Hello, class, today we're going to be learning about a lot of things about public speaking. I'll be your instructor---okay, how dreadful was that? All right, that's what I'm talking about. We need to talk about inflection ( 声调变化) , or 1) __________, or variables, or whatever you want to call it. Me personally, I call it being delicious. I want you to be delicious with your voice. So, you can't talk in a 2) ______________when you deliver your speech. You've got to use the highs and lows of your voice. We've got our 3) __________ set, we've got our volume set, now sometimes, something is going to be more important. Maybe you give it a little more 4)__________. Maybe at some point in your speech you get really 5) ___________, and you're going to use a higher pitch. Maybe at some point in your speech there is something very serious that you want to talk about, so you use the 6) __________ register ( 音域;声区 ) of your voice. But what we're looking for is a variety of 7) ________________, ups, downs, fast, slows, and maybe even loud-softs. That's inflection. It doesn't matter what you do, as long as you don't give every single word the same 8) ___________. And what I mean by that is if I say a line, “I like pizza”, and then I say the line, “the building's on fire”, and I give them both the same value, then that means nothing. I like pizza, I love pizza. The building is on fire. Okay, those are two totally different things. And I need to inflect them 9) __________ so that you the listener, you the audience, know how 10) _______________. Inflection--it's really cool stuff.
