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。

现在地球的环境越来越不好了，地球的身体到处是白色垃圾，再也看不见那湛蓝的天空，再也看不见茂盛的树林，再也看不见天边天际的大海 ……

现在的人类，为了方便省事，一律都用塑料用品。就拿塑料袋来说吧 ! 人们总把用好的塑料袋随手一扔，人在地上，风一吹，满天都是，若扔在菜地里，因为塑料袋是一种特别物质做成的，就算过上几百年，甚至几千年它也不会被土地吸收。有的工厂为了一点点排污费，把污水偷偷排放到附近的小溪，河流里。这导致河里的鱼死亡，浮上水面，发出阵阵恶臭，者不仅破坏了当地居民的生活，还破坏了生态环境，这些污水如果流进大海，后果真是不堪设想。

如果我们不行动起来，最终是自取灭亡的。我们不能为了自己的利益而破坏得球的生态，我们不能为了方便破坏地球的环境，现在地球的温度越来越高，已经发起了低烧，大部分的土地在沙漠化，大面积干旱，在北极坚持了 3000 多年的冰架最终还是熬不住热，塌了。再乱砍乱伐，太阳会射进大气层，到时候人类就会灭亡了。

我向全球人呼吁 : 我们只有一个地球!不要在破坏地球的生态环境了

The national level protection animal giant panda, have you ever seen giant pandas? Come and see! The following is a lovely giant panda, see how delicious it eats! The smile is so lovely.

Do you know how pandas digest bamboo? Researchers have found that the giant pandas digestive tract is short and simple, and there is no such thing as a long, plant-eating animal with a thin gut and a complex stomach or a developed cecum. In addition, the giant pandas genome sequences announced in 2009, after they found the giant panda to the lack of some help in the digestive tract herbivores digest cellulose and hemicellulose (they are the main components of the fibrous plant diet) enzymes. This is confusing for researchers, and how does the lack of these necessary conditions digest bamboo?

Researchers use of gene sequencing technology, analysis of more than 5000 ribosomal RNA sequences, eventually in the giant panda, found a variety of digestive tract bacteria and some microbes are very similar to grazing animals. These help animals digest cellulose in their bodies, and seven of them are unique to the pandas digestive tract. Bye bye!

shark-skin like swimsuit

A new high-performance swimsuit,developed by mimicking the skin of sharks,will be worn by top athletes in Athens from this week.

The revolutionary new fabric,developed by Speedo,is the result of four years of research and development that began with the study of shark skin at the Natural History Museum .

The new swimsuit,called Fastskin FSII,increases a swimmers speed by reducing passive drag through water by up to 4% more than the next best swimsuit.

Research into shark skin texture and movement through water was carried out under the guidance of Natural History Museum fish expert Ollie Crimmen.

Tiny teeth cover the surface of a sharks skin and the shape and positioning of these teeth vary across the body to manage the flow of water.

With these findings Speedo created a full bodyskin with different fabrics on different parts of the body and for the first time,male- and female-specific and stroke-specific swimsuits.

环保是我们这个时代充满争议的流行词，但同时是保护环境中极其重要的一点，我们如何做到环保，如何最环保，怎样才算环保呢，在以下内容中，我们将知道。

环保是指环境保护。环保是指人类为解决现实的或潜在问题，协调人类与环境的关系，保障经济社会的持续发展而采取的各种行动的总称。

现在，我们生活活中，最严重的环保问题就是土壤遭到破坏，气候变化和能源浪费。据参考消息报道，110个国家可耕地的肥沃程度在降低。在非洲，亚洲和拉丁美洲，由于森林植被的消失、耕地的过分开发和牧场的过度放牧，裸露的土地变得脆弱了。大地母亲已经变的面黄肌瘦，请好好保护我们的大地母亲!有专家预计，在不久的将来海平面将升高，很多岛屿都将会被淹没。

那我们该如何制止这一切的发生呢?其实，保护环境并没有想象中的那么难，只要我们从小事做起，就一定会让地球焕然一新的，比如：多使用环保袋，尽量避免用塑料袋;尽量坐公交车，尽可能的减少汽车排放的废气;平时多步行，骑自行车，锻炼身体又保护环境……除此之外，还有很多很多，只要我们从小事做起，积少成多，积沙成塔，就一定会让地球重还以前的面貌。

让我们为地球的将来而奋斗吧!

There are still many problems of environmental protection in recent years。 One of the most serious problems is the serious pollution of air， water and soil。 the polluted air does great harm to people’s health。 The polluted water causes diseases and death。 What is more， vegetation had been greatly reduced with the rapid growth of modern cities。

To protect the environment， governments of many countries have done a lot。 Legislative steps have been introduced to control air pollution， to protect the forest and sea resources and to stop any environmental pollution。 Therefore， governments are playing the most important role in the environmental protection today。

In my opinion， to protect environment， the government must take even more concrete measures。 First， it should let people fully realize the importance of environmental protection through education。 Second， much more efforts should be made to put the population planning policy into practice， because more people means more people means more pollution。 Finally， those who destroy the environment intentionally should be severely punished。 We should let them know that destroying environment means destroying mankind themselves。

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。

为了保护环境，各国政府做了超多的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。

我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当透过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自我。

当我读完《与环保同行之哭泣的海洋》这本书之后，使我深受启发。对海洋素不知道的我，通过阅读，我了解了许多关于海洋的知识。

2003年10月15日，北京时间9时，中国首次发射的载人飞船“神舟5号”冲破大气层，遨游太空才发现，地球并不是想象中，土黄色的星球，恰恰相反，地球的大部分都是蔚蓝色的海洋，说它是“地球”不如说它是“水球”更恰当些。

海洋中的鱼、虾、贝、蟹等许多海底生物都有着丰富的蛋白质，例如：从某些海葵中能提取出抗凝血剂，有一些海葵的提取物可治白血病，另外它还能治疗皮癣;河豚的卵巢、血液和肝脏有剧毒。从河豚身上提取河豚毒素，在医学上是一种良好的局部麻醉剂……在海洋中有许多珍宝，使人类的生活变得更充足，正因这样，那些贪婪的人就不惜一切代价来捕捉这些动物，使它们都频临灭绝。

我举个书中的例子：近海养殖业产生的残饵、残骸、养殖集体排泄物污染海水之后，而每只毛蚶一天过滤120升海水，当人类食用被细菌附着的海产品，在通过食物链进入人体，就会导致人群生病甚至死亡。1988年年初，上海爆发的轰动国内外的“甲肝事件”就是人们食用了病毒感染的毛蚶所致。

这件事让人们更重视对海洋的保护，同样也让我意识到我们因该号召每个人都要保护海洋，不要往海里扔垃圾让海洋恢复到原本生机勃勃的容貌。

Traditional Culture Wont Be Lost

It seems we are living in the conflict between modern and traditional cultures every day. Hearing the blaring of horns the moment you step out of your house, seeing the so called "pop" the moment you open your eyes, you cant help thinking, "Will the traditional culture be gradually lost?"

Many people believe so. They may put right in front of you all the evidences they can dig out. They may argue that people are rushing to restaurants instead of cooking at home, listening to pop music but not traditional, wearing in a way people couldnt imagine ten years ago. Modern people like the air of freedom, not to be restrained by traditions. They offer this long list, only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading

and will be lost at last.

Though we are now living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy are part of our daily life. Though this is a skeptical age, and our faith has weakened, our confidence in some aspects of the traditional culture should and would never be lost.

Wouldnt you agree that our traditional culture is always credited with modesty, politeness and respectfulness, which have always been treasured for more than five thousand years?Even in this modern world, people still admire those with good manners, those who are polite to others or respectful to old people.

Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?

So there may just be some changes in our lifestyle or our attitudes towards life, but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.

The traditional culture will never be lost, I believe.

[保护环境英语作文例句

Recently, our efforts to protect wild animals was questioned by the public,

because the news is keep reporting that more and more wild animals was killed by

human beings, especially the very precious one. Innocent animals was dead for

their meat, fur and tooth, it was just used to fill up human beings desire. In

my point of view, the wild animals were protected effectively still has a long

way to go.

Firstly, people should try harder to make a better place for animals. The

land where the wild animals live was deprived by human being. For hundreds

years, people cut the trees to make land for their living and farming, wild

animals homeland was took, they have no choice but run away. What is more,

human beings break the food link in nature; wild animals can not find enough

food to keep alive. There is no doubt that the destruction of nature has become

a big problem to kill wild animal, for instance, a polar bear was starved to

death because of the greenhouse effect, the ice was melt away, the seadog and

fish that polar bear like to eat are far away from them. For those reasons,

people should protect the environment first if they want to protect wild animals

effectively.

Second, no buying, no killing. Some rich people like to wear fur coat, they

treat it as a status symbol, especially for rich woman, they think animal fur is

beautiful and warm, they will never consider that the fur they wear for years is

the skin that animal wear for their whole life, and they knew how bloody when

people took the fur from animal but they choose to ignore it. If people do not

buy the fur and tooth, lots of wild animals will be survived.

In sum, wild animals are our friends, we should give back and protect their

homeland, and stop buying their body part, or our future generations will see

them in zoo and museum.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish into the sea.Its easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.

I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.

We must act now before it is too late!

With the development of economic,people now living a better life.But at the same time,many of the earths animals have already died out.

Nowdays,more and more animals lost their homes and they have no choice but to face the sorrow of missing relatives and friends.What makes it comes about?What makes their living condition even worse?The answer is human!Some people cut down plenty of trees to make fortunes,which damaged the forest and made the animals lost their home.And there are also some greedy people even hunt for animals to make money,which lead a terrible result--a number of animals are in danger.

Each anmimal especially wildlife is our friend,they play an important role in ecological balance.So,lets take action,planting trees,buliding birdhouses and so on to pretect our earth.

随着经济的发展,人们现在过着更好的生活。但与此同时,地球上的很多动物已经灭绝了。

现在,越来越多的动物失去了家园,他们别无选择,只能面对失踪亲友的悲痛。它是什么?是什么让他们的生活条件更糟糕吗?答案是人类!有些人砍伐大量的树木让财富,破坏了森林,使动物失去了他们的家园。甚至还有一些贪婪的人寻找动物赚钱,导致一个可怕的结果,许多动物都处于危险之中。

主义每个动物特别是野生动物是我们的朋友,他们在生态平衡发挥重要作用。让我们采取行动,种植树木,建筑物的鸟屋等等来保护我们的地球。
