Let know about The Innovator - Cai Lun (蔡伦) Name｜姓名：Cai Lun (蔡伦), style name Jingzhong (敬仲)。东汉时期著名的宦官、发明家，以改进造纸术名垂青史。 Background｜背景：生于桂阳郡（今湖南）。史料记载其“有才学，精工巧妙”，自幼聪慧机敏，对工艺制造抱有浓厚兴趣，为日后的发明奠定了基础。 Career｜仕途：入宫为宦后官至尚方令，主管皇家作坊。此职位让他得以接触各类原料与能工巧匠，掌握丰富的技术资源，成为改进造纸术的关键契机。 Character｜品格：史载其为人“尽心敦慎，数犯严颜，匡弼得失”，兼具才华、执着与正直的品格。 “伦乃造意，用树肤、麻头及敝布、鱼网以为纸。” ——《后汉书·蔡伦传》 1.7.2013 现在，让我们来认识这位解决了全球难题的人物——蔡伦。他生活在中国东汉时期。蔡伦是一位非常聪明的人，在皇宫中任职。他担任的尚方令这一职位是关键所在：这让他能接触到宫廷作坊丰富的材料、能工巧匠和各种知识，为他日后的实验和创新提供了坚实的基础。蔡伦不仅是一位伟大的发明家，更是一位品德高尚、令人尊敬的人。 ‹#› Lead-in How did paper change the world? Let’s find answers in the text. 02 Pre-reading 1a What material are these things made of ? Find more things that are made of this material? They are all made of paper Read the text and answer the questions. 1b An Invention That Changed the World Can you imagine a world without books, newspapers, or magazines? All of these things depend on one invention—papermaking. It, more than any other invention, was responsible for the rapid spread of information that shaped our modern world. In ancient China, many different materials were used to write on, such as animal bones, bronze ware, stones, wood, bamboo, and even silk. In the Western Han Dynasty, there was also a very early form of paper made from jute—a fibre that comes from plants. However, all of these materials were either difficult to use and store, or very expensive. As the head officer of the palace workshop for the emperor in the Eastern Han Dynasty, Cai Lun became interested in trying to solve the problem. Different methods for creating something to write on were tried, but none were ideal. In his time, some kinds of bark—the outer part of trees—were used to make clothes. From past experiences, Cai Lun got the idea that bark, certain plants, and old clothes could be used to make a special material suitable to write on. In the first step of Cai Lun’s experiment, all the ingredients were mixed and boiled in water. Then, this material was beaten, cut up, and mixed with water again. Next, the liquid was poured over a bamboo screen, leaving just the fibre. Finally, this fibre was dried and pressed to form paper. To everyone’s surprise, this paper was soft, light, easy to make and use, and most importantly, cheap. In 105 CE, Cai Lun showed his creation to the emperor. The emperor was very pleased and praised Cai Lun for his great work. Later on, the papermaking technique not only speeded up the development of Chinese culture, but also changed civilizations around the world. It first spread to China’s neighbouring countries and finally reached Europe through Arabic countries in the 12th century. When the use of paper and printing came together in later centuries, it led to a rapid increase in the number of books. This resulted in a new birth of knowledge, creating the world we have today. 1. What can we predict the topic of this passage is? A. The process and global influence of Cai Lun’s papermaking B. Various writing tools widely used in Western Han Dynasty C. How ancient Chinese people recorded history on silk and bones D. The development of printing in European countries in the 12th century 1 2 3 4 5 Read the text and answer the questions. 1b An Invention That Changed the World Can you imagine a world without books, newspapers, or magazines?

What other ancient Chinese inventions do you know? How was the world changed by them? I know the compass, gunpowder and printing. The compass helped people travel and explore the world. Gunpowder changed wars and later helped with mining and construction. Printing made knowledge spread more easily around the world. 2. What qualities do you think a great inventor has? A great inventor should be creative, hard-working and patient. They need to observe life carefully, try many times, and never give up when they fail. Innovation Process Map： 用六步模型梳理一项发明（以蔡伦造纸为例填写）： 步骤 内容 Problem（问题）   Idea（想法）   Experiment（实验）   Solution（方案）   Invention（发明）   Influence（影响） Summary 1.Words: papermaking, bark, fibre, ingredient, responsible 2. Structure:Intro → Early writing materials → Cai Lun’s idea & process → World influence 3. Paper-making steps: mix & boil → beat & cut → pour on screen → dry & press 4. Chinese inventions: paper, printing, compass, gunpowder Lesson 5 Turn ideas into reality（把创意变成现实） Lesson Question: How do we turn ideas into reality? 创新不是灵光一现，而是“发现需求→提出想法→反复实验→解决问题”的过程。 Innovation is not just a flash of inspiration. It is a process: find a need → form an idea → experiment again and again → solve the problem. Key Points • Follow Cai Lun’s papermaking story and the innovation process map. • Use reading strategies such as prediction, locating details and finding reference words. • Retell an invention through the steps of problem, idea, experiment, solution and influence. Value & Reflection • Real innovation needs patience, action and repeated trying. • Chinese wisdom grows from observing problems and improving life. Keep trying, and an idea can become reality.
