"that is to say"是一个英语惯用表达,主要用于对前述内容进行解释、澄清或补充说明,其功能相当于中文的"即""也就是说"或"换句话说"。该短语在学术写作、法律文书和正式交流中使用频率较高,具有以下语言学特征:
逻辑连接功能
作为语篇标记语(discourse marker),其核心作用在于建立前后语义的等同关系。牛津英语词典将其定义为"used to introduce a more detailed explanation of something that has just been stated",强调其解释性功能。
句法灵活性
可作插入语(如"The meeting is postponed, that is to say, until next Monday")或连词使用(如"We need volunteers, that is to say people willing to work overtime"),这种灵活性使其在复杂句构建中具有重要作用。剑桥词典特别指出其在不同位置使用时标点符号的差异。
语义层级构建
在学术论证中常用于建立"主张-阐释"的递进结构,例如:"The results were inconclusive, that is to say, the experiment needs replication under controlled conditions"。根据《英语语用学手册》,这种用法能有效提升论述的严谨性。
跨语言对应差异
虽然字面直译为"那就是说",但在实际应用中需注意语境差异。例如在法律文本中,其严谨程度高于中文的"换句话说",更接近"特此说明"的正式程度。《法律英语写作指南》建议在合同条款解释时优先使用该短语。
“that is to say”是一个常用的插入语短语,主要用于进一步解释或澄清前面所述的内容,相当于中文的“换句话说”“也就是说”。以下是详细解析:
核心功能
该短语用于对前文进行补充说明或更精确的表述,常见于正式或学术场景。例如:
“He prefers classical music, that is to say, works by Mozart and Beethoven.”(他喜欢古典音乐,即莫扎特和贝多芬的作品。)
语法结构
通常在句中作插入语,前后用逗号隔开。例如:
“The deadline is flexible, that is to say, we can extend it if necessary.”(截止日期是灵活的,也就是说,必要时可以延长。)
同义替换
可替换为“in other words”“namely”或“i.e.”(拉丁语缩写)。例如:
“The event starts at 8 PM, i.e., 20:00 in 24-hour time.”(活动晚上8点开始,即24小时制的20:00。)
使用场景
注意事项
避免过度使用,以免显得冗长。在非正式场合可简化为“like”或“meaning”等更口语化的表达。
