键信息；能理解并运用“动词不定式（短语）作目的状语”、“过去分词短语作后置定语”、“现在完成时”、“inspire sb. to do sth.”以及“一般过去时的被动语态”；能用 Saihanba is located in... / To carry out the task, ... / They used science and technology to... / The Saihanba Spirit inspired... to... 等功能句讲述塞罕坝故事；能结合所学，写出一段介绍塞罕坝绿色奇迹的短文并制作绿色行动卡。 2．文化意识：通过了解塞罕坝从荒原变为世界最大人工林的历程，“认识到生态建设成就来之不易，懂得艰苦奋斗、久久为功的意义”，“感受塞罕坝精神，树立保护生态环境、建设美丽中国的意识，增强民族自豪感与社会责任感”，“愿意从身边小事做起，主动践行绿色行动”。 3．思维品质：能借助时间线梳理“20世纪50年代末—1962年—半个多世纪—现在”的发展脉络，通过提取、比较与归纳说明文信息，理清语篇的“过去—变迁—现在”结构，发展提取信息、比较分析与有条理表达的能力。 4．学习能力：能借助表格、时间线等工具梳理记叙说明文信息；能主动运用读前预测、读中抓关键词、读后归纳等策略；能运用提示词与句型完成表达，主动反思并优化自己的学习方法，增强自主学习意识与合作交流能力。 （二）分层目标 1．基础巩固层（★，必做）：巩固本课核心词汇、短语的认读与拼写；读懂语篇大意，获取塞罕坝变迁的时间线索与关键信息，完成选择与正误判断。 2．能力提升层（★★，必做）：能在语境中正确运用目标词汇、短语，掌握动词不定式作目的状语、过去分词短语作定语、现在完成时与 inspire sb. to do sth. 等结构的用法，完成选择、词形变化、连词成句与完成句子、短文填空等任务，并复述语篇的主要信息。 3．拓展创新层（★★★，选做）：能综合运用所学语言，完成采访汇报、读写表达与跨学科实践任务，谈论塞罕坝绿色奇迹并制作绿色行动卡，完成一次全班绿色行动参与情况小调查，发展迁移创新能力与生态责任意识，体会“保护环境、从我做起、从小事做起的责任担当”。 四、作业内容与目标对应表 本作业共设 3 个层级、9 个题组，各题组与作业目标、主要题型的对应关系如下表所示。 序号 题组名称 对应作业目标 主要题型 完成层级 预计用时 1 词汇过关：火眼金睛认单词 能正确认读、拼写本课核心词汇 单词拼写 基础层★必做 2分钟 2 短语速记：连线搭配 能掌握本课核心短语并理解其含义 短语连线 基础层★必做 2分钟 3 阅读理解：绿色奇迹塞罕坝与信息提取 读懂语篇，提取塞罕坝变迁的时间线索与关键信息 选择+正误判断 基础层★必做 6分钟 4 单项选择：语法与语境 在语境中正确运用词汇、短语与目标结构 单项选择 提升层★★必做 3分钟 5 词形变化 正确运用词形变化与目标词汇形式 词形变换 提升层★★必做 4分钟 6 连词成句与完成句子 运用目标句型重组信息、完成句子 连词成句+完成句子 提升层★★必做 4分钟 7 短文填空：绿色奇迹塞罕坝 在完整语篇中运用核心词汇与语法 短文填空 提升层★★必做 4分钟 8 采访汇报：我心中的绿色奇迹 综合运用本课语言，讲述塞罕坝故事并表达行动意愿 口语表达/微型汇报 拓展层★★★选做 8分钟 9 读写与跨学科实践：制作绿色行动卡 结合社会调查完成读写与跨学科探究 读写+跨学科实践 拓展层★★★选做 7分钟 五、作业评价 （一）评价原则 1．“教—学—评”一致：评价标准与作业目标、学业质量要求一一对应。 2．多元主体：学生自评、同伴互评与教师评价相结合，避免单一评价。 3．分层标准：不同层级使用不同的评价标准，重在激励与发展，让每个学生都能获得成功体验。 4．过程与结果并重：既关注答案的正确性，也关注口语表达、绿色行动卡的表现以及主动践行绿色生活的责任担当意识。 （二）评价方式 1．学生自评：完成作业后用“★—★★—★★★”自评，并写下“我最想说的一句绿色行动宣言”与“我还想改进的地方”。 2．同伴互评：口语汇报与书面表达由同伴依据量表互评，给出“一个亮点+一条小建议”。 3．教师评价：以星级加描述性评语为主，基础层重准确，提升层重运用，拓展层重绿色行动卡与介绍短文的条理表达、信息完整以及保护环境、从我做起情感的表现。 （三）分层评价量表 评价维度 ★ 基础达标 ★★ 良好 ★★★ 优秀 词汇短语掌握 核心词汇短语的拼写、词义匹配正确率达到70%及以上，少量错误经提示后可自行订正。 核心词汇短语的拼写、词义匹配正确率达到90%及以上，能在句子中正确使用。 核心词汇短语全部掌握，能在语篇与真实表达中灵活运用，没有语言错误。 阅读与信息提取 能读懂语篇大意，提取部分信息，3个以内的细节题出现错误。 能完整读懂语篇，准确提取塞罕坝变迁的时间线索与关键信息，正误判断完全正确。 能结构化梳理“过去—变迁—现在”时间线，自主画出思维导图，并概括语篇的绿色奇迹脉络。 语法与语用运用 能正确使用 overcome、inspire 等词的基本形式，出现少量错误。 能正确运用本课词汇、短语与目标结构，能使用动词不定式作目的状语、inspire sb. to do sth. 等结构，语法错误少于2处。 能正确、自然地运用目标语言，写出结构清晰、信息完整、语言得体的介绍短文，动词不定式表目的与现在完成时使用准确。 拓展与表达 能写出塞罕坝故事的主要信息，句子基本完整。 能用3-5个完整句子讲述塞罕坝故事，条理清楚、表达连贯。 能自信地完成1分钟采访汇报，介绍清楚、信息完整，绿色行动卡要素齐全、结论合理，生态责任意识表达真切。 （四）综合评价与结果运用 本次分层作业的综合评价采用多元加权计算方式，计算公式如下： 最终评价结果以星级等级呈现，不排名、不公开学生个体分数，重点反馈“我有了怎样的进步”和“下一步怎么努力”，将评价结果转化为后续课堂分层指导的依据：对基础仍有困难的学生进行词汇与目标句型的针对性辅导，对学有余力的学生引导其进行更深入的生态调查与展示分享。 六、试题详情 语篇材料 Read the passage and finish the tasks.
