+ 加入清单I am a student in Huaxing Middle School. Do you know the plastic bags? Do you often use the plastic bags? I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose(分解) in a short time. The plastic bags will make our world worse. I agree with the rule, which people can’t get the free plastic bags in the shops, supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.
So I hope all the students in our class stop to use the plastic bags, and use our own cloth bags. I hope we can take care of our environment.
Let’s make our world more and more beautiful.

+ 加入清单亲爱的人类:
你们好!
不知你们是否看到过这样一副画面:广阔的蓝天,飘着朵朵白云;郁郁葱葱的山林中,一只只活泼可爱的小动物欢快地跳跃着、奔跑着。这是一副多么美好的画面。然而,现在这样的画面少得可怜,更别说能亲身与小动物们接触了。这是为什么?是因为人类对大自然的破坏——大肆砍伐树木,盲目地猎杀动物。
无知的人类呀,同样是生命,只不过一个是主宰者,一个是动物,却有如此大的区别。难道已丰衣足食的我们,非要忍心让他们无家可归?同样是生命,难道就不能与他们和谐共处?我难以想象,再这么下去,只剩下了孤独的人类地球会变成怎样?世界会变成怎样?在一片荒凉的大地上没有一丝植物的踪迹,昔日的小精灵也不知去向,大地一副死气沉沉的样子。风沙来了,没有办法;寂寞难熬,也没有人让你吐诉心声的。动物也是有感情,也是有心声的,假如换作是你,看到家园毁灭,伙伴去世,还会无动于衷吗?除非你是用铁做的心。但是,动物们只有默默无声地忍受着,忍受着命运如此不公的安排,没有一丝怨言,任凭生命中的每一样宝贵的东西消失,却毫无办法。人类啊人类,难道你们还没有觉悟吧?
“退一步海阔天空”,让我们从现在开始,从身边开始,从一草一木开始,为动物们,也为自己创造一个美好的家园!相信在不久的将来,小动物,小精灵,将成为我们生活中的不可或缺的乐趣,我们互相倾诉心声的好朋友。
努力吧,每一位有血有肉的中国人!

Animals Need Protecting
Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States aloneare considered in danger.
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. 保护动物的英语作文二:
It was a fine day today and the sun was bright. I visited Beijing Zoo with my classmate, He Song. The animals were so interesting that all the people loved them. When a bear asked for some food by waving its ann, a visitor threw something to it. At once I went up to him and said without thinking,Dont do that. Its bad for it. If you really love them, take good care of them. His face turned red and answered he wouldnt do that again.
今天是个风和日丽的好天,我和同学贺松去了北京动物园。动物们是那么可爱,大家都非常喜欢它们。一只熊挥动着胳膊向人们要吃的,一个游客就投进去了什么东西。我想都没想就走过去说:“不要那样做。你的做法对它们没好处。如果真的喜欢它们,就应该爱护它们。”他的脸红了,并且回答说他不会再那么做了。 保护动物的英语作文三:
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.
很多动物频临灭绝的危险。图表显示,我们可以看到动物物种数量下降的速度越来越快,而且这种趋势将会持续下去。从1980年到2010年,至少有100万动物物种已经消失。更糟糕的是,越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻,这是一个事实,一个残酷的事实。不幸的是,将来我们可能看不到这些动物了。
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.
从第二幅图我们可以找到一些原因。为什么动物物种的数量一年年的减少呢?显然,动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服,而且这些衣服都是高价出售。因此,一些贪婪的人就开始大量屠杀动物。这种不负责任的行为不仅打破了自然的平衡,而且使人类居住环境陷入危险。
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.
在我看来,我们必须要做些什么来阻止这种违法行为。我相信“没有买,就没有杀”。首先,我们必须制定有关法律来保护这些处于危险中的动物。其次,我们必须采取一些措施有效的保护动物。动物是人类的朋友,也是我们环境的一部分。再次,我们应该提高人们保护动物和环境的意识。这样一来,我们就可以建立一个和谐的社会,确保其可持续发展。 保护动物的英语作文四:

当它被人类捉起来的时候,他是多么希望有那麽一个人可以伸出援手来帮助他,解开他身上的铁锁,让他重新飞回天空。
可是谁会这样做呢?谁会不想吃美味的烤鸟啊,可是我们儿童不会,因为一个小生命在你手中,难道你会忍心看着它被别人煮来吃吗?
我想世界的每一个动物都想拥有自由,不会想眼睁睁的看着,自己被别人吃掉,所以它们飞向自己向往的地方。
我看到鸟儿们都在欢笑,他们喜欢在这片天空下飞翔,无论经过多少的风雨,他们也不害怕,因为天空是他们的飞翔的翅膀,他们带着希望,与其他的鸟儿,一起飞过一座座城市,看到了世界的美好,感受了飞翔的美丽,和那些经历过的酸甜苦辣,风风雨雨。他们飞了3100英里。你说在那段时间里,他们有过被别人爱护,也有过被别人本想捉起来的人。
啊!看,人们正在保护大自然,原来他们在保护每一个动物,不让他们灭绝,不让人们都看不到它的影子,不让它成为历史。每个人都在环保,把自己的垃圾放进垃圾桶,每年植物节都来种树,给动物们更多的家,更多的空间。
人类与动物让它们团结不是更好吗?让他们成为人类的好朋友,知心朋友,在你烦恼时让动物给你增添快乐,有时你们去草地玩耍,不停的奔跑,把什麽都忘掉,只顾着奔跑。
我们的好朋友永远都是动物们,无论是多麽凶险的动物,它们也是我们的好朋友,我们不会忘记,你们是我们永远的好朋友,是我们永远的希望。

全文共 1795 字
+ 加入清单Recently, our efforts to protect wild animals was questioned by the public,
because the news is keep reporting that more and more wild animals was killed by
human beings, especially the very precious one. Innocent animals was dead for
their meat, fur and tooth, it was just used to fill up human beings desire. In
my point of view, the wild animals were protected effectively still has a long
way to go.
Firstly, people should try harder to make a better place for animals. The
land where the wild animals live was deprived by human being. For hundreds
years, people cut the trees to make land for their living and farming, wild
animals homeland was took, they have no choice but run away. What is more,
human beings break the food link in nature; wild animals can not find enough
food to keep alive. There is no doubt that the destruction of nature has become
a big problem to kill wild animal, for instance, a polar bear was starved to
death because of the greenhouse effect, the ice was melt away, the seadog and
fish that polar bear like to eat are far away from them. For those reasons,
people should protect the environment first if they want to protect wild animals
effectively.
Second, no buying, no killing. Some rich people like to wear fur coat, they
treat it as a status symbol, especially for rich woman, they think animal fur is
beautiful and warm, they will never consider that the fur they wear for years is
the skin that animal wear for their whole life, and they knew how bloody when
people took the fur from animal but they choose to ignore it. If people do not
buy the fur and tooth, lots of wild animals will be survived.
In sum, wild animals are our friends, we should give back and protect their
homeland, and stop buying their body part, or our future generations will see
them in zoo and museum.

Take plastic bags, people know that plastic bags can cause white pollution, also know countries of plastic limit, but people are still in use, the pollution of the environment around us and the examples. Such as most people know that improper waste battery recycling will pollute the environment, but many time we threw them right.

地球晚们人类赖以生存的家园,它就像母亲一样,为我们提供生存资源和条件,谁不想让自己的家园变得更美,然而现实情况是我们地球已经伤痕累累了。保护环境已刻不容缓了。
人们经常把保护环境挂在嘴边,可真正做起来却不往往有些困难。就拿塑料袋来说,人们都知道使用塑料袋会造成白色污染,也知道国家的限塑令的要求,可是人们还是在用,我们身边环境污染的例子还有很多。例如人们大都知道废旧电池回收不当会污染环境,但许多的时候我们却把它们随手一扔。另外,我们周围浪费资源的例子还有很多很多,使用一次性筷子,常常忘了关水龙头等,为此根据实际情况我提出以下建议。
一、加强环境保护知识的宣传,教育市民收听、收看关于保护环境的节目,阅读环保知识读物,讨论环境保护问题,与破坏环境的现象作斗争。
二、倡导市民节约纸张,节约粮食,节约有水,节约用电,节约燃料,共同节约我们有限资源。
三、把损坏的物品修理好再用,延长使用期,多使用循环用的物品,不用或少用一次性纸制品。
四、设置专门回收部让垃圾及时回收并合理利用。
五、引导市民购买有环境标志和绿色标志的物品,不吸烟,不随地吐痰,不使用会破坏臭氧层的物品。
六、保护野生动物,不采摘花朵,不砍伐树木。

Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.
We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are
still put into rivers.
We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycie them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

+ 加入清单It seems we are living in the conflict between modern and traditional cultures every day.Hearing the blaring of horns the moment you step out of your house,seeing the so called "pop" the moment you open your eyes,you cant help thinking,"Will the traditional culture be gradually lost?"
Many people believe so.They may put right in front of you all the evidences they can dig out.They may argue that people are rushing to restaurants instead of cooking at home,listening to pop music but not traditional,wearing in a way people couldnt imagine ten years ago.Modern people like the air of freedom,not to be restrained by traditions.They offer this long list,only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading and will be lost at last.
Though we are now living in a world in which undeclared aggression,war,hypocrisy,chicanery,anarchy are part of our daily life.Though this is a skeptical age,and our faith has weakened,our confidence in some aspects of the traditional culture should and would never be lost.
Wouldnt you agree that our traditional culture is always credited with modesty,politeness and respectfulness,which have always been treasured for more than five thousand years?Even in this modern world,people still admire those with good manners,those who are polite to others or respectful to old people.
Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?
So there may just be some changes in our lifestyle or our attitudes towards life,but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.
The traditional culture will never be lost,I believe.
篇15: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。

在我们日常生活中 ,生活环境是十分重要的.但在日常生活中人们在保护环境上并不十分重视.
为了能让我们的环境优美,不受到伤害.有许多老人来打扫大街,绿化草坪.他们每天早出完归,为了祖国的绿化环境不惜一切代价。但那些不爱护环境的人偏偏还要去破坏,我们一定要为不爱护环境的人做好思想工作,让他们早一日改掉恶习。
在我们上学的路上,也有许队多同学乱丢废弃物。比如说:有的同学把小吃袋扔在校门口外,还有的同学把叠好的纸飞机随意乱扔,甚至顺着墙扔进学校.他们的这些行为不但一次又一地影响着学校,还给每天早晨做值日的同学带来了很大麻烦。
在校会上,老师一次又一次叮嘱、说服,但有些同学并不听劝,而是继续破坏环境,缩短地球的寿命。
有一次,学校组织我们2—6年级同学到采俸公园的草坪上捡白色垃圾。在出发之前,我心里想,平常到采风公园玩的时候,觉得那里比较干净。今天去捡白色垃圾,应该很少,捡起来一定很轻松吧。
但当我走道那里,低头一看的时候,却把我惊呆了。地上有许多垃圾。废纸、烟头、塑料袋等。这些到处都是,一块绿色的草坪,在游人的破坏下成了一片环境污染地,这是多么严重的环境问题。
面对这块草坪,使我们愤怒不已,努力去消除那些垃圾。经过我们100分钟的劳动,草坪终于恢复到了最初的美丽,名花齐葩争芳斗艳。我们不禁感叹:原来地球也是很美的呀!

First said the toys, many children, and even some adults, every time to buy a pet, such as cats, dogs, goldfish... At home, like toys play a trick on them, teasing, I want to say: the animal is also a life! They also have dignity! Also, to keep small animals if oversight, sometimes will make them sick, and even death.
Besides, dishes, many adults like to eat wild animals, like frogs, snakes... So, many animals are extinct! And also have a lot of harm to human body!!!! It is said that in 2003 "SARS" is caused by this! My sincere cautions: "please dont eat wild animals again!"
Also, many people especially love to eat frogs, so there are a lot of people to make money, cruel killing frogs to the vegetable market to buy...

动物是人类的好朋友,我们应该爱护它们、保护他们,可有些人却把它们当成了玩具和盘中餐……
先说玩具吧,许多小朋友,甚至一些大人,每次买了宠物,像小猫、小狗、金鱼……养在家里,把他们像玩具一样捉弄、戏弄,我想说:动物也是一条生命!它们也是有尊严的!还有,养小动物如果一时疏忽,有时会把他们弄生病,甚至死亡!
再说盘中餐吧,许多大人喜欢吃野生动物,像青蛙、蛇……这样,使得许多动物都灭绝了!而且对人体也有很大的危害!据说2003年“非典”就是因为这样引起的!我诚恳的告诫大家:“请大家不要再吃野生动物了!”
还有,许多人特别爱吃青蛙,所以有许多人为了赚钱,残忍的杀害了青蛙拉到菜市场去买……请问那些杀害青蛙的人,你们在杀害青蛙的同时,有没有想过,青蛙是人类的好朋友,他们能帮农民伯伯捉害虫、保护庄稼呢?
动物是人类的朋友,请大家保护动物吧!保护动物,人人有责!
