❺ 中国现代四大发明英文介绍

中国现代四大发明一般指新四大发明，所谓“新四大发明“是指“高铁、扫码支付、共享单车和网购”。2017年5月，来自“一带一路”沿线的20国青年评选出了“中国的新四大发明”：高铁、扫码支付、共享单车和网购。

1、High-speed rail

On October 1, 1964, Tokaido Shinkansen Line was officially opened to traffic. The operation speed is as high as 210 km/h. So the first real high-speed railway in the world was invented by Japan. This marks the arrival of a new era of high-speed railway in the world.

As a pioneer of high-speed railway in the world, Japan has accumulated rich experience for other countries, including China, which have not yet developed or are developing high-speed railway, and transferred some technology to these countries to help them develop high-speed railway system faster and more conveniently.

In March 2006, the CRH2A train Retrofitted from E2 series 1000 sets sailed from Kobe Port to Qing, China, and transferred some technology to China, thus ushering in the era of high-speed railway in China.

中文翻译：

1、高铁

1964年10月1日，日本东海道新干线正式通车。运营速度高达210公里/小时。故世界上第一条真正意义上的高速铁路由日本发明。这标志着世界高速铁路新纪元的到来。

日本作为世界高速铁路的先驱为包括中国在内的其他尚未或正在发展高速铁路的国家积累了丰富的经验，并有偿转让了部分技术予这些国家，以帮助其更快、更方便地发展高速铁路系统。

2006年3月，由E2系1000番台改造而来的CRH2A型列车从神户港装船出发前往中国青岛，并转让部分技术予中国，由此开启了中国的高铁时代。

2、Sweep Payment

The scanner payment model is based on the concept of mobile payment, and the earliest batch of payments made by mobile devices occurred in Finland in 1997. Finnish local media reported that Finland Telecom has launched a service to operate jukeboxes and beverage vending machines by dialing a pay phone number, which can buy Coca-Cola at Helsinki Airport.

The scanned two-dimensional code was invented by Japan DW Company in 1994.

2、扫码支付

扫码支付的模式建立在移动支付的概念上，而最早一批由移动设备完成的付款发生在1997年的芬兰。芬兰当地媒体报道，芬兰电信启用了通过拨打一个付费电话号码来操作点唱机和饮料自动售货机的服务，这项服务可以在赫尔辛基机场买可口可乐。

扫描的二维码则是1994年由日本DW公司发明。

3、Shared bicycle

As early as 1965, Amsterdam Municipal Government of the Netherlands put forward the "White Plan", according to which 50 bicycles were purchased by the government and painted with white paint and scattered around the city for people to use.

This is the earliest unmanned shared bicycle system in the world, so the shared bicycle was invented by the Netherlands. In 2007, France also had the freedom of bicycle travel. Later, it became popular and innovative in China, and promoted overseas.

3、共享单车

早在1965年，荷兰的阿姆斯特丹市政府提出了“白色计划”，根据该计划由政府购置50辆自行车并将其刷上白漆作为记号散放在城市各处供人使用，这是世界上最早的无人管理的共享单车系统，故共享单车由荷兰发明。2007年，法国也有单车自由行，到后来才中国风靡和创新模式发展，并推广海外。

4、online shopping

Online shopping belongs to the category of electronic commerce. In 1979, British Michael Aldrich invented the concept of online shopping. Aldridge used a technology called Videotex to connect ordinary televisions to local retailers'computers over telephone lines.

By the 1990s, after Amazon and eBay launched their websites in 1995, e-commerce began to be popular around the world.

4、网购

网购属于电子商务的范畴。在1979年，英国人麦克·奥德里奇（Michael Aldrich）发明了网上购物的概念。奥德里奇利用一种被称为Videotex的技术，通过电话线将普通电视机连接到了当地零售商的电脑。

到20世纪90年代，亚马逊和eBay在1995年推出了他们的网站后，电子商务开始在全球流行。

❻ 有关中国四大发明的英语短篇作文

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 e 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 instry, 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。 在纸还未发明之前，甲骨、竹简和绢帛是古代用来供书写、记载的材料。但由于西汉的经济、文化迅速发展，甲骨和竹简不能满足发展的需求，从而促使了书写工具的改进。当时人们已开始应用小块的丝绵制成的纸，由于古汉时的纸张是由麻缕和丝绵，加上制法粗糙，所以纸张的质量不太好。而麻缕和丝绵都有其本身的作用，如要把它们用作造纸的原料，就必然会受到很大的限制，而难以得到迅速的发展，来满足文化生活上对纸张的要求。 在新的客观形势要求下，东汉蔡伦的出现为造纸术带来新突破，在《东汉观记》卷二上记载：“蔡伦，有才学，尽忠重慎，每次休沐，闭门以绝宾客，曝体田野。典作尚方，造意用树皮及敝布、鱼网作纸。元兴元年奏上，帝善其能，自是莫不用，天下咸称蔡侯纸”。从以上看来，蔡伦是用树皮、破布、鱼网造纸的。虽然在蔡伦之前也有纸的存在，但是原料本身就有很大的局限，而蔡伦对新原料的发现，解决了这个问题。因为破布、破鱼网早已结束了它们本身的任务，成了废物而又用作做原料，对造纸工业起了极大的推动作用。

❼ 中国四大发明（英语）

The Four Great Inventions of ancient China are, according to Chinese tradition and the British scholar and biochemist Joseph Needham:

The Compass
Gunpowder
Papermaking
Printing
These inventions are celebrated in Chinese culture for their historical significance and as signs of ancient China's advanced science and technology. These four discoveries had an enormous impact on the development of Chinese civilization and a far-ranging global impact.

Although he may have been unaware of the origin of these inventions, in 1620 the English philosopher Francis Bacon noted their importance by writing:
好像对
Printing, gunpowder and the compass: These three have changed the whole face and state of things throughout the world; the first in literature, the second in warfare, the third in navigation; whence have followed innumerable changes, in so much that no empire, no sect, no star seems to have exerted greater power and influence in human affairs than these.

The Four Great Inventions

China's long history has seen some extremely important inventions emerge, most noticeably gunpowder, paper making, printing and the compass, which, in the words of Roger Bacon, changed the whole appearance and status of things in the world.

China was the first country in the world to make proper paper. Paper made ring the Western Han Dynasty (202 BC-16 AD) has been found in Gansu Province, Xi'an and other places in Shaanxi Province as well as Xinjiang. A further development of paper is credited to Cai Lun of the Eastern Han (25-220). He used plant fiber such as tree bark, bits of rope, rags and worn-out fishing nets as raw materials. In 105, Cai presented the first batch of paper made under his supervision to the Han emperor, who was so delighted that he named the material "Marquis Cai's paper". Eastern Han Dynasty paper found in Wuwei, Gansu, in 1974 carried words which were still clearly decipherable. Thin, soft, and with a smooth finish and tight texture, this paper is the most refined and oldest paper discovered to date.

Before paper was invented, the ancient Chinese carved characters on pottery, animal bones and stones, cast them on bronzes, or wrote them on bamboo or wooden strips and silk fabric. These materials, however, were either too heavy or two expensive for widespread use. The invention and use of paper brought about a revolution in writing materials, paving the way for the invention of printing technology in the years to come.

The invention of gunpowder was no doubt one of the most significant achievements of the Middle Ages in China. The correct prescription for making gunpowder with nitre, sulphur and carbon was probably discovered in the ninth century. In fact, in his book, Ge Hong in the third century records the proceres for making a kind of mixture that could be ignited. After the Tang Dynasty (618-907), things took a much faster course as gunpowder was already used in simple hand-grenades which were thrown by a catapult. In 1126, Li Gang, a local official, recorded how he ordered the defenders of the city of Kaifeng to "fire cannons" at the invading Nuzhen tribal people, inflicting heavy casualties on the invaders.

The first prescription for gunpowder appeared in 1044, much earlier than the earliest (1265) gunpowder-making instructions recorded in Europe. By the Song Dynasty (960-1126), gunpowder was in extensive use. Weapons made with it included rifles and rockets. The Song army also used a kind of flame thrower which involved packing gunpowder into bamboo tubes. The earliest picture of a European cannon shows that it bears a striking similarity to Chinese cannon of 1128.

About 1230, the Song army had cannon powerful enough to breach city walls.

A bronze Chinese cannon cast in 1332 is the oldest one in the world extant today. Many bronze and iron cannons have been unearthed in China, most of them bearing inscriptions dating them to between 1280 and 1380.

On the basis of printing using carved blocks in the Tang Dynasty, Bi Sheng of the Northern Song Dynasty invented movable type printing in the 1040s, which ushered in a major revolution in the history of printing.

Bi's printing consisted of four processes: making the types, composing the text, printing and retrieving the movable types. According to Dream Stream Essays, Bi Sheng carved indivial characters on squares of sticky clay, then baked them make clay type pieces. When composing a text, he put a large iron frame on a piece of iron board and arranged the words within the frame. While one plate was being printed, another plate could be composed. After printing, the movable types were taken away and stored for future use. Movable type printing has a very important position in the history of printing, for all later printing methods such as wooden type, copper type and lead type printing invariably developed on the basis of movable clay types. Bi Sheng created movable type printing more than four hundred years earlier than it was invented in Europe.

According to ancient records, natural magnets were employed in China as direction-finding devices. This led to the first compass, called a sinan (south-pointing ladle) ring the Warring States Period. In the Han Dynasty compasses consisted of a bronze on which 24 directions were carved and a rod made from a natural magnet. Such devices were in use until the eighth century.

In the Song Dynasty, Shen Kuo described the floating compass, suspended in water, a technique which minimized the effect of motion on the instrument. This enabled the compass to be used for sea navigation for the first time. The invention of the compass promoted maritime undertakings, and its use soon spread to the Arab world, and thence to Europe.

China's four great ancient inventions made tremendous contributions to the world's economy and the culture of mankind. They were also important symbols of China's role as a great world civilization.

Four Great Inventions of Ancient China -- printing
Block Printing

With the inventions of paper and ink, stamper graally became popular ring 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.

(来源：英语美食指南 http://food.englishcn.com)

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 graally introced 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 indivial 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 rable 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 graally appeared.
The invention of gunpowder had a close relationship with the advanced ancient workmanship of smelting instry. People began to know a lot of chemistry knowledge about the nature of different mineral materials ring 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 proced 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 unknown. (来源：英语麦当劳www.EnglishCN.com)

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 introced.
In the Yuan Dynasty (1279-1368), the method of powder-making was introced 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

(来源：英语问答中心 http://ask.englishcn.com)

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, rable and more suitable for brush writing.

(来源：英语资料下载 http://download.englishcn.com)

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 proced 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.
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 introced to the Arab world and Europe ring 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.
