If you believe the people you are trying to persude are doltish or intellectually dishonest, you are bound to betray that belief, if not directly then indirectly in your tone or choice of words. Moreover, they will generally sense your disparaging view of them and feel hurt or resentful,hardly kind of reaction that will make them open to persuasion.
如果你相信你试图说服的人是愚蠢的或智力上不诚实的，你肯定会背叛这种信念，即使不是直接，也会在你的语气或措辞上间接的背叛这种信念。此外，他们通常会感觉到你对他们的鄙视，感觉受到伤害或愤恨，这种反应很难让他们接受说服。

A caution is in order here:Don't feel you need to state your respect for your audience. Such statements have a way of sounding insincere.Work on acting respectfully. If you can accomplish that, there will be no need to state it. It will show.
这里需要注意的是：不要觉得你需要表达对听众的尊重。 这种声明听起来不真诚。 做事要恭敬。 如果你能做到这一点，就没有必要说了，它会展示。
