本文的主要目的是考察“非理想”2的语言事实在语言学理论建设中的重要地位与作用。为此,本文从语义、句法、功能相结合的角度,将生成语法无法解释的“非理想的”NP+(will)BE+NP(boys will be boys)句式纳入非范畴化理论框架下统一解释...本文的主要目的是考察“非理想”2的语言事实在语言学理论建设中的重要地位与作用。为此,本文从语义、句法、功能相结合的角度,将生成语法无法解释的“非理想的”NP+(will)BE+NP(boys will be boys)句式纳入非范畴化理论框架下统一解释。研究表明,这种尝试是可行的、有效的。由此证明,“非理想的”语言事实并非是非理想的,它们对深化和扩展语言学理论具有不可估量的作用。语言事实的理想与否取决于理论研究的取向和理论的背景假设。本文还附带考察了在英汉两种语言中,该句式在意义上的异同。深入考察发现,将该句式称之为“同义反复”只是一种基于表象的理论抽象,只能说明部分的语言事实,因而是欠妥的。展开更多
