一、引言格理论(Case Theory)是生成语法理论中一个重要的模块。在早期的生成语法理论中,格理论作为句法规则的重要限制条件,有重要而独立的理论地位。最简方案被引入生成语法框架之后,格理论逐渐被融入词项特征理论中以形成更简洁更有概括力的运算机 I. Introduction Theory (Case Theory) is an important module in generating grammar theory. In the early generation of grammar theory, lattice theory as an important restriction of syntactic rules, there is an important and independent theoretical position. After the minimalist approach is introduced into the generated grammar framework, the lattice theory is gradually incorporated into the term feature theory to form a more concise, more generalized computer
