This is Mary's notebook
The mason's tool is heavy
She prepared her children's outfit
The boy's coat was torn
Mr Van is Mr Dong's friend
The house's windows are green
The boys' caps are on the shelves
The pupils' desks are always clean
He likes to read John Keats's poems
My mother-in-law 's house is in the country
