2016年12月英语四级真题第2套 Part II Section A (3)

文章开篇directly introduce了three university students和their location (Santiago, Chile)，以及他们develop的core invention，这种opening establishes了新闻的5W要素中的who、where和what。这个background setting为后续的detailed explanation做了铺垫，让readers能够immediately grasp文章的main subject，符合新闻报道中lead paragraph的写作原则，efficiently convey了最essential的information。

仿写： 写作news report时，可以adopt这种straight-to-the-point的opening方式。首先identify你要报道的core subject，然后在first sentence里combine关键要素。比如采用'数量+身份+地点+动作/成就'的structure。仿写模版：'[数字] + [身份名词] + in/at [地点] + have/has + [过去分词] + [核心成果/发明]'。Example: 'Five researchers at MIT have created a new material that...' 这样的opening immediately delivers核心信息。

文章用factual language描述了invention的working mechanism，解释plant在photosynthesis过程中produce energy，但only use a small part，而rest goes into the soil，E-Kaia正是collect这部分energy。这种objective description避免了subjective评价，instead focus on presenting how the device works through observable facts。这种neutral tone增强了news report的credibility，让readers能够form their own judgment based on facts而非作者的opinion。

信号词 process produces converts uses goes into collects captures

仿写： 实践objective description时，要consciously选择neutral verbs和factual nouns。Describe processes用'the device captures'、'energy goes into'这类observable actions，而不是'amazingly harvests'或'waste energy'。Focus on explaining mechanism through step-by-step logic。仿写模版：'[Subject] + [neutral verb] + [object/process] + explanatory clause describing observable result'。Example: 'The system collects heat that buildings generate during operation. This heat, which typically dissipates into the air, is redirected to...' 关键是让每个statement都base on observable facts。

文章provide了specific data point：'less than two hours'来quantify charging time。这个concrete number让abstract concept of efficiency变得tangible and comparable。Readers能够immediately understand device的practical value，因为他们可以relate这个timeframe to their own experience with phone charging。这种precision增强了report的credibility，同时也demonstrate了invention的practical applicability，支撑了文章关于这个device是viable solution的implicit claim。

信号词 less than within in under up to more than approximately nearly about over

仿写： Incorporate data时，要select那些most relevant and impressive的numbers。确保data point directly supports你的main message。Use precise expressions like 'less than X'、'within X minutes'、'up to X percent'。仿写模版：'The [device/system/method] + [action verb] + in/within [specific timeframe/quantity]'。Example: 'The filter purifies water in under 30 seconds' 或 'The algorithm reduces processing time by 40 percent'。Key是choose metrics that your target audience能够easily comprehend and relate to their experience。

文章quote了one of the inventors (Camila Rupcich)，她explain了device如何convert energy。这个direct quotation增加了authenticity，因为information来自firsthand source。引用inventor's words而非仅仅paraphrase，让readers feel closer to the actual people behind the innovation，增强了human interest element。同时，这个quote也serve as expert testimony，增强了technical explanation的authority，因为它comes directly from创造者themselves。

信号词 says explains notes states according to told commented mentioned added

仿写： 使用quotation时，要select那些add unique value的statements—那些explain complex concepts、reveal motivation或provide expert opinion的话。Introduce quote with attribution phrase identifying the speaker。仿写模版：'[Name/Title], says/explains/notes that [quoted statement]' 或 'According to [Name], "[direct quote]"'。Example: 'Lead researcher Sarah Chen explains that "the breakthrough came from observing natural processes."' 确保quoted material substantive enough to justify using direct speech而非paraphrase。一般来说，如果statement特别insightful或用unique wording表达key concept，就worth quoting directly。

文章implicitly contrast了plant produces的total energy和它actually uses的portion，指出'only a small part'被植物使用，'the rest'则进入soil。这个contrast突出了unused energy的存在，这正是E-Kaia innovation的foundation。通过highlighting这个gap between production和utilization，文章illustrate了为什么这个invention有value—它captures otherwise wasted resource。这种subtle comparison帮助readers understand the innovation's rationale without explicitly stating 'this is wasteful'。

信号词 only just while but however whereas in contrast the rest the remainder meanwhile

仿写： Deploy contrast时，要identify two related elements with meaningful difference。Use language that emphasizes the gap or distinction。仿写模版：'[Subject] + [verb] + only/just [small amount/portion], while/but [the rest/remainder] + [different fate/use]'。Example: 'Traditional systems capture only 30% of available heat, while the remaining 70% escapes unused' 或 'Current methods process just a fraction of the data, but the majority goes unanalyzed'。关键是让contrast serve a purpose—通常是highlight an inefficiency、opportunity或improvement。Avoid gratuitous comparison；确保contrast advances your narrative或supports your main point。

第四段reveal了invention的dual motivation：它既solved他们的class project requirement，又addressed他们的practical need for charging outlets。这个contextual information增加了story的human dimension，让readers understand that innovation不仅来自abstract research interest，还源于personal practical needs。这种background让invention feel more relatable和grounded in real-world circumstances，同时也subtly suggest了这个solution可能address broader charging accessibility issues。

信号词 solves addresses came from originated was inspired by emerged from grew out of stemmed from

仿写： 当providing mid-article background时，要focus on revealing motivations或circumstances that add meaning to your main subject。Structure应该connect back to previously mentioned elements。仿写模版：'The [invention/solution/initiative] + solves/addresses + [number] problems for [the creators]. They needed [reason 1]. They also needed [reason 2]'。Example: 'The app addresses two challenges for the research team. They needed a way to collect data remotely. They also needed to engage participants consistently'。这种pattern works well because它simultaneously explains practical value和personal motivation，creating richer narrative without departing from factual reporting。
