en faite pour faire ton exercice, tu dois utiliser la règle be+ing AU PASSE
la différence est que au lieu de mettre am/are/is/it/are/are/are +BV+ING, tu vas mettre was/were/was/was/was/were/were/were .
Exemple:
1) We was having
2)Was writing
3)I jumped when i was hearing
4)last weekend I was playing
5)What were you doing
6)were you sleep
7)Yesterday, Mrs Mills was writing
8)When the dog was barking
9)They were seeing
10)she was watching
