英语故事:Please speak English(请讲英语)

【英文原文】

Please speak English——请讲英语

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."
