3. Past continuous

The past continuous describes actions or events in a time before now, which began in the past and is still going on at the time of speaking. In other words, it expresses an unfinished or incomplete action in the past.

We use the past continuous to talk about:

to talk about an action in progress at specific moment in the past.

  • I was still sitting on the plane at twenty past twelve.

to refer to a past action interrupted by another action.

  • I was walking home when I saw them.
