空间隐喻是人类认知的重要手段。本文运用认知隐喻理论解读曹雪芹名著《红楼梦》。本文选取比较常见的“上下”、“高低”两组空间概念来分析空间概念的隐喻功能。“上”、“下”、“高”、“低”构成的空间隐喻建构一个和谐的隐喻体系,为我们解读该作品提供重要的认知参照。在他们构筑的社会等级域、数量域、时间域、状态域中,“上”和“高”基本表示积极意义,“下”和“低”多表示消极负面因素。 Spatial metaphor is an important means of human cognition. This paper uses Cao Yuqin’s famous book The Dream of Red Mansions to interpret the theory of cognitive metaphor. This article selects the more common “up and down”, “high and low” two space concepts to analyze the metaphorical function of the concept of space. This metaphor constitutes a harmonious metaphorical system which provides an important cognitive reference for our interpretation of this work. In the social level domain, quantity domain, time domain, and status domain they construct, “on” and “high” basically indicate positive meaning, “under” and “low” denote negative negative factors .
