在一个炎热的夏日，我正在家里看电视，突然传来一阵敲门声，我开门一看，原来是爸爸回来了，他手里抱着一个小箱子。我急忙问爸爸箱子里装得是什么东西，爸爸让我自己看，啊！原来是两只可爱的小狗。爸爸告诉我说：这是两只日本白狐狸狗，才出生20天，一只公狗；一只母狗，是爸爸的同事送给你的。我抱出两只小狗仔细的端详。

现在两只小狗长大了，我和它们的感情也越来越深了。你们是不是也想一只这样的小狗呢？

Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

Allen （not his real name） is driving north out of Virginia in the middle of the night， with stolen property in the back of his van. But Allen isn‘t a criminal – in fact he normally would never dream of breaking the law.

The “property” he stole is a dog he calls Flash. Allen doesn‘t particularly want Flash – in fact， in a few hours he‘ll drop him off at a stranger‘s house and never see him again. “I couldn‘t just stand by and do nothing，” he explains. “The owner was plainly neglecting the dog， but the police wouldn‘t do anything about it.”

For over a year， Flash had been tied to a tree in front of someone‘s house. “He was sick and malnourished，” says Allen. “More than once I saw [the owner] kick him for no reason at all.” Allen had repeatedly tried to get the owner to take better care of the animal， or to give it away to someone who would. Finally， he took matters into his own hands – in the dead of night， he took Flash off his chain and drove away with him.

Within an hour， Flash had a new license tag and was being treated by a veterinarian who knew better than to ask questions. Pictures of the dog were put up on animal rescue websites， asking for someone to adopt the dog. A couple in New York offered to take the dog， and animal lovers in states along the way agreed to provide transportation.

Nobody can say for sure how many animals like Flash are ‘rescued‘ every year – receiving stolen property is a crime， so rescuers tend to stay in the shadows. But a growing number of empty collars attests to their work as more and more animals find their way to loving homes.

我是一只世界上最小最小的鸟儿，蜂鸟？没错，我就是一只蜂鸟。我又被人类称为“神鸟”、“彗星”、“森林女神”和“花冠”。

我们蜂鸟最早的祖先生活的时间比现在早了三千多万年。而我们之所以被称为蜂鸟，是因为我们大小跟蜜蜂差不多，又跟蜜蜂长得有点儿像，而且我们都是靠采蜜为生呢！

虽然跟蜜蜂相似，但我们也有不同的地方，蜜蜂一般都是黄褐色的，而我们蜂鸟却五彩缤纷，有蓝绿色、紫色、红色、黄色等等。我们的嘴又细又长又尖，舌头像一根针，翅膀有点透明，呈三角形状，尾部羽毛较长。

我们虽小，但我们可是飞行能手，可以运用自如地上升、下降，向前、倒退，往左、往右，还可以像直升机一样停在半空中，而且我们采蜜、捕昆虫都是这样悬着的呢。

虽然我是最小的鸟儿，体长只有六厘米，约重四克，()但我们蜂鸟有六百多个种类，记得我有一个叫“巨蜂鸟的同伴，它体长二十一厘米，当然不是世界上最小的鸟儿了。

我们的翅膀拍得特别快，新陈代谢是所有动物中最快的，心跳每分钟最少有两百多下，最多有一千两百多下，很惊人吧。

关于我们蜂鸟的事还有很多，如果有兴趣的话，可以到加拿大、火地岛、南美州等我们分布的地域来，更全面地了解我们。

[二年级作文描写小动物

初识大熊猫，是在四川的动物园里，时隔七八年，但是看到大熊猫的模样已经记不清了。

不过在电视里经常可以看到大熊猫憨态可鞠的样子，总让我感到亲切。

它是那么的可爱，胖嘟嘟的身体上是黑白相间的毛外衣，这使它即使在严寒的冬天也不会感觉到冷。

特别突出的是那双标志性的熊猫眼，仿佛永远也睡不够似的。

直到学习了《在大熊猫的故乡》这篇课文，我对大熊猫的习性有了更深的了解。

老师的问题让我联想到今年要送给台湾的那两只“国宝”——团团和圆圆。

它们的名字是从千百个名字中竞选产生的，为什么给它们取这个名字呢?这其中是有着深深的含义的。

在中日甲午战争时，日本强行与清政府签定了不平等的《马关条约》，台湾沦落入日寇的魔掌，抗日战争胜利后，台湾又一直为所盘踞。

在香港澳门相继回归后，台湾并没有回归祖国母亲的怀抱，原来台湾当局一直想搞独立。

现在，人民政府赠送两只大熊猫给台湾，并取名为“团团”“圆圆”，意思就是要台湾和大陆团团圆圆，早日实现祖国的统一。

我在网络上浏览过团团圆圆的照片，它们憨实、可爱，的确就像是两位和平大使，我希望它们能传达祖国人民的无比情谊和殷切的期望，为祖国的早日统一牵线搭桥。

今天上课前，老师突然问我们：“你们知道大熊猫吗?”“知道!”同学们异口同声地答道。

接着，大家就七嘴八舌地议论起熊猫的特点来。

轻的泪，是人的泪，而动物的泪，却是有重量的泪。

那是一种发自生命深处的泪，是一种比金属还要重的泪。

也许人的泪中还含有虚伪，也许人的泪里还有个人恩怨，而动物的泪里却只有真诚，也只有动物的泪，才更是震撼人们魂魄的泪。

我第一次看到动物的泪，那是我家一只老猫的泪，这只老猫已经在我家许多许多年了，也不知它生下了多少子女，也不知它已是多大的年纪。

只是知道它已经成了我们家庭的一个成员，我们全家人每天生活的一项重要内容，就是和她一起戏耍。

在它还是一只小猫的时候，我们引得它在地上滚来滚去，后来它渐渐地长大了，我们又把它抱在怀里好长好长时间地抚摸它那软软的绒毛。

也是我们和它亲热得太多了，它已经一天也离不开我们的抚爱，无论是谁，只要这一天没有摸它一下，就是到了晚上，它也要找到那个人，然后就无声地卧在他的身边，等着他的亲昵，直到那个人终于抚摸了它，哪怕只是一下，这时它也会心满意足地慢慢走开，就好象是它为此感到充实，也为此感到幸福。

Our life will change greatly in the future.

In the future,every family will own at least one computer,with which we can shop online without going out.

That is really fantastic.Also,robots will be employed by every family.They can help do much of the housework.

Therefore family members will have more free time to spend time together.

In the future,kids dont need to attend school any more.

There is internet access in every family,with the help of which kids can study by themselves.

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!

小老鼠

我家养了一只小老鼠，它的名字叫乐乐，一听这名字就知道它是母的。

小老鼠的“衣服”可漂亮了，它身穿黄白相间的黄大衣，耳朵是灰色的，在它那黑亮的眼睛下有着一张小巧的嘴，小嘴里还有小小的牙齿。

小老鼠吃东西的时候很可爱。一天，我去看小老鼠，它好像感觉很饿，有气无力的，于是，我拿一大片嫩树叶给它吃，它看见一大片树叶，马上跑过来快速地吃起来，它三下五除二，一下子就吃完了，可它还没饱，还继续望着我，于是，我再拿几根面条喂它，我把面条放在它嘴边，它用爪子抓住面条快速地吃，我想逗逗它，就把面条向它后面漫漫地动，它好像受不了了，连连往后退，就像跳芭蕾舞一样，让我哈哈大笑起来。

小老鼠玩的时候也可爱，我经常躺小老鼠和我朋友的小老鼠一起比赛，可小老鼠似乎不愿意，不过我有法子，因为小老鼠要天天吃东西，不吃它就难受，所以我可以用树叶来引它，果真有效，小老鼠看见树叶真的跟着我来了，就这样很快地就到了重点。

你看，我的小老鼠可爱吧!

长城是中国的标志， 是中国人的骄傲

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。

导语：由于鲨鱼的嗅觉极为灵敏，非常容易地嗅出它们害怕或厌恶的气味。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

A new high-performance swimsuit,developed by mimicking the skin of sharks,will be worn by top athletes in Athens from this week.

The revolutionary new fabric,developed by Speedo,is the result of four years of research and development that began with the study of shark skin at the Natural History Museum .

The new swimsuit,called Fastskin FSII,increases a swimmers speed by reducing passive drag through water by up to 4% more than the next best swimsuit.

Research into shark skin texture and movement through water was carried out under the guidance of Natural History Museum fish expert Ollie Crimmen.

Tiny teeth cover the surface of a sharks skin and the shape and positioning of these teeth vary across the body to manage the flow of water.

With these findings Speedo created a full bodyskin with different fabrics on different parts of the body and for the first time,male- and female-specific and stroke-specific swimsuits.

I have a few small goldfish, they are lively and lovely, I like them very much. Small goldfish small and exquisite, there is a pair of grapes like big eyes, maple-shaped tail, the back of the fin fins to it that gold body fitted with a beautiful big fan.

Little goldfish eat very special. Once, I put a few fish food thrown into the water, a few fish met, quickly swim up to compete for fish food. I thought they would swallow up immediately, but their actions surprised me: grab the food of the fish first in the food in his mouth, and then spit out the food, and then swim up to catch it with the mouth, and finally The food completely swallowed it in the stomach. Where is the food, it is clear in the game it!

Little goldfish sleep more interesting! One night on the night I secretly got out of bed, by the outside of the faint light to see the small goldfish, found that small goldfish motionless, eyes also greatly open. I thought: they will not die! So knocked on the fish tank, a few small goldfish but quickly wandered. I suddenly realized, remembered the previous mother told me: "fish is no eyelids."

One morning, when I had breakfast, I went to see them. There are many small goldfish feces floating in the fish tank, the water has been turbid, and that they change the water. I carefully put the fish tank to the pool side, want to catch the fish ready to clean the basin. I was about to reach into the fish tank, my mother immediately stopped me: "Go and wash your hands, your hands have the taste of hand cream, will kill the fish!" I quickly wash your hands, and then stroked the sleeves, Began to catch fish. Hey! Fish really flexible, while fled to the east, while the channeling west, but how can not escape my palm. I was proud of it, "rip" it slipped away, I spent a lot of effort, and finally all the fish into the basin of water. And then the fish tank in the dirty water drained, and rinse, and finally the pot of fish and water poured into the fish tank.

Small goldfish really interesting! I think, as long as careful observation, after their own will find the little goldfish more special.

I like dogs, because they are man s good friends. They can do many helpful things to us, such as guarding our houses, greeting guests, helping the police, and so on. Some trained dogs can even lead the blind people and save people s lives. So they re treated as our family members. I hope someday dogs will be in great harmony with human-beings.

我喜欢狗，因为它们是人类的好朋友。他们可以为我们做很多有用的事情，如，保护房子，问候客人，帮助警方等等。一些受过训练的狗甚至可以引导盲人、拯救人们的性命。所以他们都被当做是我们的家庭成员。我希望有一天狗能与人类和谐共处。
