Прочитайте тексты и установите соответствие между текстами А– E и заголовками 1– 6. Запишите свои ответы в таблицу. Используйте каждую цифру только один раз. В задании есть один лишний заголовок. 1. Economy and industries 2. Food and drinks 3. Main cities 4. Leisure time 5. Population 6. Pages of history A. Australia once had close ties with Great Britain. Until fifty years ago, almost all Australians were of British or Irish origin. But after World War II more than two million people arrived from Europe. New Australians, as they were known, were from Greece, Germany and Italy. Mass migration has changed Australia into a multicultural society. Today, people of Anglo-Irish origin are a minority. Many recent immigrants are from South East Asia, the Philippines and China . B. Australia's prosperity has been founded on its natural resources. It produces almost every mineral from gold to uranium. Traditionally, Australia was a farming country and its wealth was founded on wool, cattle and wheat. It is still a major exporter of food, making it the breadbasket of Asia. Agriculture and mining, however, employ comparatively few people. Tourism is now Australia's largest industry, employing 6% of the population. More than three million visitors come to the country each year. C. In spite of the importance of the bush to Australian folklore, 90% of Australians live in cities. Almost everyone lives within a few kilometres of the sea and of the ocean. The beaches are used in same way as parks: families have picnics, people of all ages jog, play volleyball, swim or just walk. There is great interest in water sports like water skiing, surfing, swimming and sailing. Every city has tennis courts, allowing half a million people play competitively. D. The Dutch were the first Europeans to see Australia, in the early seventeenth century, but they found no opportunities to settle or trade. English explorer James Cook landed near Sydney 160 years later and claimed it for Britain. But still no one could think what to do with it. The American Revolution provided a solution. America had been used Australia as a dumping ground for criminals, mostly the unfortunate poor from cities created during the industrial revolution. E. Australians used to live on a diet of lamb and potatoes. But with such a variety of climates and with so many ethic groups, the Australian diet has changed dramatically. Cities like Melbourne and Sydney are proud of their huge range of ethnic restaurants and multicultural cuisine, ranging from Italian to Tibetan. The barbecue is a national institution. It is an informal event for people and there is nothing more refreshing than a swim before eating fruit, fresh salads, and steaks.
