The Four Great Inventions 四大发明

The Compass 指南针

Diagram of a Ming dynasty mariner's compass
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

Hemp wrapping paper, China, circa 100 BC
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.

The intricate frontispiece of the Diamond Sutra from Tang Dynasty China, AD 868 (British Museum)
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.别要我逐句翻译，我办不了

⑷ 发明家英语介绍

英语属于印欧语系中日耳曼语族下的西日耳曼语支，由古代从欧洲大陆移民大不列颠岛的盎格鲁、撒克逊和朱特部落的日耳曼人所说的语言演变而来，并通过英国的殖民活动传播到世界各地。
早期日耳曼人部落（弗里西族、盎格鲁族、撒克逊族与朱特族）移民到英格兰，英语就是从他们的语言中变化继承下来。据《盎格鲁撒克逊编年史》记载，公元449年左右，不列颠群岛国王伏提庚（Vortigern）邀请“盎格鲁亲戚们”来帮助他对抗皮克特人。作为回报，他赐予盎格鲁族东南部的领土。随后他又进一步寻求支援，撒克逊族、盎格鲁族与朱特族人纷纷前来。《编年史》记载，最终这些“移民”建立了七个王国：诺森伯利亚、麦西亚、东盎格利亚、肯特、埃塞克斯、苏塞克斯、威塞克斯。
日尔曼人入侵后，统治了当地的凯尔特语民族，本地语言主要於苏格兰、威尔士、康沃尔与爱尔兰存活了下来。这些入侵者的语言逐渐形成了“古英语”，与近代弗里西语极为相象。English（英格兰人、英语）、England（英格兰）和East Anglia（东盎格利亚）这三个词是分别从描绘盎格鲁族的词汇发展而来：Englisc、 Angelcynn、Englaland。
1066年诺曼征服后三百年内，英格兰的国王只讲法语。因此一大批法语词汇进入了古英语，古英语本身也失去了大部分曲折变化，进化为中古英语。1500年左右的元音大推移将中古英语变形为近代英语。古英语最著名的文学作品是《贝奥武夫》，中古英语则是《坎特伯雷故事集》。
近代英语在莎士比亚所处的时期开始繁荣，一些学者将之分为早期近代英语与后期近代英语，分界线为1800年左右。随着不列颠对全世界大部分地区的占领和殖民，当地语言也很大程度上影响了英语的发展。

美国大选结果将短暂影响全球市场美国大选结果不单只左右美国的走向，也会影响美股和全球股市在未来四年的走势。按历史传统，美国华尔街较不喜欢民主党。但是，这次美国大选却遇上百年一遇的全球金融海啸，美国经济基本上已经进入衰退，当地人心急切求变。不过，现在更为复杂的是衰退只是刚刚开始，萧条阴影正笼罩市场。奥巴马的当选能否成为改善美国经济的兴奋剂，或替经济带来转机，环球市场正密切关注。奥巴马支持实施金融救援计划，不过笔者观察其言论，他认为救市只是临时措施，应同时加强市场监管，在救市过程中也应推动实施为中产阶级减税和刺激经济增长的计划。奥巴马获胜，笔者估计他会更多考虑穷人的利益，另外可能也会改变对外出口方面的政策。从政策面看，美国在税收、能源、社会保障、医疗保健、住房以及对外贸易等方面或将出现改变，奥巴马入主白宫的未来四年，将对美国经济产生深远影响，因此我们必须留意新总统上任后的实际行动。在美国大选前，内地A股市场再度出现了调整，市场萎缩反映了资金尚未恢复投资热情，即使连续推出利好政策，也未能激起市场的参与热情。但是在美国大选尘埃落定后，市场在短期未必对市场看得太淡。在这前提下，环球气氛有望打破内地市场闷局，但是这并不代表经济基本面转好。美国大选不会改变经济衰退的趋势，即使短期美股出现进一步的反弹，笔者也只能将之定性为反弹，不排除在明年年中前再次寻底的可能性。经过上月市场暴跌后，A股市场在短期内暴挫的机会较小，不过投资者应该保持谨慎。在目前经济衰退的情况下，企业盈利前景黯淡，因此市场仍存在不少价值被高估的企业，若没有业绩支撑，股价将进一步的回归到更为理性的水平。虽然美股短期出现了反弹迹象，但这并不代表A股将同样迎接反弹。短期气氛可能改善，当前A股市场仍然处于企业业绩不明朗期，持有现金或将仍是内地基金界明年初最佳的投资策略。山寨文化折射中国尴尬境地!从山寨手机开始，一股汹涌的山寨文化浪潮席卷了整个中国大地，就连周围第三世界小国甚至是欧美等强国也不同程度的被山寨所影响。“山寨”一词,原本指没牌照、难进正规渠道的小厂家、小作坊,引申为盗版、剽窃、仿制的同义词。现在，各行各业以山寨手机为榜样，自发的发起了学山寨运动，消费者对于购买山寨产品乐此不疲，学者、专家们铺天盖地的撰写文章大肆的评论山寨，就连新闻联播也开始报道山寨现象。其实，山寨的产业链正在形成，而寨文化对中国的影响才刚刚开始。说起山寨的流行，不得不从山寨手机说起。山寨手机规避了行业监管、研发、知识产权、售后服务的限制，套上明星脸的外形以超低廉的价格推向市场，迅速吸引众多粉丝，牢牢占有一部分市场份额，割据一方。价格优势是山寨手机的杀手锏，同时也是对垄断利益集团反抗的最强音。很早以前，为了对企业或个人的脑力成果进行保护，西方国家颁布了一系列的政策来保护知识产权，目的是保护开发者的利益，鼓励企业与个人进行创新。时至今日，大财团依靠不断的发展与市场竞争，积累了空前的资本与技术优势，几个大公司由于掌握核心技术，可以在一个产业领域内呼风唤雨，甚至能够左右这个产业内产品的价格。由于技术壁垒的限制，中小企业无法与垄断企业竞争，就算是自己能够独立生产的商品也要向掌握核心技术的企业交纳专利技术使用费，或者直接购买核心零部件。这就好像某人发现咖啡里加上牛奶也很好喝，于是便申请专利，别人不可以这么做，想喝加牛奶的咖啡只能去他那里买。这种“技术”在享受到一段时间的保护、得到了很多利益的时候就应该可以开放了，可是当人们都自发的掌握这种“技术”以后，政府仍旧还在保护，既然你们自己也会做了，那就交专利费好了，交了钱就允许你们自己做。直到很久以后，就连退休的老奶奶也会做了，根本就没人再去交专利费了，这种“专利技术”终于没有保护的价值了，政府就把它彻底开放了。原来那个人早就赚得数钱数到手发软，然后发明了更好的方法再去申请专利，或者拥有了巨无霸式的连锁品牌“黑白分明”。垄断企业利用原有的优势与知识产权政策，不断稳固自己的垄断地位，然后再对中小企业进行剥削。保护知识产权政策初衷是保护自主创新的利益与鼓励技术竞争，可是到如今却成了既得利益集团稳固自己地位、打压弱小竞争者的工具。这些弱小的企业在面对大财团时就正好折射出了中国在面对欧美强国时的尴尬处境。从新中国成立的那天开始，中国的领导人一直致力于把中国建设成为世界上的工业强国。时过境迁，中国已经真的变成世界工厂，可是中国人却发现，发达国家在中国设厂，大肆挥霍着中国的电力、煤炭、石油等基础生产资源，生产的原材料也在中国就地取材，还要享受各种优惠政策与减税待遇，解决的就业问题也是以对中国工人阶级进行更残酷的剥削为代价换来的，中国只能得到利润的一小部分。在技术领域内，中国不但没有任何优势，而且根本就没有发言权，只能是受欺压的角色。西方国家的财团原本就是勾结本国政府利用技术打压中小企业，保护自己的既得利益，实现了政府与财团的双赢。现在他们又有了一个新的理由来维持现在这个局面，那就是利用技术资本对以中国为首的第三世界国家进行剥削。打着保护知识的幌子，实则进行垄断经营，压制新兴国家与企业的发展，使他们永远趴在产业链的下游。中国确实很无奈，这是后来者的烦恼，也是任何后来者所必须面对的，已经形成的格局是那么牢固，中国想挤到上去分一杯羹是那么困难，因为原有秩序的建立者利用“知识产权”这把利器把中国牢牢压在身下，被剥夺了脑力劳动权利的中国只能乖乖的进行体力劳动。其实，我们所用的盗版软件就是模仿最好的山寨产品了，中国政府的态度一直就是很暧昧，一方面也希望建立良好的知识产权秩序，另一方面对欧美的技术垄断深恶痛绝，希望借助山寨的力量以最小的成本发展中国的信息化建设，对欧美国家的技术成果以巧取的方式武装自己。微软的黑屏事件其实是微软公司与中国政府互相的无奈。可是，在全球化进程加快的今天，这种不那么正大光明的做法越来越没有空间了，特别是中国想要成为强国，仅仅停留在山寨层次是不行的。就算是在国内占山为王，天皇老子管不了，但终究不能进入国际市场进行竞争，中华民族是有远大抱负的，不可能满足于山寨档次的。山寨产品想要继续发展，最根本的就是赚取利润，然后进行研发，摇身变成真正的科技产品。山寨产品是否能够完成不那么光彩的原始积累，以反垄断英雄的形象屹立起来，我们只能拭目以待了。

冰箱的由来( The origin of refrigerator)
By the mid-nineteenth century, the term"icebox"had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.

Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, more explained, was that farmers would no longer have to travel to market at night in order to keep their proce cool.

直到19世纪中期，"冰箱"这个名词才进入了美国语言，但冰仅仅只是开始影响美国普通市民的饮食。 冰的买卖随着城市的发展而发展。 冰被用在旅馆、酒馆、医院以及被一些有眼光的城市商人用于肉、鱼和黄油的保鲜。 内战(1861-1865)之后，冰被用于冷藏货车，同时也进入了民用。 甚至在1880年前，半数在纽约、费城和巴尔的摩销售的冰，三分之一在波士顿和芝加哥销售的冰进入家庭使用，因为一种新的家庭设备，冰箱，即现代冰箱的前身，被发明了。 制造一台有效率的冰箱不像我们想象的那么简单。 19世纪早期，关于对冷藏科学至关重要的热物理知识是很浅陋的。 认为最好的冰箱应该防止冰的融化这样一个普遍的观点显然是错误的，因为正是冰的融化起了制冷作用。 早期为节省冰的努力，包括用毯子把冰包起来，使得冰不能发挥它的作用。 直到近19世纪末，发明家们才成功地找到有效率的冰箱所需要的精确的隔热和循环的精确平衡。 但早在1803年，一位有发明天才的马里兰农场主，托马斯·莫尔，找到了正确方法。 他拥有一个农场，离华盛顿约20英里，那里的乔治镇村庄是集市中心。 当他用自己设计的冰箱运送黄油去市场时，他发现顾客们会走过装在竞争者桶里那些迅速融化的黄油而给他比市价更高的价格买他仍然新鲜坚硬，整齐地切成一磅一块的黄油。 莫尔说他的冰箱的一个好处是使得农民们不必在夜里上路去市场以保持他们产品的低温。

⑼ 用英语介绍一位发明家

贝尔

Alexander Graham Bell was born in Scotland. His mother, who was deaf, was a musician and a painter of portraits. His father, who taught deaf people how to speak, invented "Visible Speech". This was a code which showed how the tongue, lips, and throat were positioned to make speech sounds. Graham, or "Aleck", as his family called him, was interested in working with the deaf throughout his life.

Thomas Watson became an associate of Bell. He made parts and built models of Bell's inventions. One day while they were working Bell accidently heard the sound of a plucked reed * coming over the telegraph wire. Watson had been tuning the metal reeds in the next room. Bell drew up a plan for the telephone and they continued to experiment. The next day he transmitted the famous words, "Mr. Watson, come here. I want you!" A few months later on Feb. 14, 1876, he applied for a patent on his telephone.

He continued to invent other things. He developed a method of making phonograph * records on a wax disc. He made an iron breathing lung, and a device for locating icebergs at sea. He experimented with sheep. He was interested in kites that could lift a man, and he invented a hydrofoil * which set a world speed record of over 70 miles per hour.
