我看到了一只大点的用头上的角在树上顶来顶去。我想因为那只羊的角长长了痒,所以顶树。就像小孩子长出牙要痒一样。

I saw all this. Found that pigs fate was so miserable! Is this fate arranged? Or pigs caused by past delicious lazy? I found the "people" are so cruel. Oneself have so long pig, cruel to kill it. Ah, I found that at the moment I was so sad, so sad, so lost, so helpless. In nature there are many more miserable than this things are happening, perhaps this is fate, it is inevitable in the growing of a test.
Not often say that animals are friends of human beings? Not often say that people for the ethical treatment of animals, protect the earth? Maybe this is just for those rare animals! Those animals that almost nearly perish! Pigs in a country of the world, one city, a town, a village, or even a home, a person can see. Pigs are a lot of, is not worth to treat? Pig also is to have life, and human beings, it also know pain, also have feelings, also know how sad. People for the ethical treatment of animals! The animals as their friends, for they give a little love!
Animals are friends of human beings, like humans, are the people of the earth. Let us hands reach out, to protect, to help those who need help human friends!
一个周日的下午,我漫不经心地调着电视频道。突然,惨不忍睹的一幕进入我的视线:一个农民模样的人正拿着一根铁棍敲打什么,原来是一群屠夫正在屠杀一头不怎么大的小猪。
我亲眼目睹了这一切。发现猪的命运竟是这么悲惨!难道这是命运安排好的吗?还是猪前世的好吃懒惰造成的?我发现“人”竟是那么狠心。自己养了这么长时间的猪,竟然狠心杀掉它。哎,我发现此刻自己竟是那么的伤心,那么的悲痛,那么的迷惘,那么的无奈。大自然中还有很多比这更悲惨的事情正在发生,或许这就是命运,这就是在成长中不可避免的一次考试。
不是常说动物是人类的朋友吗?不是常说善待动物,保护地球的吗?可能这只是针对那些稀有的动物罢了!那些几乎将近灭亡的动物罢了!猪在世界的某个国家,某个城市,某个城镇,某个村庄,甚至某家某户都可以见到。猪是很多,多到不值得善待?猪也是有生命的,和人类一样,它也知道痛,也有感情,也懂得伤心。善待动物吧!把动物当成自己朋友,对它们付出一点爱吧!
动物是人类的朋友,同人类一样,都是地球的子民。让我们伸出双手,去保护,去帮助那些需要帮助的人类的朋友吧!

篇7:保护珍惜动物英语作文篇
全文共 1750 字
+ 加入清单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 careBecause 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. WhyBecause 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.
中文:
动物是自然资源,在整个历史过程中,人类一直在糟蹋着这种资源。人们杀死动物,获得它们的皮毛,把它们当作食物或运动方式,或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。
为什么人们应该感到担忧呢因为我们需要动物,因为它们一旦消失,就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来
源。在维持自然平衡中,每种动物都有其作用。毁灭某种动物会导致许多问题。比如,农民们如果杀死为数众多的鹰,他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么因为鹰吃鼠类,没有鹰控制它们的数量,鼠类就会迅速繁殖。
幸运的是,有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。
篇8:关于保护动物的语文作文高5
全文共 633 字
+ 加入清单今天,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保护动物作。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!"

+ 加入清单蔚蓝的天上有小鸟飞过的身影;树上有鸟儿婉转的歌唱······我救过一只翅膀受伤的小黄莺,等它伤好了我便放了它,它依依不舍得的绕着我转了一圈又一圈。我目送它飞走后,惊奇地发现自己能听懂动物的语言了。
朋友家有一只美丽的小鸟,我刚走过去,没想到小鸟主动开口了:“你好!救救我吧!你们人类让我们妻离子散,失去家园,还把我们关进了笼子里,让我们不能展翅飞翔!”我听了沉默不语,心里有一些内疚。小鸟见我不说话便接着说:“我的小妹妹才刚出生十几天就被一个人类捉走了;我的舅舅在觅食时被打断了一条腿;我的妈妈正在四处逃亡······不知道它们现在怎么样了,我想它们,我想回家······”小鸟说着说着哭了起来,我便觉得更内疚了。朋友见我一个人呆呆的站着一动不动,觉得很奇快,便问我:“你
怎么了?”“你把小鸟放了吧!”我恳求地说。“为什么?好好的放了干什么?”“你想过没有亲人的生活吗?失去了亲人你不会害怕吗?让它走吧!让它从新投入家人的怀抱吧!”我的朋友不说话了,显然我的话打动了她。她毅然的打开笼子放走了小鸟,小鸟临走前对我说:谢谢你,我会再来看你的!"
看着小鸟重获了自由,我十分开心,回到了家,突然发现了那只被刚刚放走的小鸟,它对我说:“你能帮我救出我妹妹它们吗?他们一定也不习惯这样的生活!”我答应了,同时让它带了封信给它们的女王。告诉它们我不会让人类再捕捉小鸟,把小鸟的自由夺走的!
我觉得光靠我一个人是没有用的,因为小鸟被捉得太多了!于是我来到电视台,再找了几只小鸟,它们面对电视台个个说得
十分感人,把我这个翻译都感动过的哭了。
这个方式果然有用,只要看了电视,听了广播的人都把自己家的小鸟放了并劝别人家也把小鸟放了。
现在,蓝色的天空中又能重新看见鸟儿展翅飞翔的身影;茂盛的树上又有鸟儿在安居了,在树下还能听见鸟儿的欢歌;在
草坪上还能看见鸟儿在觅食······此时,处处是鸟影,我希望这样的景象能永存下去!

你们知道大熊猫怎么消化竹子的吗?科研人员发现,大熊猫的消化道粗短而又简单,没有一般食草动物细长的肠道和复杂的胃或发达的盲肠。此外,在大熊猫的基因序列于2009年公布之后,他们还发现大熊猫消化道内缺乏一些帮助食草动物消化纤维素和半纤维素(它们是纤维性植物饮食的主要成分)的酶。这让科研人员感到非常困惑,缺乏这些必要条件的大熊猫是如何消化竹子的呢?
科研人员利用基因测序技术,分析5000多个核糖体RNA序列,最终在大熊猫体内发现了多种消化道微生物,而且和一些食草动物体内的微生物非常类似。这些都有助于动物消化体内的纤维素,而且其中有了7种是熊猫消化道内独有的。拜拜!

The sun to see everyone to the Qi, and clear the clear voice, said: "The stars, our good sister earth has been at stake, the doctor said that her blood is toxins, the body of nutrients is also depleted, in this way "The moon says," In recent years, mankind has mined a lot of oil, minerals, wood and other materials, without protecting the environment, and the earths sister is not sick. "Saturn says" Way, we save the earth together! "" Well! "The stars have promised.
After the stars go back, have heard of human beings looking for a second home, so have made an appointment, never the second home of mankind, have also thrown away the conditions may be human use. For example: the moon threw away the oxygen, Saturn threw away the appropriate temperature, Mercury thrown away ... ... Finally, the human consciousness that the earth is the only human home, carried out to protect the Earth action.
300 years later, the sun also held a meeting, the earth also participated, she looks beautiful, green skin, clean blood, more importantly, she becomes healthy, the moon said: "sister, see you now So happy, I am happy for you. "Mercury said," Sister, see you now so beautiful, I am a little jealous. "Earth said:" Thank you all for my sacrifice so much, I am now healthy, or Thank you all, thank you, "said the sun," the stars, after this action, humans have recognized the importance of the earth, and I declare that the rescue of the earth is a success.
Friends, the mother of the mothers disease though good, but also need to continue convalescence, and now, let us work together to the earth dressed as the most beautiful planet in the universe.
There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.
Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."
Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.
