一篇关于介绍蜘蛛的英语

Why, you may wonder, should spiders be our friends?

Becau they destroy so many incts, and incts include some

of the greatest enemies of the human s 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 inct-eating owe a lot to the

birds and beasts who eat incts but all of them put together kill

only a fraction of the number destroyed by er,

unlike some of the other inct eaters, spiders never do the least

harm to us or our belongings.

Spiders are not incts, as many people think, nor even

nearly related to can tell the difference almost at a

glance, for a spider always has eight legs and an inct 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 s are busy for

at least half the year in killing 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 has

been estimated that the weight of all the incts destroyed by

spiders in Britain in one year would be greater than the total

weight of all the human beings in the country.

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。

有多少蜘蛛在为我们效力呢?一位研究蜘蛛的权威对英国南部一块

草坪上的蜘蛛作了一次调查。他估计每英亩草坪里有225万多只蜘蛛。

这就是说，在一个足球场上约有600万只不同种类的蜘蛛。蜘蛛至少

有半年忙于吃昆虫。它们一年中消灭了多少昆虫，我们简直无法猜测，

它们是吃不饱的动物，不满意一日三餐。据估计，在英国蜘蛛一年里

所消灭昆虫的重量超过了这个国家人口的总重量。
