2024年12月英语六级真题第2套 Part II Section C (3)

作者用 "act like a time machine" 来形容 smell 的功能，将 scent 比作 time machine，生动地说明了 odor 能够 transport us back 到过去的 moment。这个 metaphor 为全文的 central thesis 奠定基础，instantly 让读者理解 olfactory memory 的 powerful nature，使抽象的 brain mechanism 变得 concrete and relatable。

信号词 like as similar to resemble act as serve as function as comparable to akin to

仿写： 在 explain 抽象的 mechanism 时，先问自己：这个 process 像什么？寻找 readers 熟悉的 everyday experience 来建立 connection。使用 "like" 或 "as" 来构建 simile，或直接用 "is" 构建 metaphor。模版："[主题] acts/works like [熟悉事物], [具体功能描述]" 或 "[主题] is [比喻对象] that [功能/特征]"。注意 comparison 必须 accurate 且 illuminating，不能 misleading。

文章在 opening sentence 用 "the delicious scent of bread" 作为 concrete example，让 abstract statement "sense of smell is powerful" 变得 tangible。这个 everyday example 能让 readers 立即 relate to 自己的 personal experience，为后续的 scientific explanation 建立 emotional foundation。Example 的选择非常 strategic，bread 的 scent 是 universally familiar 且带有 positive association。

信号词 for example for instance such as like including namely to illustrate as an illustration consider take one case is

仿写： 在提出 general statement 后，立即用 "for example" 或 "for instance" 引入 specific case。选择 examples 时要考虑 target audience 的 familiarity，优先选择 universal experience。模版："[总述观点]. For example/instance, [具体例子], [例子如何体现观点]"。可以在 paragraph 开头用 example 作为 hook，也可以在 explanation 后用 example 作为 reinforcement。

第2段 通过 process description 为 "scent" 下了 operational definition："a chemical particle that floats in through the nose"。这个 definition 不是 dictionary-style 的 static explanation，而是 dynamic 的，描述了 scent 从 physical particle 到 brain signal 的 transformation process。这种 definition 方式支持文章 main thesis，因为它 traces 了 pathway，解释了为什么 smell 和 memory 有 special connection。

信号词 is refers to means can be defined as is known as is called represents consists of involves describes

仿写： 在 introduce technical term 时，不要 assume readers' familiarity。使用 "is" 或 "refers to" 来建立 direct definition，或通过 describe 其 function/process 来 define。模版："[术语] is [类别] that [distinguishing features]" 或 "[术语] refers to [解释]"。对于 complex concepts，可以用 process description 来 define，说明 what it does 而不只是 what it is。确保 definition 与文章的 argumentative goal 对齐。

第3段 将 scent-triggered memories 与 sight or sound-triggered memories 进行对比，强调 "Scents are the only sensations that travel such a direct path"。这个 comparison 是文章的 argumentative core，通过 contrast 突出 olfactory system 的 uniqueness。"more emotional than" 这个 comparative structure 清晰地 establish 了 smell 的 superiority in evoking emotional memories，直接支撑 main thesis。

信号词 more...than less...than unlike in contrast to whereas while compared to rather than as opposed to different from similar to

仿写： 确定 comparison 的 purpose：是要 show superiority 还是 illustrate difference？使用 comparative adjectives（"more/less...than"）或 contrastive phrases（"unlike", "in contrast to"）。模版："Unlike [对象A], [对象B] [distinguishing feature]" 或 "[对象A] is more/less [特征] than [对象B], which [具体说明]"。确保 comparison 是 relevant 且 meaningful，serve 你的 argumentative goal。可以用 "while" 或 "whereas" 在一个 sentence 中建立 contrast。

第4段 用 "Imagine this scenario" 引入一个 hypothetical example：person walking down the street smelling a scent from decades ago。这个 extended example 用来 illustrate 为什么 memories 有时 don't surface despite emotional response。Example 的 narrative quality（"walking down the street"）让 abstract explanation about context 变得 vivid and comprehensible，帮助 readers visualize 这个 psychological phenomenon。

信号词 Imagine Consider Suppose Picture Think of Let's say For instance Take the case of In one scenario What if

仿写： 当 explain complex mechanism 时，create 一个 realistic scenario 让 readers 能够 mentally experience。用 "Imagine" 或 "Consider" 开头建立 hypothetical frame。模版："Imagine/Consider this scenario—[具体情境描述], which [如何体现要说明的原理]"。Scenario 应该包含 sensory details 和 sequential actions，让它 feel real。用 scenario 之后，explicitly connect back 到你的 theoretical point。

第4段 中 "The explanation is context" 后面的内容对 "baffling phenomenon"（emotional response without memory）进行 interpretation。作者 explain 为什么 different context 会让 memory retrieval 困难，clarifying "the brain uses the context to give meaning to the information"。这个 interpretation 不是 simple definition，而是 deeper analysis of mechanism，帮助 readers understand why context matters。

信号词 explanation reason because due to results from caused by stems from this occurs when this happens because accounts for

仿写： 在 present 一个 puzzling phenomenon 后，用 "The explanation is" 或 "This occurs because" 来 introduce interpretation。先 state the mechanism，然后 elaborate on how it works。模版："The explanation/reason is [核心机制]. [具体阐述如何运作]"。Interpretation 应该 move from general principle 到 specific application，showing readers not just what happens, but why it happens that way。

第5段 开头用 "notwithstanding" 转折，将 scent-triggered memories 与 "other memories" 进行 comparison，指出它们有 "same drawbacks"（不准确、会改变）。这个 comparison 平衡了全文对 olfactory memory 的 positive portrayal，showing 它们并非 superior in accuracy。"Even when they aren't" 的 contrast structure 强调了 perceived accuracy 和 actual accuracy 之间的 gap，为文章提供 nuanced conclusion。

信号词 same as like similar to also too as well likewise equally in the same way share have in common

仿写： 当需要 provide balanced view 或 acknowledge limitations 时，use comparative structure 来 show shared characteristics。"The same...as" 或 "like other" 可以 establish commonality。模版："Despite [特殊性], [主题] has/shares the same [特征] as [比较对象]" 或 "Like [其他事物], [主题] also [共同特点]"。这种 comparison 特别适合用在 conclusion 中，showing 你 understand the limits of your argument。
