Даю 35 баллов срочно помогите мне пожалуйста умоляю!!!!!! Установите соответствие между текстами и их темами, выбрав тему из выпадающего списка. Используйте каждую тему только один раз. В задании одна тема лишняя. 1. Channel champion. 2. Parents. 3. Unhealthy eating habits. 4. Eat out. 5. Nature sights. 6. Places to visit. А.Most teenagers get along with their parents quite well. Although a lot of teenagers believe their parents are too strict, most agree that their parents offer help and support in times of crisis. When there are arguments, however, they are usually about what time they should come home at night, where they are going, and who they are going with. B. 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. C. Thirteen-year-old Thomas Gregory from London is the youngest person to swim the English Channel. He swam 31 miles in just 11 hours 55 minutes. He drank hot tomato soup because he felt so cold in the water. Often he could not see anything because the sun was shining in his eyes, and that was the worst thing. He was very pleased when he finally arrived on the beach in France, where his parents were waiting for him. D. Over 5,800 different restaurants and cuisine from more than 60 different countries await you in Britain’s capital. Come to London and eat your great meal from all the best cuisines all around the world! The experience of eating out in London is reaching new heights, with restaurants opening every week and some of the best-known names in cuisine to work here. E. Traditional methods of cooking and eating are disappearing, and are being replaced by fast food and ready-prepared meals. As a result, people today (especially children) have too much sugar, too many sweet drinks, too much white bread. This makes people’s level of blood glucose go up, causing tiredness, nervousness and headaches. Among schoolchildren it can also cause low concentration and bad behaviour.
