     Venice is the "Queen" of the Adriatic Sea (亚得里亚海). Every year thousands of people from all over

the world travel to Italy to visit the city. Do you know why they like to go there for a visit?

     Venice is a very beautiful city. It is quite different from other cities in the world. There aren't any roads

and streets in the city. So there aren't any cars and buses. There are many canals (运河) in the city. There

is one big canal and one hundred and seventy-seven small canals. People move up and down the canals in

boats to go to work, go shopping or visit their friends.

The Adriatic Sea will cover the city. The Venetians (威尼斯人) love their city and want to stay there. So

they want to save Venice from the sea. They do not want to leave. How can they save Venice? They can

build some strong huge walls and gates in the sea. The gates will close to keep too much water out. Thus

Venice will not sink.
