词汇重复与英语篇章

借助Hoey(1991)的词汇模式分析方法，我们从教材中任选了一篇非叙事体英语篇章，进行分析．本文的目的试图说明词汇重复在教学篇章组织中的作用，即词汇的重复，特别是跨句重复，大大有助于教学篇章的连贯．我们通过统计分析发现，与上下文形成词汇重复关系多的句子在教学语篇中处于核心地位，反之处于次要地位．中心句和边缘句的判别可根据词汇重复相关的句子数目来判定，同时也可辨明主题控制句和主题结论句．从各句之间形成的词汇重复网络中，我们能大体摸清主题的发展轨迹，把此研究成果应用于英语教学实践中会起到至关重要的作用，给英语教师以更多的启示．

Lexical Repetition and English Text

By means of Hoey's (1991) approach to the analysis of lexis pattern in text, we analyze a non-narrative English text with long sentences chosen from our textbook. The paper tries to prove the functions of lexical repetition in text organization and its contribution to textual coherence. It is possible for our English teachers to get some implications from the study. Applying the findings in practice will be of significance in our English teaching.
