动物狗英语作文【最新20篇】

一天， 妈妈给我买了俩只漂漂亮亮，小巧玲珑的小狗，可爱极了!

那是一个双休日的傍晚，天气十分寒冷。可我的被窝却是暖暖的。我们家的俩只小狗却冷的发抖，它们触到暖气，像箭一般地跑过来。蹑手蹑脚地在我床边，间了闻那暖气，小心翼翼地爬到了我的床上，钻进去鼓成了一个小圆球，舒舒服服的睡起了大睡。忽然，我的脚好像有冰，起来一看，床单湿了一大块，我很害怕爸爸、妈妈明天会骂我。于是就十万火急的下床，冷静一想：“我的裤子怎么没湿呀!”我慢慢地掀开被子吓了一大跳!原来是小狗!这时我的心才平静下来，我把抱下小狗来，气极败坏的把它们骂了一顿。从那时起妈妈给小狗买了件暖暖的衣裳。

以后小狗再也没冷过，我的床再也没湿过，看!这就是我家“淘气包”我爱我调皮的小狗。

I get along with it for a long time, in love, it seems very understand me. Whenever I am angry, it squatted beside me quietly motionless and seems to want to accompany me through the sad time. I am happy, it will run up to and around me, "an auf" cried, very agreeable.

In black, shiny hairs, eyes with two white spots, like two white beads. On the head and on his thighs hair is very long, like a horse head to the ground. Straight ear, as if time in listening to what passed around. Thick and long broom tail swing, from time to time as a cleaner for free! More funny is that it always speaks with a wet nose toward me, like a sick child, seems to be very poor, in fact, I know it really want to play with me. In the invitation to me!

The puppy experience dangerous also have several times.

And on several occasions by poison poison dog several times, but also by early treatment, will have to escape. From then on, it can sniff out those toxic food, what food non-toxic. Later, our dog never in poison. It very sharp!

The little black dog is my favorite animals, because it brings me a lot of laughter! Do you like my what?

问我喜欢的小动物是什么，那我会毫不犹豫的回答——我家的小黑狗!

小黑狗的性情很温顺，很通人性。

我和它相处久了，产生了感情，它好像很理解我。每当我生气的时候，它就静静地蹲在我身边一动也不动，似乎想陪我度过那难过的时间;我高兴的时候，它就会围着我跑来跑去，“汪汪汪”地叫着，很讨人喜欢。

小黑狗可逗人喜欢了!

一身黑亮亮的绒毛，眼睛上面有两个白点，颇像两颗白色珠子。头上和大腿上的毛很长，像马鬓一样拖到地面。直楞楞的耳朵，好象时刻在倾听着周围有什么动静。又粗又长的扫帚尾巴不时摇摆着，像一个免费清洁工呢!更逗人的是它总翘着潮湿的鼻子向着我，像一个生病的孩子，看起来似乎很可怜，其实，我知道它很想和我玩。在向我发出邀请呢!

小狗的经历危险也有几次。

第一次是掉进了河里，幸好被人发现拉了上来，喂给它吃药，不久就好了。还有几次是被毒狗的人毒了几次，幸好也被及早治疗，才得脱险了。从那以后，它就能嗅出那些食物有毒，哪些食物无毒。后来，我家的狗再也没中过毒。它够机灵吧!

小黑狗就是我喜欢的动物，因为它给我带来了许多欢声笑语!你们喜欢的动我是什么呢?

我家有一只可爱的小乌龟。那还是我10岁生日小姑从爸爸那里得知我喜欢小动物，便送了我一只稀罕物——小乌龟。

小乌龟托着一副有大又重的龟壳，四肢玲珑娇小的脚时伸时缩，一双小小的眼睛整天不停地转。

小乌龟十分贪吃。每天吃饭要按时定点吃饭，每顿饭还必须吃瘦肉，如果哪一天的哪一顿没有给它吃肉，它就会大发雷霆，把鱼缸中的水扑腾到哪里都是。所以我天天准时去喂它，早晨六点半要为一块小瘦肉，中午十二点半三块瘦肉，下午六点半二块瘦肉，在我的精心呵护下，小乌龟渐渐的长大了长得壮实了。

昨天爸爸妈妈带我去了动物园，我便把作息表改成早上7：00起床，自然喂小乌龟就改到7：10分了。浑身疲惫的我劳累地一觉就睡到了大天亮，正睡着香呢，突然，只听见一声“咣当”。呀!我的头，我坐了起来,看了一眼表“天啊!”到时间该喂小乌龟了，我向鱼缸里一瞧，小乌龟呢?我四处打量了一下，原来小乌龟正在我床上散步呢!敢情小乌龟饿了，它竟然从鱼缸里爬了出来，砸在我头上向我抗议呢!

从此以后，我想我可不敢再晚喂小乌龟了，可爱的小乌龟呀!你说说我是喜欢你呢，还是讨厌你呢?

我可爱的小乌龟!

有一回，妈妈带我上姥姥家去，路上我看到一条小狗。我见这条小狗非常可爱，就从妈妈的车上跳下来，慢慢走到小狗的身边。这时不知从哪里走过来一个人，她问我：”这小狗是你家的吗？”“是啊!豆豆走吧!”我脑子灵机一动，想出了个名字，随口就说。

望着那个人远去的背影，又看看这只小狗，我想把它带回家，因为我太喜欢这只小狗了。

我边往姥姥家走，边回头瞅着小狗，招呼它和我走，可是它只是望着我，就是不和我走。我便假装慢跑，边跑边回头，小狗以为我和它逗着玩，就慢悠悠地跟着我跑过来了。

这时不知从哪里又出来一个大男孩，他问我：”这小狗是你家的吗？”我冲他点点头，假装真的似的。可是那个男孩就是不信，还和又不知从那冒上来的一个阿姨说：”妈妈，这不是谁谁谁家丢的那条狗吗？”我有点急了，眼看就要成功的事了，不能就这样白白泡汤了。我大声说：”不是!”他们看我这样着急了，就相信了我。我便带着小狗往姥姥家走去。

我害怕小狗再从我身边走开，边走边想办法。我看见路边有一家抻面店，便过去向店主要了三块小瘦肉丁。我先扔给小狗一小块，让它看看我手里还有两块肉。然后往前走。小狗吃了一块以后，就摇着尾巴跟着我小跑起来。我带着它走到姥姥家的楼口，让它跟我上楼。看着他一跳一跳地跟着我上楼梯，我真高兴，又给了他一块。他香喷喷地吃下去，摇着尾巴又跟我走，一直上到姥姥家的门口，等姥姥打开门，小狗跟我进了屋，我才把最后一块小肉丁给了它。我赶快关上门，这条不是我们家的可爱的小狗就被我用计策带了回来。

虽然我很快就送还给为丢狗着急的李奶奶，还是觉得它带给我难忘的快乐。

狗是这个世界上较大的物种，它是动物类当中最聪明的动物，非常讨人喜欢。

狗的种类很多，我们常见的有狼犬、牧羊犬、宠物狗，宠物狗有几千种，它体形非常小，颜色很纯，有黑、白、黄它也很聪明，天天快活的不的了，如果受人训练的话，它就会学人的动作表情。宠物狗还能看家，如果有人来了，它就会汪汪的叫，给主人发出信号，让主人知道有人来了。它还会哄人开心，如果你愁眉苦脸，让宠物狗看见了，它就会爬到你身上，用爪子摸你。战獒身形庞大，是宠物狗身体的十倍，如果战獒是一棵高大橡树，宠物狗就是一棵娇嫩的小草，宠物狗的凶猛力是战獒的百分之一。牧羊犬可以替人来放羊，这种本能是宠物狗不能及的。我和我家的宠物狗有许多有趣的事，有一次，我到姥姥家去，我把宠物狗也带去了，我到姥姥家后，就开始玩小猫，宠物狗在炕上趴着。到了晚上，宠物狗拿爪子打我胳膊，一脸可怜的样子。原来今天上午我玩小猫，小狗吃醋了。

我喜欢狗，因为狗给我带来了许多快乐！

Animals are friends of human beings. Most of them are lovely. I like giraffe the most.

They are very tall and have many brown spots. They have very long necks, so that they can eat the leaves in high trees. Giraffes are gentle and lovely.

They are friendly to people. When I go to the zoo, I always look at them. They move slowly.

I can’t keep it as a pet, because it’s so huge. It’s a big pity.

I have a lovely puppy. Its name is "Huanhuan", 2 years old this year, with my birthday is the same day.

Huanhuans body is about fifty centimeters long. Its hair is white and long, plush, feels like a mass of cotton. Its head and the ball is about the size of a pair of black eyes like two black pearls. The tail is thick and long.

Huanhuan like me Morning, I went to school, the dog always bowed his head, as if unwilling to let me go like. I went to it and said to it: "I want to go to school, and then play with you at noon!" After school, my first thing is to feed welcome, every time I was holding the food by hand to stay in it The head, she will use two legs to the ground, the body upright, the food swallowed, finished. I said, "Handshake." It put the little claws on my hand and kissed me earnestly. When I sleep, I sometimes use my hot tongue to lick me up.

I like the puppy.

It is suggested that people have been aware of the issue--lack of preservation for endangered spieces, animals and plants, but as you see , they placed little efforts to cope with the problem.despite the versatility and intricacy of instruments , I would pore over some of the most striking ones and offer alternatives afterwards.

这表明人们已经意识到这个问题——濒危物种保护的不足，动物和植物，但正如你所看到的，他们把小的努力来应对problem.despite的多样性和复杂性的工具，我会在一些最引人注目的和提供选择之后。

One of the major reasons , causing peoples inocence of protecting animals, is that the government did not function well as an educator, arosing peoples initiative in shielding wild animals, which led to the consequence that people do not know their responsibility to prevent animals from dangers, and specific knowledge in guarding them. what is equally important as the reason mentioned above is that media did not meet our satisfaction to inform the mass of the emergency which is crutial in arousing peoples conciousness to keep animals safe.

其中一个主要原因，引起人们的灵感保护动物，是政府不作为一个教育工作者的作用，调动人的主动性保护野生动物，其中LED的后果，人们不知道他们的防止动物从危险责任，和看守他们的具体知识。同样重要的是上面提到的原因是媒体没有我们满意通知紧急，唤醒人们的意识使动物安全是重要的质量。

In spite of the serious problem, measure leading to profound improvement still can be taken. owning to the fact that funds are insufficient in some developing countries, developed countries or international organizations should shoulder more burden -- finacing them in order to capacitate them to accompolish the protection of animals. at the same time, education in telling people the way to make animals harboured ought to be focused on, thus resulting in peoples better awareness in the camouflage of our planets cutest creatures.

尽管在这个严重的问题，导致深刻的改善措施仍然可以采取。由于资金不足，在一些发展中国家，发达国家和国际组织应承担更多的负担——融资以使他们实现保护动物。同时，在告诉人们如何使动物怀有应该集中在教育，从而导致人们更好的认识在我们星球上最可爱的生物的伪装。

It is belived by me that if correct actions are taken to preserve animals, any kind of them will be far away from extinction forever.

这是我认为，如果采取正确的行动来保护动物，任何一种他们将永远远离灭绝。

我家有只小狗，是我妈妈在我生日的时候送给我的生日礼物，我很喜欢它，妈妈给它取了个可爱的名字叫旺旺旺。

My family has a puppy. Its my mothers birthday present to me on my birthday. I like it very much. My mother gave it a lovely name.

每天我放学回来第一件事就是拿东西去喂旺旺，我妈妈说过，要和小狗做朋友，就必须要好好的对它。

Every day I come back from school, the first thing is to take things to feed Wangwang, my mother said, to be friends with the puppy, it must be good to it.

所以，我平时还会帮它洗澡和带它出去玩。旺旺可调皮了，一开始每次帮它洗的时候，它总是不愿意，每次都会把我的衣服弄湿，但我也没生气，妈妈说过，多帮它洗几次它就会习惯了。

So I usually shower it and take it out to play. Want to be naughty, and at the beginning of each time to help it wash, it is always reluctant to, every time I wet my clothes, but I did not angry, mother said, and more help it wash a few times, it will get used to it.

每天晚上吃完饭，我就会牵着小狗和妈妈一起到外面散步，带它到公园和其他的小狗仔一起玩，可是旺旺太淘气了，整天欺负隔壁的阿王，妈妈就说，以后不带它出去了。旺旺虽然有点淘气，可是我还是很喜欢它，我要永远和它做朋友。

Nowadays there are so many animals out there make people in real life happier. Dog is the best example to identify. As many people believe dog is mans best freind, this is very true.It not just entertain us, however, sometimes dogs could actually help their owner do some work!

When we are bored, we might take our dogs for a walk, we could play with them. Mainly dogs listen to their owner all the time, they are most obedient pet out of all kinds of animals.Peeple like dogs simply because, they are cute, they make fun of us and most significantly, dogs make people happier. Therefore, saying dogs are peoples friend have nothing wrong, they actually obtain the most closest relationship with the human beings out of all animals.

Not long ago, my family came a "gentleman", it was covered with plush, much like marshmallow, so sometimes I called it marshmallow, did not think it, it is our new members, a puppy, Its name is called white, its long ears to cover half of the face, eyes round yo, like two black pearls. White happy time, always thrown the tail, making mistakes, always sandwiched tail under the table or under the bed, afraid of others to fight it.

Eat when the white is always the small head buried in the iron wrist, arching iron wrist straight circle. It is very greedy, like a goldfish, will only eat, do not know full, once, it eat too much, the whole stomach bulging, like a frog, had to obediently lying on the ground a move can not move. When we were not at home, it made a mess of the house and torn the paper at home. It shoes to other places or bite the shoes. Once, it took my sandals out to the door, causing me everywhere could not find.

White like to go with people, my father and mother called it with stooge. It also likes others to touch it, others touch it when it obediently lying on the ground to touch.

I like my familys puppy because its funny and it brings a lot of laughter to our house.

我的名字叫狗，我可以自豪地说，我是全世界上最有灵性、最聪明的动物。我最喜欢吃东西就是狗粮和肉骨头了。

如果有人伤害我或着我的主人，我就会让你吃不了兜着走。嘻嘻！不过我对我的主人绝对忠诚，她给我肉骨头吃时，我会用嘴巴在她的腿上蹭蹭，表示我的感谢。

当我还是婴儿的时候我才有500克，长15厘米，等我长大了一些，耳朵如果是竖立起来的，我就是个帅帅的小男生，如果耳朵是垂下去的，我就是个漂亮的小女生。

等我是成年的狗时，人们就把我训练成警犬，主人每天都带我巡逻，如果我完成任务，还有好吃的和小球玩呢！

This fish earned its name by utilizing evasion as a way to escape its predators. It bodily leaps from the ocean, reaching a speed of about 35 miles per hour and a recorded gliding time of up to thirty seconds. This can take them as far as 200 meters from their point of exit from the water, which may be far enough to escape pursuit or confuse predators. Fishermen favor these types of fish, but due to their sheer numbers in the wild, none of the 40 different species of flying fish are listed as endangered. While they can be found foraging seasonally along the outskirts of warm water reef complexes, flying fish are primarily pelagic, and favor tropical or subtropical open waters around the equator.

飞鱼得名于它独特的避难方式。遇到捕食者时，飞鱼会采用一种独特的逃跑方式：它会纵身一跃，跳出海面。此时它的速度可达到每小时35英里，在空中滑翔长达30秒。这一跃能使它们飞行200米，足以使它们全身而退或者迷惑捕食者。渔民们很是钟爱这种鱼，野生飞鱼数量众多，所以40种飞鱼中没有一种濒临灭绝。人们发现飞鱼有时会季节性的在温水区近郊地带的杂礁灰岩附近觅食，不过它们属浮游类鱼类，喜欢在赤道附近的热带，亚热带地区的公海活动。

Subsisting mainly on a diet of plankton and small marine life, flying fish are schooling fish that hunt primarily at night. While some sources may find this counter-intuitive, given the ease with which the fish are drawn to light sources, this actually makes perfect sense. Many of the plankton and marine resources the fish favor are slightly luminescent, especially by moonlight, making them easily seen in the darkness. This also provides cover, given the coloration of the fish—blue or grey on top, silvery white on the bottom—so that they are not easily seen from above or below as they feed on the clouds of marine flora. Flying fish generally mate during the autumn or spring, when currents are at their weakest. Females will deposit their eggs on the surface, attached to flotsam, and males will fertilize the eggs. Schools at this time can number in the millions, and constitute a major resource for species that feed on the fish. Because they only tend to live about five years in the wild, their flesh is prized for its purity—free of the heavy metals often found in longer-lived species.

飞鱼主要以浮游生物和小型海洋生物为食，主要在夜间以集群的方式进行捕食。有些人会觉得下面这个说法有悖常理，因为鱼类易被光源吸引，这么说也不无道理。许多浮游生物和鱼类自身都会发出微弱的冷光，尤其是在月光照射下，更是清晰可见。但这同时也为鱼类提供了一层防护，让它们有了保护色：一般在上部会呈现蓝色或灰色，下部呈现银白色。凭借这些保护色，当飞鱼在海底植物中进食时就很难发现它们。飞鱼通常会在春秋时节进行交配，因为这个时期洋流的活动最为和缓。雌性飞鱼会将卵产在海面上，让其依附在漂浮物上，雄性飞鱼再让鱼卵受精。此时在飞鱼的集群中，会有数以百万的成员。而这也为以鱼类为生的动物们提供了主要的食物来源。由于野生飞鱼只有5年的寿命，它们不会像长寿的鱼类一样体内留有大量重金属物质，因此飞鱼肉被人们视为珍品。

I have always enjoyed the puppy, the puppy to grandmas house is particularly like, remember once I back to grandmas house, the dog seemed to think I am the bad guy, keep the eye, or grandma picked the dog away.

小狗在追人时，眼睛会有一道可怕的眼神，好像心中有一颗大火球，快要爆炸了!当它在吃东西时，它就会很温柔的蹲下来，一下子又变成一位优雅的天使了!当它要大号时，它会跑去树旁边挖洞，并用泥土把它的粪便埋起来，真像是一位聪明的老师呀!

下次如果有机会，我一定要把这只超特别的小狗带给大家看，我相信你也会喜欢他喔!

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

I have a parrot. Its name is Nancy. I call it Nancy， because it is my passed grandmother’s name. I love her and hope she can accompany with， so I name my parrot her name. Nancy is very beautiful. Its fur is special comfortable. It is clever， too. At first， it can’t say any words， but now it can say many words. Like， good morning， good afternoon， good night， good bye and so on. it learns fast. I love it very much.？

我家有一只狗叫贝贝，样子像一匹威风凛凛的狼，陌生人见了，都很怕它。

它的毛是土黄色的，在阳光底下油光发亮。它有一对三角形的耳朵，一听到动静，耳朵就会竖起来。一双黑溜溜眼睛就四处张望。它的身子后面还有一条长长的尾巴，如果主人走过去，它的尾巴就会摇来摇去表示友好。它还有四条腿，跑起来十分快，犹如一道闪电。它的力气很大，有一次，外婆牵着它去散步，它拼命地往前冲，差点把外婆拽倒。别看贝贝样子很凶，其实它乖巧着呢。

有一次，贝贝生病了，它有气无力地躺在狗窝里，不吃也不喝，显得很没精神，我和外波婆决定带贝贝去看病。

我和外婆牵着贝贝来到兽医院，贝贝看见穿着白大褂的兽医走过来，竟然像个胆小的孩子似的，撒腿就跑。幸好我把铁链拉得紧紧的，才没有挣脱掉。我摸摸贝贝的毛，又摸摸它的头说：“乖，要听话，不打针不吃药，病怎么会好呢?”贝贝好像听懂了我的话，这才乖乖蹲下身子来。兽医拿着针筒抽好药水，准备给贝贝打针，我想：“贝贝如果不听话，咬兽医一口怎么办啊?”我不禁提心吊胆。开始打针了，兽医拍了拍贝贝的身子，示意它别动，再把药水打进贝贝的身体，贝贝竟然不吵也不闹，连一声也不叫。

贝贝真是只乖巧的狗。
