常见误用提醒
使用 punitive：He got a punitive for his mistake. → He faced punitive action for his mistake. (punitive 是形容词，不能直接用作名词。应使用名词短语如 punitive action 或 punitive measures 来表示惩罚性的事物。)
使用 punitive：The punishment was very punitive. → The punishment was severe. (punitive 本身已含有惩罚的意思，与 punishment 连用可能显得冗余。在描述惩罚的严厉程度时，使用 severe 或 harsh 更自然。)
使用 penal：He received a penal for speeding. → He received a penalty for speeding. (“penal”是形容词，不能直接用作名词表示“处罚”；应使用名词“penalty”或“punishment”。)
