一位哲学家带着他的弟子在郊外的草地上坐了下来。哲学家说:“你们看,我们周围长满了野草,现在我想知道的是如何铲除它们!”一个弟子首先开口:“老师,只要有一把铲刀就够了。”哲学家点点头。“用火烧也是很好的办法。”“撒上石灰,可以铲掉所有的野草。” A philosopher sat down with his disciples on the grass outside. The philosopher said: “You see, we are surrounded by weeds, and now I want to know how to eradicate them!” A disciple first spoke: “Teacher, as long as there is a blade enough.” Philosophers Nod. “Use fire is also a good way. ” “Sprinkle with lime, you can shovel out all the weeds. ”
