Am I doing my homework? Is Jeff eating an orange? Is the women talking in the kitchen? Is Maria sleeping? Are the girls riding bicycles?
Are you eating an orange? Are they dancing? Are they doing their homework? Is father reading a book? Is he watching tv?
The boys aren't playing with the car. Pat isn't wearing hat. The teacher isn't talking to mrs Morton. The men aren't riding bicycles. The girl isn't eating a banana.
