aka Past Continuous
The English past progressive indicates that something was in progress or continued for a time in the past and ended before another reference point in the past. It is conjugated with was or were plus the present participle.
The past progressive is used
- to express an action that was ongonig when another action interrupted it:
- While we were having dinner, the doorbell rang.
Note the use of two different past tenses: the continuous, background action of having dinner (in the past progressive) and the one-time action - the doorbell ringing - interrupting it (in the simple past).
- for multiple actions occurring at the same time:
- While I was watching TV, my wife was reading her book.
- While I was watching TV, my wife was reading her book.
- as the only verb in a sentence referring to a continuing action at a point in time or during a period of time:
- What were you doing at 9pm last night? I was having dinner.
- I was sleeping from midnight until 7am.
- in if-clauses of conditional sentences using would, where the present state or action is unreal:
- I would be happier if I were losing weight.
- I would be happier if I were losing weight.
- in indirect speech, to refer to future planned events in the past:
- When we told James that we were going to the party next Saturday, he just laughed.
