    Hello, ladies and gentlemen. It gives me great honor to introduce our speaker for today’s lecture, Dr. David Robinson. Dr. Robinson, professor of human resource at Northwestern University,(16)has written numerous articles and books on the issues about how to give a good presentation in front of many people: it is not enough to just express your own opinions, but also make your audience absorbed and involved.
Dr. Robinson:
    Thank you for that introduction. I feel honored to give a speech here. It’s common: You are in the middle of your presentation when you realize that your audience is not listening to you. You can’t hold their attention. Someone is not listening: someone else is talking with his friend, and there are even few people who are sleeping. At the end of your presentation, you feel pretty bad about your performance. You can’t understand: You offered many interesting ideas, but they were bored. You trained for that presentation every day in the past few weeks. You are pretty sure that your speech was great. How is it possible that people weren’t listening to you? You feel confused and a little frustrated. Probably you don’t know one thing...
    The problem wasn’t you: the problem was your presentation. Most of the presenters don’t make good slides. Be honest: How many boring, flat, black and white presentations have you seen on the screen over the last years?(17)If you take a look at SlideShare, you’ll notice that most of the presentations there are boring. Not one, not two, not half. .. most of the presentations! The fault isn’t of the presenters: No one taught them how to make a great presentation: no one taught them that their slides are as important as their speech.
    The only way to make people listen to you is to grab their attention with a phenomenal presentation. If your slides show a lot of text, they will bore people. People are lazy: they don’t want to read while you are speaking. They don’t need to read what you are saying them. If your slides are black and white, they’ll appear uninteresting. If your slides show confused data and/or text, people won’t pay attention.(18)People want to learn while they get entertained. Some boring slides won’t entertain them.
    Making a great presentation is pretty easy if you know how to do it.
     (19)Images can be very powerful. They are probably the most important part of the presentation. Through the right images, you can evoke emotions in your audience. Think about how effective funny images are. Another example is shocking images: they have a great impact(but don’t exaggerate!). One thing that you should avoid with images is to insert clip art. They are horrible. When you see a clip art on a presentation, you instantly perceive it as unprofessional.
    Use your images to cover the whole slide. Smaller images can work well if you use them well, but avoid them if you don’t know how to put them in an excellent way.
    Use similar images. If your images seem to come from a related source, your presentation will get a more professional and better look.
    Thank you all! Hope today’s lecture will help you!
