帮我写一篇“2012世界末日”的演讲稿20分
不会吧，这个看上去不像是一个演讲稿，更像是一个故事，一个话题。
你可讲述一下时间观点，毕竟就剩下最后一天时间了，所以时间是重点
求一篇关于2012世界末日的800字演讲稿（中文的）
2012世界末日这个说法没有科学依据，没有科学依据的演讲就是妖言惑众，蛊惑人心。
何况，玛雅人并不是说2012是世界末日，这只是玛雅人的纪年法，20121221是西方翻译过来的公历纪年。
玛雅人时代的埃及是个古老的文明，自然有自己的纪年法，就好像我国用天干地支来纪年一样。
循环叠加。
现在世界通用公历纪年法，100年就一个世纪，我们活到1999年的时候能说世界要末日了吗
只能说将进入一个新的世纪。
玛雅人所以要记录下来应该是循环的周期不同，就像一个月有28天也有31。
使提前知下月天数。
现在的万年历都记到了2100年
求学生演讲稿（2012世界末日）
一、先来看看关于2012世界末日预言的背景：关于玛雅人：来自美洲古老的玛雅人曾有过非常灿烂的文明。
玛雅人的历法非常神奇, 预言也极为准确。
玛雅人认为我们人类正在经历着一个历时五千多年的星系更新，时间是从公元前3113年起到公元2012年止。
其中每二十年又是一个小周期，从1992年到2012年这二十年是本次太阳纪的最后一个周期，又被叫做“地球更新期”，其间一切都将面临净化和更新，然后人类就将进入新纪元。
关于中国人：与玛雅人不谋而合的是中国古代的传奇般的《推背图》。
推背图第五十二象里的“乾坤再造在角亢”也指出了同一时间。
“乾坤再造”我想大家都明白什么意思吧
而“角亢”呢，指的是传统上的东方青龙七宿，寓指龙年，2012年恰恰是龙年。
关于圣经：最后，是圣经中的最后一部预言，叫做《圣经启示录》（Book of Revelations）。
在所有预言里，圣经启示录可能是对于人类最后的这段时期讲得最准确、最详细的。
其实，整个基督教差不多都是靠先知们预言的不断应验和对神迹的见证来发展的。
我们都知道的“世界末日”和所谓“最后的审判”的说法，其实最终也都是从圣经中来的。
《圣经启示录》描绘了一场规模巨大、代价沉重、无比惨烈、而又波澜壮阔的正邪较量和人类劫难。
因为时间的关系，这里只能概括的描述一下。
《圣经启示录》描述了一场由一个被称做“羔羊”（也就是小羊羔的那个羔羊）的人和他的信众与被称作“兽”（也就是野兽的兽）的势力之间所发生的激烈较量。
《启示录》中明确指出“他们与羔羊争战，羔羊必胜过他们，因为羔羊是万主之主、万王之王”，“他的名称为神之道”。
当然，由于许多人都受到了“兽”的迷惑，助纣为虐，犯下了大罪，所以人类会经历巨大的灾难。
《启示录》中提到了包括规模空前的火灾、地震、冰雹、烟雾和硫磺（可能指火山爆发
）、蝗虫、瘟疫、异常的高温与战争，水变质害死人，海中生物的大量死亡等等等等。
本来这些灾难是惩戒人们不可作恶，要人们马上悔改其罪恶的，但《启示录》中也预见到了：许多人还是不但不悔改，反而因为自己受到的灾难与痛苦而更加怨恨和亵渎神灵。
当然，最终羔羊和圣徒们战胜了邪灵怪兽，之后是所有的罪人都会经历“最后的审判”而受到彻底毁灭性的惩罚。
而后，人类会进入一个新天新地、空前美好的太平盛世。
《启示录》很长，讲得也很玄，完全象是神话故事，但末了，却非常的肯定和严肃，告诫人们这是真实的，是一定会发生的。

December 21 2012.Fire pours down from the sky, ocean bumps and swallows the land, earthquake rips ground into parts. People who believe the dooms say the December 21 2012 is the end of the world. They can expect billions of people to die, it is going to be the most terrible on our plant, Mother Nature is going to be a scary executioner to kill everything, this is when and how the world will end. If you believe in the predictions, so our plant has a great bull eye on it and any number of darts are going to hit us around year 2012, but the question is: is any of that going to happen? What are 2012’s most plausible planetary disasters? And is the end of life on earth looking just right around the corner? On Friday, December 21, 2012, the sun will rise as usual, but on this day, it will align itself just between the earth and the center of our galaxy. And the end of the world is coming. There are people who believe that some huge changes will befall the earth or humanity, that the god will press a great button of ‘off’ in the sky, by the end of the day, the world will be blanketed in ash, once busy city streets will churn with rivers of lava, massive earthquakes will have bought tall cities crashing to the ground, and enormous oceans waves will be rushing in to wash us away. It is just one version of an apocalypse that expect to see in our lifetimes, Some people believe this coincides with the sun eclipses the center of the Milky way, when it does, they say we will be cut off from the vital cosmic energy emanating by the black hole as the heart of the center of our galaxy. Some people believe the life on earth will be thrown into upheaval or wiped away. And there also are some people disagree. They say there is no any kind of energy that can be blocked from our galaxy. In fact the alignment had happened in 1999 and the world didn’t be end, so there is on any particular reason that can be making us to believe that the alignment in 2012 will bring any difference. Why are many people convinced that the end of world will happen at one day not other days, and precisely this day is December 21, 2012? Why people say December 21 2012 is the doom day? It is because the Mayan Calendar says December 21, 2012 is the apocalyptic day. Mayan is extremely good at mathematic and astronomy. The longest calendar that has been count by Mayan is for 5126 years. Experts believe that the current Long Count probably began in 3114 B.C. and will end on December 21, 2012. But there is one thing that would happen in 2012, that is magnetic blast from the sun. Every 11 years, the sun reaches the maximum level of activity, and it can averagely fire off 2 or 3 Solar Flare every single day, and the end of 2012 is expected to be getting itself ready to enter the next solar maximum, and unfortunately even our scientists are not sure what is the next Solar Flare will be like, it may gave us some surprises in 2012. So what is going to happen if it does gave us some surprises in 2012? The consequences could be much more far than any disasters that had happened to us. The Solar Flares are massive explosions of great energy, and it is like millions of hydrogen bombs explode all at same time, but as powerful these explosions of radiation are, it is sometimes just the beginning of a solar temper-tantrum. After that, there also is material that is rushing out from the sun is called ‘Coronal Mass Ejections’. It will be pushed away with billions of billions of ton hot gas, and it travels at speeds of a millions or so miles per hour. The environment around the sun is filled with the Solar wind that the particles of the sun’s atmosphere that are streaming away, then the CME (Coronal Mass Ejections) goes into this material and creates a shock wave, and the shock accelerates the particles that are in front of the CME. So if it comes to our direction, we will get in a really big trouble. If the sun fries one at us in 2012, you will not have much time to prepare for it, even if you see it coming, because the bulk of the CME will reach us in just a few days, their speed is almost reaching to the speed of light. So what will happen when the particles reach earth? Firstly, the shock wave of energized particles will slam into our satellites orbit, shouting out their electronics to block our satellites networks, so imagine what will this be like? 1 The GPS on every vehicle will be broken. It will make airplanes crashing, steamboats getting in lost. But losing the satellites networks could be just a beginning of the real bad day. Once the shock wave has been passed, the bulk of CME will crash into the earth’s magnetic field. The Earth’s Magnetic field is a kind of power that shields us from the CME attacking. This natural barrier normally prevents charged the particle form reaching the surface by deflecting them around the earth, but as the CME is strong enough, it will make a high damage to our natural barrier. When charged particles from solar storm hit the magnetic field which also called magnetosphere, they can become trapped in this field, and we can see this phenomenon as aurora, or as northern lights, but if you see them in your neighborhood, it means an imminent disaster is coming. If the charged particles are too many that even the magnetosphere can’t be tolerable, it causes a moving of our magnetic field, and that, in turn, will cause electric currents on the ground, and these currents can cause fluctuations, and transformers to be shorted out. This would bring down the power grid and cause blackouts. So if we have been hit by a solar blast that powerful enough, our cascading failures in power system could fry the electric grid the world over. According to a recent report issued by the National Academy of Sciences, full recovery could take 4 to 10 years. If it really does happened, the consequences could be devastating, the food is going to run out, people could be dead of freezing, suddenly people would not have water for drinking, or for agriculture, or for sewage. Modern civilization will be hurled back into a literal dark age, and the result could be anarchy. But actually it only gets worse from here. As a moving of the magnetic field, it causes our land moving around, and getting lots of huge crashes between land and land. As it is crashing, earthquakes, volcanic eruptions, tsunamis, and Lava Rivers would come for destroying us, for wiping us out. But that doesn’t mean humanity has to just sit around and wait for the sun to chat and blister the world that we have made. There is lot we can do to prepare for something like this. We can do lots of things with the power grids. You basically turn them off or turn them down, and something like this. But everything that mentioned is just the predictions from our scientists, and the likelihood of that will happen in 2012 is low and from lots of more report and researching, the likelihood is getting lower. But it is not meaning that it is not going to happen forever, it means it is not going to happen in 2012, but soon. 还有就是希望你有一个好的成绩。
