The teacher told the class the story of a man who swam a river three times before breakfast.
Johnny laughed.
"Do you doubt 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."
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，横渡三趟。
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四次，好回到他放衣服的那边。”

I wonder…..表示我想知道…
