英国著名的解剖学家麦克劳德,在回忆自己上小学时的“调皮捣蛋”时,讲了一件有意义的往事。他说:这么多年过去了,那件事一直萦绕在脑海,不能忘记,更不能忘记那位可敬的小学校长。那时他是个令人感到非常头痛的“坏孩子”,是他所在的区里有名的淘气鬼。小麦克劳德经常想出一些大胆的坏主意。一天,他正和伙伴们玩耍,忽然,发现校长那只心爱的小狗正摇着毛茸茸的尾巴跑过来。麦克劳德产生了一个可怕的想法——杀了这只狗,看一看动物的内脏是个什么样子,就和几个小朋友一起把校长心爱的狗杀了。校长得知后非常生气,但处理方法却令人耳目一新:罚学生画一副动物的骨骼图和一副血液循环图。学生知道自己闯了大祸,便认真地画了两张图交给校长。校长见学生认错态度较好,图形画的认真仔细,便免去了这几个学生的处分,杀狗的事就这样过去了。学生在画图的过程中通过对狗的骨骼、内脏的仔细观察,对科学产生了极大的兴趣,同时深深地体会到自己知识的缺乏,从此发奋学习。那位带头杀狗的“坏学生”就是后来成为获得诺贝尔奖的解剖学家麦克劳 McLeod, a well-known English anatomist, recalled a meaningful past when recalling his “Naughty” when he was in elementary school. He said: After so many years have passed, that thing has been lingering in our minds. We must not forget that we should not forget the respectable primary school principal. At that time he was a “bad boy” who had a very bad headache. He was a famous naughty boy in his district. Little MacLeod often came up with some bold bad ideas. One day, he was playing with his companions. Suddenly, he found out that the headmaster’s beloved puppy was shaking his furry tail. McLeod produced a terrible idea - kill the dog, look at what the animal’s internal organs look like, and kill the headmaster’s beloved dog together with several children. The principal was very angry after learning of this, but the treatment method was refreshing: Students were given a skeletal map and a blood circulation chart. When the students knew that they were in great trouble, they took the two maps seriously and gave them to the principal. The principal observed the student’s attitude of confession was good, careful and careful graphics, it will remove the punishment of these students, killing the dog so passed. In the process of drawing pictures, students have aroused great interest in science through careful observation of the bones and internal organs of dogs. At the same time, they deeply understand the lack of their own knowledge, and learn from them. The “bad student” who took the lead in killing the dog was later to become the Nobel Prize anatomist McCraw.
