Translation:An owl found mice in the stable.
Thank you, Sitesurf. I find this confusing. As a practical matter would it be fair to say for translating from English into French that the French use either the imperfect or the passe compose (or pluperfect) for past actions rather than the passe simple? Put another way, when do they use the passe simple?
The French passé simple is the exact equivalent of the English past simple. Unfortunately, it is rather difficult to conjugate and has been replaced with the passé composé (which has other uses as well).
Since you only find the passé simple in (well written) books, papers and magazines, and most of the time only in 3rd person singular and plural, Duo decided to not teach or use it on the courses from and to French.
The owl found mice in the stable = le hibou trouva des souris dans l'écurie.
