一天,兰兰出来透透气,她的小猫也跟在后头。突然,一个黑影子掠过眼前,“哦,是一只小燕子!”兰兰在院子里好奇地来去,“咦?燕子窝在哪儿?”她便好奇地找了起来。
她终于在一丛桃花旁的墙壁上找到了燕子窝。

+ 加入清单昨天放学时,天气非常炎热,我下楼没看见爷爷,就借同学手机打了个电话,然后我等了几分钟,爷爷就来了。
我上了车一边与爷爷闲聊,一边看着路边的风景。
突然我看到公路上有一个毛茸茸的小东西,是老鼠吗?怎么可能,怎么可能有这么大的老鼠,我又仔细看了看,这小东西正摇着它那蓬松的大尾巴,呀!是松鼠!太神奇了,居然在大马路上看见了松鼠。它好像要过马路似的左顾右盼的,好像不怕人,我们电瓶车走过,也没有引起它的恐慌。这时一辆路虎朝它飞驰而来,我心里一阵担忧,心跳顿时加快,仿佛有什么大事情要发生似的。一瞬间这辆路虎飞快超过我们,也穿过了这只松鼠,一声清脆的咔嚓声传入我的耳膜,是那样的惊天动地,我看着松鼠在半空中翻了几圈又啪的一声掉在路上,就一动也不动,一点生息也没有了。顿时一种莫名的悲伤涌上了我的心头。为一个鲜活的生命逝去而痛心。
也许这个司机是无意的,没有看见松鼠。也许这只松鼠太相信人类了,认为大家都喜欢它,不会伤害它。可以惨剧确确实实在我眼前发生了,难道不能引起我们思考吗?
在我国青藏高原可可西里这个无人区里生活着许多藏羚羊,在修建天路时怕火车影响藏羚羊的迁徙,设计者们想出了在那里架设铁路桥,这样火车在上面过,藏羚羊从下面迁徙,人与自然在这里完美可以结合。这是保护稀有动物的极好例子啊!
在澳大利亚生活着许许多多的动物,动物在马路上走对于这里的人们不足为奇,司机们开车遇到动物还要主动给它们让路。这在当地是人们自觉的行为,体现了他们的爱心,所以在澳洲这块土地上才会有那么多的动物与人和睦相处。他们的行为难道不值得我们仿效吗?
现在的环境越来越好,动物朋友们会随时和我们邂逅。对于那些不期而遇的朋友,我们除了惊喜,当然还要注意保护它们。我们司机朋友在路上,不仅要避让行人,也要避保护它们,这也是我们社会文明社会进步的表现。

保护动物的作文300字一
听说过树虎的故事吗?人们用胶水先粘住一只树虎,然后借助他们善良的本质,引来更多皮毛昂贵的树虎。这对世界的霸主----人类可谓是极大的耻辱!
从小,我就是和小狗一起长大的,因为狗是人类最忠诚的朋友。我和奶奶在一起时常常看见奶奶无缘无故的踢小狗,每当这时,我都会对奶奶大吼大叫:“奶奶你怎么能踢小狗呢?”可奶奶又怎么能听得进去呢?看着这只可怜兮兮的小狗,我不禁鼻子一酸:因为我们是人类就能在地球是为所欲为了吗?难道小狗就没有尊严吗?对那些自以为是的人类,我无可奉告!动物是人类最忠诚的朋友啊!

保护动物的作文300字二
我们要保护小动物,特别是小鸡这类弱小的动物,因为小鸡早晨可以叫我们起床,可以生一个又一个圆圆的的鸡蛋,还可以提供鸡肉给我们吃。
有一次,我和妈妈上菜市场,听见一位老奶奶在喊:“卖鸡了,今天的鸡又肥又嫩!”妈妈说:“今天,我们买一只鸡回家,炖汤喝。”我说:“好吧。”可又想了想:如果我们吃了鸡,那么就吃不到鸡蛋了,就对妈妈说:“不行,吃了鸡就没有鸡蛋吃了。”“傻孩子,你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡,只见她拔下鸡脖子上的毛,拿刀用力地在鸡脖子上划了几下。血喷向了四周,鸡挣扎了几下就死了。“太残忍了,我不要吃鸡!”我向妈妈大声的抗议。“好吧,不买了,我们就去买点蔬菜吧。”也许妈妈也觉得残忍,就同意了。
假如我们的生活中没有了动物,世界就会变得很孤独。我们要保护动物,从自身做起:少吃肉类食品,少穿皮衣毛衣;看见别人欺负动物,要勇敢地站出来劝说他们。
保护动物,人人有责!

+ 加入清单亲爱的人类:
你们好!
不知你们是否看到过这样一副画面:广阔的蓝天,飘着朵朵白云;郁郁葱葱的山林中,一只只活泼可爱的小动物欢快地跳跃着、奔跑着。这是一副多么美好的画面。然而,现在这样的画面少得可怜,更别说能亲身与小动物们接触了。这是为什么?是因为人类对大自然的破坏——大肆砍伐树木,盲目地猎杀动物。
无知的人类呀,同样是生命,只不过一个是主宰者,一个是动物,却有如此大的区别。难道已丰衣足食的我们,非要忍心让他们无家可归?同样是生命,难道就不能与他们和谐共处?我难以想象,再这么下去,只剩下了孤独的人类地球会变成怎样?世界会变成怎样?在一片荒凉的大地上没有一丝植物的踪迹,昔日的小精灵也不知去向,大地一副死气沉沉的样子。风沙来了,没有办法;寂寞难熬,也没有人让你吐诉心声的。动物也是有感情,也是有心声的,假如换作是你,看到家园毁灭,伙伴去世,还会无动于衷吗?除非你是用铁做的心。但是,动物们只有默默无声地忍受着,忍受着命运如此不公的安排,没有一丝怨言,任凭生命中的每一样宝贵的东西消失,却毫无办法。人类啊人类,难道你们还没有觉悟吧?
“退一步海阔天空”,让我们从现在开始,从身边开始,从一草一木开始,为动物们,也为自己创造一个美好的家园!相信在不久的将来,小动物,小精灵,将成为我们生活中的不可或缺的乐趣,我们互相倾诉心声的好朋友。
努力吧,每一位有血有肉的中国人!

+ 加入清单Environmental pollution can cause direct damage and impact to ecosystems, such as desertification and forest damage, which can also cause indirect hazards to ecosystems and human societies. Sometimes the harm of this indirect environmental effect is greater than the direct hazard caused by it, It is more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone depletion are the environmental effects derived from atmospheric pollution. This environmental effect derived from environmental pollution is lagging behind, often at the time of the occurrence of pollution is not easy to be perceived or expected, but in the event of environmental pollution has been developed to a very serious point. Of course, the most direct and most environmentally conscious consequence of environmental pollution is the decline in the quality of the human environment, affecting human quality of life, physical health and productive activities. Such as the citys air pollution caused by air pollution, peoples morbidity and so on; water pollution so that the deterioration of water quality, drinking water quality generally decline, threatening human health. Serious pollution incidents not only bring health problems, but also cause social problems. With the increase in pollution and peoples awareness of the environment, due to pollution caused by population disputes and conflicts increased year by year.
Let us all love nature, love the earth, hand in hand, shoulder to shoulder, heart to cast a green embankment, to defend the resources, to defend the environment, to defend the earth, to defend our beautiful home now!
环境污染会给生态系统造成直接的破坏和影响,如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害,有时这种间接的环境效应的危害比当时造成的直接危害更大,也更难消除。例如,温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性,往往在污染发生的当时不易被察觉或预料到,然而一旦发生就表示环境污染已经发展到相当严重的地步。当然,环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降,影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊,人们的发病率上升等等;水污染使水环境质量恶化,饮用水源的质量普遍下降,威胁人的身体健康等。严重的污染事件不仅带来健康问题,也造成社会问题。随着污染的加剧和人们环境意识的提高,由于污染引起的人群纠纷和冲突逐年增加。
让我们都来关爱自然,热爱地球吧,手挽手、肩并肩、心连心地铸起一道绿色环保的大堤,捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!
保护环境英语作文篇2
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 in to 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 soon. We hope that all these measures will be effective and bring back a healthful environment.

我们必须面对现实,采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题,大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。
保护环境英语作文篇3
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。

环境保护,这个话题,可以说是家喻户晓,人人皆知。但在现实生活中,一些人还是不太重视,认为微不足道,在我看来,环保要从件件小事做起。我就经历过这样两件小事:有一天,我去超市买东西,快到超市门口时,看见有几个散发宣传单的,见人就给,见车就放,可是有些人却不要,随手就扔地上,我过去将纸扔进垃圾箱里。又看见两个人用胶水将宣传单贴在墙上,远远望去,活像一块块“牛皮癣”趁他们不注意,我又拿出我的绝活“撕纸功”,哈哈,“牛皮癣”被我除掉了一大片。还有一次,我在楼底玩,发现远处草地上冒出了缕缕白烟,走近一看,原来,是我们班一群小孩在那里点火烧草,草黑了一大片,我以大哥哥的身份连忙制止,并讲了火灾的危险性和环保的重要性。他们羞愧难当,赶忙从附近端来水把火熄灭,结束了烧草行动。
我们人类都生活在一个星球上,那就是地球。地球上,有供我们呼吸的氧气,还有茂密的森林、辽阔的草原、无边无际的海洋、各种各样的动物,构成了美丽的大自然。
我想大声呼吁人们:地球属于我们人类,属于我们大家,只要用我们的双手,从我做起,从人人做起,保护环境,爱护地球上的自然资源,让清澈的塘水依旧流淌在家乡,让花儿依旧那样鲜花盛开。
人类啊,是应该觉醒的时候了,睁开眼,看看我们的周围,这是我们的家园啊,让我们从此金盆洗手,用自己的双手,用自己的智慧,用自己的良心,为我们的子子孙孙留下一个和谐、美丽的家园吧,让我们为我们世世代代的绵延生存做出一份努力吧!

篇12:保护野生动物的建议书
全文共 1076 字
+ 加入清单广大市民朋友们:
大熊猫是世界上最珍贵的动物之一,主要分布在我国的四川、甘肃、陕西省的个别崇山峻岭地区,数量十分稀少,属于国家一类保护动物,称为“国宝”。
它不但被世界野生动物协会选为会标,而且还常常担负“和平大使”的任务,带着中国人民的友谊,远渡重洋,到国外攀亲结友,深受各国人民的欢迎。大熊猫身体胖软,头圆颈粗,耳小尾短,四肢粗壮,身长约1.5米,肩高60-70厘米左右,体重可达100-180千克。特别是那一对八字形黑眼圈,犹如戴着一副墨镜,非常惹人喜爱。 大熊猫的祖先是食肉动物,现在却偏爱吃素,主要以吃箭竹为生。
一只成年的大熊猫每天要吃20千克左右的鲜竹。有时,它也会开一次“荤”,捕抓箭竹林里的竹鼠美餐一顿,甚至大摇大摆闯入居民住宅,偷吃食物。大熊猫性情孤僻,喜欢独居,昼伏夜出,没有固定的居住地点,常常随季节的变化而搬家。春天一般待在海拔3000米以上的高山竹林里,夏天迁到竹枝鲜嫩的阴坡处,秋天搬到2500米左右的温暖的向阳山坡上,准备度过漫长的冬天。
每年的四五月份是大熊猫的繁殖季节,雄、雌大熊猫难得同居在一起。但5月一过,便又各奔东西。雌性大熊猫怀孕4-5个月左右,就急着寻找树洞或石穴作为“产房”,它每胎产1-2仔。刚生下的幼仔重量只有150克左右,相当于妈妈体重的1‰。
可是,一个月后体重可达2千克,3个月就能长到五六千克。熊猫妈妈常把小熊猫搂在怀中,轻轻抚摸,外出时也把它衔在嘴里,或用背驮着,亲亲热热,形影不离。等到小熊猫五六个月大时,妈妈就开始教它爬树、游泳、洗澡和剥食竹子等本领。两年后,小熊猫才离开母亲,开始独立的生活。大熊猫的寿命一般为20-30年。 大熊猫的家族非常古老。
大约在一百万年前,它们遍布我国的陕西、山西和北京等地区,在云南、四川、浙江、福建、台湾等省也有它们的踪迹,现在留下来的数量很少,成为科学家研究生物进化的珍贵的“活化石”。 迄今为止,全世界200多个国家和地区都没有几乎濒临绝迹的大熊猫,只有在我国的四川、陕西、甘肃部份地区的深山老林中才能找到它们的身影。
目前全世界的大熊猫总数仅1000只以下,而且数量在不断减少。 根据科学统计有78%的雌性大熊猫不孕,有90%的雄性大熊猫不育,这就给大熊猫的繁殖带来了许多困难。 在动物学上,大熊猫属食肉目。据考证,大熊猫的古代名称有貘、白豹、虞等。在200多万年前的更生世早期到100万年前的更生世中晚期,大熊猫已经广布于我国南半部,组成了大熊猫----剑齿象动物群;今天该动物群的许多种已经绝灭,而大熊猫却一直活下来,所以大熊猫有“活化石”之称。

+ 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.

It is one of the most precious animals. Their bodies are very long, about one zhang(丈). Dolphins live in the sea. They live on fish, shrimps and so on.
Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!
Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.
Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.

+ 加入清单Advice on Protecting Wild Animal
Many animals are in danger of dying out。 As is shown in the chart, we can see the number of animal species decreases faster and faster and this trend will continue。 From 1980 to 2010, at least 1 million animal species have disappeared。 Worse still, more and more wild animals are in great danger。 It is not a piece of sensational news; it is a fact, a harsh reality。 Unfortunately, we may not see these animals in the near future。
很多动物频临灭绝的危险。图表显示,我们能够看到动物物种数量下降的速度越来越快,而且这种趋势将会持续下去。从1980年到2010年,至少有100万动物物种已经消失。更糟糕的是,越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻,这是一个事实,一个残酷的事实。不幸的是,将来我们可能看不到这些动物了。
From the second picture, we can find some reasons。 Why is the number of animal species declining year by year? Apparently animals have bee victims of fashion industry。 Animal skin has been used to make fashionable clothes and these clothes sell at a high price。 So some greedy people begin to kill animals in a large quantity。 This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings。
从第二幅图我们能够找到一些原因。为什么动物物种的数量一年年的减少呢?显然,动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服,而且这些衣服都是高价出售。因此,一些贪婪的人就开始超多屠杀动物。这种不负职责的行为不仅仅打破了自然的平衡,而且使人类居住环境陷入危险。
As far as I am concerned, something must be done to stop this illegal action。 We believe "no buying, no killing"。 First, we must make concerning laws to protect these animals in danger。 Second, we must take some measures to protect animals effectively。 Animals are our friends and part of our environment。 Third, we should raise peoples awareness to protect animals and our environment。 In this way, we can build a harmonious society and ensure a sustainable development。
在我看来,我们务必要做些什么来阻止这种违法行为。我相信“没有买,就没有杀”。首先,我们务必制定有关法律来保护这些处于危险中的动物。其次,我们务必采取一些措施有效的保护动物。动物是人类的朋友,也是我们环境的一部分。再次,我们就应提高人们保护动物和环境的意识。这样一来,我们就能够建立一个和谐的社会,确保其可持续发展。
