USES OF THE PAST CONTINUOUS
We use the past continuous to talk about the past:
- for something which happened before and after another action:
 
The children were doing their homework when I got home.
Compare: The children did their homework when (= after) I got home.
This use of the past continuous is very common at the beginning of a story:
The other day I was waiting for a bus when …
Last week, as I was driving to work, …
- for something that happened before and after a specific time:
 
It was eight o'clock. I was writing a letter.
Compare: At eight o'clock I wrote (= started writing) some letters.
- to show that something continued for some time:
 
My head was aching.
Everyone was shouting.
- for something that happened again and again:
 
I was practising every day, three times a day.
They were meeting secretly after school.
They were always quarrelling.
- with verbs which show change or growth:
 
The children were growing up quickly.
Her English was improving.
