四大发明作文？我们中国有世界著名的四大发明，一是火药，二是造纸术，三是印刷术，四是指南针。这让我们中国古代成了文明古国。延续至今，中国的四大发明在各个科技领域中起到了不可替代的重要作用。一个是火药，火药是我们发明的。那么，四大发明作文？一起来了解一下吧。
自从四大发明都诞生了,他们的创造者都成了神仙.他们有一个宝物,那个宝物有很强的磁力.但不幸的是宝物被人给盗了.他们便派出了各自的宠物.分别是、指南针、造纸术、印刷术、火药.它们便走上了寻找宝物的征图.首先,警犬：指南针闻着宝物的宗迹,一定可以找到盗贼.到了城外,士兵不让进,这时大汗：火药把城门炸了.进去却找不到盗贼,这时,智多星：造纸术把办法写在纸上,却争的看不来,另一位也现身了没错就是印刷术把办法复制了三份.找到了盗贼,把宝物夺了回来.回去以后创造者们问：谁起了关建作用?指南针说：是我,要不是我他们跟本找不到盗贼.火药不满的说：明明是我,要不是我,他们根本进不了城门.造纸术生气地说：要不是我的聪明才智,你们也没办法.只有印刷术说：大家不要争抢,每个人都有功劳.创造者们说：你们要像印刷术一样谦虚.从此,四大发明成了最好的朋友.
四大发明
我们中国有世界著名的四大发明，一是火药，二是造纸术，三是印刷术，四是指南针。这让我们中国古代成了文明古国。
延续至今，中国的四大发明在各个科技领域中起到了不可替代的重要作用。
一个是火药，火药是我们发明的。火药给我们带来什么东西呢？带来了我们的礼花，带来了我们的鞭炮。到今天为止火药在我们的历史上发挥过巨大的作用，通过阿拉伯传到欧洲之后，欧洲人利用火药技术制造了大炮，这就是1840年第一次鸦片战争和1860年的第二次鸦片战争，以及甲午战争和1900年的八国联军进北京，用中国的火药烧了中国的圆明园。
说到指南针，我们的郑和用指南针七下西洋，开拓了中华民族文化进军世界的先河。他们是传教士，中国人历来是善良的，我们下西洋不是为了掠夺，不是为了抢劫。
我们的印刷术，印刷术和造纸术是中国伟大的发明。传到了欧洲以后，几百年以后才造福于社会，中华民族熊熊的火炬照亮了西方黑暗的中世纪，他们确实是受益匪浅的。他们的科技发达了，文艺复兴了，但是今天我们的造纸术又如何呢？我们的印刷术又如何呢？我们公司有一位对印刷比较精通的副总经理，他每天设计我们公司的产品，我国最好的印刷机叫“海德宝”，是我们发明的活字印刷术，但是现在最好的印刷机是“海德宝”，而四色彩印，精美印刷品，都是人家印的，最好的纸张是人家的，便宜、质量好。
China was the first nation who invented paper. The earliest form of paper first appeared in the Western Han Dynasty （206BC-23AD）, but the paper was generally very thick, coarse and uneven in their texture, made from pounded and disintegrated hemp fibers. The paper unearthed in a Han tomb in Gansu Province is by far the earliest existing ancient paper, tracing back to the early Western Han Dynasty.
In the Eastern Han Dynasty （25-220）, a court official named Cai Lun made a new kind of paper from bark, hemp, rags, fishnet, wheat stalks and other materials. It was relatively cheap, light, thin, durable and more suitable for brush writing.
The art of paper-making spread east to Korea and Japan at the beginning of the seventh century （the end of the Sui Dynasty and the beginning of the Tang Dynasty）. In the eighth century, along with the Silk Road, the Arab countries began to learn how to make paper. It took about 400 years for paper to traverse the Arab world to Europe. In the 14th century many paper mills were established in Italy, from where the workmanship of paper-making spread to the European countries such as Germany. The Italians vigorously produced the material and exported large amounts of it, dominating the European market for many years. In the 16th century, the art of paper-making appeared in Russia and Holland, and it spread to Britain in the 17th century.
Before paper was invented, Qin Shihuang, the first emperor in Chinese history, had to go over 120 kilos of official documents written on bamboo or wooden strips. With the invention of paper, the popularization of knowledge has turned into reality. The invention of paper is an epoch-making event in human history
been in lots of diners, and they've always seemed to be warm, busy, friendly, happy places. That's why, on a recent Monday night, I stopped in a diner for a cup of coffee. I was returning home after an all day car trip and needed something to help me make the last forty-five miles. A diner at midnight,however,was not the place I had expected. It was diffhrent, and lonely. My Toyota pulled to a halt in front of the dreary gray aluminum building that looked like an old railroad car. A half-lit neon sign sputtered the message, "Fresh baked goods daily," on the surface of the rain-slick parking lot. Only a half dozen cars and a battered pickup were scattered around the lot. An empty paper coffee cup made a hollow scraping sound as it rolled in small circles on one cement step close to the diner entrance. I pulled hard at the balky glass door, and it hanged shut behind me. The diner was quiet when I entered. As there was no hostess on duty, only the faint odor of stale grease and the dull hum of an empty refrigerated pastry case greeted me. I looked around for a place to sit. The outside walls were lined with empty booths which squatted back to back in their orange vinyl upholstery. On each speckled beige-and-gold table were the usual accessories. The kitchen hid mysteriously behind two swinging metal doors with round windows. I glanced through these windows but could see only a part to the large, apparently deserted cooking area. Facing the kitchen doors was the counter. I approached the length of Formica and slid onto one of the cracked vinyl seats bolted in soldier like straight lines in front of it.
The four great inventionsPaper: paper is an important chemical processes, the invention of paper is Chinese in the spread of human culture and development make a valuable contribution, is China's chemical history of a major achievement.The paper also before, oracle bones, bamboo slips and silk silk is used for writing, the ancient recorded material. But due to the rapid development of the economy, culture, bones and bamboo can not meet the demand of development, thus contributing to the improvement of writing tools. At that time people began using small silk made of paper, as the ancient Chinese when paper by hemp thread and silk, and preparation method of rough paper, so the quality is not so good. But the hemp thread and silk has its own role, to use them as a raw material for paper-making, would be greatly restricted, and difficult to get rapid development, to meet the cultural life of the requirement to paper.In the new situation request, Cai Lun of Eastern Han Dynasty for the emergence of papermaking to bring new breakthrough in the Eastern Han Dynasty," views on" 2 records:" Cai Lun, talented, dedicated to cautious, every vacation, closed to the guest, aeration body field. Code for the sale, made with bark and spacious cloth, net to make paper. Xing Yuan first year playing, the emperor can, since is not used, the salty called Cai Hou paper". From above, Cai Lun is using bark, rags, net of papermaking. Although before Cai Lun also has a paper, but raw material itself is very limited, and Cai Lun on the new raw materials, to solve this problem. Because the rag, broken fishnet had already finished their task, a waste and used as a raw material for papermaking industry, which plays an important role.Printing: is the working people in ancient China through long-term practice and research before the invention of. About the year before and after 600 years of Sui Dynasty, people from the engraved seal inspire 四大发明造纸术:造纸是一项重要的化学工艺，纸的发明是中国在人类文化的传播和发展上所做出的一项十分宝贵的贡献，是中国化学史上的一项重大的成就。
以上就是四大发明作文的全部内容，即造纸术、指南针、火药、活字印刷术。此一说法最早由英国汉学家李约瑟提出并为后来许多中国的历史学家所继承，普遍认为这四种发明对中国古代的政治、经济、文化的发展产生了巨大的推动作用，且这些发明经由各种途径传至西方。
