2)Where were you when it was raining?
3)The telephone rang while/when I was sleeping.

6)I was doing my exercises, the electricity went off/ power cut.
7)My mother was cooking in the kitchen when I got up.
8)Was there anyone (who was )talking when the teacher entered the class room?
9)When the teacher was teaching, there were a lot of pupils told one another.
