"N1bu neng dang N2 V"is a multifunctional construction in that it can express both attribute and value judgement,with some subtle differences in form.Conceptual metaphor and the change of point of view contribute to the development of"N1bu neng dang N2 V"from a grammatical construction to a rhetorical one,and analogy also plays a role.The expansion of the N1 schematic slot and the habituation of N2 are the manifestation of rhetoricalization.While attribute judgement is the result of semantic inference,the conversational implicature of value judgement derives from pragmatic inference.The attribute judgment is intended to tell general truth,while the value judgment is intended to convey not only general truth,but also the speaker's negative evaluation.Grammatically,there exist negation and affirmation in the variability of social value relationship,and normality and abnormality in the semantic understanding.
