本文基于动态系统理论,采用移动极值图、去趋势化、蒙特卡罗模拟、再抽样技术、移动相关系数等分析方法,对美国某大学一名英语母语者汉语作文的词汇和句法动态发展进行了为期1年的跟踪研究。研究结果发现,经过1年时间的学习,学习者在词汇变化性、词汇复杂性、句法复杂性和语言准确性四方面的变化呈现出跳跃式、阶段性和非线性发展的特点,在发展过程中存在高峰和低谷、进步与后退的交替。此外,学习者语言知识内部各维度发展并不同步,在词汇和句法发展的过程中存在竞争-支持关系的转移,这反映了词汇和句法子系统的发展对认知资源的不同需求。可见,英语母语者汉语书面语发展具有明显的动态性和变异性。
Based on the dynamic system theory, this paper uses dynamic extreme value graph, de-trending, Monte Carlo simulation, resampling technique and moving correlation coefficient to analyze the dynamic development of vocabulary and syntax of a Chinese EFL student in a university in the United States A one-year follow-up study. The study found that after a year of learning, learners showed the characteristics of leaping, staging and non-linear development in the aspects of lexical change, vocabulary complexity, syntactic complexity and language accuracy. In the process of development There are peaks and valleys, the alternation of progress and retreat. In addition, the development of learners’ linguistic knowledge is not synchronized in all dimensions. There is competition-supportive relationship transfer in the process of lexical and syntactic development, which reflects the different needs of cognitive and cognitive resources in the development of lexical and syntactic subsystems. Can be seen that the development of Chinese written language by native speakers of English has obvious dynamics and variability.
