The teacher told the class the story of a man who swam a river three times before breakfast.

　　Johnny laughed.

　　"Do you doubt² that a good swimmer could³ do that?" asked the teacher.

　　"No, sir," answered Johnny, "but I wonder⁴ why he did⁵ not swim it four times and get back to the side⁶ 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…
