715　Double Positive 双重肯定

A linguistics professor was lecturing his class. “In English,” he explained, “a double negative forms a positive. In some languages, such as Russian, a double negative is still a negative. However, there is no language in which a double positive can form a negative.” A voice from the back of the room piped up, “Yeah, right.”

一位语言学教授正在给学生讲课。他解释说：“在英语里，双重否定构成肯定。在别的语言中，比如俄语，双重否定还是否定。然而，没有一种语言可以用双重肯定构成否定。”这时候，从教室的后面蹦出一个声音：“是啊，对！”
