ВОПРОСЫ
Which place...
1. consisted of states and territories for over a millennium? 2. can be called an icon of modern architecture?
3. consists of islands linked by bridges?
4. is as large as continent though it is a country in reality? 5. can be called a work of art?
ТЕКСТЫ
-A-JAPAN
The vast majority of the 127 mil lion population live on the crowded coastal plains of the main island of Honshu. The three other main islands are Hokkaido, Shikoku and Kyushu, and all are linked to Honshu by bridges and tunnels that are part of one of Japan's modern wonders.
-B- GERMANY
Germany has always been the problem child of Europe. For over a millennium it was no more than a loose confederation of separate states and territories, whose number at times topped the thousand mark.
-C- PARIS
The whole city is something of a work of art. Two thousand years of shaping and reshaping have resulted in monumental building, sweeping avenues, grand esplanades and celebrated bridges.
-D- NEW YORK CITY
The most beguiling city in the world, New York is an adrenaline-charged, history-laden place that holds immense romantic appeal for visitors. Wandering the streets here, you'll cut between buildings that are icons to the modern age. You really would have to be made of stone not to be moved by it all. There's no place quite like it.
-Е- LONDON
Ethnically London also Europe's most diverse metropolis: around two hundred languages are spoken within its confines, and more than thirty percent of the population is made up of first, second- and third- generation immigrants.
-F- BRAZIL
Brazilians often say they live in a continent rather than a country, and that's an excusable exaggeration. The journey from Recife in the east to the western border with Peru is longer than that from London to Moscow.
