动物说明文400字作文 篇1

大黑蜘蛛

Big black spider

一只身长约4厘米的大黑蜘蛛

Big black spider在我家的屋顶上结了一个大网。

这只大蜘蛛的腿又细又长，肚子大大的，圆圆的。看上去很笨，可是在网上行走时又快又轻巧，看起来比杂技团走钢丝的演员还要自如。

The legs of this big spider are thin and long, and its belly is big and round. It looks stupid, but it is fast and light when walking on the Internet. It looks more comfortable than the acrobat walking on the tightrope.

蜘蛛可是捕捉猎物的高手。一次，有一只蚊子飞着飞着，不小心掉到了蜘蛛织的大网上，蜘蛛飞快地向蚊子扑去，把蚊子吞进了肚子里。不一会，一只鲁莽的飞蛾闯到了网上，它拼命地挣扎着，蜘蛛马上从尾部抽出丝来，去缠飞蛾，它缠呀缠呀，一直缠到飞蛾不再动弹为止。

Spiders are masters at catching prey. Once, a mosquito was flying and accidentally fell onto the spider web. The spider rushed at the mosquito and swallowed it. After a while, a reckless moth ran into the web, and it struggled desperately. The spider immediately drew silk from its tail and wound the moth. It wound and wound until the moth stopped moving.

蜘蛛不仅是捕猎高手，还是预报天气的高手。有一次，我看见蜘蛛在网的中间，一直不动，过了一会儿，天下起了大雨，连续下了好几个小时。雨小了一点，蜘蛛又重新忙碌地织新的网。不一会儿，雨便停了。我很疑惑：为什么蜘蛛在网中间就会下雨，重新织新的网雨就会停了呢？我去查看了资料，终于知道了原因，蜘蛛的行动和天气有着密切的关系，如果蜘蛛在网中间，那么就证明天要下雨了，如果蜘蛛重新织网，天就要放晴了。

Spiders are not only good hunters, but also good weather forecasters. Once, I saw a spider in the middle of the web, and it was still. After a while, it began to rain heavily for several hours. The rain was a little light, and the spider was busy again weaving a new web. After a while, the rain stopped. I am very confused: Why does it rain when spiders are in the middle of the web, and the rain stops when they weave new webs? I went to check the information and finally found out the reason. The spider's action is closely related to the weather. If the spider is in the middle of the web, it will rain tomorrow. If the spider weaves the web again, it will clear up.

啊！我太喜欢蜘蛛了，特别是它有能预报天气的能力。

Ah! I like spiders very much, especially their ability to forecast the weather.

鲫鱼是一种水性动物，也是体外受精的鱼类中的一种，春、秋季节是鲫鱼产卵的好季节，每到这时它们的精子和卵子就会在水中受精形成受精卵，大约10—20天左右就会开始发育，2月左右就会成形。

For example, the caudal fin can make it rotate, and the pectoral fin can sense the speed, direction, temperature, etc. of the water.

如果未铺过鲫鱼的你一定会发现鲫鱼是不是很难捉的，因为它有自己的保护色不信你可以买一条来看看，它的上部——胸部是浅黑色的，下部——腹部是白色的，也许有的人会问这跟保护色有什么关系？如果你仔细观察一下就知道了。

Its upper part - the chest is light black, and its lower part - the abdomen is white. Maybe some people will ask what this has to do with the protective color? If you look carefully, you will know.

动物说明文作文 篇3

兔子是一种美丽的小动物，乖巧、驯良，很是讨人喜欢。它们虽然有时也吃一些肉渣，却不是肉食动物。常吃的是嫩草。它们面容清秀，眼睛炯炯有神，身体矫健，非常机灵。小巧玲珑的面孔，长长的两只耳朵显得格外美丽，瘦小的身体穿着一身雪白的外衣。

The rabbit is a beautiful little animal, cute, tame, and very pleasing. Although they sometimes eat meat scraps, they are not carnivores. They often eat tender grass. Their faces are beautiful, their eyes are bright, their bodies are vigorous, and they are very clever. Her small and exquisite face, long ears and thin body were very beautiful. She was wearing a snow-white coat.

兔子从不躲藏在大树上，它和老鼠一样经常在地下活动，在地下东跳西跑，活生生的像一个地下劳动者。兔子是在地下筑窝，摘果实，喝泉水。我们在平原地区是很少看见野兔子的，因为它们从不接近人的住宅，也不待在小树丛里，只喜欢信在地下的洞里。在夜晚走到效外去，也许你能看见兔子们在草地上跳着，互相追逐打闹的影子。

The rabbit never hides in a big tree. Like a mouse, it often moves underground, jumping around and running around, living like an underground worker. Rabbits build their nests underground, pick fruits and drink spring water. We seldom see wild rabbits in the plain area, because they never approach people's houses or stay in small trees, and only like to believe in underground holes. Walking out of the effect at night, maybe you can see the rabbits jumping on the grass, chasing each other.

兔子不吃窝边草，有人说。其实，这是它们自我保护的一种措施，兔子是为了让天敌们看不见它们的窝，情愿饿死也从不吃窝边的草。兔子不像熊以冬眠来过冬。它们十分警觉，只要有其它动物路过它们的窝，它们就会立刻跑到其它的洞中去。

Rabbits don't eat grass beside their nests, some people say. In fact, this is a measure of their self-protection. Rabbits want to make their natural enemies not see their nests, and they would rather starve than eat the grass beside their nests. Rabbits don't hibernate like bears. They are very alert. As long as other animals pass their nests, they will immediately run to other caves.

兔子通常一胎生4—6个，它们生下来是全身红通通的没有一根毛，像是一个个肉球，可是过上个20天左右它们全都会长出雪白的绒毛可爱极了，十分讨人喜爱。

Rabbits are usually 4-6 at a birth. They are all red without a hair, like meat balls. But after 20 days or so, they all grow snow-white fluff, which is very cute and adorable.

动物说明文作文 篇4

大自然有许许多多的`我感兴趣的动物，其中我最喜欢蛇。

Nature has many animals that I am interested in, among which I like snakes best.

蛇是两栖类爬行动物，有很多种：有水蟒、眼镜蛇、草蛇、海蛇、沙漠蝮蛇、猪鼻蛇……等等上万种。

Snakes are amphibious reptiles. There are many kinds: pythons, cobras, grass snakes, sea snakes, desert snakes, pig nosed snakes, etc.

我最感兴趣的是它们的嘴。有一次，我看电视，看见里面的蛇足足可以吞下一只很大的水獭。我想这小小的蛇怎么可以吞下比自己大好几倍的动物？于是我马上就上网查了查，原来蛇的上、下颚不像人的嘴后面有一个连接物，可是蛇没有，所以蛇可以随心所欲地张大嘴巴，这太让我吃惊了。

What interests me most is their mouths. Once, when I watched TV, I saw that the snakes inside could swallow a very big otter. I wonder how this little snake can swallow animals several times bigger than itself? So I immediately checked on the Internet. It turned out that the snake's upper and lower jaws did not have a connector behind the human mouth, but the snake did not. Therefore, the snake could open its mouth freely, which surprised me.

蛇的嘴让我感到很惊讶，但是蛇的毒更让我感兴趣。比如沙漠眼镜蛇，它一见到猎物就竖起脑袋来，颈部变得像一把扇子，舌头一吐一吐地非常可怕。而且如果猎物不理会的话，眼镜蛇就会从嘴里的两根管子里喷射出一种剧毒的液体，可以在40秒内毒死猎物，最远可以喷到两米之外的地方呢！我还知道的毒蛇有：死亡蝮蛇、响尾蛇、五步蛇、百步蛇、竹叶青等，有些蛇至今没有研制出抗毒血清。

I was surprised by the snake's mouth, but I was more interested in the snake's poison. For example, the desert cobra sticks its head up when it sees its prey, and its neck becomes like a fan, and its tongue is very terrible. And if the prey does not pay attention, the cobra will eject a highly toxic liquid from the two tubes in its mouth, which can poison the prey within 40 seconds, and can be sprayed as far as two meters away! I also know the following poisonous snakes: Agkistrodon halys, rattlesnake, five legged snake, hundred legged snake, bamboo leaf green snake, etc. Some snakes have not yet developed anti venom serum.

蛇的世界很精彩也很神奇，当然它也很可怕，所以我警告小朋友们，没事别招惹蛇呀！

The world of snakes is wonderful and magical, of course, it is also terrible, so I warn the children, don't provoke snakes if you have nothing to do!

动物说明文作文 篇5

我家有一只纯种金毛犬，它叫虫虫。它非常可爱，鼻子像一个小三角，耳朵像一把扇子。

My family has a purebred golden retriever, which is called Bug Bug. It is very cute. Its nose is like a small triangle, and its ears are like a fan.

它什么都吃，记得有一次我给它喂了整整一大碗红烧肉，它一会儿就把那红烧肉吃完了。它也喜欢锻炼身体，我每天早上都带着它去跑步，我跑着跑着，就没力气了，可它还在不停地跑着。它也喜欢帮助人，有一次我生病了，躺在床上不能动弹，虫虫看见了，马上把我的药给叼了过来，它又将妈妈叫起来，让她来照顾我。

He ate everything. I remember once I fed him a whole bowl of braised pork, and he soon finished it. It also likes to exercise. I take it to run every morning. When I run, I have no strength, but it keeps running. He also likes to help people. Once I was sick and couldn't move in bed. When the insects saw me, they immediately picked up my medicine. Then he called my mother up and asked her to take care of me.

虫虫也很爱撒娇，每当我放假回家，它就兴高采烈地来迎接我，我一蹲下，它就一下蹦到我怀里，在我身上蹭来蹭去，我一站起来，它就抱住我的腿，不想让我走。

Insects are also very coquetry. Every time I go home from vacation, they come to meet me happily. As soon as I squat down, they jump into my arms and rub against me. As soon as I stand up, they hug my legs and don't want to let me go.

虫虫也是我家的“守门员”，要是别人来到我家，它就会叫个不停，直到那个人走了才不叫。

Insects and worms are also the "gatekeepers" of my family. If others come to my house, they will keep barking until that person leaves.

虫虫也是个“调皮鬼”，我一将鞋脱掉，它就咬我的鞋，我让它松口，它还在咬，于是一场“人狗拔河”就开始了，我正占上风，可虫虫还不放弃，到了最后，我猛一松手，虫虫就倒在地上，一副“四脚朝天乌龟”的样子，看着真滑稽。

The insect is also a "mischievous ghost". As soon as I take off my shoes, it bit my shoes. I let it loose its mouth, but it was still biting. Then a "tug of war" started. I was getting the upper hand, but the insect did not give up. At last, I released my hand suddenly, and the insect fell on the ground, looking like a "turtle on all fours". It looked funny.
