Event semantics and discourse

Event semantics is a popular approach to the analysis of sentences of natural languages which describe actions or events. According to it these sentences should be analyzed as those which predicates contain terms referring to events even though the sentences do not use such terms explicitly. But how licensed we are to assign such references to sentences which do not explicitly use terms for actions or events, and use only those for agents, objects and some other properties of what they describe? There are different arguments pro et contra, neither seems to be decisive. The hypothesis is that event semantics is just one of the context-sensitive strategies of interpretation, effective only when applied to the utterance of a sentence in a proper discursive context.
