基于语料库的学生英语形容词搭配语义特征探究

A Corpus-Based Study of Semantic Characteristics of Adjective Collocations in CLEC

本文通过对比中国英语学习者和本族语者在形容词搭配方面的不同模式,从语义角度探析学习者在形容词搭配使用中的典型特征。研究采用计算Z值和MI值的统计方法来确定搭配词共现的显著程度,数据来源于中国学习者英语语料库和本族语语料库。研究结果表明,学习者在形容词搭配方面和本族语者的使用惯例之间有显著差异,可以归纳为三个特征:搭配词选词不确切;多义词语义混淆;语义韵不和谐。本研究进一步探索了学习者搭配能力欠缺的原因,即母语干扰和基于交际策略的错误。并针对该问题提出解决方法,即在语言教学中引入索引工具,向学习者提供优质充足的输入材料。

This paper compares the adjective collocational patterns of Chinese-speaking learners of English with those of native speakers of English on the basis of corpus data. A learner corpus ( CLEC) and English corpora of native speakers (LOB, JDEST, and COBUILD) were employed along with the concordance softwares MicroConcord and WordSmith. Besides, the statistical methods of Z-score and MI-value were adopted to measure the significance of the co-occurrence of collocates. A great discrepancy was found between Chinese learners' use of adjective collocations and the conventional use by native speakers. Evidence in this study points to three major characteristics of Chinese learners' use of adjective collocations: semantic imprecision in the use of collocates, semantic confusion of polysemous adjectives, and semantic inharmony.
