A. 四大发明的发明者
指南针的发明者历史上并没有说明。中国是世界上公认发明指南针（Compass）的国家。指南针的发明是我国汉族劳动人民在长期的实践中对物体磁性认识的结果。由于生产劳动，人们接触了磁铁矿，开始了对磁性质的了解。人们首先发现了磁石吸引铁的性质，后来又发现了磁石的指向性。经过多方面的实验和研究，终于发明了实用的指南针。最早的指南针是用天然磁体做成的，这说明中国汉族劳动人民很早就发现了天然磁铁及其吸铁性。据古书记载，远在春秋战国时期，由于正处在奴隶制社会向封建社会过渡的大变革时期，生产力有了很大的发展，特别是农业生产更是兴盛发达，因而促使了采矿业、冶炼业的发展。在长期的生产实践中，人们从铁矿石中认识了磁石。最早的指南针是司南。
造纸术（也称蔡侯纸）蔡伦改进。东汉和帝元兴元年(公元105年)，蔡伦在总结前人制造丝织晶的经验的基础上，用树皮、破渔网、破布、麻头等作为原料，制造成了适合书写的植物纤维纸，改进了造纸术，才使纸成为人们普遍使用的书写材料。被称为“蔡侯纸”。
火药是中国汉族炼丹家发明于隋唐时期，距今已有一千多年了。火药的研究开始于古代道家炼丹术，古人为求长生不老而炼制丹药，炼丹术的目的和动机都是超前的，但它的实验方法还是有可取之处，最后导致了火药的发明。
印刷术据载是北宋时期毕升发明了胶泥活字印刷术，被认为是世界上最早的活字印刷技术。但四大发明中的活字印刷术并非现代印刷术的前身，而据李约瑟所论北宋制的胶泥活字印刷术有许多劣势的地方。
B. compass这个发明的重要性

C. 求英语大神翻译：中国是举世公认的发明指南针（compass)的国家。最初的指南针叫做司南 ( Si
中国是举世公认的发明compass的国家。最初的指南针叫做 Sinan, a south-pointing ladle,出现在战国时期。一般在指南针上标有东南西北四个方位，并且还有刻度。北对应零度，刻度随顺时针方向而增加。作为中国古代的四大发明之一，指南针对人们的生活，尤其是航海业的发展，起到了重要的作用。指南针对西方世界也产生了显著的影响，这些国家由此开始了大规模的海外冒险活动。
China is widely recognized as a country with the invention of compass. The initial compass is called a, south-pointing ladle Sinan, which appeared in the Warring States period. There are four directions of the compass in the southeast and northwest superscript, and scale. The corresponding zero scale with clockwise increases. As one of the four great inventions of ancient China, compass on people's life, especially the development of shipping instry has played an important role. The compass also has significant impact on the western world, these countries began a large-scale overseas adventure.

The Four Great Inventions 四大发明
The Compass 指南针

Main article: Compass
The earliest reference to magnetism in Chinese literature is found in a 4th century BC book called Book of the Devil Valley Master (鬼谷子): "The lodestone makes iron come or it attracts it."
The earliest reference to a magnetic device used as a "direction finder" is in a Song Dynasty book dated to AD 1040-44. Here there is a description of an iron "south-pointing fish" floating in a bowl of water, aligning itself to the south. The device is recommended as a means of orientation "in the obscurity of the night." However, the first suspended magnetic needle compass was written of by Shen Kuo in his book of AD 1088.
For most of Chinese history, the compass that remained in use was in the form of a magnetic needle floating in a bowl of water. According to Needham, the Chinese in the Song Dynasty and continuing Yuan Dynasty did make use of a dry compass, although this type never became as widely used in China as the wet compass.
The dry compass used in China was a dry suspension compass, a wooden frame crafted in the shape of a turtle hung upside down by a board, with the loadstone sealed in by wax, and if rotated, the needle at the tail would always point in the northern cardinal direction. Although the 14th century European compass-card in box frame and dry pivot needle was adopted in China after its use was taken by Japanese pirates in the 16th century (who had in turn learned of it from Europeans), the Chinese design of the suspended dry compass persisted in use well into the 18th century.
Gunpowder 火药
Handgun from the Yuan dynasty, circa 1300s.
Main article: History of gunpowder
The prevailing academic consensus is that gunpowder was discovered in the 9th century by Chinese alchemists searching for an elixir of immortality. By the time the Song Dynasty treatise, Wujing Zongyao (武经总要), was written by Zeng Gongliang and Yang Weide in AD 1044, the various Chinese formulas for gunpowder held levels of nitrate in the range of 27% to 50%. By the end of the 12th century, Chinese formulas of gunpowder had a level of nitrate capable of bursting through cast iron metal containers, in the form of the earliest hollow, gunpowder-filled grenade bombs.
In AD 1280, the bomb store of the large gunpowder arsenal at Weiyang accidentally caught fire, which proced such a massive explosion that a team of Chinese inspectors at the site a week later deced that some 100 guards had been killed instantly, with wooden beams and pillars blown sky high and landing at a distance of over 10 li (~2 mi. or ~3.2 km) away from the explosion.
By the time of Jiao Yu and his Huolongjing in the mid 14th century, the explosive potential of gunpowder was perfected, as the level of nitrate in gunpowder formulas had risen to a range of 12% to 91%, with at least 6 different formulas in use that are considered to have maximum explosive potential for gunpowder. By that time, the Chinese had discovered how to create explosive cannonballs by packing their hollow shells with this nitrate-enhanced gunpowder.
Papermaking 造纸术

Main article: Papermaking
Further information: Science and technology of the Han Dynasty
Papermaking has traditionally been traced to China about AD 105, when Cai Lun, an official attached to the Imperial court ring the Han Dynasty (202 BC-AD 220), created a sheet of paper using mulberry and other bast fibres along with fishnets, old rags, and hemp waste. However a recent archaeological discovery has been reported from near Dunhuang of paper with writing on it dating to 8 BC.
While paper used for wrapping and padding was used in China since the 2nd century BC, paper used as a writing medium only became widespread by the 3rd century. By the 6th century in China, sheets of paper were beginning to be used for toilet paper as well. During the Tang Dynasty (AD 618–907) paper was folded and sewn into square bags to preserve the flavor of tea. The Song Dynasty (AD 960–1279) that followed was the first government to issue paper currency.
Printing 印刷术
Main article: History of typography in East Asia
The Chinese invention of Woodblock printing, at some point before the first dated book in 868 (the Diamond Sutra), proced the world's first print culture. According to A. Hyatt Mayor, curator at the Metropolitan Museum of Art, "it was the Chinese who really discovered the means of communication that was to dominate until our age." Woodblock printing was better suited to Chinese characters than movable type, which the Chinese also invented, but which did not replace woodblock printing. Western printing presses, although introced in the 16th century, were not widely used in China until the 19th century. China, along with Korea, was one of the last countries to adopt them.

Woodblock printing for textiles, on the other hand, preceded text printing by centuries in all cultures, and is first found in China at around 220, then Egypt in the 4th century, and reached Europe by the 14th century or before, via the Islamic world, and by around 1400 was being used on paper for old master prints and playing cards. In another analysis Hyatt Mayor states that "a little before 1400 Europeans had enough paper to begin making holy images and playing cards in woodcut. They need not have learned woodcut from the Chinese, because they had been using woodblocks for about 1,000 years to stamp designs on linen."
Printing in China was further advanced by the 11th century, as it was written by the Song Dynasty scientist and statesman Shen Kuo (1031-1095) that the common artisan Bi Sheng (990-1051) invented ceramic movable type printing.Then there were those such as Wang Zhen (fl. 1290-1333) and Hua Sui (1439-1513), the former of whom invented wooden movable type printing in China, the latter of whom invented metal movable type printing in China. Movable type printing was a tedious process if one were to assemble thousands of indivial characters for the printing of simply one or a few books, but if used for printing thousands of books, the process was efficient and rapid enough to be successful and highly employed. Indeed, there were many cities in China where movable type printing, in wooden and metal form, was adopted by the enterprises of wealthy local families or large private instries. The Qing Dynasty court sponsored enormous printing projects using woodblock movable type printing ring the 18th century. Although superseded by western printing techniques, woodblock movable type printing remains in use in isolated communities in China.
