Questions about the Imperfect
Q: Why is it (yo) nací en noviembre and NOT (yo) era nacido en noviembre
Remember, the imperfect describes a past situation, not a an event that happened once. Being born is an event that happened at a specific point in time which is described by the preterite; it is not a situation. It would, however, make sense to write: Cuando nací, mi padre trabajaba en Madrid.
Q: Why is it Ella comía durante el partido and NOT Ella comer durante el partido?
The infinitive (comer) cannot follow a subject. If there is a subject, the verb must be conjugated to agree with it. Since the meaning is "was eating", use the imperfect of comer here.
