摘　　要：短语复杂度是语言发展的高级阶段,相关研究通过综合性短语复杂度指标探究宏观学习者背景因素或微观任务变量对语言产出的影响,并得出了语言形式的统计规律。但这些研究并没有考虑宏观、微观因素对短语复杂度发展的协同作用,针对语言指标统计规律解释也缺乏语言学理论的支撑。本研究基于国际亚洲英语学习者语料库网络(International Corpus Network of Asian Learners of English)中的口语独白语料库(50万词),综合学习者背景因素和任务情境探究对二语学习者口语短语复杂度的影响。基于Halliday功能语法理论视角,对五类精细化短语复杂度指标建立了路径分析模型,并对宏观因素与微观因素进行统计交互。结果表明,学习者背景宏观因素会对口语短语复杂度产生多维效应,任务情境的微观认知条件会影响人际意义的表达并与年龄产生显著交互作用。本研究考察了宏观和微观因素对口语产出影响综合机制,并对短语复杂度的发展给予功能意义的解释。Phrasal complexity represents the advanced stage of learner language development.It is often regarded as an important dimension in the investigation of the effects of macro learner backgrounds and micro task-related variables on language production and related research has accumulated ample findings concerning the statistical distribution of linguistic indices.However,the joint effects of macro-and micro-level variables remain under-examined,and the interpretation of statistical patterns of the complexity indices lacks the support from linguistic theory.Therefore,this study explores the effects of learner backgrounds and task cognitive conditions on EFL learners'oral phrasal complexity based on the International Corpus Network of Asian Learners of English(ICNALE)(500,000 words).This study establishes a path analysis model combining 5 fine-grained phrasal complexity indices,and investigates the interaction between learner backgrounds and task cognitive conditions(task readiness)through the lens of Halliday's Systemic Functional Grammar.Results show that the macro-level learner backgrounds generated multi-dimensional effects on oral phrasal complexity while microlevel cognitive conditions interacted with age and affected the expression of interpersonal meaning.This research has converged the effects of macro and micro variables on oral production and provided a functional perspective on the development of learners'phrasal complexity.
