Recently the unmanned aircraft which are called drones (無人駕駛飛機(jī)) 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 【1】________ through 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 【2】________in price more people have begun to use them. Rescue workers and fanners 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 (圖像感應(yīng)設(shè)備), satellite navigation (衛(wèi)星導(dǎo)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(xué)家) use them when they explore a 【3】________. buildings. Rescue workers use them to look for people. And now farmers are using them to m【4】________their crops.

Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help fanners. He helped create a company that developed a small drone that could be controlled by people on the g【5】________ . They called it “Agridrone (農(nóng)業(yè)無人機(jī)).” It uses a special “optical sensor (光學(xué)感應(yīng)器)” to examine crops.

The technology used is similar to that used by smartphones 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 this 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 【6】________ 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 【7】________ to three hectares (公頃) in about a minute.

【2】dropped

【6】gathered/got

【7】up

【解析】

試題分析：這篇短文主要講了關(guān)于無人飛機(jī)的情況。

【1】上下文暗示題。首先可判斷詞性為副詞。另上下文提到由于無人駕駛飛機(jī)通過輸入的程序即可飛行，故無人飛機(jī)可以自動(dòng)地飛行。根據(jù)語境及開頭首字母此空應(yīng)填automatically。

【2】上下文邏輯題。首先可判斷此處是一個(gè)現(xiàn)在完成時(shí)，故應(yīng)填一個(gè)動(dòng)詞的過去分詞。另由于上文說到之前無人駕駛飛機(jī)花費(fèi)高昂，故在轉(zhuǎn)折詞后應(yīng)填一個(gè)表示價(jià)格下跌的動(dòng)詞。根據(jù)首字母此題應(yīng)填dropped。

【3】歷史學(xué)家使用無人駕駛飛機(jī)一般是需要探索古代的、古老的建筑。根據(jù)分析及所給首字母此題應(yīng)填ancient。

【4】根據(jù)語境農(nóng)民可以用無人機(jī)監(jiān)控他們的莊稼。所以此題應(yīng)填monitor。

【5】固定搭配題。on the ground在地上。此處指的是人們可以在地面上操控?zé)o人駕駛飛機(jī)。所以填ground。

【6】信息是被“搜集”或“得到”的，故根據(jù)首字母能想到gather，又因?yàn)榇颂幨潜粍?dòng)語態(tài)，需變形為過去分詞。所以填gathered/got。

【7】根據(jù)語境及固定搭配up to（多達(dá)）可知此題應(yīng)填up。
