I (was having) lunch when my friend came. I (was playing) a computer game when mother came.
When the doorbell rang,I was (listening) to music.
I (was speaking) on the phone when you turned up.
When father came, I was doing my homework
I (was sitting) on the bench in the park when the car crashed.
When the light went off I was (watching) TV.
