This paper focuses on a theory of tense and aspect (the representation of time in natural language) that attempts a formM representation of the relevant lilt- guistic devices as implication rules in first order logic. It presents a rich ontology as far as verb aspect is concerned, distinguishing between complex patterns and vagueness. Examples and conclusions are drawn from tile com- parison between English and Portuguese, pinpointing the importance of contrastive studies both for the un- derstanding and for the evaluation of a general theory of tense and aspect. In the paper, we present the actual translations of a wide range of phenomena, and a short example.
