描写蜘蛛的英语作文篇一：

These spiders can purr

(资料图)

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。

描写蜘蛛的英语作文篇二：

How the spider purrs

蜘蛛如何发出低鸣声?

At mating time, male wolf spiders try to catch a female"s attention by creating "persuasive" vibrations, Sweger says. They strum one structure on their body against another - somewhat as a cricket does - to impress the gals. Getting the message right can be a matter of life and death to the guy who"s doing the wooing. If the female isn"t totally convinced that he"s the "one," it could be worse than just being rejected, Sweger explains. "She could eat him." About one out of every five male wolf spiders will be eaten by the female he had been wooing. But the guys who prove suitably persuasive will get to mate - and live to tell the tale.

求偶时雄性狼蛛会使出浑身解数用"劝诱"的振动方式吸引雌性狼蛛的注意，他们用身体的一部分拍打另一部分发出震动声(就像蟋蟀一样)，而后给雌蜘蛛留下印象。Sweger表示能否正确收到求爱信息关系着求爱者的性命，如果雌蜘蛛没能被完全说服他就其 "真命天子"，那么雄蜘蛛的情况有可能比被拒绝还要糟糕，他可能会被她吃掉。这并不稀奇，因为每五个雌性狼蛛中就有一个被他们的所追求的另一半吃掉。但如果事实证明雄蜘蛛的确有劝诱能力，那么他们最终将会得到交配的机会，并向配偶讲述他们悲惨的"浪漫际遇"。

Purring spiders "are using the same vibratory tactics as every other wolf spider in North America. More or less," Sweger says. "They"re using the same structures. And they"re making vibrations."But the scientists showed that compared to the wooing vibrations made by other wolf spiders, those by Gladicosa gulosa are far stronger.

Swege称在北美这种能发出低吟声的蜘蛛或多或少使用的都是和所有其他狼蛛一样的振动技巧。它们使用的是同样的身体结构来产生振动。但科学家表示，与其他发出求爱振动信号的狼蛛相比，这种名为Gladicosa gulosa的狼蛛的振动更加强烈。

Sweger discovered something else as well. When a purring spider was on a surface that is good at conducting vibrations, such as leaves, an audible sound was produced.

Sweger还发现了其他一些东西。当一只低吟的狼蛛处在更有利于传导振动的位置，比如说树叶上时它们会发声音。

If a person is within a meter of the courting spiders, they can actually hear the sound. "It"s very soft, but when we"re out in the field, you can hear them," Sweger says. The sound, he explains, is a bit like a "little strumming chirp" or a "soft rattle or purr." (You can judge for yourself.)

Sweger表示当一个人距离一只正求偶的狼蛛仅一米时，他会听到这种声音，和柔和。但当我们在野外时，你也会听到它的声音. 这种声音类似于有节奏的唧唧声，或者是那种柔和的咯咯声、咕噜咕噜的声音等等(这就得靠你自己判断了)。

描写蜘蛛的英语作文篇三：

Spare that spider不要伤害蜘蛛

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 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.

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。

蜘蛛侠英语作文：

Tonight I watched the movie for the third time. I really enjoy this film so much.

So what"s your choice between being a common person or a hero with people"s respects? Most people will choose the latter. But what will be your choice if the cost is laying your lover among the risks? What will it be if the cost is you can never tell the girl who you love so much that you love her? The spider man had this contradiction. But finally he still chose the latter not in order to be a hero but to make this word peaceful.

I was so moved by the words the Aunt Mary said:

You will never guess what he wants to be the spider man. He knows the hero when he sees one too a few characters out there flying all around out there saving old girls like me. Lord knows kids like Henry need hero courageous sacrificing for people setting examples for all of us. Everybody loves a hero. People enthrone them cheer them scream their names and years later they will tell how they stood in the rain for hours just to get a glimpse the one who taught them to hold on to stand longer. I believe there is a hero in all of us. They keep us be honest give us strength make us noble and finally allow us to die with proud. Ever though sometimes we have to initiatively give up the thing we want most even our dreams. Spider man did that for Henry so he wants to know where he is gone. He needs him.

The spider man got much from these words so did I. And what about you? what"s the hero lying in you?
