I'm a high school geometry teacher and I started one lesson on triangles by reading a theorem. “If an angle is an exterior angle of a triangle, then its measure is greater than the measure of either of its corresponding remote interior angles.” I noticed that one student wasn't taking notes and asked him why. “Well,” he replied sincerely, “I'm waiting until you start speaking English.”
我是高中的幾何老師。在上一堂關(guān)于三角形的課的時候,我開始念一個定理:“三角形的外角大于任何一個不相鄰的內(nèi)角?!蔽易⒁獾揭粋€學(xué)生沒有做筆記,就問他為什么。他真誠地說:“嗯,我在等你開始講英語。”
