#有個笑話#A linguistics professor was lecturing his class the other day. "In English," he said, "a double negative forms a positive. However, in some languages, such as Russian, a double negative remains a negative. But there isn't a single language, not one, in which a double positive can express a negative." A voice from the back of the room retorted, "Yeah, right."[微笑](from:reddit)
