年考研英语完形填空选自《自然》杂志相关主题文章,全文约350词,分为三段式结构:
• 第一段(引言段):以人工智能发展现状切入,点明技术革新带来的双重效应;
• 第二段(核心段):聚焦AI在环境保护中的具体应用与现实瓶颈;
• 第三段(结论段):提出技术应用的伦理边界,强调“以人为本”的发展原则。
延续近年考研英语完形“科技+人文”双主线的命题风格,主题涉及:
• 人工智能:医疗诊断、自动驾驶、教育智能化;
• 可持续发展:碳中和路径、能源优化、污染监测;
• 教育公平:数字鸿沟、算法偏见、个性化学习。
年完形整体难度适中偏上,主要体现在:
• 词汇辨析精度高(如subtle与delicate);
• 逻辑连接词隐性要求强(如conversely与moreover);
• 上下文推断跨度大(第8题需结合首段末句与第二段首句)。
第一段围绕人工智能发展现状展开论述,核心观点为“技术双刃剑效应”。原文以AI's rapid advancement为切入点,列举其在三大领域的突破性应用:
但作者随即指出三大挑战:
此段高频考点词汇:
ambivalent(矛盾的)、unprecedented(前所未有的)、paradoxically(矛盾地)、substantiate(证实)
第二段聚焦人工智能在环境保护中的创新应用,核心逻辑为“技术赋能可持续发展”。具体案例包括:
然而存在三大现实瓶颈:
技术瓶颈:边缘计算能力不足导致实时监测延迟;
② 数据壁垒:环保数据跨部门共享率不足30%;
③ 伦理争议:AI监测是否构成“数字围栏”式监控?
本段典型逻辑连接词:
conversely(相反地)、notably(值得注意的是)、moreover(此外)
第三段探讨人工智能对教育公平的影响,提出“技术人文主义”理念。核心论点包括:
作者特别强调三个原则:
本段高频考点短语:
human-centered(以人为本)、technological determinism(技术决定论)、equitable access(公平获取)
subtle vs delicate
subtle强调细微差异(如subtle difference),delicate侧重脆弱易损(如delicate ecosystem)。2022年第6题正确选项为subtle,因描述“算法偏见”需突出隐蔽性特征。
conversely vs conversely
conversely表反向逻辑(如本题第二段首句),conversely为干扰项(拼写错误)。完形填空常设形近词陷阱。
年真题出现6处逻辑连接词,分布规律如下:
第8题考查underscore的同义替换,需结合上下文:
前文highlighted the challenges,后文emphasized the opportunities,故正确选项为underscore(强调),干扰项overlook(忽视)与语境矛盾。
第12题考查mitigate的搭配,原文mitigate the risks为固定搭配,需掌握mitigate + risk/negative impact高频组合。
重点把握文章主旨、段落主旨及逻辑主线。2022年真题主题为“AI发展的双面性”,主线为“现状→应用→反思”,明确主线可快速排除明显不符选项。
完形首句通常不含空格,是全文信息锚点。2022年首句"Artificial intelligence has transformed how we live and work"提示积极基调,后续转折词前需保留积极词性。
运用“三步推断法”:
① 前后词性判断(如空格后为名词则选形容词);
② 逻辑关系识别(转折/因果/并列);
③ 语境复现验证(代入选项看是否与上下文连贯)。
填空后通读全文,重点检查:① 逻辑连贯性;② 词汇搭配合理性;③ 语义一致性。2022年真题第15题通过复读发现inevitably与后文preventable矛盾,及时修正。
Artificial intelligence has transformed how we live and work. Its applications in healthcare, transportation, and education have yielded 1______ benefits, though paradoxically, they have also introduced new challenges. In medical diagnosis, for instance, AI systems have achieved 94% accuracy in detecting early-stage cancers—2______ a promising future for precision medicine.
However, concerns about data privacy and algorithmic bias remain3______. Facial recognition technology, for example, exhibits a 35% misidentification rate for non-white individuals, 4______ ethical questions about fairness in algorithmic decision-making.
Turning to environmental protection, AI offers innovative solutions for sustainable development. Google's DeepMind reduced data center energy consumption by 40% through 5______ cooling optimization. Similarly, Beijing's AI-powered monitoring system achieves real-time PM2.5 source analysis within 15 minutes, 6______ traditional methods' limitations.
Yet the technology's limitations cannot be ignored. Edge computing constraints often cause delays in critical monitoring applications, 7______ the need for more robust infrastructure. Moreover, data silos across government agencies hinder 8______ sharing, reducing overall system efficiency.
In education, AI-powered platforms have improved resource accessibility, but the digital divide persists. Rural schools possess only one-fifth the smart device density of urban counterparts, 9______ concerns about equitable access. Finland's solution—mandating AI literacy courses from primary school—provides 10______ guidance for policymakers worldwide.
(选项略,完整版含15个选项)
标准答案:
1. unprecedented 2. pointing to 3. paramount 4. raising 5. algorithmic
6. circumventing 7. underscoring 8. cross-agency 9. exacerbating 10. human-centered
解析要点:
• 第1题unprecedented(前所未有的)呼应前文transformed,体现AI突破性;
• 第4题raising(引发)与ethical questions构成固定搭配;
• 第7题underscoring(强调)需结合首段underscore同义复现;
• 第10题human-centered直接对应第三段核心理念。
