The principal uses of the present continuous are listed below.
- To set the "background scene" to an event or action. We use the past continuous to describe the background scene and the past simple to describe the event or action:
- I saw him at 8 o'clock on Monday morning while he was waiting for the school bus.
- I was shopping in a supermarket when I noticed a strange-looking man.
- We may have more than one background scene happening concurrently:
- I was lying on my bed and listening to one of my favorite songs.
- To emphasize activities which continued for some time but whose exact limits are not known and are not important. Notice the important difference between these two sentences:
- For a while last year I was playing football for my local team and teaching English in the local elementary schools. (It doesn't indicate whether the actions were completed or not, or whether they happened concurrently)
- Last year I played football for my local team and taught English in the local elementary schools. (It indicates that all of the actions are now complete, and probabley happened in that order)
- Note: state verbs cannot be used in any continuous tense.
