二语语体发展是复杂的、动态的,历时研究为考察发展过程中的变化提供微观视角。本研究自建二语学习者历时笔语语料库,从160位受试者在为期16周所写的4个不同题议论文中随机抽取3位不同语言水平的受试者的写作文本,建成观测语料库,并通过语料库分析软件Ant Conc3.4.1w对其进行词频、词汇密度,及在线修改次数等进行统计分析。结果表明,受试的二语写作词汇语体意识和能力均较低,个体间文本比较表明实词的过度运用程度不一,个体内文本比较显示,词汇语体的习得过程呈进步与倒退交织的非线性。
Second language development is complex, dynamic and diachronic studies provide a micro perspective on the changes in the development process. In this study, self-built L2 learners lasted the corpus of pen-written language, and the texts of three subjects with different linguistic levels were randomly selected from 160 different subject papers written by 160 subjects over a period of 16 weeks to construct an observational corpus , And through the corpus analysis software Ant Conc3.4.1w its word frequency, word density, and the number of online changes such as statistical analysis. The results show that the tested second language writing vocabulary has a low level of awareness and ability, and the comparison of individual texts shows that the degree of overuse of the substantive words varies from one individual to another. The comparison of individual text shows that the acquisition of lexical language is progressively and regressively interwoven Non-linearity.
