听力原文：F: Good morning, Professor Zhang. Welcome to our program. Would you like to say hello to the audience? M: Hello, everyone! And good morning, Miss Zhou. I'm glad to be here to attend your program. F: It's our honor to have you here, Professor, In the past Labor's Day, we enjoyed a seven-day break. Many people spent their holidays traveling. Yet, instead of relaxing themselves, they found themselves having suffered a lot. They were trapped in hotels, railway stations, and airports because they couldn't get the tickets back they were unable to appreciate the scenery because there were huge crowds all the time. They complained to the travel agencies for their terrible services. They believed that the government is only interested in making money and care about nothing else. What's your comment on it? M: Well, the so-called 'holiday economy' should have been a good thing. To government, tourism contributes significantly to GNP, it boosts the local commerce, it provides seasonal jobs for many people thus solve or ease the problem of unemployment, and helps them to understand different customs, widen their horizons, gives them a chance to enjoy the beautiful scenery and the wonders of mankind. F: Then how come the holiday turned out to be a big headache? M: Well, the reasons are rather complicated. To put it briefly, the government had underestimated the number of the tourists. They were not fully prepared. This is indeed a lesson for us and worth thinking carefully. There is a huge potential market for developing tourism, but you have to invest a lot of things like boner facilities, better service before you make good money. Where did this dialogue take place?
