轮机英语中的篇际词汇重复率

论文摘要

篇际词汇重复率是影响英语词汇习得的一个重要因素,它直接影响到词汇及其语法、句法、语义、词法的习得程度。本文以一百万字的轮机英语语料库为基础,在大量的统计计算和程序运行的支持下,着重研究了轮机英语中的篇际词汇重复率及其分布的特点,并分析了其对轮机英语词汇教学及学习的影响。 研究数据结果表明,在轮机英语语料库中,将近一半左右的词汇的篇际重复率为零,同时任意两篇文本的词汇重复率相对也比较低。在不同语篇中,重复五到十五次的词汇在整个语料库中所占的比率相当小,而在这些词汇中又有很大一部分是高频词、数字和人名。这给轮机英语学习者的词汇习得造成很大的困难。 篇际词汇重复率过低是轮机英语学习者在词汇习得和阅读理解方面出现障碍的主要因素,因此英语教师和教材编撰者应该找出方法,提高轮机英语词汇重复率,从而可以帮助提高对单词的认识理解程度,降低遗忘率。
