Once upon a time, a man passing by a river noticed that a grown-up1 man was going to throw a child he carried in his arms into the river.

　　At this moment, the child was frightened, crying loudly and shouting in confusion2.

　　The passer-by asked: "Why are you to throw the child into the river? Aren't you afraid he would be drowned?"

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

　　The passer-by then asked: "His father can swim, but does it follow that the son can also swim without practice?"

　　從前，有個(gè)人路過(guò)江邊，發(fā)現(xiàn)一個(gè)成年男子抱著一個(gè)小孩，準(zhǔn)備把他投到江里去。

　　這時(shí)候，小孩害怕了，嚇得“哇哇”地亂哭亂叫。

　　那個(gè)過(guò)路人就問(wèn)：“你為什么要把孩子投到江里去？難道不怕他淹死嗎？”

　　那個(gè)男子回答說(shuō)：“不要緊，他爸爸是個(gè)游泳能手。”

　　那個(gè)過(guò)路人就說(shuō)：“爸爸會(huì)游泳，難道他兒子不經(jīng)過(guò)練習(xí)，也會(huì)游泳嗎？”
