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)
If you go back to the time of Queen Elizabeth (1558–1603), people really knew how to eat and Chefs used to travel round Europe to get new ideas and ingredients. It was also the time when British explorers sailed all over the world. They brought home all sorts of exotic food: rice and tea from China, spices from India, coffee from Arabia. In the Americas they found tomatoes, potatoes, peanuts, pineapples, sugar and vanilla.
B)
In the past, without cookbooks and TV programmes, women learnt from their mothers and spend hours every day in the kitchen. But then, around the end of the 18th century, life in Britain changed dramatically. The industrial revolution took families from farms in the country to the crowded cities. Men and women worked long hours in the factories. So they had no longer time or energy to cook properly at home. There was already an interest in fast food.
C)
Every country seems to have a national cuisine and to be proud of it. So what is Britain famous for? The sad truth is that most of the British gave up cooking a long time ago and started buying ready-made meals from the shops. They love tins, tubes, packets and frozen food of all kinds. Of course, convenience food is an international phenomenon, but it started earlier and has gone further in Britain than in most countries.
D)
It’s more than just a tradition – it is a way of life. Many people have tea first with breakfast, then at mid-morning, with lunch, at tea-time (around 5 o’clock), with dinner, and finally just before bed. As a nation, they get through 185 million cups per day! Most British use tea bags these days, but serious tea lovers still go through an almost Japanese-style ceremony. The selection of tea is very personal.
E)
The country has some excellent food: lamb from Wales, shellfish and salmon from Northern Ireland, fresh fish from Scotland, cheeses from England and Wales. Unfortunately, good British food is difficult to find. Only 2% of restaurants in London serve British food. There are many more Italian, Chinese and Indian restaurants. You can have a good “British” meal without spending a lot of money by going to a pub (or public houses) that you can see everywhere in Britain.
