认知心理学基于信息处理模型提出了打破信息容量瓶颈的组块概念。语言学界借鉴这一概念,提出语言组块的理论,指出人类以语言组块的形式记忆和储存语言,从而扩大了对语言的记忆和存储容量。语块的大量使用是保证语言交际流利度的要素之一。本文对语块的各种定义、形式的分类及其特色进行了分析探讨,并提出将英语语块的研究成果运用于新一代英语学习词典的设计编纂和研究中。语块在形式上的整体性、结构上的生成性及对语境的依附性等三个重要特征对新型英语学习词典的收词立目、例证选取及提示说明的设置等均有重要的启示。 Cognitive psychology proposes the concept of chunks to break the bottleneck of information capacity based on the information processing model. Based on this concept, linguistics draws up the theory of linguistic chunks, pointing out that human beings use linguistic chunks to memorize and store languages, thus expanding the capacity of linguistic memory and storage. The extensive use of chunks is one of the essential elements to ensure the fluency of language communication. This paper analyzes and discusses the various definitions, forms and features of the block, and puts forward that the research results of English block should be used in the design compilation and research of the new generation of English learning dictionaries. The three important features of the block, such as formal integrity, structural formation and contextual dependency, have important implications for the new English learning dictionaries .
