а) 15,2 × 8 + 73 × 6 = 121,6 + 438 = 559,6

Установите соответствие между текстами A–E и их темами, выбрав тему 1–6 из списка.

Используйте каждую тему только один раз. В задании одна тема лишняя.

This text deals with …

1) city attractions.

2) a London cinema.

3) a London theatre.

4) a London street.

5) nature sights.

6) a London museum.

A) The Lake District, in northwest England, is a small area, but extremely beautiful, with the

varied delights of soft hills and woodland and the panoramas of the great lakes. The Lake

District is more often visited, both by day tourists and holidaymakers, than any other region of

outstanding natural beauty in the British Isles.

B) England's most ancient northern city lies on the River Ouse in the centre of the Vale of York

between the Yorkshire Dales and the North York Moors. It was once the principal town of

Yorkshire, and it remains the seat of the Archbishop of York. A child-friendly city, its Viking,

Castle and Railway museums have plenty to engage young people as well as adults.

C) Along the north part of Trafalgar Square is the famous National Gallery. Founded in 1824, the

gallery has since grown into one of the most outstanding and comprehensive collections in the

world, with a list of masters ranging from Leonardo da Vinci and Rembrandt to El Greco and

Van Gogh.

D) The London Coliseum famous for its richly decorated interiors was used for variety shows,

musical comedies, and stage plays for many years. In 1974 its name was changed to

the English National Opera. Today it is used primarily for opera as well as being the London

home of the English National Ballet. When not on tour they perform regular seasons

throughout the year.

E) The Mall is London's impressive ceremonial way, a broad tree-lined avenue. The spectacular

parade takes place here each June to celebrate the official Birthday of the Sovereign. Queen

Elizabeth II rides down the avenue in a horse-drawn carriage. Over 1,000 officers and men are

on parade, together with two hundred horses; over two hundred musicians march and play as

one.
