1/ My wall-unit which I bought two days ago is very convenient.
Wall-unit standing in the living room is brown but in the kitchen there is white one.
We dodn't want to buy a new wall-unit.

Two new cushions bought yesterday are in the bedroom.
"Put the cushion on the bed!" - said mother angry.

The ceiling of the kitchen is painted every year.
We have to paint the ceiling of the kitchen every year.
4/ We have to bring an old stand-hall to our new flat.
