网络语言从网络上流传到了现实生活中,已经成为了我们生活的一部分。网络语言中所使用的修辞手法-隐喻,不仅使表达生动形象,也在更深层次上隐喻了我们赖以生存的社会的变革和发展。本文主要从隐喻的两个身份-修辞手法和认知工具,来分析网络语言所使用的修辞手法和网络语言给我们提供的认识世界的新视角。 Internet language has spread from the Internet to real life and has become a part of our life. Metaphor, a rhetorical device used in cyber language, not only makes vivid expression but also metaphorizes the transformation and development of the society to which we depend for survival. This paper mainly analyzes the rhetorical techniques used by cyber-linguistics and the new perspectives provided by cyber-linguistics to us to understand the world from the two identities of metaphor - rhetorical devices and cognitive tools.
