我们的地球我们的家园要涉及到我们只有一个地球，地球是不可替代的，如果地球不好了，我们人类也无法生存 Everybody knows that we have only one earth on which we share with different kinds of animals and With the development of the industry，we， the human beings， have produced more and more pollutions whci are harmful to the animals，plants and ourselves as The most serious problem that we have to face is that the earth is being destroyed by our so-called Sometimes，you may find we are having more and more natural disasters on the That is why some countries，like America，has begun to explore the Mars and the other Remember，to save the earth is to save 你看行吗？
Environment protection has become the global However， things like littering and spitting still happen all the As is known， an environment that is surrounded with rubbish， dirty warer， awful air， really does harm to people's We should never stop declaring to save the Since earth is our only place to live， we should dedicate ourselves to protect
Nowadays， the pollution of the Earth has become one of the most serious problems in the It is our duty to save our How can we prevent our earth from polluting? firstly， don not threw garbages at the Because it will pollute the environment and also do harm to your Secondly， donnot let the polluted water get into the Because the polluted water pollute the crops and plants and also will kill a lot of We only have one earth to live on In order to have a better inviroment of living， please try your best to protect

朋友，当你过着快乐祥和的生活的时候，你可曾想到我们的生存环境正一步步的恶化？当你打扫自己的美丽的庭院的时候，你可曾想到我们的周围随处可见的白色垃圾？当你充分享受春日里和煦阳光的时候，可曾想到南极上空已经失去了臭氧层的庇护？曾几何时，天空是那么蓝，河水是那么清，森林是那么密，就在自然环境给予我们美的享受的同时，人类同样在向大自然索取并不应得的东西… …1998年，流经中国大地的长江、嫩江、松花江等大将大河，隐去往日温柔美丽的笑靥，露出了凶猛可怖的狰狞。肆虐的暴雨，横扫着中国的南方和北方，暴雨所到之处，江湖水涨，河沟漫溢。咆哮的江水卷起了一次又一次洪峰，吞噬了一个个村庄，一片片良田，一个个市县，一座座工厂，一所所学校。肆虐的洪水像一只只无情的魔爪，几千万亩良田被淹，几百万人痛失家园。浩浩荡荡的江水，每天都在制造大大小小的险情。暴戾的烘魔，酿造大大小小的险情。暴戾的烘魔，酿造大大小小的悲剧。给水以家园，给万物生灵以家园，人类才会有自己的家园，人类才会有自己的家园；给水以活路，给万物生灵以活路，人类才会能生存和发展。如果说古代科学尚未发达，大地子民们对生态的认识有一定局限，做出了只顾当前不顾长远的蠢事，那么现代人如何呢？自1950年到1980年30年间，全世界有一半以上的森林面积被毁，其中非洲的二分之一林地变成不毛之地。绿色植被是大自然赠于人类的“生命之被”。可是，世界进入20世纪50年之后，人和动物赖以生存的绿色环境遭到破坏，绿色植被正在衰退，全球土壤失量现以增加到每年254 亿吨，沙漠化土壤正以每年5-7万平方公里的速度迅速扩展。地球越来越拥挤，随之而来的是环境污染的日见变化，资源日见匮乏。人们在对幸福的追寻中好梦频惊，不得不回头省视人与自然的关系，与自然签下可持续发展的天人之约，人类的智慧创造了经济的奇迹，无知与贪婪却留下了可怕的恶果。所有的一切无不在提醒着我们：环境保护迫在眉睫！我们生活在同一片土地上，我们拥有着共同家原，保护我们的环境。大地期盼着绿色、河流期盼着绿色、，水鸟期盼着绿色、花儿期盼着绿色。滴水成川，积土成山，保护环境，从你我做起。唤醒“绿色之心”实施“绿色计划”。开展“绿色行动”，争做“绿色建设者，创建“绿色新世纪”！Earth is our only home in If we don't protect it from now on，we will have nowhere to go when the environment being Look at what we have done to our We let out too much exhaust gas that our atmosphere is no longer clear and health for In many big cities，we can hardly see a bright blue We use as much resourse as we can find，then turn them into These rubbish is taken up more and more space in our We also pollute Fishes and other beings are suffering to our Some are died out，Some are dying out in All of us must do something to protect our Take a bus instead of private car;use goods that are made of recycle Many ways we can take in daily life should do good for our better
Like the universe we live inside a slide， a broad speed is relative， as there is an absolute speed， if someone is still running fast， then use the positive direction of the negative throttle， and certainly large， then could return， the volume of the object and the time also there is a relationship， the life span of a decade ants， but they finished the 100 years of human things done， for the ants it is also 100 years， they see the majority of space， is like the Earth and the Earth we see something other than the existence of a volume of absolute time and velocity relationship， if one 100 meters long， it's life-span of 1000， such as the turtle on the speed and life， the universe The one is through， the vast universe， just like human neurons， each connected to the door is not a novel space-time suspect， may be hidden in the Bermuda Triangle， a deep， was formed by the forces of nature， or in the pyramid， the pyramid may be diamond， just not digging Flying is not the dream of the human， material and substance， are all there is absolute， and the stone has links contain CaCO3， and so on， you can say have links to all substances， they also contain more than Quark small matter， if this material can find anti-matter， the same as magnet， then the man will use it flew up into the sky， there is the board hydrogen， hydrogen is a metal plate sheet， the quality is close to 0 or less than 0 ， density greater than titanium， this is not a hypothesis that may later be realized some Light is also a particle， there are quality density， human use of solar energy is the thermal effect of the use of light， convert it into electricity， then use the energy of light particles is infinite， in the more distant future， when the light particles will be replaced H
