I. Read the passage and do the tasks that follow. ____________________________ Playing football on the beach, samba dancing at night, relaxing with a delicious ice-cold fruit juice in an outdoor café, meeting sociable, hospitable people: this is what I think of when I remember the beautiful city of Rio de Janeiro. ____________________________ Rio is called "The Marvellous City" for a good reason. It is in an extraordinary location in Guanabara Bay, surrounded by spectacular mountains and by impressive sandy beaches facing south onto the Atlantic. The views almost everywhere in the city are breathtaking. ____________________________ There is something to do in Rio 24/7. In the morning, you can visit the centre with its museums and picturesque, historic churches or go up Mount Christ with Corcovado to see the eye-catching statue of Christ with its stunning views. In the afternoon, you can relax on the beach and watch the world go by or join in a football game with the welcoming, good-natured locals. Or you can go to the striking Maracana Stadium to watch the professionals play. At night, there is music and dancing everywhere. Even if you are not a brilliant samba dancer, you will have an amazing time. ____________________________ Of course, Rio does have problems. There are enormous areas of depressing slums on the hills around the city and violent crime can be a problem, though the situation has improved recently. However, for me Rio is one of the most fascinating places in the world and Cariocas the warmest people, so I cannot wait to go back!

City Life or Country Life? Which place is the better - the city or the country? Two American teenagers talk about where they live. Leo, 16: I live in New York and it’s great. There are huge shopping centres and interesting places to go. My mum loves all the art galleries and museums, but I like Central Park where I go skateboarding. It's big enough to get away from the noise and traffic. The country isn't for me. It isn’t exciting enough for people of my age. Most people don't live close enough to their friends to have enough a good social life. It's too quiet and too boring. City life is the best. Amelie, 14: I live on a ranch in the country, in Colorado. In the summer, we go hiking in the mountains, and in the winter I go snowboarding. I really like it because it's relaxing and quiet. I can’t imagine life in the city. It isn't safe enough to walk around alone and it’s too dangerous to cycle in the streets because of the traffic. Overall, I think the city is too noisy, too dirty, too crowded and too expensive. I prefer country life!
