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 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. Cai Lun was the head officer of the palace workshop for the emperor in the Eastern Han Dynasty. 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. 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. 26．What do books, newspapers and magazines all depend on? A．The radio. B．Papermaking. C．The printing machine. D．The 3D printer. 27．What was used to write on before Cai Lun's paper? A．Only silk. B．Only bamboo and wood. C．Animal bones, bronze wares, stones, wood, bamboo and silk. D．Only jute. 28．Where did Cai Lun get his idea for making paper? A．From old books about chemistry. B．From the emperor's advice. C．From his travels to Europe. D．From past experiences of using bark to make clothes. 29．The underlined word "poured" in Paragraph 4 means ________. A．倒、浇 B．煮沸 C．采摘 D．搅拌 30．What is the main idea of the last paragraph? A．How paper was made step by step. B．Why Cai Lun became a head officer. C．How papermaking changed the world. D．How expensive silk was in ancient China. The Most Useful Invention of All Time Fu Xing: What do you think is the most useful invention of all time, Peter? Peter: It has to be the radio. Fu Xing: The radio? Why? Peter: Before the radio was invented, information travelled very slowly. The world was made much smaller by the radio. Suddenly, news could be spread around the world in seconds. Fu Xing: Right. Who was the inventor? Peter: An Italian inventor called Guglielmo Marconi. He developed the idea in the 1890s. In 1901, a radio message was sent across the Atlantic Ocean for the first time. Fu Xing: Wow! That was quite a distance at that time. Peter: Yeah. And because of the radio, some other important inventions were developed as well. Fu Xing: Like the television? Peter: That's right. It also had a big effect on music. The radio made it much easier for people to enjoy music from artists around the world. 31．What does Peter think is the most useful invention of all time? A．The television. B．The radio. C．The telephone. D．The plane. 32．What was the world like before the radio was invented? A．Information travelled very slowly. B．News was spread in seconds. C．People enjoyed music everywhere. D．The telephone was already popular. 33．Who developed the idea of the radio? A．Fu Xing. B．A Chinese inventor. C．Guglielmo Marconi. D．Nobody knows. 34．What happened in 1901? A．Television was invented. B．A radio message was sent across the Atlantic Ocean. C．Marconi won a prize. D．The first plane was made. 35．What can we learn from the conversation? A．The radio only helped people listen to music. B．One invention often leads to other important inventions. C．Television was invented before the radio. D．Marconi was a musician as well as an inventor. The Wright Brothers and the First Plane 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. 36．Why did the Wright brothers want to invent the plane? A．To become rich and famous. B．They just wanted to fly like birds. C．To win a competition. D．To carry heavy things. 37．What were the two main challenges? A．Finding an engine and buying gliders. B．Saving money and finding teachers. C．Getting the glider into the air and controlling it. D．Making seats and windows. 38．How did they find the solutions? A．By reading science fiction. B．By asking their father for help. C．By watching how birds flew. D．By studying the radio. 39．When were the world's first plane flights made? A．In 1901. B．In December 1903. C．In the 1890s. D．In 105 CE. 40．What is the last paragraph mainly about? A．The effect of the invention of the plane. B．The life of the Wright brothers. C．How gliders were made. D．Why people liked travelling. 四、任务型阅读 There is an invention exhibition in our city this weekend. A guide is introducing two inventions to the visitors. Guide: Welcome to the exhibition, everyone!

A mini-camera is connected to the front of the glasses. It helps people with poor eyesight read books more easily. Visitor B: Amazing! What about that machine over there? Guide: It is called Smart Cook. Hundreds of kinds of dishes can be made by it. The oil and salt are also added by the machine itself, so you don't need to do anything. Visitor A: Really? Is it easy to operate? Guide: Quite easy. But first, a button on Smart Cook should be pressed before cooking. Then you can wait and enjoy your meal.
