阅读下面的短文，并完成短文后的任务。

      You will find traffic noise disappearing as soon as you arrive in Venice. So as you walk down the narrow

streets, you only have to avoid (避免) crowds of people. (3) About 19 million travellers visit Venice for the

enjoyable environment, art and food each year.

      Seeing Venice on foot is the best. You can walk through the city in about an hour. Look around St.Mark's

Basilica and the Doge's Palace. (4) But you should know walking along the streets isn't as easy as traveling on

the city's canals. The canals are Venice's "streets". And you can enjoy the Grand Canal, the Rialto Bridge and

many wooden buildings.

      Venice is fantastic. You shouldn't miss it in your life. No matter how long you're in Venice, it will leave a

pleasant feeling on you.

1. Why will you find noise disappearing as soon as you arrive in Venice?

2. What can you enjoy in Venice when traveling on the city's canals?
