Comparative Study of Conclusion Section of Aerospace Research Article (RA) in the Use of Interactional Metadiscourse

This study provides a comparative corpus-based analysis of interactional metadiscourse between Chinese scholars and English native speakers’ conclusion section of aerospace research articles. For this purpose, based on Hyland’s (2005) interactional metadiscourse taxonomy, 52 aerospace conclusions writing pieces from two high-profile journals were selected for analysis. Results indicate that the discrepancy in total number and frequency lies in the use of hedges, boosters, and attitude markers. Linguistic features, sociocultural factors, and rhetoric functions are responsible for these discrepancies. This work may shed lights on academic writing and pedagogy.
