【RSB学案36】人教版高中英语必修第二册 Unit2 Wildlife Protection 第1课时学案（Reading and Thinking 阅读精读课）

作者：Risibo

本套学案遵循日思搏英语学习法（Reasonable English）“背、悟、用”模式，构建实用高效的特色课堂。RSB即Recite（背诵）、Study（领悟）、Build（运用）。

一、狂背阶段·素材输入（课前预习完成）

本阶段核心：音、形、义、用四位一体绑定背诵，拒绝孤立记单词。

1.篇章音频狂背：听课本Reading and Thinking课文录音3遍。第1遍盲听抓主旨，了解作者在西藏观察藏羚羊的经历及藏羚羊保护的现状；第2遍逐句跟读，模仿语音语调；第3遍合书尝试复述事件脉络，标记卡顿的生词与长句。

2.核心词句狂背：聚焦本课8组核心词汇与短语，边读边在草稿本写例句，建立"词—句"关联。核心词：wildlife, protection, hunt, alarm, aware, average, concern, adapt核心短语：be aware of, on average, be concerned about, adapt to, under pressure, make profits, watch over

3.典型佳句狂背：提前背诵课文3个核心长句，做到流利口头复述，为课中真悟打基础。

二、真悟阶段·规律内化（课中探究完成）

本阶段核心：用理性思维拆解语言现象，归纳底层规律，标注考试易错陷阱。

（一）篇章真悟（落实RSB背悟用篇章秘笈）

本文是一篇自然保护主题的纪实散文，以作者的亲身经历为线索：

• 观察经历：作者在西藏高原观察藏羚羊，被其优雅与生存智慧所震撼

• 危机回顾：藏羚羊曾因非法猎杀数量锐减，濒临灭绝

• 保护措施：政府建立自然保护区，制定法律，志愿者参与保护

• 现状与反思：藏羚羊数量有所恢复，但保护仍需持续，人与自然应和谐共处

理性思考：自然保护类文本，阅读重点抓物种困境、保护措施、现状变化、作者观点。长难句处理遵循"找主干—拆修饰—理逻辑"三步法，先锁定主谓，再剥离定语从句、分词结构等修饰成分。

（二）典型佳句真悟（落实RSB背悟用典型佳句秘笈）

每句拆解"句式结构+语法规律+考试易错点"，从"看懂"到"吃透"。

1.To our left, snow‑capped mountains disappeared into clouds, which seemed almost close enough to touch.翻译：在我们左边，积雪覆盖的山脉消失在云层中，云层看起来近得仿佛触手可及。真悟解析：which引导非限制性定语从句，修饰先行词clouds；不定式短语To our left作地点状语。⚠️ 高考易错坑：非限制性定语从句不能用that引导。

2.Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.翻译：只有当我们学会与自然和谐共处时，我们才能不再成为野生动物和地球的威胁。真悟解析：Only+时间状语从句放句首，主句用部分倒装；stop doing sth停止做某事；be a threat to对……构成威胁。⚠️ 倒装考点：only+状语放句首，主句部分倒装，从句不倒装。

3.Hunters were shooting antelopes to make profits. Their habitats were becoming smaller as new roads and railways were built.翻译：猎人们为了牟利而射杀羚羊。随着新公路和铁路的修建，它们的栖息地变得越来越小。真悟解析：不定式to make profits作目的状语；as引导时间状语从句，表"随着"；过去进行时描述过去持续变化的过程。

课堂实操：合上书本，口头复述3个句子的结构规律，自行列举1个易错场景，完成"输入—拆解—内化"。

三、神用阶段·输出落地（当堂+课后练习）
