Abstract
According to Bondarko's functional grammar theory, combined with the corpus of the Russian State Corpus and the BCC Corpus of Peking University, this paper discusses the language expression means of each subfield of the functional semantic field of spatial orientational category in Russian and Chinese Languages, and constructs the structure of directional functional semantic field. The research results of this paper will help Chinese students better grasp the grammatical structure of Russian spatial direction prepositions. At the same time, This paper systematically compares and analyzes the characteristics of the expressions about the directional functional semantic field in the two languages, provides theoretical guidance for Chinese college students to learn Russian, and provides theoretical support for teachers engaged in Russian teaching.
