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?
