赋予演讲生命力——vitality,aliveness, enthusiasm

People cluster around the energetic speaker like wild turkeys around a field of autumn wheat.
活力四射的演讲者就是听众的“香饽饽”

Put enthusiasm and excitement into your speaking
First

Choose subjects you are earnest about

Unless you are emotionally involved in the subject matter you have chosen to talk about, you cannot expect to make your audience believe in your message.
进入演讲情绪，听众才更买账

Second

Relive the feeling you have about your topic

So, the more you relive the scene you are describing, or recreate the emotions you felt originally, the more vividly you will express yourself.
这里我理解为“情景再现——Yesterday once more”
We have become so fearful of giving vent to our feelings in public that we have to go to a play to satisfy this need for emotional expression.
-give vent to our feelings 发泄情感
人们羞于公众场合宣泄情感，但内心又想满足这种述求，观看话剧和舞台剧就是不错的选择。
所以演讲者也应当抓住听众需求，吸粉一波

Third

Act in earnest

When you walk before your audience to speak, do so with an air of anticipation, not like a man who is ascending the gallows.
上讲台应当趾高气扬，而要像上刑场一样。

不知道有没有“心理回应”这一说法，但下面两句话，后续要找下原因和资料

Once you begin making geatures of any kind, they will help to stimulate you.
Act in earnest and you will become naturelly earnest in all you do.
《思考，快与慢》中，提到“启动效应”，动作会不知不觉地影响到我们的想法和感觉；
或是“自我强化”作用。
