猫是一种漂亮的小动物，它乖巧、驯良，很讨人喜欢。它长着一个小巧玲珑的小面孔，上面有一双蓝宝石般的大眼睛，还有一个红扑扑的小鼻子，它虽然是食肉动物，可是长得一点都不像凶猛的食肉动物。猫也是哺乳动物，它是胎生的，小猫靠吃母亲的奶长大。家猫可以在人类的休息常所生活。那野猫呢？野猫一般生活在草原上，靠草原上的草来隐蔽自己，猫身手敏捷 ,在野外猫靠敏捷的身手来捕捉在草丛飞鸟，其实家猫也是被野猫训化过来的。许多人说猫怕水，不敢下水。其实猫也敢下水，也可以游泳。不过那只是生活在野外的猫。猫是一种非常干净的小动物，不管去到那里身上都是干干净净的，滑滑的。世界是最小的猫只有钢琴键那麽大，才两厘米。猫很机警在休息或睡觉的时候一听到什么声音就立刻起来左看看右看看放心以后就在休息。猫一般生一至两只幼崽，把他们哺育大。

小狗是人类的好朋友，很多人都非常喜欢小狗。你有养过小狗吗?如果要描写小狗，应该怎么写呢?下面就是小编给大家整理的写小狗的优秀作文精选，希望大家喜欢。

写小狗的优秀作文一

小狗在日常生活中。我根本没有观察过它，今天我就要当一回观察大兵。

首先小狗的爪子不怎么锋利，但爪子比牙齿锋利一些。说到锋利，它的牙齿到底有多锋利呢?我去测试一下吧。我给了它一个小东西，那个东西我可咬不开一点缝隙，看看小狗能不能咬开。过了一会儿，小狗“咔嚓”一声把那个小东西吃掉了。真是太不可思议了。它的毛摸着很舒服，就像摸着棉花一样舒服。小狗的尾巴很像一大丛狗尾草。小狗的眼睛特别有用，因为它饿了的时候用那会说话的眼睛望着我，好像跟我说:“主人，主人，我饿了，能不能给我东西吃呀?”我也只好喂东西给它吃了。

小狗睡觉的时候是爱趴着睡。小狗的耳朵很尖，它还没睡着的时候，只要你脚步较重一点地从它面前走过，它就会立刻张开眼睛。

它最爱吃的就是骨头了。当然也喜欢狗粮等食品了。有一次我捡了一个塑料做的骨头扔过去，它闻了一下就走了。小狗最爱跟我玩扔飞盘了。我把飞盘扔了出去，小狗在飞盘还没落地的时候，就已经接住小狗一见到我了就像我遥尾巴，一听到我的声音就来迎接我。小狗一见到陌生人就“汪汪汪”地叫个不停。

这就是我喜爱的小狗，这就是喜爱我的小狗。

写小狗的优秀作文二

今天，我回奶奶家观察了小狗，小狗可真可爱!

小狗的身子矮小，毛黄澄澄的，走起路来像一个滚动的小绒球;大大的眼睛像两颗宝石，湿渌渌的;趴在地上睡觉时，小耳朵耷拉着，看上去像一只大懒虫;它那条又细又短的小尾巴摇摇摆摆的，十分惹人喜爱。

小狗是人类的好朋友，这句话一点不错。有时你只要呼唤它一声，它立刻就会赶过来，绕着你的腿转，然后扑到你身上，用舌头舔你，用身子蹭你。有时你玩球时一不小心把球弄丢了，小狗就会跑过去，它的鼻子就像气味探测器似的到处找，不一会，小狗口里就叼着球回来了。

小狗的性格也是天真可爱。有时它跟小猫打斗，我就训斥他，无论怎样打它骂它，它也不叫，更不会咬你，就像一个做错事的孩子一样老老实实地呆着。

养小狗真好，还能节约粮食。每当我们吃剩的饭菜倒掉了一是觉得可惜，二是污染了环境，可是有了小狗就不一样了，它可以来吃剩菜剩饭，既环保，又充饥。它不但能帮忙看家，更像我的朋友一样与我分享快乐。

写小狗的优秀作文三

暑假的一天，我在楼道口发现了四只小狗。它们的个头那么小，像四只圆滚滚的肉馒头，可爱极了。我决定每天放学都去看看它们。

第二天，我兴冲冲地来到楼道口，发现有一只小狗已经死了。糟了，一定是没有人喂它们吃的。我难过极了，再也不想看到小狗死亡，于是，我决定每天都给小狗带狗粮来。就这样，我当了几天“代理狗妈妈”。

一天早晨，我走得太急，忘了带狗粮。我想回家拿，妈妈说：“放心吧，发现你没带狗粮，爷爷会帮你喂小狗的。”我只好去学校。这一天我过得忐忑不安，一放学就往家冲。冲到楼道口一看，我简直不敢相信自己的眼睛，小狗又死了一只!我的眼睛一下子涌了出来，我把剩下的两只小狗紧紧地抱在怀里，下定决心，无论如何都要收养它们。

经过我的一番“眼泪攻势”，妈妈总算同意放小狗进门。我给小狗取了名字，全身乌黑的那只叫孙小圣，灰色的那只叫镇元子。它们可爱极了，特别是见到食物的时候。只要我端着狗食盆叫它们的名字，它们就立刻“健步如飞”，冲到我面前，又是打滚又是摇尾巴。当我把食盆放下时，它们就展开了“狼吞攻势”，大吃大嚼。看到它们吃得津津有味的样子，我也很高兴，总是忘记妈妈“不要让它们吃得太饱”的叮嘱，忍不住又给它们添点儿。所以，如果现在你到我们家，就会看到它们像小猪一样“丰满”的身材啦!

写小狗的优秀作文四

外婆家有一只可爱的小狗。它的毛很光滑，乌黑发亮，眼睛圆圆溜溜的，像两颗黑珍珠，后腿长，前腿短，爪子也很尖，跑起路来又轻又快。

每次，我一回到婆婆家，这只小狗就会摇着尾巴一边汪汪地叫着，一边在我身上亲来亲去，向我表示欢迎呢。

小狗的警惕性很高，不管天有多黑，他都能看清周围的事物。有一次，天已经很黑了，有一个陌生人来外婆家，小狗看见了，就大叫起来，边叫边往那人身上扑去。我一看，就赶紧上楼叫婆婆，婆婆一看，原来是客人。小狗看着婆婆热情地招持客人，好像明白了什么似的，又好像给客人道歉似的，不停地拿舌头舔那人的裤腿。

小狗吃鱼还会吐刺呢。有一次，外婆给我炒了一盘鱼，我香喷喷地吃着，小狗蹲在我面前眼睛直勾勾地看着我吃，馋得一个劲地舔嘴唇，于是我就夹了一条给小狗，心想：扎你一回，看你还眼馋不。没想到，它吃得可香了，不一会儿，就把鱼给吃完了。我仔细一看，地上有一堆鱼刺，感到非常惊奇，原来这只小狗还会吐刺呀!

我想：多么神奇、可爱的小狗呀!

Last summer holiday I went to Paris with my parents by plane. First we visited the Arc and Triomphe, and we took many photos. Then we went to the Notre Dame, which is very wonderful. We saw a lot of interesting things. Finally we came to the Eiffel tower, and there were so many people, but they were all friendly. After that we sat on the grass, looking at the view. We felt very happy.

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。

Most kids like animals. Girls like cats, and boys like dogs. However, my favorite animal is the horse.

The horses are strong, not like the tame cats or puppy dogs. They look wild and hard to get close. Yet, they will be very timid and friendly after they get to know you. Horses remember the way home. They are also faithful to their masters. They even understand what you are trying to tell them. Ive heard many stories about how a horse saved his masters life. Thats also the reason why I love horses. They never betray you.

大多数孩子喜欢动物。女孩喜欢猫,和男孩喜欢狗。然而,我最喜欢的动物是马。
