The Functional Features of Chunks in Journal Articles of Aquaculture

This study investigates the functional similarities and differences of four-word chunks in the academic discourse of aquaculture by Chinese and international scholars based on Hyland’s functional classification method within a corpus-driven approach. The findings reveal that, compared to their international counterparts, Chinese scholars significantly utilize more four-word chunks. Functionally, Chinese scholars frequently employ quantification, structure, framing, and engagement chunks, underscoring the importance they assign to the logic of discourse and the interaction between authors and readers. The infrequent use of description chunks suggests that it is essential for Chinese scholars to fully appreciate the significance of describing research objects, methods, and results in order to convey the foundational and experimental nature of hard science research. Furthermore, the structures of chunks used by Chinese and international scholars to express the same discourse functions differ. The expression of data indication among Chinese scholars appears more solidified. These research results can offer valuable references for academic writing.
