本文首先介绍并肯定沈家煊(1995,2004)对“有界/无界”理论的阐述与所作的贡献,并认为该理论对语言现象的解释是有作用的。但是如何更准确地认识与理解“有界”与“无界”这对概念,怎么更正确地使用“有界”与“无界”理论来解释现代汉语的一些语法现象,似还需要进一步思考与探讨。本文提出了一些值得进一步思考与探讨的问题。最后文章指出,我们提出上述这些问题与看法,并非要否认在人的认知上存在“有界”与“无界”对立这一事实,更不是要否认“有界”与“无界”的运用价值,只是想说明,语言现象极为复杂,我们对某个具体的句法现象,可以根据研究的不同需要或实际应用的不同需要,采用不同层面的解释。科学研究贵在探索与创新,而要进行有效的探索,必须坚持多元论,善于从多个视角、多个方位、多个层面,运用多种理论去思考,去分析,去研究,从而将学科不断推向前进! This article first introduces and affirms Shen Jiayu’s (1995, 2004) elaboration and contribution to the theory of “bounded / unbounded”, and holds that this theory has an effect on the interpretation of linguistic phenomena. But how to understand and understand the concept of “boundedness” and “unboundedness” more correctly, how to interpret some grammatical phenomena in modern Chinese more correctly using the theories of “boundedness” and “unboundedness” , It may also need further thinking and discussion. This article presents some issues that deserve further thought and discussion. In the last article, we point out that the above questions and opinions are not intended to deny the fact that there is a contradiction between “bounded” and “unbounded” in human cognition, not to deny that “bounded” The value of “unbounded ” just means that language phenomena are extremely complicated. We can interpret a specific syntactic phenomenon at different levels according to the different needs of the research or the different needs of practical application. Scientific research is in the process of exploration and innovation. To conduct effective exploration, we must adhere to pluralism and be good at thinking, analyzing and researching from multiple perspectives, directions and levels and using multiple theories to continuously study disciplines Push forward!
