The artificial sensor is multi­layered.One layer acts as a transmitter (发射器), which will generate an electric field once activated, and another layer acts as a receiver to detect both the direction and the distance to an object.A separate controller creates the driving signal to activate the transmitter.When an object comes within range, the electric field around the sensor is disrupted, which in turn can be detected by the receiver.This data is then processed by a microcontroller unit, which computes the position of the target object and sends that information to a smartphone or other devices. A special biogel (生物凝胶) is used in the sensor, which has the ability to transmit and receive electric signals from a pattern of microchannels on the surface.The end result is a sensor that is thin, soft and flexible, making it easy to adapt to irregular surfaces, such as the human body.In contrast to the traditional sensor system that needs a large number of sensors to achieve spatial positioning, the new system can locate an object precisely in 3D space using just a few sensors.This significantly reduces the power consumption of data collection, transmission, and processing. The researchers hope that this sensor could one day open up a new range of wearable technologies, including sensors for human­machine interaction and thin, flexible e­skin. [语篇解读]本文是一篇说明文。文章讲述了受非洲电鱼特殊能力的启发，科学家开发出一种人造传感器系统，并阐述了其原理、优势及应用前景。 4．The first paragraph aims to show ． A．the special ability of African fish B．the inspiration for a new invention C．the big challenge of locating objects D．the reason for developing a sensor 解析：选B。推理判断题。根据第一段可知，第一段先介绍了非洲电鱼的特殊能力，接着说明科学家基于此开发出人造传感器系统，所以第一段旨在展示一项新发明的灵感来源。故选B。 5．What does the underlined word “disrupted” in Paragraph 3 mean? A．Disturbed. B．Arranged. C．Enhanced. D．Stabilized. 解析：选A。词句猜测题。结合常识和画线词所在句“When an object comes within range, the electric field around the sensor is disrupted, which in turn can be detected by the receiver.”中“be detected by the receiver”可推知，物体进入传感器范围时，电场被干扰，才会有信号被接收器检测到。所以画线词意为“干扰，扰乱”，与“disturbed”意思相近。故选A项。 6．What is an advantage of the new sensor system? A．Its sensitivity to different stimulations. B．Its adaptation to environmental changes. C．Its efficiency in achieving 3D positioning. D．Its speed in data collection and processing. 解析：选C。细节理解题。根据第四段中“In contrast to the traditional sensor system that needs a large number of sensors to achieve spatial positioning, the new system can locate an object precisely in 3D space using just a few sensors.This significantly reduces the power consumption of data collection, transmission, and processing.”可知，新传感器系统的优势在于它在实现三维定位方面的高效率。故选C。 7．What is the best title for the text? A．Machine Detective “Wears” Flexible E­skin B．Bio­inspired Sensor “Feels” Without Touching C．E­Skin Sensor: The Future of Machine Learning D．Electric Fields: The Frontier of Object Detection 解析：选B。标题归纳题。根据第一段以及第二段可知，文章主要讲述了受非洲电鱼特殊能力的启发，科学家开发出一种人造传感器系统，这种传感器不用触摸就能“感知”物体。B项“Bio inspired Sensor ‘Feels’ Without Touching(受生物启发的传感器不用触摸就能‘感知’)”能概括文章主要内容，最适合做文章标题。故选B。 Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2025·云南西双版纳期末)Have you been wishing to put on your hiking shoes and enter the woods for a little backpacking (背包) trip, but you' re not sure exactly where to start?
