Cheer up!It doesn’t have to be that bad. Here are some simple steps to take the pain out of speech making. Ask yourself the reason for your speech. What is the reason? Why are you speaking? Then collect as many facts as you can on your subject. Spend a great deal of time organizing your speech so that it is clear and easy to follow. Use as many examples as possible, and use pictures, charts (图表) if they help make your points clearer. Never forget your audience. Treat your audience with respect(尊重) .They will like listening to you more.
