The children did their homework. and The children did their homework when I got home.  As I was watching television the telephone rang.  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 …

 to show that something continued for some time:  My head was aching. Everyone was shouting.  for something that was happening again and again:  I was practising every day, three times a day. They were meeting secretly after school. They were always quarrelling.

 Use the past continuous to refer to an action in progress in the past. Use the past simple to refer to an action that interrupted the one in progress:  Mark was working on the computer when his boss called.  Mom was cooking dinner when I got home from school.

 Use the past continuous to set a background action. Use the past simple for an action that happened at one particular moment:  As they were approaching the Earth four of the spaceships caught fire.

 Usually use WHEN with the past simple and WHILE with the past continuous:  I was doing my homework when the lights went off.  While I was doing my homework the lights went off.

 What is the difference between when and while? WHILE: Usually we use while when there are two long actions.  WHEN: Usually we use when if one action is long and the other is short. We use when if there are two short actions. We use when if we talk about periods of our life (When I was 12 …)
