模糊与精确是一对相反相成的概念。模糊理论在语言学中的应用,让我们逐渐认识到汉语时间词具有典型的模糊性。每一种时间划分的范围内,词语都具有模糊性特征。日常生活的绝大多数场合不需要精确性时间词。模糊性时间词的存在,不但源于日常认知方式,而且基于具有主观随意性、客观不确定性和结果非精确预期性。 Ambiguity and precision are opposite concepts. The application of fuzzy theory in linguistics has gradually realized that Chinese time words are typically ambiguous. Within each category of time, the words have the characteristics of fuzziness. The vast majority of daily life does not require the accuracy of time words. The existence of ambiguous time words stems not only from everyday cognitive modes but also from subjective discretion, objective uncertainty and imprecision of results.
