第 4 步成果 · 逐题解题 + 防坑
21. What is an advantage of MacBike? [B. It offers many types of bikes]
解题：定位 Why MacBike 栏："We offer the newest bicycles in a wide variety, including basic bikes..., bikes with hand brake and gears..., bikes with child seats, and children's bikes"——基本款/手刹排挡款/儿童座椅款/儿童车，车型多样。
- 防踩坑 · 4 个错项逐个辨识
- AIt gives children a discount——原文只有"带儿童座椅的车"和"儿童车"，没有任何折扣字样，车型≠折扣
- B【正确答案】in a wide variety + 四种车型列举 = 车型多样
- CIt organizes free cycle tours——导览游要"buy your ticket... or book online"，是付费项目不是免费
- DIt has over 2,500 rental shops——数字张冠李戴：2,500 是自行车的数量，租车行只有 five rental shops（五家）
22. How much do you pay for renting a bike with hand brake and three gears for two days? [C. €22.75]
解题：两步取数：① 题干"hand brake and three gears"锁定表格左列（Hand Brake, Three Gears）；② "for two days" = 1 day (24 hours) €14.75 + Each additional day €8.00 = €22.75。
- 防踩坑 · 4 个错项逐个辨识
- A€15.75——用错列：Foot Brake 列 1 天 9.75 + 加 1 天 6.00 = 15.75，题干要的是手刹三排挡款
- B€19.50——用错列且重复首日：Foot Brake 列按两个"1 day"计 9.75×2 = 19.50
- C【正确答案】列对（14.75）+ 加对（8.00）= 22.75，"两天"=首日 + 1 个 additional day
- D€29.50——列对但重复首日：按两个"1 day"计 14.75×2 = 29.50，"每加一天"不是"每天都是首日价"
23. Where does the guided city tour start? [D. Dam Square]
解题：定位 Tours 栏："The tour departs from Dam Square every hour on the hour"——depart from = 从……出发 → 出发地 Dam Square。
- 防踩坑 · 4 个错项逐个辨识
- AThe Gooyer Windmill——是 tour "covers"（途经）的景点之一，不是出发地
- BThe Skinny Bridge——同为途经景点，玩的是"covers ≠ departs from"的文字差
- CHeineken Brewery——同上，途经≠出发
- D【正确答案】departs from Dam Square every hour on the hour = 出发地大坝广场

第 2 步成果 · 原文锚定
When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems.24 A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.24
After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.
The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.25 He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse-like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.26
"Ecological design" is the name John gives to what he does. "Life on Earth is kind of a box of spare parts for the inventor," he says. "You put organisms in new relationships and observe what's happening. Then you let these new systems develop their own ways to self-repair."27

原句（24 题锚定）：When he got older, John started to wonder if this process could be used to clean up the messes people were making.
枝叶（先砍掉）："When he got older"——when 时间从句；"if this process could be used to clean up..."——if 引导的宾语从句（wonder 的内容）；"the messes people were making"——省略 that 的定语从句，嵌在 if 从句之内（从句里再套从句，两层嵌套）
主干（砍完留的）：John started to wonder (about this).
推出：从童年"观察自然如何解决问题"到长大后"追问这个过程能否清理人类制造的烂摊子"——一路都是观察+提问 = inquiring mind（第 24 题答案的来源）。
第 4 步成果 · 逐题解题 + 防坑
24. What can we learn about John from the first two paragraphs? [C. He had an inquiring mind]
解题：两段的动作全是"观察 + 提问"：段 1 "loved to explore... observing how nature solved problems"、长大后 "started to wonder"；段 2 "went back to observing nature and asking questions. Why can certain plants...? Which kinds of fish...?"——一连串问句 = 好奇心、探究心。
- 防踩坑 · 4 个错项逐个辨识
- AHe was fond of traveling——他在"探索树林"（explore the woods），不是到处旅行
- BHe enjoyed being alone——没提他喜欢独处，说的是他爱观察提问
- C【正确答案】观察自然 + 连串提问 = inquiring mind（探究心）
- DHe longed to be a doctor——他只是"学过医学（medicine）"，没说渴望当医生，学科≠职业志向
25. Why did John put the sludge into the tanks? [D. To test the eco-machine]
解题：按段 3 的动作顺序读：先建 tanks → 放入动植物 → 等待"formed their own ecosystem"（生态成型）→ 然后才 "added the sludge" → 结果"took the sludge as food... all that was left was pure water"。污泥是待清除的有害物，加进去就是给这台已建成的机器上考题 = 检验。
- 防踩坑 · 4 个错项逐个辨识
- ATo feed the animals——"吃污泥"是加入后的意外结果，不是他的目的；他的任务本是"remove harmful substances from some sludge"
- BTo build an ecosystem——时间线错了：生态在加污泥之前就已"formed their own ecosystem"
- CTo protect the plants——文中没有"保护植物"的目的，恰恰是让动植物去消耗污泥
- D【正确答案】生态建成 → 加污泥 → 看结果（amazed at the results）= 检验 eco-machine
26. What is the author's purpose in mentioning Fuzhou? [B. To show an application of John's idea]
解题：看 Fuzhou 出现的位置：段 5 开头 "Over the years, John has taken on many big jobs"，先列 South Burlington 的 1,600 户污水设施，再列福州运河水治理——两个都是 eco-machine 落地应用的实例。
- 防踩坑 · 4 个错项逐个辨识
- ATo review John's research plans——福州是已建成的工程（designed），不是"回顾研究计划"
- B【正确答案】eco-machine 治理运河水 = 他的想法在中国东南城市的落地应用
- CTo compare John's different jobs——两个项目是并列举例，文中没有比较（孰优孰劣）
- DTo erase doubts about John's invention——全文没有任何"质疑者"，无从"消除怀疑"
27. What is the basis for John's work? [A. Nature can repair itself]
解题：锚定段 6 引语："You put organisms in new relationships and observe what's happening. Then you let these new systems develop their own ways to self-repair."——"让新系统自行修复" = 他工作的立足点：大自然能自我修复。
- 防踩坑 · 4 个错项逐个辨识
- A【正确答案】self-repair = 自然（新生态系统）可以自我修复
- BOrganisms need water to survive——生物需要水只是常识背景，不是他工作的"基础"
- CLife on Earth is diverse——引语说地球是"spare parts 的盒子"（零配件多），说的是可组合性，不是多样性本身
- DMost tiny creatures live in groups——"tiny creatures"只在段 1 出现过一次（溪流变清），无群居说法

The goal of this book is to make the case for digital minimalism, including a detailed exploration of what it asks and why it works, and then to teach you how to adopt this philosophy if you decide it's right for you.28
To do so, I divided the book into two parts. In part one, I describe the philosophical foundations of digital minimalism, starting with an examination of the forces that are making so many people's digital lives increasingly intolerable, before moving on to a detailed discussion of the digital minimalism philosophy.
Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter.29 This process requires you to step away from optional online activities for thirty days.29 At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.
In the final chapter of part one, I'll guide you through carrying out your own digital declutter. In doing so, I'll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter. You'll hear these participants' stories and learn what strategies worked well for them, and what traps they encountered that you should avoid.30
The second part of this book takes a closer look at some ideas that will help you cultivate (培养) a sustainable digital minimalism lifestyle. In these chapters, I examine issues such as the importance of solitude (独处) and the necessity of cultivating high-quality leisure to replace the time most now spend on mindless device use. Each chapter concludes with a collection of practices, which are designed to help you act on the big ideas of the chapter. You can view these practices as a toolbox meant to aid your efforts to build a minimalist lifestyle that works for your particular circumstances.31

原句（28 题锚定）：The goal of this book is to make the case for digital minimalism, including a detailed exploration of what it asks and why it works, and then to teach you how to adopt this philosophy if you decide it's right for you.
枝叶（先砍掉）："including a detailed exploration of what it asks and why it works"——including 短语，内含 what / why 并列宾语从句（详述"它要求什么、为何有效"）；"and then to teach you how to adopt this philosophy"——与 to make the case 并列的第二个目标，内含 how 宾语从句；"if you decide it's right for you"——if 条件从句（嵌在 how 从句后，两层嵌套）
主干（砍完留的）：The goal of this book is to make the case for digital minimalism and then to teach you.
推出：全书目标 = 论证"数字极简主义" + 教你采纳这种生活方式 → advocating a simple digital lifestyle（第 28 题答案的来源）。
原句（29 题锚定 · 句库精读句）：Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter.
框架：此句不足 20 词、四步法可跳过，但结构值得精读："concludes by introducing..."——by + 动名词交代"以什么方式收尾"；冒号后 "the digital declutter" 是 method 的同位语（给方法命名）。破题钥匙在下一句的定义："step away from optional online activities for thirty days"（远离可选线上活动 30 天）
主干（砍完留的）：Part one concludes by introducing my suggested method.
推出：declutter = 清空（可选线上活动）= Clear-up（第 29 题答案的来源；词义题的钥匙在"命名句 + 定义句"两连读）。
原句（29 题佐证句）：At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.
枝叶（先砍掉）："that you believe will provide massive benefits..."——that 定语从句修饰 activities，内嵌 "you believe"（believe 后省略 that 的插入从句，定语从句里再套从句，两层嵌套）；"the things (that) you value"——省略 that 的定语从句
主干（砍完留的）：You will then add back a small number of online activities.
推出：30 天"清空"之后才加回少量精选活动——先清后选，正是 declutter（清理）的完整流程（第 29 题的第二重证据）。
原句（30 题锚定）：In doing so, I'll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter.
枝叶（先砍掉）："In doing so"——介词短语（承上：指导你做 declutter 这件事）；"I ran in 2018"——省略 that 的定语从句修饰 experiment；"in which over 1,600 people agreed to perform..."——in which 定语从句（同样挂在 experiment 上，两处从句）
主干（砍完留的）：I'll draw on an experiment.
推出：末章素材 = 2018 年 1,600 人参与 declutter 的真实实验 → 下句 "You'll hear these participants' stories" = practical examples（第 30 题答案的来源）。
原句（30 题佐证句）：You'll hear these participants' stories and learn what strategies worked well for them, and what traps they encountered that you should avoid.
枝叶（先砍掉）："what strategies worked well for them"——what 宾语从句（学到什么）；"and what traps they encountered"——第二个 what 宾语从句，与上一个并列；"that you should avoid"——that 定语从句修饰 traps（嵌在第二个 what 从句内，两层嵌套）
主干（砍完留的）：You'll hear stories and learn what worked and what traps they encountered.
推出：听参与者讲"什么策略有效、什么坑要避"——全是第一手实例经验，坐实末章 = practical examples（第 30 题的双重证据）。
原句（31 题锚定 · 句库精读句）：In these chapters, I examine issues such as the importance of solitude (独处) and the necessity of cultivating high-quality leisure to replace the time most now spend on mindless device use.
框架：此句 31 词但只有一处省略 that 的定语从句（"the time most now spend"），按 AND 口径跳过、句库仍收录精读："such as A and B"——并列名词短语举例（独处的重要性 + 高质量休闲的必要性）；"to replace the time most now spend on..."——不定式表目的，内含省略定从（用高质量休闲替换"无意识刷手机"的时间）
主干（砍完留的）：I examine issues.
推出：part two 讲的是"可持续生活方式"的诸议题，每章末尾的 practices 是配套工具——所以下一句才说"当工具箱用、配合你自己的具体情况"（第 31 题答案 use them as needed 的来源）。
原句（篇结构语境句 · 句库精读句）：In part one, I describe the philosophical foundations of digital minimalism, starting with an examination of the forces that are making so many people's digital lives increasingly intolerable, before moving on to a detailed discussion of the digital minimalism philosophy.
框架：此句 40 词但仅有一处 that 定语从句（"the forces that are making..."），按 AND 口径跳过、句库仍收录精读："starting with... before moving on to..."——两个分词短语交代 part one 的展开顺序（先查"是什么把数字生活变得难以忍受"，再细讲哲学）；"philosophical foundations"——哲学基础
主干（砍完留的）：I describe the philosophical foundations of digital minimalism.
推出：part one = "为什么需要它"（哲学基础），part two = "怎么过日子"（可持续生活）——两部分的分工是全篇结构理解的底座，第 28 / 30 / 31 题都建立在这个分工上。

28. What is the book aimed at? [B. Advocating a simple digital lifestyle]
解题：抓首段目标句："The goal of this book is to make the case for digital minimalism... and then to teach you how to adopt this philosophy"——为数字极简主义辩护并教你采纳 → 提倡一种简单的数字生活方式。
- 防踩坑 · 4 个错项逐个辨识
- ATeaching critical thinking skills——书教的是"采纳数字极简"，不是批判性思维
- B【正确答案】make the case for digital minimalism = 提倡"少而精"的简单数字生活
- CSolving philosophical problems——"philosophical foundations"是第一部分的铺垫内容，不是要解决哲学问题
- DPromoting the use of a digital device——方向完全相反：全书是让你少用设备，不是推广设备
29. What does the underlined word "declutter" in paragraph 3 mean? [A. Clear-up]
解题：词义题的钥匙在"命名句 + 定义句"两连读：命名句 "my suggested method...: the digital declutter"，紧接着定义句 "This process requires you to step away from optional online activities for thirty days"——远离可选线上活动 = 把数字生活"清空"一下 = Clear-up。
- 防踩坑 · 4 个错项逐个辨识
- A【正确答案】step away from... for thirty days = 清空（清理）可选线上活动
- BAdd-on——恰是后段动作（30 天后才 add back 精选活动），那是 declutter 之后的步骤，不是它的词义
- CCheck-in——打卡签到，与"远离"无关
- DTake-over——接管，词形干扰（over 与 clutter 无关）
30. What is presented in the final chapter of part one? [C. Practical examples]
解题：定位段 4："In the final chapter of part one, I'll guide you through carrying out your own digital declutter. In doing so, I'll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter. You'll hear these participants' stories..."——末章素材是 1,600 人的真实经历。
- 防踩坑 · 4 个错项逐个辨识
- ATheoretical models——理论模型在哲学基础部分（part one 前段），末章是实操
- BStatistical methods——1,600 是参与人数，不是在讲统计方法
- C【正确答案】1,600 人实验 + participants' stories = 实践实例
- DHistorical analyses——2018 年的实验是当代经验，不是历史分析
31. What does the author suggest readers do with the practices offered in part two? [A. Use them as needed]
解题：锚定段 5 末句："You can view these practices as a toolbox meant to aid your efforts to build a minimalist lifestyle that works for your particular circumstances"——工具箱 + 配合你自己具体情况 = 按需取用。
- 防踩坑 · 4 个错项逐个辨识
- A【正确答案】toolbox + your particular circumstances = 按需使用
- BRecommend them to friends——原文是"自己用来搭建生活方式"，没有推荐给朋友
- CEvaluate their effects——没让你评估练习的效果，是"做"不是"评"
- DIdentify the ideas behind them——每章末 practices 本来就是"帮你 act on the big ideas"（落实大想法）的，想法已知无需再识别

第 2 步成果 · 原文锚定
On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the "wisdom of crowds" effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren't always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate.32 If people are similar and tend to make the same errors, then their errors won't cancel each other out. In more technical terms, the wisdom of crowds requires that people's estimates be independent. If for whatever reasons, people's errors become correlated or dependent, the accuracy of the estimate will go down.
But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals.33 For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.
In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds?34 This happened some of the time, but it wasn't the dominant response. Most frequently, the groups reported that they "shared arguments and reasoned together". Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.35

原句（首段语境句）：On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the "wisdom of crowds" effect.
枝叶（先砍掉）："On March 7, 1907"——时间状语；"which illustrated..."——which 定语从句修饰 paper；"what has come to be known as the 'wisdom of crowds' effect"——what 宾语从句，嵌在 which 从句之内（从句里再套从句，两层嵌套）
主干（砍完留的）：Francis Galton published a paper.
推出：1907 年 Galton 论文首次展示"群体智慧"效应——这是全文叙事的起点，后文段 2 讲它的原理、段 3 讲 Navajas 对它的"转折"。
原句（首段定义句）：The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
枝叶（先砍掉）："he conducted"——省略 that 的定语从句修饰 experiment；"that in some cases, the average... could be quite accurate"——that 宾语从句（showed 的内容），内含 in some cases 插入（两处从句）
主干（砍完留的）：The experiment showed that the average could be quite accurate.
推出："大量独立估计的平均可以相当准确" = 群体智慧效应的定义句，也是后文一切对比（独立 vs 分组讨论）的基准线。
原句（33 题锚定）：The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals.
枝叶（先砍掉）："that when crowds were further divided into smaller groups..., the averages..."——that 表语从句（finding 的内容）；"that were allowed to have a discussion"——that 定语从句修饰 smaller groups（嵌在表语从句内）；"than those from an equal number of independent individuals"——比较结构（those = the averages）
主干（砍完留的）：The key finding of the study was that the averages from these groups were more accurate.
推出：小组讨论 = 组内互相影响 → 估计"不再是完全独立"，但平均反而更准 → 即使 estimates were not fully independent，准确度也能升（第 33 题答案的来源）。
原句（33 题例证句 · 句库精读句）：For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.
框架：此句 27 词但无从句嵌套（分词后置 + 比较结构），按 AND 口径跳过、句库仍收录精读："obtained from the estimates of four discussion groups of five"——过去分词短语后置（4 个 5 人讨论组的估计所得平均）；"significantly more accurate than..."——比较级 + 程度副词
主干（砍完留的）：The average was significantly more accurate.
推出：4 组 × 5 人（讨论过）胜过 20 个独立个体——给第 33 题的发现配了一组具体数字。
原句（35 题锚定 · 句库精读句）：Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.
框架：此句 24 词、只有一处 although 让步从句，按 AND 口径跳过、句库仍收录精读："Although the studies led by Navajas have limitations and many questions remain"——让步从句（led by 分词修饰 studies，从句内两个并列分句）；"the potential implications... are enormous"——主句落点
主干（砍完留的）：The potential implications are enormous.
推出：先承认"有局限、问题仍多"（让步），再强调"对群体讨论与决策的潜在影响巨大"（落点）= approving 而非 doubtful（第 35 题答案的来源）。

第 4 步成果 · 逐题解题 + 防坑
32. What is paragraph 2 of the text mainly about? [B. The underlying logic of the effect]
解题：段 2 的推进全在讲"效应为什么成立"：误差不完全相同（有人高估、有人低估）→ 平均后 cancel each other out（互相抵消）→ 更准的估计；成立条件 = 估计必须独立（independent）。这就是效应背后的原理/逻辑。
- 防踩坑 · 4 个错项逐个辨识
- AThe methods of estimation——段 2 没讲"怎么估"的方法论，讲的是误差为何抵消
- B【正确答案】误差互抵 + 独立性条件 = 效应的内在逻辑
- CThe causes of people's errors——高估/低估是误差的两种方向，不是段落的重点（重点是"抵消"）
- DThe design of Galton's experiment——Galton 的实验在段 1，段 2 是原理阐释
33. Navajas' study found that the average accuracy could increase even if ________. [D. estimates were not fully independent]
解题：锚定关键发现句：crowds 分成小组、组内允许讨论后，小组的平均反而更准——讨论意味着组内的人互相影响，估计"不再是完全独立"（对照段 2 的独立性条件），但准确度反而上升。段 3 开头的 "an interesting twist（转折）" 正是提示：这个发现对"必须独立"的前提形成了反转。
- 防踩坑 · 4 个错项逐个辨识
- Athe crowds were relatively small——相反：效应的基石是"a large number"的平均，小群体不是本研究的发现
- Bthere were occasional underestimates——高估低估并存是段 2 的常态描述（互相抵消的来源），不是 Navajas 的新发现
- Cindividuals did not communicate——恰好相反：正是组内讨论过（沟通了）的组更准，C 与原文完全拧着
- D【正确答案】组内讨论 = 估计互相影响、不再完全独立，但平均更准
34. What did the follow-up study focus on? [C. The discussion process]
解题：定位段 4："the researchers tried to get a better sense of what the group members actually did in their discussion"——研究者自己抛出两个问句（"跟着最有信心的人走？""跟着最不肯改主意的人走？"），答案都不是主流；最常见的是 "shared arguments and reasoned together"。焦点 = 小组怎么讨论的。
- 防踩坑 · 4 个错项逐个辨识
- AThe size of the groups——100 名大学生、4 组×5 人等只是实验配置，不是研究焦点
- BThe dominant members——原文明确说"跟着最自信/最固执的人走"只 happened some of the time、wasn't the dominant response，被排除
- C【正确答案】"what the group members actually did in their discussion" = 讨论过程
- DThe individual estimates——后续研究看的是"组内怎么互动"，不是个人估计值本身
35. What is the author's attitude toward Navajas' studies? [D. Approving]
解题：锚定末句："Although the studies... have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous"——让步只占半句，落点词是 enormous（巨大的）。前文还铺垫了 "resulted in a global reduction in error"——全是正面评价信号。
- 防踩坑 · 4 个错项逐个辨识
- AUnclear——态度非常明确（enormous），不是含糊其辞
- BDismissive——没有"不屑一顾"，让步恰恰是"承认局限后仍然肯定"
- CDoubtful——"许多问题尚存"是客观陈述研究边界，主句落点是巨大潜力，不是怀疑
- D【正确答案】让步 + enormous + a global reduction in error = 赞许
