THERE IS NO PLACE LIRE HOME
A
A lot of English families have got their own houses, but some peo ple live in flats. There are two floors in the traditional English house: the ground floor and the first floor. People in England like their homes and always show them to their visitors.
***
On Saturday Mr Blake invites Mr Voronin to his place to spend an evening with his family.
The Blakes1 live in a house with a garden not far from London. There is a sitting room and a study downstairs. The kitchen is down stairs too. The sitting room is large and sunny. There is a sofa, two armchairs and a coffee table there. There is a standard lamp and a TV set there too. Above the sofa there is a nice wall lamp.
Beautiful plants make the room cosy.
In the kitchen there is an electric cooker, a refrigerator-freezerand a washing machine, but there isn’t a dishwasher. There are also some cupboards with plates, cups, glasses, knives, forks and spoons.The study is a small room with bookshelves on the walls. Upstairs there are 3 bedrooms and a bathroom.
The Blakes love their house and think: “There is no place like home”2.
