Reading

Task 1. Read the article.

Holidays, Travel and Tourism

If I win the prize of 20,000 dollars, I will spend it in the world round trip.

My travel experience would begin in New York, known as one of the world's most modern cities because of its skyscrapers and its dynamic spirit. From New York I would cross the Atlantic Ocean to England. In London I would explore the British Museum and visit the shops and pubs along King's Road in Chelsea. My next stop would be Amsterdam, an attractive city because of its steep narrow houses and canals lined with trees. Flying on to Copenhagen I would eat Danish open-faced sandwiches and be entertained at night clubs in Tivoli Gardens. Having seen enough cities by this time I would head south to the Italian Riviera. Portofino, a handsome fishing village resembling an opera setting, is one of the most charming vacations sports in Europe. Of course, a serious traveller could not leave Italy without visiting Florence, Venice, Naples and Rome, for all these cities are living museums.

Continuing South, I would trace the beginning of Western civilization. I would make stops in Athens and Caria. Certainly a chance to see the pyramids should not be missed. Next, I would fly east to visit the shimmering island of Ceylon. Here, the traveller finds many precious gems for sale, but the brightest jewel of all is Ceylon itself. Leaving this island I would travel to Bangkok, an Oriental city of many charms. Then, like many other travellers, I would be drawn to Hong Kong, the shopper's paradise.
