【简答题】
文本 I don't normally get stage fright, but the thought of getting up in front of my colleagues to give a presentation always gives me butterflies. But I have no choice; my boss asked me to do it, so I will. I set up my projector and PowerPoint program on my laptop. Clearing my voice , I stood up and addressed the 10 people present at the meeting. I started off by saying, "Good afternoon. I want to thank you for inviting me to talk to you today." I had a clicker in my hand to advance the slides. "Today I'm going to talk to you about our new product, Provasic. Please feel free to ask questions as we go along," I said. I then flipped through the slides showing pictures of our product, and concluded by summarizing the main points of my talk with bullet points. I finished by saying, "Thank you for your attention today. My contact information is on your handout." Whew! I was glad that was over!
