常见错误

❌ 错误:The water is untreated with chemicals.
✓ 正确:The water is untreated.

'untreated'本身已表示'未经处理',添加'with chemicals'冗余且可能引起歧义,应直接使用'untreated'简洁表达。

❌ 错误:He untreated his wound.
✓ 正确:He left his wound untreated.

'untreated'是形容词,不能直接作动词使用;正确表达应用动词短语如'leave untreated'来描述未处理的状态。

raw

'raw'强调天然、未加工的状态,常用于食物或材料;'untreated'更侧重缺乏处理过程,可能涉及安全或效果,如医疗或环境语境。

Raw vegetables are healthy, but untreated water may contain harmful bacteria.

unprocessed

'unprocessed'泛指未经过任何加工或改变,较中性;'untreated'常隐含需要或应该处理但未进行,带轻微负面或警告意味。
