Read the passage and fill in the blanks with proper wordsRecently the unmanned aircraft which are called drones （无人驾驶飞机）have come into use for a number of business purp

55、oses. Basically, a drone is a flying robot. The aircraft (飞行器) may be remotely controlled or can fly a 81 through flight programs in their systems. The little planes used to be very costly. In the past, they were mostly used in the military (军事) . But as they have d 82 in price more people have begu

56、n to use them. Rescue workers and farmers are among the new users.A company in France is using drones to help farmers examine their crops and limit the amount of fertilizer ( 肥料 ) they use.

He says ttfis provides a lot of information about his crops. The drone pictures show him the exact amount of fertilizer the crops need. It also shows exactly where the fertilizer is needed. Romain Faroux says farmers use information g 86 . by the Agridrone to place fertilizer only in
