Abstract: As a complex syntactic phenomenon，island effects has long been controversial. T-G grammar approaches the phenomenon from the perspective of EC and adjacency principles but fails to explain all categories of island effects and the different move patterns for arguments and non-arguments advocated from the perspective of T-G are also disputable．The experimental studies confirms that island effects are syntactic anomalies but makes little contribution to clarifying its specific mechanism．The present study approaches the phenomenon from the perspectives of both empty position and syntactic and semantic ambiguities．

摘要： 岛效应作为复杂的句法现象，其研究历来存在争议。转换生成语法理论通过空语类原则和邻近原则来解释这一现象，但难以涵盖所有岛效应现象，其对论元和非论元所采取的不同移位原则也存争议。相关实证研究证明句法岛效应属于句法违例，但对其具体形成机制不甚了然。本研究从容留空位和句法语义模糊的角度试图给句法岛效应新的理论阐释。
