隐喻一直以来吸引了众多研究者的兴趣,而隐喻认知研究则更是进入了一个大发展时期。认知语言学家认为隐喻是一种思维方式,而隐喻语言则是隐喻思维的表现形式。本文旨在通过对隐喻语言进行分析,来论证隐喻的必要性以及隐喻的不对称性、系统性、和非任意性等特点。 Metaphor has always attracted the interest of many researchers, but metaphorical cognitive research is even more into a period of great development. Cognitive linguists think that metaphor is a way of thinking, while metaphorical language is a manifestation of metaphorical thinking. The purpose of this paper is to demonstrate the necessity of metaphor as well as the asymmetry, systematicness and non-arbitrariness of metaphor by analyzing metaphorical language.
