语言信息单位是科斯托马罗夫近年来语言国情学研究中的一个重要的内容。该单位具有文化符号和语言符号的双重性质,从内容上看是一个浓缩的文本,在交际中有潜在的文化语用功能。当前研究者主要以“词汇背景理论”和“言语交际策略”为基础、初步构建语言信息单位理论。对它们的系统研究,不仅可以完善语言国情学理论,而且能满足人们日常交际的迫切要求。 Language information unit is an important part of Kostomarov’s study of linguistic conditions in recent years. The unit has the dual nature of cultural symbols and linguistic signs, and is a condensed text in terms of content. It has potential cultural and pragmatic functions in communication. The current researchers primarily based on the “vocabulary background theory” and “speech communication strategy” as the foundation, the initial construction of language information unit theory. The systematic study of them can not only improve the linguistic theory, but also meet the urgent requirements of people’s daily communication.
