描写蜘蛛的英语作文篇一:

These spiders can purr

这种蜘蛛能发出低沉的声音

Wolves howl to let others know that they're around - and maybe even that they are looking for a mate. But not the wolf spider known as Gladicosa gulosa. It makes a kind of a purr. It's quite a trick for guys of this species. And that's because it's not clear that the target of their attentions can actually hear a purr. A female may just feel the effects of that sound as vibrations in her feet. But even that may not happen unless both he and she are standing on the right surface.

狼通过嚎叫的方式告知周围它们的存在，甚至还会用这种方式求偶。但一种被称为Gladicosa gulosa的狼蛛则不然，它们会发出一种低沉的咕噜声，对于这种生物来说这样做也的确算得上是一项独门秘技。因为他们所关注的目标实际上能否听见其低鸣尚不清楚，或许雌蜘蛛只能感觉到雄蜘蛛发出声音时在它们脚底下产生的振动，可是当他们没有站在合适的平面上时雌蛛可能连振动都感觉不到。
