《伊索寓言》里有一个故事:长颈鹿和山羊一起觅食。在一堵高墙围住的草地外,有几棵高大的树枝伸了出来。长颈鹿一伸颈就吃到了树叶,山羊则只能吞唾液。后来,山羊发现围墙下有个洞,于是钻进围墙,吃草地上的嫩草,而长颈鹿却垂头丧气,因为它钻不过墙洞。 There is a story in Aesop’s Fable: Giraffes and goats feed together. Outside a wall surrounded by tall walls, several tall branches stretched out. The giraffe eats the leaves as soon as it reaches the neck. The goats can only swallow saliva. Later, when the goat found a hole under the wall, he drilled into the wall and ate the tender grass on the grass. The giraffe was dejected because it bored no holes in the wall.
