中学生英语演讲稿保护大自然2篇 作文怎么写热门20篇

Water is the source of life, life, human health without water. Few people can not eat, but you cant days without water. And now, global 20 million people are in severe water shortages!!!!!!!!!! Water crisis, has to humans was a wake-up call!

Chinas water resocurces, but most of all, is the sea water of the sea is salty, is not directly drinkable, Plus most all freshwater distribution in cold north and south poles and permanent snow mountain, this place is freshwater resources. And uneven distribution, east of north, south west of less than, the local water.

When I was a child I want to tap water, water has been flowing nonstop not? Mom and dad always told me what was recently and drought.

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。

I am a student from Xinhua Middle School in Chongqing，China. Informed that

you have a vacancy for a student to serve as the spokesman for animals, I cannot

resist my inner excitement,hoping to seize the opportunity to do something for

animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I

go and whatever I do, I usually keep in mind that animals are angels from the

heaven, which bring us endless comfort and pleasure. I have been a panda lover

since my childhood. Panda is so lovely that brings fun to people and they are

regarded as the treasure of our country. Unfortunately，such a rare species is

now faced with the danger of being extinct。What I am eager to do is to raise

people’s awareness of animal protection and appeal to more people to care for

our earth companies.

It is my belief that all human beings can make a difference together. I

would appreciate it if my application could get your approval.

暑假期间，我会志愿者在兽医的，所以我看到很多狗。米妮是迄今为止最有趣的前瞻性的狗我见过。薄卷发几乎涵盖她的香肠状体。她偷听时眼睛总是似乎很吃惊。而她的尾巴看上去像老鼠的尾巴。

她被带到可以付诸入睡，因为她的主人不想让她再去看兽医。我想有一个甜美米妮的个性，虽然。 “任何人都不应该看她的容貌她，“我想。因此，兽医绝育她，给她必要的镜头。最后，我在当地报纸上刊登广告米妮：“有趣的前瞻性的狗，品行端正，需要温暖的家庭。“

当一个年轻的男人叫，我警告他，米妮是陌生的。手机上的男孩告诉我，他的祖父的十六岁的狗刚刚去世。他们希望米妮不管。我给了一个很好的浴缸和米妮拍过了什么是她蓬乱的头发了。然后我们等待他们的到来。

最后，老车开了许多在兽医的前面。两个孩子跑到了门口。他们夺到他们的武器米妮冲她出去他们的祖父，谁是在车里等着。我急忙在他们身后看到他的反应，美妮。

车内，祖父怀抱米妮抱在怀里，抚摸她柔软的头发。她舔他的脸。她拉塔尔摇摇周围如此之快，它看起来像它可能飞了她的身体。这是在第一次舔的爱。

“她太棒了！“老人感叹道。

我很庆幸找到了好米妮家，她当之无愧。

那是当我看到祖父的眼睛是一个乳白色的颜色- 他是个盲人。

During the summer vacation, I would volunteer in the veterinarian, so I saw a lot of dogs. Minnie is so far the most interesting looking dog Ive ever seen. Thin curly hair almost covers her sausage. Her eyes always seem to be surprised when she eavesdropp. And her tail looked like a rats tail.

She was taken to sleep, because her master did not want her to go to the vet again. Id like to have a sweet Minnie personality, though. "No one should see her," I thought. So the vet sterilize her and give her the necessary lens. Finally, I advertised in the local newspaper Minnie: "an interesting looking dog, a good character, and a warm family. "

When a young man called, I warned him that Minnie was unfamiliar. The boy on the phone told me that his grandfathers sixteen year old dog had just died. They want Minnie to do whatever it is. I gave a nice bathtub and Minnie what was her dishevelled hair. And then we waited for them to come.

At last, the old car was in front of the veterinarian. The two children ran to the door. They took their weapon, Minnie, and rushed her out to their grandfather, who was waiting in the car. I hurried behind them to see his reaction, minnie.

In the car, grandfather held Minnie in her arms and stroked her soft hair. She licked his face. She rocking around so fast that it looks like it might fly her body. This is the first lick of love.

"Shes great! "The old man sighed.

I was glad to find a good Minnie family, and she deserved it.

It was when I saw that my grandfathers eyes were a milky white color - he was a blind man.

In recent years, I find it easier to our resources dried up. All of these, because we have recently a lot of collection resources, leading to our mothers are dwindling.

What is the mother of all resources less and less? Is, of course, we humans excessive spoiling dont cherish, would cause such a serious result. Our earth forest area has reached 600 million hectares, the figure is due to our human previously has important sense to protect the environment, know that if you dont have a good environment, we wont be able to breathe to the light wind gently brushed the grass surface sweet taste. And now? Us that the earths forest area is still not arrived 6 hectares, this kind of situation, it is because we humans cut down trees and destroying forest without restraint, make almost fell by 1% in each of the forest area in the world, now our protection in the nature of the important consciousness is more and more shallow, dont take care of the objects around, as the forest is less, the first bite of the air we breathe is less and less fresh...

Is not destruction of forest resources, and our mineral resources. It is limited, now our production technology constantly improve, the accelerating speed and shortage of some minerals occurred, even dried up. Until then, we will always stay in the desolate landscape.

In the face of these, can see there are so many resources in we lost too much! We rely on resources too much! All around us, little drops of the resources are in decline, if lost it all, we will how to live! So, let us sincerely treat our mother earth, try to cherish, to cherish. If only use a small plastic bag, it should not be too!

Let us act, to defend the earth!

近几年来，我发现我们的资源越来越容易枯竭了。这些，都是因为我们最近大量的采集资源，才导致我们的母亲日渐枯竭。

是什么让我们这位母亲的资源越来越少了呢?当然是我们人类过度的糟蹋不珍惜，才会造成这样严重的结果的。我们的地球森林面积曾经达到了6亿公顷，这笔惊人的数字是由于我们人类以前有着保护环境的重要意识，深知如果没有了良好的环境，我们也就无法呼吸到微风轻拂过草面的甜美味道。而现在呢?我们地球的森林面积还不到了6公顷，这种状况，就是因为我们人类不加节制地砍伐树木和毁林开荒而造成的，使世界上的森林面积几乎每年减少了1%，现在我们的保护在自然的重要意识越来越浅，不爱护身边的一草一木，由于森林逐渐变少，我们呼吸的第一口空气也就越来越不清新……

还不止森林资源被破坏，还有我们的矿产资源。它是有限的，现在我们的开采技术不断提高，速度不断加快，使某些矿种发生短缺，甚至面临枯竭。到那时，我们将永远呆在荒凉的大地上。

面对这些，可以看出来我们失去的资源真是太多太多了!我们的依赖的资源也太多了!在我们身边，点点滴滴的资源都在减少，如果失去了这一切，我们将如何生活!所以，让我们真心地善待我们的地球母亲，努力去珍惜，去爱惜。哪怕只是多用一个小小的塑料袋，这也是不应该的!

让我们行动起来，保卫地球吧!

Nature, the environment which human beings live by, is magnificent and unique. There si only one earth with super living conditions in the universe. We should have cherished nature and preserved it. Conversely, however, we have been continually spoiling it, even to a shocking degree. Now lets see what we have dong.

Thousands of trees have been cut down per year, which has caused soil erosion. Hundreds of thousands of tons of CFCS have been left in the higher sky in the last decade which has led to the ozone layer leak above the South Pole that covers an area of that of the United States. Million tons of fuel containing nitrogen and sulphur have been consumed per year, which has eventually resulted in acid rain throughout the world.

Similarly, ecology has been affected as well. And considerable number of species have been extinct as the years go by many creatures which were common in the past are becoming less and less, even rare. The Tibet antelope, for instance, is a good example. Since the antelopes of Tibet have a part of fur on their body which can be made into a precious cape, driven by some lawless dealers many villagers killed antelopes excessively and shocking for the large suns of fortune. Because of this, the number of the antelopes of Tibet has sharply fallen from over one million to less than one hundred thousand. And whats more, the number has now decreased by 20 thousand per year. Qing Zang Platean, which was their homeland, is their tombs now.

This is how nature has suffered what we have done to it. However, nature and suffer any more. She lost her temper and could no longer possibly put up with humans. She gave humans harsh punishment, which she thought they deserved. The acid rain has caused the less of more than 100 billion dollars throughout the world per year. And because of desertification , soil is becoming more and more barren. The soil of many planes is now until for growing plants. The air is less fresh, and a lot of people even get many stranger diseases. Those are all the punishment of nature to humans pollution. On the other hand, human being suffer a lot as well.

So it leads to a serious of questions--

Why cant we live harmoniously with nature?

Why cant we set a balance between human and nature?

Why cant we pay more attention to nature and try to reserve it?

Therefore, before we take immediate measures to do something, we should be aware of the fact that "Conquering the nature" will never be our goal, instead, we should take the nature as our intimate friend. Preserving nature is not only preserving our home, but the civilization of human community as well.

自然,人类生活的环境,是宏伟的和独特的。si只有一个地球和宇宙中超级生活条件。我们应该珍惜自然,保护它。相反,然而,我们一直在不断地破坏它,甚至令人震惊的程度。现在让我们看看我们有盾。

每年成千上万的树木被砍伐,造成了水土流失。成千上万吨的氯氟烃已经在更高的天空在过去十年里导致南极上方的臭氧层漏洞,美国的占地面积。几百万吨含氮和硫的燃料消耗,这最终导致全世界酸雨。

同样,生态也受到影响。和相当数量的物种已经灭绝,随着年龄的增加许多生物这在过去是很常见的正变得越来越少,甚至罕见。例如,西藏羚羊就是一个很好的例子。自西藏的羚羊有毛皮在他们身体的一部分,可以做成一个珍贵的披肩,由一些不法经销商许多村民杀羚羊过度和令人震惊的大太阳的财富。正因为如此,西藏的羚羊的数量已经从一百万降至不到十万。,更重要的是,现在每年减少了2万。清代藏高地,这是他们的家园,现在他们的坟墓。

这就是大自然遭受了我们所做的。然而,自然和痛苦。她失去了她的脾气,不再能忍受人类。她给了人类严厉的惩罚,她认为他们应得的。酸雨造成的少每年全世界超过1000亿美元。正因为沙漠化,土壤变得越来越贫瘠。现在许多飞机的土壤,直到种植植物。空气不新鲜,很多人甚至许多陌生的疾病。这些都是自然对人类的惩罚污染。另一方面,人类遭受了很多。

所以它会导致一个严重的问题—

为什么我们不能与自然和谐生活吗?

为什么我们不能建立人与自然之间的平衡?

为什么我们不能更加关注自然和试图储备吗?

因此,我们立即采取措施做某事之前,我们应该意识到这样的事实:“征服自然”永远是我们的目标,相反,我们应该以自然为我们亲密的朋友。保护自然不仅是保护我们的家园,但人类社会的文明。

Chinahas a very long and brilliant history, whose people are so friendly and hospitable. But I am wondering why some people pay such little attention to the environment and nature. In many places of the countryside, rivers have become stinking sewers and brooks have disappeared. Heaps of garbage obstructs the scarce flow of dirty water. The grounds are littered with plastic bottles and bags. People are cutting down trees even though it is illegal. In some towns, rubbish is hidden behind walls. Garbage cans are often of little use, making cleaners must rush all day long and also by night to clean the rubbish.

中国有着悠久辉煌的历史，人民十分友善好客。但是我很好奇为什么有些人对自然和环境那么不在乎。在乡下的很多地方，河流已经变成臭哄哄的下水道，小溪也消失了。成堆的垃圾阻碍了污水难得的流动，地面上到处是丢弃的塑料瓶和塑料袋。尽管乱砍滥伐是违法的人们还是砍倒树木。在一些乡镇，垃圾就隐藏在墙后面。垃圾箱基本上没起到作用，使得清洁工人必须整天日日夜夜来回清理垃圾。

This lack of consideration for nature in general is extremely detrimental to children’s education, toChina’s image, to public health, to tourism and to the future.Chinais the common treasure of all Chinese, and we should live up to be a member of this big family, a descendant of 5000-year-plus ancient civilized country. I think the environment must absolutely be strictly protected by all means. This protection should go at the same pace as the marvelous development of the nation.

这种缺乏考虑大自然的行为一般都会对孩子的教育，对中国的形象，对公众的健康，对游客以及对未来很不利。中国是所有中国人共有的宝贵财富，我们必须成为这个大家庭中合格的一员，成为5000年古老文明的国家的子孙。我认为必须想方设法严格的保护环境，这种保护应该与国家的快速发展的步伐相一致。

In this respect,Germanyis a rare model and leaves me a very deep impression. After you have an exciting tour around in this country for a week or so, it is unnecessary for you to polish your leather shoes. Personally, first of all, the strong awareness of people’s environmental protection; then, the advanced technology applied in the field of preserving the nature; We can learn form others in building China into one of the most environmentally friendly places in the world.

在这一方面德国是少有的模范，给我留下了深刻的印象。当你环游这个国家大约一周之后，你没有必要去擦你的皮鞋。在我看来，首先是因为那里的人们保护环境的意识非常强;其次，在保护大自然这一领域应用的技术十分先进。我们可以向别人学习，把中国建设成世界上最环保最友好的国家。

金山银山，不如绿水青山。我镇开展“爱护环境，美化家园”为主题的环境卫生整洁行动以来，镇村环境卫生面貌持续改善，群众卫生意识明显提升，创造干净、整洁、舒适、优美的镇域环境，既是全镇人民的强烈愿望，更是全面推进我镇城乡一体化中心镇建设的现实要求。为此，我们向全镇人民倡议：

一、养成良好的卫生习惯。请您自觉打扫门前屋后卫生，确保门前屋后干净整洁，无裸露白色垃圾，无污水;公路两旁不堆放放柴草物料，做到不乱倒垃圾，不要将垃圾倒入河道、沟渠、水塘;请不要将禽畜粪便直接排入水域，人人自觉养成讲卫生、爱整洁的习惯。

二、落实垃圾分类减量“五字方针”。卖—卖掉废纸、塑料、玻璃瓶和金属等可回收的废品。埋—建筑垃圾、卫生间废纸、纸巾、碎玻璃片、煤灰等难以回收的废弃物进行填埋处理。烧—烧掉废弃衣服、书包、枯枝败叶等可燃废物。沤—将剩菜剩饭、骨头、动物内脏、菜根菜叶、果皮等食品类废物，经生物技术就地处理堆肥。收—废电池、废水银温度计、农药瓶(袋)等有毒有害物质需要特殊安全处理的废品由废品回收站统一回收。

保护大自然是人们应该做的事。

一天放学，我透过窗子看到有人在砍树、污染空气……破坏大自然。我连忙跑过去大声喊道：“你们不能这样做，要爱护大自然，让城市更美好！”刚说完，他们立刻放下手中的物品，还对我说：“让我们一起帮小树除草、施肥，等它们长成一棵枝繁叶茂的参天大树吧！”“好啊，好啊。”我说。我拿出工具，把我需要做的事给做完了……

那天晚上，我和爸爸做出一张表，上面写着几行字：从今天开始，我宣布你们不准做任何对大自然有破坏的事，要保护大自然。如果再破坏，就罚种棵树。人们收到这份小报，再也没有破坏过，每天都有清新的空气在我的鼻子下飘过，真是太美了！

保护大自然是很重要的事，如果人人都保护，才能将世界打造得更美好。

The beauty of nature is like a magician. To daub on light green, spring to summer with a dark green, and, with dazzling aureate autumn to winter again put on a white coat; Ding-dong of the spring water gently singing tune, spectacular sea in rhythm, those little the singer with the wind also show up their indirect voice; Beautiful picture of nature is the blue sky white clouds, green hills and water, flowers, quiet mountains...

What a sight!

However, such a view, so beautiful, because human desire is dont have much, everywhere is named "tall buildings" tree; Flow of the river is called "car" of water droplets; Beautiful mountain "has been renamed as" factory "; Beautiful blue sky white clouds seemed to fit the nobility, clothed in black.

Oh my god ~! The beauty of the earths natural villages? Where is she? Oh, she is still there, just for old face... These, is she the children are making! The human and the nature cant coexist? As long as we are taking the path of sustainable development, mother nature will not be ill-treated in human ~! But now? Human unchecked, makes the natural mother scarred, also sped up the earths resources to reduce...

Stupid human ah, you really are in knowingly ah ~! Preached that environmental protection, and increase the demand, this is the face of love your mother? Action! Action! With the practical action to implement environmental protection, for future generations point f!!!!!

美丽的大自然好似一个魔术师。给春涂抹上淡淡的翠绿，赠予夏一抹深绿，又为秋染上耀眼的金色，再给冬披上一件白色的大衣;叮咚的泉水唱着轻柔的调子，波澜壮阔的大海则打着节拍，那些小小的歌唱家们伴着清风也展示起了自己婉转的歌喉;大自然中美丽的图画则是那些个蓝天白云，青山绿水，鸟语花香，幽静山林……

多美好的景象啊!

可是，这样的景色，这样的美好，因为人类的欲望已经所剩不多，到处可见的是名叫“高楼大厦”的树;流动着的河是名叫“汽车”的水滴组成的;美丽的山已经易名为“工厂”;美丽的蓝天白云似乎也装起了高贵，披上了黑色的纱衣。

天啊~!那个美丽的地球自然村呢?她到哪里去了?哦，原来她还在，只不过是换成了苍老的容颜……这些，正是她那些儿女们所一手造成的~!人与自然难道就不能和平共处吗?只要我们走可持续发展道路，自然母亲是不会亏待人类的~!可是现在呢?人类无节制的索取，使得自然母亲伤痕累累，也加快了地球资源的减少……

愚蠢的人类啊，你们真的是在明知故犯啊~!一边口口声声的说环保，一边又加大索取，这就是你们爱母亲的表现吗?行动!行动!用实际行动来实行环保，为子孙后代积点福吧!!

今天，天气晴朗，阳光明睸，我和妈妈来到马峦山郊野公园。我们一边上山一边欣赏路边的美景。看，那小溪里的水多么清澈，像玻璃一样透明；那飞溅的瀑布多么壮观，真像从山上垂下来的一块白布。听，鸟儿在树林里叽叽喳喳地唱歌，多么的快乐！

我们登上山顶，继续向大梅沙进发。在路上我看见许多别墅，这些房子虽然很漂亮，但是我并不喜欢，因为它们的建造不知道砍伐了多少树木。

终于，我们走到了大梅沙海滨公园，在栈道上看一望无际的大海，走近可以看见一条条小鱼畅游在蔚蓝的大海中，大海真美啊！看得我都不舍得离开。

但是我总担心有一天鸟儿不再欢乐地歌唱，鱼儿不再欢快地畅游。因为我们正在日益破坏着它们的生存环境，工厂排放出来的污水污染了一片片海洋，过度砍伐树林逼着可爱的鸟儿离开它们的家园。每次想到这些场景都为小动物们感到担忧，我决定长大后要做一个自然保护主义者，向大家提倡是爱护环境，保护大自然。

让我们一起喊出我们的口号：保护自然，从我做起！

As it’s known to all, China is popular for its emperor of bicycles. This is because our country is still a developing country and few people can afford private cars. The demand for a means of transport is met by making millions of bicycles available.

Riding a bicycle has a lot of advantages over driving a car. First, it is a physical exercise to ride a bicycle. In contrast, sitting in the car, one tends to gain weight. Besides, it is much more economical to ride a bike than drive a car. On the one hand, the only fee a bike-rider has to pay is the annual tax. However, the annual fees for a car are costly. On the other hand, a bike neednt be equipped with a parking lot, but a car must. Most important of all, it is beneficial to the environment to ride a bicycle because the bike doesnt consume petrol; it is a pollution-free transport. In contrast, the exhaust released by the car is harmful to the environment.

Since China is a developing country with a large population, bicycles will still be the most popular means of transport in China for quite a long time. Most people will still ride bicycles to go to work or to school. The emperor country of bicycles will remain for at least dozens of years.

I am a student from Xinhua High School in Chongqing，China。 Informed that you have a vacancy for a student to serve as the spokesman for animals， I cannot resist my inner excitement，hoping to seize the opportunity to do something for animals 。

In my mind，nothing can delight me so much as caring for animals。 Wherever I go and whatever I do， I usually keep in mind that animals are angels from the heaven， which bring us endless comfort and pleasure。 I have been a panda lover since my childhood。 Panda is so lovely that brings fun to people and they are regarded as the treasure of our country。 Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies。

Although people are now said to protect animals, but there are a lot of people wrong-headed, continue to hunt animals, cause many animals to the road to extinction. Humans and animals to see, sold at the same time, made from animal skins coat... But these people ever think, if you are an animal, are hunted by humans, what would you think? Some people say: "Im not a animal." But now hunted animals, animals would like to have? No, never. Although some people know how to care for the animals, but they will only pretending to go to the education of others, and themselves but also damage the environment, killing animals, so enthusiastic tasting animal meat is delicious. Take the puppy around us, for instance, although not a national secondary other rare animals, but also our good partners, whether master how to use it, it still is very dedicated, but humans find dog meat is delicious, began to kill the dog.

Now, some animals have almost extinct, take the crocodile, for instance, although it is very fierce, but humans are more fierce. And in the eyes of human beings, crocodile skin can be made into the luggage, handbags, wallets, shoes and other goods. Because of some organs from animals has the prominent economic value, thus become a subject of human plunder use, become the main factor of extinct animals. So the crocodile, has now become almost extinct animals.

Animal friends, a lot of destruction of human will have serious adverse consequences, ecological environment caused by serious imbalance, so that the human living environment is destroyed. Eliminate animal, is to eliminate human oneself, if one day the animals in the world are gone, that human can survive? To protect animals, cherish this nature of every creature! Let us start from now, to protect animals, make the world a better place!

虽然人们现在都说要保护动物，但是还有很多人执迷不悟，继续猎杀动物，导致许多动物都走向了灭绝的道路。同时人类还拿动物来观赏、卖钱，用兽皮做大衣……但这些人有没有想过，如果你是一只动物，却遭到了人类的猎杀，你会怎么想?有些人说：“我又不是动物。”但是现在人类大量捕杀动物，动物会愿意吗?不，永远不会。有些人虽然知道怎样去爱护动物，可是他们只会假惺惺地去教育别人，而自己却照样破坏环境，猎杀动物，照样兴致勃勃的品尝动物鲜美的肉。就拿我们身边的小狗来说吧，虽然不是国家一二级别的珍贵动物，但也是我们身边的好伙伴，不管主人怎么使唤它，它仍然很兢兢业业，可是人类发现狗肉鲜美，就开始捕杀小狗。

现在，有些动物已经快要灭绝了，就拿鳄鱼来说吧，它虽然很凶猛，但人类更凶猛。而在人类的眼中，鳄鱼皮可以制成行李箱，手提包，钱包，鞋等物品。就是因为有些动物身上的器官具有突出的经济价值，由此成为被人类掠夺利用的对象，成为动物灭绝的主要因素。所以鳄鱼，现在已经成为快要灭绝的动物了。

朋友们，动物的大量毁灭对人类将产生严重的不良后果，造成生态环境严重不平衡，从而使人类的生存环境遭到破坏。消灭动物，就是在消灭人类自己，如果有一天世界上的动物全都消失了，那人类还能生存吗?要保护动物，珍惜这自然界里的每一个生灵吧!让我们从现在做起，保护动物，使世界变得更加美好吧!

Remember last years summer vacation, my father and I went for a walk EHu edge, a way, Im kind of shouted thirsty, so my father on the side of the road store bought me a Popsicle. I ate and go, soon finished eating, carelessly threw the ice sticks into EHu. Dad saw, reminded me immediately; "Coco, cant litter oh! If everyone like you to throw garbage in the lake, the beautiful EHu lake becomes waste." Im ashamed of say: "know, next time I must not litter." Dad smiled and stroked my head and said: "the earth is our home, we should protect it, cherish it, let the sky bluer, the water cleaner, the grass is greener." I naughty to say: "oh, that is, everybody has said, the city is my home, clean environment depends on everybody. I understand." From then on, I no longer throw garbage.

I want to take care of the environment is closely related to everyone, so lets start from everyone!

今天，我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假，我和爸爸一起去鹅湖边散步，走了一段路，我就一个劲的喊口渴，于是，爸爸就在路边的小店给我买了根冰棍。我边吃边走，一会儿就吃完了，随手把冰棍棒往鹅湖里一扔。爸爸看见了，马上提醒我说;“可可，不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾，这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说：“知道了，我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说：“地球也是我们的家，我们应该保护它，爱护它，让天更蓝，水更清，草更绿。”我调皮的说：“噢，那就是大家一直说的，城市是我家，环境清洁靠大家。我明白了。”让从那以后，我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关，所以要从每个人做起!

In China, we can see white trash, common throw the waste battery status, protect the environment, 500 - word composition. Well look at Japan, Japans battery and white trash are through strict processing, no breach of the garbage disposal in China. I once read an article, the article mentioned in humans to Mars, lets not say whether there are suitable for human survival on Marss atmosphere, can the living. Now we have already seen, the earth has been destroyed by us so, we not only not repent, dont have to destroy another planet?

If stubbornly wait until the whole universe are we break up, we dont know to repentance? To see our mother river - the Yellow River! It used to be so spectacular, so great, is our Chinese peoples pride, between the two generations, however, you see, now whats the mother river? And a mighty momentum before? Later we if asked about Yellow River between the two generations, we how to answer, again to see the big forest into a desert, all desire become the real "Yellow River", we must continue to damage the earth? We hate Japanese dont like Japan, but please put down hatred of learning how to learn Japanese environmental protection?

Japan is the largest country in the amount of wood, but never cut down their own trees, are imported timber in foreign countries, Japan is the largest country in the world forest area accounted for the proportion. There will be a high pollution projects on foreign production. Read this, Im afraid you will scold the Japanese are trying, but its not just proves that Japan is one of the most importance to the state environmental protection?

Protect the environment, starts from me!!!!!! How many times we shout the slogan, but we have to implement? The slogan was initially we shout out, but we never have the real action, and this slogan as a basic national policy by Japan, the implementation of the little hole. This not only make the Japanese environment better, or Japan become the least amount of pollution in the air.

So Japan seems really shameless, despicable! But this is our most the place. Take a look at our central news, headlines which which where leadership is always a meeting, what was said at the meeting, but that many are just fallen on deaf ears, which can truly implement good, is all lip service, had forgot. But foreign headlines always where where what happened, for help, for the common people for the real benefits. This is the difference between China and Japan. We sell wood at a low price to foreign countries every year, and then to spend hundreds of thousands of millions of the soil and water conservation management. This is the difference between China and Japan. The frequency of the Yellow River burst its Banks over the years more and more frequent, we do not pay attention to the Yellow River is not protected and the consequences of planted?

I say this is not I...... today, I really love our country. Really hope our country can better. I described above is the living example, we see is true, to everyone. Over the years we in the development of science and technology has obtained the very good fruit, but we on environmental protection and began at least fifty years of distance in the world, do we still shouldnt have a good look at what? I said these are want you to look at our countrys environmental protection problems, lets put the protection of the environment, starts from me "to carry out the point, make our country more beautiful, more beautiful.

I am a middle school student, not how good literary grace, not how beautiful words, it can write this. But I really hope our country better, become the pride of our all Chinese people!!!!!!

It is very urgent to protect the environment,! Lets action, and work together for the motherland tomorrow.

在中国，我们可以普遍的看到白色垃圾满天飞，废电池乱扔的状况，保护环境作文500字。我们再看看日本，日本的电池和白色垃圾都是经过严密处理的，完全没有上述中国垃圾处理上的疏漏。我曾经看过一篇文章，文章中提到人类移居火星的事，咱们先不说火星上是否有适合人类生存的大气，能不能活人。现在我们已经看到了，地球已经被我们破坏成这样了，我们不仅不悔改，难道还要再破坏另一个星球吗?

是不是硬要等到整个宇宙都被我们破坏完了，我们才知道悔改?再看看我们的母亲河——黄河!它曾经是那么壮观，那么伟大，是我们炎黄祖孙的骄傲，可是，你们看看，现在的母亲河是什么样子?还有以前磅礴的气势吗?以后我们的祖孙如果问起黄河，我们又该如何作答，眼看着大片的森林变成荒漠，条条清流变成真正的“黄河”，我们还要将地球继续破坏下去吗?我们恨日本不喜欢日本，但是请先将仇恨放下学习学习日本的环境保护好么?

日本是用木材量最大的国家，但是却从不砍伐自己国家的树木，都是进口的国外的木材，日本是全世界森林面积占国土比例最大的国家。将有高污染的工程全放到国外生产。读到这里，恐怕大家免不了要骂日本人心机重，但是这不正好证明了日本是最重视国家环境保护的吗?

保护环境，从我做起!!!这句口号我们喊了多少遍了，可是我们有落实过吗?这个口号最初还是我们喊出来的，但是我们从来都没有真正的行动起来，这个口号被日本当做了基本国策，落实的没有一点漏洞。这不仅使日本的环境变好起来了，还是日本成为了大气污染最少的国家。

这么看来日本好似真的很无耻，卑鄙!但是这却是我们最该学的地方。看看我们中央新闻，头版头条总是哪个哪个领导在哪开会，会上说了些什么，但是那很多都只是耳旁风，有哪个能正真落实好的，全都是嘴上说说，过了就忘了。但是外国头版头条总是哪里哪里发生了什么，都是求帮助的，真正为老百姓谋的了福利 。这就是中日之间的差别。每年我们将木材低价卖给外国，然后又要花几十万几百万把水土治理好。这就是中日的差别。这些年来黄河决堤的频率越来越频繁，这不都是我们不注意黄河保护而种下的恶果吗?

我今天说这些并不是我崇洋媚外，我真的很爱我们的国家。真的希望我们的国家能越变越好。我上面描述的都是我们看到的鲜活的例子，都是真正的，大家有目共睹的。这些年来我们在科技发展上取得了很不错的硕果，但是在环境保护上我们却与世界上拉开了至少五十年的距离，难道我们还不该好好反思一下吗?我说这些是想让大家注视一下我们国家的环境保护问题，让我们把“环境保护，从我做起”落实到点上，让我们的国家变得更美，更漂亮。

我是个中学生，没有多么好的文采，没有多么华丽的词语，这能写到这了。但是我真的希望我们的国家变得更好，成为我们所有中国人的骄傲!!!

保护环境，刻不容缓!让我们行动起来，为了祖国的明天而一起努力。

Grilled chicken. The roast duck. All kinds of meat, already is normal on table a "routine". Television also reported many save a national protected animal, encourages people from all over the world to protect animals. But, why do some people will do whatever it takes to save animals, and some will be on the table for people to enjoy? Not advocate protect animals?

The answer is very simple, because people at all costs to save animals is called "the state-level protection", and was called "poultry" on the table. Why is that? They are also lively individual life; There are also mom and dad love; a lovely kid The same is collectively known as animals. However, why? To protect rare animals, but more to eat. Side in the title of "animal protection", there are big mouth to bite a serve fish or fowl. Why the national birth will be protected, live more comfortable than some vulnerable groups, and poultry was born is raised, waiting for them is cruel, and then made into a variety of delicious, is on the table, is to eat their meat.

Isnt their life life? Why do this to them? If one day, in our own to be they kill, and then made into a variety of delicious, for them to enjoy, our own feelings of what?

Although I was not a great writer, cannot use a beautiful sentence touched your heart, but I want to say only one forever, also is the life should be respected, we have no right to decide the life and death of others, feeding them, at best, is the behaviour of a love.

Their life is life, watching, please protect your side weak life, thank you!

烤鸡;烤鸭;各种各样的野味，早就是餐桌上见怪不怪的一道“家常便饭”了。电视上也报道过不少拯救国家级保护动物的节目，提倡世界各地的人们要保护动物。可是，为什么有的动物人们会不惜一切代价去挽救，而一些就要被摆在餐桌上供人们享用呢?不是提倡保护动物吗?

答案很简单，因为人们不惜一切代价拯救的动物叫“国家级保护”，而被摆在餐桌上的叫“家禽”。为什么?它们同样是活泼可爱的生命个体;同样是有爸爸妈妈疼爱的乖小孩;同样是被人们统称为动物。可是为什么?稀少的动物要保护，而多的却要吃掉。这边打着“保护动物”的头衔，那边却大口大口地咬着鸡鸭鱼肉。为什么那些国家级一出生就要被保护起来，过着比某些弱势群体还要舒服，而家禽一出生就是养大，等待它们的就是残忍的虐杀，然后做成各式各样的美味，被摆在餐桌上，就是为了吃它们的肉。

难道它们的生命不是生命吗?为什么要这样对待它们呢?如果有一天，换我们自己要被它们杀掉，然后做成各式各样的美味，供它们享用，我们自己的感受会是怎样的呢?

虽然我不是什么大作家，不能用很美的句子打动你们的心，但我想说的永远只有一个：同样是生命就应该受到尊重，我们没有权利决定别人的生死，饲养它们，充其量就是一个爱心的行为举动。

它们的生命也是生命，看完，请您保护您身边弱小的生命，谢谢!

People plant a great number of young trees in the mountains.When the trees grow big and tall enough,they are cut down by workers and carried out of the mountains to the paper mill where fine paper is made from wood.Then it is taken to every corner of the country and used for different purposes.Some people use paper to copy writing,others use it to write something such as letters,reports and articles.When paper turns out to be of no use,the waste paper is collected and retreated in the recycling factory before being put into use again.

前几天看了“十万个为什么”书中提到“大自然是万物的朋友”我觉得这句话非常有道理，因为我们常常运用到大自然，大自然也不会像人一样小气，它们总是非常大方的让大家利用，让我们的世界变得很方便，也不需要再烦恼生活的问题了。

科学家因为找到更多资源，而人类们开始利用这些资源，最后，这些资源也对人类有很大的帮助。可是，人们以为这些资源会一而再，再而三的增加，永远不会减少，所以也就不懂得珍惜了，甚至还污染了这些珍贵的自然资源，也让那些可贵的资源不断的减少。

很久以后，大家才发现地球生气了资源快速减少中，可是也已经来不及了。天气变化多端，有时还会有狂风、骤雨、大旱…等天然灾难似乎已成生活常态，人们 也因此而死亡。看到这种情形，人们后悔莫及，也才警觉到要修复被破坏的地球，并且不再浪费来自大地的能源，除此之外，更要懂得节约使用大自然的资源呢！

还好，现在人类已渐渐地找回以前那种节约能源的心，表示我们还有机会和大自然作朋友，不然世界将走到无可救药的地步，最后还会引来死亡的危机。希望大家以 后都不要再随意浪费资源，更要小心地使用，好好的爱护它。将节能减碳爱地球变成一种生活习惯，再次和大自然做朋友。

国庆节演讲稿 中文

朋友，如果我问你什么是最高兴的事，也许你回答出各种各样的答案，但是，你无论如何也不会想到我们一位战士的回答，他说是“见到人”，见到人是最高兴的事。是啊，也许你会觉得诧异，但这却是酒泉卫星发射中心专用铁路巡线员的真实写照。这是今年春节我在军报上看到的一篇感人的--不!应该说是震撼心灵的报道。

自从我国在巴丹吉林沙漠深处建起酒泉卫星发射中心，就有了一条横穿戈壁、直达发射场的300公里的专用铁路。它是现在全国惟一一条由军队管理的铁路。路边上，孤零零有几座被称为“点号”的小屋，“点号”四周，沙海无边，荒凉得象月球，只有几丛骆驼刺在寒风中颤抖。“点号”里，就蹲着三两个长年巡线护路的兵。他们每天与外界交往的时间是一分钟。因为每天有趟军用列车路过这里，扔下点邮件和给养，停留一分钟。这就是他们见到人的惟一时刻。日复一日、年复一年的寂寞，这一分钟也就成了他们久久盼望的、也是他们最最高兴的时刻。

今年大年初一，一位记者到被称为“180”的小点号采访，那里住着小赵和小张两个士兵。小赵是一位来自江苏的已有3年兵龄的老兵，他说，他每天要去巡线一趟，每趟来回走20公里，当兵三年，相当于步行回老家一趟。新兵小张是四川中江黄继光家乡的人，他到点号的第二次巡线就遇上被称作“黑风”的沙暴，天地间黑压压一片，沙石劈头盖脸往身上砸，他说他抱紧铁轨整整一小时不敢动弹，差点没被埋在沙包里。说话间，小赵的姐姐从老家打来了电话，姐姐问：“你那里过年热闹吗?”小赵说：“热闹得很，有3个人呢，还有一条大黄狗”。“你那里冷吗?”，“不冷，暖和得很，才零下20度”。“你都3年没有回家了，爸妈以为你今年能回来过年，特意杀了猪，还几次到路口去守公交车。”这时，小赵的喉头滚了好几下，愣了半天，终于没能“幽默”出来。当记者告辞时，他俩紧紧地握住记者的手，久久不想松开，眼睛里突然溢出泪光，那眼神似乎在不加掩饰的恳求着：再留一会儿吧，哪怕是一分钟!

啊，一分钟，多么令人心颤的一分钟!看到这儿，我的心被震撼了，泪水也止不住掉了下来。我想，别说他们在那里要为我国在世界高技术领域占有一席之地，为实现中华民族千百年来的“飞天”梦想而拼搏，就是呆在那儿，也是奉献。 是的，作为军人，我知道，在雪山，在海岛，在荒原，在戈壁，有无数与小赵小张一样的士兵，为了祖国的强盛和人民的安宁，在默默忍受着艰辛与寂寞。作为军人，我更懂得，是军人这特殊的职业赋予了军人特殊的使命，特殊的使命赋予了军人特殊的追求。军人，也许就意味着奉献与牺牲。 难道不是吗?翻开中国革命的历史画卷，不难发现，其中最引人注目的便是那些为了祖国和人民的利益而驰骋疆场、马革裹尸的军人。从万里长征、八年抗战、南征北战到自卫还击、抗震救灾、抗洪抢险，多少年来，这支人民的军队，在党的绝对领导之下，经受着无数次血与火的洗礼，一次又一次向党和人民交出合格的答卷!就说那300公里航天大动脉，当年修建时就有120名忠骨埋在了沙丘。

小时候，我曾羡慕穿身军装，现在我终于实现了这个梦想，如今，我又跨进全军的高等学府――国防科技大学的校门。在这里，我又读到许许多多的银河人，他们将银河精神在新时代高高奏响，为响应江总书记“科技强军”的号召，在夜以继日的、默默的耕耘与劳作。 周光铭院士在接受记者采访时说过这样一句话：“我一生也就做了六台机器。”朋友，你想想，这六台是什么样的机器啊!难道还不够吗?这，就是我们老一代银河人的骄傲!

在研制银河Ⅲ期间，卢锡城同志带领年轻人向新的技术制高点冲击，有11名同志是在攻关战斗中度过新婚蜜月的，不少人连续三次春节都在机房里度过。就是凭着这种精神，他们创造了新的辉煌。这，就是新一代银河人的自豪! 如今，再看看我这身军装，我应该掂得出她的份量。在新的历史时期，我们军队仍然肩负着重大的历史使命。放心吧，祖国，放心吧，人民，时间流逝，斗转星移，永远抹不去的就是战士对党和人民的一颗赤胆忠心!青山和大地会证明我们的忠诚，蓝天和白云会昭示我们的誓言，“奉献”，我们认了，“牺牲”，我们说值!那是因为，共和国军人的心中只有一个期盼，那就是：为了共和国明天的辉煌!
