毛毛虫有尾随的习惯。法国科学家法伯曾做过这样一个实验:让若干条毛毛虫在一个花盆边围成一个圆圈爬行,离花盆不远处放有毛毛虫最爱吃的松针。然而,由于这些昆虫有“相互跟随”的习性,致使他们首尾相接,一个接一个地在花盆沿上蠕动着,谁也不偏离“轨道”。七天七夜之后,这些昆虫全部饿死在花盆沿上。如果毛毛虫中有一只稍微与众不同,其他方向爬行觅食,就可以避免惨剧发生。人也是这样,绝不能一条巷子走到底,要善于另辟蹊径。以上事例对于我们的教学也有一定的启示,因而联想到我们在教学时,必须寻求 Caterpillars have trailing habits. French scientist Faber had done such an experiment: let a number of caterpillars crawl in a circle around a flowerpot, not far from the flower pot is placed caterpillars favorite pine needles. However, due to the habit of “following each other”, these insects cause them to come in contact one after another, one after the other, peristals along the flowerpot, and no one deviates from the “track”. Seven days and nights later, all these insects died of starvation in the pots. If there is a caterpillar in a slightly different, crawling in other directions for food, you can avoid tragedies. The same is true of people, must not go to an alley in the end, to be good at another way. The above examples have some enlightenment for our teaching, so think of our teaching, we must seek
