摘要
This study draws on usage-based approach to language learning and investigates the role of syntactical indeterminacy and token frequency in constructional acquisition, for which reflexive verb constructions were selected as the testing field. Syntactic structures of reflexive verbs are either by reflexive constructions or adjectival passive, which have a polysemous interrelationship within the verb. To examine whether syntactic indeterminacy and token frequency play a role in the acquisition of reflexive verb constructions, a test of reflexive verb constructions and a baseline test formed with transitive verbs were developed and administered to L2 learners of an intermediate proficiency level. The findings show： （1） L2 reflexive verb constructions were less acquired than transitive constructions, suggesting that syntactic indeterminacy had an impact upon sentence production; （2） no significant difference was found between the productions of reflexive constructions and adjectival passives, but descriptive statistics showed that learners were attracted to the adjectival passive for production; （3） production of both syntactic structures reflected token frequency trend from COCA, indicating the important role of frequency in complex constructional acquisition.
本研究在基于使用的语言学习的理论框架下调查句法可选择性和类型频率对英语反身动词构式习得的影响。英语反身动词的句法结构可以通过反身构式和形容词被动构式实现,两者是一种词内多义关系,表现出句法可选择性特征。为了考察句法可选择性和类型频率对反身动词构式习得的影响,本研究设计反身动词构式测试和及物动词测试,后者作为参照测试,并在二语学习者中进行检测。研究结果表明:1)英语反身动词构式的习得明显低于参照测试,证明句法可选择性影响句法的习得;2)反身构式和形容词被动构式习得之间无显著差异,然而初步数据显示,学习者似乎更易于习得形容词被动构式;3)二语学习者的反身构式和形容词被动构式的产出频率与COCA的类型频率走向一致,表明类型频率在复杂构式习得中的重要作用。
