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

Johnny laughed.

Do you doubt^{2 that a good swimmer could3 do that? asked the teacher.}

No, sir, answered Johnny, but I wonder^{4 why he did5 not swim it four times and get back to the side6 where his clothes were.}

游泳者
老師給同學們講了一個小故事，說有一個人早飯前要在河里游泳，橫渡三趟。

約翰尼笑了。

老師問道：你不相信一個游泳非常不錯的人可以做到么？

約翰尼回答說：不是的，先生，我是不知道他為何不游四次，好回到他放衣服的那邊。

I wonder..表示我想了解
