Venice(威尼斯) 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 or streets in the city, so there aren't any cars or 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.

But Venice is sinking(下沉)It is going down and the water is going up. In 2040 Venice will be under water. The Adriatic Sea will cover (覆盖) the city. The Venetians(威尼斯人) love their city and want to stay there. So they want to save(拯救)Venice form the sea. They do not want to leave. How can they save Venice?
