摘　　要：二语发展中的变异是系统在自适应过程中,于整体层面上涌现出的高层次属性和特征,因而变异研究是在系统层级讨论复杂的运作机制。本研究从复杂动态系统理论视角,利用时间序列分析法对中国英语学习者口语发展中的词汇及句法在512个时间观测点位上的变异(模式、周期)情况进行了为期两年的历时研究。研究发现:1)变异是口语系统发展的动态性、复杂性和多维性的综合体现;2)口语词汇动态发展规律呈现同质性,句法发展规律呈现异质性;3)口语句法提升路径上的阶段性发展周期滞后于词汇,分布的时间跨度更长。本研究发现的动态发展规律和习得提升路径可为二语口语的精准教学和动态评价提供依据和参考。Variability in second language development is a high-level property that emerges from systemic self-adaptation at the holistic level.Thus,the study of variability involves the discussion of complex operating mechanisms at a systemic level.From a Complex Dynamic Systems Theory perspective,this study investigates the lexical and syntactic variability(patterns and periods)of Chinese English learners'spoken language development at 512 temporal observation points over 2 years using time series analysis.The results show that:1)variability is the comprehensive embodiment of the dynamic,complex,and multidimensional development of the spoken system;2)the dynamic development pattern of spoken vocabulary is homogeneous,while that of syntax is heterogeneous;3)the critical development period on the improvement path of spoken syntax lags behind that of vocabulary,and the distribution span is longer.The dynamic development patterns and acquisition improvement paths found in the study can provide a basis and reference for precise teaching and dynamic evaluation of L2 spoken language.
