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.

从前，有个人路过江边时，发现一个成年男子抱着一个小孩，准备把他投到江里去。

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

这时候，小孩害怕了，吓得“哇哇”地乱哭乱叫。

The passer-by asked:

那个过路人就问:

"Why are you to throw the child into the river?

“你为什么要把孩子投到江里去?难道不怕他淹死吗?”

Aren't you afraid he would be drowned?"

那个男一子回答说:

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

“不要紧，他爸爸是个游泳能手。”

The passer-by then asked:

那个过路人就说:

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

“爸爸会游泳，难道他儿子不经过练习，也会游泳吗?”
