皓宇同学的课程学习报告

引入：共享经济主题

课堂推进：老师带皓宇进入“sharing economy（共享经济）”文章，先逐句讲解第1段核心概念：人们不再购买拥有商品或服务，而是借助数字平台租借、分享或借用。

老师处理：讲解 sharing economy 定义，解释 instead of / products / services / digital platforms / rent / share / borrow，并用网易云音乐和共享单车举例。

学生原始输出：In recently, a new economy model called sharing economy has grown rapidly around the world. Instead of only productive services, people use digital platforms to rent, share, to borrow them from others. Popular example including ride sharing apps and a website that allow home owner to rent out spare room to travelers.

复习抓手：sharing economy = 共享经济；product = 产品，service = 服务；rent / share / borrow = 租借、分享、借用；ride sharing apps = 滴滴打车这类共享出行应用

讲解：共享经济兴起的原因

课堂推进：老师讲解 three factors 段落：智能手机技术让供需双方对接、年轻人更看重使用权而非所有权、共享经济对环境更友好。

老师处理：解释 smartphone technologies / connect people who have something to offer with those who need it / prefer access over ownership / maintenance / parking costs / environmentally friendly / manufactured。

学生原始输出：Several factors driven this trend. First smartphone technologies makes it easy to connect people who have something to offer with those who need. Second, many consumer, especially younger ones, prefer access over ownership. They would rather pay to use a car for an hour than buy one and deal with maintenance and parking costs. So the sharing economy can be more environmentally friendly since fewer products need to be manufactured than existing ones are shared.

老师示范 / 修改方向：示范完整原文并纠正语法：First, smartphone technology makes it easy to connect people who have something to offer with those who need it. Second, many consumers, especially younger ones, prefer access over ownership. They would rather pay to use a car for an hour than buy one and deal with maintenance and parking costs. Third, the sharing economy can be more environmentally friendly since fewer products need to be manufactured when existing ones are shared.

复习抓手：smartphone technology 让供需双方 connect；prefer access over ownership = 宁要使用权不要所有权；maintenance = 保养，parking costs = 停车费；environmentally friendly = 更环保

讲解：共享经济的担忧

课堂推进：老师讲解 however 转折段：共享经济引发担忧，包括传统行业竞争不公、劳动者缺少福利、工作不稳定等。

老师处理：解释 concerns / traditional businesses / competition / regulations / lack benefits / health insurance / paid time off / unstable working conditions。

学生原始输出：However, the sharing economy also risks concert traditional businesses such as hotels and taxi companies. Face increased competition from individuals who may not follow the same regular. The workers in the sharing economy offer like benefits like health insurance and paid time off. Critics argue that while these platforms create convenience for users, they can also lead to unstable working conditions.

老师示范 / 修改方向：示范原文：However, the sharing economy also raises concerns. Traditional businesses such as hotels and taxi companies face increasing competition from individuals who may not follow the same regulations. Workers in the sharing economy often lack benefits such as health insurance and paid time off. Critics argue that while these platforms create convenience for users, they also lead to unstable working conditions.

复习抓手：raises concerns = 引发担忧；regulations = 法律规定/规范；lack benefits = 缺少福利；health insurance = 医保，paid time off = 带薪假期；unstable working conditions = 工作不稳定

练习与讲评：共享经济 5 道阅读理解题

课堂推进：皓宇先独立选出答案，老师逐题带他分析选项、排除干扰项，并强调“绝对词”陷阱。

老师处理：让学生先选答案；逐题讲解主旨题、细节题、词汇题、concern 题和作者态度题，纠正并确认答案。

学生原始输出：第1题选 B；第2题选 D；第3题 regulation 选 A（official rules）；第4题 D 选不出来，先蒙一个；第5题没选。

老师示范 / 修改方向：第1题主旨选 B：using digital platforms to rent or share goods and services；第2题选 D（与原文 prefer access over ownership 一致）；第3题 regulation = official rules；第4题选 C（workers lack benefits / unstable working conditions）；第5题选 D（author presents both benefits and concerns in a balanced way）。老师特别提示绝对词如 absolutely no value、completely neutral、no criticism 要排除。

复习抓手：主旨题抓住全文核心：共享经济是什么；细节题回原文找 prefer access over ownership；词汇题 regulation = official rules；绝对词选项（absolutely、completely、no longer expanding at all）通常不选；作者态度题要兼顾好处与担忧

进入第二篇：火山如何塑造地球表面

课堂推进：老师引入新文章 How volcanoes shape Earth's surface，逐句讲解火山喷发释放 lava（岩浆）、ash（火山灰）和 gases（气体），并长期塑造周围地貌。

老师处理：讲解 volcano / erupt / lava / ash / gases / deep within the planet / shape the landscape。

学生原始输出：volcano most the most powerful thing on Earth when a volcano erupts it releases the hot liquid rock called lava，along with ash and gases from deep within the planet over time these eruptions play a major role in shaping the landscape around them

老师示范 / 修改方向：示范原文：Volcanoes are among the most powerful forces on Earth. When a volcano erupts, it releases hot liquid rock called lava, along with ash and gases from deep within the planet. Over time, these eruptions play a major role in shaping the landscape around them.

复习抓手：volcano = 火山，erupt = 喷发；lava = 岩浆；ash = 火山灰/尘埃，gases = 气体；shape the landscape = 塑造地貌

讲解：火山创造新陆地

课堂推进：老师讲解火山活动最直观的影响：岩浆入海冷却后形成岩石，反复喷发可造岛；陆地上则形成锥形山。以夏威夷群岛为例。

老师处理：解释 visible effect / creation of new land / cools and hardens / solid rock / repeated eruptions / Hawaiian Islands / volcanic eruption on the ocean floor / cone shaped mountains。

学生原始输出：well the most visible effect of volcano activity the creation of the new land when lava flow into ocean it cools and hardens into solid rock，over several years repeated eruption can build entire island，the lava island for instance were formed entirely by volcanic eruption on the ocean floor，one land and lava on the cold lava and ash can build tall cone shaped mountains

老师示范 / 修改方向：示范原文：One of the most visible effects of volcano activity is the creation of new land. When lava flows into the ocean, it cools and hardens into solid rock. Over thousands of years, repeated eruptions can build entire islands. The Hawaiian Islands, for instance, were formed entirely by volcanic eruptions on the ocean floor. On land, layers of cooled lava and ash can build tall cone-shaped mountains.

复习抓手：visible effect = 可见的影响；creation of new land = 创造新陆地；cool and harden into solid rock = 冷却凝固成岩石；Hawaiian Islands = 夏威夷群岛，由海底火山喷发形成；cone-shaped mountains = 锥形山

讲解：火山对土壤的影响

课堂推进：老师讲解火山灰富含矿物质，使土壤肥沃，适合种植，因此人们历史上愿意住在活火山附近。

老师处理：解释 volcanic ash / minerals / potassium / sulfur（老师口误为 sulfurous）/ essential for plant growth / fertile farmland / active volcanoes / despite the obvious dangers。

学生原始输出：volcano also affect the soil，volcano ash contain materials such as potassium and the javan which are essential for planet growth，region near volcanoes often have extremely fertile farmland，this is one reason why people have lived near active volcanoes throughout history

老师示范 / 修改方向：示范原文：Volcanoes can also affect the soil. Volcanic ash contains minerals such as potassium and sulfur, which are essential for plant growth. Regions near volcanoes often have extremely fertile farmland. This is one reason why people have lived near active volcanoes throughout history, despite the obvious dangers.

复习抓手：volcanic ash = 火山灰；minerals = 矿物质；potassium = 钾，sulfur = 硫；essential for plant growth = 对植物生长至关重要；fertile farmland = 肥沃农田

讲解：火山喷发的破坏性

课堂推进：老师讲解火山喷发也有破坏性：掩埋城镇、摧毁森林、释放遮挡阳光的颗粒物，进而影响全球气候。科学家持续监测以预测喷发、保护社区。

老师处理：解释 disruptive / bury entire towns under ash / destroy forests / affect global weather patterns / releasing particles / block sunlight / monitor active volcanoes / predict eruptions / protect nearby communities。

学生原始输出：（本段主要由老师讲解，学生未朗读）

老师示范 / 修改方向：示范原文：However, volcanic eruptions can also be disruptive. Large eruptions can bury entire towns under ash, destroy forests and even affect global weather patterns by releasing particles into the atmosphere that block sunlight. Scientists continue to monitor active volcanoes closely, hoping to predict eruptions and protect nearby communities.

复习抓手：disruptive = 具有破坏性的；bury entire towns under ash = 把整座城镇埋在火山灰下；global weather patterns = 全球气候模式；release particles into the atmosphere = 向大气释放颗粒物；block sunlight = 遮挡阳光；monitor active volcanoes = 监测活火山

练习与讲评：火山阅读理解题

课堂推进：老师带皓宇完成火山文章阅读理解题，逐题确认答案并解释排除理由。

老师处理：引导学生做题；逐题分析主旨、夏威夷群岛成因、fertile 词义、人类居住原因、全球气候影响。

学生原始输出：（学生已提前或课堂中完成选择；老师讲解时确认学生答案基本正确）

老师示范 / 修改方向：第1题主旨选 A：how volcanic activity shapes landscape and affect the environment；第2题夏威夷群岛选 A：by building up rocks from the ocean floor；第3题 fertile = rich and good for growing plants；第4题选 B：because the soil near volcanoes is very good for farming；第5题选 B：by releasing particles into the atmosphere that block sunlight。

复习抓手：主旨题要覆盖全文：地貌+环境；细节题回原文找 Hawaiian Islands / formed by volcanic eruption on the ocean floor；fertile = 肥沃的，适合种植；绝对词 every single region 要排除

课堂收尾与作业布置

课堂推进：课堂最后 8 分钟，老师提醒皓宇完成之前答应但未做的第二篇与第三篇之间练习，并要求他打开屏幕共享现场完成。

老师处理：催促学生完成答应未做的练习；让学生打开屏幕共享；要求 8 分钟内做完。

学生原始输出：好的我刚没找到。好的听话，我自己去做。OK你答应我了啊。

复习抓手：课后需补齐第二篇与第三篇之间的练习
