【摘要】 本文以Levelt (1989)言语产出模式和Anderson (1983)的认知技能发展模式为理论基础,探讨中国非英语专业大学生词块的使用与二语口语流利性发展的相关性。本研究以实验为基础,采用横断法,通过看图讲故事诱发口语产出。作者详细分析了高、中、低三个语言水平的30名非英语专业二语学习者的言语样本,考察了不同语言水平学习者的口语流利性发展与词块的使用情况。两种变量的数据通过SPSS 11.5软件进行分析。得出以下结论: 1.词块的使用与非英语专业大学生二语口语流利性呈显著正相关。显示出词块的使用可以预示二语口语流利性。2.口语产出词块的数量不随语言水平的提高而显著增长。从初级到中级阶段,有显著增长,然而从中级到高级阶段增长缓慢。甚至出现高原现象。说明二语口语流利性的发展不是一个持续的过程。同时也证实了二语学习者接受性词汇大于产出性词汇。3.不同种类的词块对促进二语口语流利发展的程度不同。只有句子框架和聚合短语的使用能显著提高二语口语流利性。特别是句子框架的使用能全面提高二语口语流利性。本研究揭示了中国非英语专业大学生在课堂教学环境下二语口语流利性发展的趋势;证实了词块的使用能显著提高二语口语流利性;是从语言特征探索二语口语流利性发展的一次尝试;并且为发展二语口语流利度的大学英语教学模式提供了借鉴。更多还原

【Abstract】 Based on Levelt’s (1989) Model of Speech Production and Anderson’s ACT Model(1983), the present empirical study adopts a developmental approach, explores the correlation between the use of lexical chunks and the development of L2 oral fluency by eliciting the oral production from a picture-story narration. 30 speech samples from three English proficiency groups of Chinese non-English majors are examined in detail in order to see the development of oral fluency of these learners and their use of lexical chunks as well. Data analyses on the two variables are done by SPSS 11.5.Three major findings are stated as follows:The first finding shows that there is a moderate-to-strong, positive correlation between the use of lexical chunks and the development of L2 oral fluency. This suggests that the use of lexical chunks may serve as a predictor for measuring L2 oral fluency.The second finding shows that the number of chunks produced in speech does not increase significantly along with the progress of L2 proficiency level. There is a significant increase from the Elementary level to the Intermediate level, but no significant increase from the Intermediate level to the Advanced level, even plateau effect is found, which shows that the development of L2 oral fluency is not a continuous process. This finding also shows that L2 learners’receptive vocabulary is larger than their productive vocabulary.The third finding shows that only the use of sentence builders and polywords contributes significantly to L2 oral fluency, especially the use of sentence builders facilitates L2 oral fluency in all aspects.The study reveals the tendency of the development of L2 oral fluency for Chinese non-English majors in the classroom setting and the evidence proves that the use of lexical chunks facilitates L2 oral fluency significantly. It is an attempt to explore linguistic features of oral fluency. It opens up the possibility of altering present College English teaching and provides the momentum to reach English fluency.更多还原
