听力原文：W: So, what special needs do business travelers have？
M: [10] One of the most important things is a quick check-in and check-out. Room service is also very important. [7]Guests often stay in their rooms working and don't have the time to go out to a restaurant, so they want their meals served in their rooms.
W: And what facilities are there in the rooms？
M: Well, nowadays communication facilities are essential, so things like a modem socket and a fax are very important.
W: Yes, of course.
M: The lighting is also very important. [10]As I said, guests often spend their evenings preparing work, so they need good lighting at their desks.
W: And what about facilities in the hotel in general？
M: The bars are important. [8]Corporate guests tend to spend much more time in the hotel bars than tourists. It's very important to provide a business centre, too.
W: What services does the business centre provide？
M: Basic secretarial services such as photocopying and typing. [9]It also coordinates conferences and any catering which is included in them.
W: Right, [10] and what about distance to the airport and city centre？ Is that important？
M: Yes. We're in the east of London so we're near City Airport. A lot of our guests have meetings in this area, so they don't want to be near Heathrow Airport or right in the city centre.
