中美大学生口语中词块使用特点对比分析

A contrastive analysis of chunks in the monologues by Chinese and American college students

本研究基于中国英语专业大学生的4年跟踪口语语料和美国大学生的口语语料，从流利性、准确性和多样性3项指标出发，对比分析中美大学生口头独白中词块的使用特点。研究结果表明：中关大学生口语中的词块使用异同并存；中国学生随着语言水平提高，词块使用的流利性、准确性和多样性均有所发展，越来越接近本族语者使用规范，但在准确性上仍有待提高；美国学生口头独白中的词块使用呈现较强的口语特征，表达更加自然、贴切。本研究结果对二语词块习得和口语教学具有启示意义。

Based on the monologues by 56 Chinese English majors in their first year and fourth year and 15 American college students, this paper makes a contrastive analysis of chunk features in terms of frequency, accuracy and variation. The results indicate that there are both similarities and differences in the use of chunks by the Chinese EFL learners and the native speakers; the Chinese learners have made real progress in their speech over three years; despite their near-native language competence, accuracy still remains a problem for the Chinese learners; comparatively speaking, the American students show a much stronger sense of chunk choice with respect to the pragmatic features, such as appropriateness and politeness. The findings contain some pedagogical implications for second language chunk acquisition and oral English instruction.
