What were you doing 
while Bob was playing 
the guitar?

What were you doing 
yesterday at half past 
five?

What was he doing 
when you saw him?

Was it raining when you 
looked out of the 
window?

Why was she crying 
when you saw her?

Were they watching TV 
when you got back 
home?

Who was she talking to 
when you saw her?

Who was he walking 
with when you met him?

When I first met her she 
was working in a 
restaurant.

Were you reading a 
book yesterday at five?

Were they kissing when 
you saw them?

Was I driving my car 
when you saw me?

Was John watching TV 
when the doorbell rang?

Why wasn't she listening 
to her teacher?

Why weren't they 
working when the boss 
came?
