The Negation of Action Sentences. Are there Negative Events?

Events have three properties: they have causes and effects, they need a time and space zone and they can happen. In his work, Davidson (1967, 1969) argues that events are necessary to provide a logical form for action sentences. We can then ask what happens when action sentences are negated: do they still refer to events? Native speakers often have the feeling that, when an action sentence is negated, it means that it refers to something that did not happened. Is it possible that an action sentence could describe something that is not happening? Or is it possible that a negative sentence could represent an action sentence and could therefore refer to an event?
