I was singing a song.
She was drinking tea.
They were watching the movie.
She was cleaning the house when the phone rang.
John was cooking dinner when he suddenly cut his finger.
Future Continuous
I will be working here.
He will be drinking tea with us.
We will be dancing all night.
I will be waiting for you here at 9 a.m. tomorrow
They will be watching the game when the rain starts.
