为什么我们应该保护野生动物英语作文初二(最新20篇)

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

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.

Students, we hope that the motherland can become pure and quiet sunshine, fresh air, such a beautiful and desirable country. How we need such air, how much we love the environment! However, boys and girls, do you know that we live on earth, good environment is destroyed, the forest on the decrease, soil and water erosion, rivers in become turbid, desert in the extension, noise increased, the population growth and the air is polluted, many share the rare animals are endangered because of this, all this will bring us endless disaster.

As a new generation of Chinese people, we should always cultivate environmental awareness and worry about our country. Some students, however, do not cherish the paper, only to tear up several sheets of paper at the beginning of a composition. Trash and see if there is an opportunity to the school, where two-thirds of all kinds of waste paper, in order to make the paper, we paid a heavy price, consumes large forests. 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.

Secondly, starting from me, from now on, protect the surrounding sanitation. Do not spit, pick flowers, do not destroy trees, forests, waste paper, etc. Although our strength is limited, if everyone can start from me and start from now, then our environment can be improved.

Thirdly, we should study the knowledge of culture and science carefully, and make a great effort to protect nature from m. We in the primary school to learn scientific and cultural knowledge, grow up, with our wisdom and hands control waste water, waste gas, waste residue, mountains and desert to governance, to improve soil and water quality. I believe that our home will be better in that time.

Students, for the better of our homeland, make a move!

At present,the endangered animals are increasingly fast.How to protect them become our priority.People are crazy about killing animals for their meat, fur.But it is wrong because that animals are our friends, we should try to protect them,instead of killing them to die out. Pandas are represents of endangered animals, which live in the forest and live on bamboos for food. They only depend on the nature reserves to live.

今天，妈妈从外边回来时，一进门就对我说：“你猜，我给你带来了什么?”我说：“鸡翅?”妈妈摇摇头说：“不对，再猜。”我说：“书!”妈妈很兴奋：“你怎么知道?”我笑了笑，伸手接过妈妈递过来的书——《魔法手指》，是罗尔德。达尔的书。我一直都很喜欢罗尔德。达尔的收。太有趣了，怎么是魔法手指呢?手指怎么会有魔法呢?于是，我拿迫不及待地拿起书看了起来。

不一会儿，我就把这本收看了完了。这本书太有意思了，太神奇了。文中的小女孩有一种与生俱有的本领，在怒不可遏时，她的手指就会施出魔法来。她的邻居革利鸽夫妇一家爱好打猎。有一次，当小女孩看到她们又去打野鸭子时，她生气了，她怒不可遏，她的手指又施出魔法了，把革利鸽夫妇一家变成会飞的野鸭子，把野鸭子变成了人。这样，革利鸽夫妇一家就只有到树上搭窝、睡觉，饿了就吃树上的苹果，而野鸭子却占有了他们的家。野鸭子拿着枪要打革利鸽夫妇一家，革利鸽夫妇一家吓坏了，当野鸭子准备开枪时，革利鸽夫妇一家说：“我们以后再也不打猎了。”之后，魔法消失了，革利鸽夫妇一家又变回了人样，从此以后，他们改名叫“爱鸽先生”、“爱鸽夫人”，再也不打猎了。这个故事真是太有趣了，这个魔法太有趣了，它可以让打猎者和被猎者彻底掉了个儿。达尔的奇思妙想让人坊起来真是忍俊不禁。

读了这个故事，我明白了：我们不能伤害动物，相反地，我们要很好地保护好对人类有益的动物，因为动物是人类的朋友。只有这样，我们的地球才会越来越可爱，我们的家园才会越来越美丽，我们才能生活得越来越幸福!

生命的长度，也许是由几百年，也许是由短短的几天，也有可能连出生都没有，就已经一命呜呼了，生命又是谁能够决定的呢？是谁能决定不让意外、生病… …等危害生命的事情发生呢？种种原因，谁能不面临死亡？现在只能珍惜生命，以及避免发生不好的事。

很多人说要珍惜、保护、尊重生命，但是人人都有做到吗？自认为不自杀、不发生意外，不生病就叫做完全做到，大错特错了!除了自己，还有别人，除了人，还有动物，都应该要被保护、珍惜、尊重。我们如何做，才可以做到呢？弃养狗的问题很严重，所以我们不养狗，就是最正确的事情。

狗就是人的朋友，怎么对待好朋友，就该怎么对待它们，而不是当作驱赶坏人的好工具，或是一只很可爱的会动娃娃。狗虽然不会讲人话，但它会中心不二的在你身边，想到弃养它们的人，是不是很可恶？你在养之前，确定等待他长大之后，还是会继续养，不看外表？你确定有能力吗？还是只是为了看门而已？养它们之前，请三思!养了之后，它也许和它的家人分开了，就只有你唯一一个家人，所以必须也把它当家人，如果你变成狗， 就一定明白，这多么无助，多希望有人爱。

当你弃养狗，接下来的事情，我相信每个人都无法接受，它又失去家人了!它将被送至收养中心，没人喜欢的话，就要安乐死，如果你失去家人，没多久又莫名被关起来坐牢，几天之后，没人想接你回家，你就要面临死亡，发生这种事情，你又不能决定，死的很奇怪吧!对，这是弃养狗的人，做的事情，换做是你，你会无法形 容这种感觉，别人说不公平，其实我们都很幸福，爸妈不会不要我们，它们才觉得不公平吧？为什么是别人选自己，而不是自己选别人，为什么说不养就可能死？狗对人们就是不平等。

我们不该做这些弃养的事情，是谁都不愿意被抛弃，要养宠物，就要好好爱它，不只狗，任何动物都一样，爱它就不要丢弃它，人人有责，大家一起保护生命，才是护生的真正意思!

Trees on the hills have been cut do n,and aste ater is being poured continuously into rivers. Furthermore, herever e go today, e can find rubbish carelessly disposed. The hole 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, ne la s must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures ill be effective and bring back a healthful environment.

全世界的环境问题变得越来越严重。例如汽车污染的空气影响了人们的呼吸，工厂释放污染的气体，山上的树木被砍伐，污水不断被排人河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。事实上，污染正威胁我们的生存。

地球是我们的家园，我们有责任为我们自己和我们的后代去照顾好它。庆幸的是，愈来愈多的人们已经意识到这些问题。政府已经采取了很多措施去解决这些问题，法律已被通过以制止污染。我希望这些问题在不远的将来能得到解决，我们的家园变得越来越好。

全世界的环境问题在变得越来越严重。随着工农业的发展，汽车制造噪音、排放毒气，山上的树木被砍伐，污水不断被排入河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变，环境的巨大破坏已带来负面影响，甚至对人类生存带来巨大威胁。

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。

在当今现代生活中，人类是世界的佼佼者，而动物对某些人来说只是一些不起眼的附加品，他们想怎么伤害它们就怎么伤害它们，想怎么虐待就怎么虐待，比如说前几天发生的伤害动物的行为，56只珍稀动物在外有的被杀，有的被捉。就是因为它们既不会叫疼，又不会喊冤。现在尽管这种思想不是每个人都会有，但虐待小动物的现象却时有发生。而你知道么，人类的祖先就是从这些毫不起眼的小动物演变来的。因此我们原本和这些小动物们是一家，一家人就应该其乐融融，互相帮助，帮助那些在外流浪的小猫小狗。既然这样那我们又何必自相残杀呢！动物是人类的好朋友，我们为什么要伤害它呢？就拿下面这件事来说吧！

在一个风和日丽的午后，我和洋洋还有几位好朋友一起去老林子里探险，一到那里就在一座山洞里发现了一只被被褥包裹起来的一个像娃娃一样的东西，叫大人过来一看，哇！是一只已经面目全非的小狗，白色的绒毛下有几道深深的疤痕，好像是被人殴打过一样，拿鞭子抽过，脖子上还有一道肋痕。狗毛零零散散的铺在草坪上，看着特别让人心痛。

回家后，我想了很多：有些人只会当打着保护动物的招牌的冷面杀手，他们不会站在小动物的立场上来想，只会顾自己的快乐，把自己的快乐建立在别人的痛苦之上，这几年有人大肆捕捞鲨鱼，只为一碗昂贵的鱼翅汤和一件鲨鱼皮泳衣。只要自己快乐，别的一切事情好像都与自己无关。小动物也是有生命的，别看那些海洋和陆地杀手，它和人一样都需要得到关爱。如果地球上没有动物，那将会是一个没有活力的世界。就好比我们只能看到一望无际的蓝天，而看不到空中形态各异的白云一样乏味。所以让我们都来保护动物吧，这样我们的家园才会变得更美好！

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. Also, our mother river - the Yellow River in recent years, the river bed and the increasing amount of sediment, becoming the countrys most serious pollution of several rivers. We can not watch the Yellow River from our hands exhausted, so there are many environmental scholars have studied the treatment of the Yellow River pollution program, trying to improve the water quality of the Yellow River. But without our common participation, the cradle of our life - the Yellow River will go to failure and death.

If we are unbridled to destroy the environment, nature will give us punishment. Those large floods deprived of the lives of many people, and because of the greenhouse effect, the Antarctic Arctic glaciers melt the water level, the sea flooded the coastal areas, the economic losses.

My hometown of Guangning is relying on bamboo sea eco-tourism to develop the economy, and now, some bamboo forest environment disorganized, people complain incessantly. Bamboo sea ecological tour is the root of our development of Guangning, if the root was destroyed, how can grow lush foliage, out of the beautiful flowers

Let us be kind to mankind and be kind to nature! I wonder if you have seen "100 things to protect the environment" this article. In fact, we can do a lot of things. Conservation of wild animals, is the ecological balance; treasure water resources, do not dump the garbage to the river; when the environmental guards, the use of each green anniversary publicity environmental awareness, so that the Castle Peak, the United States, the United States, the United States, Often, green water flow, soil fragrance ... ... this is what we can do, why do we not want to practice it?

Now, the earths ecological environment intensified, environmental protection alarm clock has been sounded. Let us join the ranks of the protection of the environment, the creation of a harmonious coexistence between man and nature of the future, so that human beings and nature endlessly reproduce it.

这天，萨娜打着伞和小伙伴们玩耍，一堆东西从天而降，它赶紧撑起伞，可没想到的是，刚买的新伞竟然被砸了几个洞，萨娜一看尽是些破瓶子、滑冰鞋、骨头等杂物，它哭着跑回了家，非常伤心，还在心疼那把漂亮的伞，同时也在气愤地想：为什么人类总是把垃圾扔进海中呢?难道他们把大海当做垃圾场吗?

过了几天，妈妈让萨娜去买食用盐，萨娜刚出门，就有一股刺鼻的味道直往鼻子里钻，而且它看不清前面的路，海水非常浑浊，它捂着鼻子往家跑，不时感觉肚子痛、头晕，妈妈告诉它：

这是因为油轮的石油漏到海里，污染了海水，你可要小心啊!

第二天早上，萨娜和妈妈带着口罩来到了伙伴家，在一起讨论解决环境问题的办法，大家积极思考，最后决定做一些提示板立在沙滩上。

在夜深人静的夜晚，成群的鱼儿们游出水面，在海滩上引人注目的地方立了十几个提示板，希望能够起到作用，大家都焦急地期盼着海洋明天的变化。

第二天，人们看见了提示板，上面写道：

来到这里游玩的人们，请你们不要再往海中扔杂物，我们的孩子因此而受伤，你们也有孩子，希望你们能将心比心，爱护我们这些海洋中的动物吧!我们会成为好朋友的!

大家感到后悔莫及，开始自我反醒，从此没有人再往海洋中乱扔垃圾，鱼儿们又恢复了平静的生活

这些可爱的鱼儿们带给我们深刻的思考：人们在污染环境的同时，不但对自己不利，而且动物的健康和生命也受到了威胁，我倡议大家要提高保护环境的意识，废品应该扔到指定地点，回收再利用。

让我们以身作则，从我做起，共同保护环境，爱护动物吧!

从古自今，世界上的动物种类非常多，但绝种的动物也不计其数。根据生物学家估计，经几千年来，被人类杀害导致绝种的动物，至少有数百种以上。如此一来，世界上的动物就会越来越少了，如果我们在不及时挽救的话，那么将来世界上的动物，可能就只剩下人类了。

大自然是悠久的，富饶的，它拥有的野生动物，是留给人类的无价之宝，如何安抚饱受欺凌的野生动物，就是我们保护动物的基本观念。对动物而言，滥杀是最可怕的行为，然而他们所面对的大敌---猎人，却为了满足自己的口福之欲，或是为了换取钱财，而对他们大肆捕杀。估计在过去的五年之内，有两万只东非的猫科动物被捕杀。每制成一件薄皮大衣就需要十二张动物的毛皮，这些毛皮大衣真是供不应求，价格也非常昂贵。因此必须严禁盗猎者滥杀，违者可以用罚款和判刑来处置。我们身边也有不少虐待动物的例子;班上有些同学会掏鸟窝、杀青蛙，还把小蛇带到学校，吓得一些女生一边尖叫一边用手捂着脸。还有些男生把小蛇杀死后用绳子扣住它尾巴到处吓人。

在动物园里，有些人会经常喂动物吃东西，有些动物不知道怎么吃，往往连塑料袋也了下去，这样一来，再多的动物也会被这种举动折磨死.饲养员们应该多教些喂养知识。这也是爱护动物的有效办法之一。总之，现在我们必须积极保护动物，以免再有动物绝种。试想;如果我们的子孙不能见到大自然的宝贵珍品，那将会是多么遗憾哪!所以保护动物的政策要坚决实施，使野生动物不再灭绝，甚至培植一些新的种类，使我们的子孙也能在观看动物时，享受到我们曾有过的乐趣。

保护动物从我做起!从现在做起!

“大哥哥，你在干嘛呢?”一天下午，在我们住的楼下，我看见一个大哥哥拿着如把扫帚，在空中挥来舞去，不禁好奇地问道。可是这个大哥哥对我毫不理睬，自顾自地继续在空中挥舞扫帚。我有些无趣，又不愿意走开，就静静地坐在一旁观察。仔细看去，我发现原来在空中飞舞着一群蜻蜓。这才恍然大悟，原来他是在捉蜻蜓啊!

忽然，大哥哥兴奋地喊了起来：“抓住了，抓住了!”可是到跟前一看，地上有一只蜻蜓一动也不动，好像死了一样。他觉得很失望，上去就想一脚踩死它。我急忙冲了上去，大声地说：“你不要，给我吧!”大哥哥也不稀罕，没说什么，自顾自地走开了。

我小心翼翼地捧起了这只蜻蜓，放在手心里，心疼地看着它。它该有多疼啊?它妈妈该多着急啊?

我想拯救这只小蜻蜓，就让它在我手心里静静地休息了一会儿。我发现，它在挣扎着想扑腾翅膀，于是，我轻轻地把它抛到空中。让我惊奇的是，它居然能飞起来，只是飞得很低，飞得不远，很快就掉在地上。我跑步上前，再次轻轻捧起它，小心地呵护它，再次送它起飞。

就这样，一次，两次，三次……一次次的失败，我们都没有放弃。终于在第八次，小蜻蜓飞起来了，飞得高高的，飞得远远的。我目送着它渐渐远去，心里别提多高兴了。

在这之后的日子里，每当我走在路上，看到空中飞舞的蜻蜓，我总觉得，其中有一只，不，好像好几只，都在向我打招呼。我想，也许，我拯救的那一只就在里面，在它周围的，是它的爸爸妈妈、兄弟姐妹……

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

Everybody needs themotivationto move on, so no matter what kind of difficulties they meet, they can see the hope and stick to the targets. I have set up small targets for myself, so I can make progress step by step. For example, when I jog on the playground for 800 meters, I will finish every 100 meters as the small target, so I can finish my task easily. If I think about 800 meters at first, I will lose my motivation and give up quickly. Motivation is like the light in the dark, leading us to reach our destination. Find our aim and set up the small plans. We can make it anyway.

每个人都需要前进的动力，这样无论他们遇到什么样的困难，都可以看到希望，并坚持以达到目标。我为自己设立了小目标，这样就可以一步一步地取得进步。比如当我在操场上跑800米时，我会把每次的100米当做小目标，这样我就可以很轻易地完成我的任务。如果我一开始就想着800米，就会失去动力，迅速放弃。动力就像是黑暗中的光，引导着我们到达目的地。找到我们的目标和设立小的计划，就总能成功。

Now, our side of the car constant more up, the environment also increasingly worse!

That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do.

For example, we can go to school by bike or walk, it can exercise.

If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.

现在，我们身边的汽车不断的多了起来，环境也越来越糟糕!以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。
