There is a ghost in this room
There is an apple on the desk. 
There is oil on the pavement. 
There is a worm in this apple
There is a guitar in my room

There are 600 students in this school 
There are four windows in my room 
There are some windows in my room 
There are five dogs in the house
There are two chairs in my room


There is :
- my son
- the green house
- a pretty kitty
- an apple
- my car

There are :
- my friends
- the kids
- the students
