发明类的演讲稿篇2

在浩瀚的历史长河中，中华民族五千年历史，书写着永不停息、对美好幸福的追求，展示着永不磨灭、对民主富强的探寻。我们知道中华民族古代有四大发明，现在有“新四大发明”

古代四大发明我们耳熟能详，但新四大发明是什么呢?新四大发明是今年高考一卷作文中提到的：高铁、支付宝、共享单车和网购。那问题又来了?为何这四样能和古代四大发明相提并论呢?答案只有一个：这是由外国人投票得出的结果，因此说明他们对世界的影响不亚于古代四大发明。

古代四大发明在几百年以前传到世界各地，不同程度上影响了各国文明进程，以活字印刷为例：毕昇在十一世纪中叶完成了此举，而西方国家却在400年后才发明了此项技术，这不能不说古人的伟大。而“新四大发明”如同刚刚萌发的幼苗，却可以吸引各国人的眼球，让外国人强烈要求这些东西能发展到自己的国家。这背后不是什么大国策略，而是“新四大发明”能真正的服务生活，征服了所有人。

“新四大发明”中占主导位置的我想莫过于支付宝了吧，不论是网购还是共享单车，支付宝都是首选的支付方式，就连高铁的车票也是如此。最关键的一点是，支付宝的信用机制。在现在乃至未来，信用将极大程度的决定你的生活，信用越高，越能享受高质量服务，共享单车的押金免付，蚂蚁花呗透支提现，租借日常用品等等开创了先河，这是微信等支付宝的竞争者完全不能比的。

网购是近十年开始兴起的，但其创作的价值却是可以撑起一个小国而且还方便了人们的生活，随时随地购买自己想要的商品还不受国界的限制。正如网上流行的一句话所言“只有你想不到，没有你买不到”。

至于高铁和共享单车已经成了中国的一张名片，因中国高铁技术不亚于甚至优于国际水平，比如列车飞速行驶，硬币却始终立得稳稳的，让世人惊叹。共享单车则因为新颖的出行方式博得了老外的眼球，虽然问题频出，但还是有很大的发展空间，毕竟“最后一公里”的问题除了共享单车没有什么更好的方法了。

从指南针、造纸术，到“新四大发明”移动支付、共享单车、高铁和电子商务，中国已经从实体发明跨越到虚拟世界创新。俗话说：“当变革之风吹起，有人修建高墙，有人则修建风车。”我知道，对于未来变革之风感到兴奋的，不止我一个。

what is my favorite invention?

we knew there had been many inventions at the last century, for example, electric light bulb, telephone, phonograph, mimeograph machine, automobile, airplane, atomic weapon, computer and so on. what is my favorite invention?

personally, my favorite invention should be computer. in the old days, many scientists took much time to calculate and deal with research data, so the effective time in doing research was relatively shortened. for millions of times of calculating per second by computer, the researchers may have enough time to study more important issues. the processing of experiment results became very simple and easy. aren’t those all evidences that the computer is one of the greatest inventions in the last century, are those?

发明类的演讲稿篇4

阖上手中的书本，脑海里依然徘徊着书中隽永的话语，抬起头来，看看眼前这数以万计的书本摆满了书架，在这偌大的图书馆里，不知收藏了多少古今中外智者苦心钻研的成果、人类智慧的结晶，究竟是何等的“魔法”，得以将世界各国不论文学、科技、天文、地理、经济、历史等等知识全网罗在这名为“图书馆”的建筑物里?是“印刷术”!是印刷术这项伟大的发明，使人类文化的传播与传承起了划时代的巨大转变与影响，因此，在我心目中，生活里最伟大的发明非“印刷术”莫属了!

印刷术是中国古代四大发明之一。在印刷术发明之前，知识的传播仅能靠口耳相传或手抄。口耳相传容易造成讹误，而手抄既费时、费事，又容易抄错、抄漏，因此知识的保存与流传相当不容易，如此不仅阻碍了文化的发展，更使文化的传播遭受延宕及损失。直到隋朝开始有了雕版印刷，至宋仁宗时，有个叫毕升的刻字工人，他用质地较细且带有粘性的胶泥做成四方长柱体，并在其上刻了反写的字，一个印一个字，放进土窑里烧，制成活字，然后再依文章内容依序排列文字，做成印刷版，这就是活字印刷术的发明。此种印刷术方法虽然原始简单，但已与现代铅字排版印刷原理相同，之后中国又出现了木活字、金属活字和泥活字，使印刷术愈来愈进步。

有了印刷术，人类的知识、经验、着作、历史等等得以更广泛、更正确的被保存下来，不致因为手抄的困境而谬误或失传，对于知识的传承发挥了绝大的功效，于是人类得以在前人的着作中得到知识、经验的传授与启发，累积前人的研究成果，继续发扬光大，因此印刷术成为人类文化得以承先启后的大功臣，是促使文化跃进的一大助力。并且活字版的发明和发展，使人类得以享受方便、迅速、较低成本的书籍及印刷产品，透过大量印刷复制的过程，使知识可以大量的流传，而透过这些人类智慧结晶的广为流传，促使文化的交流更为普遍而频繁;并因为知识、书籍的取得更容易，使一般大众都有机会受教育，知识书本将不再只是少数权贵人士的权利，加速了知识教育的普及，对人类文明的演进产生了重大而深远的影响。因此中国印刷术的发明，可说为人类文化划亮黎明的曙光，为文化的广泛传播、交流与传承创造了前所未有的条件。

而印刷术的发明之所以堪称“伟大”，乃因它的影响力并不局限于中国，而是全球性的，对于全人类的文化发展皆产生了推波助澜的效益，根据史书的记载，中国的雕版印刷技术在公元八世纪传入了日本和北韩，木活字技术则大约于十四世纪传入北韩、日本，后又从新疆经波斯、埃及传入欧洲。使欧洲中世纪的科学从漫长黑夜之后继之以突飞猛进的发展，以及为文艺复兴运动的出现提供了一个重要的物质条件。因此印刷术的发明，可谓对于全人类的文化做出了伟大的贡献。

弗朗西斯培根(francisbacon)在《新工具》一书中曾说：“我们应该注意各种发明的威力、效能和后果。最显着的例子便是印刷术、火药和指南针。这三种发明曾改变了整个世界事物的面貌和状态，第一种在学术上，第二种在军事上，第三种在航海上，由此又产生了无数的变化。这种变化是如此之大，以致没有一个帝国、没有一个教派、没有一个赫赫有名的人物，能比这三种机械发明在人类的事业中产生更大的力量和影响。”诚如所言，印刷术对于世界知识的传播、文明的演进，具有极其重要而深远的影响。如果没有印刷术的发明，至今人类文化可能仍在封闭而错误百出的漫漫长夜里跌跌撞撞，知识的传播受阻，现代文明亦将会延迟几百年出现，那么世界就不会是现在这种繁荣的局面了。

如今我们得以享有印刷术这项伟大发明所带来的丰硕知识、昌盛文明等成果，在心存感激之余，更应善加珍惜、充分利用这些资源，怀抱梦想，在前人呕心沥血的智慧成果中自我惕励，期盼精益求精，将人类文明继续向前推进。

in the early nineteenth century, people began to use gas (gaslight), but the gas pipeline supply by a leak or blockage, very easy to have an accident, people for illumination of reform, very ardent.in fact, edison for himself set the mission impossible: in addition to improve lighting, but also of thomas edison electric light create a set of power supply system.and he and the dream luoyuan buddies, sleepless do 1600 repeatedly heat-resistant material and more than 600 plant fiber experiment, only produced the first carbon wire bulb, can a burning 45 hours.later he more on this basis, the method of continuous improvement manufacture can ignite 12 hours finally came out with the zhusi bulbs.the 19th century the 1980s, edison electric light career succeeded, this success than any previous achievements brought him reputation.in the 1980s, before he had little mistake, intermediate later, although he has made great achievements, but also common occurance of failure.edison's most not commendable actions is one of his criticism alternating current, say it has side effects, likely cause of death and injury, but he did not add details.so somebody said, "as he such a mess out many inventions that people about others' new invention saurday attack, this is very contradictory things." he opposes the use of alternating current and direct current, so the approve a fierce debate and stubborn in failure.in this respect, reflects the edison became a celebrity after the stubbornness of started to foster old-fashioned shortcomings.

发明类的演讲稿篇6

i have a dream that one day every vally shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the lord shall be revealed, and all flesh shall see it together.

wow, what a dream it has been for martin luther king. but the changing world seems telling me that people gradually get their dreams lost somehow in the process of growing up, and sometimes i personally find myself saying goodbye unconsciously to those distant childhood dreams.

however, we meed dreams. they nourish our spirit; they represent possibility even when we are dragged down by reality. they keep us going. most successful people are dreamers as well as ordinary people who are not afraid to think big and dare to be great. when we were little kids, we all dreamed of doing something big and splashy, something significant. now what we need to do is to maintain them, refresh them and turn them into reality. however, the toughest part is that we often have no ideas how to translate these dreams into actions. well, just start with concrete objectives and stick to it. donsquo;t let the nameless fear confuse the eye and confound our strong belief of future. through our talents, through our wits, through our endurance and through our creativity, we will make it.

hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. hold fast to dreams, for when dreams go, life is a barren field frozen with snow. so my dear friends, think of your old and maybe dead dreams. whatever it is, pick it up and make it alive from today.
