内容正文:

Unit 7 What's the highest mountain in the world? Section A 3a-3c: Qomolangma - The Most Dangerous Mountain in the World? 探索精神 1.7.2013 大家好,欢迎来到今天的英语课堂。今天我们将一起探索世界之巅——珠穆朗玛峰。它不仅是地球上最高的山峰,也被称为“世界上最危险的山”。这节课,我们将通过阅读一篇文章,深入了解这座神奇的山峰以及那些勇敢攀登它的人们。让我们一起开启这段探索之旅吧! ‹#› The Spirit of Exploration: Reinhold Messner Born in 1944, this Italian mountaineer and explorer is widely hailed as one of the greatest climbers of all time. His life embodies the relentless human spirit to challenge nature and transcend perceived limits. 1978 · First Oxygenless Pioneered the ascent of Everest without supplemental oxygen, rewriting the rules of high-altitude climbing forever. 1980 · Solo & Alone Achieved the impossible: the first solo ascent of Everest without oxygen, a feat of unparalleled courage and skill. The 14 Giants Became the first person to conquer all 14 mountains on Earth that exceed 8,000 meters in height. Messner is the "superhero" of mountaineering, shattering the myth of "impossible." His story teaches us that unwavering faith and relentless effort turn distant dreams into reality. Reflect: What words describe Messner (e.g., brave, determined)? Why do you think people risk their lives to explore the unknown? 1.7.2013 在正式阅读课文之前,让我们先来认识一位登山界的传奇人物——雷纳·梅斯纳尔。他被认为是有史以来最伟大的登山家之一。他完成了许多前所未有的壮举,比如首次无氧登顶珠峰,以及单人无氧登顶。他的故事完美诠释了什么是探索精神。看到这些成就,你想到了哪些词?你认为人们为什么愿意冒着生命危险去攀登这些危险的山峰呢? ‹#› Messner's Philosophy: Alpine Style 在群山的沉默中,梅斯纳尔以极简的装备和纯粹的意志,重新定义了人与山峰的关系。他是“阿尔卑斯式登山”最坚定的早期倡导者,让攀登回归其本质——一场关于自我、勇气与极限的孤独对话。 01. 核心理念:自给自足的纯粹攀登 强调不依赖夏尔巴协作、搬运及外界补给,仅用轻量化装备,凭借自身技能与判断完成全程。这是对登山者综合能力的终极试炼,也是对山峰最谦卑的致敬。 概念辨析 切勿混淆“阿尔卑斯式”与“喜马拉雅式”。后者常依赖大量人力与物资支持,而前者则回归登山的原始形态,是真正的“无补给生存挑战”。 生活化类比 如同在游戏中选择“硬核生存模式”:不使用任何道具、攻略或外挂,仅凭对规则的理解和自身反应,从零开始通关,每一步都充满未知与挑战。 “He became one of the earliest and strongest proponents of what came to be called the 'Alpine' style of mountaineering...” — Britannica 思考:你认为哪种登山方式更具挑战性?这种“硬核”攀登需要哪些个人品质支撑? 1.7.2013 梅斯纳尔不仅是一位伟大的登山家,他还倡导一种特殊的登山哲学——“阿尔卑斯式登山”。这种方式强调自给自足,尽可能少地依赖外界帮助。这就像玩游戏选择“硬核模式”,完全靠自己。大家想一想,你认为哪种登山方式更具挑战性?要进行这种“阿尔卑斯式”攀登,需要具备哪些个人品质呢? ‹#› 世界之巅:珠穆朗玛峰 图为珠峰“日照金山”的壮丽景象。在藏语中,它被称作“第三女神”,是无数探险家心中的终极梦想,也是地球海拔的最高极点。 “地球第三极”的精神象征 珠穆朗玛峰(Mount Everest)是地球海平面以上的最高峰。它不仅是一个地理坐标,更象征着人类挑战自我、突破极限的无畏精神,如同体育界的奥运金牌、学术界的诺贝尔奖,代表着领域内的至高成就。 极致海拔 最新测量高度为8,848.86米(29,031.7英尺),是地球表面的最高基准点。 神圣疆界 屹立于中国与尼泊尔边境,地处雄伟的喜马拉雅山脉中段,是两国共有的自然瑰宝。 文化印记 藏语意为“第三女神”,尼泊尔语称其为“天空女神”,承载着深厚的民族文化内涵。 课堂思考: 看着珠峰的照片,你会用哪些词语形容它?(如:majestic, dangerous, cold...)你还知道哪些关于珠峰的探险故事或地理知识? 1.7.2013 现在,让我们将目光聚焦于世界之巅——珠穆朗玛峰。它的最新高度是8848.86米,位于中国和尼泊尔的边境。它在不同文化中有不同的名字,比如在藏语中被称为“第三女神”。关于珠峰,你都知道些什么?看着这张壮丽的照片,你会用哪些词来形容它呢? ‹#› Brainstorming: Words about Qomolangma Core Purpose This activity aims to activate students' prior knowledge by listing words and ideas related to Qomolangma. It serves as a "thought warehouse" to unpack what they already know, bridging gaps and building connections for the upcoming reading task. Word Categories Location:China, Nepal, Himalayas Features:High, snowy, cold, massive Activities:Climbing, exploring, hiking Feelings:Dangerous, exciting, amazing Interactive Guide "Let's create a mind map together! Shout out any words that come to mind." Write responses on the board and categorize them. Encourage free association—even seemingly random words can spark meaningful connections for students. Teaching Tip:If students mention inaccurate information (e.g., "It's in Tibet only"), gently guide them to the correct facts. Focus on building confidence in vocabulary output over perfect accuracy at this stage. 1.7.2013 接下来,我们来做一个头脑风暴活动。让我们围绕“珠穆朗玛峰”这个主题,尽可能多地说出你能想到的词语。我们可以把这些词分类,比如地理位置、特征、相关活动和感受。请大家踊跃发言! ‹#› Predicting from the Title What is Predicting? It is a vital reading strategy: analyzing the title to guess what a text is about before reading. It sparks curiosity and helps focus on key information during reading. Analogy: Just like watching a movie trailer—you use the title and snippets to infer the genre and plot before seeing the full film. Case Study "Qomolangma - the Most Dangerous Mountain in the World?" The "?" is critical! It hints the article may not just state facts, but debatewhetherit is truly the "most" dangerous, exploring different perspectives of its risks. Think & Discuss 1. What do you think the article will focus on, based on the title? 2. Why do you think the writer uses a question mark instead of a period? Key Takeaway: Never ignore punctuation in a title—it is a powerful clue for predicting meaning. 1.7.2013 在阅读文章之前,我们先来看一下它的标题:“Qomolangma - the Most Dangerous Mountain in the World?”。请大家仔细阅读这个标题,思考一下,这篇文章可能会讲些什么?特别注意标题末尾的问号,你认为作者为什么要用问号呢?这是一种非常重要的阅读技巧——预测。 ‹#› New Words: mountain, climbing 珠穆朗玛峰(Mount Qomolangma)是世界最高峰,也是 mountain 的极致象征。登山不仅是运动,更是对自我极限的挑战。 ▌ 核心语境 & 易错辨析 "Mountain climbing is a popular activity." 注意辨析:mountain (宏伟的山)与hill (低矮的小山丘)的区别,前者更具规模感。 01. mountain /ˈmaʊntən/ 本单元核心话题词,指高大的山脉或山岳。它是自然界的“摩天大楼”,代表着宏伟与壮丽,是登山运动的载体。 02. climbing /ˈklaɪmɪŋ/ 动名词,指攀登、登山运动。就像沉浸式的攀岩游戏,强调一步步向上的动作与挑战自我的过程,是户外爱好者的热门选择。 Class Interaction: Can you name some famous mountains in China? Do you like mountain climbing? Share your reasons with a partner. 1.7.2013 现在我们来学习一些新单词。首先是 mountain,山,这是我们本单元的核心词汇。climbing 是登山运动。大家能说出中国一些著名的山脉吗?你喜欢登山吗?为什么? ‹#› New Words: dangerous 正如巍峨险峻的雪山,登山运动本身充满了未知的风险。dangerous 作为核心形容词,精准描绘了这类事物的固有属性。 01. 核心释义 (adj.) 意为“危险的;有风险的”,用于描述事物本身具有会引起伤害或损害的性质。 例句:Mountain climbing is a dangerous sport. 02. 易混淆点辨析 dangerous vs. in danger:前者修饰事物,表“本身有危险”;后者描述状态,表“(人/物)处于危险之中”。 类比:在结冰路面骑车是 dangerous 的行为,而骑车的人可能会 be in danger。 03. 互动与思考 尝试回答:你能说出其他危险的运动吗?并翻译:“这个地方很危险,我们现在处于危险之中。” 1.7.2013 下一个词是 dangerous,危险的。这是课文标题中的关键词。请注意区分 dangerous 和 in danger。dangerous 形容事物本身,比如“危险的运动”;而 in danger 形容状态,比如“处于危险中”。大家能说出其他一些危险的运动吗?试着翻译一下这个句子:“这个地方很危险,我们现在处于危险之中。” ‹#› New Words: thick, cover 经典语境: "Thick clouds cover the top of the mountain."(浓密的云层覆盖了山顶。)此句是描述山中环境的典型句式,展现了两个核心词的用法。 易错辨析: 动词 "cover" 意为“覆盖”,而作名词时则指“封面;盖子”。注意区分语境,避免混淆词性。 01. thick (adj.) 意为“厚的;浓密的”。在登山场景中,thick clouds 是重要的环境特征,也是潜在的危险因素。可以类比生活中的“一碗浓稠的粥”,形象理解其“不透明、密度大”的特质。 02. cover (v.) 意为“覆盖”,常用于描述云、雪、植被等遮蔽山体或物体的状态。就像我们给书本“包上书皮”一样,强调从表面将事物遮盖住的动作或结果。 互动思考:What does "thick fog" mean? Can you make a sentence with "cover" to describe a scene you know? 1.7.2013 接下来两个词是 thick 和 cover。thick 是形容词,意思是“厚的、浓密的”,比如课文里提到的 thick clouds,浓密的云层。cover 是动词,意思是“覆盖”。大家想一想,“大雾”用英语怎么说?你能用 cover 造一个句子吗? ‹#› New Words: freezing 高原冰川上的登山者正艰难跋涉。在课文语境中,“freezing weather”正是他们面临的最大自然考验之一。 01. 核心释义:极冷的 (Adjective) 形容气温极低,是描述恶劣天气的高频词。例句:“The freezing weather makes it hard to climb.” (严寒的天气让登山变得十分困难。) 02. 易错点:freezing (adj.) vs. freeze (v.) Freezing 表示“极冷的”(描述状态),而 freeze 是动词,意为“结冰;凝固”(描述动作)。可以类比“冬天舔铁栏杆瞬间被粘住”的感觉来记忆。 思考与表达:What does "freezing weather conditions" mean? Try to make a sentence using "freezing" to describe your winter experience. 1.7.2013 我们来看 freezing 这个词。它是形容词,意思是“极冷的”。课文中提到 freezing weather conditions,也就是极寒的天气状况。注意它和动词 freeze(结冰)的区别。大家能用 freezing 造一个关于冬天的句子吗? ‹#› New Words: condition, include 核心概念:掌握名词与动词的用法,精准描述复杂情境与事物构成。 例句:Serious difficulties include freezing weather conditions and heavy storms. 易错点:区分动词 include 与介词 including,注意在句中的语法位置。 01. condition (n.) 意为“条件;状况”,常用来描述天气、环境、健康等综合状态。 💡 类比理解:就像游戏中的“环境设定”,雨天、雾天等天气状况会直接影响行动难度,正如生活中的环境条件影响我们的决策。 02. include (v.) 意为“包括;包含”,用于列举整体中的组成部分,是表达事物构成的核心动词。 🍗 类比理解:如同点一份“全家桶套餐”,里面自然包括汉堡、炸鸡和可乐,直观体现了从整体到具体组成的关系。 观察与表达:What are the weather conditions like today? 试着用英语描述你看到的天气状况。 造句挑战:用 include 介绍你的兴趣爱好,参考:My hobbies include reading and playing basketball. 1.7.2013 condition 和 include 也是两个重要的词。condition 是名词,指“条件、状况”,比如 weather conditions 天气状况。include 是动词,意思是“包括”。今天的天气怎么样?你能用 include 造一个句子吗? ‹#› New Words: storm 暴风雪常伴随着严寒与狂风,是登山者面临的重大自然挑战。画面中巍峨的雪山在风暴笼罩下更显险峻,直观展现了 storm 的磅礴气势。 01. 核心释义与意象 storm (n.) 指暴风雨、暴风雪,是描述剧烈大气扰动的统称。可以将其生动类比为:天空在“发脾气”,往往伴随着狂风大作、电闪雷鸣或暴雪,极具破坏力。 02. 语境运用与易错辨析 例句:Serious difficulties include freezing weather conditions and heavy storms. 辨析:storm 侧重风暴本身(风为主),而 rainstorm 特指暴雨(雨为主)。 互动思考:Have you ever experienced a heavy storm? What was it like? 1.7.2013 storm 这个词指的是“暴风雨”或“暴风雪”。在登山中,遭遇 heavy storms 是非常危险的。大家经历过暴风雨吗?那是什么样的感觉? ‹#› New Words: succeed, success 核心认知与实例 掌握“成功”相关的动词与名词形态,是理解英语语境中行为与结果的关键。 【经典例句】 "She was the first woman to succeed in reaching the summit alone." succeed (动词) 指达成目标、实现愿望的动作或过程。常接介词in构成短语,强调“做成某事”。 【类比】 如同登山者克服险阻,最终抵达顶峰的行动过程。 success (名词) 指成功的状态、结果,或一件成功的事/人。是动词 succeed 对应的名词形式。 【类比】 如同赢得一场重要比赛后,手中紧握的奖杯与荣誉本身。 ⚠️ 易错点辨析 注意词性区分:succeed (v.) 是动作,success (n.) 是结果,successful (adj.) 是状态(如 a successful person)。切勿混淆使用。 🤔 课堂思考 What does it mean to “succeed in doing something”? What is the key to success in your opinion? (Share your ideas.) 1.7.2013 succeed 和 success 都和“成功”有关。succeed 是动词,比如 succeed in doing sth. 成功做成某事。success 是名词。请大家思考一下,“成功做成某事”意味着什么?你认为成功的关键是什么? ‹#› New Words: achievement 正如图片中登山者站在雪山之巅,成就(achievement)不仅是一个结果,更是汗水与坚持凝结成的勋章,是对自我极限的突破。 01. 核心释义 (n.) 意为“成就、成绩、功绩”,指通过努力、技能或勇气成功完成的事情,是对长期付出的回报,强调结果的价值与重要性。 02. 经典语境 “Reaching the top is a great achievement.”(登顶是一项伟大的成就。)此句生动展现了该词在描述重大目标达成时的用法。 趣味类比 这就像你在游戏中解锁了最难的成就奖杯,每一个奖杯背后,都是无数次尝试与坚持的见证。 课堂思考 “What is your greatest achievement so far in your study or life?” 试着和同桌分享你的答案吧。 1.7.2013 achievement 是名词,意思是“成就”。登顶珠峰就是一项伟大的 achievement。大家迄今为止最大的成就是什么呢?可以和同桌分享一下。 ‹#› New Words: challenge 正如登山者向险峻高峰发起冲击,我们在生活中也时刻面临着对自我能力的探索与突破。 challenge (v. / n.) — 挑战,质疑 指激发个人潜能、突破自我极限的行为或过程。它不仅是名词,也常用作动词,表示“向...发起挑战”或“考验能力”。 经典例句:"People want to challenge themselves." (人们想要挑战自我。) 类比理解:就像选择学习一门极难的乐器,明知过程艰辛,但正是这种“挑战”带来的征服感,构成了成长的核心动力。 ⚠️ 语法易错点 不要混淆其名词与动词用法。作名词时可加冠词(a/the),作动词时直接接宾语,如 challenge limits。 🤔 课堂思考 What does it mean to 'challenge yourself'? Can you share a personal example in your life? 1.7.2013 `challenge` 这个词非常重要,它既可以作动词,也可以作名词,都表示“挑战”。课文中提到人们登山是为了 `challenge themselves`,挑战自我。你认为“挑战自我”意味着什么?能举个例子吗? ‹#› New Words: spirit 核心释义 · 核心词汇 spirit (n.)精神,意志 这是本文主旨升华的关键。它代表着一种内在的驱动力,支撑着人们在困境中坚守信念,是超越物质层面的核心力量。 语境类比 · 具象理解 经典例句: "The spirit of the climbers shows us never to give up." 类比:如同球队的“队魂”,即便比分落后,依然团结拼搏、永不言败,这种精神能凝聚力量,创造奇迹。 辨析思考 · 深度探究 易错辨析: spirit (精神/意志) 侧重信念与品格;soul (灵魂) 侧重生命本质或心灵。 Q: What kind of 'spirit' do you think the climbers have? 总结:Spirit 是抽象的精神力量,是文章的“眼”。理解登山者的精神,即是理解人类面对自然与困境时,那份不屈的意志与永恒的追求。 1.7.2013 spirit 是名词,意思是“精神、意志”。这是本文主旨升华的核心词汇。登山者的 spirit 告诉我们永不放弃。你认为登山者们拥有什么样的精神呢? ‹#› New Words: give up 核心释义与用法 意为“放弃(努力、尝试、信仰等)”。后接名词、代词或动名词 (doing)作宾语,不可接不定式。这是考试中常见的易错点,需特别记忆。 经典语境例证 "We should never give up trying to achieve our dreams." 这句话体现了面对梦想时的坚定态度。就像攀登高峰,即使路途艰险,也不轻言放弃,这正是“永不言弃”的精神内核。 生活化的类比 就像挑战一个极难的游戏关卡,即使失败了很多次,但你依然选择继续尝试,而不是直接退出游戏——这就是拒绝"give up"。它代表着一种不向困难妥协的选择。 课堂思考:When is it good to "give up"? And in what situations should you "never give up"? 1.7.2013 `give up` 是一个非常常用的动词短语,意思是“放弃”。课文告诉我们 `never give up`,永不放弃。大家思考一下,在什么情况下“放弃”是明智的?而在什么情况下我们应该“永不放弃”? ‹#› New Words: achieve 核心释义 achieve (v.):实现,达到 类比生活中的场景:就像经过日复一日的练习与坚持,终于稳稳学会骑自行车的时刻,那是能力与目标的完美契合。 用法与案例 经典例句: We should never give up trying to achieve our dreams. ⚠️ 易错提示: 常接抽象名词,如 dream, goal, success 等,侧重通过努力获得预期结果。 互动时刻 What is your dream? How will you achieve it? 试着用 achieve 造句,分享你的目标和实现它的计划,让梦想有迹可循。 要点总结:achieve 强调“达成、实现”,是连接现实与理想的桥梁。在写作中,用它搭配 dream 或 goal,能让文章的情感和主题更具力量。 1.7.2013 achieve 是动词,意思是“实现、达到”,常与 dream 或 goal 搭配。你的梦想是什么?你将如何去实现它? ‹#› New Words: force force (n.):力量,势力 用于描述物理或精神上的力量,尤指人与自然对抗时展现出的强大势力,如台风、地震等自然伟力。 "Humans can be stronger than the forces of nature." 人类的意志与协作,有时能超越看似不可抗拒的自然之力。 用法警示:当 "force" 特指“自然的力量”或“势力”时,习惯使用复数形式"forces"。 Class Discussion: What are the "forces of nature"? Can you name some examples in your life, like typhoons, earthquakes, or wildfires? 1.7.2013 最后一个词是 force,名词,意思是“力量”。课文中提到 the forces of nature,自然的力量。注意这里用了复数形式。大家能说出一些自然的力量吗?比如台风、地震等。 ‹#› Reading Task 1: Skimming 核心策略与定义 What is Skimming? Reading quickly to grasp the main idea without understanding every single word. ⚠️ Common Pitfall: Avoid reading word by word. Focus on topic sentences and key structures. 任务:段落大意匹配 Para. 1:Introduce basic facts and potential dangers of climbing. Para. 2:Recall historical achievements of brave climbers. Para. 3:Explore the great spirit behind their challenging journeys. 方法类比与技巧 📖 Life Analogy: It is like reading a book's table of contents first. You get a general idea of what the book is about without reading every chapter in detail. 💡 Key Skill: Pay attention to the first and last sentences of each paragraph. Teacher's Tip:"Read the article quickly, don't worry about new words. Focus on what each paragraph is mainly about." (Give students 1-2 minutes to finish the matching task.) 1.7.2013 词汇学习完毕,现在我们进入课文阅读。首先,我们来练习一种阅读技巧——略读(Skimming)。请大家快速阅读文章,不需要理解每个单词,重点是抓住每个段落的大意。然后将段落和右边的大意进行匹配。给大家1-2分钟时间。 ‹#› Facts about Qomolangma 喜马拉雅山脉(The Himalayas)是世界海拔最高的山脉,沿中国西南部绵延,其主峰珠穆朗玛峰(Qomolangma)是世界最高峰,也是登山爱好者心中的圣地。 01. 核心句型:One of the + 最高级 + 名词复数 用于表达“最……之一”,是描述事物特征的经典句式。如文中“One of the world's most dangerous sports is mountain climbing”,简洁有力地突出了登山运动的属性。 02. 重点短语:run along 意为“沿着……延伸”。可以把山脉想象成一条长长的丝带,蜿蜒铺展在地图上,生动体现山脉的走向。文中“The Himalayas run along the southwestern part of China”精准描绘了山脉的地理位置。 03. 课堂思考 观察地图,尝试用“run along”描述你熟悉的一条河流或道路;并用“One of the...”句型,介绍一个你喜欢的著名景点。 1.7.2013 我们来看第一段。这段介绍了喜马拉雅山脉和珠穆朗玛峰的基本情况。注意这个句型 One of the + 形容词最高级 + 名词复数,表示“最……之一”。还有一个短语 run along,意思是“沿着……延伸”。大家看这张地图,喜马拉雅山脉就是沿着中国的西南部延伸的。 ‹#› Grammar Focus - Expressing Height 01. 核心概念:描述地理与事物的度量 描述物体的高度、长度、宽度或深度是英语中描述地理事物的必备技能。它的本质是用具体的数字和单位来量化空间属性,让描述更精准、客观。 02. 易错辨析:High vs. Tall 形容山峰、建筑等非生物的高度用high;形容人、动物等有生命的个体身高用tall。例:He is two meters tall. / The mountain is high. 句型 A:Subject + be + Number + Unit + Adjective 结构简洁,适用于日常和书面表达。形容词随描述维度变化:high (高), long (长), wide (宽), deep (深)。 Example: Qomolangma is 8,844.43 meters high. 句型 B:Subject + be + Number + Unit + in + Noun 更正式的书面结构,名词形式与形容词对应:height (高度), length (长度), width (宽度), depth (深度)。 Example: Qomolangma is 8,844.43 meters in height. 课堂互动:How high is Qomolangma? 试着翻译:“这个湖深200米” (This lake is 200 meters deep.)。思考:描述河流长度应该用哪个词? 1.7.2013 这一页我们聚焦于英语中如何表达高度。首先,核心概念是用数字和单位来量化事物的空间属性,这在描述地理特征时非常重要。 大家要特别注意易错点:形容山峰、建筑等无生命物体的高度用 "high",而形容人或动物的身高用 "tall"。 我们有两个常用的句型:句型A比较简洁,直接用“主语+be+数字+单位+形容词”,比如珠峰的例子;句型B则更正式,用“in+名词”的结构,如“in height”。 最后,试着用我们学到的句型来回答底部的互动问题,巩固一下今天的知识点。 ‹#› Dangers of Climbing 高海拔的冰川峭壁环境恶劣,每一步攀登都面临着未知的风险,是对人类极限的终极考验。 01. Thick Clouds & Heavy Snowfall Thick clouds cover the top, obscuring the path, while heavy snowfall creates treacherous and unstable terrain for climbers. 02. Freezing Weather & Storms Extremely low temperatures and sudden heavy storms are constant threats, testing both physical endurance and equipment limits. 03. Severe Lack of Oxygen As altitude increases, the air becomes thin, making it extremely hard to breathe—a fatal hazard if not properly acclimatized. Class Interaction:Why is it hard to take in air near the top? Can you think of any other challenges climbers might face? 1.7.2013 第一段后半部分列举了攀登珠峰的种种危险。我们一起来总结一下:浓密的云层、大雪、极寒天气和暴风雪,以及最致命的——缺氧。这些都是登山者必须面对的巨大挑战。为什么山顶附近会呼吸困难呢? ‹#› Historical Achievements 1953 · The Pioneers Tenzing Norgay and Edmund Hillary became the first people to reach the summit of Qomolangma, marking a milestone in human exploration. 1960 & 1975 · New Heights The first Chinese team conquered the peak in 1960. In 1975, Junko Tabei from Japan became the first woman to succeed, breaking gender barriers. Key Pitfall: Date Confusion A common mistake is mixing up the years of different milestones. Remember to link each achievement to its specific time and group for clarity. The Big Picture: Human Progress These ascents are like technological breakthroughs—each step represents humanity’s collective courage to push boundaries and achieve the impossible. Class Discussion & Reflection Q: "Who were the first to reach the top?" / "When did the first Chinese team summit?" Share your thoughts on how these achievements inspire us today. 1.7.2013 第二段讲述了人类攀登珠峰的历史成就。我们来提取关键信息:1953年,丹增·诺尔盖和埃德蒙·希拉里首次登顶;1960年,中国登山队首次登顶;1975年,日本的田部井淳子成为首位登顶的女性。这些都是人类挑战极限的伟大时刻。 ‹#› Language Focus - 'the first to do sth.' 核心语法定义 结构“the first/second/last + to do sth.”用于描述动作或事件发生的顺序。不定式在此作后置定语,修饰前面的序数词,是一种正式且精确的表达,常用于叙述历史事件与成就。 场景例证解析 就像排队买票,“He was the first person to get the ticket.” 清晰表达顺序。再如:She was thelast student to leavethe classroom. / He was the second man to walk on the moon. 避坑指南 & 要点 易错点:极易漏掉不定式符号“to”。正确:the first to reach;错误:the first reach。此结构强调“动作的先后顺序”,不可省略to。 课堂互动:尝试用这个句型造句。例如:“Liu Xiang was the first Chinese man to win an Olympic gold medal in track and field.” (刘翔是首位获得奥运田径金牌的中国男子运动员。) 你能想到其他例子吗? 1.7.2013 第二段有一个重要的语言点:the first to do sth.,意思是“第一个做某事的人或物”。这里的不定式 to do sth 用来修饰前面的名词。比如课文中的 the first people to reach the top。大家能用这个句型造一个句子吗?比如,刘翔是第一个获得奥运会田径金牌的中国男子运动员。 ‹#› Paragraph 3: Why Do People Climb? "Why do so many climbers risk their lives? One of the main reasons is because people want to challenge themselves in the face of difficulties." 这是文章主旨的核心,引导我们从“攀登行为”的表象,深入探索人类直面困境、超越自我的精神内核。 01. Risk Their Lives 意为“冒生命危险”。登山者明知前路凶险,仍选择出发,体现了对极限的无畏探索。 02. Challenge Themselves 即“挑战自我”。这不仅是对体能的挑战,更是对意志力、恐惧和舒适区的全面突破。 03. In the Face of Difficulties 意为“面对困难”。强调在逆境和未知面前,依然保有直面问题、迎难而上的勇气。 ▌ 生活化共鸣:这正如我们攻克高难度的谜题游戏,并非为了最终的奖品,而是享受解开谜题那一刻的成就感,以及战胜内心恐惧与挫败感的纯粹喜悦。 ▌ 深度思考:“在困难面前挑战自我”对你来说意味着什么?是克服一次公开演讲的紧张,还是坚持完成一项艰难的学习任务? 1.7.2013 第三段提出了一个深刻的问题:为什么这么多人要冒着生命危险去攀登珠峰?文章给出的答案是:因为人们想在困难面前挑战自我。这正是文章的主旨所在。“在困难面前挑战自我”对你来说意味着什么? ‹#› 登山者的精神 攀登,不仅是对山峰的征服,更是对自我极限的挑战。每一步向上,都诠释着人类最宝贵的精神内核。 “The spirit of these climbers shows us that we should never give up trying to achieve our dreams.” 永不放弃 面对自然的伟力与未知的艰险,始终保持向前的勇气,不因困境而停滞脚步。 成就梦想 将宏大的目标分解为每一步切实的行动,在坚持中让梦想的轮廓逐渐清晰。 超越自然 人类的意志与智慧凝聚在一起,有时能迸发出比自然伟力更强大的力量。 📝 生活映射与思考:这精神并非遥不可及。当你绞尽脑汁攻克一道难题、克服学习中的倦怠时,你就是自己的“登山者”。试着回想:你曾在何时,感受到了“人定胜天”的力量? 1.7.2013 最后,文章升华了主题。登山者的精神告诉我们:永不放弃实现梦想,并且人类有时可以比自然的力量更强大。这种精神离我们并不遥远。当你克服学习中的一个困难时,你就体验到了这种精神。我们能从登山者的精神中学到什么? ‹#› Reading Task 2: Scanning 01. What is Scanning? It means reading quickly to locate specific pieces of information, such as names, dates, numbers, or key facts, without reading every word. Why It Matters It cultivates the ability to find information accurately and efficiently, which is essential for academic and daily life. Common Pitfall Students may struggle to find the exact sentence matching the question. Focus on keywords and context clues to narrow down the search. Analogy: Think of it like looking up a word in a dictionary or finding a show in a TV guide—you don’t read everything, just scan for what you need. Task 3c: Scan for Answers 1. Where are the Himalayas? They run along the southwestern part of China. 2. How high is Qomolangma? It is 8,844.43 meters high, the highest mountain in the world. 3. Why climb despite dangers? People want to challenge themselves in the face of difficulties and test their limits. 4. The spirit of climbers? It tells us that we should never give up trying to achieve our dreams. Class Activity:Now, work in pairs to scan the text and find the answers to these questions together. 1.7.2013 接下来,我们练习另一种阅读技巧——扫读(Scanning)。这次我们的目标是快速找到具体信息。请大家看屏幕上的这几个问题,快速在课文中找到答案。可以和同桌一起完成。 ‹#› Grammar Focus: Superlatives Definition & Example We use superlatives to compare one person or thing with all others in a specific group. It is the core grammar for describing "the best" or "the most" in the world. "Qomolangma rises the highest and is the most famous mountain in the world." Structure & Pitfalls Short Adjectives:the + adj. + -est e.g., high → the highest; fast → the fastest Long Adjectives:the + most + adj. e.g., famous → the most famous; interesting → the most interesting ⚠️ Don't forget "the"! Note irregular forms: good→best, bad→worst, far→farthest. Life Analogy It is just like selecting "the tallest boy", "the fastest girl" or "the most popular teacher" in your class—we pick the No.1 from a group! Think:What is the highest building in our city? Who is the most popular singer in your class? Class Activity:Work in pairs to make sentences using the superlative form of these words:fast, beautiful, interesting.Share your sentences with the class. 1.7.2013 现在我们来复习本单元的核心语法——形容词最高级。最高级用于在一个群体中进行比较。短形容词加-est,长形容词加most。注意,最高级前面通常要加the。我们城市最高的建筑是什么?你们班最受欢迎的歌手是谁? ‹#› Language Focus: Superlative in a Different Way 01. Core Concept & Definition We use comparative adjectives to express superlative meanings, emphasizing that something is the best or most extreme in a group. This structure translates to “比其他任何一个都……” in Chinese, making the statement more emphatic and advanced. 02. Sentence Transformation Qomolangma ishigher than any other mountainin the world. ↕ Equivalent meaning Qomolangma isthe highest mountainin the world. Key Point & Analogy Use "than any + singular noun" if the subjects are NOT in the same group. For example, "He is taller than any student in Class 2" implies he is not in Class 2. Class Practice Rewrite: "The Nile is the longest river in the world." (Answer: The Nile is longer than any other river in the world.) 1.7.2013 除了用最高级,我们还可以用比较级来表达最高级的含义。比如,“珠穆朗玛峰比世界上任何其他山峰都高”,这句话其实就等于“珠穆朗玛峰是世界上最高的山峰”。这是一种更强调的说法。大家试着用这个结构改写一下这个句子:“尼罗河是世界上最长的河流。” ‹#› Summary & Discussion 01. Core Concepts Definition:A summary is a concise statement of a text's main points, filtering out details. Key Focus:Avoid getting lost in minor details; capture the essence of the story. Analogy:Like retelling a movie plot to a friend—short, clear, and to the point. 02. Text Recap Subject:Qomolangma, the world's highest and most dangerous peak. Dangers:Thick clouds, blizzards, extreme cold, and oxygen deprivation. Spirit:The climbers' "never give up" attitude inspires us to chase dreams bravely. 03. Key Achievements 1953 Milestone:Sir Edmund Hillary and Tenzing Norgay became the first to reach the summit. Human Endeavor:Despite the risks, many climbers have followed, driven by curiosity and courage. Respect Nature:Climbing also teaches us humility and the need to protect our planet. Reflect & Share: What is the most important lesson you've learned from the climbers' stories? How can you apply this spirit in your own life? Debate & Discuss: If given a chance, would you attempt to climb Qomolangma? Why or why not? Discuss the balance between adventure and safety. 1.7.2013 好了,学完了整篇文章,我们来总结一下。这篇文章介绍了珠峰的危险、人类的攀登成就,以及最重要的——登山者永不放弃的精神。通过这篇文章,你学到了什么?如果有机会,你愿意去攀登珠峰吗?为什么? ‹#› Writing Task 01 / Core Mission Write a short paragraph about a personal challenge you have faced, applying the vocabulary and sentence patterns we've learned. Key Insight:Turn "input" (reading) into "output" (writing). It's like learning to cook a dish—now it's your turn to make it yourself! 1. Identify the Challenge What was it? (e.g., learning to ride a bike, passing a difficult exam, making new friends) 2. Describe the Difficulty What problems did you meet? (e.g., falling down many times, not understanding the questions) 3. How You Overcame It What actions did you take? (e.g., kept practicing, asked for help, studied hard) 4. The Lesson Learned What did you realize? (e.g., "I learned that I should never give up" or "Practice makes perfect") 1.7.2013 现在,我们来进行一个写作任务。请大家回忆一次你克服挑战的经历,可以是学习骑自行车,也可以是通过一场重要的考试。试着用我们今天学到的词汇和句型,写几句话来描述它。你可以参考屏幕上的提示。写完后,我们会请几位同学来分享。 ‹#› Homework 01. Review Review the new words and phrases from this lesson carefully. Make sure to memorize their pronunciations and usages. 02. Read Aloud Read the article (3a) aloud three times with correct intonation and rhythm. Pay attention to the stress of key sentences. 03. Writing Task Finish the writing task about your personal challenge. Describe the experience in detail and how you overcame it in your own words. 04. Preview Preview Section B before the next class.

Let us move forward with strong and active faith." “实现明天理想的唯一障碍是今天的疑虑。让我们怀着坚定而积极的信念,奋勇前进。” —— Franklin D. Roosevelt / 富兰克林·D·罗斯福 1.7.2013 最后,我想用罗斯福总统的一句话来结束今天的课程:“实现明天理想的唯一障碍是今天的疑虑。让我们怀着坚定而积极的信念,奋勇前进。” 希望大家都能像登山者一样,勇敢地挑战自我,永不放弃。下课! ‹#› $
