1  Welcome to the Matrix. During the feature presentation, would you please be mindful of others and keep your voices low. We would appreciate very much if you can extinguish your cigarette and turn off your cell phone. We would also ask you not to use the alcoholic beverages and dispose all of trash in the proper receptacles when you leave. The restroom is on your right. Those who bring children should keep an eye on them, so the don’t make too much noise and wander about by themselves. If you need any further help, please go to the information office at the back. Thank you and we hope you enjoy it.
2  Thank you for your enquiry. Actually, we now have a managed floating exchange-rate system, or what many people call a dirty-float system. This means that, while there is a great degree of flexibility in exchange rates according to the balance of payment factors, the government still intervenes in the market by buying or selling large amounts of foreign currencies to provide wide-ranging fluctuations. In this way, a country’s international position could be affected by an appreciation of its currencies. For example, if a country has a high current exchange rate, its position in the world may be strong and at the same time, its economic situation might be stable. On the contrary, if its exchange rate is decreasing, its economic situation might not be so optimistic.
3  Here are your tickets. You just came in at the right time. Actually, we started a promotion campaign yesterday and this is the lowest price we have ever offered. Don’t worry about our service. As a matter of fact, we have arranged a van to pick you up at the airport and take you right to the hotel. And if you need transportation when you leave, you can contact our branch office and people there would be glad to offer you help. Tour guides are also available in the city. Here are the phone numbers of our office in case you have any further inquiry. Thank you.
4   This is David Kattering from Delta Airlines. I feel sorry to inform you that we do not have any morning flight on discount available because, you know, it is Christmas season. But we can offer you a night flight ticket with 15% off. The departure time is 11:00 and it arrives at Buffalo City at about 12 midnight. We understand it might be a bit inconvenient but this is the lowest price available at the moment. However, our airport shuffle can take you to the city for free. If you feel fine with it, you can book online right now and we’ll send you the ticket tomorrow. You may contact me at 305-6843 for any further information. Thank you.
5   Thank you for taking US Air. Here are some new services our company is providing. For the coach passengers, we are giving more of what they want: more flights to more places in the West. In addition to our new non-stop flights from Los Angeles to St. Louis and Oakland, we have added new non-stops to Denver and Phoenix from both LA and San Diego. We’ve also removed rows of seats to create more room in the coach cabin, which means we’ll offer more comfort to coach passengers than any other airline. More important, telephones have been installed at the back of the cabin, so passengers can call family or business partners at any time they like.
