Once upon a time, a man passing by a river noticed that a grown-up man was going to throw a child he carried in his arms into the river.

　　從前，有個人路過江邊時，發(fā)現(xiàn)一個成年男子抱著一個小孩，準備把他投到江里去。

　　At this moment, the child was frightened, crying loudly and shouting in confusion.

　　這時候，小孩害怕了，嚇得“哇哇”地亂哭亂叫。

　　The passer-by asked:

　　那個過路人就問:

　　"Why are you to throw the child into the river? Aren't you afraid he would be drowned?"

　　“你為什么要把孩子投到江里去?難道不怕他淹死嗎?”那個男一子回答說:

　　The man answered:"It doesn't matter. His father is good at swimming."

　　“不要緊，他爸爸是個游泳能手。”

　　The passer-by then asked:

　　那個過路人就說:

　　"His father can swim, but does it follow that the son can also swim without practice?"

　　“爸爸會游泳，難道他兒子不經(jīng)過練習，也會游泳嗎?”
