一、案例法国的自然科学家法伯曾做过一次有趣的“毛虫实验”。法伯把一群毛虫放在一个盘子的边缘,让它们一个跟着一个,头尾相连,沿着盘子排成一圈。于是毛虫们开始沿着盘子爬行,每一只都紧跟着自己前边的那一只,既害怕掉队,也不敢独自走新路。它们连续爬了七天七夜,终于因饥饿而死去。而在那个盘子中央,就摆着毛虫们最喜欢吃的食物。

First, the case of France's natural scientist Faber had done an interesting “caterpillar experiment.” Farber placed a group of caterpillars on the edge of a plate, one after the other, head-to-tail, and lined up along the plate. So the caterpillars began to crawl along the plate, each followed by the one in front of him, both afraid of leaving behind and not daring to walk alone. They climbed continuously for seven days and nights and finally died of starvation. In the center of the plate, the caterpillars are most like to eat food.
