词汇短语与英语专业学生口语水平的研究

论文摘要

词与词之间的联系可以帮助二语习得者在习得二语的过程中更好的记忆与理解二语。词汇短语的研究也因此受到学术界广泛的关注。语料库与心理语言学研究的成熟以及语料库在外语教学中的应用使我们更全面更客观的考察二语习得者词汇短语的使用特征。本文基于中国英语专业学生的口语语料库,采用定性与定量分析,探讨不同英语口语水平的学习者在词汇短语的使用情况上是否存在显著差异;学习者在完成不同的英语口语任务时词汇短语的使用情况是否存在显著差异;以及英语专业在口语中所使用的词汇短语的总体特征。本文语料库选自SWECCL(中国学生英语口笔语语料库)的SECCL (中国学生英语口语语料库)中的子语料库。按照分组排名,前10名之内节选了30篇语料,排名为25—31之间的节选了30篇语料,分别分为两组:英语口语水平较高组与英语口语水平稍低组。又对60篇所选语料进行不同英语口语任务分组,任务A (故事复述),任务B(即兴演讲)和任务C(对话)。根据本文提出的词汇短语的可操作性定义,利用检索软件ANTCONC词块提取工具,研究者筛选出了符合定义的词汇短语。研究者参照计算式:词汇短语使用频率=(文本字数—词汇短语字数)/词汇短语个数,可以得到学习者的词汇短语使用频率,即:学习者使用的每个词汇短语出现在多少个单词中。研究发现:(1)水平较高的学习者比稍低的学习者更多的使用词汇短语,说明词汇短语的使用和口语能力的高低有较强的关系。(2)中国英语专业学生在完成不同口语任务时所使用的词汇短语的有显著差别,但是在一些要求较高的口语任务中,词汇短语的使用频率不高,说明中国学习者使用词汇短语的能力有待加强。(3)中国英语专业学生在口语过程中存在过多使用某些词汇短语的情况,特别是在交际口语任务中,某些词汇短语过多重复性使用的情况更加明显。同时还存在着某些词汇短语误用的情况。所有这些说明英语专业学生使用词汇短语的能力整体不高,有待加强。同时,研究者也发现词汇短语教学法对英语语言教学的进一步启示,揭示了词汇短语的教学的重要性,提出了词汇短语教学可行性的各种教学方法,例如:词汇短语辨别,词汇短语纠正等。
