空语类PRO的理论误区

摘要

Empty category PRO plays an important role in the theory of generative grammar, and it is an implicit noun compo-nent with semantic and syntactic functions, but without a sub-stantial form of speech sound in language structure. It has the theoretical and factual basis for its existence under the framework of Government and Binding Theory and Minimalist Program The-ory. With the deepening study of Minimalist Program theory, the necessity and rationality of the existence of PRO is questioned.%空语类PRO在生成语法理论中具有重要地位，它是具有语义、句法功能，在语言结构中没有语音实体形式的隐性名词成分。在管约束论和最简方案理论框架下有其存在的理论依据和事实根据。随着最简方案理论研究的深入， PRO存在的必要性和合理性也受到质疑。
