定义 / 说明
Hedging（缓和表达）让论断不至于过于绝对。C2 级别中，它通过情态动词、副词、转述框架和谨慎动词组合，表达不同程度的把握、距离与开放性。它在学术写作、专业讨论和细腻论证中尤其重要，可让文本显得理性、基于证据、承认复杂性。但过度 hedging 会使论证无力或闪躲。关键是“精准控制确定性”。
关键规则
- 用 appear/seem/suggest/tend to/be likely to 等作谨慎论断。
- 用 might/could/may 降低确定性。
- 用立场框架：It appears that, One might argue that, It seems possible that。
- 当证据有限、解释开放或需礼貌时，应加强 hedging。
- 不要所有句子都同等模糊；证据强处应保持强陈述。
例句
- It appears that the data were incomplete. - 数据似乎不完整。
- One might argue that the policy was rushed. - 有人可能会认为该政策推进过快。
- The results suggest that demand is falling. - 结果表明需求在下降。
- This could indicate a wider problem. - 这可能表明更广泛的问题。
- The change is likely to affect small firms first. - 这项变化很可能先影响小企业。
常见错误
- ❌ This proves the policy was wrong when the evidence is limited. -> ✅ This suggests that the policy may have been wrong.
- ❌ It seems certainly that demand fell. -> ✅ It seems likely that demand fell.
- ❌ One might argue the plan failed because definitely the team was weak. -> ✅ One might argue that the plan failed, possibly because the team was weak.
