Written in French, this work reports the results of a longitudinal study of past-time reference in the interlanguages of four Swedish learners of French. Unlike most previous studies of L2 acquisition of temporal expression, which have focused on early interlanguage, Kihlstedt shifts the focus of inquiry in this study to the oral production of advanced L2 learners. Kihlstedt discusses evidence supporting a modified interpretation of Andersen's (1991) developmental stages in past temporal expression and proposes an ordering of aspectual value assignment to the passé composé and imparfait constructions in Swedish-French interlanguage.
