A contrastive study of grammatical metaphors in abstracts of Chinese MA theses and expert academic writing

Abstract As a significant indicator of College students’ ability in academic English communication, academic papers, especially their condensed abstracts require various writing techniques among which the use of grammatical metaphors (GMs) is typical. To improve the English academic writing level of Chinese postgraduate students, it is significant to compare their use of GMs with that in expert research articles. On the basis of Halliday’s reclassification of GMs, this study aims to compare the characteristics of GMs in abstracts of MA theses and expert research articles (RAs). It is found that there is universal use of nearly all GM types in both groups. The two groups are similar in that they share the top five most frequently used GMs, and there are no significant differences in the use of more than half of the GM types. However, the overall GM frequency of expert RAs is significantly higher than that of MA theses. Significant differences are also found in the use of six GM types. Furthermore, some correlations between certain GM types found in expert RAs are missing in MA theses. Reasons for these differences may include the limited understanding of GM, the underdeveloped cognitive ability, the genre differences, and the first language differences. Based on these findings, implications for teaching and learning are discussed.
