                                                Spare That Spider     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 least 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 an insect never more than six.         How many spiders are engaged in this work on our behalf? One authority on spiders made a census of the spiders in a grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch．Spiders are busy for at least half the year in killing insects．It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day．It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.

业余那蜘蛛为什么,你可能会觉得奇怪,蜘蛛怎么会是我们的朋友?因为它们能消灭那么多的昆虫,其中包括一些昆虫人类种族最大的敌人。
昆虫就将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,如果不是为了保护我们的禽兽。我们十分感激食虫的飞禽鸟兽,但把它们都算在一起,也只是捕杀所消灭的一小部分蜘蛛。此外,不同于其他一些食虫动物,蜘蛛从未这样做至少危害我们和我们的财物。
蜘蛛不是昆虫,而许多人认为,甚至与昆虫毫无亲缘关系可言。人能看出蜘蛛和昆虫的区别,一目了然,因为蜘蛛总是八条腿,而昆虫的腿从不超过六条腿的。
有多少蜘蛛从事着这种对我们有利的工作呢?一位权威蜘蛛做了一项统计上一块草坪上的蜘蛛在英格兰南部,他估计有2250000多人在一亩;那是大约有6000000只不同种类的蜘蛛一个足球场。蜘蛛至少有半年时间忙着年消灭害虫。它不可能会比捕杀多少昆虫只能做胡乱猜测,但是他们是饥饿的动物,不能满足于一日三餐。据估计,所消灭的昆虫的重量在英国,蜘蛛一年里的总重量比这个国家所有人加。
