完形填空考查内容:四大维度解析命题底层逻辑
词汇掌握:词义辨析与搭配能力(占比42%)
考查高频词义辨析、固定搭配、近义词辨析,尤其关注:动词+介词/名词、形容词+介词、名词+介词三类搭配。
真题示例(2023年):
原文:Many scholars remain ______ the use of AI in academic writing.
选项:A. skeptical about B. confident in C. excited about D. curious for
解析:考查“be + 形容词 + about”结构。Skeptical about为固定搭配(对……持怀疑态度),而confident in用于“对……有信心”,excited about用于人的情绪,curious for搭配错误(应为curious about)。正确答案:A。
高频考点词组:
- • take...into account(考虑)
- • be skeptical about(对……怀疑)
- • make a distinction between A and B(区分A与B)
- • in terms of(在……方面)
- • as a result of(由于)
语法运用:时态、语态、主谓一致、非谓语动词(占比28%)
重点考查非谓语动词(不定式、动名词、分词)的语境适配性,以及被动语态与主动语态的逻辑选择。
真题示例(2021年):
原文:The algorithm, ______ by researchers at MIT, processes data in real time.
选项:A. developed B. developing C. to develop D. having developed
解析:非谓语动词作后置定语。因algorithm与develop为被动关系,且动作已完成,应用过去分词developed。Developing表主动进行,to develop表将来,having developed表完成但主动。正确答案:A。
高频语法陷阱:
- • 介词后必须接动名词(如:insist on doing)
- • “the + 形容词”作主语时,谓语用复数(如:the elderly are...)
- • 动词不定式作主语时,用it作形式主语(It is important to...)
语篇理解:段落衔接与逻辑关系(占比20%)
考查连接词(如however, therefore, whereas)、指代关系(this/that/these/those)、同义复现(paraphrase)、反义对比(antonym)等。
真题示例(2024年):
原文:Traditional libraries are declining, ______ digital resources are growing rapidly.
选项:A. while B. since C. because D. as
解析:前后为对比关系(declining vs. growing),while表“然而”,用于对比;since/because/as表因果。正确答案:A。
逻辑连接词分类速查表:
| 逻辑关系 | 典型连接词 | 例句特征 |
|---|---|---|
| 并列/递进 | and, moreover, furthermore | 前句肯定,后句加强语气 |
| 转折 | however, whereas, on the other hand | 后句与前句观点相反 |
| 因果 | therefore, consequently, as a result | 后句为前句的结果 |
| 解释/举例 | for example, namely, that is | 后句对前句具体说明 |
逻辑推理:上下文推断与语境还原(占比10%)
考查通过空格前后句、段落主旨进行反向推理的能力,尤其在首段与尾段空格。
真题示例(2022年):
原文:The study aimed to ______ whether online learning could match the effectiveness of traditional classrooms.
选项:A. assess B. assume C. assert D. assign
解析:后文“match the effectiveness”暗示需“评估”效果,assess意为“评估”,符合语境;assume(假设)、assert(断言)、assign(分配)均与语境冲突。正确答案:A。
推理技巧:
- • 首段空格:优先考虑全文主旨词(如purpose, significance, challenge)
- • 尾段空格:关注总结性词汇(conclusion, implication, prospect)
- • 段中空格:用“代入法”读完整句,排除语义矛盾项
