自上世纪初,共现词语组合的研究已经引起了语言学家的注意。研究发现中国英语学习者使用词串的频率是本族语者的四倍,但中国英语学习者注重词串的语义层面,本族语者多注重其语用层面。本文通过对词串的研究,论述中国英语学习者在词串使用过程中存在的问题。 Since the early of last century, the research on co-occurrence word combinations has drawn the attention of linguists. The study found that Chinese English learners use the word frequency four times as often as native speakers, but Chinese EFL learners focus on the semantic aspect of the word string while native speakers pay more attention to their pragmatic level. Through the study of word strings, this article discusses the problems existing in the use of word strings by Chinese English learners.
