have you ever spoken to foreighners?为什么用to?with为什么不可以

to 表示动作的对象,是to前动作主语的单方面作为.
with 虽然也是表示动作的对象,但with前后涉及的两个个体所进行的动作是互动的,是双向的.
Have you ever spoken to foreingers?
你是否曾主动跟外国人说话?
Have you even spoken with foreingers?
你是否曾和外国人交谈过?
I want to talk to you.
我有些话想和你说.（我说,你听）
I want to talk with you.
我想和你谈谈.（互动）
