作文一百年后的世界【一】
穿越时空，我来到了500年后的地球上。
哇！500年后的地球真不一样。只要是地面，就能看到绿色植被的生机。所有城市的环保别墅与树木共存，为什么叫环保别墅呢？原来别墅所有的建材都是环保的。燃油汽车进了博物馆，路上只有电动汽车、风能汽车和太阳能汽车。地球上没有一个耗天然、不可再生能源的工厂，工厂不排放有污染的废气、废水。再也没有垃圾，垃圾都及时降解了。没有人使用一次性筷子，一次性塑料盒等。
希望地球永远都是这样的，不要变成污水横流、垃圾遍地的地球。
作文一百年后的世界【二】
这部纪录片主要以人类消失后不同的时间段做为线索。人类消失一天后、一个月后、几年后、一百年后、一千年后、以及一万年后的各种不同情形通过3D技术完整地呈现了出来。那些经常依靠人类才能存活的动物，例如狗和猫，又不得不重新认识适者生存这样简单的道理，所以它们就开始找回人类出现之前本来的特性。那些生长在建筑物上的茂密植被不但掩盖了人类曾经建立并且引以为豪的摩天大楼，而且也开始慢慢掩盖人类曾经在这个美丽星球上所犯下的罪行。人类曾经以那些伟大的奇迹为荣。然而，人类从未意识到来自大自然的力量，甚至没有意识到大自然正在通过时间的推移来展现着自己的力量，所以那些摩天大楼犹如大自然中的尘埃，并最终被大自然吞并。
事实上，这样的推断并非没有依据。切尔诺贝利核*漏事故就是一个十分典型的例子，核*漏事故之后的现场情况就如同人类消失后的世界，以致于人们不得不考虑到大自然的力量依然十分强大。如果把地球的46亿年算成一天24小时，目前人类在地球上存活的时间不过只有短短的\'30秒而已。如此说来，人类的历史对于46亿岁的地球来说只能是一篇简短的章节。如今，人类仍然有足够的能力来改造这个星球，这点是毫无疑问的。但是，在人类消失之后，自然界将再次控制地球上的一切。
这部纪录片的真实目的并不寄希望于呈现人类是如何从地球上消失的，只是希望能够阐述一个观点，那就是人类远非我们所想象的那样是这个地球上最伟大的动物。不论我们在地球上曾经创造过多少奇迹、多少成就，在大自然控制的地球上，这些奇迹也将变得毫无任何价值可言。这一切可以为人类可以做为在地球上“到此一游”的证据也将永远被大自然覆盖。
The documentary film that named “Life after People”， which is published by American History Channel， drew my attention in this week。 It can enable everybody to have the introspection on our lives， which is just like many man－made inspirational movies like “Shawshank's Redemption”。 The main difference of this documentary film is that it records the phenomenon that has not happened in the world。 It's just like the imaginary world。 Is this film， it never mentions that how does human disappear， but rather just tries to introspect human's behavior， the concept of civilization， and human's significance in this globe through the background of human's disappearance。
The film wields the time as the link。 Different kinds of scenery of life after people are completely exhibited of one day， one month， several years， one hundred years， one thousand years， and ten thousands years through 3D technology。 Those animals who always depends on human being， especially dog and cat， must reacquire the theory that the fittest can be survived and remind their own original character before people's appearance。 The prosperous greenery growing on the building after people not only mantles those grand skyscrapers that human established and of which they are proud， but also human's sinfulness in this beautiful star can be also gradually blanketed。 People were very proud of their grand miracles that exhibiting in this world。 Nevertheless， they never care about the strong power from nature and even never be award of that the power from nature is encompassed in the movement of time， so those grand skyscrapers and inventions are just several grains of dusts in the nature and it's absolutely inevitable for them to be gobbled up by the nature。
In fact， this kind of fancy is not creating without any foundation。 The example of Chernobyl nuclear disaster is quite similar to the life after people。 We have to respect the power from nature via that disaster。 Human has been in the earth just 30 seconds， if we compress 4。6 billion years as 24 hours。 So it's just a short historic chapter for human to live in this celestial body。 Currently， it is undisputed that human being possesses the colossal power to alter the whole earth。 Nonetheless， nature will dominate everything after human's disappearance from the earth。
The main purpose of this movie is to express a viewpoint， which is that human is not as grand as what we imagine。 No matter how valuable and significant the building or other achievements can be， they are all worthless in the presence of nature after human。 Those so－called miracles during the human's time will be assimilated by nature's strong power and cannot also be proved that human had ever visited the earth for a short while。
