功能语言学认为词汇隐喻和语法隐喻是同一现象的不同实现形式,但二者差异性较大。本文主要研究词汇隐喻和语法隐喻语篇功能的差异性。词汇隐喻作为认知框架,属于语篇的宏观结构;语法隐喻作为隐喻识解,属于语篇的微观结构。 Functional linguistics holds that lexical metaphor and grammatical metaphor are different forms of realization of the same phenomenon, but the two are quite different. This paper mainly studies the differences between the textual metaphors and grammatical metaphorical texts. Lexical metaphor, as a cognitive framework, belongs to the macroscopic structure of discourse. Grammatical metaphor, as a metaphorical solution, belongs to the microscopic structure of discourse.
