OSLO — Excited with pride, Norwegians sang in the streets of Oslo on Sunday, celebrating Norway’s National Day and the country’s Eurovision Song Contest victory.

Hundreds of Norwegians sang along to Alexander Rybak’s winning song Fairytale as they walked in the country’s traditional National Day parade (游行) celebrating the Norwegian constitution.

Alexander Rybak — called “Alexander the Great” by the Norwegian media — won a great victory in the Eurovision Song Contest (ESC) by gaining the most votes in its 53-year history in Moscow on Saturday.

Alexander has played violin and piano since he was five years old, and he also composes his own music and sings. In 2006 he won the Norwegian talent show Kjempesjansen with his own song Foolin. Alexander has performed with one of the world’s most celebrated violinists, Pinchas Zukerman, won the Anders Jahres Culture Price and has been the concertmaster for Norway’s largest symphony orchestra (交响乐队) for youths, Ung Symfoni.

Norwegian Prime Minister Jens Stoltenberg said there was clearly something special about the 23-year-old and his folk music. “This is a phenomenal performance by a young and talented musician,” Stoltenberg said in a statement.

Rybak is expected to draw a large crowd of fans to Oslo’s Gardermoen airport when he arrives next Sunday, after having invited all his countrymen from the stage in Moscow.

With Rybak’s win, Norway will host next year’s Eurovision finals, a show that reaches a television audience of over 100 million people. Norway’s Minister of Culture, Trond Giske, promised that Norway would put on a splendid show next year but without spending as much as Moscow, which spent 24 million euros this year. “I don’t think that is necessary,” he told national broadcaster NRK.

The win was Norway’s third. The Nordic country also won the Eurovision Song Contest in 1985 and 1995.

People in cities all over the world shop in supermarkets. Who decides what you buy in the supermarket? Do you decide? Does the supermarket decide?

When you enter the supermarket, you see shelves full of food. You walk in the aisles (走道) between the shelves. You push a shopping cart and put your food in it.

You probably hear soft, slow music as you walk along the aisles. This may be an attempt to please you, so you will enjoy shopping. Some supermarkets want to increase their profits by playing soft and slow music, because the slow music makes you walk slowly and you have more time to buy things.

Fresh fruit and vegetables are usually put near the entrance. When you arrive at the supermarket, you think about the kinds of fruit and vegetables you need first. Once you’ve got that out of the way, you can relax and do the rest of the shopping without any hurry. Besides, if you see fresh goods first, it gives you a “feel good” impression of freshness, so you can not help spending your money.

Maybe you go to the meat department then. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk past all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.

Most of the food in supermarkets is very attractive. It all says “Buy me quickly!” to the customers. The fresh fruit and vegetables say “Buy me quickly!” as you walk by. The expensive meat says “Buy me quickly!” The supermarket tells you what to buy.
