Прочитайте тексты и установите соответствие между текстами А–G и заголовками 1–8. Запишите свои ответы в таблицу. Используйте каждую цифру только один раз. В задании есть один лишний заголовок.

A)
The island of Ireland is bounded to the north and west by the Atlantic Ocean, the east coast is washed by the Irish Sea. The western landscape mostly consists of cliffs, hills and mountains. The country's interior is relatively flat, traversed by rivers such as the River Shanon and numerous lakes. Agriculture and food is an important industry in Ireland, with about 64% of the total land area used for agriculture. The main cities are Dublin, Cork and Limerick.

B)
Ireland has always been an agricultural country. It is almost self-sufficient in food and a major exporter. High technology industries have now made Ireland into Europe's largest (and the world second largest) exporter of computer software. American companies like Apple and Intel have invested heavily in Irish computer factories. The secret of Ireland's success is a young and highly educated population, who speak English. Now Dublin, the capital of the country, is an important world financial centre.

C)
Saint Patrick is the patron saint of Ireland and his day is celebrated on the 17th March with parades, "wearing of the green," music and songs, Irish food and drink, and activities for kids such as crafts, coloring and games. It's a time for fun. On that day almost every town has a parade of bands and floats. Some floats depict scenes from Irish history, others advertise products. The largest parade is held in Dublin.

D)
The Celts were the first known inhabitants of the island. They gave the Irish the basis of their language and culture. Saint Patrick, the patron saint of Ireland, is said to have brought Christianity to the Celts. Later, the Vikings arrived from Scandinavia and founded Ireland's two main cities, Dublin and Cork. At the beginning of the seventeenth century the British started an invasion on Ireland. They imposed their language and laws.

E)
It was imposed on the people of Ireland, yet it has produced some of the most imaginative writers of English literature. This creativity goes back the Gaelic poetry of the Celts. Irish is still the official language of Ireland, but the great majority of people speak English. Most television programmes are in English too. As a result of immigration, Polish is one of the most widely spoken languages in Ireland after English and Irish.
