Each leg of the SNAG has two motors, one for helping it move back and forth, and the other one for grasping.Twenty printing attempts were necessary for the robot to finally reach its current structure, but it was worth it.Now, according to researchers, the flying machine has an impressively strong and high­speed clutch (离合器), being able to land and wrap its claws around a branch in about 20 milliseconds.SNAG has ankles lock, and there's an accelerometer (加速度计) on its right foot that reports that it's landed while triggering (触发) a balancing process to stabilize it. Scientists have already conducted several tests with the robot in rural areas and on different surfaces.In all the situations, the SNAG was able to catch objects thrown by hand, such as bean bags, a tennis ball, and more. As for the applications of the bird­like robot, the SNAG can get attached to drones (无人机) and be used for search and rescue missions, wildfire monitoring, to offer just a few examples.Another great application is environmental research, with the SNAG also featuring a temperature and humidity (湿度) sensor.By using a robot that can act like a bird, you can unlock new ways of studying the environment, as explained by William Roderick, mechanical engineer and one of the researchers involved in the project.Now scientists are moving on to improving the robot's situational awareness and flight control. This isn't the first time that nature has inspired groundbreaking technologies.We also wrote a piece recently about the F­SAM micro drone, which was inspired by the flight of samara (翼果) seeds, also known as “twisters” which have a special way of spinning down to the ground. [语篇解读]　本文是一篇说明文。主要介绍了一个带有小型爪子的鸟类仿生机器人，它不仅可以模仿鸟类飞行，停留在各种物体表面上，还可以捕捉和携带物体。 1．What gave the researchers inspiration for the SNAG's development? A．The plane.　　　 B．The falcon. C．The micro drone. D．The samara seeds. 解析：B　[细节理解题。根据第一段末尾句“...just like the mighty falcon(隼)that was used as the source of inspiration in its development.”可知，研究人员研发SNAG鸟类仿生机器人的灵感来自隼。故选B。] 2．What's the function of the accelerometer on the SNAG? A．To balance the SNAG in flight. B．To change the SNAG's flying speed. C．To keep the SNAG's feet in balance. D．To make the SNAG steady on a surface. 解析：D　[推理判断题。根据第二段末尾句“...there's an accelerometer(加速度计)on its right foot that reports that it's landed while triggering (触发) a balancing process to stabilize it.”可知，SNAG的右脚安装的加速度计在它降落在物体表面时会触发一个平衡系统，从而使SNAG能够稳定地降落在物体表面。故选D。] 3．What does Paragraph 4 mainly tell us about the SNAG? A．The SNAG has huge potential for practical use. B．The SNAG has a long way to go before being used. C．The SNAG will be helpful in putting out forest fires. D．The SNAG is sensitive to temperature and humidity. 解析：A　[主旨大意题。根据第四段第一句“As for the applications of the bird­like robot...”，第二句“Another great application is environmental research...”，第三句“By using a robot that can act like a bird...”和第四句“Now scientists are moving on to improving the robot's situational awareness and flight control.”可知，第四段主要讲述了SNAG这项发明所蕴含的巨大实用价值。故选A。] 4．What may be one disadvantage of the SNAG right now? A．It doesn't know its situation well. B．It can't fly fast enough in the air. C．It is easily broken by the branches. D．It can't catch objects with smooth surfaces. 解析：A　[推理判断题。根据第四段末尾句“Now scientists are moving on to improving the robot's situational awareness and flight control.”可知，研究人员现在正努力改善SNAG的环境感知能力和飞行控制系统。故选A。] B In ancient times, our ancestors relied on stars to guide them on a clear night. Today, we have navigational systems to help us find our way, with the latest being the Beidou Navigation Satellite System (BDS)． The BDS is entirely built by Chinese engineers. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing full­scale global services. It's difficult to imagine the great impact those satellites, orbiting (围绕……运转) the Earth, have on our daily lives. When you unlock one of Hellobike's bicycles, you are using the BDS. The popular bike­sharing company came out with two new bike models this year that are equipped with the positioning service.“The intelligent lock on each bike receives Beidou satellite signals and sends positioning information to the data center，which will help collect big data on the bikes and estimate users' riding demands in advance according to the data，” Chu Yiqun, a manager of Hellobike told Xinhua News Agency. Users can also find shared bikes more accurately thanks to Beidou's global positioning accuracy of 2.34 meters. However, the BDS doesn't just work one way. As the country's largest space­based system and one of four global navigation networks, along with the United States' GPS, Russia's GLONASS and the European Union's Galileo, Beidou adopts a unique two­way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously，this exclusive function isn't designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked. After the Wenchuan earthquake in 2008, all ground­based communication facilities (设施) were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between affected areas and rescue centers was successful. Now, Beidou's messaging capacity (能力) has been increased to 1200 Chinese characters in a single message.It is widely used in disaster alarms, automatic identification (识别) and information release. As Sun Jiadong, former chief designer of the BDS said：“The application of Beidou is only limited by imagination.” [语篇解读]　本文介绍了中国的北斗卫星导航系统。北斗的服务范围只受想象限制。 5．What can we learn about the BDS from the article? A．It was co­developed by Chinese and American engineers. B．It works better when the weather is good. C．Its last satellite was launched on July 31. D．It's able to provide global coverage for navigation. 解析：D　[细节理解题。由文中第二段可知D项正确。] 6．Why does the author mention Hellobike in Paragraph 3? A．To highlight the high positioning accuracy of the BDS. B．To show how the BDS makes people's daily lives easier. C．To present the benefits and limitations of the BDS. D．To explain how the BDS works. 解析：B　[推理判断题。由文中第三段可知，北斗使日常生活更加容易。] 7．What is the function of Beidou's two­way communication system? A．To help people when communication signals are poor. B．To make communication more fun. C．To allow users to chat online more freely. D．To collect feedback from users. 解析：A　[细节理解题。由第四段可知A项正确。] 8．What does Sun Jiadong imply in the last paragraph? A．Beidou may be more helpful than we know. B．Beidou stimulates users' imagination. C．Beidou needs to be further perfected. D．Beidou is limited in application. 解析：A　[推理判断题。由最后一段可知北斗的服务范围只受想象力限制，故选A项。] Ⅱ.完形填空 Rockets were probably invented by accident about 2,000 years ago.The Chinese had a form of gunpowder which was put in bamboo tubes and thrown into fire to make 　__1__　 during festivals.Perhaps some of the tubes jumped out of the fire instead of exploding in it.The Chinese 　__2__　 that the gunpowder escaping from the tube could lift it into the air.The idea of the rocket was 　__3__　.
