【答案解析】[解析] 22-25
W: We learn that a lot of our listeners are studying online. So they'll be interested to hear what our guest has to say. (22) {{U}}Mark McRae, is a lecturer at Manchester University whose specialist area is online moderation.{{/U}} Mark, what makes moderators different from teachers in a classroom?
M: Hi June. I think the first point is that, online or not, (23) {{U}}the most important thing is well-designed learning goals{{/U}} -- the use of technology is secondary to getting the learning goals right. But there are obviously differences between online and face to face learning. Just as an example, people often like classroom teachers who make them laugh, but trying to be funny in computer conferencing is a dangerous business and often not very successful.
W: Why is that?
M: Mainly because, (24) {{U}}when you're just reading text--you can't hear the person's tone of voice or see their face--it's much easier to misunderstand.{{/U}}
W: What if people argue? Does that happen?
M: It does. As I said, it's much easier to have misunderstandings when communication is all text-based and people will, occasionally, flame each other.
W: Flame?
M: Sorry. Flaming is what happens when one person "attacks" another person online. It doesn't happen very often.
W: And how do you deal with it?
M: Well, it's up to the moderator to set the rules for how people interact, and (25) {{U}}if someone breaks those rules the moderator will talk to him or her privately{{/U}} and remind them of how we should deal with each other. It's the same with students who aren't participating actively--the moderator may decide to talk to them privately and check they're OK.
