+ 加入清单我们要保护小动物,特别是小鸡这类弱小的动物,因为小鸡早晨可以叫我们起床,可以生一个又一个圆圆的的鸡蛋,还可以提供鸡肉给我们吃。
We need to protect the small animal, especially this kind of small animal chicken, because chicken morning to wake us up, can have a round egg, can also provide for us to eat chicken.
有一次,我和妈妈上菜市场,听见一位老奶奶在喊:“卖鸡了,今天的鸡又肥又嫩!”妈妈说:“今天,我们买一只鸡回家,炖汤喝。”我说:“好吧。”可又想了想:如果我们吃了鸡,那么就吃不到鸡蛋了,就对妈妈说:“不行,吃了鸡就没有鸡蛋吃了。”“傻孩子,你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡,只见她拔下鸡脖子上的毛,拿刀用力地在鸡脖子上划了几下。血喷向了四周,鸡挣扎了几下就死了。“太残忍了,我不要吃鸡!”我向妈妈大声的抗议。“好吧,不买了,我们就去买点蔬菜吧。”也许妈妈也觉得残忍,就同意了。
One time, my mother and I heard the food market, an old woman shouted: "chicken, chicken fat and tender today!" Mother said: "today, we bought a chicken soup to drink at home." I said: "OK." But think again: if we eat chicken, so cant eat the egg, the mother said: "no, not eat chicken egg to eat." "Silly boy, what do you care ah!" Mother allowing no explanation to put me into the chicken. The old woman was a chicken, she pulled out the hair on the neck, a knife in the neck with a few strokes under. Blood sprayed around chicken, struggled and died. "So cruel, I dont eat chicken!" I asked my mother loudly protested. "Well, do not buy, we went to buy some vegetables." Maybe mom was cruel, also agreed.
假如我们的生活中没有了动物,世界就会变得很孤独。我们要保护动物,从自身做起:少吃肉类食品,少穿皮衣毛衣;看见别人欺负动物,要勇敢地站出来劝说他们。
If we live without the animal, the world will become very lonely. We must protect the animal, start from their own: eat less meat, less wear fur sweaters; see others bully animal, we should stand up to persuade them.
保护动物,人人有责!
Animal protection, everyones responsibility!

+ 加入清单中午,我去美术班学习。在回家的路上,我突然在一棵树旁看到了一滩血。当时我害怕极了,仔细一看,原来树旁有一只死刺猥,它的头被砍去了一半,被砍过的伤口已呈黑红色,刚才那滩血就是它的呀!我感觉好恶心,飞快地跑走了。
是谁那么残忍?是谁杀了那么可爱的小刺猬?是谁?是谁?是谁……
动物是人类的朋友,我们不应该去杀害它们。人类和动物形成了一个“生物链”,没有了动物,就会波及到人类的生存。那些捕杀动物得人们难道不感到害臊?难道不怕动物们灭绝?难道不怕人类也灭绝?
世界上濒临灭绝的动物已经有许多许多种了。比如:欧洲的熊、狼、野牛、海狸等;非洲的犀牛、非洲象、斑马、大猩猩等;大洋州的袋鼠、树袋熊、袋狼等;亚洲的象、老虎、雪豹、大熊猫、猩猩等;北美洲的野牛等;南美洲的猿猴、鹦鹉、美洲虎等等。
那么多的动物都濒临灭绝,那些捕杀动物的人们一点儿也不知道吗?光拿中国来说吧!中国由于人类对动物的捕杀和人口的增多,有10种珍贵动物将从中国这块土地上消失。这10种珍贵动物是:盘羊、黑长臂猿、亚洲象、华南虎、东北虎、野生双峰驼,还有冠?、黑颈鹤、扬子鳄和河豚。它们即将从中国这块土地上消失,谁听了不会心痛。
人类大肆开发自然,剥夺了野生动物的生存空间,同时又为了人类的享乐而任意猎杀,导致动物的种类逐渐减少。人们难道一点也不惭愧吗?人类也是动物的一种,所以必须猎杀其他动物作为食物。但是人类却也为了自身的享乐而猎杀动物。例如:用美丽的的豹皮做衣服;用象牙雕刻;用狮头装饰房间;甚至有人以狩猎作为休闲活动,大量杀害稀有的珍贵动物。人类这样为了自身享乐而滥杀动物的行为,确实是应该受到谴责的!
最后,我呼吁全世界的人民:“保护动物吧!不要再捕杀人类的朋友了。

+ 加入清单寒假里,爸爸、妈妈带着我来到了杭州动物园。那里我去过好多次,但这次并不像以前一样兴奋。以前看到奔跑的骏马,上窜下跳的猴子,以为它们过得很快活。那天,我却看到它们伤心和无奈的样子。在这酷暑里,马儿不知要为多少游客服务,它们疲惫地耷拉着脑袋。上窜下跳的猴子被训练员鞭打,很可怜的样子!
走着走着,我又看到很多小动物被关在笼子里,像小鸟、小兔、小狗都关在很小,很湿的地方,小鸟“叽叽喳喳”地叫着,好像在说:“我又不是犯人,干嘛把我关起来,生活在比监狱还差的地方,真是太不公平了!”小兔“吱吱”地叫,好像在说:“救救我,我不想生活在这样的地方!”小狗“汪汪”地叫,好像在说:“你们还说动物是人类的朋友,对待朋友是这样子的吗?”
我们来到了黑熊住的地方,很多游客都不停往里面扔东西,根本没有注意旁边的警告牌“勿扔食品!”管理员告诉他们不要这么做,他们不听劝告,继续往里扔东西。在报纸上曾经报告过一个大学生为了做实验竟然把硫酸泼在一只黑熊身上,使它痛苦地倒下了,身受重伤。为什么那位大哥哥会这样残忍?难道他没有想过这样黑熊会很痛苦吗?
人们常说:“动物是人类的朋友。”对待朋友是这样的吗?对待朋友要像对待自己一样,这样才公平。动物是人类朋友,我们就该保护动物,善待朋友。

青蛙小时候穿着黑黑的衣服,头圆圆的,叫蝌蚪,长大了以后就变成了现在这个样子。青蛙捉害虫的时候会把舌头伸的长长的,把害虫卷起来吃到肚子里,真了不起,青蛙一天至少能吃70条害虫,一年能吃到15000条,甚至比这还要多,青蛙还是游泳专家,它游得可快了。
但是,现在有很多人把它们抓来吃它们的肉,还把它们抓到市场去卖,这样的行为很不好,所以,我们应该劝他们停止伤害青蛙的行为。我们又应该怎么样劝呢?下面我就给你们讲讲吧!
我们可以说:“你们这样做很不好,如果你们把青蛙捉完了,那农民们的庄稼怎么办?那我们的粮食不就被害虫吃完了?可是,我们还要吃粮食,因为没有了青蛙,农民伯伯只能用农药来杀虫,那些农药被雨水冲刷流到河水里,不是又污染了水源吗?我们人类饮用这样的水身体还会健康吗?所以青蛙对我们非常重要,我们一定要保护它们。”

+ 加入清单Each of us has one, two, three, even four or five ideals. Remember Leo Tolstoy once said: ideal is the beacon. Without ideal, there is no secure direction; Without direction, there is no life.
Why do I want to be animal lovers? First: I particularly sympathetic to animals, such as some stray dogs, stray cats stray animals, Ill give them while mom and dad to leave some food to eat, they will initially with a grain of salt, (because they are often some selling dog meat, and the cat, temptation, then......) So I went far away, looking at them in a secluded place finished eating, I didnt leave. The second: I know about animals in particular, almost every day I see happy pets, there will be a little information about pets. Like our little teddy - cool, I can see the cool body movements to determine what it wants.
If we live for 20 years, 30 years, animal lovers really when me, I will be banned from kill the stray animals such as dogs, cats, explore the loch ness monster really is, a cure for hydrophobic drugs, the study and the most important thing is to protect the animals, prohibit cruelty to animals, to feed the animals... To protect the environment, only in this way can the animals survive, if we cant live without animals, such as cattle, help mankind to plow.
Although I have not yet when animal lovers, but I also calculate the half animal lovers, but I still call on everyone to protect animals, starts from oneself.
我们每个人都有一个、两个、三个,甚至四五个理想。记得托尔斯泰曾经说过:理想是指路明灯。没有理想就没有坚定的方向;没有方向就没有生活。
为什么我要当动物保护者呢?第一:我对动物特别有同情心,比如一些流浪狗、流浪猫之类的流浪动物,我会趁爸爸妈妈离开的时候给它们一些食物吃,一开始它们会半信半疑,(因为它们常常被一些卖狗肉,参猫肉的,引诱,然后就……)于是我就走的远远的,在一个隐蔽的地方看着它们吃完了,我才离开。第二:我对动物特别了解,我几乎每天都看快乐宠物,里面会有些关于宠物资料。比如我家的小泰迪——阿酷,我可以看阿酷的身体动作来判断它想要干什么。
如果再过上20年,30年,我真的当上动物保护者,我一定会禁止人们掠杀猫、狗之类的流浪动物,探索出尼斯湖水怪的真正面目,研究出治愈狂犬病的药物,还有最重要的事情就是要保护好动物,禁止虐杀动物,随便给动物喂食……要保护好环境,只有这样动物才能生存下来,如果没有动物我们也无法生存的,比如说牛,帮助人类耕田。
虽然我还没有当上动物保护者,但我也算半个动物保护者了,但是我还是要呼吁大家保护动物,从自己做起。
篇12:保护野生动物高一英语
全文共 1339 字
+ 加入清单Many animals are in danger of dying out. As is shown in the chart, we can
see the number of animal species decreases faster and faster and this trend will
continue. From 1980 to 2010, at least 1 million animal species have disappeared.
Worse still, more and more wild animals are in great danger. It is not a piece
of sensational news; it is a fact, a harsh reality. Unfortunately, we may not
see these animals in the near future.
From the second picture, we can find some reasons. Why is the number of
animal species declining year by year? Apparently animals have become victims of
fashion industry. Animal skin has been used to make fashionable clothes and
these clothes sell at a high price. So some greedy people begin to kill animals
in a large quantity. This irresponsible behavior not only breaks the balance of
nature but also endangers the living environment of human beings.
As far as I am concerned, something must be done to stop this illegal
action. We believe "no buying, no killing". First, we must make concerning laws
to protect these animals in danger. Second, we must take some measures to
protect animals effectively. Animals are our friends and part of our
environment. Third, we should raise peoples awareness to protect animals and
our environment. In this way, we can build a harmonious society and ensure a
sustainable development.
篇13: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。

Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.
In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!
We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.
地球母亲就像是生命的摇篮,人类就像是地球的骄子。她,给予了我们生活所需要的一切离开她,我们就一无所获。美好的生存环境是我们赖以生活的基础,可是现在,我们保护环境的意识却越来越淡薄了。虽然,大家都知道保护环境,但却不自觉的掠夺地球的财产,破坏原本美丽的环境;其实,在生活中,只要留心,处处都能环保。
在我们周围的那些餐馆中随处可以看到,老板为了达到“卫生”的标准,而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的,一棵棵青翠的树木随着巨响而轰然倒下,一只只鸟儿被迫离开,一群又一群可爱的动物无家可归,可他们却当作没有看到,原本自然的生态环境就这样被他们破坏。不仅森林没有了,而动物也是不放过。最近,一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去,他们看着一只只可爱的小猴子无辜的死去,却还是无动于衷,这是多么令人发指的事呀!
我们身为地球的主人,如果不珍惜现在的一切,那这美好的环境一定会早早的离开我们。到时候,我们会面临灾难,地球也会伤痕累累,而受到伤害;所以我们应该做到主人应该做的事,好好的保护我们生存的环境,不要蓄意的去破坏,要记住:保护坏境,就是保护将来的人类。

However, in the eyes of some people, but these animals is some lose your life, no life, no feelings. They are just delicious or money can buy the things on the table, the people in order to kill all kinds of animals and birds, fur clothing and food in order to the so-called "mouth" a lot of killing selling duck, full mountain bird nets, traps set, overrun by shocking animal remains, such as there are numerous unsubstantiated reports that have appeared. Dropped sharply in animal species, some animals have become extinct or endangered, too cruel. Dont know what those people long is the heart of stone, if left unchecked, we can no longer hear birds schools of thought contend, and cant see the fish live the bottom of the sea, many animals will become "according to historical records". The world will no longer be rich and colorful, the world will only greedy human lonely and sad. This is the tragedy of the entire human race.
Have a word said good, protect animals is to love ourselves, any kind of animal in nature are one part of the food chain, a ring is indispensable, the lack of any one ring will upset the balance of nature, to suffer or ourselves, many animals are friends of human beings, human beings are not often divides into the animal beneficial insects and pests? If beneficial insects is destroyed, it is how a situation? If extinction beneficial insects pests also ceased to exist, the survival of the animal extinction is closely related to our life.
To protect animals, cherish life, is that we call, from the bottom of his heart. We should start from around things, care for small animals, care for the weak life, refuse to eat wild animals, refused to wear clothes made of animal skins, animal bones, accessories and supplies. Resolutely resist the behavior of animal cruelty, and animals together for us to build a harmonious coexistence of their homes.
你热爱动物吗?动物和人类一样都是我们这个美丽星球的拥有者,都有权利在这个星球上自由的生存,都有权利享有大自然赋予我们的一切,这是我们共同的家园。
然而在有些人眼中,这些动物不过是一些任人宰割、没有生命、没有感情的东西。它们不过是餐桌上的美味或能换取金钱的物品,人们为了皮衣和食品杀死各种飞禽走兽,为了所谓“口福”大量捕杀贩卖山珍野味,满山的捕鸟网,遍野的捕兽套,令人触目惊心的动物残骸,诸如此类的报道屡见不鲜,不绝于声。致使动物种类大幅减少,有些动物已经灭绝或濒于灭绝,太残忍了。不知道那些人长的是怎样的铁石心肠,如果任其发展下去,我们再也听不到百鸟争鸣,再看不到鱼翔海底,许多动物将成为“据史料记载”。这个世界将不再丰富多彩,这个世界将只剩下贪婪人类的孤独和凄凉。这是整个人类的悲哀。
有一句话说的好,保护动物就等于爱护我们自己,大自然中的任何一种动物都是食物链的一环,一环不可缺少,缺少任何一环都会打乱自然界的平衡,遭殃的还是我们自己,许多动物都是人类的朋友,人类自己不是经常把动物分为益虫和害虫吗?如果益虫都灭绝了,那会是怎样一种情况呢?如果害虫灭绝益虫也不复存在,动物的生存灭绝与我们的生活密切相关。
保护动物,珍惜生命,是我们从心底发出的呼唤。我们要从身边的小事做起,爱护小动物,爱护弱小生命,拒绝食用野生动物,拒绝穿戴使用兽皮、兽骨做的衣服,饰品和用品。坚决抵制残害动物的行为,为我们和动物共同营造一个和谐共存的家园。

青蛙有很多的技能,它可以预测天气,我国有很多农业谚语也反映了青蛙唱雨天气的关系,如“雨后蟾蜍叫,雨很快就到了”,当青蛙还在幼虫里时,它一天可以吃掉100多只幼虫。当它长成一只青蛙时,它能用机灵的舌头平均每天吃掉超过70种害虫。青蛙也可以预测收获,南宋诗人辛弃疾在香江月中叶写道,“稻花说一年好,听青蛙的声音。”

Lets take a look at the sky, the blue sky is gone, the white clouds are hidden, is it really gone? No, they are just "smoke" by the smoke from the factory.
These are water caused by it? Are our own human beings, if not felling of trees, garbage, a reasonable discharge of purified sewage, I believe our planet will be beautiful. Protect everyone from the earth, let us work together to protect the environment!

我们再来说说树木减少的问题吧!现在好多树木已经被我们砍伐叻,所以沙尘暴来了,洪水来了,大自然来报复我们了。我们都知道使用的一次性筷子都是用树木做的,如果我们每个人每天可以少用一双一次性筷子,一年下来就可以保留千万棵树木,看到这时,你还在放肆自己的行为吗?
我们再来看看那天空,蓝蓝的天不见了,白白的云也藏起来了,是真的没有了吗?不是的,它们只是被工厂排放的浓烟给“保护”起来了。
这些都是水造成的呢?都是我们人类自己,如果不乱砍伐树木、垃圾,合理排放净化过的污水,相信我们的地球就会很美。保护地球人人有责,让我们一起来保护环境吧!
