Task 1. Read and choose the correct item.

George, Athens
The majority of annual visitors to Greece arrive on package tours to the Greek islands and rarely get the opportunity to explore the sights of Athens, which is a pity because despite the noise and traffic jams, it is one of the most exciting and fascinating cities in Europe. To make sure you get to see the most important sights, you can book a city tour at a very reasonable price. However, it is always wise to pre-book tours of Athens, especially if you are going to come in August. There is a wealth of scenery to enjoy in the surrounding countryside, too, so try to take in other one-day excursions out of the city. At the heart of the city, nestled at the foot of the Acropolis, is the Plaka, the oldest and most picturesque neighbourhood in Athens. Overlooked by the glorious temple of the Parthenon, it is a maze of narrow streets running in all directions around the Acropolis.
Richard, Rio de Janeiro
If I had the choice of any city in the world in which to live, it would be Rio. It is one of the most romantic cities in the world, blessed with a wonderful sunny climate you can count on and a breathtaking coastline. Rio is undoubtedly one of those favoured places in the world whose names have a universal romantic appeal. The effect Rio has on the visitor is unforgettable. It is set in a stunning location surrounded by lush green vegetation and the sea.
John, Venice
Italian cities are famed for their history and culture, but to many people Venice is unquestionably one of the finest cities in the world. Constructed on an archipelago of 18 small islands separated by a dense network of waterways, Venice is geared to accommodating the millions of tourists who flock here annually. Known locally as “The Queen of the Adriatic”, Venice is best seen by water. Go sightseeing around the numerous palaces and take in the wonderful architectural heritage. Venice today still looks much as it did in the 13th century, with the exception of a few transformations to some buildings. Crowded throughout the summer months, reasonably priced accommodation is almost impossible to find, so an advance booking is essential.
