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 didn't swim it four times and get back to the side where his clothes were."
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：“你不相信一个善于游泳的人可以做到吗？”
约翰尼回答道：“我相信，先生，但是我纳闷他为什么不又四次，这样他才可以回到放衣服的那边。”
