高职英语学习者口语词汇产出能力的发展模式

摘要

基于高职商务英语专业一至三年级89名学生一次同一时间的限时口语测试,从词汇广度和词汇深度两个方面的7项指标入手,研究其口语词汇产出能力的发展模式。结果显示,对高职英语学习者而言,一至二年级期间口语词汇的产出速度发展迅速,高频词使用倾向明显;二至三年级期间口语表达中的低频词明显增多,词汇的重复率明显减少,语义搭配及语用准确性显著提高。这与高职英语学习者年级增长,口语能力提高,词汇习得观念和产出策略的改变有关。%Based on the same timed oral test of 89 vocational students from three grades of business English majors,the paper analyzes the patterns of development in the oral vocabulary productivity according to 7 indicators of breadth and depth.Results show that for vocational English learners from grade one to grade two,the oral vocabulary productivity is characterized by the fast production speed and the large number of high frequency words;while for those from grade two to grade three,the oral vocabulary productivity is marked by the significant changes in the increase of the low frequency words,the reduction of the repetitive rate and the improvement of the collocation and pragmatic accuracy.These developmental patterns may be related to the gradual improvement of the speaking ability,and the subtle changes of acquisition concept and productive strategies of oral vocabulary along with growth of the grade.
