Presentation on Nanotechnology
ANNOUNCER: Section 3. You will hear a student called Russ consulting his tutor about a presentation he is preparing on nanotechnology, the study of materials on an extremely small scale. First, you have some time to look at questions 21 to 25. Now listen carefully and answer questions 21 to 25.
TUTOR: Ah... come in, Russ.
RUSS: Thank you.
TUTOR: Now you wanted to consult me about your class presentation on nanotechnology. You're due to give it next week, aren't you?
RUSS: That's right, and I'm really struggling. I chose the topic because I didn't know much about it and wanted to learn more. But now I've read so much that there's almost too much to say. I could talk for much longer than the 20 minutes I've been allocated.
RUSS: Should I assume the other students don't know much and give them a general introduction, or should I focus on one particular aspect? 21
TUTOR: You could do either, but you'll need to have it clear in your own mind.
RUSS: Then I think I'll give an overview.
TUTOR: One way is to explain the developments in chronological order. Another way is to discuss the different applications of nanotechnology.
RUSS: You mean things like water-repellent films on camera displays or materials that make motorcycle helmets stronger and lighter?
TUTOR: Exactly. Or you could focus on its impact in one area, such as medicine or space exploratio
. 22
RUSS: That might make it easier to focus. Perhaps I should do that.
TUTOR: Yes, that would be a good idea.
RUSS: How important is it to include slides in the presentation?
TUTOR: They aren't essential. Sometimes people spend too long looking for suitable slides, so it might actually be better to leave them out. 23
RUSS: I was also wondering how to start the presentation.
TUTOR: Asking the audience questions might take too much time.
RUSS: Maybe I should begin with an example of how nanotechnology is used.
TUTOR: That sounds sensible. 24
RUSS: What should I do next while preparing?
TUTOR: Ignore all your notes at first. Write one short sentence that summarizes the whole presentation, something like: Nanotechnology is already improving our lives. Then plan the rest around that idea. 25
ANNOUNCER: Before you hear the rest of the discussion, you have some time to look at questions 26 to 30. Now listen and answer questions 26 to 30.
TUTOR: Now let's think about actually giving the presentation. You've only given one presentation before.
RUSS: Yes, and it wasn't very good.
TUTOR: The structure needed improvement. You finished too suddenly without a proper conclusion. 26
TUTOR: You also made very little eye contact because you were looking at your notes most of the time. 27
TUTOR: Your body language was distracting too. You kept turning around to look at the slide and even scratched your head repeatedly. 28
RUSS: Oh dear. What about my language?
TUTOR: Actually that was good. You used technical terms but always explained them clearly. 29
TUTOR: Your handouts were also excellent because they summarized the presentation well and were useful for the audience afterwards. 30
RUSS: Thank you.
TUTOR: I hope that helps you improve next week's presentation.
RUSS: Yes, it definitely will.
ANNOUNCER: That is the end of section 3. You now have half a minute to check your answers.
