摘　　要：本研究采用英语专业学生四年的口语跟踪语料,用流利性、词汇多样性与词频广度三个指标分析口语词汇的使用,并与美国大学生的语料进行比较,旨在揭示其变化的趋势与特点。学习者语料源于2001年入学的56名英语专业学生,他们每年在语言实验室里完成一篇议论文文体的口头作文。本族语语料源于15名美国大学生,其口头作文的要求同于中国大学生。研究结果表明,学习者总体样本在流利性、词汇多样性和词频广度上的发展呈上升趋势,与本族语大学生的表现形成连续体。4年级学生在流利性和词汇多样性方面显著低于本族语大学生,但在词频广度上的差别与本族语大学生的差异不具有统计意义。2-3年级是三个指标变化的最佳时段。三个指标起点不同的组别,进步轨迹不完全相同。低起点组进步显著大于中起点组,中起点组稍快于高起点组。This paper reports a longitudinal study on the changes in speaking vocabulary by English majors through four years’ learning, which was then compared with the native speakers’ performance. The English learners involved in the study were 56 students who were enrolled in a university in 2001. They were asked to complete an oral task by producing a three_minute monologue after three minutes’ preparation in a language lab. The native speakers were 15 American college students who accomplished the same task as the English learners. The developmental changes were measured in terms of three indexes: fluency, word variations and lexical frequency profile. The performance on the three indexes of the students across four years and the native speakers form a continuum. However, Year Four students were significantly lower in fluency and word variations than native speakers, but similar to the native speakers in lexical frequency profile. The period between Year Two and Year Three saw the most noticeable progress. The students with different starting levels of the three indexes varied in terms of their changes. The low_level group made greater progress than the middle_level group which produced slightly faster progress than the high_level group.
