I have just come back
we have never been
she has just woken up
they have already had
has just washed
has cleaned
I have just made
has already painted
has taken
have just listened
have just gone away
has already answered
I have read
haven't seen
hasn't eaten
has just cleaned
they have had
have met
has missed
hasn't done
have they missed the last train lately
has Liz made a speech this evening
have children decorated the room this morning
has he just come home
has she swept the floor today?
have they danced in the next room
