在希望获得听众互动的较长的讲演中，要点可能会有好几个，但越少越好，而且都必须有支持的材料。在第三章里，我们讨论过一种支持讲演重点的方法，凭借故事，或出于自己生活的经验来说明，使听众去做讲演者要他们去做的事情。这种类型的例子很受欢迎，因为它诉诸人类心中的一种基本倾向，就是“人人爱故事”。事件或意外是一般演讲者最常使用的例子，但不是可以支持要点的唯一方法。你还可以使用统计数字，依科学方式归纳的图解、专家的证言、类比、展示或证明等。In the longer talk to get action yon will have several points; the fewer the better, but all of them will require support material. In Chapter Seven we discussed one method of supporting the Point of a talk, which is what you want the audience to do, by illustrating it with a story, an experience out of your life. This type of example is popular because it appeals to a basic drive in people, summed up by the slogan, "Everybody Loves a Story." An incident or happening is the kind of example most often used by the average speaker, but it is by no means the only way your point can be supported. You might also use statistics, which are nothing more than illustrations scientifically grouped, expert testimony, analogies, exhibits, or demonstrations.
