Утвердительное: I was playing. We were playing. You were playing. They were playing. He / she / it was playing.
Вопросительное: Was I playing? Were you playing? Was he / she / it playing? Were they playing?

Отрицательное: I was not playing. We/ you/ they were not playing. He / she / it was not playing.

Для того, чтобы поставить глагол в форму Past Continuous, нужен вспомогательный глагол to be в прошедшем времени и причастие настоящего времени (Participle I) смыслового глагола.

To be в прошедшем времени имеет две формы:

was – 1 и 3 лицо ед. ч. (I was playing. He was eating.)
were – 2 лицо ед. ч. и все формы мн. ч. (They were playing.)
