中国古典诗词是先人们智慧的结晶,蕴含了深厚的文化底蕴。苏轼的《江城子·十年生死两茫茫》是悼亡词中的佳作,但是目前还很少有人对其进行系统功能语言学方面的分析。该文尝试用系统功能语言学概念功能中的及物性系统分析该词的特征,揭示了功能语言学理论有助于人们理解古诗词的主题思想和语言特点。 Chinese classical poetry is the crystallization of wisdom of predecessors, contains profound cultural heritage. Su Shi’s “Jiangchengzi · ten years of life and death,” is a memoir of mourning words, but few people still analyze it systematically in functional linguistics. This paper tries to analyze the characteristics of the word by using the system of functional linguistics and the system of physical properties, revealing that the theory of functional linguistics helps to understand the theme and language features of ancient poetry.
