I have some questions with the clarification for the use of PENDANT.
As I have read in other grammar lessons, PENDANT is used to express the 'full duration' of a completed action IN THE PAST ... or the 'set duration' of an action to be done in the future. Pendant cannot be used for the present!
If this is the case then
a) would it help in clarification if some wording to that effect be added to the lesson for PENDANT, else based on the lesson someone could ask me "why cant I go into the kindergarten room? and I could answer " Les enfants dorment pendant une heure" ... which would be wrong...
b)the example sentence "Il court pendant une heure tous les matins/He runs for one hour every morning appears to be unnecessarily skirting that rule .. or at least adding a bit of doubt??.
Of course if there is no such restrictions please let me know.
