定义 / 说明
C2 阶段很多错误不再是显性语法错，而是搭配错。一个短语可能“能懂、形式也对”，但仍不自然，因为英语偏好另一组词。高级学习者需要控制的不只是词义，还包括习惯性搭配。强搭配控制直接影响流利度、文体和可信度，尤其在写作和演示中。这是“高度准确英语”与“仅语法正确英语”的关键差异之一。
关键规则
- 把高频搭配作为 chunks 记忆：strong evidence, raise an issue, reach a conclusion。
- 不要假设近义词在同一搭配里都成立。
- 关注名词、动词、形容词、介词各类搭配。
- 高级写作中，搭配选择常比单词字面意义更关键。
- 修改时不只查语法，也要查搭配自然度。
例句
- We need to raise an issue before the vote. - 投票前我们需要提出一个问题。
- The report provides strong evidence. - 报告提供了有力证据。
- She made a serious mistake. - 她犯了严重错误。
- They reached a mutual agreement quickly. - 他们很快达成了共同协议。
- The news had a major impact on sales. - 这条消息对销量产生了重大影响。
常见错误
- ❌ We need to lift an issue. -> ✅ We need to raise an issue.
- ❌ The report provides powerful evidence. -> ✅ The report provides strong evidence.
- ❌ They did a big mistake. -> ✅ They made a serious mistake. / ✅ They made a big mistake in informal speech, but serious mistake is more natural in formal writing.
