词块与外语学习者语言输出质量关系的实证研究

An Empirical Study of the Relationship between Lexical Chunks and EFL Learners' Quality of Language Output

词块能够促进外语学习者语言输出质量的提高,不同类型的词块对外语学习者语言输出的质量提高起到不同的促进作用,首先是句子构建者,其次是聚合短语、约定俗成的表达形式,最后是限制性结构短语。词块对不同水平的外语学习者也起到不同的促进作用,对语言水平相对高些的学习者所起促进作用相对大些,而对语言水平相对低些的学习者的作用相对小些。

Lexical chunks can facilitate the quality of language output by the EFL learners, and different types of lexical chunks have different effects on it, among which sentence builders contribute most, with polywords, institutionalized expressions, and phrasal constraints placed in the sequential order. Also, lexical chunks contribute distinctly to the EFL learners with varied levels of English, improving more to the learners of relatively higher level, and less to the learners of relatively lower level.
