Animals are friends of human beings. An animal is dependent on the human, also, the human also cannot leave the animals.

Long, long ago, animals and humans are a good friend. They help each other, rely on each other, get along with, who also cannot leave the who. However, with the passage of time, because of human beings, the animals with human relations soured, and there are more and more serious trend.

First of all, human beings to animals is wanton killing, on the one hand, caused a substantial reduction in animals, on the other hand also caused the animals to human hostile, to some extent destroy the animals with human friendly relationship. In fact, for a long time, the behavior of the human animal cruelty has not rested, eat eat peacock, owls, monkey, red-crowned cranes, bear bile absorption, is really to the point of "all things" entrance! What do you want to, so can not cause animal angry? How can you make animals not to stand up and fought back? This is also the animal attack humans, even damage the important reason of human life.

Second, with the progress of human society, some bad behaviors of human beings, not only destroyed the earths environment, and damage to the animals living environment. Factory sewage, automobile exhaust, deforestation of forests and other bad behavior, have caused serious damage to nature, and at the same time there are opposite to the nature of the direct damage caused by animals that makes the animal difficult to live, the type and quantity less and less, destroy the balance of the ecosystem, eventually make human to destruction.

Visible, the relationship between animals and humans have come to the point where serious deterioration, at the same time, also pose a threat to the survival of mankind itself. Humans are still can such wrong-headed, impenitence? ! I think that human beings should be timely change their bad habits, to love animals, protect earths environment.

As a primary school student, we should start from me, start from now, to take care of our nature, protect the animals around us.

Let us act together, take care of animals, people for the ethical treatment of animals, and become a good friend of animals, to improve the relationship between the animals and humans to make their due contribution!

动物是人类的朋友。动物离不开人类，同样，人类也离不开动物。

很久很久以前，动物和人类是一对好朋友。他们互相帮助、互相依靠、和睦相处，谁也离不开谁。但是，随着时间的推移，由于人类自身的原因，造成了动物与人类的关系恶化，而且有越来越严重的趋势。

首先，人类对动物的肆意捕杀，一方面造成了动物的大量减少，另一方面也造成了动物对人类的敌意不断增强，一定程度上破坏了动物与人类的友好关系。事实上，一直以来，人类残害动物的行为一直没有停息过，吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆，真是到了“万物皆入口”的地步!您想，这样怎么能不引起动物的愤怒呢?怎么能让动物不挺身而出、奋起反击呢?这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。

其次，随着人类社会的不断进步，人类自身的一些不良行为，不仅破坏了地球环境，也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为，都对大自然造成了严重的破坏，同时也对生存在大自然的动物造成了直接的伤害，使动物生存艰难，种类、数量越来越少，破坏了整个生态系统的平衡，最终使人类走向灭亡。

可见，动物与人类的关系已经到了严重恶化的地步，同时，也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗?!我想，人类应该及时改变自身的不良习惯，爱护动物，保护地球环境。

作为一名小学生，我们应该从我做起，从现在做起，爱护我们的大自然，保护我们周围的动物。

让我们大家一起行动起来，爱护动物，善待动物，成为动物的好朋友，为改善动物与人类的关系做出自己应有的贡献吧!

Last week, I visited the geological museum with my best friend, Liu Bing.

It was my first time to go there. The moment we arrived there, we found that the

building was grand. When we walked into it, there was a big hall in front of us.

And then there were several rooms to show different kinds objects. There was a

room for collecting scripts and paintings. There was another room to store

clothes and shoes in the old times. The next room was for collecting the daily

necessities in the old days. In a word, all the things in it had a long history.

I learnt some knowledge from it.

Green, the color of life; The color of green, environmental protection; With green have the fresh air; With green have the ooze of flowers; Green and healthy life.

Low carbon, environmental protection is refers to life work and rest of the energy consumption to reduce as far as possible, so as to reduce emissions of carbon dioxide. In our ordinary people low carbon is a kind of attitude, we should pay attention to the saving, fuel-efficient, solar terms, from the start bit by bit.

Over the years, with the deepening of industrialization, a large amount of carbon dioxide discharge, make the global temperature rise, climate change, it is indisputable fact. The world meteorological organization reported: nearly 10 years of 10 years is global warmest on record. In addition, global warming also makes the Antarctic ice began to melt, causing sea levels to rise, the use area of narrow, humans cannot survive, massive death of animals and plants.

Each piece of articles for daily use, big to small home appliances to toys, books and decoration, each items of the production cost of resources and energy, will bring carbon emissions, perhaps you abandoned things may be needed by others, no longer buy new articles for daily use, will naturally reduce the resources and energy, reducing carbon emissions.

The classmates, in order to "green" of the world, let us act, to cherish green, take good care of green, to create green give an own strength.

绿，生命的颜色;绿，环保的颜色;有了绿色便有了清新的空气;有了绿色便有了沁鼻的花香;有了绿色便有了健康的生命。

低碳环保就是指生活，作息的所耗用能量尽量减少，从而使二氧化碳的排放量减少。于我们普通人来说低碳是一种态度，我们应该时候注意节约、节油、节气，从一点一滴做起。

多年来，随着工业化的深入，大量二氧化碳的排出，使全球气温升高，气候发生变化，这已是不争的事实。世界气象组织曾公布：近10年是记录以来全球最热的10年。此外全球变暖也使得南极冰川开始融化，进而导致海平面升高，使用面积缩小，人类无法生存，动植物大量死亡。

每一件生活用品，大至家电小到玩具，书籍和摆设，每一件物品的生产都要耗费资源和能量，都会带来碳排放，或许你废弃的东西也许正要其他人所需要的，不再购买新的生活用品，自然会降低资源和能源，减少碳的排放量。

同学们，为了世界的“绿色”，让我们行动起来，为珍惜绿色，爱护绿色，创造绿色献出自己的一份力量。

The monkey also called marmosets, and its name, the aye-aye only roughly the size of a finger. Refers to the monkey around 10-12 cm tall, weighs about 80-80 grams. The largest but also 35 centimeters. Its tail is long and fluffy, generally up to 20-35 cm, like a small broom.

Monkeys like to live in the rainforest, hiding in the nest to sleep during the day and night activities alone or in pairs. So how the aye-aye foraging? At night, with the frequent "alas alas," cries, secretive refers to the monkey out, hunting tree of worm is refers to the monkey handy trick, start, walking along the trunk, gently tip close to the bark, when they hear or smell anything, then stop and sparkling view, which in turn was violently dig bite bark, with his unique fingers dig eggs in the trunk, until to dig out the hidden grubs, and then, out of his fingers, fill in the entry grubs squashed. The aye-aye mainly in a variety of fruits, nuts and insects. Due to monkey likes to eat eggs on the bark or dead, larvae, and small beetles, its eating habits, much like the trees doctors - woodpecker, so have the effect of the woodpecker. So close to the island of Madagascar on the African continent have a woodpecker, here was replaced by a monkey.

Mother marmoset pregnancy for 140 ~ 150 days, every child 1 ~ 3. Marmosets family, male marmosets plays the role of "good husband good father". Female marmosets, after giving birth to children only embrace when feeding them for a while and take care of children work all fell upon the male marmosets. Males marmosets as little marmoset clean themselves, by the time the little marmoset no longer eat milk, it will be personally feeding the kids eat

Now marmoset habitat reduction, degradation and human hunting is the main factor to the dangerous animals. Because the monkey evolution so far still with original appearance and characteristics of life, so is very scarce. Marmosets throughout the monkeys in the family, only a dozen in all over the world. Many Malagasy believe that monkeys will bring them bad luck. If you see a refers to the monkey, they will kill it at once. On the other hand, refers to the monkeys live in the rainforest has been cut down, so they also face the danger of extinction. Let us act together, to protect endangered animals.

指猴又叫绒猴，和它的名字一样，指猴只有人的一根手指差不多大小。指猴的身高10—12厘米左右，重约80—100克。最大的也不过35厘米左右。它尾巴又长又蓬松，一般可达20—35厘米，就像一把小扫帚。

指猴喜欢栖息在雨林中，白天藏身于巢窝中睡觉，夜间单独或成对出来活动。那么指猴又是如何觅食的呢?入夜了，随着一声声“唉唉”的叫声，诡秘的指猴出动了，猎取树缝中的小虫是指猴得心应手的把戏，开始，轻轻沿着树干行走，鼻尖紧贴树皮，当听到或嗅到什么，便停下来凝神观看，继而便猛烈地掘咬树皮，用它特有的手指抠树干中的虫卵，直到挖出隐藏着的蛴螬，然后，伸出指头，把蛴螬压扁填入口中。指猴主要以各种水果、坚果和昆虫为食。由于指猴最喜欢吃树皮下或枯树上虫卵，幼虫，小甲虫，它的进食习性，颇像树木医生--啄木鸟，因此起到了啄木鸟的作用。所以在离马达加斯加岛很近的非洲大陆有啄木鸟，这里则被指猴所代替了。

母绒猴孕期为140～150天左右，每胎1～3仔。狨猴家族里，雄狨猴充当着“贤夫良父”的角色。雌狨猴生下子女后，只在喂奶时抱上它们一小会儿，照料孩子的工作全落在雄狨猴身上。雄狨猴会为小狨猴清洗身体，等到小狨猴不再吃奶时，它还会亲自喂小家伙们进食

现在绒猴栖息环境的缩小、恶化和人为的捕猎是使这种动物致危的主要因素。由于此种猴类进化至此仍然带有原始的面貌及生活特征，所以极为稀缺。狨猴在整个猴类家族中，在全世界范围中仅仅只有十几种。许多马达加斯加人认为指猴会给他们带来恶运。如果看到一只指猴，他们会立刻把它杀死。另外，指猴赖以生存的雨林遭到了砍伐，所以它们也面临着灭绝的危险。让我们一起行动起来,保护濒危动物!

I am a student in Huaxing Middle School. Do you know the plastic bags? Do you often use the plastic bags? I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose(分解) in a short time. The plastic bags will make our world worse. I agree with the rule, which people can’t get the free plastic bags in the shops, supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.

So I hope all the students in our class stop to use the plastic bags, and use our own cloth bags. I hope we can take care of our environment.

Let’s make our world more and more beautiful.

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。

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。

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。

上午，平平想养青蛙，于是，他拿了网和水桶出发了。

平平捉完青蛙，回家了，把小水桶放在桌上了。第二天平平要看看青蛙。青蛙没什么同样，只好听录音机。录音机里说了“请保护青蛙”平平不明白，就到书房里找书，他找到一本《动物百科知识》书，书里写着“青蛙是有益的动物”，我们要保护它。青蛙专门吃田里的害虫，是保卫田野的卫士。

平平知道自己做错了，便脸红了，他回到了池塘边把青蛙放了，一边对青蛙说：“小青蛙快回家吧！”

小朋友，我们要向平平学习，要保护小动物。

Water is the source of life. Human can not do without water, animals, plants cannot survive without water. We every day to drink water, water, not only we need water, the fish in the water, the crops of the fields, the trees on the hill, and so on all need water. Some people may think so: water is to burn forever, love how how waste waste, this idea is wrong, we should change the idea.

I listen to mama said, in our city the creek, at the time of their small river on the bottom, they often catch fish in the river, catch shrimp, game play, but now is full of rubbish, into a dry river.

水是生命的源泉。人类离不开水，动物、植物也离不开水。我们每天要喝水、用水，不光我们需要水，水里的鱼儿、田里的庄稼、山上的树木等等都需要水。有的人可能这么想：水是永远用不完，爱怎么浪费就怎么浪费，这种想法是不对的，我们应该改变这种想法。

我听妈妈说，在我们城里的这条小河，在她们小的时候河里清澈见底，她们经常在河水里捉鱼、捉虾、游戏玩耍，可是到了现在却到处是垃圾，成了一条干枯的小河。

水与我们每一个人都关系密切，如果没有水，农作物就无法生长，我们就没有吃的粮食和蔬菜了，我们每天洗手、洗菜、洗衣…一刻也离不开水。如果没有水，我们就不能生存。既然水的作用那么大，我们就应该节约用水，从小养成节约用水的好习惯，做到人走关好水龙头、不把垃圾扔到河里…使水能够保持干净。

为了我们大家有一个良好的生活环境，让我们一起携手起来，从我做起，从现在做起，树立起节水、护水的观念，爱护水就是爱护我们自己。

为了我们美好的未来，我们大家一起努力吧!

Recently, a large number of affairs about sexual assault were disclosed and reported by mass media. As far as I am concerned, people should get some enlightenment from these affairs, such as enhancing and strengthening education inSelf-protection awareness, especially for children and students.

最近，有很多关于的事件媒体揭露和报道。我认为人们应该从这些事件中得到一些启示，比如，提高和加强自我保护意识教育，特别是对于儿童和学生。

Children and students are hurt most in this kind of affairs. As a result, to enhance and strengthen their self-protection awareness is indispensable. In addition, to strengthen the awareness of defending danger is also important. If they can realize the potential danger from someone or something before it happens, they can make some preparations to avoid the danger and reduce the rate of being hurt.

因这类事件伤害最大的是儿童和学生。因此，提高和加强自我保护意识是必须的。此外，加强防范危险的意识也是很重要的。如果他们能在事情发生前意识到某人或某事的潜在危险，他们就可以做一些准备来以避免和减少受伤率。

Therefore, I advocate that parents should help their children develop self-protection awareness from birth, such as designing some situation for them to cope with. In addition, parents should teach their children to recognize the danger and how to avoid and reduce the danger from outside. Besides, children also need to develop an excellent ability of observation.

因此，我认为父母应该帮助他们的孩子从出生开始就培养自我保护意识，比如，设计一些情况来让他们应付。父母还应该教导孩子认识危险，如何避免和减少来自外界的危险。此外，孩子也需要培养优秀的观察能力。

In a word, to protect children needs both the effort of parents and children themselves.

总之，保护儿童需要家长和孩子他们自己的努力。

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.

It is well known that trees can absorb carbon dioxide, emit oxygen, purify the air, and are the necessary conditions for our human survival. But some people for the money to deforest trees, resulting in excessive soil erosion, the earths vegetation has been severely damaged, oasis and the city is also desertification, our human survival has been threatened. We usually use a one-time chopsticks, every day to spend dozens of acres of forest, in those eyes, trees can be made in addition to furniture and building materials, it seems that there is no value. Is there someone who does not understand what trees mean to us? Our living area is already very small, and if you go on like this, it may be that our only land is lost.
