1、高考英语复习备考：同源高考一修复师让化石“活” 了起来等3那么修复师让化石“活” 了起来化石被发现时通常被包裹在层层的岩石中，很少有人能认出它们是什么。修复师必须 移除周围的积物，才能让古老的生物尽可能呈现出最原始的状态。当然，这需要修复师们 极大的专注和耐心。Restorer Luo Yongming, 51， sits unmoving for almost an hour, staring into the microscope as he uses a pneumatic pen on a crinoids fossil. Crinoids are a family of marine
2、 animals that still exist today as starfish and sea urchins, and the part Luo is cleaning is only 3 to 4 centimeters long. For most people, the process is repetitive and boring, but not for Luo. Touching species from ancient times and trying to restore them to their original states is like talking t
3、o history and preserving ancestral memories. The more I restore, the more I feel the magic, he said.When Luo was young, he played in the mountains around the factory where his father worked. He found many stones containing fossilized insects, which first aroused his interest. He later studied mining
4、 at college and then joined a geological prospecting team after graduation.In 1998, a friend brought a crinoids fossil for restoration to the office next to Luos at the geological investigation research institute. Seeing the elderly researchers wearing reading glasses and trembling as they handled t

6、dvancean affordable prosthetic hand that not only responds like a real one to signals from the wearers brain, but is also able to signal back to the brain what it is touching and doing.The whole hand is covered with a flexible elastomeric （弹性体）layer to imitate skin and is attached to the users resid
7、ual limb. In contrast to current models, which are electrically powered, the new prosthetic hand is powered by a compressed air pump. This reduces its weight below 300 gramshalf that of some current models.The hand uses similar signal processing algorithms （算法）to other prosthetics on the market. The
8、 big advance is that it does not require invasive surgery or electronic implants into the residual limb to communicate with the users brain. Sensors on the skin record electrical signals from the remaining arm muscles. The signals then are interpreted by pattern recognition software that sends appro
9、priate commands to the pump to move the artificial hand. Meanwhile, other signals travel in the opposite direction from sensors in the hands fingertips to nerves in the arm, from which they are relayed to the brain and provide a sense of touch. The result is something which responds like a hand and
10、feels like one to the user.Dr Gu and his colleagues compared the efficacy of their invention with that of existing models using tests borrowed from research into strokes and spinal cord injuries. These included writing, grasping and lifting objects, and lifting food to the mouth. Normally, they foun
11、d it worked betterparticularly for delicate tasks like handling fragile objects, petting a cat and shaking hands.The other advantage of Dr Gu and his colleagues invention is that it is cheap. The components it is made from cost about $500. Existing models may sell for $10, 000 or more. If it goes in
12、to production, that will permit the transformation of many more of the lives of the people who have lost a hand, or were born without one.Reading check1. What makes the prosthetic hand an advance?A. Its shape. B. Its functions.C. Its structure. D. Its skin.2. Whats the advantage of the power system

16、 the ban d age? This is a difficult problem, because removing a bandage can damage the healin g process. Technology presented in a new study could help.This new smart bandage contains a sensor that can sensitively measure wound moi s ture levels and then transmit the data to a nearby smartphone, wit
17、hout requiring doct ors to remove the bandage. By changing the geometry and materials in the bandage, u sers may be able to adjust it to suit different types of wounds. The technology could help doc tors to monitor wounds more easily and successfully.Chronic wounds can be a source of significant suf
18、fering and disability for patients wh o experience them. Getting such wounds to heal is tricky and there are many factors that can affect wound healing. However, one of the most important is moisture levels. If the wound is too dry, the tissue can become dry; if the wound is too wet, it can become w
19、hite and wrinkly. However, if a doctor wants to check the moisture levels of a wound ,then he or she needs to remove the bandage, potentially damaging the delicate hea ling tissue. These issues have inspired this latest smart bandage.The choice of materials was a challenge, so researchers applied a
20、special material onto a gauze （纱布）using a technique called screen printing, and then connected the gauze with commercially available bandage materials. The idea is that changes in the moisture levels of the wound cause a change in an electronic signal measured by the sensor.To test their bandages, t
21、he researchers exposed them to artificial wound liquid, a nd also tested different bandage materials and shapes. They found that the bandage wa s highly sensitive, providing different readings in different conditions, suggesting it co uld be a valuable tool in wound management.“We developed a range
22、of bandages with various layers and different absorption pro perties and characteristics, said Dr Luca Toscanini, one of the researchers. The ide a is that each type of wound could have its own appropriate dressing. However, we will need to further perfect the sensor geometry and determine the appro
23、priate sensor value s for the best healing before we can apply our technology to various types of wounds.”1. What does paragraph 2 mainly talk about the smart bandage?A. Its popularity.B. Its wide application.C. Its working mechanism.D. Its complex structure.2. Whafs the key factor that influences w

Convenient. D. Flexible.4. What can we infer from what Dr Luca Possanzini said in the last paragraph?A. There is a
25、 variety of bandages available.B. The smart bandage still needs improving.C. Bandages contribute to the healing of wounds.D. The smart bandage should be used appropriately.Difficult sentences in the text1. However, if a doctor wants to check the moisture levels of a wound, then he or she needs to re
26、move the bandage, potentially damaging the delicate healing tissue.然 而，如果医生想检查伤口的湿度，他们就需要取下绷带，这可能会破坏脆弱的愈合组织。【点石成金】句中 if a doctor wants to check the moisture levels of a wound 为 if 弓I 导的条件状语从 句，potentially damaging the delicate healing tissue 为结果状语。2. The idea is that changes in the moisture levels of the wound cause a change in an electronic signal measured by the sensor.其原理是，彳募口湿度的变化会引起传感器测量 到的电子信号的变化。【点石成金】句中that引导表语从句，that在从句中不作成分，没有实际含义，但不能省略;measured by the sensor为修饰signal的后置定语。答案：修复师让化石“活” 了起来1 4CDAA新型智能义肢1 4 BABB智能绷带1-4CDCB
