曾经看到过这样一个故事:闻一多先生有一次给学生上课,他走上讲台在黑板上写了.一道算术题:2+5=?学生们疑惑不解,等于7嘛。闻先生说,不错,在数学领域里,2+5=7,这是天经地义的,但在艺术领域里却可以有更多的想像。他拿出了一幅题为《万马驰骋》的国画让学生欣赏,只见画面上突出地画了两匹奔马,后面又错落有致、大小不一地画了五匹马,这五匹马的后面便是许多影影绰绰 I have seen such a story: Mr. Wen Yiduo once taught the students, and he took the podium to write on the blackboard. An arithmetic problem: 2+5 =? Students are puzzled and equal to seven. Mr. Wen said that it is true that in the field of mathematics, 2+5=7, which is genius, but in the field of art there can be more imagination. He took out a Chinese painting titled “Hundred Horses and Galloping Horses” for students to appreciate. He saw two horses drawn prominently on the screen. Five horses were painted in five different sizes. Behind the horse is a lot of shadows.
