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

文章中多次使用 specific time markers 来说明婴儿 language development 的时间节点，比如 within the first month、six or seven weeks old、nine months 等。这些 precise numerical references 让读者清晰地看到婴儿在不同 developmental stages 的 speech perception abilities，强化了文章关于婴儿天生具备 language acquisition 能力的 main argument。通过 concrete numbers，作者避免了 vague descriptions，让 developmental timeline 变得 tangible and credible。

信号词 within by the time at only as young as first months weeks years

仿写： 在写作时，思考你的 topic 是否涉及 time、quantity、scale 或 measurement。比如描述 technological progress，你可以说 'Within the past decade, smartphone users increased from 1 billion to 6.8 billion'。模版：'[Time frame], [subject] [具体数字] → [another 具体数字]' 或 'By the time [time marker], [subject] can [action]'。关键是让数字服务于你的 central claim，而不是堆砌 statistics。

文章通过 concrete examples 来 illustrate 婴儿的 speech perception。比如 'They will stop crying when they hear a person talking, but not if they hear a bell ring' 这个 behavioral example 清晰展示了婴儿能 distinguish human voice from other sounds。这种 specific instance 让 abstract concept（婴儿对人声的 special attention）变得 vivid and observable，帮助读者 visualize 婴儿的 actual responses。

信号词 for example for instance such as when if merely observed

仿写： 寻找能够 represent 你观点的 typical scenarios。问自己：'What would this look like in practice?' 比如说明 AI impact on daily life，你可以写 'When you ask your phone a question, it responds instantly, but if you type random numbers, it remains silent'。模版：'[Subject] will [action A] when [condition X], but not if [condition Y]' 或 'For instance, [具体场景]'。关键是选择 relatable examples。

文章最后一段使用了 striking comparison：'language is a sensory-motor delight rather than the route to dull meaning that it often is for adults'。这个 adult-baby contrast 突出了婴儿 language experience 的独特性，强化了文章关于婴儿以 fundamentally different way 来 perceive speech 的 thesis。通过 juxtapose 婴儿的 joyful sensory experience 和成人的 meaning-focused approach，作者让读者 reconsider language acquisition 的 nature。

信号词 rather than unlike in contrast to while whereas but different from compared to

仿写： 识别你想 emphasize 的 quality，然后找一个 contrasting counterpart。使用 'rather than'、'unlike'、'while' 等 connectors。比如说明 children's creativity，你可以写 'For children, drawing is pure creative expression rather than the technical skill it becomes for trained artists'。模版：'For [Group A], [X] is [quality A] rather than [quality B] that it is for [Group B]'。

第二段明确提到 'One researcher observed' 和 'Other investigators have found'，这些 references to empirical studies 为文章提供了 scientific backing。虽然没有 cite specific names 或 publications，但 mentioning researchers' findings 增强了文章的 academic credibility，表明这些关于婴儿 language abilities 的 claims 不是 mere speculation，而是基于 systematic observations。

信号词 observed found researcher investigators studies show according to research indicates evidence suggests

仿写： 当你的 topic 涉及 scientific or factual claims 时，reference relevant studies 或 expert opinions。你不必 provide full citations，但要 acknowledge the source。比如 'Studies have shown that...' 或 'Researchers observed that...'。模版：'[Research entity] found/observed/discovered that [finding]' 或 'According to [source], [claim]'。关键是让 citation 自然融入你的 argument flow。

第三段的 'In other words' 是典型的 clarification marker，作者在这里 rephrase 前面的 observation，把 'response to general intonation' 这个 somewhat technical description 转化为更 accessible 的表达：'babies can make relatively fine distinctions between speech sounds'。这个 restatement 帮助读者 grasp 婴儿 perceptual abilities 的 precise nature，强化了文章关于婴儿天生具备 language discrimination 能力的 key point。

信号词 in other words that is that is to say put simply to put it another way namely i.e. meaning

仿写： 当你 introduce 一个 potentially confusing concept 后，用 'in other words'、'that is to say'、'put simply' 来 provide 一个 clearer version。问自己：'How else can I say this?' 比如 'Neural networks learn patterns. In other words, they identify recurring structures in data'。模版：'[Statement A]. In other words, [restatement B]' 或 '[Concept]. That is, [clarification]'。

文章在描述成人 speech adaptations 时 categorize different aspects：'simplified grammar, short sentences, and transformed certain sounds'，然后 'raise their volume, and speak slowly'，以及 'exaggerate their facial expressions, and emphasize certain words'。这种 systematic categorization 让读者清晰看到成人如何从 multiple dimensions（语法、语速、音量、表情）来 facilitate 婴儿的 language learning，supporting 文章关于成人本能地 simplify speech 的 argument。

信号词 such as including types of kinds of categories aspects dimensions on one hand...on the other

仿写： 当描述 multi-faceted phenomena 时，identify different dimensions 或 types。使用 parallel structures 来 list categories。比如说明 learning strategies：'Students employ cognitive tactics such as note-taking and summarizing, behavioral approaches like scheduled practice, and social methods including study groups'。模版：'[Subject] includes [Category A], [Category B], and [Category C]' 或按 aspects 分段 elaborate。
