There are more high-rise apartment buildings built in the city we live to accommodate more city dwellers. To make room for these constructions, a large number of trees are cut down. We have to be constantly afflicted with the noise and air pollution everyday. Obviously, we are paying the cost of the development.

Even the most developed countries are troubled with environmental issues. In fact, the more developed the country is, the severer the problem has. To maintain our economy prosperity and stability, we have to be in full operations and spread the workload in industry fields. As a result, we may seek temporary economic development at the expense of the environment and resources. The consumption of natural resources has been a big problem. It is admitted that the world economy is booming with the satisfaction of environment. However, we have made a blunder by equating material prosperity with better living standards.

A better life should be a life closer to nature. The modern lifestyle is best characterized by hectic, mass-productive and seemingly comfortable. But actually something originally natural and invaluable has been lost. We are no longer able to breathe fresh air, take a walk in the woods or even look at the stars in the sky as the stars are obscured by smog and artificial lights.

Hence, we need to curb the quick tempo of life in order to protect our environment and ironically improve our life. Science and technology thus should be employed to create a harmonious relationship between mankind and nature. A better environment means much more than material comforts. Besides, by slowing down a little bit, our life would turn out to be less stressful. To have a better life, we need take effective measures right now.

The current environment damage stems from the misguided conception that material wealth is equivalent to a better life. In reality, environmental protection serves as the catalyst of our very pursuit of better life rather than a deterrent 关于环境保护的英语作文2

Many people believe that we have developed into a “throw-away society” which is filling with plastic bags and rubbish. What do you think?

Wind blows up bags higher and higher in the sky. It is a scary thought that some day the earth will turn into a huge garbage land. Wastes, if not treated properly, will make our life a living nightmare.

The environmental issue is getting worse almost every day in cities with very large population. As is often the case, city development outpaces environmental protection. People consume great amount of natural resources and produce wastes. To effectively address such problems, cities need to spend big money. In addition, they need to call to the attention of people to become more environmentally responsible.

Many people are becoming less responsible and easily influenced by bad behaviors. “Why should I care while others shouldn’t?” Such idea makes some people only concern with places where they live and work. Furthermore, people sometimes even purposely litter for revenge to other people.

Although media promotes environmental awareness, good people are often snubbed as posers who try to set up a superior image in real life. Consequently, they are intimated of receiving negative comments for doing the right thing. Wrong as it is, such phenomenon is widespread especially among youngsters and people with low income and little education.

However, our society is waging a campaign against environmental pollution. People learn the harms of un-degradable lunch boxes and other polluting wastes. Laws in many countries prohibit or limit excessive use of polluting bags. Companies are continually replacing the old materials with more environmental friendly and recyclable kinds. Scientists have developed more effective technologies in waste treatment. As time goes by, more and more people put high priority on the protection of environment for a healthier life.

To sum up, people produce huge amount of garbage and the environment is seriously polluted because of lack of financial resources, sense of responsibility, or efforts. But the world will not turn into a “throw away” society if people put in sufficient efforts to protect our environment

导语：你最喜欢的动物是什么呢?下面是yuwenmi小编为大家整理的相关英语作文，欢迎阅读与借鉴，谢谢!

My favorite animals are swans.they are white.they can swim very well.I think they look like a beautiful girl in a white dress.They have a pair of wings and they can also fly well.I believe they are angles from the sky.they bring us love and make us happy.They are always friendly to us.We cant hurt them,because they are our friend.I love them!I like dogs,too.they are not beautiful,but they are the best friends.they keep the thieves away.Dogs have the best listening and eyes.they can hear in the nosiy,see in the dark.If we are in danger,they will help us at once.And they dont mind their lives.So,I love them.

【参考翻译】

我最喜欢的动物是天鹅都是白色的可以游得很好。我认为他们看起来像穿着白色衣服的美丽的女孩，有一双翅膀，它们也会飞。我相信他们是从他们的角度给我们带来爱和快乐。他们一直对我们很友好。我们不能伤害他们，因为他们是我们的朋友。我爱他们!我喜欢狗，它们不美丽，但他们是最好的朋友，把小偷吓跑了。狗有很灵敏的眼睛能听到在闹市，在黑暗中看到。如果我们有危险，他们会立刻帮助我们。他们不介意自己的生活。所以，我爱他们。

今天，我读了《白耗牛》一书，受益匪浅。

《白耗牛》讲述的是这样一个故事：在一个牧场里，丢失了一只珍贵的耗牛。这时，，个叫贡嘎的学生，要为玛尔吉阿婆找回这只白耗牛。他翻山越岭终于从一个守林人那里了解到白耗牛被偷到了长岭山的牧场，还得知牛贩子康劳要杀白耗牛。他只身勇闯虎穴，终于从康劳的手里抢回了白耗牛。

读了这个故事，我想：“连个学生都能这样为国家保护珍贵动物，而现在很多人却随便捕杀野生动物，破坏环境，使动物们生存受到了威胁。”

我曾在电视上看到这样组镜头：非洲草原土，横七竖八地躺着被割去象牙的非洲象，周围一片鲜血；一条肮脏的冒着白泡的河流中，漂着一条一条死鱼；还有被关在笼中的猴子……

记得有一次，爸爸带我们到饭店吃饭，我忽然看见了饭店一角关着两只穿山、甲，鱼池里还有中华鳃，这些可是国家保护动物啊！怎么能被吃掉呢？

这不禁让我回想起了我看过的一部纪实影片：一只活泼可爱的小猴子被关到了一个特别的笼子里，只露出一个脑盖来，侍者拿出锤子对着脑盖敲了几下，小猴的脑盖便开了，而那些可恶的客人竟然用热水烫过的勺子舀着猴脑吃。小猴在那里大声惨叫着……

这是为什么？人类本应与自然和谐共处，但有些人却为了金钱，不择手段，屠杀手无寸铁的动物。从此，大自然的生态平衡被破坏了。

地球已经千疮百孔了，如果我们人人都像贡嘎一样，那么很多珍稀的动物也不会灭绝，动物们也不会向人们苦苦哀求了！

朋友们，快清醒吧，动物是人类的朋友！我要大声呼吁:“保护动物，人人有责，让我们共同保护我们的家园吧！"

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

Water is the source of life, life, human health without water. Few people can not eat, but you cant days without water. And now, global 20 million people are in severe water shortages!!!!!!!!!! Water crisis, has to humans was a wake-up call!

Chinas water resocurces, but most of all, is the sea water of the sea is salty, is not directly drinkable, Plus most all freshwater distribution in cold north and south poles and permanent snow mountain, this place is freshwater resources. And uneven distribution, east of north, south west of less than, the local water.

When I was a child I want to tap water, water has been flowing nonstop not? Mom and dad always told me what was recently and drought.

Each year, people burn or cut down 143,000 square kilometers (55,000 square miles) of the forest. People who burn or cut down trees do it for different reasons: farmers cut down trees in order to get more fertilize lands to grow rice or vegetables, and use the woods as fuel. Timber companies cut down trees and turn them into furniture or paper productions. As to goal miners, they remove the forests to find out whether there are goal underground.

每一年，人们都会砍伐14.3万平方千米的森林(约5.5万平方英里)。人们砍伐树木出于种种原因：农民们为了得到更肥沃的空地来种植大米蔬菜，砍下的树木用来取火。木材公司用树木来制作家具或是各类纸制品。至于那些开采煤矿的人，把树木砍掉就是为了检测是否有煤矿在下面。

However, many of us fail to realize that forests are the lungs of the earth. When we cut down trees, we also push ourselves in to a dangerous situation. That is the global warming. When you come to think about it, there are only few ways to solve these negative effects: stop cutting down trees blindly; try to find some clear energy that can replace oil and coal. But these solutions can be impractical to some degreed.

然而，我们中的许多人都没有意识到树木等同于地球的“肺部”。当我们砍伐树木时，我们就把自己推入一个危险的境地——会引起全球气候变暖。想到这些，只有为数不多的几个办法可以解决这个问题：停止盲目地砍伐树木;寻找可以代替石油和煤矿的新能源。但是，就目前来看，这几个策略并不可行。

Why trees can be so important to the whole nature? First of all, trees are the habitat of many animals. When we cut down trees, we not only destroy animals’ habitats but also ourselves. We just gradually destroy natural links. The result is that many spices of animals and plants are dying out. Secondly, cutting down trees cause global warming, to some degree. Naturalists compare forest to human’s lungs. The forests absorb the carbon dioxide and other gas that cause global warming, and then give off the oxygen that good for the human beings and other living creatures. It’s refreshed the air as well as reduced the noise. If the air quality is bad, people may die from cancers, or the new diseases for which they have no immunity. Forests also play an important role in the prevention of natural disasters. Warmer temperatures cause water to expand and also create more water by melting polar ice caps. That’s to say, the nations which near the ocean may have been flooded by the water. But the forests can prevent water loss and soil erosion, and cool off the global temperatures. It’s the key to keep the balance of the nature.

为什么树木对整个生态环境都如此重要呢?首先，树木是小动物们的家园。当我们砍伐树木时，我们不仅仅毁掉了它们的家，也毁掉了自己的。一步步的，我们慢慢分解了整个生态链，所造成的结果就是大批的动植物种类灭绝。其二，砍伐树木在某种程度上造成全球变暖。生态学家把森林比作人类的肺。森林能够吸收二氧化碳和其他引起气候变暖的温室气体，然后转化成氧气供地球上的生物呼吸。树木不仅能净化空气，也能减少噪音。如果空气质量下降，那么人们就有可能死于肺癌，或者是其他致命菌。森林在预防疾病的过程中起到了重要的角色。气温的上升导致北极的冰层融化，水平面上升。也就是说，临海的城市也许会被海水淹没。但是森林就能够阻止水土流失，使气温下降。它是保证全球生态平衡的关键。

Sometimes people only care about money making; they don’t care about the price we pay for the pollution. When the disaster is around the corner, we may be afraid and frustrated. The earth, on which our economies have always been based, is suddenly threatening our existence. All we hope that is this overpopulated, over industrialized planet can carry on for a longer time. And maybe, it’s time for us to realize that we should protect the earth, stop cutting down trees blindly and madly.

有时候人们只关心挣钱，却对我们所付出的代价不管不问。当灾难来临时，我们会害怕、会彷徨。我们赖以生存的地球，却突然变成了威胁我们生命的东西。我们只希望，在这个人口过度、工业过度的星球能继续撑下去。也许，是时候我们应该保护地球，停止盲目疯狂地砍伐树木了。

Nowadays, the environmental protection is becoming one of the most important issues in the world. Being one of the members of our society, what shall we do to protect the environment

First, stop using plastic bags, boxes and bottles. Stores should be required to use the bags, boxes and bottles which are made from paper. Secondly, more and more trees and flowers should be planted to keep our surrounding clean. People must be required to plant plants around their houses and work places.

Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present.

Since the first day, BNBM has paid more attention to protect the environment as its social responsibility, by developing green building materials, producing green products and creating green enterprise. According to the spirit of "From the nature, for the nature and return to the mature", BNBM has tried its best in developing new technology and improving equipment to reduce the pollution.

"Protecting the environment, purify our living space!" This sentence, has become a new era of the loudest slogan! We also want to environmental protection dedicate a force.

As people living standard gradually improve, more and more is also high to the requirement of articles for daily use. Some factories in order to their own interests, the discharge of waste water in the clear brook; The waste gas into the forest. Forest gradually wither, the stream pollution gradually, some animals and humans died for drink a lot of filthy water, it is harm to our living environment! Now, forest gradually reduce, each factory is gradually increased; Green is gradually reduce, gray is gradually increase. People only consider their own interests, completely regardless of the environment. Wake up! Hurry to take action to protect the environment!

Because of pollution, our blue sky no longer blue; White clouds because of pollution, we no longer; Because of pollution, the tree that we no longer live... Everything, all from a word, the pollution. The pollution, is the only interest, not for bad people!

Because of pollution, the earth mothers pale and gaunt; Because of pollution, the earth mothers body, has been scarred; Because of pollution, the earth mother has no original color; Because of pollution, the earth mother has... Wake up! Those ignorant people, also we a piece of green Spaces! Act quickly! Take an active part in health activities, protect the environment! Even if its just picked up a plastic bag from the ground, it is also the love the earth mother to do...

Once again remind of our slogan "environmental protection, purify our living space" dont let the noise of the earth into the second moon...

“保护环境，净化我们的生活空间!”这句话，已经成为新时代最响亮的口号!我们也要为环保献出一份力量。

随着人们生活水平的逐渐提高，对生活用品的要求也越来越高。一些工厂为了自己的利益，把排出的废水倒进清澈的小溪里;把废气排进森林里。森林渐渐枯萎，小溪渐渐污浊，一些动物和人类因为喝不少不干不净的水而死去，这已经危害到了我们的生活环境!现在，一片片森林逐渐减少，一座座工厂在逐渐增加;绿色在逐渐减少，灰色在逐渐增加。人们只顾及自己的利益，完全不管坏境。醒醒吧!赶快行动起来保护环境吧!

因为污染，我们的蓝天不再蔚蓝;因为污染，我们的云朵不再洁白;因为污染，我们的大树不再茂盛……这一切的一切，都来源于一个词语——污染。这污染的元凶，就是那些只为利益，不为坏境的人们!

由于污染，地球妈妈的脸色变得苍白、憔悴;由于污染，地球妈妈的身上，已是伤痕累累;由于污染，地球妈妈已经没有原来的色彩;由于污染，地球妈妈已经……醒醒吧!那些无知的人们，还我们一片绿色的天地!快快行动起来吧!积极参与卫生活动，保护环境吧!哪怕只是从地上捡起一个塑料袋，也是爱地球妈妈的表现……

再一次想起我们的口号“保护环境，净化我们的生活空间”不要让地球变成第二个月球……

现如今各大城市的酒店招牌上都写着“今日推出__鲨鱼鱼翅，__鳄鱼肉”等等可你们有想过吗?如果有一天这些动物都灭绝了会怎样?

现在濒临灭绝的动物有上百种，无论灭绝哪一种都是对生物链的一种破坏。现在是这些动物濒临灭绝，下一个是不是我们人类呢?如果每人少吃一对鱼翅就能留住多少只鲨鱼?我见过人们把鲨鱼的鳍残忍的割了下来，又把鲨鱼放了回去，血染大海。你们有想过鲨鱼没有了鳍它们还活的下去吗?鲨鱼没有了鳍就像人没有了胳膊和腿。人没有了腿和胳膊生活就不能自理，鱼也是如此。现在人类找不到鲨鱼便用鳐鱼的鳍来顶替，这多么残忍。

象牙是大象的牙齿，象牙对大象很重要。但不知从何时开始，象牙制品很受人们欢迎。人们又为了钱不择手段的获取象牙，使每年的大象数量急剧减少。象牙制品在市场上的价格很高，正是这样使更多的人去猎杀大象。

在一篇电视报道上我看到人们把一只成年雄性大象捆起来生生地锯掉它的象牙后，把大象扔在一旁，我清清楚楚的看到这只大象在默默流眼泪，它没有发怒，因为它怕再受到伤害。它的后面是一群人得到了象牙的大笑声。

女人是爱美的，当你们用着蛇皮制成的皮包，貂毛制成的大衣，狐狸毛制成的围巾等等。有想过这些动物被去皮时的痛吗?一碗鱼翅汤就要买到上千元，一款皮包，一件貂皮大衣，一条围巾都价值不菲。在人类中这些东西属于高档衣物或食品。是为了什么?仅仅是为了满足自己的味蕾?仅仅是想自己穿的暖一点?

人类的非法捕杀已经让野生动物寥寥无几，我相信只要大家不再非法捕杀这些野生动物，不再买这些野生动物制成的东西。野生动物一定会再兴盛起来。

保护野生动物一定会让生活变的更美好!

Animals are peoples friends, we should protect them.

If there is no animal on earth, there would be no human. Animal is a most of the earths food chain, if animals disappeared, we human beings will be extinct. For example: the frog disappeared, there is no animal pests to catch paddy fields, crops will not grow, humans have no food; If there is no tiger, the rabbit will excess breeding, our food is likely to be a rabbit eat didnt; If there is no owls, mice will encroach on our territory...

The earth is a big family, not lack of anyone, without animals, we humans situation, we should all band together and protect small animals.

动物是人们的朋友，我们应该保护它们。

地球上如果没有动物，就没有人类。动物是这个地球生物链的一大部分，如果动物消失了，我们人类也会灭绝。例如：青蛙消失了，就没有动物去捉稻田的害虫，农作物也就无法生长，人类就没有食物;如果没有老虎，兔子就会超额繁殖，我们的粮食就可能会被兔子吃没了;如果没有猫头鹰，老鼠就会侵占我们的地盘……

地球是一个大家庭，缺谁都不行，如果没有动物，我们人类的处境可想而知，我们大家应该团结起来，保护小动物。

April Fool"s Day is traditionally a day to play practical jokes on others, send people on fool"s errands, and fool the unsuspecting. No one knows how this holiday began but it was thought to have originated in France.

传统上来讲，愚人节这一天，人们可以相互搞恶作剧，骗人跑腿，欺骗不知情的人。没人知道这个节日是怎么来的，但人们普遍认为它源自法国。

The closest point in time that can be identified as the beginning of this tradition was in1582, in France. New Year"s was celebrated on March25and celebrations lasted until April1st. When New Year"s Day as changed from March25to January1st in the mid-1560"s by King Charles IX, there were some people who still celebrated it on April1st and those people were called April Fools.

庆祝愚人节最早是在1582年，在法国。那时，当时法国新年是在3月25日，一直持续到4月1日。16世纪60年代中期，国王查理九世把新年从3月25日变为1月1日，而还有一些人在4月1日过新年，这些人就被称作四月傻瓜了。

Pranks performed on April Fool"s Day range from the simple, (such as saying, "Your shoe"s untied!), to the elaborate. Setting a roommate"s alarm clock back an hour is a common gag. The news media even gets involved. For instance, a British short film once shown on April Fool"s Day was a fairly detailed documentary about "spaghetti farmers" and how they harvest their crop from the spaghetti trees. Whatever the prank, the trickster usually ends it by yelling to his victim, "April Fool!"

愚人节那天的恶作剧有的很简单(比如，说句“你鞋带开了!”)，有的却是精心设计的。把室友的闹钟往后调一小时是常见的。甚至新闻媒体都来凑热闹。比如，在愚人节那天，曾经有一部英国短片较为详细地记录了“种意大利面的农民”，以及他们如何从意大利面树上收获意大利面。不管是什么恶作剧，搞恶作剧的人通常在最后会对被搞的人喊一句:"四月傻瓜!"

April Fool"s Day is a "for-fun-only" observance. Nobody is expected to buy gifts or to take their "significant other" out to eat in a fancy restaurant. Nobody gets off work or school. It"s simply a fun little holiday, but a holiday on which one must remain forever vigilant, for he may be the next April Fool!

愚人节是一个“仅为娱乐”的节日。谁也不用买礼物，也不用带着男/女朋友出去到一家豪华餐厅去吃饭。人们也不会放假。它仅仅是个搞笑的小节日日，但是在这一天，每个人都要保持警醒，不然就要被人耍啦。

I have a pet. It is aPigeon. It has got white and gray feathers, a red mouth and two small eyes. It’s cute.

I found it near a park. Its leg was injured and couldn’t fly. I took it home and cured it. Every morning, I give it some water and small pieces of bread. It gets stronger and stronger.

Now the pigeon has become my best friend. When I come home from school, it always flies to me and rests on my shoulders, it likes to talk to me. It makes my spare time colorful.

【参考翻译】

我有一只宠物。它是一只鸽子。它有白色和灰色羽毛，一个红色的嘴和两个小眼睛。很可爱。

我在公园附近找到的。它的腿受伤了不能飞。我把它带回家治愈它。每天早上，我给它一些水和小块面包。它变得越来越强壮。

现在鸽子成了我最好的朋友。当我从学校回家的时候，它总是飞到我的肩上，它喜欢和我说话。它使我的业余时间丰富多彩。

说到大熊猫，大家一定都很熟悉，因为它是我们国家的国宝。但是说到它的习性，大家就不一定都知道了。下面，我就给大家讲一讲大熊猫的生活习性。 大熊猫胖乎乎、毛茸茸，满是白毛的脸上带着两个黑眼圈，憨态可掬。

大熊猫性情温顺，一般不会主动攻击其它动物。遇到危险时，大熊猫也没什么方法保护自己，只能赶快逃跑。逃不掉的话，它就会像害羞一样，用前爪蒙住脸，希望敌人看不到自己。 大熊猫天生喜欢吃竹子，鲜嫩多汁的竹笋更是它的美味佳肴。吃东西的时候，大熊猫会想人一样坐在地上，用有力的牙齿把食物咬碎。吃饱了还要喝水。大熊猫喝水可不像小猫一样舔舔了事，它经常一喝再喝，一直喝到走不动为止，然后就干脆倒在小溪旁睡觉，醒了还能继续喝呢! 大熊猫每胎2至3个，刚出生的熊猫宝宝非常小，只有妈妈体重的千分之一。两岁时，小熊猫才能离开家独立生活。

怎么样，听完了我的介绍。你们是不是对大熊猫有了更深的了解了呢。最后我们一起呼吁：“保护大熊猫，让它们永远和我们在一起!”

周末，妈妈带我们去海洋世界，让我印象最深的是海龟。

海龟非常可爱，长了一个大大的元宝头，可卖萌了！它的四肢就像船桨，在水中一摇一摆地游动，就这样，身子也游得一上一下，就像在跳不合拍的广场舞。海龟是爬行类动物，在陆地上产卵。雄性尾巴长，体长的二分之一。海龟以鱼类、海藻等为主要食物。海龟还是国家二级保护动物呢！

我在海洋馆的海龟池看到了很多的海龟，它们是那么可爱，可是我看到了一些小朋友不好的行为。比如，用小棍子去弄海龟的头和背，旁边有人制止了，他们也不停，继续作弄海龟，搞得这些海龟很狼狈的样子……

看到这些，我想到了我们家的小乌龟，我想我们一定要保护海洋动物，特别是国家保护动物，以后我也会对小乌龟更加关心的。
