Past Continuous

The Past Continuous describes actions in progress at a specific moment in the past. Learn its form, uses with while/when, and contrast with Past Simple.

What is the Past Continuous?

The Past Continuous (also called the Past Progressive) describes actions or situations that were in progress at a specific moment in the past. It focuses on the duration and ongoing nature of a past activity, not its completion.

It says: "This was happening at that moment — the action was in the middle of taking place."

Core Uses

Use 1 — Action in progress at a specific past moment

The Past Continuous describes what was happening at a particular time in the past. It frames the background action.

At nine o'clock last night, I was watching a film.
\"What were you doing at 3 p.m. yesterday?\" \"I was in a meeting.\"
In 2015, she was studying medicine in London.
This time last year, we were living in a different city.

Use 2 — Interrupted action: background + interruption

The most common use at B1 level. A longer background action (Past Continuous) is interrupted by a shorter, sudden event (Past Simple).

Structure: was/were + -ing ... when + Past Simple

I was having a shower when the doorbell rang.
She was driving home when she saw the accident.
They were eating dinner when the lights went out.
He was sleeping when his alarm went off.

The Past Continuous = the longer, ongoing action
The Past Simple = the shorter, completed interruption

💡 Grammar note: When introduces the interruption (Past Simple). While introduces the background action (Past Continuous):
- I was reading while she was cooking.
- While I was reading, the phone rang.

Use 3 — Two parallel actions happening simultaneously

When two longer actions were both happening at the same time in the past, use Past Continuous for both.

Structure: was/were + -ing ... while ... was/were + -ing

He was reading the paper while she was making breakfast.
While* I was studying, my brother was playing video games.
The children
were sleeping while the parents were working* downstairs.

Use 4 — Setting the scene in narrative

Writers use the Past Continuous to establish the atmosphere and background of a story before the main events (Past Simple) begin.

It was raining heavily. The streets were flooding and pedestrians were running for shelter. Nobody expected what was about to happen.
The café was filling up. People were talking and laughing. Then suddenly, the door burst open.

Use 5 — Polite or tentative requests (spoken English)

The Past Continuous can make requests sound softer and less direct than the Present Continuous.

I was wondering if you could help me.
I was hoping you might be free this afternoon.
We were thinking of going out — would you like to join?

Real-World Examples

Explaining an interruption:

\"Sorry I missed your call. I was driving at the time.\"
\"We were just leaving when the rain started, so we decided to stay.

Asking about the past:

\"What were you doing this time yesterday?\"
