Explications:
Le prétérit est utilisé pour parler d'une action passée et terminée.
-Quand c'est une phrase affirmative, on ajoute "ed" à la fin du verbe (sauf pour les verbes irréguliers):
ex: knock -> knocked
look -> looked
buy -> bought (verbe irrégulier)
-Quand c'est une phrase interrogative, on utilise l'auxiliaire "did" et on fait:
Did + sujet + verbe
ex: Did she eat?
-Quand c'est une phrase négative, on utilise "didn't" (contraction de "did not") et on fait:
sujet + didn't + verbe
ex:
She didn't know
(On utilise pas "didn't" pour le verbe "be" puisque "be" peut se mettre sous sa forma négative: wasn't ou weren't)
-Quand au prétérit be + ing, il décrit action qui est en cours/pas finie dans le passé souvent interrompue par une action ou un évènement. On fait:
be (au prétérit) + verbe + ing
ex: You were sleeping when I arrived.
She was eating when you came.
-Pour une question, on inverse le sujet et l'auxiliaire "be".
ex: Were you sleeping when the phone rang ?
-Dans une phrase négative, on met l'auxiliaire "be" sous sa forme négative.
ex: I wasn't sleeping when the phone rang.
Voilà j'espère que ça t'aidera :)
