叶斯柏森是一位公认的杰出语言学家 ,一生活跃于语言学的广阔领域 ,论著极丰。他的理论至今仍有很高的学术价值。叶氏认为语言是人类的一种活动 ,语言的生命在于形式和意义的相互作用 ,因此 ,在语言研究中必须坚持形式和意义相结合的原则。语法研究可以从形式出发探求其意义 ,也可以从意义出发寻求其表达形式。叶氏据此建立了他的新语法体系———二分体系。他引进了与句法范畴相应的意念范畴 ,建立了形式—功能—意念的三分体系 ,认为功能是形式和意念之间的中介。为适应描写的需要 ,叶氏提出了著名的三品说以及组合式和连结式的理论 ,在叶氏的理论中可以见到现代语言学的端倪 ,但是有关意念范畴和双向探索似乎还有些问题值得进一步研究 Ye Si Bo Sen is a recognized distinguished linguist, a life of leap in a vast area of ​​linguistics, an extremely rich book. His theory still has very high academic value. Ye think that language is a kind of human activities, language life lies in the interaction between form and meaning, therefore, must adhere to the principle of the combination of form and meaning in language research. Grammar research can explore its meaning from the form, but also from the meaning of seeking its expression. According to this, Yeh founded his new grammar system --- dichotomy. He introduced the categories of ideas that correspond to the scope of the syntactic category and established a three-part system of formality-function-idea. He thought that function is an intermediary between form and mind. In order to meet the needs of description, Yeh’s famous three-character theory and the theory of combination and connection can be found in the theory of Yip’s. However, there seems to be some problems about the category of ideas and two-way exploration further research
