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 --paper-making. 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 wares,
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
第1 / 16
页 共 页interested in trying to solve the problem.Different methods for creating something to write on were
tried, but none were ideal. In his times, some kinds of bark-the outside 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 did not only speed 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.
课文翻译 一项改变世界的发明
你能想象一个没有书籍、报纸或杂志的世界吗？所有这些事物都依赖于一项发明 —— 造纸术。相
较于其他任何发明，正是造纸术推动了信息的快速传播，塑造了我们如今的现代世界。
在中国古代，人们曾使用多种材料书写，比如兽骨、青铜器、石头、木材、竹简，甚至丝绸。西汉
时期，还出现了一种非常原始的麻纸 —— 麻是一种植物纤维。然而，这些材料要么使用和储存不
便，要么价格十分昂贵。
东汉时期，蔡伦担任宫廷作坊的主管官员，他对解决这一问题产生了浓厚兴趣。他尝试了多种制作
书写材料的方法，但都不够理想。在他生活的年代，一些树皮（树木的外层）被用来制作衣物。从过
往的经验中，蔡伦想到：树皮、特定的植物以及旧衣物或许能用来制作一种适合书写的特殊材料。
蔡伦的实验步骤如下：第一步，将所有原料混合并加水煮沸；接着，把这些材料捣碎、切碎，再次
加水搅拌；然后，将混合液倒在竹筛上，只留下纤维；最后，将这些纤维晾干、压实，就制成了纸。
令人惊喜的是，这种纸质地柔软、轻便，制作和使用都很简便，而且最重要的是价格低廉。公元 105
年，蔡伦向皇帝献上了他的发明，皇帝龙颜大悦，对蔡伦的杰出贡献大加赞赏。
后来，造纸术不仅加速了中国文化的发展，也改变了世界各地的文明进程。它首先传播到中国的邻
国，最终在 12 世纪经阿拉伯国家传入欧洲。几个世纪后，当造纸术与印刷术结合起来时，书籍的数
量迅速增多，这催生了知识的新生，造就了我们今天所处的世界。

3a
The invention of the plane has greatly changed the world. However, it seems that its inventors,
Orville Wright and Wilbur Wright, were not looking to change the world at all. Rather, they just
wanted to fly like birds.
To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders.
There were two main challenges. The first was how to get the glider into the air. The second was
how to control it once it was flying. For both problems, they found their solution by looking at
how birds flew. After they solved these problems,they added an engine to the glider. Then, in
December 1903, the world's first plane flights were made.
The invention of the plane has made our travels around the world much easier and faster.
Journeys that once took days, weeks, or even months, can now be made in only a few hours. As
a result, communication among people in different countries is now much easier, and the world has
become a much smaller place.
课文翻译
飞机的发明极大地改变了世界。然而，它的发明者奥维尔・莱特和威尔伯・莱特似乎根本没想过要
改变世界，他们只是想像鸟儿一样飞翔。
为了解决重于空气的飞行难题，莱特兄弟开始研究滑翔机。这面临两大主要挑战：一是如何让滑翔
机升空，二是如何在它飞行时对其进行操控。针对这两个问题，他们通过观察鸟类的飞行方式找到了
答案。解决这些问题后，他们在滑翔机上加装了发动机。随后，在 1903 年 12 月，世界上首次飞
机飞行成功实现。
飞机的发明让我们的环球旅行变得更加便捷、快速。曾经需要数天、数周甚至数月的旅程，如今只
需几个小时就能完成。因此，不同国家的人们之间的沟通变得容易多了，世界也变成了一个小得多的
地方。

二、范文
（一）基础版范文（The Invention of the Plane，80 词）
Can you imagine a world where long-distance travel takes months? The plane is one of the greatest
inventions that changed our lives.
Before 1903, people dreamed of flying like birds, but trains or ships were slow. The Wright brothers
studied gliders, solved the problems of taking off and control, and added an engine. In December 1903, they
made the first successful flight.
The plane makes travel faster and easier. Journeys that took months now take hours. As a result, people
from different countries communicate more easily, and the world becomes smaller. It’s truly a life-changing
invention.
（二）提升版范文（The Invention of Paper，110 词）
Few inventions have shaped human civilization as much as papermaking. It is not an overstatement to say it
connected the world through knowledge.
Before Cai Lun’s invention in 105 CE, ancient people used heavy bamboo, expensive silk, or hard stone to
write. These materials limited the spread of information. Cai Lun changed this by creating paper from cheap
materials like bark and old clothes. His paper was soft, light, and affordable, making it accessible to common
people.
第8 / 16
页 共 页As a result, papermaking speeded up cultural development and spread to Europe via Arabic countries.
Combined with printing, it led to a boom in books and knowledge. Today, paper still plays a key role in
education and daily life, proving that great inventions solve real-world problems.

Asimov. How he loved every story in the book! Reading these wonderful 1 stories, Joseph felt
inspired (受到启发的). He wasn’t just reading about robots, he was going to make them 2 .
Six years later, Joseph met George Devol, an inventor. George had an idea which could make Joseph’s
dream 3 . Joseph learned about it. “This is just like the robots in Asimov’s book,” he said 4
.
In 1958, Joseph and George started working together. Their first 5 , the Unimate, soon came
out. It was a large robotic (机器人的) 6 that could pick up and move objects all by itself. Joseph
wanted the robots to help people do 7 jobs, such as working in hot environments or dealing with
harmful gases (有害气体). The first robotic arms were used in big car factories. This made some work safer and
faster. It was clear that Joseph and George changed the way cars and other things were 8 .

With the development of China, great changes have taken place in our life over these years.
Firstly, people have more and more ways to learn. For example, we used to have classes only at school,
but now thanks to the development of the internet, we can take online courses, which can create a safer
environment to have classes if there is a pandemic (疫情期间).
Secondly, it has become more convenient to travel. We used to ride bikes or walk, but now we can take
different transportation, such as the high-speed train, subway and plane. The development of transportation
provides more chances and ways for us to travel to different places. They can also save our time and money.
Thirdly, the shopping ways also changed a lot. In the past, people needed to go to markets or supermarkets
to buy things. But nowadays, we can buy things or order food online, and the things we buy from any place in
China and even around the world will be quickly sent to our home.
Lastly, the way of communication is also developing. In the past, letters are the only choice, but now
people can chat or video chat on WeChat or QQ, make phone calls or send emails, no matter where they are.
When we miss our family or friends far away, just take out our phones, then they can be in front of us!
It’s happy to see the rapid development of science and technology in China. In the past, many new
technologies were only invented by the western countries, but now China can also do it. With everyone’s hard
work, we Chinese are making it to the top!

box costs about 500 yuan to make, but can increase plant growth by 40%. “I want to help make cities greener,”
Chen said. “Many people live in apartments without gardens, but everyone can grow plants with this box.”
The young inventor spent two years developing his project. He failed over 20 times before succeeding.
His science teacher, Mr. Zhang, said: “Chen doesn’t stop easily when facing problems. He always tries again
and often works in the lab until very late to make his invention better.” Besides, Chen’s parents supported his
research by turning their balcony (阳台) into a testing area.
Over 1,000 students from 50 countries joined the competition. They even won international attention. The
judges praised Chen’s invention, “It can be widely used in daily life and it is environmentally friendly.” Shenzhen
government has promised to support more young inventors like Chen.
Chen plans to improve his invention and hopes to study environmental science at university. “I believe
technology can help solve environmental problems,” he told reporters.
