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

(來源：英語麥當(dāng)勞004km.cn)

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.(來源：英語麥當(dāng)勞http://004km.cn)

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.

Hello everyone.Today I’m going to talk about the Four Great Inventions of the Ancient China.Do you know their name in English? If you don’t, let me introduce to you.Papermaking technology During the Eastern Han Dynasty, Cai Lun summed up the experience of forefathers, began to improve papermaking technology.He used a lot of simple things and produced the ‘Cai Hou’ paper.This kind of paper is thin and can write easily.He made enormous contribution for China.It was produced to other countries after about 500 years.Typography Typography is a kind of printing.Before printing was invented, people had to record information by writing or other ways.But it always took a lot of time.Then Bi Sheng invented typography and improved the printing technology.It began to take less time and become easy to record information.It’s a great achievement in the history.Compass

It was invented in the Warring States.After people found that a magnet could give directions, the compass was invented.It was a magnet made into a shape of spoon.When it stops, the spoon can point to the south.Then, it was produced to Europe in the 13th century.Not everywhere has a lighthouse, so a compass is very useful for sailing.Even at a new place people will not lose their way with a compass.Gunpowder Gunpowder is also called black powder.It was invented in Tang Dynasty, about 9th century.It began to be used in military affairs and made great contribution for China.Guns, aircrafts could be invented afterwards.Papermaking technology, typography, compass and gunpowder are Four Great Inventions of the Ancient China.They have made great contributions for people all over the world.As a Chinese person, we should remember and be proud of them.That’s all for my duty.Thank you for listening.1.sum

第四篇：四大發(fā)明感想

我一直在思考，中國是一個(gè)有悠久歷史的文明古國，在千余年前（宋朝以期），中國曾是一個(gè)傲視世界的東方帝國，無論是文化、經(jīng)濟(jì)還是軍事，在當(dāng)時(shí)都是傲視群雄，位于世界之顛。為什么中國自漢唐以后說不行就不行了。難道中國差了什么？最近似乎想明白了，中國不是少了什么，而是多了一些東西。正是多了這些東西，成了中國高速前進(jìn)的阻礙和羈絆。我們沒有從老祖宗那里收益，反而受害。

關(guān)于“四大發(fā)明”的議論，我聽過很多。最初是一味地引以為豪，對(duì)老祖宗頂禮膜拜；后來魯迅先生對(duì)這種“我們古已有之”的“阿Q”心態(tài)進(jìn)行了無情地批判，底氣就顯得不足了，心有戚戚焉，也學(xué)著先生罵起國民劣根性來了；再后來有人提出“新四大發(fā)明”、“第五大發(fā)明”的觀點(diǎn)，企圖變著法兒光宗耀祖，其實(shí)也就是落后挨打的委屈憋得太久了，以此來出口“阿Q氣”。如果細(xì)讀一下科學(xué)史，我們也許能從“四大發(fā)明”的爭(zhēng)議中讀出許多意味來。

“四大發(fā)明”這種說法起源于何時(shí)，出自何人，可能難以考證。最通行的說法是哲學(xué)大師叔本華提出的；也有人說叔本華之前，西方人已經(jīng)津津樂道于中國的四大發(fā)明了。不管怎樣，有一點(diǎn)是可以肯定的：四大發(fā)明的說法不是中國人提出來的。

歐洲人之所以認(rèn)可這四大發(fā)明，是因?yàn)檫@四項(xiàng)發(fā)明是促成歐洲文藝復(fù)興運(yùn)動(dòng)的重要的科技前提之一，而中國人自己，對(duì)這些成果的利用是非常有限的——當(dāng)然，在一個(gè)把科技與雜耍、倡優(yōu)并列為“百工”的時(shí)代，中國人幾乎還沒有科學(xué)的自覺要求。

指南針在西方引發(fā)了航海革命，殖民者因此才得以遠(yuǎn)征全球。正是在指南針的指引下，西方列強(qiáng)發(fā)現(xiàn)了中國這塊肥肉。但在作為發(fā)明者的中國，羅盤主要被風(fēng)水先生用來尋穴看地——雖然，我們的歷史上也出現(xiàn)過鄭和下西洋的盛事，但這一航海壯舉并沒有給民族振興產(chǎn)生太大的影響。

火藥經(jīng)阿拉伯傳到西方后，引起軍事上的革命，歐洲資產(chǎn)階級(jí)就是利用火器擊敗封建騎士軍隊(duì)并迅速向外擴(kuò)張的。最后，列強(qiáng)用中國人自己發(fā)明的火藥轟開了中國的大門，從而開始了100多年的屈辱史。在中國，火藥的最大效用是制成煙花炮仗用于紅白喜事。當(dāng)殖民者憑借槍炮在中華大地上瘋狂屠殺搶掠的時(shí)候，我們還把那種噴射出火藥的武器稱為“妖術(shù)”。如果一定要說指南針、火藥對(duì)中國的貢獻(xiàn)的話，那就是客觀上使我們蒙受恥辱的時(shí)候同時(shí)也結(jié)束了閉關(guān)鎖國。

中世紀(jì)的歐洲普遍以昂貴的羊皮作為書寫材料，除了少數(shù)貴族，普通人無法接受正規(guī)的教育。中國的造紙術(shù)、印刷術(shù)傳到歐洲后，很快促成了歐洲文化、教育領(lǐng)域的革命。紙質(zhì)書籍的大量印刷，使廣大人民有了受教育的機(jī)會(huì)，歐洲的國民素質(zhì)得到大幅提高。與此形成鮮明反差的是，造紙術(shù)、活字印刷術(shù)發(fā)明之后，中國人首先想到的是印刷《金剛經(jīng)》，它們?cè)谥袊鴼v史上的影響也是極其有限的。

中國的四項(xiàng)科技發(fā)明為歐洲文藝復(fù)興運(yùn)動(dòng)的興起做出了重大貢獻(xiàn)，被尊為“四大發(fā)明”是理所當(dāng)然的。所謂“四大發(fā)明”，其實(shí)是西方人的“四大”，中國人的“發(fā)明”。這就是科學(xué)史給我們的啟示。

細(xì)讀科學(xué)史，中國人還會(huì)產(chǎn)生許多隱痛。我們?cè)?jīng)夸耀：中國是是人類歷史上科技領(lǐng)先時(shí)間最長(zhǎng)的文明古國；但是從數(shù)量上分析，整個(gè)人類古代史的科技成果總量是及其微小的，毫不夸張地說，現(xiàn)代世界一年的科學(xué)發(fā)明數(shù)量就超過古代幾千年科技發(fā)明的總和。以此推算，中國古代的科技發(fā)明相對(duì)于人類科技總量來說幾乎可以忽略不計(jì)，想想看：我們所看到的東西——小到螺釘紐扣，大到飛機(jī)輪船，有幾樣?xùn)|西原創(chuàng)自我們古老的中國？這就難怪西方的許多科學(xué)史著作很少提到中國，甚至否認(rèn)中國出現(xiàn)過系統(tǒng)的科學(xué)技術(shù)了。

其實(shí)我們不必過于計(jì)較西方科學(xué)史對(duì)我們的偏見，文藝復(fù)興以來，西方科學(xué)技術(shù)突飛猛進(jìn)，中華民族卻裹足不前，這是鐵的事實(shí)。從近代天文學(xué)沖破神學(xué)桎梏開始，西方人創(chuàng)造了人類最輝煌的科學(xué)成果：牛頓力學(xué)、達(dá)爾文進(jìn)化論、量子力學(xué)、相對(duì)論、電的發(fā)明及應(yīng)用、生物工程技術(shù)、電腦技術(shù)、航天技術(shù)??一大批偉大的科學(xué)家用他們的智慧照亮了人類的歷史，在這樣的事實(shí)面前，中國人哪有沾沾自喜的理由？

我想，從科學(xué)史中讀出隱痛比阿Q式的自得要有益得多。如果一定要光宗耀祖，那就先把四大發(fā)明放到一邊，整出幾個(gè)五大發(fā)明、六大發(fā)明再說，要不，生活在離開西方人發(fā)明的物品就無法生活的現(xiàn)代社會(huì)里，拿四大發(fā)明說事實(shí)在不夠分量。

中國至少有五千年的歷史，也就是說中國起跑很早，中國有充足的時(shí)間來發(fā)展。中國有光輝燦爛文化，中國早在數(shù)千年前就位于世界之顛。中華民族的祖先們給他們的后人留下了豐富的遺產(chǎn)：雄厚的物質(zhì)基礎(chǔ)和數(shù)不清的創(chuàng)造發(fā)明。所以說雖然現(xiàn)在還有很多不如人意的地方，但是經(jīng)過我們現(xiàn)代人不斷努力，中國的未來還是很有發(fā)展的！

第五篇：四大發(fā)明教案

《四大發(fā)明的貢獻(xiàn)》教學(xué)設(shè)計(jì)

一、創(chuàng)設(shè)情境，導(dǎo)入新課 1.播放視頻

同學(xué)們，2008年8月8日，舉世矚目的第二十九屆奧運(yùn)會(huì)在中國北京隆重舉行。今天，讓我們一起再去重溫奧運(yùn)會(huì)開幕式那些美麗的畫面！

師：第二十九屆奧運(yùn)會(huì)開幕式的這些畫面給世界展示了什么主題，你知道嗎？（四大發(fā)明）

問：中國古代四大發(fā)明都是什么呢？點(diǎn)擊課件 造紙術(shù) 印刷術(shù) 火藥 指南針 師：這節(jié)課我們就來學(xué)習(xí)第三課祖先的科學(xué)技術(shù)成就。一起探究我國四大發(fā)明對(duì)整個(gè)世界的貢獻(xiàn)。

二、學(xué)習(xí)新知 造紙術(shù)：

1.紙張?jiān)谏钪卸加惺裁从猛荆?/p>

用來制造紙箱等工業(yè)用紙。制造紙袋、購物袋的包裝用紙。衛(wèi)生紙、餐巾紙、紙巾、醫(yī)療用紙等家庭用紙。辦公室等打印用紙。還有棉紙、宣紙、鈔票紙等。用途非常廣泛，如果沒有了這些紙，我們的生活很難想象。2.在紙產(chǎn)生之前，人類的書寫材料？ 主要有甲骨、絲帛、竹簡(jiǎn)等，上述書寫材料有什么缺點(diǎn)？

缺點(diǎn)：書寫比較麻煩，不易攜帶、價(jià)格昂貴

當(dāng)時(shí)發(fā)生了不少有趣的故事。學(xué)富五車這個(gè)成語故事就是其中的一個(gè)。我們來看。3.講故事：

西漢東方朔用竹簡(jiǎn)寫奏章，因?yàn)橛袧M肚子的話要說，一下子就用了3000來根竹簡(jiǎn)。東方朔手無縛雞之力，無法拿動(dòng)這么龐大的奏章，最后只好請(qǐng)了兩位大力士抬進(jìn)宮里去。據(jù)《史記·滑稽列傳》說，漢武帝花了兩個(gè)月的時(shí)間才看完那一大堆竹簡(jiǎn)。

戰(zhàn)國思想家惠施，人稱博學(xué)多才、學(xué)富五車。原來，他旅行時(shí)也愛學(xué)習(xí)，隨車裝著愛看的書。這些書是一捆一捆的竹簡(jiǎn)和木牘，一共裝了5輛車，“學(xué)富五車”的成語就是這么來的。算一下，五車書能有多少字？ 蔡倫與造紙術(shù)、教師引導(dǎo)：點(diǎn)擊課件：蔡倫像，這就是蔡倫像。

過渡語：到底紙是如何發(fā)明的？請(qǐng)聽我給大家講蔡倫與造紙術(shù)

思考：蔡倫使用什么材料造紙？造紙的主要步驟？ 問：為什么說“蔡倫造的紙得到了推廣？”

（學(xué)生談感受?！獦淦ぁ⒙槿~、破布、破漁網(wǎng)等。教師引導(dǎo)：材料便宜，哪兒都有，都用得起，而且輕便。）

師：剛剛xx給大家介紹了蔡倫和改進(jìn)造紙術(shù)的過程。這就是蔡倫像。在蔡倫改進(jìn)造紙術(shù)之前，已經(jīng)出現(xiàn)了早期的紙呢？什么時(shí)期？（西漢）課件點(diǎn)擊：西漢的紙

教師小結(jié)：中國造紙術(shù)比歐洲早了1000多年，從中我們也感受到了我國古代勞動(dòng)人民的聰明才智

過渡：在造紙術(shù)出現(xiàn)后，又出現(xiàn)了一項(xiàng)新的技術(shù)，它是？——印刷術(shù) 印刷術(shù)：

這兩幅都是古代雕版印刷品。哪個(gè)是雕版印刷，哪個(gè)是活字印刷？

師：印刷術(shù)中有雕版印刷和活字印刷兩個(gè)重要的階段。雕版印刷和活字印刷的過程游什么區(qū)別呢？視頻 2.介紹雕版印刷和活字印刷

生：雕版印刷的過程主要是把要用的所有的字都反刻在木板上，然后印刷。活字印刷則是把一個(gè)一個(gè)的字分別反刻在木板上，需要哪些字就組合哪些字，然后再印刷。

教師出示課件雕版印刷和活字印刷的過程，讓學(xué)生更準(zhǔn)確了解雕版印刷和活字印刷的過程。

過渡：印刷術(shù)的發(fā)明，有一個(gè)重要的人物，大家知道他是誰嗎？（畢昇）4.活字印刷術(shù)是怎樣傳向世界的？

我國的活字印刷14世紀(jì)傳到朝鮮、日本以及埃及后來傳入歐洲。（點(diǎn)擊課件）指南針：

1.指南針的發(fā)展變化過程。指南針不斷改進(jìn)的流程圖。司南（戰(zhàn)國）—指南魚（北宋）—縷懸法指南針、元代支承龜----水浮法指南針-----清代旱羅盤（教師課件出示）

2、司南由青銅地盤與磁勺組成。地盤內(nèi)圓外方，中心圓面下凹；圓外盤面分層次鑄有10天干、十二地支、四卦，標(biāo)示24個(gè)方位。磁勺是用天然磁體磨成，置于地盤中心圓內(nèi)，勺頭為N，勺尾為S，靜止時(shí)，因地磁作用，勺尾指向南方。

3.指南針又給社會(huì)帶來了哪些變化呢？

指南針的發(fā)明推動(dòng)了航海業(yè)的發(fā)展，指南針在航海中成為船員們不可缺少的“眼

睛”。在航海業(yè)非常不發(fā)達(dá)的時(shí)期，人們很難知道在自己國家以外的地方是什么，或是海的那一邊是什么。

問：為什么說指南針是航海家的眼睛？（辨別方向）課件點(diǎn)擊，介紹三位航海家。

鄭和：明成祖朱棣時(shí)期,中國古代規(guī)模最大、船只最多（240多艘）、海員最多、時(shí)間最久的海上航行，比歐洲國家航海時(shí)間早幾十年?？胺Q是“大航海時(shí)代”的先驅(qū)，是唯一的東方人，更有說法稱鄭和最早發(fā)現(xiàn)美洲、澳洲、南極洲。哥倫布：1492年，意大利航海家，先后4次出海遠(yuǎn)航發(fā)現(xiàn)了美洲大陸，開辟了橫渡大西洋到美洲的航路，證明了大地球形說的正確性。

麥哲倫：1480年生于葡萄牙北部的 一個(gè)破落的騎士家庭。16歲時(shí)進(jìn)入葡萄牙國家航海事務(wù)廳，因而熟悉了航海事務(wù)的各項(xiàng)工作。麥哲倫環(huán)球航行是世界航海史上的一大成就，不僅開辟了新航線，還通過他的探險(xiǎn)船隊(duì)進(jìn)行的探險(xiǎn)航行證明了地球是圓的，地球是個(gè)圓球。

師：航海家在航海的過程中，指南針起到了非常重要的作用。

師：今天，給大家?guī)砹藥讉€(gè)指南針，先請(qǐng)一個(gè)同學(xué)給大家介紹一下指南針。3.指南針演示

師：我們?cè)谥婪较虻臅r(shí)候，不能感受到指南針的重要，如果我們迷路了，才真的能夠體會(huì)指南針的重要。感興趣的同學(xué)，回家可以買個(gè)指南針玩一玩，如果我們出去旅游，還能用上。4.指南針發(fā)展到什么程度

師：指南針發(fā)展到什么程度了呢？gps導(dǎo)航系統(tǒng)。火藥：

火藥的起源和發(fā)展

火藥是中國在7、8世紀(jì)發(fā)明的，古代煉丹家制藥時(shí)，逐漸發(fā)現(xiàn)硫黃、焰硝和木炭的混合物有燃燒和爆炸能力。點(diǎn)擊課件

大約在9世紀(jì)用于軍事。唐末在戰(zhàn)爭(zhēng)中開始出現(xiàn)火藥箭,還有火藥包，作燃燒性兵器。宋朝東京開封府有生產(chǎn)火藥的部門。宋神宗時(shí)，邊防軍中已大量配備火藥弓箭、火炮箭等兵器。

課件點(diǎn)擊：老師帶你們欣賞一些古代的火藥武器：

2.火藥是怎樣傳向世界的？恩格斯《德國農(nóng)民戰(zhàn)爭(zhēng)》中說：“火藥是從中國經(jīng)印度傳到阿拉伯，又由阿拉伯人和火藥武器一道經(jīng)過西班牙傳入歐洲”。

3.在重大節(jié)日中，人們會(huì)使用焰火來慶祝。同時(shí)火藥應(yīng)用到生產(chǎn)與勞動(dòng)中，大大提高了效率。

三、情感升華：
