The Rhetorical Pre-Requisites of Teaching Expository Discourse
The article examines the structure of an expository utterance against the background of other modes of discourse. The paper gives a tentative classification of expository utterances, their structural peculiarities and relationship with the other modes, and comes up with a list of communicative and rhetorical skills essential to each type. The authors differentiate between the so-called nuclear (i.e. indispensable) skills and variable (optional) ones, depending on the communicative situation.
