Lesson 2-1 Spare that spider
不要伤害蜘蛛
Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings.
Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and insect never more than six.

你可能会觉得奇怪, 蜘蛛怎么会是我们的朋友呢?因为它们能消灭那么多的昆虫,其中包括一些人类的大敌,要不是人类受一些食虫动物的保护,昆虫就会使我们无法在地球上生活下去,昆虫会吞食我们的全部庄稼,杀死我们的成群的牛羊。我们要十分感谢那些吃昆虫的鸟和兽,然而把它们所杀死的昆虫全部加在一起也只相当于蜘蛛所消灭的一小部分。此外,蜘蛛不同于其他食虫动物,它们丝毫不危害我们和我们的财物。
许多人认为蜘蛛是昆虫,但它们不是昆虫,甚至与昆虫毫无关系。人们几乎一眼就能看出二者的差异,因为蜘蛛都是8条腿,而昆虫的腿从不超过6条。
