+ 加入清单Last week, I saw a very impressive documentary about panda. A professor
studied panda in the early 1980s went to the wild life and kept trace of wild
giant panda for many years. As a result, he found that it was human being that
made these lovely animals die out. At that time, many people believed that giant
panda became less because of the low rate of newborn babies. But it was not
true. People cut trees for making profit at that time. Panda lose homeland and
they lacked of food. Thanks to these valuable data, the government took the
policy to protect the animals. So today, the number of giant panda is
increasing. People realize the importance of protecting the environment and it
is the best way to protect wild animals, they are the indispensable part of the
nature.

+ 加入清单Animals are our friends。But how to protect them? government is working to protect all animals in danger,and has made lots of plans to save animals。 On the other hand, we shouldn’t eat wild animals。We should keep them away from our dinner。 That way,there will not be wild animals on sale。 I think the hunters and killers will become fewer and fewer。
Last, we should protect the environment。We should stop people from cutting trees down。 Without trees, wild animals will lose their home。 And we will lose our animal friends。 All of us should try our best to protect animals。
We need to protect animals better。We should give them fresh water to drink。We should make the forests bigger for animals in danger to live in。We should advice people not to kill animals beacause they are our friends!

Researchers looked at climate change effect on the Arctic Sea and calculated the likelihood of this projected population drop is 71 percent.
研究人员观察气候变化对北极海的影响,并计算出预计种群下降的可能性为百分之71。
Thats because polar bears stand on Arctic Sea ice when hunting for seals. According to NASA, even the thickest ice in the Arctic Ocean has "either thinned or melted away."
这是因为北极熊捕猎海豹时站在北极海的冰上。美国国家航空航天局表示,甚至北冰洋最厚的冰要么变薄或要么融化了。

+ 加入清单It is widely noted that lots of traditional culture is disappearing along with the development of technology. Many ancient architectures and traditional ways of living have been deserted. It seems that the traditional culture and craftsmanship will be replaced in this modern era.
The following reasons can account for the above phenomenon. Firstly, traditional technologies are always considered ineffective while the new sciences are always highly efficient, because modern science and technology facilitate both our daily and academic life a lot, with which we can save much money and time. Secondly, it is costly to protect the traditional culture, especially the maintenance and repair of the historical buildings.
In my opinion, although traditional culture is an ancient heritage, it couldnt keep pace with the development of society. It is the tide of history that the traditional culture and technology will no doubt be eliminated in the end.

+ 加入清单The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.
Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.
There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.
With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.
People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

+ 加入清单野生动物”,这个词对于我们并不陌生。所以现在有很多人提倡保护野生动物。但是“保护野生动物”这个词,又有几人真正做到呢?
全世界有794多种野生动物,其中有76科300余种濒临灭绝,还有很多已经灭绝了。人们为了钱财,不断杀害它们,导致野生动物大量灭绝。直到“非典”事件发生,人们才觉悟起来……
野生动物对我们帮助很大,例如燕子,燕子能帮我们吧田里的害虫吃掉。如果没有了它们,我们的周围就会有很多害虫,这些害虫对我们人类有很大的害处呀!
有些人认为,野生动物理应被杀掉,因为有些野生动物很危险。但我想对那些人说:没错,有些野生动物的确很危险,但它们一般多在远离人类的地方,所以我们不用害怕。而且有些野生动物也很可爱,例如大熊猫就很可爱,还有软软的绒毛。
“没有买卖,就没有杀害”这则公益广告说得真好,是的,只要人们不再去销售野生动物,就不会有人去买,更不会有被残害的野生动物了。
同学们,虽然我们现在的力量还很薄弱,但千万不要小看这力量。从现在开始,去保护野生动物吧,让世界充满和平!

+ 加入清单People like to modernize the building compared to the magnificent, then this embodies a high degree of spiritual civilization and material civilization of the building should stand in what kind of environment? If the sky filled with smoke, the earth vegetation and so on, this is the people of the modern society of it? No, no, it is the irony of history, this is the tragedy of mankind.
People live on earth, to survive, to develop, first of all have to rely on the earth, by mountains and water, there are grassland nature of the forest. But some people mistakenly believe that nature is inexhaustible treasures, so deforestation and species, dried Ze and fishing, and even by the natural punishment and not know. Year after year, the forest into a barren hills, oasis into a desert, resulting in the world every year, 2,000 hectares of farmland was swallowed by the desert. So go after a few years, the earth will be all occupied by the desert green, our children and grandchildren will not survive! A few years ago, the rural package to the household, coax the mountain into the wind, Chinas Wuchuan County, a township of nearly 2,000 acres of fir forest, cut in a week for the ground. Hearing this news, I have a headache, I am angry, the farmers doing so are too ignorant and too selfish. There are a lot of things that are doing the same thing: it is the smoke of the sky, so that the noise of high decibels can stimulate the nerves of the people.
In this regard, we should think deeply. Modern society makes us live better, modern science has also fully revealed the importance of environmental protection. Every honest citizen should have such a historical vision and sense of urgency: to build our country into an ideal modern power, we must do the development of economic and environmental protection simultaneously, to achieve economic development and social benefits of unity.
人们喜欢把现代化比作宏伟的大厦,那么这座凝聚着高度精神文明和物质文明的大厦应矗立在怎样的环境之中呢?如果天空烟雾弥漫,大地草木枯败等等,这是人们心中的现代化社会吗?不,不是,这是历史的讽刺,这是人类的悲剧。
人生活在地球上,要生存,要发展,首先就得靠地球,靠有山有水,有森林有草原的大自然。可是有人误以为大自然是取之不尽,用之不竭的宝库,于是毁林而种,竭泽而渔,连连受到自然的惩罚而不自知。年复一年,森林变成了荒丘,绿洲沦为沙漠,致使世界上每年有2000公顷农田被沙漠吞噬。这样下去经过若干年,地球上的绿地将全部被沙漠侵占,我们的子孙将无法生存!前些年,农村包产到户后,哄砍山林成风,我国务川县一个乡的近2000亩杉木林,在一周之内被砍为平地。听到这个消息,我头疼,我愤怒,这样做的农民太愚昧,太自私。还有很多正在干着类似务川的贻害子孙的事情:任滚滚浓烟弥漫天空,让高分贝的噪音刺激人的神经。
对此,我们应该深思。现代化社会使我们生活得更美好,现代科学也已充分揭示了环境保护的重要性。每个正直的公民,都应具备这样的历史眼光和忧患意识:要把我国建成一个理想的现代化强国,必须做到发展经济与保护环境同步,实现经济发展效益与社会效益的统一。
事实也是这样,几年前,大连污染严重,经过一系列的保护措施后,不仅使市容面目美观了,还带来了良好的经济效益,外商投资,中外合作等等,因此让大连成为现代化的大都市。
让我们伸出自己的双手,来保护自己的家乡,来建设自己的家乡吧

I am particularly fond of small animals,. I think, they are mans most loyal friend. So, when I see others to dispose of animals, in the heart can not help but sad. My dream is to people and animals live in peace.
Now people are like to eat dog meat hot pot, I dont understand. A dogs life, it is to his own master, dont just because it is old, useless, and denied the value of its existence. This is not possible! People will also newborn puppies thrown into the lake, trash can, they are discarded, it is no good. Everyone has the right to existence significance and value, even if is a person, also not qualified to deprive their lives.
I have witnessed the cat after being hit by a car fly. The distorted face telling the pain of it. Its blood, viscera was hit from in vitro. Although the rain wash away the traces of blood, but every time I go there, mind will automatically jump out of the scene, think of the cat that broken beyond recognition, think about it before he died not look in the eyes...
Since then, I was in my heart silently vowed, to do their own efforts, to protect small animals, at least, dont let them innocent caused the death.
I think, in the future, I will set up a "happy family", there will be dedicated to adopt the stray animals, if the man willing to adopt, I will also be given to him. In this way, those who stray cat, stray dogs have a warm home. I will also for those precious endangered animal donations, not completely destroy them.
Perhaps, so I am very silly, very silly, but I am willing to do that silly to worry about in others eyes puny little animals.
If you also like me "stupid", let us firmly "silly". Because they are lovely.
动物是人类最忠诚的朋友,请不要伤害他们。
从小,我就特别喜欢小动物。我觉得,它们是人类最忠实的朋友。所以,当我看到别人随意抛弃动物时,心中不禁很难过。我的梦想就是人们和动物和平相处。
现在人们都很喜欢吃狗肉火锅,我很不理解。狗的一生,都是为了自己的主人,难道就只是因为它老了,不中用了,就否定它存在的价值。这是不可以的!人们还将刚出生的小狗崽扔到湖里、垃圾桶里,将它们随意丢弃,这也是不行的。每个人都有存在的意义和价值,即使是人,也没有资格剥夺它们的生命。
我曾经亲眼目睹了猫被车撞飞后的惨状。那扭曲的脸诉说着它的痛苦。它的鲜血、内脏被撞离体外。尽管雨水冲刷掉血的痕迹,但每当我走到那儿时,脑海就自动地跳出了那一幕,想起那只被撞得面目全非的猫,想起它死前不甘的眼神……
从那时起,我就在心里默默发誓,要尽自己的努力,来保护小动物,至少,也不会让它们无辜枉死。
我想,在将来,我会成立一个“幸福之家”,这里会专门收养流浪小动物,如果好心人愿意收养,我也会赠送给他。这样,那些流浪猫儿、流浪狗儿就有了一个温暖的家。我也会为那些珍贵的濒临灭绝的动物捐款,让它们不至于完全灭绝。
或许,这样的我很傻、很傻,但我愿意做那个傻傻的为在别人眼里微不足道的小动物担心的人。
如果你也像我一样“傻”,那让我们坚定不移地“傻”下去。因为它们都是可爱的。

however, reports about food problems have often been seen in the newspapers,
showing that people have always been concerned about what they eat every day.
The reason for this problem is that some of the food producers are too fond of
making money, leading to the result that they use whatever will make the food
look good or taste better without considering the bad consequences。 This is not
normal because people just cannot live without eating anything.
So we should take all the measures necessary to forbid the food producers
to make food that is not safe enough. Laws should be strengthened and the
government should have more control over these producers。 Only when people are
no longer worried about whether their food is safe or not can they enjoy a
better life.

篇19:如何保护动物英语作文
全文共 5272 字
+ 加入清单The dog is one of the most popular pets in the world. It ordinarily remains loyal to a considerate master, and because of this the dog has been called mans best friend. Class distinctions between people have no part in a dogs life. It can be a faithful companion to either rich or poor.
Dogs have been domesticated for most of human history and have thus endeared themselves to many over the years. Stories have been told about brave dogs that served admirably in war or that risked their lives to save persons in danger. When Pompeii--the Roman community destroyed by Mount Vesuvius in AD 79--was finally excavated, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Perhaps few of the millions of dogs in the world may be so heroic, but they are still a source of genuine delight to their owners.
A dog fits easily into family life. It thrives on praise and affection. When a master tells a dog that it is good, the animal happily wags its tail. But when a master scolds a dog, it skulks away with a sheepish look and with its tail tucked between its legs.
People in the city as well as those in other areas can enjoy a dog. Medium-size or small dogs are best suited for the confines of the city. Large dogs need considerable exercise over a large area.
Dogs are not always well thought of, however. In recent years dogs in the city have been in the center of controversy. Some people have criticized dog owners for allowing their pets to soil sidewalks and lawns, although in some cities laws oblige owners to walk their dogs along street curbs. In turn, dog owners have argued that the animals serve as protection against vandals and burglars and thus protect their detractors as well as their owners.
When a person decides to own a dog, he should be prepared to care for it properly. For a dog to stay healthy it must be correctly fed and adequately groomed, and its medical needs must be met. For a dog to be well-mannered it must be properly trained. It should never be ill-treated or mishandled. Otherwise, it will bite in its own defense.
The wild ancestors of all dogs were hunters. Wolves and other wild relatives of the dog still hunt in packs for their food. Dogs have retained the urge to be with the pack. This is why they do not like to be left alone for long. Some breeds of dogs still retain the hunting instinct.
Dogs exist in a wide range of sizes, colors, and temperaments. Some, such as the Doberman pinscher and the German shepherd, serve as alert and aggressive watchdogs. Others, such as the beagle and the cocker spaniel, are playful family pets, even though they were bred for hunting. Still others, such as the collie and the Welsh corgi, can herd farm or range animals. Each of the dogs just mentioned is a purebred. A mongrel dog, however--one with many breeds in its background--can just as easily fit into family life.
Dogs have been with humans since prehistoric times. Over the years they have performed various services. They have pulled sleds over snowy tracts. They have delivered messages, herded sheep and cattle, and even rescued persons trapped in the snow. Dogs have served as a source of food, too. The ancient Romans are said to have prized certain kinds of dog stew. The Aztecs of ancient Mexico raised tiny dogs, thought to be the forebears of the chihuahua, to feed the large carnivores in the private zoos of the Aztec rulers. In the past dogs have even been worshiped as gods. Recently, they have been used in drug research, medical experimentation, and space science. Soviet scientists launched dogs into space to test the ability of mammals to survive the rigors of space travel before people were sent up.
Dogs are trained as guard dogs in peacetime by the United States Army and other military services. Because of their keen sense of smell, dogs are used by police at times to track down escaped prisoners. Law enforcement agencies also rely on the dogs acute sense of smell to uncover illegal drugs. And specially trained dogs serve as the "eyes" of the blind, guiding the steps of their sightless masters around obstacles and hazards.
狗是世界上最受欢迎的宠物之一。它通常仍然忠于一个体贴的主人,因为这个狗被称为人类最好的朋友。人们之间的阶级差别没有生活在狗的一部分。它可以是一个忠实的伴侣,无论是富人还是穷人。
狗驯化在人类历史的大多数时期,因此球员很多。故事被告知关于勇敢的狗,令人钦佩的战争或冒着生命危险拯救的人处于危险之中。当庞培——罗马社区在公元79年被维苏威火山——终于被挖掘,搜索者发现一只狗躺在一个孩子的证据,显然试图保护这个年轻人。也许一些世界上数以百万计的狗可能是英雄,但他们仍然是一个真正的喜悦主人的来源。
一只狗容易符合家庭生活。在赞美和感情。当大师告诉一只狗,它是好的,动物快乐地摇尾巴。但当主人骂狗,它潜伏了一个羞怯的外观和它的两腿之间夹着尾巴。
城市的人们以及那些在其他领域可以享受一只狗。中型或小型狗是最适合城市的范围。大型犬在大面积需要相当大的锻炼。
然而,狗并不总是值得思考的。近年来狗在城市里一直在争论的中心。有些人批评狗主人允许宠物土壤人行道和草坪,尽管在一些城市的法律迫使业主限制他们的狗沿着街道散步。反过来,狗主人认为,动物作为防范破坏者和窃贼,从而保护他们的批评者以及它们的主人。
当一个人决定自己的一条狗,他应该准备妥善照顾它。狗保持健康必须正确美联储和充分培养及其医疗需求必须得到满足。狗必须得到适当的训练表现得彬彬有礼。它不应该虐待或处理不当。否则,它会咬自己的防御。
所有的狗都是猎人的野生祖先。狼和其他的野生亲缘狗仍然集体觅食的食物。狗有保留的冲动与包。这就是为什么他们不喜欢独处太久。一些品种的狗仍然保留了狩猎的本能。
狗存在大范围的大小,颜色,和性情。一些,比如杜宾犬,德国牧羊犬,作为预警和积极的监督者。其他的,如小猎犬和可卡犬,好玩的家庭宠物,尽管他们的狩猎。还有一些,比如牧羊犬和威尔士科基犬,可以群农场或范围的动物。每个狗刚才提到的一个纯种。一条杂种狗,然而——有许多品种的背景——可以很容易适应家庭生活。
狗自史前时代以来一直与人类。这些年来,他们已经在执行各种服务。他们已经把雪橇在雪大片。他们传递的消息,赶羊和牛,甚至救出被困在雪地里的人。狗也有担任过的食物来源。古罗马人据说炖珍贵的某些种类的狗。古代墨西哥的阿兹特克提出了很小的狗,认为是吉娃娃的祖先,给阿兹特克的私人动物园大型食肉动物的统治者。在过去的狗甚至被崇拜为神。最近,他们被用于药物研究、医疗实验,和空间科学。苏联科学家发射了狗测试能力的哺乳动物生存的艰辛太空旅行之前人打发了。
狗是训练有素的警犬在和平时期的美国军队和其他军事服务。因为他们的敏锐的嗅觉,狗被警察有时用来追踪逃跑的囚犯。执法机构也依靠狗的敏锐的嗅觉发现非法毒品。和受过专门训练的狗充当盲人的“眼睛”,指导的步骤失明的主人在障碍和危害。

+ 加入清单The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.
In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.
As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.
