What makes a successful speech? First, you should have a good speech script (稿子) so that your ideas and language can attract people's attention. And some skills are necessary, too.
Here are some suggestions on giving great speeches:
◆Beat nerves
Relax yourself before and when making a speech. Practice your opening sentence three or four times. This will help make a sure start and a successful speech. When you stand on the stage, think of the audience(观众) as your family members and friends.
◆Keep it natural
Natural body languages will help your speech: smile, stand straight and look at the audience. Do not drop your head or play with a pen. Also, dressing yourself nicely will help the audience feel respected.
◆Pace and pause (节奏和停顿)
Pace and pause add color to your speech. Speak fast enough to keep people excited and slowly enough for people to fully understand you. After an important point, pause for a moment. It'll change the atmosphere (气氛)in the audience.
