四大發明作文？四大發明是指中國古代對世界具有很大影響的四種發明。即造紙術、指南針、火藥、活字印刷術。此一說法最早由英國漢學家李約瑟提出并為后來許多中國的歷史學家所繼承，普遍認為這四種發明對中國古代的政治、經濟、文化的發展產生了巨大的推動作用，且這些發明經由各種途徑傳至西方，對世界文明發展史也產生了很大的影響。那我就先說說造紙術，那么，四大發明作文？一起來了解一下吧。
我們中國有世界著名的四大發明，一是火藥，二是造紙術，三是印刷術，四是指南針。這讓我們中國古代成了文明古國。
延續至今，中國的四大發明在各個科技領域中起到了不可替代的重要作用。
一個是火藥，火藥是我們發明的。火藥給我們帶來什么東西呢？帶來了我們的禮花，帶來了我們的鞭炮。到今天為止火藥在我們的歷史上發揮過巨大的作用，通過阿拉伯傳到歐洲之后，歐洲人利用火藥技術制造了大炮，這就是1840年第一次鴉片戰爭和1860年的第二次鴉片戰爭，以及甲午戰爭和1900年的八國聯軍進北京，用中國的火藥燒了中國的圓明園。
說到指南針，我們的鄭和用指南針七下西洋，開拓了中華民族文化進軍世界的先河。他們是傳教士，中國人歷來是善良的，我們下西洋不是為了掠奪，不是為了搶劫。
我們的印刷術，印刷術和造紙術是中國偉大的發明。傳到了歐洲以后，幾百年以后才造福于社會，中華民族熊熊的火炬照亮了西方黑暗的中世紀，他們確實是受益匪淺的。他們的科技發達了，文藝復興了，但是今天我們的造紙術又如何呢？我們的印刷術又如何呢？我們公司有一位對印刷比較精通的副總經理，他每天設計我們公司的產品，我國最好的印刷機叫“海德寶”，是我們發明的活字印刷術，但是現在最好的印刷機是“海德寶”，而四色彩印，精美印刷品，都是人家印的，最好的紙張是人家的，便宜、質量好。
自從四大發明都誕生了，他們的創造者都成了神仙。他們有一個寶物，那個寶物有很強的磁力。但不幸的是寶物被人給盜了。他們便派出了各自的寵物。分別是、指南針、造紙術、印刷術、火藥。它們便走上了尋找寶物的征圖。首先，警犬：指南針聞著寶物的宗跡，一定可以找到盜賊。到了城外，士兵不讓進，這時大汗：火藥把城門炸了。進去卻找不到盜賊，這時，智多星：造紙術把辦法寫在紙上，卻爭的看不來，另一位也現身了沒錯就是印刷術把辦法復制了三份。找到了盜賊，把寶物奪了回來。 回去以后創造者們問：誰起了關建作用？指南針說：是我，要不是我他們跟本找不到盜賊。火藥不滿的說：明明是我，要不是我，他們根本進不了城門。 造紙術生氣地說：要不是我的聰明才智，你們也沒辦法。只有印刷術說：大家不要爭搶，每個人都有功勞。創造者們說：你們要像印刷術一樣謙虛。從此，四大發明成了最好的朋友。

Four Great Inventions of Ancient China -- printing
Block Printing
With the inventions of paper and ink, stamper gradually became popular during the Jin Dynasty (265-420), which was the early form of Carved Type Printing. Block Printing first appeared in the Tang Dynasty (618-907). The text was first written on a piece of thin paper, then glued face down onto a wooden plate. The characters were carved out to make a wood-block printing plate, which was used to print the text. Wood-block printing took a long time as a new block had to be carved for every page in a book.
It took a lot of time and energy as well as materials to prepare for printing a book, but it worked more effectively afterwards. This technology was gradually introduced to Korea, Japan, Vietnam, and the Philippines.
Yet, Block Printing had its drawbacks -- all the boards became useless after the printing was done and a single mistake in carving could ruin the whole block. The frontispiece of the world's oldest surviving book, the Diamond Sutra printed in the year 868, was discovered at Dunhuang Cave, along the Silk Road. The book, in the form of a roll, is the earliest woodcut illustration in a printed book.
Movable Type Printing
Block Printing was a costly and time-consuming process, for each carved block could only be used for a specific page of a particular book, besides, a single mistake in carving could ruin the whole block. However movable type changed all of that.
In the Song Dynasty (960-1279), a man named Bi Sheng carved individual characters on identical pieces of fine clay. Each piece of movable type had on it one Chinese character which was carved in relief on a small block of moistened clay. After the block had been hardened by fire, the type became hard and durable and could be used wherever required. The pieces of movable type could be glued to an iron plate and easily detached from the plate. Each piece of character could be assembled to print a page and then broken up and redistributed as needed. When the printing was finished, the pieces were put away for future use.
By the year1000, paged books in the modern style had replaced scrolls. Two color printing (black and red) was seen as early as 1340.
This technology then spread to Korea, Japan, Vietnam and Europe. Later, German Johann Gutenberg invented movable type made of metal in the 1440s. Movable Type Printing developed very fast. Based on clay type, type made of wood, lead, tin and copper gradually appeared.
Four Great Inventions of Ancient China -- Gunpowder
The invention of gunpowder had a close relationship with the advanced ancient workmanship of smelting industry. People began to know a lot of chemistry knowledge about the nature of different mineral materials during the process of smelting operation. With the knowledge, ancient necromancers tried to seek the elixir of immortality from certain kinds of ores and fuel. Although they failed to get what they were looking for, they discovered that an explosive mixture could be produced by combining sulfur, charcoal, and saltpeter (potassium nitrate). This mixture finally led to the invention of gunpowder although its exact date of invention still remains unknow
Many historical materials indicate that gunpowder first appeared before the Tang Dynasty (618-907). From 300 to 650AD several recipes were written about inflammable mixtures. Some historians date the invention of gunpowder at 850AD when a Taoist book warned of three specific elixir formulas as too dangerous to experiment.
The military applications of gunpowder began in the Tang Dynasty. Explosive bombs filled with gunpowder and fired from catapults were used in wars. During the Song and Yuan dynasties (960-1368), the military applications of gunpowder became common and some other weapons like "fire cannon", "rocket", "missile" and "fireball" were introduced.
In the Yuan Dynasty (1279-1368), the method of powder-making was introduced to the Arab world and Europe, bringing a series of revolutions to weapon manufacturing, as well as to stratagem and tactics on the battlefield. From Italy the making of gunpowder soon spread to other European countries, and by the 1350s it had become an effective weapon on the battlefield.
Four Great Inventions of Ancient China -- Paper
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.
Four Great Inventions of Ancient China -- Compass
Early in the Spring and Autumn Period (770-476BC), while mining ores and melting copper and iron, Chinese people chanced upon a natural magnetite that attracted iron and pointed fixedly north. In the Warring States Period (206BC-23AD), after constant improvement the round compass came into being. Referred to as a "South-pointer", the spoon- or ladle- shaped compass is of magnetic lodestone, and the plate is of Bronze. The circular center represents Heaven, and the square plate represents Earth. The handle of the spoon points south. The spoon is a symbolic representation of the Great Bear. The plate bears Chinese characters which denote the eight main directions of north, north-east, east, etc. This type of compass has been scientifically tested and found to work tolerably well.
By the time of the Tang dynasty (618-907) and the beginning of the Northern Song Dynasty (960-1127), Chinese scholars had devised a way to magnetize iron needles, by rubbing them with magnetite, and then suspending them in water. They also observed that needles cooled from red heat and held in the north-south orientation (the earth's axis) would become magnetic. These more refined needle compasses could then be floated in water (wet compass), placed upon a pointed shaft (dry compass) or suspended from a silk thread, etc. Consequently, they were much more useful for navigation purposes since they were much more portable.
During the Song Dynasty (960-1279) many trading ships were then able to sail as far as Saudi Arabia without getting lost. The compass was introduced to the Arab world and Europe during the Northern Song Dynasty. The spread of the compass to Europe opened the oceans of the world to travel and led to the discovery of the New World.
