1.C.Read the passage and fill in the blanks with proper words
Recently the unmanned aircraft which are called drones (無人駕駛飛機)have come into use for a number of business purposes.Basically,a drone is a flying robot.The aircraft (飛行器) may be remotely controlled or can fly a(81)utomaticallythrough flight programs in their systems.The little planes used to be very costly.In the past,they were mostly used in the military (軍事).But as they have d(82)ropped in price more people have begun 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.The fast development of computer technology,image sensing devices (圖象感應設備),satellite navigation (衛星導航) and cell phones has led to lower-priced drones.Researchers and developers have learned how to build smaller and less-costly drones.Moviemakers are using drones to film from the sky.Historians (歷史學家.) use them when they explore a(83)ncient buildings.Rescue workers use them to look for people:And now farmers are using them to m(84)onitor their crops.
Romain Faroux is a French businessman who starts companies.His father was a farmer.He believed drones could help farmers.He helped create a company that developed a small drone that could be controlled by people on the g(85)round.They called it"Agridrone (農業無人機).''It uses a special"optical sensor (光學感應器 )"to examine crops.
The technology used is similar to that used by smart phones except it has wings.A computer program directs the drone to fly over the crops.The sensor on the drone records four different-colored"bands"of sunlight ( 太陽光帶) that are reflected off ( 反射 ) the crops.
Jean-Baptiste Bruggeman is a farmer.He says the drone flies over his crops at different time of the season.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)athered/got.by the Agridrone to place fertilizer only in areas where it was needed.This saves money and reduces pollution.Before they used the drones,farmers would put the same amount of fertilizer everywhere.Drones also save time because farmers can examine u(87)p to three hectares (公頃) in about a minute.
