"Prevent from" 是英语中表示"阻止…发生"或"妨碍…做某事"的动词短语,其核心用法由权威语言学著作《牛津英语语法指南》指出:该结构遵循"prevent + 宾语 + from + 动名词"的固定搭配,强调通过外力干预使特定行为无法完成(Huddleston & Pullum, 2005)。例如世界卫生组织在《传染病防控手册》中使用的例句:"Vaccination prevents children from contracting measles"(疫苗接种能防止儿童感染麻疹),体现该短语在正式语境中的专业应用。
剑桥大学英语语料库(Cambridge English Corpus)收录的实证数据显示,该短语在学术写作中多用于描述物理阻隔、制度限制或预防措施,如:"Safety rails prevent workers from falling into machinery"(安全护栏防止工人跌入机械装置)。《朗文当代英语词典》特别说明,在被动语态中"from"可省略,如"She was prevented (from) leaving the country"(她被限制出境),这种用法常见于法律文书中。
美国疾病控制与预防中心(CDC)在《公共卫生干预报告》中强调,"prevent from"与近义词组"stop from"存在细微差异——前者更强调预防性措施,如"Face masks prevent the virus from spreading"(口罩阻止病毒传播),后者侧重即时性制止行为。这种语义区分得到《韦氏英语用法词典》的佐证,建议在医学、工程等专业领域优先使用"prevent from"以确保表述严谨性。
