22.I was writing a letter when you come
he was having breakfast when you called up
she was playing chess when entered the room
she was taking a music lesson when your friend called
they were discussing the new film when our neighbor knocked the door
you was having tea when when your friend come in
what did you when sister was coming in?
24.
we read this book last year
what they were doing when you come in?
i was reading a book while she was writing a letter to her sister
he never showed me his pictures
I got a telegram from him yesterday
John brought us two tickets for a football match last Sunday
who took my dictionary?
It won't take me long to get there
it goes to rain,so we won't go anywhere,but will stay at home
i will go down snow street,when I will hear somebody calling me
he has gone already
I went to see my parents last Sunday
theyhave come already
they had a lesson, when he came
