Anticipating a drier future, two American teen engineers have been investigating how to help farmers keep their crops from getting dangerously thirsty. John Benedict, 16, has seen lots of droughts. As a sophomore at Clovis North High School, he wanted to help farmers save their plants from being dried. To measure a plant􀆳s drought stress more directly, he built a small robotic arm and used it to measure the light reflecting off of bell peppers. As plants get dry, the way they reflect sunlight changes very slightly. It􀆳s not something that our eyes can see. But it is something a robot could detect. At the same time, his robot measured soil moisture and temperature. With these data, he built a computer model. It predicts which plants will be suffering from thirst faster. It􀆳s also important to make sure that no irrigation water is wasted. That􀆳s why Arya Tschand, 17, has been launching his drone into the sky. This senior at High Technology High School, aims to help poor farmers like the ones he saw while traveling in India. The teen􀆳s drone hovers over plants and measures their color. Using a computer model, Arya taught the drone to predict how thirsty a plant was based on the color of its leaves. According to that color, the drone then sends a signal to an irrigation system on the ground, which adjusts how much water it sends out to plants. In areas with drought, where every drop matters, farmers can􀆳t afford to waste any moisture.Just like John, his next step is to scale up his project. In the meantime, he has applied for a patent on his system. 本文主要介绍了John Benedict和Arya Tschand开发的两种帮助农民防止作物陷入危险的干旱的技术。 1.What did John focus on in his project? A. Plants management. B. Data analyses. C. Plant⁃thirst detection. D. Lights changes. 答案与解析　C　细节理解题。由第二段最后三句“他的机器人测量土壤湿度和温度。有了这些数据,他建立了
