One is based on the fact that negated event sentences accept durative complements (whereas their positive counterpart do not), this fact being taken as an argument in favour of the aspectual role of negation. Our answers are: first, some French data suggest that durative complements with negation should not always be seen as demonstrating the din'alive' ity of the predicate; second, Kamp and Reyl. s (1993) representation provides a satisfying way to account tbr such data. The second argument is based on examples ill which an anaphoric reference see, ms to be made to the denotation of negative sentences, therefore suggesting that they have one.

This dimension is introduced by discourse referents. Recall that DRT discourse referents do not serve only to account for this aspectual dimension, but do play a fundamental discursive role. Nevertheless, the categorisation into states (s) and events (e) of the utterances to bc represented, and the possible introduction of the discourse referents of one of these aspectual category, may be associated with the Asp head. This association gives us the expeeled result: the discourse referent e or s is in the scope (in the sense of DRS construction) of the possible negation.",

In constrast, discourse ret~rents are only present in the form of DR-variables; they will be introduced by the partial DRSs. The translation of noun phrases (NP) or determiners is quite close to that of the Montagovian tradition. A determiner is associated with a partial DRS, which is, so to speak, what remains of a DRS when one takes away a predicative DRS. As a consequence, there will be variables over predicative DRSs (PDRS-variables) in partial DRSs. A partial DRS can also contain a declared discom'se referent. This discourse referent is meant to serve as an argument of the predicative DRS which will be assigned to one PDRS-wxriable during the conversion.
