     Geneva is situated between the Jura Range and the Alps on the western end of Lake Geneva. Capital

of Peace is one of its names- the European headquarters of the United Nations lies here in Palais des

Nations. Another worthy name for this city with a humanitarian tradition (人道主义传统) and international

character is the World's Smallest Metropolis. Parks, splendid stores and lively streets in the old part of town

and its 2000-year history wait to be discovered.

     The Jet d'Eau together with the Flower Watch are the main attractions every year for the tourists visiting

Geneva. The Jet d'Eau has become the symbol (象征) of Geneva for a long time. This is a 140 meters high

water monument with a rich history. Eight 13,500-watt projectors light the grand column (圆柱) of the

fountain in the evening, from early March until the second Sunday of October. The Flower Watch, which

was created at the edge of the English Garden in 1955, reminds us about that Geneva is the birthplace of

the Swiss clock and watch making, and that this industry has become internationally famous, as well through

the quality of the watches as through their beautiful appearance.

     Sails on Lake Geneva are also enjoyable. The Lake of Geneva, lying among the Alps, is a true inland sea,

making possible a wide range of pleasant boat trips, you can relax and watch the beautiful scenes pass by.
