本文从语料库角度对中国学习者常易混用的tend和intend两词的使用状况进行了分析,基于索引行比较了两词的类连接、语义韵等扩展意义单位。结果发现,学习者在使用tend一词上与本族语者有显著差异,并且学习者两词的类联接形式也比较单一,对两词的语义韵概念模糊。在此基础上,文章探讨了索引行分析以及相关语料库技术在外语教学环节上的应用。 This paper analyzes the usage of tend and intend in Chinese learners from the perspective of corpus. Based on the indexed lines, this paper compares the extension of meaning units such as class concatenation and semantic rhyme. The result shows that learners have significant differences from native speakers in the use of tend, and learners also have a single class of conjunctions, which obscures the concept of semantic rhyme. On this basis, the article discusses the application of index line analysis and related corpus technology in foreign language teaching.
