一篇關(guān)于介紹蜘蛛的英語

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.

你可能會覺得奇怪，蜘蛛怎么會是我們的朋友呢?因?yàn)樗鼈兡芟麥?/p>

那么多的昆蟲，其中包括一些人類的大敵。要不是人類受一些食蟲動

物的保護(hù)，昆蟲就會使我們無法在地球上生活下去，昆蟲會吞食我們

的全部莊稼，殺死我們的成群的牛羊。我們要十分感謝那些吃昆蟲的

鳥和獸，然而把它們所殺死的昆蟲全部加在一起也只相當(dāng)于蜘蛛所消

滅的一小部分。此外，蜘蛛不同于其他食蟲動物，它們絲毫不危害我

們和我們的財(cái)物。

許多人認(rèn)為蜘蛛是昆蟲，但它們不是昆蟲，甚至與昆蟲毫無關(guān)系。

人們幾乎一眼就能看出二者的差異，因?yàn)橹┲攵际?條腿，而昆蟲的

腿從不超過6條。

有多少蜘蛛在為我們效力呢?一位研究蜘蛛的權(quán)威對英國南部一塊

草坪上的蜘蛛作了一次調(diào)查。他估計(jì)每英畝草坪里有225萬多只蜘蛛。

這就是說，在一個(gè)足球場上約有600萬只不同種類的蜘蛛。蜘蛛至少

有半年忙于吃昆蟲。它們一年中消滅了多少昆蟲，我們簡直無法猜測，

它們是吃不飽的動物，不滿意一日三餐。據(jù)估計(jì)，在英國蜘蛛一年里

所消滅昆蟲的重量超過了這個(gè)國家人口的總重量。
