摘　　要：近年来,Sorace及其同事提出的接口假说在二语习得领域引起了热议。该假说试图解释二语习得最终阶段残存的对错交替现象,认为狭义句法属性完全可以被习得,而涉及句法和其他认知模块的接口属性可能不会被充分习得。本文详细讨论了接口假说的有关理论概念(如接口的界定及类型、语言现象的多重接口属性等)及其理论价值,揭示了接口假说存在的几个问题,如表述的模糊性、证据的局限性和解释力。接口假说相关研究如果能拓展至所有接口,涵盖更多的语言及语言现象,丰富研究视角,全面考察二语习得各发展阶段的接口属性问题,将有助于理论修正,增强其生命力。The Interface Hypothesis （IH） proposed by Sorace and her collaborators to account for residual optionality at the end state of SLA, has been recently a topic of heated discussion in the field of SLA. The hypothesis argues that narrow syntax properties are fully acquirable while interface properties involving syntax and other cognitive domains may not be fully acquired. This article is an elaborate discussion of the relevant concepts （ including definitions of interfaces and their classification, multiple interface properties of linguistic phenomena） and the theoretical value of IH, shedding light on such problems as lack of clarity in IH state- ments, limitations of supporting evidences, and IH ＇ s explanatory power. It is pointed out that the potency of IH can be increased through revisions if research on IH can be extended to all interface properties involved in all the developmental stages of SLA, covering more languages and linguistic phenomena from more diversified perspectives.
