so that...
英 /səʊ ðæt/美 /soʊ ðæt/
conj. 连词
以便;所以;以致
基本释义
so that 的核心含义有两个:一是引导目的状语从句,表示“以便,为了”,强调主句动作是为了实现从句中的目的;二是引导结果状语从句,表示“所以,以致”,强调主句动作导致从句中的结果。两者在语义上有引申关系:目的指向未来,结果指向过去或已发生的事实。例如“He studies hard so that he can pass the exam.”(目的)与“He studied hard, so that he passed the exam.”(结果)。前者是尚未实现的意图,后者是已实现的自然结果。在口语中,so that 常简化为 so,但书面语中保留 that 更正式。
构词与来源
so that 由副词 so(如此,这样)和连词 that(引导从句)组合而成。so 源自古英语 swā,表示“以这种方式”;that 源自古英语 þæt,是中性指示代词。两者结合最早出现在中古英语时期,表示“以这种方式,以至于”。记忆时可拆解为 so(如此)+ that(那样),即“如此……以致于”,从而联系到目的和结果的双重含义。
常见语境
so that 广泛用于各种语域。在学术写作中,常用来明确研究目的或逻辑关系,语气正式,如“The experiment was designed so that variables were controlled.”;在商务邮件中,用于说明请求或建议的意图,如“Please review the document so that we can finalize the plan.”;在日常口语中,常简化说成 so,语气随意,如“I left early so I could catch the bus.”;在新闻报道中,用于解释原因与结果,如“The company cut costs so that profits could rise.”;在法律文本中,so that 用于精确表述条件或结果,如“The contract shall be void so that no party is liable.”。不同场景下,so that 均保持“目的”或“结果”的核心意义,但正式程度和从句结构略有差异。
语法提示
so that 是连词,引导状语从句。引导目的状语从句时,从句中常使用情态动词 can, could, may, might, will, would 等,表示可能性或意愿;引导结果状语从句时,从句中通常不用情态动词,而用一般时态。常见句型:主句 + so that + 从句(目的);主句,+ so that + 从句(结果,常加逗号)。易错点:目的从句中误用 will 或 would,应使用 may/might/can/could 更正式;结果从句中误加情态动词。另外,so that 与 so...that... 不同,后者表示“如此……以至于”,so 后接形容词或副词,而 so that 中 so 不修饰任何词。
同义词区别
so that 与 in order that 同义,均引导目的从句,但 in order that 更正式,且常置于句首;so that 更常用,且可引导结果。与 so...that... 区分:so...that... 中 so 修饰形容词/副词,that 引导结果从句,如“He is so tired that he can't walk.”;而 so that 中 so 和 that 连用,不修饰词。此外,to do 也可表目的,但只能接不定式,主语需一致,如“He studies hard to pass.”,而 so that 从句主语可不同。
常见误区
so that 在正式写作中应避免省略 that,口语中可省略。引导目的从句时,若主句为现在时,从句常用 may/can;若主句为过去时,从句用 might/could。结果从句中,so that 前常有逗号,且从句通常表示客观结果,不带主观意图。常见误用包括将 so that 与 so...that... 混淆,或在目的从句中误用 will/would。语域上,so that 中性,但 in order that 更正式。无褒贬色彩。
