Although there is an extensive body of research concerned with anaphora resolution (. (Fox, 1987; Grosz et al., 1995)), event anaphora has been widely neglected. This paper describes the results of an empirical study regarding event reference. The experiment investigated event anaphora in narrative discourse via a sentence completion task. The results of the experiment suggest that the discourse structure established by an explanation or elaboration relation has an influence on whether the last mentioned event, previously mentioned events or a complex event is preferably referred to. .
