Recently the Bologna process has promoted mobility programs for students, endorsing the use of English at university. Nowadays, many non-English universities implement programs, creating a forum for national and international students. This situation requires that non-native lecturers master not only the discipline but also the language and the rhetoric of English lectures. Additionally, non- native students attending programs in English speaking universities face a similar situation, where language is not enough but they need to know this academic genre. This book adopts a multidisciplinary theoretical approach, drawn on sociolinguistics, linguistics, and literary studies, to describe the rhetoric of lectures; specifically the use lecturers make of narratives in the classroom. A cross-disciplinary exploration in five academic disciplines sheds some light on the types of narratives, the narrative function, the narrative structure, and the linguistic features that articulate narratives in the lecture. Findings presented in this book will find a pedagogical application in EAP training courses for lecturers and students.
