In the stream next to the road, there is a trash, in the trash next to, there are a lot of garbage: rotten apples, dead mice, Coke cans ... ...

Roadside, people coming and going, bustling, withering. They are talking and laughing, some people eat snacks, the garbage to the direction of the trash to throw; some people through here, smell the stench, clutching his nose hurriedly left; there are people Mamalielie, his face exposed Hated look. But no one is going to clean up the rubbish.

That day, Hasty and Showtime chest wearing a bright red scarf went to school. In the moment after the trash, they stopped, looked at the show, Showtime, said: "Hasty, we clean up the garbage!" Xinxin bent down, rolled up the sleeves, picked up the garbage into the Trash, they are not too dirty, even dead rats, dead cockroaches have not let go.

After the garbage, the winter and winter from the bag out of the pen and paper, touched the back of the head, waved "brush" to write: "civilization - only one step!" And then paste the slogan to the trash Warned passers-by.

I have heard such a story -

In a Korean home, there is a handy paper was blown away by the wind. He chased him all fifteen minutes on the street and threw it into the trash. The reason is not because of their own to bring pollution to the earth.

The earth gives the essence of the material, and in the end, it is from the people that the rebate is rubbish.

Treat the earth is to treat yourself. Save the earth is to save the future. So we want to start from today, from their own to protect our Mother Earth.

Protect the environment by everyone!

在川流不息的马路旁边,有一个垃圾桶,在这个垃圾桶的旁边,有很多垃圾:烂苹果、死老鼠、可乐罐......

路边,人来人往,熙熙攘攘,擦肩接踵。他们有说有笑,有的人吃完了零食,把垃圾往垃圾桶的方向丢去;有的人经过这里,闻到恶臭,捂着鼻子匆匆离去;还有的人一边骂骂咧咧,脸上露出了讨厌的神情。但是就是没有人去清理垃圾。

那天,冬冬和欣欣胸前戴着鲜艳的红领巾上学去了。在经过这垃圾桶的瞬间,他们停下了脚步,看着看着,欣欣说:“冬冬,我们把垃圾清理干净吧!”欣欣弯下腰,卷起衣袖,把捡起了垃圾放进垃圾桶,它们不嫌脏,连死老鼠,死蟑螂也没有放过。

收拾后垃圾后,冬冬从书包里拿出纸笔,摸了摸后脑勺,挥笔“刷刷”地写到:“文明——只差一步!”然后把这标语贴到垃圾桶上,以告诫路人。

我也听过这样一个故事:

在一个韩国人的家里,有一张可要可无的稿纸被风吹飞了。他整整在街上追了十五分钟才追到,然后把它扔进垃圾桶里。原因是不想因为自己给大地带来污染。

大地给予所有人是物质的精华,而最后,它从人们那里得到的回赠都是垃圾。

善待地球就是善待自己。拯救地球就是拯救未来。所以我们要从今天做起,从自己做起,保护我们的大地母亲。

保护环境靠大家!

Environmental protection is not a new question for us, our government has put forward clear governance objectives. As every ordinary people in real life, although not may be directly engaged in environmental protection work, but we can starts from the minor matter, starts from me.

When see the bathroom faucet is dripping, close is able to raise your hand? When the battery after use can be classified collection processing and not carelessly throw away? Whether consciously or the use of ultra-thin plastic bags when shopping? Them are very small, but it reflects how much we have environmental protection consciousness.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 big tree. Recycling waste 20 boxes can create a beautiful pen container. Recycling one glass bottle to save energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

环境保护对我们来说并不是一个新问题,我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人,虽然不可能都直接从事环保工作,但我们完全可以从小事做起,从我做起。

当看到洗手间的水龙头在滴水时,是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?一件件小事虽然都很不起眼,但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸,可以挽救17棵大树。回收20个废餐盒可以造出一个漂亮的笔筒。回收一个玻璃瓶节省的能量,可使灯泡亮4个小时。回收1个铝罐就等于节约了半个铝罐的石油。所以我们应将垃圾分类安放,由有关部门回收后再生产再利用!

只要我们从自己做起,从小事做起,大家共同努力,持之以恒,就一定能为社会、也为自己留下一片碧水蓝天,我希望人人都能自觉保护环境,让我们的生活环境更加美好。

动物是人类的好朋友,但是人类却不懂得去爱护它们、保护它们。

生活在长白山上的东北虎10年前还有10只,现在却不足8只,因为长白山上环境被恶化,所以使东北虎面临灭绝;只生活在长江中下游的白鳍豚10年前还有20头,但2008年科学工作者在长江中下游勘察了一个星期却没有发现一头白鳍豚,如果这一项工作被证实的话,那么白鳍豚早在2008年就已经灭绝了,因为长江中下游的水环境被严重破坏,所以使白鳍豚面临灭绝;我国的国宝大熊猫现在已经不足20只了,大熊猫已经有几千年的历史,被称为‘活化石’!它具有很大的科学考察性。因为我国的大面积竹林被破坏,所以使大熊猫面临灭绝;可爱的羚羊,野生动物王国的跳跃健将和奔跑的佼佼者,却因为过度放牧,所以使羚羊只能嚼着干瘦的‘地衣’和面临灭;还有不会飞的水栖鸟—企鹅……难道我们就忍心看着这些可爱的动物们面临灭绝吗?

现在的人们为了钱可以不顾一切,‘钱乃身外之物’钱没有了可以再挣。但是动物灭绝了就再也没有了!为了我们人类请保护它们,为了我们的家园请保护它们,为了自然生态的平衡请保护它们!虽然我不是诗人,我不会用优美的语句去恳请人们保护动物们,但是我会用发自心腹的真心话去恳请人们去保护动物!我们已经经历过一次恐龙灭绝了,恐龙的灭绝使我国的研究受到了一定的阻碍。难道我们人类只有经历过所以动物的灭绝才会醒悟吗?

如果动物灭绝了,那么,接下来灭绝的就是人类!保护动物。

作文【一】

One day Sun Wukong together with his master and brothers was walking across a river. Suddenly his master fell off the horse by the bad smell of river water. They found the water so dirty that they could hardly breathe.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed. If the river water all over the country is polluted like this, no living things will exist in the water. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

作文【二】

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.

作文【三】

Dear editor,

Environmental problems are becoming more and more serious all over the world. _________________________________________________________

Yours truly

Li Hua

Dear editor,

Environmental problems are becoming more and more serious all over the world.

With the development of industry and agriculture, cars make great noises and give off poisonous gas. Because of population expansion and overdevelopment, resources has become less and less. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.

We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.

Yours truly

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿,而且因为缺水而干渴。对你来说这可能似乎奇怪:因为我们的地球表面75%由水覆盖着。但是,这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下,和其他来源的淡水供人们饮用、使用。即使如此,这3%的水源我们也不能够完全使用,因为有些淡水是以冰山或冰河的形式存在。更糟糕的是,一些水源已遭受了污染。

然而,尽管按现状看来,这些少量的淡水即使时常转化成雨水的形式,对我们来说,也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91,000升水,你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行,但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言,与空间站不相上下。

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友,人们应该善待它们,但现在,中国和世界上的许多人为赚钱而捕杀动物。众所周知,中国有许多珍稀动物,如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋,或是为了食用它们的肉。

结果大量的珍稀动物死亡了,真可惜呀!

目前,我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们:也捐款来支持保护动物的活动,如,有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物,因为自然就像一个大家庭,人类和动物必须和平共处:我们必须保持生态平稳。

如果人类能这么做,这个世界就会越来越好。

环境保护雅思英语作文怎么写呢?相信很多同学想知道。以下是小编为大家整理分享的环境保护雅思英语作文,欢迎阅读参考。

环境保护雅思英语作文

You should spend about 40 minutes on this task.Write about the following topic:

The earth is being filled with waste material such as plastic bags and other rubbish. Is this really happening? What are some solutions to this problem?

Gives reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.

model answer:

Over the past few decades, the increasing amount of industrial wastes and household garbage has become a major problem in many countries. People have questioned what caused this problem and what can be done to improve the situation. In my opinion, two of the most critical causes of this waste material problem are the increased consumption and a shortage of space for landfill.

To begin with, modern lifestyle has contributed greatly to the increasing amount of waste and garbage we produce everyday. In other words, we have turned into a materialistic and mass-consumption society where we use more and throw away more than ever before. Moreover, countries are running out of space to store garbage and waste material. In fact, securing land for waste disposal raises controversies in many countries.

To solve this intractable problem, every citizen needs to participate in producing less garbage. For example, we can bring our own personal shopping bags instead of using plastic bags provided by stores and shops. Besides, the government can enforce stricter laws on companies to use biodegradable packaging or use recycled material. Indeed, this alone can eliminate much of the waste which is sent to at land fills. Companies can also contribute by developing new raw material which is recyclable and will ultimately lead to less garbage. One good example of this is that tire companies develop new tires for cars which are not made of rubber but of new biodegradable material.

As discussed above, individuals, business and the government can share the responsibility to reduce the amount of waste material and to save the earth. I hope that in the future our offspring will be better off with the well-preserved environment.

环境保护雅思英语作文

Environmental hazards are often too great for particular countries or individuals to tackle. We have arrived at a point in time where the only way to lessen environmental problems is at an international level.

Environmental problems have reached such proportions that people feel international organizations must be set up to intervene in world affairs to resolve these problems. Whether this will resolve the problem is very unlikely as international organizations are just an extension of human behavior. That is, if human conflicts cannot be resolved at home, then they are unlikely to be resolved at the international level. Nevertheless, international organizations do attract attention to the growing problem of aims of the international community to resolve the issue of environmental pollution and support their cause, I do not believe it is the best or only way to protect the environment; in fact, it is only a small part of what is needed in a global initiative.

All world problems, whether it is environmental pollution, war, energy insufficiency, or famine, arise from the abusive behavior of all individuals. Therefore, the solution to all these problems is the need for a collective consciousness. What is meant by this is that each individual must be aware of the impact he or she has on the world and their unique part to play in this world. After all, if one is happy with his life, he will surely not endeavor to harm the environment or anyone else. His behavior will be that of a responsible individual.

What is needed, therefore, is education. Education is the key to all problems and it starts from pregnancy all the way to adulthood and beyond. Furthermore, education means that children all over the world should be allowed to go to schools with good teachers and where teaching materials and methods can be adapted to each individual. Education means raising children to be responsible individuals.

This may sound like utopia, but it is not: if a country had important problems in its educational system, then it should realize that it is contributing to the worlds problems. These are perhaps long term solutions, but they are more realistic solutions than setting up yet another international organization.

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。

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天,大姨带我去大梅沙看大海,因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮,我觉得大海应该是这样的:碧蓝的海水,浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树,海边静静的躺着许多贝壳,海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空,天空上的一轮红日,海欧飞来飞去,这景象多美呀!多令人陶醉呀!我心情轻松愉快。

可当我才看见大海的一瞬间,我失望了,心情一下子变的沉重了。因为我眼前的大海是灰暗的,是浑浊的,是没有生气的,是没有自信的。有的只是自卑。我知道大海原来不是这样的,而是被人们污染成这样的。

现在,人类为了生活,大量砍伐树木,砍了又不栽,以前有多少热带雨林,现在是平地,以前多少树木,现在取而代之的是高楼大厦。工厂排放的废气,污染空气,又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水,让水里的小鱼,小虾都被毒死了,河面上浮着发臭的鱼的尸体和垃圾,这一切又是多么的可怕呀!

让我们去拥抱大自然吧!去保护大自然吧!让世界上的一切都变得美好。
