关爱保护野生动物

全文共 1025 字

+ 加入清单

动物与我们人类一样,有思想,有感情,也有它们自己的生活方式,更有自由权。

我们在未经动物们的同意之下就随意破坏它们的栖息地;在未经它们的同意之下就随意伤害它们的躯体;在未经它们的同意之下就私自决定它们的死亡。我们是否有考虑过它们的感受,是否有想过它们的想法,是否想过他们的生命什么时候终结是有他们本身决定的呢。

我们人类现在正提倡珍爱生命,爱惜生活。我们人类的生命很珍贵,难道动物的命就不值得珍惜么。或许我们人类也有不想死但是没有选择权利的时候,但是这样的事情毕竟是少数啊。我们就不能把动物当成是我们人类的一份子,当成我们的朋友,当成我们的家人一样对待么。

我们现在的生活水平越来越高,信息越来越发达,对物质生活与精神生活的要求也越来越高。但是我们的物质生活中可否将“食用野生动物对身体有好处”这一条去掉呢。现在有说吃野生动物可以长命的;也有说吃野生动物有营养的;更有人说吃野生动物对大脑有好处的。我想这个可能是对的,但是人类不能盲从,有些动物体内是有致癌物质的。

况且不说这个,就算野生动物吃了对我们有好处,但是人类有没有想过,当我们在尽情的虐杀它们的时候,我们人类的死期也快临近了呢?我想只要是读过书的人都对“生物链”这个词不陌生吧?一旦生物链被破坏,就意味着生物大家族会以最快的速度在地球上消失,最终人类也会落到死的下场。等到人类得到报应的时候,恐怕已经没有挽回的余地了吧?谁都知道一句至理名言——世界上是没有后悔药买的。为什么知道这句话,就不能去思考一下,去想一下,去实行一下呢?只要我们时刻记着这句话,时刻想着要去把它实践下去,当我们在餐桌上看到那无辜的生物的时候,还会开开心心的想要把它们吃下去吗?还会犯这么天大的错误么?

现在全球的动植物物种正在以最大的速度从地球上消失,有时候甚至每分钟都会消失一个物种。如果再以这样的趋势进行下去,人类难道不会消失么?人类难道就不能设想一下吗?难道就不能为以后做下打算么?难道就不能为后代打算一下么?难道就不能为人类的长远发展做下打算么?我们现在的生活幸福美满,不求吃穿,信息高速发达,这些都是我们的祖先留下来的,这些都是他们辛苦努力奋斗得来的。作为后代,难道我们要把他们的成果就这样毁于一旦么?我们后代就这么没有素质么?一定要把他们的成绩毁灭么?

地球就这样毁灭,人类难道不会觉得可惜么?

所以,为了人类的长远发展,好好珍惜保护野生动物,珍惜我们美满的生活,把祖先留下的成果进一步发展下去。

Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease.

This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of years. We grow old by deserting our ideals.

Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.

Whether 60 or 16, there is in every human being’s heart the lure of wonders, the unfailing appetite for what’s next and the joy of the game of living.

In the center of your heart and my heart, there is a wireless station; so long as it receives messages of beauty, hope, courage and power from man and from the infinite, so long as you are young.

When your aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you’ve grown old, even at 20; but as long as your aerials are up, to catch waves of optimism, there’s hope you may die young at 80.

there is only so much land on the earth, and so what we can do with it is limited. some people believe that human needs for farmland, housing and industry should come first, while others believe that some land should be set aside for endangered animals. i am of the opinion that we should reserve some land for the worlds animals for the following reasons.

first, mankinds need for land is constantly growing. if the demand is not checked in some way, humans will eventually develop all of the earths available land. at that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. second, humans are able to innovate and can use the land that they already possess in more efficient ways. animals are unable to do this. once their land is taken away from them they will die. third and last, endangered animals are an important part of the biodiversity of our planet. if they disappear, we cannot predict what the effect will be. therefore, we should treat such animals as a valuable resource to be protected.

to sum up, the worlds endangered animals are an important resource and we should protect them by setting aside some land for them. although mankinds need for land continues to grow, people are intelligent and inventive enough to put the land they have to better use. in this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

全文共 5272 字

The dog is one of the most popular pets in the world. It ordinarily remains loyal to a considerate master, and because of this the dog has been called mans best friend. Class distinctions between people have no part in a dogs life. It can be a faithful companion to either rich or poor.

Dogs have been domesticated for most of human history and have thus endeared themselves to many over the years. Stories have been told about brave dogs that served admirably in war or that risked their lives to save persons in danger. When Pompeii--the Roman community destroyed by Mount Vesuvius in AD 79--was finally excavated, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Perhaps few of the millions of dogs in the world may be so heroic, but they are still a source of genuine delight to their owners.

A dog fits easily into family life. It thrives on praise and affection. When a master tells a dog that it is good, the animal happily wags its tail. But when a master scolds a dog, it skulks away with a sheepish look and with its tail tucked between its legs.

People in the city as well as those in other areas can enjoy a dog. Medium-size or small dogs are best suited for the confines of the city. Large dogs need considerable exercise over a large area.

Dogs are not always well thought of, however. In recent years dogs in the city have been in the center of controversy. Some people have criticized dog owners for allowing their pets to soil sidewalks and lawns, although in some cities laws oblige owners to walk their dogs along street curbs. In turn, dog owners have argued that the animals serve as protection against vandals and burglars and thus protect their detractors as well as their owners.

When a person decides to own a dog, he should be prepared to care for it properly. For a dog to stay healthy it must be correctly fed and adequately groomed, and its medical needs must be met. For a dog to be well-mannered it must be properly trained. It should never be ill-treated or mishandled. Otherwise, it will bite in its own defense.

The wild ancestors of all dogs were hunters. Wolves and other wild relatives of the dog still hunt in packs for their food. Dogs have retained the urge to be with the pack. This is why they do not like to be left alone for long. Some breeds of dogs still retain the hunting instinct.

Dogs exist in a wide range of sizes, colors, and temperaments. Some, such as the Doberman pinscher and the German shepherd, serve as alert and aggressive watchdogs. Others, such as the beagle and the cocker spaniel, are playful family pets, even though they were bred for hunting. Still others, such as the collie and the Welsh corgi, can herd farm or range animals. Each of the dogs just mentioned is a purebred. A mongrel dog, however--one with many breeds in its background--can just as easily fit into family life.

Dogs have been with humans since prehistoric times. Over the years they have performed various services. They have pulled sleds over snowy tracts. They have delivered messages, herded sheep and cattle, and even rescued persons trapped in the snow. Dogs have served as a source of food, too. The ancient Romans are said to have prized certain kinds of dog stew. The Aztecs of ancient Mexico raised tiny dogs, thought to be the forebears of the chihuahua, to feed the large carnivores in the private zoos of the Aztec rulers. In the past dogs have even been worshiped as gods. Recently, they have been used in drug research, medical experimentation, and space science. Soviet scientists launched dogs into space to test the ability of mammals to survive the rigors of space travel before people were sent up.

Dogs are trained as guard dogs in peacetime by the United States Army and other military services. Because of their keen sense of smell, dogs are used by police at times to track down escaped prisoners. Law enforcement agencies also rely on the dogs acute sense of smell to uncover illegal drugs. And specially trained dogs serve as the "eyes" of the blind, guiding the steps of their sightless masters around obstacles and hazards.

狗是世界上最受欢迎的宠物之一。它通常仍然忠于一个体贴的主人,因为这个狗被称为人类最好的朋友。人们之间的阶级差别没有生活在狗的一部分。它可以是一个忠实的伴侣,无论是富人还是穷人。

狗驯化在人类历史的大多数时期,因此球员很多。故事被告知关于勇敢的狗,令人钦佩的战争或冒着生命危险拯救的人处于危险之中。当庞培——罗马社区在公元79年被维苏威火山——终于被挖掘,搜索者发现一只狗躺在一个孩子的证据,显然试图保护这个年轻人。也许一些世界上数以百万计的狗可能是英雄,但他们仍然是一个真正的喜悦主人的来源。

一只狗容易符合家庭生活。在赞美和感情。当大师告诉一只狗,它是好的,动物快乐地摇尾巴。但当主人骂狗,它潜伏了一个羞怯的外观和它的两腿之间夹着尾巴。

城市的人们以及那些在其他领域可以享受一只狗。中型或小型狗是最适合城市的范围。大型犬在大面积需要相当大的锻炼。

然而,狗并不总是值得思考的。近年来狗在城市里一直在争论的中心。有些人批评狗主人允许宠物土壤人行道和草坪,尽管在一些城市的法律迫使业主限制他们的狗沿着街道散步。反过来,狗主人认为,动物作为防范破坏者和窃贼,从而保护他们的批评者以及它们的主人。

当一个人决定自己的一条狗,他应该准备妥善照顾它。狗保持健康必须正确美联储和充分培养及其医疗需求必须得到满足。狗必须得到适当的训练表现得彬彬有礼。它不应该虐待或处理不当。否则,它会咬自己的防御。

所有的狗都是猎人的野生祖先。狼和其他的野生亲缘狗仍然集体觅食的食物。狗有保留的冲动与包。这就是为什么他们不喜欢独处太久。一些品种的狗仍然保留了狩猎的本能。

狗存在大范围的大小,颜色,和性情。一些,比如杜宾犬,德国牧羊犬,作为预警和积极的监督者。其他的,如小猎犬和可卡犬,好玩的家庭宠物,尽管他们的狩猎。还有一些,比如牧羊犬和威尔士科基犬,可以群农场或范围的动物。每个狗刚才提到的一个纯种。一条杂种狗,然而——有许多品种的背景——可以很容易适应家庭生活。

狗自史前时代以来一直与人类。这些年来,他们已经在执行各种服务。他们已经把雪橇在雪大片。他们传递的消息,赶羊和牛,甚至救出被困在雪地里的人。狗也有担任过的食物来源。古罗马人据说炖珍贵的某些种类的狗。古代墨西哥的阿兹特克提出了很小的狗,认为是吉娃娃的祖先,给阿兹特克的私人动物园大型食肉动物的统治者。在过去的狗甚至被崇拜为神。最近,他们被用于药物研究、医疗实验,和空间科学。苏联科学家发射了狗测试能力的哺乳动物生存的艰辛太空旅行之前人打发了。

狗是训练有素的警犬在和平时期的美国军队和其他军事服务。因为他们的敏锐的嗅觉,狗被警察有时用来追踪逃跑的囚犯。执法机构也依靠狗的敏锐的嗅觉发现非法毒品。和受过专门训练的狗充当盲人的“眼睛”,指导的步骤失明的主人在障碍和危害。

动物是人类最好的朋友,可是在现在的省会,残杀小动物的事件层出不穷,每当那个时候我都感到莫名的心疼,小动物也是一条小生命啊,为什么人类就忍心伤害它们呢,让我们呼吁全社会,保护动物,别再伤害它们了。

在那一天的阴暗的傍晚,我听着英语单词,捧着录音机走在回家的路上,看到了一幕让我悲愤的动物屠杀 ——一个人拎着一只吊着绳子的小狗,这可怜的小家伙被勒得口吐白沫,只见另一个人拿着榔头从一家饭店出来了。我赶紧转过街角想逃走,可是两条腿却不由自主地停了下来,躲在转角偷偷的向那望去。只见他们有说有笑,而那小家伙的眼神却是那么的绝望。突然那个人举起榔头使劲的朝它砸去。“呯”一股鲜血喷涌而出,那小家伙的脑袋顷刻间血肉模糊。鲜血不但染红了绳子,血腥味也在周围不断的蔓延······简直是惨不忍睹。我"逃亡"了,脑海里却一直闪烁那幅“血腥画”。一路上,我不断地追问自己:这是我看到的吗?这就是我眼中和谐的世界吗?

“人类,不是世界······的主宰······”我断断续 续的联想着,那个的血淋淋画面又出现了,同时那束奇怪的力量又直冲心头,又在热血里沸腾起来,好像一个哭泣的声音传过来:“呜呜呜呜······救救我们,救救我们,不要再伤害我们,不要在破坏地球了啊·······”我禁不住泪流满面。

是的,我们只有一个地球,而人类却践踏生灵。就算植物不会说话,那砍伐的树木中也会有第一滴泪,一滴代表绿色家族的泪。而那些可爱的小动物,等待它们的也是灭绝。我心中的力量平息了,心却下沉下沉,再下沉。“天灾,人类,主宰,残害,灭绝······”不断在我心头缠绕,“血腥画”将永远烙印在我的脑海,永不磨灭。

篇14:写濒临危机动物的英语作文北极熊

全文共 3755 字

+ 加入清单

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。

星期五下午放学后,我一回到家,打开门,就看见妈妈正在宰鸭。她脚下踏着鸭掌,手左捏着鸭头,右手正在挥刀杀生。我刚想阻止,怎料妈妈手起刀落,“啪”的一声,整个鸭儿摊在了地上,血从它的脖子上涌出来。

我走上前去,厉声质问妈妈:“你为什么要宰我的鸭儿。你不觉得这样很残忍吗?它是我的好伙伴,你却这样伤了它。书上不是说动物是人类的好朋友,我们要保护动物吗?”爸爸说:“区区一个鸭子,有什么好哭。”我再也不想跟他们辩了,于是直冲入房,捂住被子,号啕大哭起来。

吃完饭,我打开电视,在转到宠物频道时,我看到有一个人养了一只鸽子。有一天,那鸽子在树上被卡住了,飞不下来。于是,主人就不顾危险爬到树上去,将鸽子救了下来。但是却把他困在了树上,直到有人打了求助电话,他才平安地下来。

是呀,为了一只动物,那个养鸽人却能不顾生命危险去救助,多么令人感动呀!我们人类与动物就应这样和睦相处,好好保护我们地球的生态环境。不过,我听老师说,对圈养来改善生活的家禽、家畜,我们是可以区别地分开来对待的。

爱护弱小,是我们中华民族的传统美德。我想,用在这里,也是相通的。所以,我们一定要珍惜动物的生命,尽量不要伤害他们。

记得是去年的暑假,我和爸爸一起去鹅湖边散步,走了一段路,我就一个劲的喊口渴,于是,爸爸就在路边的小店给我买了根冰棍。我边吃边走,一会儿就吃完了,随手把冰棍棒往鹅湖里一扔。爸爸看见了,马上提醒我说;“可可,不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾,这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说:“知道了,我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说:“地球也是我们的家,我们应该保护它,爱护它,让天更蓝,水更清,草更绿。”我调皮的说:“噢,那就是大家一直说的,城市是我家,环境清洁靠大家。我明白了。”让从那以后,我再也不乱扔垃圾了。
