• immune

  Immune emphasizes built-in resistance or protection, often used with 'to', suggesting something cannot affect you even if it tries; common with criticism, emotions, or diseases.

  Years of criticism have made her immune to negative comments from strangers.

  多年的批评已经让她对陌生人的负面评论完全免疫。

• untouched 本词

  Untouched is more literal and vivid, suggesting something has not been touched, altered, or damaged at all, often describing places, objects, or traditions preserved intact.

  untouched更具字面性和画面感，表示某事物完全未被触碰、改变或损坏，常用来描述地方、物品或传统被完整保留。

  The old forest has remained untouched by loggers for over a century.

  这片古老的森林一个多世纪以来一直未被伐木者触碰。

• unaffected

  Unaffected is more formal and neutral, simply stating that no change or influence occurred, commonly used with 'by' for measurable outcomes, situations, or emotions.

  unaffected语气更正式、中性，仅陈述没有发生变化或影响，常与“by”连用，用于描述可衡量的结果、状况或情绪。

  该公司的利润在很大程度上未受经济衰退的影响。

All three mean not affected by something. Immune stresses built-in resistance, often with 'to', suggesting something cannot affect you. Untouched is literal and vivid, meaning not touched or changed at all. Unaffected is formal and neutral, simply stating no change occurred, often with 'by'.

这三个词都表示“没有被某种事物影响或改变”，但语气和用法不同：immune强调天生或后天获得的抵抗力，untouched强调字面上未被触碰或改动，unaffected语气更正式中性，只是陈述没有产生变化。这里不比较unaffected表示“不做作、自然纯朴”（如unaffected manner）的义项，也不比较untouched表示食物“未被动过、未被食用”的义项，更不涉及immune在医学上“对某疾病具有免疫力”的专业用法（如immune system这一固定搭配）。
