37、. So, to begin with, lets review a few of the points weve discussed so far. Remember that, for centuries, the city has been struggling with the problem of flooding. As you know, the regular floodwaterscalled the acqua altaare a big problem in the city. You may also recall that the government has sta
38、rted the innovative MOSE project to build water barriers and stop flooding from the ocean.,To be continued ,Listening 1,Now, flooding is an important issue, but many Venetians say that the city has more serious problems than the acqua alta or the MOSE project. And most of these problems have to do w
39、ith tourism. Of course, tourism has both the positive and negative sidetourism is extremely profitable. But the problem in Venice is too many tourists. For example, in 2007 the number of Venetian residents was 60,000. And what do you think the number of visitors to Venice was in that year? Twenty-on
40、e million! Recently, on a single holiday weekend in May, 80,000 tourists visited the city. Public parking lots filled up and were closed. And tourists walked through the streets eating and drinking and leaving a lot of trash behind.,To be continued ,Listening 1,The result is that Venices city servic
41、es just cant handle so many people. The city has to pay more and more money for garbage collection to clean up all of the trash. In addition, public transportation on the famous boats and gondolas is so crowded that Venetian residents can barely find room to get on. Along with trash and crowded tran
42、sportation, city residents also have to deal with higher prices for food and for housing. Food prices continue to rise around the city. Some cafs charge as much as 13 U.S. dollars for a soft drink! In the Rialto Marketan area with many shops and storessome of the grocery stores have been,To be conti
43、nued ,Listening 1,replaced by souvenir shops, which means that Venetians have fewer places to buy their groceries. In popular tourist areas, rent has almost tripled, and many small local businessesfor example, toy stores and hardware storescant afford to pay. Let me add that there is a serious housi
44、ng problem in Venice. At one time, there were regulations making it illegal to convert residential buildings into hotels. But a law in 1999 removed those regulations, and the housing problem got even worse. Since then, the number of hotels and guesthouses has increased by 600 percent, and the number
45、 of houses that are available for local residents has gone down.,To be continued ,Listening 1,These days, housing is only affordable for the very rich or for people who already own houses because theyve been passed down by family. Young Venetians simply cant afford to buy any property in the city. T
46、his has forced a huge number of Venetian residents to move out of the city. Thirty years ago, the population of Venice was around 120,000. Now its less than 60,000. So, why does Venice continue to encourage tourism when it causes so many problems? Mainly its because tourism in Venice generates more
47、than two billion U.S. dollars a year in revenueand many think that the amount is much higher.,Listening 1,To be continued ,Also, theres a lot of financial pressure on Venice. The cleaning of canals, restoration of old structures, and the MOSE project are all very expensive. Tourism brings in money t
48、o help the city solve these problems. Another point I want to make is that many people in Venice have jobs related to tourism. As more tourists come to the city, hotels, restaurants, and museums need to hire more workers. In fact, the city of Venice has a lower unemployment rate than the rest of Ita
49、ly, and its likely a result of the tourism industry.,Listening 1,To be continued ,Some people think that Venice is to blame for its own problemsthat these problems are the result of greed for tourists money. Theres a lot of talk about limiting tourists, taxing tourists, and even asking tourists to avoid the busy seasons of Easter and Carnival. However, as you can see, maximizing the number of tourists in Venice is also necessary. So, there seem to be no simple solutions to Venices tourism problem.,Listening 1,Listening 2,conform v. 遵守，遵从 built-up a. ( 区域) 布满建筑物的 compatible a. 能共存
