on condition that
英 /ɒn kənˈdɪʃən ðæt/美 /ɑːn kənˈdɪʃən ðæt/
conj. 连词(引导条件状语从句)
在……条件下;只要;假如
基本释义
该词组的本义为“在……的条件下”,强调某一结果或行为的发生必须以另一条件为前提。其引申义包括“只要”和“假如”,用于表达一种限定性的承诺或协议。本义侧重于客观条件,引申义则更多带有主观意愿或约定色彩。
构词与来源
该词组由介词“on”、名词“condition”和连词“that”构成。“condition”源自拉丁语“condicio”,意为“协议、条件”。整体构词逻辑为“在……条件之上”,即以某条件为基础。记忆时可联想“on the condition that”表示“在……条件下”,与“if”相比更正式、更具体。
常见语境
该词组常用于正式场合,如法律文本、合同条款、学术写作和新闻报道,表示明确的先决条件。在商务邮件中,用于提出附带条件的建议或协议。在日常口语中较少使用,若使用则语气较为正式或带有强调意味。例如,法律文本中“The contract is valid on condition that both parties sign it.”,新闻报道中“The aid was provided on condition that it be used for reconstruction.”。
语法提示
该词组引导条件状语从句,从句通常用陈述语气,但有时根据语境可用虚拟语气(如“on condition that he come”)。注意“that”不可省略,且从句中常使用“should”或动词原形表示虚拟。易错点:与“if”混用,但“on condition that”更正式,且强调条件为双方约定的前提。
同义词区别
与“if”相比,“on condition that”更正式,且暗示条件为经过协商或明确规定的。与“provided that”或“providing that”意义相近,但“on condition that”更强调条件本身,而“provided that”更倾向于“如果提供某条件”。与“as long as”相比,后者更口语化,且强调持续性条件。例如,法律文件多用“on condition that”,日常口语多用“as long as”。
常见误区
该词组属于正式语域,常用于书面语,口语中过度使用会显得生硬。无褒贬色彩,但通常带有“限定”或“约束”的意味。常见误用包括省略“that”或将其与“if”随意互换,导致语气不匹配。另注意从句中动词形式的选择,正式文体中可能用虚拟语气。
