An Invention That Changed the World 一项改变世界的发明
Can you imagine a world without books, newspapers, or magazines? 你能想象一个没有书籍、报纸或杂志的世界吗？
All of these things depend on one invention—papermaking. 所有这一切都依赖于一项发明——造纸术。
It, more than any other invention, was responsible for the rapid spread of information that shaped our modern world. 相较于其他任何发明，正是它推动了信息的快速传播，而这种传播塑造了我们的现代世界。
In ancient China, many different materials were used to write on, such as animal bones, bronze ware, stones, wood, bamboo, and even silk. 在古代中国，人们使用许多不同的材料来书写，比如兽骨、青铜器、石块、木板、竹简，甚至丝绸。
In the Western Han Dynasty, there was also a very early form of paper made from jute—a fibre that comes from plants. 西汉时期已经出现了一种早期形态的纸，它由黄麻（一种植物纤维）制成。
However, all of these materials were either difficult to use and store, or very expensive. 然而，这些材料要么难以使用和保存，要么价格非常昂贵。
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. 作为东汉时期皇宫御用作坊的主管官员，蔡伦对解决这一难题产生了兴趣。
Different methods for creating something to write on were tried, but none were ideal. 人们尝试了多种制作书写材料的方法，但效果都不理想。
In his time, some kinds of bark—the outer part of trees—were used to make clothes. 在他那个时代，某些树皮（树木的外层）被用来制作衣物。
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. 结合过往经验，蔡伦有了一个主意：树皮、某些植物和旧衣物可以用来制作一种适合书写的特殊材料。
In the first step of Cai Lun's experiment, all the ingredients were mixed and boiled in water. 蔡伦实验的第一步，是把所有原料混合在一起，放入水中煮沸。
Then, this material was beaten, cut up, and mixed with water again. 然后，这些材料被捣烂、切碎，再次与水混合。
Next, the liquid was poured over a bamboo screen, leaving just the fibre. 接下来，将这种浆液倒在竹帘上，只留下纤维。
Finally, this fibre was dried and pressed to form paper. 最后，这种纤维被晾干、压平，然后制成纸张。
To everyone's surprise, this paper was soft, light, easy to make and use, and most importantly, cheap. 令所有人意外的是，这种纸柔软轻便，易于制作和使用，最重要的是成本低廉。
In 105 CE, Cai Lun showed his creation to the emperor. 公元105年，蔡伦把他的发明呈献给皇帝。
The emperor was very pleased and praised Cai Lun for his great work. 皇帝十分满意，对蔡伦的杰出成果大加赞赏。
Later on, the papermaking technique not only speeded up the development of Chinese culture, but also changed civilizations around the world. 后来，造纸术不仅促进了中国文化的发展，也改变了世界各地的文明。
It first spread to China's neighbouring countries and finally reached Europe through Arab countries in the 12th century. 它首先传入中国的邻国，并最终在12世纪经由阿拉伯国家传入欧洲。
When the use of paper and printing came together in later centuries, it led to a rapid increase in the number of books. 此后几个世纪里，纸张与印刷术相结合，书籍的数量因此急剧增长。
This resulted in a new birth of knowledge, creating the world we have today. 这催生了一场知识的新生，造就了我们今天所处的世界。
3a. Read the text and complete the chart. 3a. 阅读课文并完成图表。
The invention of the plane has greatly changed the world. 飞机的发明极大地改变了世界。
However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. 然而，它的发明者——奥维尔·莱特和威尔伯·莱特，似乎根本无意改变世界。
Rather, they just wanted to fly like birds. 更准确地说，他们只是想像鸟儿一样飞翔。
To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. 为攻克重于空气的飞行器的飞行难题，莱特兄弟开始研究滑翔机。
There were two main challenges. 他们主要面临两大挑战：
The first was how to get the glider into the air. 一是如何让滑翔机升空，
The second was how to control it once it was flying. 二是如何在飞行中对其进行操控。
For both problems, they found their solutions by looking at how birds flew. 针对这两个问题，他们通过观察鸟类的飞行方式找到了解决方法。
After they solved these problems, they added an engine to the glider. 解决这些难题后，他们为滑翔机加装了发动机。
Then, in December 1903, the world's first plane flights were made. 1903年12月，世界上首次飞机飞行取得成功。
The invention of the plane has made our travels around the world much easier and faster. 飞机的发明使环球旅行变得更加便捷。
Journeys that once took days, weeks, or even months, can now be made in only a few hours. 过去耗时数日、数周甚至数月的旅程，如今仅需短短数小时。
As a result, communication among people in different countries is now much easier, and the world has become a much smaller place. 因此，各国人民之间的交流变得更加便利，世界也变得小了许多。
