The pandas like eating bamboo. Using the paws,he chew the bamboo very slowly with his mouth.

There are two pandas called tuantuan and yuanyuan will send to Taiwan.

The doctor shook his head, said: "because there are too many viruses in the air, is full of garbage, house dust, industrial emissions, and so on, these are the cause of poor air quality, virus." I seemed to understand a lot.

With the development of the society, living standards continue to improve, we drink the tap water, use the TV set, refrigerator, heater, elevators, etc. But in life, we constantly in the waste of resources, clean water, watering the flowers in the water, washing water, waste every day. Water for us to be of much use, irrigate farmland water, building water, plants and trees need water, and peoples life water for industrial water, we cant live without water. However, as we waste water was contaminated. If we use wash bowl of water to water the flowers and clean the water to wash clothes, wash your hands when the water is boiling down a little, that how much we want to save water.

When we are standing on the street, smell the stench, walking in the street is full of garbage, look up at the sky gray, one after another car emissions both in the exhaust, and people in disorderly cut down trees? Observe, to think of it, our environmental protection consciousness is so bad.

Nature cannot be improved, the life can choose to choose green, environmental protection, everybody is responsible for.

环境保护，人人有责。 我不小心感冒了，不知道是为什么，于是就去看了医生，妈妈问这“是流感吗?”妈妈问。

医生摇了摇头说：“因为空气中有太多的病毒，到处是垃圾，修房子的灰尘，工业排放的废气等，这些都导致空气质量差、病毒多的原因。”我似乎明白了很多。

随着社会的发展，生活水平不断提高，我们喝上了自来水，用上了电视机，冰箱，取暖器，电梯等。但生活中我们不断地在浪费资源：打扫卫生的水，浇花的水，洗衣服的水，每天都在浪费。水对于我们有多大的用处，浇灌农田要用水，修建房屋要用水，花草树木需要水，还有人们的生活用水工业用水等，没有水我们就无法生存。然而水在被我们浪费，被污染。如果我们用洗碗的水来浇花，洗衣服的水来打扫卫生，洗手时水开小一点，那我们要节约多少水。电也一样，我们每天每人少开一盏灯、少看一小时的电视，少座一次电梯，我们要节约多少电。当我们站在街上，闻到的是臭气，走在大街上到处是垃圾，抬头看天空灰蒙蒙一片，一辆接一辆的汽车都在排放着尾气，还有人在乱砍伐树木?注意观察，仔细想想，我们的环保意识实在太差了。

自然不可改良、生活可以选择 选择绿色生活、环境保护，人人有责。

Environmental protection is not a new question for us, our government has put forward clear governance objectives. As every ordinary people in real life, although not may be directly engaged in environmental protection work, but we can starts from the minor matter, starts from me.

When see the bathroom faucet is dripping, close is able to raise your hand? When the battery after use can be classified collection processing and not carelessly throw away? Whether consciously or the use of ultra-thin plastic bags when shopping? Them are very small, but it reflects how much we have environmental protection consciousness.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 big tree. Recycling waste 20 boxes can create a beautiful pen container. Recycling one glass bottle to save energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

环境保护对我们来说并不是一个新问题，我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人，虽然不可能都直接从事环保工作，但我们完全可以从小事做起，从我做起。

当看到洗手间的水龙头在滴水时，是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?一件件小事虽然都很不起眼，但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸，可以挽救17棵大树。回收20个废餐盒可以造出一个漂亮的笔筒。回收一个玻璃瓶节省的能量，可使灯泡亮4个小时。回收1个铝罐就等于节约了半个铝罐的石油。所以我们应将垃圾分类安放，由有关部门回收后再生产再利用!

只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、也为自己留下一片碧水蓝天，我希望人人都能自觉保护环境，让我们的生活环境更加美好。

There are many animals around us, such as: kittens, puppies, birds ... they are all objects of our love.

I keep a lovely puppy, and I call it black. He is my most faithful friend. Every time I came home from school, the dog will squat on the ground to shake my tail, Mimi smile, very cute!

Puppy still have a skill, you know? That is to catch the thief. At night the dog is my home "police". Once the thief into our village, the puppy will issue an alarm to inform all the police officers to catch the thief, to the last thief surrendered, the dog can be on the list.

There are many families in the world, the family kept a cute little animal. They take care of the small animals healthy and healthy, and they are very smart. But some people put the lovely little animals as their own enemies, all day abuse of small animals, the small animals were vicious "law", it is too gas! I hope that in this "big family", everyone can protect every animal here, care about it, love it.

Lets love each other and love every animal here!

世界上有成千上万的野生动物，它们都是我们人类的朋友，我们应该要保护它们，关爱它们，不要伤害它们。我相信我们对它们友好，它们也一样会对我们很友好的。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗 没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗?

比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!

According to my collection to a report said:"the environment problem is due to human is not reasonable to develop and make use of the natural source caused by environmental problems.Red main air pollution,water pollution,noise pollution,food contamination,not suitable development and utilization of natural resources it five categories." As one of the fact that we iron,they are like a demon ruthless swallowed with human life.It threatens the ecological balance,the harm to human health,and restricts the sustainable development of economy and society,it lets the human was in trouble.For this I make declared:"as long as we have not forgotten--human moment of the environmental protection consciousness,have the consciousness of the environment according to law,the global village will be beautiful paradise".The future of the sky of dark blue must be,water is clear,the green flowers,can enjoy the human nature with our happiness.

"The real test our environment is not words,but action contribution." Although I do is just some small things,but I firmly believe that if we all have the responsibility to protect the environment,from oneself,starts from the minor matter,starts to protect our homes,to human nature will be rewarded.In the cradle of warm-a prairie; In the smiling face of the kind-growth,source of love-bathing in the river

据我收集到的一份报告说:“环境问题是由于人类不合理开发和利用自然源所造成的环境问题。红主要空气污染、水污染、噪声污染、食品污染、不适当开发利用自然资源这五大类。“我们铁的事实,他们就像一个魔鬼无情的吞噬着人类的生命。它威胁着生态平衡,危害人类健康、制约经济和社会的可持续发展,它让人类陷入了困境。为此我宣称:“只要我们不忘记,人类的环境保护意识,依法环境的意识,地球村将美丽的天堂”。深蓝色的天空的未来是必须的,水是明确的,绿色的花,可以享受人性与我们的幸福。

“真正的考验我们的环境是没有话说,但是行动贡献。“虽然我做的只是一些小事,但我坚信,如果我们都有责任保护环境,从自己做起,从小事做起,开始保护我们的家园,人类自然会得到回报。在暖和的摇篮草原;kind-growth的笑脸,在河里love-bathing来源

Today, as the development of the technology, people live a much better life than before, the average wage is promoted highly. The economy develops at the cost of polluting the environment, we can see the pollution everywhere, like the river water is dirty, the situation is so serious that we must take some action to control the environmental pollution. First, we should not throw away the rubbish, whenever we have rubbish at hand, we should keep the habit to throw it into the dustbin, sometimes the garbage can be recycled. Second, the government should make some measure to punish the industry which is not deal with the pollution well. With the government’s intervention, the businessmen will pay special attention to the pollution and dare not to ignore it. Protecting the environment needs everyone’s effort, to ourselves and our offspring’s health, we must take action to protect the environment.

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友，人们应该善待它们，但现在，中国和世界上的许多人为赚钱而捕杀动物。众所周知，中国有许多珍稀动物，如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋，或是为了食用它们的肉。

结果大量的珍稀动物死亡了，真可惜呀!

目前，我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们：也捐款来支持保护动物的活动，如，有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物，因为自然就像一个大家庭，人类和动物必须和平共处：我们必须保持生态平稳。

如果人类能这么做，这个世界就会越来越好。

The animal is the friend of our human beings. We live in the same earth. Animals and human beings can’t be separated from each other. But some animals are getting less and less. So it’s necessary for us to protect animals, especially wild animals. Some people kill wild animal because of money. It’s illegal. Beside, because of the development of society, human needs more space to live in, so we explore the forest. Animals have less space to live in. The number of wild animals decreases year by year. It’s high time to take actions to protect wild animals.

动物是人类的朋友，我们共同生活在地球上。动物和人类不可以彼此分离。但有些动物的数量越来越少，所以我们有必要去保护动物，特别是野生动物。一小部分人为了赚钱而去猎杀野生动物，这是违法行为。此外，由于社会的发展，人类需要的生活空间，所以要开发森林。然而动物的生存空间却变少了。野生动物的数量逐年减少，现在该是采取措施保护野生动物的时候了。

保护森林(Protecting the Forests)

Now in some places of our country, a number of people have been cutting down the trees in the forests because they need wood and more farmland. The areas of forests are getting smaller and smaller. Some scientists say that there will be no vast forests in 20 or 30 years. It is really a terrible thing. Where the forests disappear, dust storms will occur occasionally. The weather will get hot and dry. The whole earth will become a big desert. A lot of plants and animals will disappear.Crops will not grow anywhere. Life will be difficult for everyone. The human beings will be punished for their forest-destroying activities.

Therefore, we should realize the importance of taking care of our forests. We should do our best to protect our living environment and keep our mountains green,the water clean, and the sky blue.

保护森林

在我国的一些地区，由于需要木材和得到更多的耕地，许多人一直在砍伐森林中的树木，森林面积正变得越来越小。一些科学家预言二三十年后将不会再有大片的森林，这真的是一件可怕的事情。森林在哪里消失，沙尘暴就在哪里发生，天气会变得炎热而干燥，整个地球会变成一个大沙漠，大量的动植物会消失，没有地方再长庄稼，生活会变得很艰难，人类因为破坏森林的活动将受到惩罚。

因此，我们应该认识到保护森林的重要性，尽最大努力保护我们的生存环境，保持山绿、水清、天蓝。

饕餮，上古传说中的贪吃怪兽。只吃不出，十分贪婪。它用来比喻那些贪婪的人类。而现在的“饕餮”是越来越多了，就是那些见钱眼开，屠杀贩卖甚至大吃特吃野生动物的坏人，他们多是为了自己的利益而用动物来卖钱。

物竞天择，适者生存。这个生物法则是不可能改变的，而人类却利用这个法则，无情地残杀动物们，以达成目的——用动物身上的肉、皮毛来卖钱。

生态平衡，缺一不可。一种生物的灭绝，可能就是一条生物链的消失。而现在因为人类的破坏，有许多物种已经灭绝或者是差一点儿就灭绝灭亡了。

就举长江江豚的例子来说吧。江豚是国家一级保护动物。可是因为有人喜欢吃，还是有人挺而走险，捉来长江江豚来卖，导致现在长江江豚的数量只有大约1000条左右了。没有买卖就没有杀害，没有吃货就没有杀戮。

在美国，曾有一个餐馆，为了吸引客人，抓了一只猛兽狗熊来吸引客人。客人多起来了，餐馆老板却不给猛兽吃的。狗熊已经饿得皮包骨头了。后来因有人举报，老板被抓走了。

电捕鱼、大网捕鸟、猎枪击射……人们为了赚钱，不择手段的追害动物们。甚至有人为了让皮色更好一点，能多赚点儿钱，甚至，在动物活着的时候，扒下它们的皮毛。太残忍了啊！

濒危动物的在劫难逃，全球保护刻不容缓，现在各个国家几乎都有了保护动物的法律。还有一些明星做公益广告，让人们不要再穿着动物皮毛们做的东西了。抵制皮草制品，从我的父母家人做起。

如果地球上没有了动物，人类会怎样？降临在动物身上的命运，终究会降临在人类的身上。为了我们的子孙后代，更为了未来和谐多元化的地球，让大家都行动起来保护它们吧！

Today, Chinas economy has made the great achievement. More and more

foreign people come to China to seek for cooperation. It is true that peoples

life standard has been improved a lot during the last decades, but the

environment has been polluted badly. When I was very small, I could see the

green trees and clean water around my hometown, but now, the river becomes

smaller and the rubbish can be seen everywhere. I feel so sad about it. We have

Schoolmates, when we light this pile of paper, our hands shake, and through the light of the fire, we see a piece of green wood.

How should we protect the environment?

First, love nature and be the little leader and little propagandist who protects nature. We should love the grass and trees of the campus and the streets, and strive to be the guardians of the garden. We should not only understand the natural balance of nature. We should also promote the environmental protection of natural environment to students, society and families.

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.

水很有用，我们每天喝水，用水洗东西。在许多地方没有很多水，我们不应该浪费水，我们应该再利用水并节约用水。

不仅水要节约其他能源也要节约。我们所用的绝大部分能源来自煤炭和石油。地球上没有很多煤炭和石油。我们应该节约能源。我们不应该开车太多，因为汽车要使用许多能源。

科技的发达，使得地球上的绿色越来越少，所以我们不能砍伐太多的树。因为木材来自于树木，我们用木材来制作桌子，椅子和其他许多东西。并且树木还可以净化空气，美化环境。

地球上的白色污染也越来越严重。我们使用塑料来制作袋子和瓶子，但太多的塑料对地球有害。我们不应该使用太多的塑料袋和塑料瓶。我们应该使用纸袋和玻璃瓶。

好了，说了这么多，地球的未来还是要靠我们行动的!
