It connects Xining to Lhasa, a huge distance of 1,956 kilometres. 39. It is the highest railway in the world, reaching 5,072 metres above sea level at Tanggula Pass. 40. The building of the railway was a great challenge. 41. Creative ideas were needed to solve different problems. 42. In summer, the top layer of the frozen ground would melt and become too soft to build on. 43. Pipes were used to keep the ground hard. 44. However, in some places, it was impossible to build the railway over the frozen ground. 45. So tunnels had to be created instead. 46. Bridges were built to keep the railway up above the ground. 47. These bridges are animal-friendly and allow animals to pass under the tracks. 48. As an important and successful project, the railway has increased tourism and economic development in the area. 49. The lessons learnt and experience gained from building this railway will help improve transport in other similar places in the world. 50. How do we turn ideas into reality? 51. Can you imagine a world without books, newspapers, or magazines? 52. All of these things depend on one invention—papermaking. 53. It, more than any other invention, was responsible for the rapid spread of information that shaped our modern world. 54. In ancient China, many different materials were used to write on, such as animal bones, bronze wares, stones, wood, bamboo, and even silk. 55. In the Western Han Dynasty, there was also a very early form of paper made from jute—a fibre that comes from plants. 56. However, all of these materials were either difficult to use and store or very expensive. 57. 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. 58. Different methods for creating something to write on were tried, but none were ideal. 59. In his times, some kinds of bark—the outside part of trees—were used to make clothes. 60. 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. 61. In the first step of Cai Lun's experiment, all the ingredients were mixed and boiled in water. 62. Then, this material was beaten, cut up, and mixed with water again. 63. Next, the liquid was poured over a bamboo screen, leaving just the fibre. 64. Finally, this fibre was dried and pressed to form paper. 65. To everyone's surprise, this paper was soft, light, easy to make and use, and, most importantly, cheap. 66. In 105 CE, Cai Lun showed his creation to the emperor. 67. The emperor was very pleased and praised Cai Lun for his great work. 68. Later on, the papermaking technique did not only speed up the development of Chinese culture, but also changed civilizations around the world. 69. It first spread to China's neighbouring countries and finally reached Europe through Arabic countries in the 12th century. 70. When the use of paper and printing came together in later centuries, it led to a rapid increase in the number of books. 71. This resulted in a new birth of knowledge, creating the world we have today. 72. The invention of the plane has greatly changed the world. 73. However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. 74. Rather, they just wanted to fly like birds. 75. To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. 76. There were two main challenges. 77. The first was how to get the glider into the air. 78. The second was how to control it once it was flying. 79. For both problems, they found their solution by looking at how birds flew. 80. After they solved these problems, they added an engine to the glider. 81. Then, in December 1903, the world's first plane flights were made. 82. The invention of the plane has made our travels around the world much easier and faster. 83. Journeys that once took days, weeks, or even months, can now be made in only a few hours. 84. As a result, communication among people in different countries is now much easier, and the world has become a much smaller place. 85. Did you know that an accident led to the invention of sticky notes? 86. In 1968, a scientist named Spencer Silver was trying to make a strong glue. 87. To his surprise, he produced a glue that was really weak. 88. It could stick things, but it could be removed very easily. 89. The glue was interesting, but no one could find a use for it. 90. Then, in 1974, a man named Arthur Fry was trying to mark the pages in a song book using small pieces of paper. 91. However, whenever he stood up to sing, the pieces fell to the floor. 92. Then he remembered Silver's glue. 93. With the glue, the paper stayed in the song book, but it could later be removed. 94. Fry's idea resulted in the production of sticky notes of many sizes and colours. 95. They gradually became popular and now are widely used all over the world. 96. Do you have any ideas about what will make the world a better place? 97. We are looking for inventions in the following areas. 98. Your invention should meet the following requirements. 99. If you have an invention like this, apply today! 100.

The telephone was invented by Alexander Bell in 1876. Toys, chairs, tables, and even houses can all be made by the 3D printer. 2. 被动语态的构成 一般现在时被动语态：am / is / are + done 一般过去时被动语态：was / were + done 情态动词被动语态：can / may / must / should + be + done 现在完成时被动语态：have / has + been + done 一般将来时被动语态：will + be + done 含 have to / be supposed to / be believed to 的被动语态：have to be done / be supposed to be done / be believed to be done 例：People all over the world are connected to each other through the Internet. 例：A radio message was sent across the Atlantic Ocean in 1901. 例：The word "robot" was introduced for the first time in a play in 1920. 例：It is believed that the world's oldest wheel was found in Eastern Europe. 例：Tunnels had to be created instead. 3. 被动语态与主动语态的转换 主动语态：主语（动作执行者）+ 谓语 + 宾语（动作承受者） 被动语态：主语（动作承受者）+ be + 过去分词 + (by + 动作执行者) 注意：只有及物动词才有被动语态；不及物动词、连系动词等无被动语态。 主动：Alexander Bell invented the telephone in 1876. 被动：The telephone was invented by Alexander Bell in 1876. 4. 被动语态中常见介词短语 be made of 由……制成（看得出原材料） be made from 由……制成（看不出原材料） be made by 由……制造 be made in 在……制造 be used for 被用来（用途） be used to do 被用来做某事 be used by 被……使用 be connected to 被连接到…… be added by 被……添加 be sent to 被发送到…… be sent across 被发送穿过…… be invented by 由……发明 be introduced for the first time 首次被引入 be completed in 于……建成 be built to 被建造用来…… be allowed to do 被允许做某事 be praised for 因……被称赞 be responsible for 对……负责；是……的原因 be used to write on 被用来书写 be suitable to do 适合做某事 be dried and pressed 被干燥和压制 5. 重点动词短语与句型 bring about 带来；引起 find out 查明；弄清楚 be used to do 被用来做某事 be used to doing 习惯于做某事 used to do 过去常常做某事 connect...to... 把……连接到…… have a big effect on 对……有很大影响 make it + adj. + for sb. to do sth. 使某人做某事…… make sb. + adj. 使某人…… turn...into... 把……变成…… depend on 依赖于；取决于 be responsible for 对……负责；是……的原因 such as 例如 either...or... 要么……要么…… become interested in 对……产生兴趣 try to do sth. 试图做某事 be suitable to do 适合做某事 speed up 加速 not only...but also... 不仅……而且…… lead to 导致 result in 导致；造成 add...to... 把……加到…… come up with 想出；提出 apply for 申请 make the world a better place 使世界更美好 meet the requirements 满足要求 6. 词性转换与构词法 本单元重点词性转换： invent → invention → inventor → inventive create → creation → creative → creativity design → designer produce → product → production → productive collect → collection → collected develop → development → developing → developed introduce → introduction connect → connection → connected add → addition → additional use → useful → useless → used build → building act → active → activity → action → actor → react success → successful → successfully import → important → importance danger → dangerous effect → effective → effectively economy → economic tour → tourism → tourist operate → operation → operator educate → education → educational health → healthy real → reality → realize 7. 宾语从句的延续 本单元继续巩固宾语从句，包括 that / if / whether / wh- 疑问词引导的宾语从句。注意宾语从句用陈述语序。 例：Find out when they were invented. 例：Do you have any ideas about what will make the world a better place? 例：Cai Lun got the idea that bark, certain plants, and old clothes could be used to make a special material. 8. 形式主语与形式宾语 It is believed that... 据信…… It is + adj. + to do sth. 做某事是……的 make it + adj. + for sb. to do sth. 使某人做某事…… 例：It is believed that the world's oldest wheel was found in Eastern Europe. 例：The radio made it much easier for people to enjoy music from artists around the world. 9. 重要语法点：used 的三种用法 be used to do sth. 被用来做某事（被动语态，to 为不定式符号） be used to doing sth. 习惯于做某事（to 为介词） used to do sth. 过去常常做某事（表示过去习惯，现在已不如此） 例：Pipes were used to keep the ground hard. 例：I am used to getting up early. 例：I used to play football after school. 第 1 页 共 44 页 学科网（北京）股份有限公司 $
