Past Continuous: The Background Tense
was/were + -ing paints the background scene of the past: what was happening when something else happened. The camera rolls, then the phone rings.
Past Continuous
The scene behind the story
The past continuous is a film camera: it records what was in progress at a past moment. Meanwhile, the past simple drops in as the interruptor — the thing that happened.

The Formula
was/were + verb-ing
The formula is the present continuous with the time machine: was or were plus the -ing verb. Negatives add not, questions swap the order.

Common Mistakes
Four camera slips
The camera fails when the -ing goes missing, when was and were swap places, or when a habit tries to film as a scene.
