Brain Scientists Identify a New Kind of Hunger that Makes Us Overeat

Imagine sitting down to a big dinner: a massive steak, a large portion of fried potatoes, and cake for dessert. After eating so much, you should be too full to eat another bite. But some people experience a powerful urge to keep eating, even after indulging in a huge meal, a behavior that makes little sense, as most adults are well-versed in the dangers of obesity, which researchers have shown correlates with innumerable health issues and is even linked to increased mortality risk. But some people still keep eating long after they should stop, a phenomenon Dr. Susan Thompson calls "insatiable(永不满足的) hunger." It is characterized by two main attributes: not being satisfied by eating, and having a desire to stay sedentary(久坐不动的).

This is at odds with how humans are biologically programmed. When there was a great deal of food available, ancient people would gorge on calories; this massive calorie intake was accompanied by an urge to get active. Humans were also programmed for something called "compensation," which is the brain's regulatory mechanism for preventing the accumulation of excess weight. With compensation, if you eat one large meal in the morning, you are naturally inclined to eat less for the rest of the day.

But recent studies show that 70% of American adults have lost the ability to naturally compensate for the calories they consume; worse still, a significant number of them report diminishing hunger halfway through an eating session, but, by the end of the meal, they feel the same or higher levels of hunger than when they sat down. Dr. Thompson argues that the main cause of this phenomenon is the modern diet, which is comprised of food high in sugar, carbohydrates and calories.

PARAGRAPHS · 逐段精读

3 段逐段主旨与解读

逐段拆解2023年6月英语六级真题第2套 的这篇原文——每段给出英文段落主旨、段落标题与中文解读，并提炼一条「这段为什么这样读」的具体方法。

  1. P1

    What Is Insatiable Hunger?

    The paragraph introduces and defines insatiable hunger as persistent eating without satisfaction and with sedentary desire.

    本段是全文的 problem introduction：它先提出一种看似不合常理的 eating behavior，再给它命名为 insatiable hunger。这个概念是后文 biological programming、compensation 以及 modern diet 解释的对象，因此本段为全文建立了明确的讨论中心。

    锁定定义句
  2. P2

    Humans' Natural Compensation Mechanism

    The paragraph explains the biological mechanisms that normally balance food intake and activity.

    本段承担全文的 benchmark function：它给出人类原本应有的 biological norm，即多吃之后会通过活动和少吃来调节。正因为存在这一正常参照，第三段中现代成年人失去 compensation ability 的问题才显得更严重，也使文章的因果解释更有逻辑基础。

    抓住补偿机制
  3. P3

    Modern Diet and Failed Compensation

    The paragraph reports the widespread loss of compensation and attributes it to the modern high-calorie diet.

    本段是全文的 evidence-and-cause conclusion：它用 70% 的研究数据证明问题具有 widespread scope，用饥饿感反常回升说明其具体表现，最后将 dysfunction 归因于 modern diet。至此，文章主旨形成完整闭环：先定义 insatiable hunger，再说明正常 compensation，最后揭示现代饮食如何导致该机制失灵。

SELF CHECK · 段落自检题

3 道逐段细节自检题

针对2023年6月英语六级真题第2套这篇原文，每段配 1 道细节题（ 1 个正确项 + 5 个干扰项 ，由懒笔记精读引擎基于本段命制，非试卷原题）。 选项默认中性；点「显示答案与解析」展开正确项、解析与最快解法，现代浏览器会同步高亮正确选项。

  1. 第 1 段 定位词 insatiable hunger

    What are the two identifying traits of "insatiable hunger" mentioned in the text?

    • A A sudden allergy to large portions of steak and fried potatoes.
    • B A genetic predisposition to enjoy high-calorie desserts.
    • C The lack of satiation after meals and a tendency toward physical inactivity.
    • D The immediate awareness of the health risks of obesity.
    • E An intense desire to exercise after overeating.
    • F A physiological need for more carbohydrates and sugar.
    显示答案与解析 收起答案与解析

    正确答案：C

    该选项将 not being satisfied by eating 改写为 lack of satiation，并将 desire to stay sedentary 改写为 tendency toward physical inactivity。两组表达形成 accurate paraphrase 准确同义改写，而且完整保留了原文的两个并列特征。

    并列双特征匹配 利用 keyword matching 关键词匹配，在 第1段 找到 quoted term 后，直接识别其附近的 parallel structure 并列结构，再检查正确项是否对两个并列成分都进行了语义对应，无需逐句通读整段。

  2. 第 2 段 定位词 compensation

    How does the biological mechanism of "compensation" work in humans?

    • A It encourages ancient people to store as much fat as possible.
    • B It triggers a desire to stay sedentary to save energy.
    • C It forces the body to burn calories immediately through exercise.
    • D It reduces appetite for later meals after a large intake of calories.
    • E It increases hunger levels in the morning to prepare for work.
    • F It speeds up the metabolism to prevent excess weight.
    显示答案与解析 收起答案与解析

    正确答案：D

    该项将 eat one large meal 与 eat less for the rest of the day 提炼为 general mechanism 一般机制，即较大的先期摄入会对应较少的后续进食。选项没有照抄例子，而是准确概括了 regulatory outcome 调节结果。

    条件链抽象匹配 在 第2段 找到 compensation 后，直接提取其 conditional example 条件例子中的前后变化，并将具体情景抽象为 intake-response pattern 摄入与反应模式。随后只需核对正确项是否保留这一变化关系，而不必逐一分析全部背景信息。

  3. 第 3 段 定位词 American adults

    What is the paradoxical finding about hunger reported by many American adults?

    • A They lose their appetite completely halfway through the meal.
    • B They prefer modern diets over traditional biological programming.
    • C They have gained a better ability to compensate for calories.
    • D Their hunger is primarily caused by a lack of carbohydrates.
    • E At the end of a meal, they feel as hungry as or hungrier than they did at the beginning.
    • F They are becoming more aware of their daily calorie intake.
    显示答案与解析 收起答案与解析

    正确答案：E

    该项完整保留了原文 same or higher levels of hunger 的两种可能，即饥饿程度与开始时相同或高于开始时。as hungry as or hungrier than 是准确的 comparative paraphrase 比较性改写，没有把原文范围缩窄为只有更饥饿一种情况。

    比较范围完整核对 先用 American adults 定位 第3段，再跳过背景解释，专门寻找包含 time comparison 时间比较和 hunger level 饥饿程度的句子。判定时采用范围审查法，优先检查正确项是否完整保留原文的并列可能性，避免被只保留其中一种情况的选项误导。

STRUCTURE · 篇章结构

3 个意群的说明文骨架

按说明文 的行文骨架切分意群，每个意群标注它覆盖的段落与对主旨的作用——逐段读完后回到这里俯瞰全篇，能看清作者为什么按这个顺序行文。

  1. P1

    提出现象：insatiable hunger的定义与特征

    这个意群通过一个生动的 scenario 引入了一个 paradoxical phenomenon——insatiable hunger，这种现象的核心是 people continue eating 即便在 huge meal 之后，并且明确指出这种 behavior 具有两个 main attributes：eating without satisfaction 和 desire to stay sedentary，这与 obesity risks 和 health issues 的常识形成 contradiction。

    作为 expository text 的 opening section，这个意群establish了需要解释的 central phenomenon，通过 concrete example（big dinner scenario）和 clear definition 来让读者理解什么是 insatiable hunger，为后续的 biological explanation 和 root cause analysis 奠定 foundation。

    描述现象本体
  2. P2

    对比解释：人类生物学正常机制

    这个意群通过 contrast 来 explain 为什么 insatiable hunger 是 abnormal，它描述了 humans 的 biological programming 应该如何 work：ancient people 在 abundant food 时会 gorge on calories 但同时有 urge to get active，更重要的是有 compensation mechanism 来 prevent excess weight accumulation，这种 natural regulatory system 使得 large meal 后会 naturally eat less。

    在 expository structure 中，这个意群提供了 normative baseline，通过 describing 正常的 biological mechanism 来 highlight 现代人 dysfunction 的 severity。这种 contrast strategy 是说明文常用的 explanatory technique，它让读者通过 comparison 更清晰地 understand 问题的 nature 和 magnitude。

    提供对照标准
  3. P3

    数据论证：现象普遍性与根本原因

    这个意群通过 statistical evidence 来 demonstrate 问题的 prevalence（70% of American adults）和 severity（lost ability to compensate，hunger increases during eating），然后 identify root cause——modern diet 中的 high sugar, carbohydrates and calories，这个 paragraph 从 quantitative data 出发最终 pinpoint 到 specific cause，完成了说明文的 causal explanation 核心任务。

    作为 expository text 的 concluding section，这个意群提供了 empirical evidence 来 quantify 问题的 scale，并完成最关键的 causal analysis，directly addressing 'insatiable hunger' 产生的 root cause。这种 data-driven explanation followed by cause identification 是说明文的 standard closing pattern，它给 entire explanation 提供了 concrete foundation 和 definitive answer。

    揭示问题根源
MAIN IDEA · 速判主旨

4 步定位这篇文章的主旨

不读完全篇也能锁定主旨——以下 4 步按2023年6月英语六级真题第2套 这篇原文的实际行文顺序给出，每步说明看哪里、看出什么，可直接迁移到其他英语六级文章。

  1. 首段核心现象定位 P1

    说明文的 primary purpose 是 explain 或 describe 某个 phenomenon，所以文章会在开篇 establish 要解释的 central topic，这是 thesis statement 的 foundation，抓住这个 key term 就能 anchor 整个 main idea

  2. 对比结构定位 P2

    说明文经常通过 contrasting 两个 states 或 conditions 来 clarify 问题的 abnormality 或 significance，这种 contrast 能帮助我们 understand 作者想 emphasize 的 problematic aspect，也就是 thesis 的 critical dimension

  3. 因果关系识别 P3

    说明文的 climax 通常是 causal analysis，因为 explaining causation 是说明文的 essential function。找到 'cause' 就找到了 author's explanatory focus，这是 thesis statement 的 conclusive element

  4. 三维整合综述 P1 P2 P3

    说明文的 main idea 是 multi-dimensional 的，需要 integrate 'what'（现象）、'how it differs'（对比）、'why it happens'（原因）这三个 components。Synthesizing 这些 elements 能 capture 作者的 complete explanatory intent，而不仅仅是 topic identification

主旨信号词 insatiable hunger P1 at odds with P2 main cause P3 70% P3 modern diet P3

MAIN IDEA · 主旨

这篇文章在说什么

这篇说明文解释了现代成年人"永不满足的饥饿"现象,将其与人类生物补偿机制进行对比。文章将这种功能失调归因于高糖、高碳水化合物和高热量的现代饮食,70%的美国人已丧失自然调节热量摄入的能力。
This expository text explains the phenomenon of 'insatiable hunger' in modern adults, contrasting it with humans' biological programming for compensation. It attributes this dysfunction—where 70% of Americans cannot naturally regulate calorie intake—to the modern diet high in sugar, carbohydrates, and calories.
WORD INFERENCE · 生词推断

4 个生词的上下文推断

不查词典，只用文中线索推出词义——每个词给出推断出的释义与 完整推理链。已收录进英语六级高频真题词集的单词可点击进入词条页。

  • indulge 纵情享受,放纵

    让我们把这些 clues 串联起来。首先，parallel structure 告诉我们 indulge 与 eating so much 在 semantic field 上重叠；然后，第2段 的 gorge 提供了一个 concrete behavioral reference，即 unrestrained consumption；最后，temporal logic 中的 even after 强化了 exceeding normal limits 这个 connotation。三条 evidence 共同指向一个 conclusion：indulge in 表达的是一种 allowing oneself to engage excessively，尤其是在 pleasurable activities like eating 方面。

    多层次推理三角验证法
  • gorge 狼吞虎咽,大吃大喝

    整合这些 threads：首先，cause-effect logic 配合 massive calorie intake 的 appositive 直接定义了 gorge 的 quantitative aspect；其次，anaphoric reference 消除了任何 ambiguity，确认 gorge = massive intake；最后，opposition with compensation mechanism 揭示了 gorge 的 qualitative nature——它是 excessive 到需要 regulatory response 的程度。三条 evidence 共同构建了一个 complete picture：gorge on 表示 eat excessively and greedily。

    衔接纽带追溯推断法
  • accumulation 积累,堆积

    让我们 synthesize 这些 insights。Morphological clues 提供了 structural foundation：repeated addition leading to increase；contextual clues from preventing 这个 verb 确立了 negative process 的性质；cross-paragraph inference 将这个 process 放入完整的 obesity development chain 中。三个 layers of evidence 共同指向：accumulation 是一个 gradual building-up process，在这个 context 中特指 excess weight progressively increasing over time。

    词法语境混合推理法
  • incline 倾向于,易于

    整合这些 analytical threads：naturally 这个 adverb 确立了 automatic, innate 的 nature；cross-paragraph contrast 显示 inclination 是可以 lost 的 regulatory capacity；sentence pattern analysis 将 incline 归入 tendency expressions。三条 evidence 共同描绘：be inclined to 表达一种 natural tendency or disposition to do something，在这个 biological context 中特指 innate regulatory response。

    模式识别归类推断法
RHETORIC · 修辞手法

6 处修辞手法与仿写

每处修辞给出它在本文的具体用法、同类信号词清单与一份可直接套用的 写作仿写建议——读完能认，也能写。

  • 举例子

    P1

    文章开头通过 a massive steak, a large portion of fried potatoes, and cake for dessert 这样的 concrete examples 让读者 visualize 一顿丰盛的 meal。这种 specific imagery 不是简单的 decoration，而是为了让 abstract concept 'insatiable hunger' 变得 tangible and relatable。通过 everyday food items 的罗列，读者能立刻 relate to 这种 eating scenario，从而更容易理解后面提到的 paradoxical behavior——明明 full 了还想继续 eat 的现象。这个 opening example 为整篇 text 的 main argument 奠定了 experiential foundation。

    信号词 for example for instance such as like including imagine consider suppose

    仿写： 当你需要 introduce 一个 abstract concept 时，问自己：What would this look like in real life? 比如讨论 procrastination 时，不要直接说 'people delay tasks'，而是 paint a picture：'a student staring at a blank document, refreshing social media every few minutes, making another cup of coffee'。仿写模版：Imagine [具体场景描述]: [具体例子1], [具体例子2], and [具体例子3]. 这种 opening pattern 能立刻 engage readers 并让 abstract topics 变得 relatable。

  • 列数字

    P3

    第三段中的 '70% of American adults' 和 'a significant number' 这些 quantitative data 为 argument 提供了 empirical weight。数字 70% 不仅 shocking，更重要的是它 transforms 'insatiable hunger' from an individual problem into a societal epidemic。这个 statistical evidence 让读者意识到这不是 isolated cases，而是 widespread phenomenon。通过 precise percentage，作者 establishes credibility 并 emphasizes the severity of the issue，强化了 modern diet 作为 root cause 的 argument。

    信号词 percent % studies show research indicates data reveals statistics demonstrate according to a significant number the majority of

    仿写： 使用数字时要考虑 strategic placement：在 introduce problem 或 support key claim 时插入。问自己：What can be measured here? 比如讨论 sleep deprivation 时，与其说 'many people don't sleep enough'，不如说 '35% of adults get less than 7 hours of sleep per night'。仿写模版：Recent studies show that [百分比/具体数字] of [群体] [动作/状态]; worse still, [另一个数字] report [更严重的情况]。注意用 'show that', 'report', 'indicate' 等 verbs 来 introduce statistics，增加 academic tone。

  • 下定义

    P1 P2

    文章中对 'insatiable hunger' 和 'compensation' 进行了 explicit definitions。第一段末尾，作者通过 'It is characterized by two main attributes' 来 define insatiable hunger，clarifying 它的 essential features：not being satisfied 和 desire to stay sedentary。第二段中 'compensation' 被定义为 'the brain's regulatory mechanism for preventing the accumulation of excess weight'。这些 precise definitions 是 expository writing 的 foundation，确保 readers 和 writer 在 same page。通过 clear definitions，作者 establishes terminology 并为后续 analysis 提供 conceptual framework。

    信号词 is defined as refers to is characterized by means is called is known as can be described as is a type of consists of

    仿写： 写 definition 时，使用 classic pattern：[Term] is/refers to/is characterized by [category] that [specific features]。避免 circular definitions（用词本身来 define）。要让 definition 既 precise 又 accessible，可以先给 general category，再提供 distinguishing characteristics。比如定义 'burnout' 时：'Burnout is a state of emotional and physical exhaustion that results from prolonged stress and is characterized by feelings of cynicism and reduced productivity.' 仿写模版：[术语] is/refers to [所属类别], which [核心特征/功能], and is characterized by [具体表现]。

  • 作比较

    P2

    第二段的核心是 contrast：ancient people 的 biological programming 与现代人的 dysfunction 形成鲜明对比。'This is at odds with' 这个 phrase 明确标示了 comparison。作者对比了 ancient eating patterns（gorge on calories → get active → natural compensation）和 modern patterns（eating without satisfaction → staying sedentary → no compensation）。这个 temporal comparison 不仅 highlights the problem，还 implies causation：modern lifestyle 背离了 biological design。通过 juxtapose past and present，作者让 readers 看到 deviation from natural state，为后文指出 modern diet 作为 culprit 做铺垫。

    信号词 in contrast however whereas unlike on the other hand conversely while but at odds with compared to

    仿写： 有效的 comparison 需要 clear points of contrast 和 parallel structure。使用 'while', 'whereas', 'in contrast', 'unlike' 等 contrastive markers。问自己：What two things reveal important differences when placed side by side? 比如讨论 traditional vs. modern education 时：'Traditional classrooms focused on memorization and lecture-based learning; in contrast, modern pedagogies emphasize critical thinking and interactive engagement.' 仿写模版：This is at odds with [参照对象]. When [情况A], [群体] would [行为1]; this [行为1] was accompanied by [行为2]. [群体] were also programmed for [机制], which [功能]. 这种 before-after 或 group A-group B 的 parallel structure 能清晰展现 contrasts。

  • 引资料

    P1 P3

    文章多次 cite expert opinion 和 research findings，最明显的是 'Dr. Susan Thompson calls', 'Dr. Thompson argues'，以及 'recent studies show'。这些 citations 为 arguments 提供 authoritative backing。通过 reference 专家和研究，作者将 personal claims 转化为 evidence-based assertions。特别是第三段的 'recent studies show that 70%...' 和 'Dr. Thompson argues'，这些 attributions 增强了 text 的 credibility，暗示这些 conclusions 不是 speculation，而是基于 scientific research。引用资料让 exposition 从 opinion 升级为 informed analysis。

    信号词 according to Dr./Professor [Name] argues studies show research indicates scientists report experts suggest data reveals calls claims states

    仿写： 引用时要自然地 integrate sources into your argument，不要让 citations 看起来 forced 或 disconnected。使用 reporting verbs ('argues', 'shows', 'demonstrates', 'calls', 'suggests') 来 introduce sources。问自己：Whose expertise would strengthen this claim? 比如讨论 climate change 时：'As leading climate scientist Dr. Smith argues, global temperatures have risen 1.2°C since pre-industrial times.' 或 'Recent NASA data shows that Arctic ice has decreased by 13% per decade.' 仿写模版：[专家/机构] calls/argues/shows that [观点/发现]. Recent studies/research indicate(s) that [数据/结论]. 注意 vary your attribution phrases 以避免 repetition。

  • 作诠释

    P1 P2

    第二段详细 explains compensation mechanism 的 workings：'if you eat one large meal in the morning, you are naturally inclined to eat less for the rest of the day.' 这不是简单的 definition，而是通过 concrete scenario 来 illustrate how the concept operates in practice。这种 elaboration 让 abstract biological process 变得 understandable。类似地，第一段解释 insatiable hunger 时，不只 define it，还 contextualizes 为什么这是 problematic（'makes little sense, as most adults are well-versed in the dangers of obesity'）。这些 interpretive passages 帮助 readers grasp not just 'what' but 'how' and 'why'。

    信号词 this means in other words that is to say which is to say if...then in practice what this means is to put it another way essentially

    仿写： 写 interpretive passages 时，ask yourself: How would this work in practice? What would it look like if...? 使用 conditional structures ('if X, then Y') 或 explanatory phrases ('this means', 'in other words', 'which is to say')。比如解释 'compound interest'：'With compound interest, your earnings generate additional earnings. If you invest $100 at 5% annually, you earn $5 the first year; the next year, you earn interest on $105, not just the original $100—meaning your wealth grows exponentially, not linearly.' 仿写模版：With [概念], [主要机制描述]. If [具体情况], [结果]; this [结果] [进一步解释/暗示]。关键是 move from general statement to specific illustration。

IMPLIED MEANING · 言外之意

3 处话里有话

作者没有明说、但靠信号词传递出来的态度与暗示——每处给出原文片段、信号词类型与解读。

  • 正常生理机制与异常行为的反差

    P1
    a behavior that makes little sense, as most adults are well-versed in the dangers of obesity

    评价性表达 makes little sense makes no sense doesn't make sense seems unreasonable appears illogical defies logic contradicts common sense

    这个 implied meaning 揭示了一个 paradox：人们明明 know the dangers（知道危险），却仍然 engage in harmful behavior（持续有害行为）。通过 makes little sense 这个 evaluative phrase，作者在 subtly emphasize 这个 phenomenon 的 severity 和 irrationality。对于 main thesis 的作用是：它为后续 explanation 奠定基础，暗示这不是简单的 lack of knowledge 问题，而是更深层的 biological or psychological mechanism 在起作用，从而 justify 为什么需要专门 term "insatiable hunger" 来描述这个 condition。

  • 古今生理机制的对比反差

    P2
    This is at odds with how humans are biologically programmed.

    对比类 at odds with in contrast to contrary to unlike differs from conflicts with contradicts

    这个 implied message 非常 critical：通过 at odds with 这个 contrastive phrase，作者在强调 modern eating behavior 不仅仅是个人 choice 的问题，而是已经 deviate from 人类的 biological design。言外之意是：这种 insatiable hunger 是 unnatural 的，是某种 external factor（后文会揭示是 modern diet）导致的 malfunction。对 main thesis 的贡献在于：它 establish 了一个 baseline——正常的 biological mechanism 应该是怎样的，从而为后续 explain 70% Americans 失去这个 mechanism 的 severity 提供 reference point。这个 contrast 让读者意识到问题的 magnitude。

  • 情况恶化的递进强调

    P3
    worse still, a significant number of them report diminishing hunger halfway through an eating session, but, by the end of the meal, they feel the same or higher levels of hunger

    递进类 worse still even worse more seriously more alarmingly what's worse to make matters worse worse yet

    这个 implied meaning 通过 worse still 传达了一个 alarming escalation：不仅人们失去了 compensation ability，更 troubling 的是他们的 hunger mechanism 已经 completely dysregulated——吃东西反而让 hunger increase。言外之意是这不是简单的 overeating 问题，而是 physiological system 的 profound disruption。对 main thesis 的 significance 在于：它 provide 最直接的 evidence 说明 modern diet 对人体的 impact 有多 severe，这种 counterintuitive phenomenon（吃得越多越饿）perfectly illustrates "insatiable hunger" 的 definition，也为文末 attribute 问题给 modern diet 提供 compelling support。

AUTHOR ATTITUDE · 作者态度

作者态度：消极批判

结论先行：本文作者态度为消极批判（ Concerned and explanatory）。下面是按步骤还原的判断过程与文中的态度信号词。

  1. 开头段的评价性表达 P1

    说明文的 opening 开头往往会 establish the tone 确立基调。这篇文章用 'makes little sense' 和 'should stop' 这样的表达，显示作者不是 neutral observation 中立观察，而是在 point out irrationality 指出不合理性。

  2. 正常与异常的对比 P2

    第二段用 'at odds with' 明确指出 current behavior 当前行为与 biological programming 生物本能相悖。这种 deviation from normal 偏离正常的对比，显示作者认为 current situation 当前情况是 problematic 有问题的。

  3. 数据的负面框架 P3

    第三段用 '70% of American adults have lost the ability' 和 'worse still' 这样的表达，不仅 present data 呈现数据，更是在 emphasize severity 强调严重性。数据本身是 neutral 中立的，但搭配 'lost' 和 'worse' 就显示出 concern 担忧。

  4. 问题归因表达 P3

    文章结尾用 'Dr. Thompson argues that the main cause' 来 pinpoint culprit 指出罪魁祸首——modern diet 现代饮食。这种 causal attribution 因果归因不是 neutral explanation 中立解释，而是在 assign blame 分配责任，显示作者的 critical stance 批判立场。

  5. 结构性态度累积 P1 P2 P3

    说明文的 neutral tone 中立基调会被 evaluative words、contrastive structures、negative framing 和 causal arguments 打破。这篇文章在每个 structural layer 结构层都嵌入了 critical signals 批判信号，显示作者的 attitude 态度是 consistently concerned 持续担忧的。

文中的态度信号词

  • makes little sense P1

    这个 phrase 短语直接 convey 传达作者认为这种 behavior 行为是 irrational 不合理的。在说明文中，如果作者使用 'makes little sense'，就已经跳出了 neutral description 中立描述，进入 critical evaluation 批判性评价。

    同类词 makes no sense is irrational is illogical defies logic is unreasonable

  • should P1

    Modal verb 情态动词 'should' 表达 expectation 期望和 obligation 义务。文中 'should be too full' 和 'should stop' 显示作者认为有一个 correct behavior 正确行为，而 current reality 当前现实 deviates from it 偏离了它，隐含 criticism 批判。

    同类词 ought to supposed to expected to is meant to need to

  • dangers P1

    Noun 名词 'dangers' 带有明显的 negative connotation 负面含义，显示作者在 highlight risks 强调风险。说明文用 danger-related vocabulary 危险相关词汇时，往往是在 warn readers 警告读者，显示 concerned attitude 担忧态度。

    同类词 risks hazards threats perils harms

  • at odds with P2

    这个 phrase 短语明确指出 contradiction 矛盾。作者用它来 emphasize 强调 current behavior 当前行为与 biological norm 生物规范的 mismatch 不匹配，显示这种 deviation 偏离是 problematic 有问题的。

    同类词 contradicts conflicts with is contrary to goes against is inconsistent with

  • worse still P3

    这个 intensifier 强化词显示作者在 escalate the severity 升级严重性。它不仅 present information 呈现信息，更是在 emphasize deterioration 强调恶化，显示作者的 deep concern 深度担忧。

    同类词 even worse more troubling more concerning what's worse to make matters worse

  • lost the ability P3

    这个 phrase 短语强调 loss of function 功能丧失，带有 negative connotation 负面含义。它显示作者认为 current state 当前状态是一种 deterioration 退化，而非 neutral change 中立变化。

    同类词 can no longer have ceased to are unable to lack the capacity fail to

  • argues P3

    Reporting verb 转述动词 'argues' 显示作者在 present a claim 呈现主张。它不同于 neutral 'says'，'argues' 隐含 there is a position to defend 有立场需要捍卫，显示作者 align with this argument 认同这个论证。

    同类词 claims contends asserts maintains posits

GENRE · 速判体裁

30 秒判定这是一篇说明文

体裁决定读法与出题套路。以下判断步骤与标志词全部以本文为例，可直接迁移到其他英语六级 真题文章。

如何快速判断这是一篇说明文？

  1. 开篇呈现现象 P1

    本文 第1段 直接 describe 了 'insatiable hunger' 这个 phenomenon,并通过 scenario (想象吃大餐) 来 illustrate。这不是在 argue 某个 viewpoint,也不是在 report 某个 news incident,而是在 explain 一个存在的现象。议论文会直接 state opinion,新闻报道会以 who/what/when/where 开头。

  2. 机制深度解释 P2

    第2段 详细 explain 了 biological mechanism (humans' programmed response 和 compensation),用 'this is at odds with' 来 contrast ancient 和 modern behavior。这是典型的 explanatory structure,在 clarify 背后的 principle。议论文会用这些 facts 来 support argument,新闻会简短 mention 而不会 deep dive into mechanism。

  3. 引证为解释服务 P3

    第3段 引用 'recent studies show' 和 'Dr. Thompson argues',但这些 citations 是为了 support 对 phenomenon 的 explanation (为什么会 lose compensation ability),而不是为了 win debate 或 confirm news authenticity。说明文的 evidence 服务于 clarification,议论文的 evidence 服务于 persuasion,新闻的 source 服务于 credibility。

  4. 教育性解释架构 P1 P2 P3

    本文 structure 清晰:第1段 introduce phenomenon,第2段 explain biological basis,第3段 provide research backing。整体 purpose 是 help readers understand 'insatiable hunger' 这个 concept,而不是 convince 他们 adopt certain behavior (议论文的 call to action) 或 update 他们 on breaking news (新闻的 timeliness)。缺少 opinion statement 和 news urgency,充满 educational intent。
