after "il faut que" subjonctif passé

Question

can't ı say that "Il faut qu’elle soit partie avant midi."= she must have finished your homework...
title of the lesson is "Il faut que is always followed by Le Subjonctif Présent"
I think it must be uncorrect

Accepted Answer

Hi Ozan,
The expression être parti/e  (to be gone) is a passive form of partir so it is a present and not a past.
I would translate the sentence as -
She has to be gone before midday = Il faut qu'elle soit partie avant midi 
(subjunctive present of être)
different from the active form of the verb, to go which is partir.
She has to go = Il faut qu'elle parte ( subjunctive present of partir)
Bonne Continuation!
