摘要
作为二语习得研究的重要组成部分,词汇评估不仅有助于了解学习者第二语言的掌握程度和学习者的共有特点,而且对促进二语教学具有重要意义。本文以非英语专业(大学英语)学生的定时作文为语料,通过自建小型历时语料库和Complete Lexical Tutor提供的Vocabprofile功能来分析语料库中的数据,结果表明:词汇发展总体来说是随着年级的增加呈现上升趋势,但上升幅度不显著。高频词中学术词汇(AWL)的变化基本上呈线性增长;词汇的多样性不断提高,学习者用词范围变宽;比起学习者词汇多样性和复杂性的变化幅度,词汇密度的变化呈现出缓慢上升趋势。
Lexical evaluation has undoubtedly made much contribution to the study of second language learning. It not only casts some light on the process of second language learning, but also helps us gain some insights into the common characteristics shared by language learners, which is believed to be of great help to language teachers and language learners alike. Based on the corpus of non-English major students＇ timed compositions, this paper tends to analyze the data in the mini self-buih diachronic corpus with the help of ＂Vocabpmfile＂ provided by Complete Lexical Tutor. The findings are as follows： lexical development in general in- creases along with the grade, but the increase is not significant. Academic word lists show a linear increase, the lexical variation is also rising and learners have a wider range of words to choose from. Compared with the lexical variation and lexical sophistica- tion, lexical density shows a slower increase.
