近年来,认知语言学者重视研究隐喻,但隐喻的性质、作用等问题尚须探讨。隐喻是相似客体在社会文化环境中通过语言在言语机制和言语活动中的代替,要多角度研究隐喻。隐喻是一种认知方式,但不是唯一的也不是最主要的认知方式。不管在言语机制或言语活动中,隐喻固然重要,直赋其事更不可少。隐喻映射的主要是事物的相似点,而不是整个事物的代替。 In recent years, cognitive linguists pay more attention to the study of metaphor, but the nature and function of metaphor should be discussed. Metaphor is the similar object in the social and cultural environment by language in the speech mechanism and speech activity instead, multi-angle study metaphor. Metaphor is a way of knowing, but not the only and most important way of knowing. No matter in the speech mechanism or verbal activity, metaphor is important, it is even more indispensable. Metaphor mapping is mainly the similarity of things, rather than the whole thing instead.
