高二英语Inventions人教版【同步教育信息】一. 本周教学内容Inventions二. 教学重难点重点词组的用法三. 具体内容Four Great Inventions in Ancient ChinaPaperChina was the first nation to invent paper. Before its invention, words were written on various natural materials by ancient peoples-on grass stalks by the Egyptians, on earthen plates by the Mesopotamians, on tree leaves by the Indians, on sheepskin by the Europeans and strangest of all, even inscribed on bamboo or wooden strips, tortoise shells or shoulder blades of an ox by the early Chinese. Later, inspired by the process of silk reeling, the people in ancient China succeeded in first making a kind of paper called “bo” out of silk. But its production was very expensive due to the scarcity of materials. In the early days of the 2nd century, a court official named Cai Lun produced a new kind of paper from bark, rags, wheat stalks and other materials. It was relatively cheap, light, thin, durable and more suitable for brush writing. At the beginning of the 3rd century, the paper making process first spread to Korea and then to Japan. It reached the Arab world in the Tang Dynasty, and Europe in the 12th century. In the16th century, it went to America by way of Europe and then gradually spread all over the world.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.PrintingBefore the invention of printing, dissemination of knowledge depended either on word of mouth or handwritten copies of manuscripts. Both took time and were liable to error. Beginning 2000 years ago in the Western Han Dynasty （206 B.C.—25 A.D.）, stone-tablet rubbing was in vogue for spreading Confucian classics or Buddhist sutras. This led in the Sui Dynasty （581—618）to the practice of engraving writing or pictures on a wooden board, smearing it with ink and then printing on pieces of paper page-by-page. This became known as block printing. The first book with a verifiable date of printing appeared in China in the year 868, or nearly 600 years before that happened in Europe. In the Tang Dynasty （618—907）, this technology was gradually introduced to Korea, Japan, Vietnam, 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 a whole block. In 1041—1048 of the Song Dynasty （960—1279）, a man named Bi Sheng carved individual characters on identical pieces of fine clay which he hardened by a slow baking process, resulting in pieces of movable type. When the printing was finished, the pieces of type were put away for future use. This technology then spread to Korea, Japan, Vietnam and Europe. Later, German Johann Gutenberg invented movable type made of metal in 1440—1448.GunpowderCredit for the invention of gunpowder also goes to ancient China. Ancient necromancersdiscovered in their practice of alchemy, that an explosion could be induced if certain kinds of ores and fuel were mixed in the right proportions and heated, thus leading to the invention of gunpowder. In the Collection of the Most Important Military Techniques, edited in 1044 by Zeng Gongliang, three formulas for making gunpowder were recorded; an explosive mixture of saltpeter, sulfur and charcoal. Dr. Needham identified these as the earliest formulas of such a kind. The method of powder-making was introduced to the Arab world in the 12th century and to Europe in the 14th. Gunpowder was originally used for making fireworks and its later adaptation revolutionized warfare across the world.CompassThe compass, an indispensable navigational tool, was another significant gift from ancient China. While mining ores and melting copper and iron, people chanced upon a natural magnetite that attracted iron and pointed fixedly north. After constant improvement the round compass came into being. Dr. Needham cites one of the first books to describe the magnetic compass, Dream Pool Essays（1086）by Shen Kuo in the Song Dynasty, about 100 years earlier than its first record in Europe by Alexander Neekam in 1190. The compass was introduced to the Arab world and Europe during the Northern Song Dynasty （960—1127）. Before its invention, navigators had to depend on the positions of the sun, the moon and the polestar for their bearings. The spread of the compass to Europe opened the oceans of the world to travel and led to the discovery of the New World. Thus, it was no wonder that Francis Bacon, the English philosopher, pointed out in his work The New Instruments, that the invention of printing, gunpowder and the compass reshaped the world. In his words, they outstripped any empire, any religious belief and any heavenly body in exerting an impact on all humanity.Language Points1. invent vt.（1）发明，创造China’s first automatic four-colour glass printer was invented by a worker-technician.（2）编造；虚构She invented false news.He invented an excuse for his absence.n.[U] 发明（才能）；创造（力）Necessity is the mother of invention.The invention of gunpowder first originated in China.[C] 发明，创造品It’s a most useful invention.There were many inventions in ancient China.Newspapers are full of inventions.2. throwthrow oneself into 积极从事throw away 扔掉throw about 乱丢；乱扔throw up 呕吐throw …at 朝…扔throw…to… 把…传给3. castcast a net 撒网cast a vote 投票cast anchor 抛锚4. havehave sb. do sth. 让某人干某事have sb./ sth. doing sth. 使某人/ 某事在做某事have sth. to do 有要干的某件事have sth. done 让别人做了某事（1）叫别人干某事，强调主语意志，主语使别人干某事I have had the stove lighted.（2）以主语为重点，意味着对主语不利的事，如遭到什么意外。

英语作文invention的重要性和措施
英语作文invention的重要性和措施Inventions: The Key to an Amazing FutureHave you ever wondered how the world became so amazing? How did we go from living in caves to having smartphones, robots, and spaceships? The answer is inventions! Inventions have changed our lives in so many ways, and they will keep making the world better and better if we encourage more inventions to happen.What is an invention? It's a new product, device or process that someone creates for the first time through their creativity and hard work. Inventions solve problems and make our lives easier, more fun, or more amazing in some way. The wheel, the light bulb, the airplane, the computer - these are all incredibly important inventions that transformed how we live.The people who create inventions are called inventors. Inventors are like modern-day wizards who use their intelligence and imagination to bring new ideas to life. They see problems in the world and work hard to find creative solutions. Sometimes inventions happen by accident when someone is experimenting or just playing around with stuff. But most of the time, they arethe result of hard work, persistence, and dedicating your life to trying to improve things.Why are inventions so important? Well, just look around you! Almost everything you use and interact with every day is an invention - your clothes, your toys, your gadgets, the furniture, the windows, even the building you're sitting in. Inventions have made our lives safer, more comfortable, more entertaining, and a whole lot easier than our ancestors who lived in caves and struggled just to find food every day.But inventions don't just make our daily lives better - they also solve huge problems facing the whole world. Medical inventions like vaccines, treatments, and medical devices have saved millions of lives. Inventions in renewable energy, like solar panels and wind turbines, can reduce pollution and help fight climate change. Agricultural inventions help grow more food to feed the world's population. Inventions in technology connect people globally and give us access to more information than ever before. The possibilities of what inventors can create to improve our world are endless!Of course, not every invention works out perfectly right away. The process of inventing usually involves a lot of failures, mistakes, and having to start over before succeeding. ThomasEdison tried thousands of different materials before finally inventing the first long-lasting light bulb. The Wright brothers crashed many early plane models before getting one to finally fly. Inventions often go through many generations of improvements and updates too. The first computers were huge, clunky machines, but each new model got better, smaller, and more powerful as inventors improved the original idea.So if inventions are so important for creating the amazing modern world we live in, how can we make sure more inventions keeping happening in the future? Here are some key things we need to encourage inventions:Nurture curiosity and creativity from a young age. The inventors of tomorrow are the kids of today playing with toys, taking things apart, asking questions, and dreaming up new ideas through their imagination. Parents, teachers, and society need to encourage curious thinking and give kids the freedom to explore, experiment, and be creative without too many limits.Invest in education, especially in science, technology, engineering, and math (STEM). The more kids learn about how the world works at a deep level, the better equipped they'll be as adults to understand problems and come up with inventivesolutions. Having a strong base of STEM knowledge and skills is key for future inventors.Provide resources and opportunities for inventors of all ages. Things like makerspaces with tools and materials for inventors to work on projects, competitions and programs that fund new ideas, and laws that protect inventions with patents all help give inventors what they need to bring their ideas to life.Appreciate failures and reward efforts, not just results. Failure is a huge part of the invention process, but it shouldn't be punished or seen as a bad thing. We need to change attitudes to understand that failing is just a step towards succeeding, and keep supporting inventors who persist through multiple failures to finally succeed.Expose people to role models of diverse, successful inventors. Seeing people like themselves as inventors can inspire more underrepresented groups like women, minorities, and people with disabilities to get involved and feel like they can be inventors too. The more diverse the pool of potential inventors is, the more amazing new ideas we'll get.Encourage collaboration and sharing of ideas. Inventions often build off other inventions when people combine different ideas in new ways. Bringing people together to collaborate onprojects and freely share knowledge can lead to even greater inventions than what anyone could do alone.The rate of new inventions has been speeding up throughout history. The more inventions we have, the more tools and knowledge we gain to drive even more inventions going forward. As long as we keep nurturing invention through curiosity, education, resources and perseverance, there's no limit to what the inventors of the future may create. New inventions could help us travel to other planets, find cures for diseases, produce unlimited clean energy, or bring about amazing things we can't even imagine yet!The future is yours to invent, so let your creativity and curiosity soar to create inventions that will make the world an even more wondrous place. You could change the world with your ideas, so keep inventing!。
