However, when the Wright brothers flew the first airplane, Flyer 1, over a century ago, they used no ailerons but wires and pulleys that twisted the woodand canvas wings, to control the plane. Scientists have long sought to develop aircrafts that can alter their wings during flight, just as birds can. However, most previous attempts have failed because they relied on heavy mechanical control structures within .the wings. These structures were also plex and unreliable, said Neil Gershenfeld, a physicist and director of the Center for Bits and Atoms at Massachusetts Institute of Technology (MIT). The new wing consists of a system of tiny, strong, lightweight modules. The shape of the wing can be changed uniformly along its length using two small motors, which apply a twisting pressure to each wingtip. These wings are covered in “skins” of overlapping strips of flexible material resembling fish sizes. These strips move across each other as the wings alter, providing a smooth outer surface, the researchers explained. Windtunnel tests of these wings showed that they at least matched the aerodynamic properties of conventional wings, at about onetenth the weight. Initial tests using remotely piloted aircrafts made with these wings have shown great promise, said Benjamin Jet, a graduate student at the Center for Bits and Atoms at MIT. The new modular structures the scientists developed could be manufactured quickly in mass quantities and then installed by teams of small robots. These modular structures also can be disassembled more easily, making repairs simpler. “Still, the first aircraft built using this strategy will not be a passenger jet,” Gershenfeld said. “Instead, the technology will likely first be tested on unmanned aircraft, leading to drones (無人機 ) that can fly for a long time, to help deliver inter access or medicine to remote villages and do some rescue works.” 32. Why did most previous aircrafts fail to fly like birds? A. The previous wings were plicated and weighed a lot. B. The previous aircraft relied on ailerons to control directions. C. There were few scientists to do research on the lighter wings. D. There was little fuel in the aircrafts to make them fly in the air. 33. What is the fourth paragraph mainly about? A. The shape of the new wings. B. The result of the tested wings. C. The function of the small motors. D. The working principle of the new wings. 34. Which of the following can replace the underlined word “disassembled” in Paragraph 6? A. put away B. taken apart C. invented D. analyzed 35. What will the drones made by the new wings be firstly used to do? A. Carry passengers. B. Save people in danger. C. Test planes. D. Monitor the villages. 第二節(jié)（共 5小題 。選項中有兩項為多余選項。每小題 ，滿分 30分） 閱讀下面短文，從短文后各題所給的 A、 B、 C 和 D 四個選項中，選出可以填入空白處的最佳選項。每小題 ，滿分 15分） 閱讀下面短文，在空白處填 入 1個適當(dāng)?shù)膯卧~或括號內(nèi)單詞的正確形式。每小題 1分，滿分 10分） 假定英語課上老師要求同桌之間交換修改作文，請你修改你 同桌寫的以下作文。每處錯誤僅涉及一個單詞的增加、刪除或修改 。 刪 除 ： 把多余的 詞 用斜線（ \） 劃掉。 注意 ： ； 10處，多 者（ 從第 11處起）不計分。請你用英語寫一封回信，為他介紹春聯(lián)的用途、內(nèi)容和寓意等。 聽力： 1? 5 CAACC 6? 10 BCBAB 11? 15 CAACB 16? 20 CBAAB 閱讀理解： 2125 CDACD 2630 BACAC 3135 DADBB 七選五 ： 3640 BFCDA 完型填空 ： 4145 BDBAC 4650 DCBDA 5155 CBAAD 5660 ACDCB 語法填空： 61. attractive 62. is listed 63. distributed 64. or 65. freshly 66. which 67. to preserve 68. appearance 69. for 70. characteristics 短文改錯 ： 71. outdoor— outdoors 72. fortfortable 73. amused— amusing 74. leaf — leaves 75. endended 76. 在 video 前面加 a 77. begin— beginning 78. 刪掉 of 79. another— other 80. played— playing 范文： Dear Peter, I’m glad to know you have interest in Spring Festival couplets. Now, let me introduce some details of them to you. As a symbol of Chinese traditional culture, Spring Festival couplets are always stuck on the door or the wall of a house. They are necessities for Chinese people to celebrate the Spring Festival. Written with a writing brush on red paper, Spring Festival couplets use some positive words showing wishes for love, health, success, wealth, happiness and so on. They always have a theme, and they represent better life or successful future, and some of them include wishes and expectations. Of course, the topic of singing the praises of our motherland is another good choice. Yours, Li Hua
