Te explico como lo hice:
Esas palabras que, como sabes, estan en preterito simple, siempre van a ir antes del sujeto.
Luego, para que no tenga un presente (Is, are y am) debes cambiarlo por were y was.
Esos, al igual que is, are y am, son del verbo To Be.
Para saber cambiarlo:
Are: were
is, am: was
Cualquier cosa que no entiendas te respondo con gusto (si es que se como responder tu pregunta).
SI te sientes mas segura con tu profesor/a, no hay problema!
De nada, ojala te haya ayudado.
