小學(xué)英語作文：Spare that spider不要傷害蜘蛛

　　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.

　　你可能會覺得奇怪， 蜘蛛怎么會是我們的朋友呢?因為它們能消滅那么多的昆蟲，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物。
