定义 / 说明
在 C2，残留错误常不在主干句法，而在复杂名词短语内部：冠词、介词、所属、主谓一致等“最后一公里”细节。它们虽小，却会显著削弱高级文本的可信度。由于名词短语密度高，草稿阶段这类错误很易漏掉。典型问题是冠词选择不当、介词搭配不自然、或主谓一致被邻近词干扰。高级校对必须聚焦名词短语内部结构。
关键规则
- 先找 head noun，再检查 article / modifier order / verb agreement。
- 固定或半固定搭配中的介词要仔细核对：impact on, interest in, responsible for。
- 一致关系要跟真正中心词，而不是靠近的复数词。
- 长名词短语可尝试“从后往前”慢速校对。
- 很多 C2 错误是局部细节错，不是整句结构错。
