2015年6月英语六级真题第1套 Part III Section C (2)

作者使用 public parks becoming crowded when the sun shines 这个具体的 observable phenomenon 来论证人们对 clean air 和 green spaces 的 longing。这个 concrete example 让抽象的 air pollution problem 变得 tangible and relatable，帮助读者理解 air quality 对 human behavior 的 direct impact。通过展示人们在公园里的 peaceful state，作者暗示了 breathable air 与 human harmony 之间的 connection，为后文关于 sharing air 而非 struggling 的 central argument 奠定基础。

信号词 The fact that For example For instance Consider the case of Take... as an example A case in point is This is evident in We can see this in

仿写： 当你想论证某个 abstract concept 时，问自己：有什么 everyday scene 可以让读者 immediately relate？比如论证 technology addiction，可以写 'The fact that restaurant tables fall silent as diners scroll through phones proves...'。模版结构是：'The fact that [observable phenomenon] proves/shows/demonstrates that [your claim]'。关键是选择 universally recognizable 的场景，让读者产生 'I've seen that too' 的共鸣。

作者在第三段建立了 clear causal chain：'If we lack the air necessary for a healthy life, it is because we have filled it with chemicals and undercut the ability of plants to regenerate it'。这个 if-because structure 直接点明了 air pollution 的 root cause，将 consequence（air shortage）和 human actions（chemical pollution + deforestation）紧密联系。这种 explicit causality 强化了文章的 central argument：人类必须改变对 natural resources 的 exploitative relationship。因果论证让 environmental crisis 不再是 abstract threat，而是 traceable to specific human behaviors。

信号词 because since as due to owing to results from is caused by leads to consequently therefore thus hence

仿写： 构建因果论证时，先明确 effect（你想解释的现象），再追溯 cause（导致它的因素）。使用 'If X, it is because Y' 或 'X results from Y' 结构。比如：'If students struggle with critical thinking, it is because education systems prioritize memorization over analysis'。重点是确保 cause and effect 之间有 logical necessity，避免 correlation 被误认为 causation。可以加入 supporting evidence 来 strengthen the causal link。

第四段使用鲜明的 contrast：'sharing life expands and enhances the sphere of the living, while dividing life into so-called natural or human resources diminishes it'。这个 while 连接的 binary opposition 将两种 worldviews 的 consequences 并置：sharing 带来 expansion and enhancement，dividing 导致 diminishment。这种 stark juxtaposition 迫使读者在两个 mutually exclusive paths 中做出 moral choice，强化了文章关于 rethinking human-nature relationship 的 urgent call。对比让 preferred approach（sharing）的 superiority 变得 self-evident。

信号词 while whereas in contrast on the other hand however conversely unlike rather than instead of but

仿写： 构建对比时，选择两个 fundamentally different approaches 或 outcomes，用 parallel structures 呈现。比如：'Traditional education emphasizes conformity, while progressive education cultivates creativity'。使用 'while', 'whereas', 'in contrast' 等 connectors。确保对比的两方面 address the same dimension（比如都讲 outcomes 或都讲 methods），形成 symmetrical opposition。可以用 verb choices 强化对比（expand vs. diminish, enhance vs. reduce）。

作者使用 'the lungs of the planet' 来描述 woods，这个 powerful metaphor 将 complex ecological function 转化为 easily understood human body analogy。通过将森林比作肺，作者让读者 immediately grasp 植物与人类呼吸的 vital connection。这个 figurative language 不仅 simplifies scientific concept，还 evokes emotional response：正如人类依赖肺 survive，地球同样依赖森林。比喻在此处 elevates 环保议题的 urgency，使抽象的 'oxygen production' 变成 visceral 的生存需求。

信号词 is are like as resembles serves as acts as functions as

仿写： 选择比喻时，找一个读者 universally understand 的 source domain（如人体器官、日常物品）来 represent target concept。结构通常是 'X is the Y of Z'。比如：'Social media is the fast food of information'。确保 comparison 有 meaningful parallels（肺和森林都关乎 breathing/air）而非 superficial similarity。可以 develop the metaphor by exploring shared characteristics（forests 'breathe' for the planet as lungs do for humans）。避免 mixed metaphors 和 clichés。

第二段的 'But is our life worth anything other than money?' 是 powerful rhetorical question，它不期待 direct answer，而是通过 questioning form 强制读者 confront 一个 uncomfortable truth。这个问题 challenges 当前 economic-centric value system，暗示 obvious answer（life is worth more）与 current practices（wealthy countries can pay to pollute）的 stark contradiction。反问在此处 serves dual purpose：critique existing policies 和 redirect readers' value orientation toward life preservation over economic gain。

信号词 Is Are Can Could Should Would Do we really How can What else Who would

仿写： 构建反问时，先确定你想 assert 的 statement，然后将它转化为 question form whose answer is obvious。比如 statement 'Education should prioritize creativity' 变为 'Can we truly prepare students for an uncertain future by teaching them only to memorize?'。使用 'Is/Are/Can/Should' 开头，确保 question 引导向 single, clear answer。Tone 应该 carry conviction，让 intended answer 显而易见。反问常放在 argument 的 turning points 以 strengthen emotional appeal。

第一段末尾建立了 subtle analogy：人们在 gardens 中 peaceful and peaceable 的状态，暗示了如果人类能 breathe and share air，就不需要 struggle with one another。这里将 physical space（gardens）的 harmony analogize to potential social harmony through shared air。作者通过 observable pattern in parks 来 suggest 更广泛的 social principle：access to shared resources（clean air）减少 conflict。这个 analogy 为后文关于 sharing life 的 ethical argument 提供了 experiential foundation。

信号词 just as similarly likewise in the same way analogous to comparable to parallel to like

仿写： 构建类比时，识别 source domain（熟悉的情况）和 target domain（你想论证的情况）之间的 structural parallels。比如：'Just as a garden thrives with diverse plants, a society flourishes with diverse perspectives'。Structure 通常是 'Just as X does Y, Z does W'。确保 mapping is meaningful：关键 relationships and patterns 在两个 domains 中 correspond。可以先 describe source case，再 draw parallel to target case。避免 over-extension：不是所有 aspects 都要对应，只需 relevant features align。

第四段末尾使用 parallel structure：'each takes it upon herself or himself and only when it is accomplished together with others'。这种 'only when X and only when Y' 的 repetitive pattern 创造了 rhythmic emphasis，强调 individual responsibility 和 collective action 的 dual necessity。排比通过 structural repetition 让 key message 更 memorable and forceful。这个 parallelism 也呼应了文章的 central theme：个人与集体、人类与自然的 interconnectedness，form and content 完美统一。

信号词 only when not only...but also both...and either...or neither...nor whether...or first...second...third

仿写： 构建排比时，选择 two or more related ideas 用 identical or similar grammatical structures 表达。比如：'We must protect the forests, preserve the oceans, and restore the soil'。确保 parallel elements 在 grammar（都是动词短语）、length（roughly equal），和 importance（equally significant）上 balanced。可以使用 repeated openings（'only when X, only when Y'）或 consistent patterns（verb + object）。排比常用于 conclusions or key points 以 leave strong impression。Aim for three elements（tricolon）for optimal rhetorical effect。
