Their many uses include taking pictures from the sky, watching wild animals and sending packages of goods. Now these small flying robots are leading a big change in farming. With cameras and some data-collecting devices, drones provide us with an eye in the sky. Here are a few of the farming jobs drones can do. Looking for sick crops Drones can scan crops using different kinds of light. In this way, they carefully examine the fields and produce detailed pictures that can help us find sickly yellow plants within fields of green. Drones can also check for bacteria that are harmful to crops in the air from a few kilometers away, so that farmers can try to find ways to protect their crops before the bacteria get to them. Water watch Most fields aren't perfectly flat. There might be hills, slopes and holes. After watering, some places may dry out faster. Some spots might not get water at all. Drones can scan the field and make a 3-D map. Using the map, farmers can find out which parts of a field are dry or need improvement. This can make sure every crop can get enough water to stay healthy. Spraying pesticide(喷洒农药) Different parts of a field might have different heights. Drones can check for this when flying above the land. Then, they change their height and therefore spray the correct amount of pesticide over each part of the field. This way works much better than traditional pesticide spraying. Drones can finish spraying a field up to five times faster than with traditional machinery, according to a study. This can stop insects from damaging the crops in a shorter time. 26. How many farming jobs done by drones are introduced in the passage? A. 3 B. 4 C. 5 D. 6 27.
