Every year on October 4th is the World Animal Day. It is proposed by the Italian monk St Francis in 12th century. He lives in the forests of Assisi Island for the long time, building a good relationship with the animals. So he asks people to express thanks to the animals on October 4th. He sets a good example for our human beings about how to deal with the relationship with animals. In order to memorize him and what he does, we make October, 4th to be World Animal Day. Nowadays, people from all over the world will hold various activities to celebrate on that day. The aim of this festival is to remind people to care for all animals and build a harmonious relationship with them.

每年的十月四日是世界动物日。它是由意大利修道士圣弗兰西斯在十二世纪提出的。他长期生活在阿西西岛上的森林中，与动物建立了良好的关系。所以他要求村民们在10月4日这天向动物表示感谢。他为如何正确处理与动物的关系树立了一个很好的榜样。后人为了纪念他和他所做的，我们把十月四号定为世界动物日。现在，在那一天来自世界各地的人会用各种活动来庆祝这一节日。这一节日的目的在于提醒人们关爱所有的动物，与他们建立和谐的关系。

A thought-provoking dialogue between the mother elephant and her own child appears in the first picture. Having growing his teeth, the young elephant is eager to share the exciting news with his mother. However, after repeating his words several times, there is still no response coming from the mother. Meanwhile, the attractive caption in the second photo reads: no trade, no kill.

The above pictures unveil a hazard posed to wildlife due to the expanding scale of world commercial hunting. At least two fundamental factors could contribute to this phenomenon. The industry of commercial hunting have undergone a booming expansion (along with the growing public awareness of the merits of wildlife, which makes/), making hunting unusually profitable. Worse still, lacking knowledge regarding the significance of ecological balance, some people take the gun to chase animals insatiably (and thus cause a severe threat to all life in the world). Apparently, this trend will surely in turn endanger humankind in the long run.

(On no account should we turn a blind eye to such things.//All these factors above make it crucial to take drastic measures to protect the wildlife.) Accordingly, governments all over the world are supposed to unite to work out effective measures against commercial hunting. Additionally, people should be educated from childhood to cultivate the awareness that we and the rare wild animals share the same precious planet. I do believe a harmonious relationship between the wildlife and human beings is awaiting us if we make every effort to promote wildlife protection both nationally and internationally.

有一天，我去集市，我听到爷爷喊：“!!青蛙出卖自己给自己卖青蛙青蛙跳”然后我听到几声凄惨的青蛙，我走过去，顺着声音，爷爷看见几个青蛙用绳子绑在一起，向外伸出前掌，试图蒙混过关。总是可以拉出的祖父，也充满了青蛙篮子。祖父的眼睛是很多很多的钱，而不是漫天飞舞的蚊子爪。我看着这一幕，听着惨叫声，我的心脏不禁咬紧。

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。”

我们学会了“狼和鹿，”一个教训，但人们为了保护鹿狩猎狼，鹿进入森林砍伐的罪魁祸首，鹿和凯巴伯森林消亡的过渡。本文告诉我们：所有的自然事物是紧密相连的，不能破坏生态平衡，否则后果将不堪设想。你爷爷卖青蛙想想看：如果你抓住了一只青蛙，它只会放手七十害虫，你想看到蚊子的天空图和蚊虫叮咬黑色和我们的蓝色?

人啊!醒醒快。 !别再让害虫猖獗我倡议：让我们与动物和平共处的人类最好的朋友的保护 - 青蛙吧!

You know, theres a lovely puppy in the aunts house. It has white hair all over the body, white as cotton candy; its eyes are black and white, like two precious stones; ears are semicircle, nose is black, tail is short. Its really beautiful!

One day, I went to the aunts home to play. As soon as I entered the door, I saw the dog barking in the doorway, as if welcoming me to his house. I saw it, smiled and said: "small naughty, do not worry, I will play with you immediately!"."

As I entered the room, I sat down on the sofa and wanted to rest for a while. But it licks me with its tongue. I cant stand this kind of "affectionate" reception, so I have to go out with him.

Outside, we played hide and seek. I hid in the middle of the back of the car, waiting for it to come to me. After a while, I saw him running nimbly towards this place. Suddenly, it came to me with a slam on the brakes, but it didnt realize my existence. So I decided to come and see what it was like.

It was the body of the hair, like a bath. It spat out its tongue against the sun. Yes, the weather is so hot today, just like the fire on the ground. But it also found me at this time. Ah! It become more lovely! Light shining white hair, looks very smooth. Its eyes were fixed on me, a smile on my face, as if to say, "look, boy, Ive found it."".

I really like this cute puppy!

Taking care of our school and

Taking care of our school and protecting our school environment! A clean and pleasant environment is very important, because it can make us healthy and happy.

It’s our duty to protect our school environment. We should clean the school every day. And we shouldn’t drop trash here and there. We should pick it up when we see trash on the ground.

We shouldn’t draw on the wall. If we all like our school the same as we like our homes, our school will be more beautiful. We will enjoy our study better. Let’s protect our school environment from now on, shall we?

Recently I found out that some bad things happened in our school.

At ordinary times is very neat and clean campus, has recently become some dirty, some corner or in the corridors, students can be seen the plastic bags used to hold things, eat some fruit peel, cabinet and throw away the packing bag of after loud snacks. Is each class in our school there is a certain region responsible for cleaning, clean, will arrange the students per class every day the rubbish is certainly in the classmate after cleaning the health, and others left, I think the quality of the students really is very low, I dont know to cherish other peoples work achievement, dont know how to protect the campus environment.

Students, not to be good, not to be, not to be evil small but to be, everybody join hands together, protect our campus environment together!

最近我发现我们的学校发生了一些不好的现象。

平时十分整洁干净的校园，最近却变的有些脏兮兮的，一些角落里或者是走廊里，都能看到同学们用来装事物的塑料袋，还有一些水果皮、碎纸屑和吃完小零食以后扔掉的包装袋。我们学校是每个班都有一定的卫生打扫的负责区域的，每天每班都会安排学生打扫，这些垃圾肯定都是在同学打扫完卫生之后，又有人丢下的，我觉得这些同学的素质真的很低，都不知道珍惜别人的劳动成果，不知道保护校园的环境。

同学们，不以善小而不为，不以恶小而为之，大家携起手来，共同保护我们的校园环境吧!

All things cannot be separated from water, and fish cannot leave water.The theme is: water, the root of all things.

It is true that the seven parts of the sea are right. We are from one of the creatures in the sea, and we have the same gills of fish when we are young...Everything shows that we are connected to the sea.

Maybe we were just a little fish, but now we are the greatest humans.

The sea is so kind and mysterious, what is it that we humans are, the most intelligent creatures at the top, what are our ancestors?Its a low-grade fish or an advanced dinosaur, and everything is a mystery.

Now the sea is being developed by us, the sea ranch, the Marine oil base is so amazing.The sea gave us life, and gave us so much energy, and we?Marine oil base causes large oil spill, resulting in Marine oil pollution!What are we doing with the indiscriminate killing of whales and the salivating of shark fins?Is the environmental protection or the destruction of the ecological balance?

If the sea could wash everyones heart like a shell, there would be no creatures in the world because of our indiscriminate killing.Is it a reward that the sea is our mother, and it has created the destruction of all that it has created?No, it isnt.What else can we do when black oil covers the ocean, and when black exhaust fills the sky?The sea belongs to nature, nature belongs to us?We belong to the sea, and the sea belong to us?

What are we doing here?To kill for personal gain?Destroy for yourself?No, no, no.I do not believe that we will destroy our oceans, and I do not believe that people will despair when the oceans disappear.Because everyone is selfish.

Is it humane that the oceans have created us and destroyed us?

Although were trying to protect the environment, its too late, unless time goes backwards, unless theres a miracle, unless its all over again.I believe we can get the ocean back to our youth, and we are the smartest intelligent creatures.

Everyone, for the sake of the bright future of the sea, also protect the sea for ourselves.thank you

我们今天的英语作文也许解决不了国家大事，却可以帮助我们增加对于环境保护的意识。下面是小编带来环境保护英语作文，希望对大家有帮助。

环境保护问题英语作文篇一

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

I saw a chemical factory pouring the waste water into the river.The river was very dirty.The fishes and animals died because of the pollution.It also polluted the flowers and grass near the river.

I think we should protect the environment.I think the government can do something useful to stop the pollution and protect the environment.

环境保护问题英语作文篇三

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

Recently, a large number of affairs about sexual assault were disclosed and reported by mass media. As far as I am concerned, people should get some enlightenment from these affairs, such as enhancing and strengthening education inSelf-protection awareness, especially for children and students.

最近，有很多关于的事件媒体揭露和报道。我认为人们应该从这些事件中得到一些启示，比如，提高和加强自我保护意识教育，特别是对于儿童和学生。

Children and students are hurt most in this kind of affairs. As a result, to enhance and strengthen their self-protection awareness is indispensable. In addition, to strengthen the awareness of defending danger is also important. If they can realize the potential danger from someone or something before it happens, they can make some preparations to avoid the danger and reduce the rate of being hurt.

因这类事件伤害最大的是儿童和学生。因此，提高和加强自我保护意识是必须的。此外，加强防范危险的意识也是很重要的。如果他们能在事情发生前意识到某人或某事的潜在危险，他们就可以做一些准备来以避免和减少受伤率。

Therefore, I advocate that parents should help their children develop self-protection awareness from birth, such as designing some situation for them to cope with. In addition, parents should teach their children to recognize the danger and how to avoid and reduce the danger from outside. Besides, children also need to develop an excellent ability of observation.

因此，我认为父母应该帮助他们的孩子从出生开始就培养自我保护意识，比如，设计一些情况来让他们应付。父母还应该教导孩子认识危险，如何避免和减少来自外界的危险。此外，孩子也需要培养优秀的观察能力。

In a word, to protect children needs both the effort of parents and children themselves.

总之，保护儿童需要家长和孩子他们自己的努力。

Dolphin is my favourite animal.

It is one of the most precious animals. Their bodies are very long, about one zhang. Dolphins live in the sea. They live on fish, shrimps and so on.

Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!

Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.

Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.

When I was very small, I could see many birds flying in the sky when I looked at the sky, but as I grow up and move to the city, I find less birds in the sky.

关于保护动物高中英语作文1：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 alone are 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 plant on the danger list. Slowly, the number of some animals in danger is growing.

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

关于保护动物高中英语作文3：How tu protect animals

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

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。

这只小乌龟非常可爱。大大的龟壳，小小的脑袋，还有有力的四肢。让我疑惑不解的是小乌龟不胆小，我用手碰它的头，它也不肯把头缩回去。小乌龟全身碧绿，只有肚子比较白。眼睛比较小，它的眼睛一只睁着，一只闭着，我想它可能是生病了。

有一次，我给小乌龟换水，我把小乌龟拿出来，它却想把头伸过来咬我的手，我想它可能饿了，便让妈妈切一块肉，我就让乌龟把肉叼住，可是它咬住了并不往里吞，我觉得小乌龟比较笨。

我很喜欢我的小乌龟，我希望能让小乌龟多活几天，但不幸的事情发生了。

一次我给它换水，发现它一动也不动，我好奇的把小乌龟放在深水里，我想它应该会吐一个气泡，结果它没有吐气泡，还是一动也不动，我想它已经死了。

我很伤心，因为跟它在一起很好，我本来想让它多活一会儿，结果它却在今天死了。

我想人们有工夫养它（动物），就要好好养它，就不要放弃它。阳台旁边的一群猫

去年，在夏天，我在阳台晒太阳，忽然，我看见阳台前的花园出现几只小猫在玩耍，还有一只大母猫在放哨，我想这只大猫就是它们的妈妈吧。我把这件事告诉了妈妈，妈妈说：“你要喜欢的话，可以天天给它吃的，让小猫们还有大猫信任你。“我向妈妈要了一点牛奶还有剩的鱼拿去喂它。我刚走过去，看见猫早就没了，我只好把奶还有鱼放在两个盘子里，放在它们能看见的地方。不一会儿，那几只小猫还有大猫都出来了，是大猫先看见食物的，首先，它叫了几声，好像在说：“有人类给咱们食物了，快来吃吧。“小猫们立刻跑到食物跟前狼吞虎咽的吃了起来。它们一定好几天没吃了。

就这样，它们每天都来玩，来吃饭，日复一日，它们变胖了，它们已经跟我们熟了。

一次我在花园玩，忘了关门了，回来的时候，我发现家里有四只猫，，两只是花的，一只是黑的。我想去给它们挠痒，但是它们都走了，只有两只猫留下来，一只大灰猫，一只小花猫。一个月以后，只有一只常到我们家串门。

我想，动物们需要自由，不要把它们关在某个地方，要爱护动物。
