专题15 阅读理解之说明文 例1 （2022·江苏南通·统考中考真题）Technology and sustainability(可持续性) are two driving forces in the world today. For the agriculture department, sustainable agriculture technology must be the new trend, and farmers should follow it. The following sustainable agriculture technologies are necessary. Smart irrigation Crops need water—that’s needless to say. However, how they get water is another story. With smart irrigation technology, water can be put to good use. New irrigation systems with smart technology can report soil moisture(湿度) and temperature in real time. These new technologies help farmers properly take care of crops in a more efficient way. For example, most crops have specific requirements for temperature and moisture. The new irrigation systems can show farmers whether they need to make changes for their crops’ growing environments. In this way, they may help reduce the waste of water. Drones Drones’ abilities get them a place on this list. They can do a lot and most importantly, they can make the boring and tiring farm work much easier. These devices have high-definition cameras that take pictures and videos. Through wireless control, just at home farmers can fly the drones over the fields and check on crops. If one area of crops isn’t doing well, farmers can quickly record the details and then spray chemicals with the help of the drones. Data and software Data is rich in this tech-driven world. Farming and data working together can greatly change the way farmers plant, harvest and water. As computers gather information, they report it all back to a central system. So when farmers learn in which area crop health needs to improve, they can use water and fertilizer(肥料) more efficiently, causing less waste. The three technologies are helpful for farmers to save costs, labor and energy. And they can contribute to the final goal of agricultural sustainability—that is to improve the environment. As these new technologies continue to develop, we are sure
