The aim of the current study was to examine conjunctions in academic texts. The corpus included 200 conference abstracts, of which 100 were written by Iranian novice writers and 100 by English native speakers. Each group of texts consisted of 50 abstracts from soft sciences and 50 from hard sciences. Following Liu's (2008) taxonomy, the frequency and type of conjunctions were examined. The results revealed that non-native writers use more conjunctions in their conference abstracts. Furthermore, it was found that compared to hard sciences, more conjunctions are employed in soft sciences. Regarding the role of L1, the results showed that non-native writers in soft sciences are more likely to use conjunctions. Moreover, the findings indicated that the most frequent conjunction type used by both native and nonnative writers are adversatives and additives in soft sciences, and additives and adversatives in hard sciences, respectively. The findings of the study have implications for teaching academic writing and material development for writing courses.
