Whose umbrella is this, Paul?
Are these caps yours, Peter?
The room is now clean and tidy.
The black socks are mine.
Where can 1 put the crayons?
—I will tidy them up, Mum.

— They are dirty. Please throw them away.

Look! This is Jack and Tom's bedroom. What a mess! They don't tidy up the room. There are two beds, one desk and two chairs. The blue chair is Jack's and the yellow chair is Tom's. Jack likes blue very much, but Tom likes yellow very much. They are twin brothers and they are in the same class. They go to school together every day. There are many things on the desk: books, schoolbags, pens, pencils, cups and many other things. The blue cup is Jack's. Whose yellow cup is that? Do you know? Yes, it's Tom's.
