    • was chopping

    • was driving
    • drove

  6. I was reading in bed ___ the doorbell suddenly rang.

    • when
    • while
    • as
    Show answer

    when

    'When' introduces the sudden interrupting event in past simple.

  7. An unexpected visitor

    Last Saturday I {1} a film alone at home when something strange happened. My parents {2} away for the weekend, so the house was unusually quiet. I {3} on the sofa with a cup of tea, and the only sound came from the TV. Suddenly, I {4} a soft noise coming from the kitchen. I paused the film and listened carefully. While I {5} slowly towards the kitchen door, my cat {6} past me and gave me the fright of my life. I {7} a complete fool, of course — but I'm glad I {8} the door behind me before he could escape into the street.

    • was watching
    • were
    • was sitting
    • heard
    • was walking
    • ran
    • felt
    • closed
    Show answer

    1. was watching — Past continuous for the long ongoing action interrupted by the strange event.

    2. were — Past simple of 'be' for a state — 'My parents were away'.

    3. was sitting — Past continuous for a background action — describing the scene.

    4. heard — Past simple for the sudden short event that interrupts the background.

    5. was walking — Past continuous after 'while' for the ongoing action.

    6. ran — Past simple for the sudden short event that interrupts the walking.

    7. felt — Past simple — and 'feel' as a state of being a fool is more naturally simple than continuous.

    8. closed — Past simple for a completed action — 'I closed the door'.

The Past Continuous as the Interrupted Action

The past continuous describes an action already under way at a particular past moment. Interruption is the context where this is easiest to see: something is in progress, and a shorter event cuts across it. The action in progress is the one that takes was/were + -ing.

I was waiting for the bus when I saw the accident. (waiting was already under way)
She was cooking dinner when the power went out.
They were driving home when the storm started.

Which Action Gets the Continuous?

Ask which action had duration — which one you could have been in the middle of. Waiting, cooking and driving all stretch over time, so they take the continuous. Seeing, going out and starting are instant, so they do not.

Background, Not Just Interruption

The same form sets a scene even when nothing interrupts it: The sun was shining and the birds were singing. Interruption is one use of the past continuous, not its definition — the constant is that the action is viewed from inside, while it was still going on.

Common Mistakes

✗ I waited for the bus when I saw the accident. → ✓ I was waiting for the bus...
✗ She was seeing the accident while she waited. → ✓ She saw the accident... (instant event)
✗ When the power went out, she was starting to cook. → ✓ ...she was cooking. (already under way, not beginning)
