Starting from descriptions of French connectives (in particular "donc"---therefore), on the one hand, and aspectual properties of French tenses pass4 simple and imparfait on the other hand, we study in this paper how the two interact with respect to the expression of causality. It turns out that their interaction is not free. Some combinations are not acceptable, and we pro- pose an explanation for them. These results ap- ply straightforwardly to natural language gen- eration: given as input two events related by a cause relation, we can choose among vari- ous ways of presentation (the parameters being (i) the order, (ii) the connective, (iii) the tense) so that we are sure to express a cause relation, without generating either an incorrect discourse or an ambiguous one.
