B: May I speak to Thomas Nelson?
A: This is Thomas speaking. May I ask who’s calling?
B: This is Lee Ting, the secretary at the Dean’ Office.
A: Hi, Miss Lee, what’s up?
B: I’m calling to inform you about some changes in our arrangement for your seminar next week.
A: Yes, what are the changes?
B: The first change is that the seminar will be moved to the law school Auditorium. The time will be 3:00 pm on Monday.
A: Ok, seminar, 3:00 pm Monday. What else?
B: I want to know if you have any special needs for facilities for your presentation?
A: Well, I need a PowerPoint projector or an overhead projector.
B: OK, overhead projector, or PowerPoint projector. What about the audio equipment? Do you want me to arrange a wireless microphone for you?
A: Well, I think a microphone on the podium will do. I don’t move too far from the podium when I make a presentation.
B: Sure, we’ll put a microphone on the podium. Oh! And finally, the field visit has been cancelled owing to your time constraints.
A: That’s too bad. I was really looking forward to visiting the experiment facility.
B: In that case, should I tell the Dean that you had really hoped to see the lab?
A: It’d be very kind of you if you would let him know.
B: Sure, I’ll let him know as soon as he returns to the office.
