2015年6月英语六级真题第3套 Part II Section C (2)

文章中多次引用了 Professor Seymour 的 direct quotes，比如 'In principle, you've got something which could be many times more effective than regular chemotherapy' 和 'There's an awful statistic of patients in the west…with malignant cancers; 75% of them go on to die from secondary cancers'。这些 expert quotes 为这个 innovative therapy 提供了 authoritative support，让读者感受到这不是 speculative reporting，而是有 scientific basis 的 breakthrough。通过 scientist's own words，文章成功地 convey 了这项技术的 revolutionary potential 和 clinical significance，同时也展现了研究者的 confidence 和 cautious optimism。

信号词 said according to stated explained noted commented remarked pointed out emphasized added

仿写： 在写作 scientific news 时，要善于识别哪些观点需要 expert endorsement。通常在介绍 new findings 或 making comparisons 时引入 direct quotes 最有效。选择引语时要注意它的 clarity 和 impact—好的引语应该既 informative 又 quotable。 仿写模版：According to [expert's name and title], "[direct quote presenting key finding or comparison]." This [innovation/discovery] could [explain its significance].

文章在 第6段 引用了一个 striking statistic：'75% of them go on to die from secondary cancers'。这个 concrete figure 不是随意提及，而是用来 illustrate the severity of secondary cancers 这个 clinical problem。数据的引入让抽象的 medical challenge 变得 tangible and urgent，强化了这项 virus therapy 的 practical value。配合 'awful statistic' 这样的 evaluative phrase，数据获得了更强的 emotional impact，帮助读者理解为什么 targeting secondary cancers 是如此 critical。

信号词 75% statistics study shows research indicates data reveals figures suggest according to studies X% of X in Y

仿写： 使用数据时要确保它 directly supports your main point。最有效的做法是在 presenting a problem 时用数据 quantify its severity，或在 describing a solution 时用数据 show its potential impact。数据前后要有 interpretative context—不要 drop numbers without explanation。 仿写模版：[Context-setting statement]. According to [source], [X%/X number] of [population] [experience specific outcome]. This [statistic/figure] highlights the [urgency/significance] of [the issue being discussed].

文章通过 multiple layers of contrast 来 highlight innovation。最明显的是 new virus therapy 与 traditional treatments 的对比：'avoiding some of the side-effects' 和 'many times more effective than regular chemotherapy'。还有 old approach（injecting viruses directly into tumours）与 Seymour's solution（masking viruses to spread through bloodstream）的对比。这种 systematic comparison 不仅 emphasize the novelty，更让读者清楚地 understand what makes this approach different and potentially superior。Through contrast，文章成功地 position 这项技术为 a significant advancement rather than just another incremental improvement。

信号词 while unlike in contrast to compared to rather than instead of whereas but however on the other hand more...than

仿写： 使用对比时要选择 meaningful dimensions—不要为对比而对比。最有效的对比通常 focus on key advantages：effectiveness, safety, applicability, 或 accessibility。使用 comparative language 比如 'while', 'unlike', 'in contrast to', 'more...than' 来 signal comparisons explicitly。 仿写模版：Unlike [conventional approach], which [limitation], this new [method/technology] [key advantage]. While traditional [X] can only [limited scope], the innovative approach [expanded capability].

文章采用了 neutral, factual tone 来 present scientific information，比如 'British scientists are preparing to launch trials' 和 'Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs'。这种 objective reporting style 通过使用 passive voice、factual verbs（'shows', 'indicates'）和 cautious language（'could', 'may', 'potentially'）来 maintain journalistic neutrality。即使在 discussing promising results 时，文章也 avoid sensationalism，而是 present findings in measured terms。这种 balanced approach 增强了报道的 credibility，让读者感到这是 reliable information 而非 hype。

信号词 shows indicates suggests demonstrates reveals found observed reported according to research study preliminary

仿写： 写作时要 distinguish between facts and interpretations。使用 'research shows', 'studies indicate', 'scientists found' 这类 attribution phrases 来 ground claims in evidence。采用 hedging language（'may', 'could', 'potentially', 'suggests'）来 reflect scientific uncertainty。Avoid emotional language 和 definitive claims when presenting early-stage research。 仿写模版：[Subject] is [action verb: developing/testing/investigating] [innovation]. [Evidence verb: Research shows/Studies indicate/Preliminary results suggest] that [finding]. This [could/may/might] [potential outcome], though [acknowledgment of limitations/need for further research].

文章在 第4段 通过 'Researchers have known for some time that viruses can kill tumour cells' 和 'American scientists have previously injected viruses directly into tumours' 来 provide historical context。这个 background information 不是 tangential—它 establish 当前研究的 context and lineage，让读者理解这不是 coming out of nowhere，而是 building on existing knowledge。通过 acknowledging previous work，文章也 set up the contrast that makes Seymour's approach novel（'but this technique will not work if...'）。这种 contextualization 帮助读者 appreciate the significance of the innovation within the broader research landscape。

信号词 previously for some time until now traditionally in the past historically earlier research prior studies have known have shown

仿写： 引入背景时要 selective—只包括 directly relevant 的信息来 frame current innovation。使用 time markers like 'previously', 'for some time', 'until now' 来 signal historical context。最有效的背景交代会 end with a limitation or gap that the current work addresses，创造 natural transition to the new development。 仿写模版：Researchers have [known/understood/attempted] [background information] for [time period]. Previous [studies/approaches/methods] [what was done], but [limitation]. This new [research/approach] [how it addresses the gap].

虽然文章没有使用 explicit questions，但 第5段 中的 'The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body's immune system destroying them on the way' 实际上是 addressing an implicit question：what was the main challenge? 这种 problem-framing 引导读者思考 why previous approaches failed，然后自然地 transition to Seymour's solution。通过 articulating the core challenge，文章创造了一种 intellectual suspense，让读者期待 how this obstacle was overcome。

信号词 hurdle challenge difficulty obstacle problem issue question the key has been how to whether

仿写： 使用 problem-framing 时要 identify the key obstacle that makes innovation necessary。可以用 'the challenge has been', 'the big hurdle', 'the main difficulty' 这类 phrases 来 explicitly state problems。最有效的是 present the problem immediately before introducing the solution，创造 problem-solution structure that is easy to follow。 仿写模版：The [main challenge/big hurdle/key difficulty] has been [articulate the problem]. [Researcher/team] has [developed/found/created] [solution] that [how it addresses the problem].
