Past continuous =I was workingPast simple =I worked
Choice of emphasis
Often there is little difference between the past continuous and the past simple, except that the past continuous suggests that the event(s) were in progress at a time in the past or that they were happening as background or temporary events. Whether we choose to use the past continuous or past simple often depends on how we see the past event(s).
| Past continuous: writer chooses to show the events as ongoing at that time in the past. |
| Past simple: writer chooses to show the events as finished. |
Events in progress in the past
We use the past continuous to talk about events and temporary states that were in progress around a certain time in the past. We use the past simple to talk about events, states or habits at definite times in the past.
| The past continuous emphasises the action or event in progress around a time in the past. The event (working) was in progress at 4 pm. The event was not completed at that time. |
| The past simple emphasises the event that happened at a definite time in the past. The focus is not on events in progress but rather on the whole events (finished work, went home). The events were completed at that time. |
Emphasising main events with the past simple
When one event is more important than the other in the past, we can use the past simple to emphasise the main event. We can use the past continuous for the background event (the less important one):
[background event]Iwas listening tothe radiowhen[main event]Helenphoned.
[background event]Iwas sittingin the parkand suddenly[main event]Isawan old school friend I hadn’t seen for 30 years.
