摘要
本文研究经济学术期刊论文中的词汇使用情况,研究涉及的语料是从经济学期刊中随机抽取的120篇文章,共有907,380个字符。研究结果表明"学术词表"在经济学术期刊论文中的覆盖率为12.74%,但分布不平衡。在选取的九个关键词的个案研究中,只有四个属于"学术词表"词汇,其余五个都是"通用词表"词汇;这些关键词与其他三个核心表达一起,在经济学术期刊论文中起到篇章与修辞的功能。
This paper reports a study into the use of lexical items in economics journal papers. The corpus in this study （EC） consisted of 907,380 running words from 120 journal papers randomly selected from economics journals which were written by native English speakers. The results showed that the Academic Word List （AWL） accounted for 12.74% of the tokens in EC and the distribution of AWL in EC was uneven. In the case study of the key words, only four out of nine key words ranked by keyness were AWL words, while the other five were from the General Service List （GSL）. Moreover, those nine key words together with other three key functional expressions were employed to fulfill discourse and rhetorical functions in academic writings. Pedagogical implications are also discussed within this paper.
