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.Trees on the hills have been cut down,and waste water is being poured continuously into rivers.Furthermore,wherever we go today,we can find rubbish carelessly disposed.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 mans existence.

We must face the situation that exists and take actions to solve our environmental problems.For instance,new laws must be passed to place strict control over industrial pollution,the public must receive the education about the hazard of pollution and so on.We hope that all these measures will be effective and bring back a healthful environment.

The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and peoples living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great mount of carbon dioxide gases, which further intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.

Definitely, air pollution will exert a detrimental impact on many aspects of peoples life. For example, many diseases such as cough, skin problem and lang cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.

参考译文

此图生动地揭示了空气污染和空气质量下降的现象。到底是什么导致了这个现象?可能的理由罗列如下:首先,机动车的尾气排放是最主要的原因之一。随着经济的发展和人们生活水平的提高,越来越多的城市居民都拥有了自己的汽车,而更多地汽车势必带来大量的尾气排放。其次,城市里广泛使用的家用电器排放了大量的二氧化碳,这也进一步加剧了空气污染。最后,城市周边的很多的工厂,也每天向空气中排放大量的未经处理的有毒气体,这也导致了空气质量的下降。

If same, groundwater contamination, people will drink less than clean water, humans will get sick, poisoning, and it may even die. So, no one should be put on the possible environmental pollution of waste into the river.

Air is a guarantee to the survival of all living creatures. If the air is polluted, all creatures will live in the "gas", disease and all kinds of disasters will be the humanitys greatest enemy. Last, mankind will perish. Visible, clean air is how important!

Garbage can be seen everywhere in our daily life, the visible human bad habits - littering behavior is really too serious. Random pile up garbage can cause great harm to the environment, such as: air pollution in a breeding ground for germs, sexually transmitted diseases, and river and so on.

The pollution was terrible! To prevent the pollution, we must care for the environment, protect the earth, to stop all the pollution of the environment.

生活中,环境污染不断地影响着我们的生活。比如:被污染的空气、河流和垃圾污染等等,已经严重地破坏了我们的生活环境。

河流被污染了,水中的生物将无法生存,也不能用它浇灌庄稼,人类将吃不到新鲜的食物。同样,地下水如果被污染,人们将喝不到洁净的水,人类将会生病、中毒,甚至可能会死亡。所以,任何人都不应该往河里投放有可能污染环境的废弃物。

空气是所有生物赖以生存的保证。如果空气被污染了,所有生物将会生活在“毒气室”一样的环境里,疾病和各种灾难将会是人类最大的敌人。日久天长,人类就会灭亡。可见,洁净的空气是多么重要啊!

垃圾在生活中随处可见,可见人类的坏习惯——乱丢垃圾的行为实在太严重了。随意堆放的垃圾会对环境造成很大的危害,例如:滋生病菌、传播疾病、污染空气以及河流等等。

这些污染真是可怕呀!要预防这些污染,我们一定要爱护环境,保护地球,制止一切污染环境的行为。

At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

In the discharge of smoke in the factory, we dont know the smoke is atmospheric pollution? Scientists have found that there are at least 100 species of air pollutants produced great harm to the environment, directly affect peoples health.

在21世纪的今天,人类的科学经济发展已经达到了很高的水平。然而我想问:你们有没有意识到人类的活动对环境会造成怎样的影响呢?

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失,使许多地区成为沙漠。人类的活动范围在不断减少,这不可怕吗?

人类除了破坏森林之外,难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性,目前世界上60%的地区面临供水不足,已有20%的人口难以得到清洁水,51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的,现在的工厂及我们生活中的污水,没有通过处理就排出去。这不是最好的证明吗?据研究,每排放1立方米污水,就污染14立方米天然水。想一想,这是多么可怕的数字?

在工厂排出的浓烟里,我们不知道浓烟是污染大气的吗?科学家发现,至少有100种大气污染物对环境产生极大危害,直接影响人们的健康。

Environmental problems are as big as not for individual country or individual people to address。 In other word, we have reached the stage that environmental problems be solved for international view。 To what extent do you agree or disagree?

In recent years, many nations have bee more aware of the environmental issues each nation faces, such as air and water pollution。 The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc。, the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

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。

2030年的一个清晨,机器保姆叫醒了我,我懒懒地从被窝里爬了出来,穿上衣服,机器人又把我请到洗手间,正当我准备刷牙洗脸时,一滴脏水滴了下来,正好滴在我的身上。

我生气了,抓起一根木棍“咚咚咚!”上面的裂口更大了,“哗!”的一声,一大股脏水泼洒下来,淋了我一身,我仿佛洗了一个凉水澡,浑身湿淋淋的。“啊!我的衣服!还有我用五百元买的裤子呀!”我又生气又伤心的大喊着。机器人看着我这狼狈不堪的样子说:“主人,您知道为什么水会这么脏吗?那是因为你们乱丢垃圾,水都被你们污染了,所以才会那么脏的”。

我恍然大悟,跑到窗户边一看,啊!太可怕了;外面飞沙走石,河水从清澈见底变成了浑浊无比;水里的鱼都死了,只有一些生命力顽强的水草还勉强活着,但很快就奄奄一息了。田野上到处都是垃圾,枯草,枯树。一副死气沉沉的画面摆在眼前。

Important to save water

Water is a kind of liquid. It has no taste or smell. It is transparent, too. Water is useful and is important to us. Why? For example, we use water to water the plants. We use water to wash our face or to have a bath. We drink water or we will die…Water is also very important for China. There are 2.8 hundred millions of steres of water in China, but everyone can only use 2300 steres. It is only twenty–five per sent in the world.

Not too long ago, there was a man called Jacques Cousteau. He loved the beautiful colors, and the beautiful fish in the sea. However, when he returned some years later, the colorful coral reefs were dead and grey because the factory near the sea poured waste water into the sea. Jacques Cousteau decided to tell people how important it was to save the environment under the sea. He started the“ Cousteau Society ” to help protect life in the sea. Now there are over 30000 members all over the world. Since water covers most of the earth, Cousteau knew that we should keep the sea clean. We should not litter the sea, and should clean up the dirty parts. As water is very important to our environment, he encouraged everyone to take part in protecting our lakes, rivers, sea and ocean.

There are still a few people who are not protecting the water now in the world. For example, some factories pour waste things into the rivers, lakes or into the sea near by. The water there has become very dirty and we can’t use them at all. Although there are seventy–five per sent of water in the world, we can only use fresh water, that there is only a little. So we should use little water when we need to use it. For example, I do not use too much water when I am washing my face or having a bath… It is important for us to keep the water clean. You may ask yourself, have I ever poured or thrown dirty things into the water? If your answer is “No”, that means you have already helped to protect the environment. It is our duty to protect the environment. You may ask yourself again, have I ever helped to clean up the water? If your answer is “Yes”, that means that you have already done something useful to improve the water. If we use up all the water, it is difficult for us to get it from anywhere, including the universe. It is terrible to think that people are too thirsty to live! I believe, that if everyone helps to protect the water, the water must be protected. You do not want to “kill” your son or your grandson, do you? So now let us to protect the water! Please don’t let the last drop of water on the earth is we human’s tear!

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!

Today I saw an article called "everybody comes to the bend". The message is that the students will work together to protect the schools environmental health.

The environmental health of our school is not good enough. Although many students love the school very much, every day you can see many students in earnest service for schools, some pick up the garbage in the trash on the ground, some active hand at the broom sweeping the floor, and take the initiative to clean the blackboard......

But also some students could have done better in cleaning, including me, sometimes very throw rubbish casually, confetti, some classmates clearly see the floor with paper scraps, but them as invisible, this is not "ownership" of the spirit, also greatly affect the appearance of the school. Hope the students to act, "everyone to curved waist" activities, all be the master of the school, everyone starts from me, for us to make our campus environment clean and beautiful. Let people study in high quality environment so that they can get good grades.

今天我看到一篇文章名为《大家都来弯弯腰》。内容是讲,号召同学们齐心保护学校环境卫生。

联想到我们学校的环境卫生也做的不够好。虽然许多同学都非常爱学校,每天可以看到许多同学在认真地为学校服务,有的捡起地上垃圾扔在垃圾桶,有的主动拿起扫帚扫地,还有的主动擦黑板......

可是还有些同学在保洁方面做得不够好,包括我自己,有时很随便地扔垃圾、纸屑,有的同学明明看到地上有纸屑,但他们当作看不见,这样很没“主人翁”的精神,也大大地影响了学校的面貌。希望同学们行动起来,开展“大家都来弯弯腰”的活动,人人争做学校的小主人,人人从我做起,使我们的校园环境既清洁,又美丽。让大家在优质的环境中读书,这样才会取得好成绩。

A few days ago, I saw lots of uncle aunt spitting in the street.

Not, today again see a school wearing a black T-shirt uncle, he casually spit onto the ground. I quickly come forward to stop, I didnt think uncle didnt look at me, continue to go forward.

Sometimes, the grandpa in the home also can make the same mistake. Driving well, suddenly to a screeching halt, opened the window one mouthful phlegm vomit. When I stop him, he said: "it doesnt matter." But Im not discouraged, see uncle, aunt spit anywhere, I will stop them in time. Remind them to pay attention next time. If they had followed my advice, my in the mind is better than eating the honey still sweet. For example, the last time I go to the park to play, my father and mother saw a aunt walked into the grass, vomitted an one mouthful phlegm. I saw hurriedly block, aunt smiled at me and said "Im sorry, but I will pay attention next time." At that time, dont mention how much I have a sense of achievement.

Whenever grandpa didnt listen to my advice, I would reason with him. "Spit to influenza infection, diseases such as tuberculosis, harm is very big, do not only their uncivilized, also hurt others, also caused great damage to our environment." Grandpa heard my these words have never spit sputum. Mistakes can change or good comrade!

For one hundred days after the youth Olympic Games, let us work together, starts from me, do civilization from nanjing, nanjing and beauty.

前几天,我看到了由很多叔叔阿姨在马路上随地吐痰。

这不,今天放学又看到了一位穿着黑T恤的叔叔,他很随意地把痰吐到了地上。我急忙上前阻止,没想到叔叔看都没看我一眼,继续往前走。

有时,家里的爷爷也会犯同样的错误。开车开得好好的,突然来个急刹车,打开车窗吐一口痰。我阻止他时,他却说:“没关系的。”但我并没有气馁,看到有叔叔,阿姨随地乱吐痰,我就会及时阻止他们。提醒他们下次注意。如果他们采纳了我的建议,我的心里会比吃了蜜还甜。例如,上次我和爸爸妈妈去公园玩,看见一位阿姨走进了草丛,吐了一口痰。我看了连忙阻止,阿姨友好地冲我笑了一下,说“不好意思,我下次会注意的。”那时,别提我多有成就感了。

每当爷爷不听我劝告的时候,我就会跟他讲道理。“吐痰容易传染流行性感冒,肺结核等疾病,危害很大,这样做不但自己不文明,还害了其他人,对我们的环境也会造成很大的破坏。”爷爷听了我的这一番话就再也没有随地吐过痰。知错能改还是好同志嘛!

为了一百天以后的青奥会,让我们大家同心协力,从我做起,做文明南京人,创美丽南京城。
