W: Good morning.
M: Good morning. Can I help you?
W: Yes, [6]is this where we register for the Beyond 2000 Conference?
M: Yes? What’s your name and I’ll get your conference bag.
W: Well, I haven’t actually registered yet. I was told I’d be able to register today, so I hope that’s OK. I’ve just arrived in Melbourne.
M: That should be fine, if you’re a student. I’ll need to take your details though. So can I have your full name?
W: Yes, sure. It’s Melanie Mitchell. I am a student at Sydney University.
M: OK. Now do you want to attend all three days? The conference runs from Thursday to Saturday.
W: Yes, I think so—if I can afford it. What does it cost?
M: Well, you’re eligible for a student discount, [7]which makes it $15 for a day registration or $40 for the three days, though it is possible to register for half a day only.
W: I’ll register for all three days, please.
M: Good. Now will you be requiring accommodation while you’re here in Melbourne?
W: Yes, I suppose I will. What’s available?
M: Well, we have several levels of accommodation. You can share a room with another student for $25 a night. Or you can have your own room but share the bathroom—that’s $45.
W: Right.
M: Or you can have a single room with your own bathroom.
W: I don’t mind sharing a room. On second thoughts, yes I do. [8]I’ll have my own room, but I’ll share the bathroom.
M: Right now a couple of other things—there are a number of special interest groups organized—they’re known as SIGs and you’re asked to nominate your preference. They’ll take place on the Friday afternoon and Saturday morning but [9]they’re filling up quickly which is why you need to nominate now.
W: Right. What are the SIGs?
M: Well, there are six altogether. Let’s see, on Friday you have a choice between Computers in Education or Teaching Reading Skills... or a session on Catering for the Gifted Child.
W: Oh they all sound interesting but technology in the classroom is really my area of interest rather than reading, so I’ll go for that. I can probably read up on the gifted child topic myself.
M: Right. And then the Saturday options are: a session on Cultural Differences; or there’s Music in the Primary Curriculum or you could go to the one on Gender Issues in the Classroom.
W: Wow! Can I go to them all? They all sound fascinating.
M: I’m afraid not.
W: Well, [10]I am really interested in how boys and girls behave differently, even when they are very young, so I’d better opt for the third session.
M: Right! Enjoy your time here with us in Melbourne.
