常见误用提醒
使用 debilitated：I am very debilitated after the exam. → I am exhausted after the exam. (debilitated 通常描述严重或长期的虚弱，如疾病所致；日常疲劳用 exhausted 或 tired 更自然。)
使用 debilitated：He debilitated from the accident. → He was debilitated by the accident. (debilitated 作为形容词或过去分词，常需与 be 动词连用构成被动语态，表示状态。)
使用 deteriorate：The situation is deteriorating worse. → The situation is deteriorating. (deteriorate 本身已包含“变得更糟”的意思，加上 worse 会造成语义重复。正确用法是直接使用 deteriorate 或说 getting worse。)
