通过对汉语动词“认为”实际运用情况的分析，讨论陈述行为在实施程度上的变化，提出这种变化不仅可由不同的动词实现，而且可由同一动词承担；程度的变化也可降至零点以下，即不实施陈述行为。同时还指出动词条件的不完全性，提出语境条件是陈述行为在实施程度上变化的决定因素。 Through the analysis of the practical use of the Chinese verb “think”, this paper discusses the changes in the degree of implementation of the stated behavior, and suggests that such changes can not only be realized by different verbs, but also by the same verb; the change of degree can also be reduced below zero, That is, no statement of conduct. At the same time, it points out the incompleteness of the verb condition and proposes that the condition of the context is the decisive factor for the change of the stated behavior in the implementation degree.
