Many cities suffer from smog. Vast forests are cut and burn in fire. Their disappearance upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.The pollution of air and the world’s ocean, destruction of the ozone layer is the result of man’s careless interaction with nature, a sign of ecological cities.

Welcome to London, the capital of Great Britain. There’s a lot to see in London. London has many beautiful old buildings and monuments. There are two famous addresses in London. One is 10 Downing Street, the Prime Minister’s residence. The other is in the very centre of London. It is Buckingham [bAkINqm] Palace. Let me tell you about Buckingham Palace, the Queen’s residence. Buckingham Palace is like a small town, with a police station, two post offices, a hospital, a bar, two sports clubs, a disco, a cinema, and a swimming pool. There are 600 rooms, three miles of red carpet, 300 clocks and 700 people working in the Palace.

Dear David,
How are you? Let me tell you about my life in London. I’m here at an English school. I’m in class 3 with five students. They’re from different places – Germany, Russia, Japan and Italy. Our English teacher is very good. His name is Peter Briscall. Look at my new address at the top of the letter. I’m with an English family, the Browns. Mr. and Mrs. Brown have three children. Thomas is fourteen, Catherine is twelve, and Andrew is seven. They are friendly, but it isn’t easy to understand them. London is big and interesting. Hyde Park, Green Park and St. James’ Park are in the centre. Love, Julia.
