The Swimmer
The teacher told the class the story of a man who swam a river three times before breakfast.
Johnny laughed. “Do you doubtdoubt v.怀疑， 不信， 拿不准， <古>恐怕 that a good swimmer could do that？” asked the teacher.
“No， sir，” answered Johnny， “but I wonder why he did not swim it four times and get back to the side where his clothes were.”
所谓智慧是指由最好的方法谋取最好的结果。
游泳者
老师给同学们讲了一个小故事，说有一个人早饭前要在河里游泳，横渡3趟。约翰尼笑了。老师问道：“你不相信一个游泳很好的人可以做到么？”约翰尼回答说：“不是的，先生，我是不明白他为什么不游4次，好回到他放衣服的那边。”
