文章大意：本文介紹了能使人們遠離鱷魚襲擊的無人機，它比人類的眼睛精確度更高，能在發(fā)現(xiàn)危險時發(fā)出警示信號。

【1】句意：高科技無人機在昆士蘭州附近沿著小溪、河床和沙灘進行測試。

結(jié)合句意“高科技無人機在昆士蘭州附近沿著小溪、河床和沙灘被____”及備選詞可推出此處用tested表示“測試”。故選E。

【2】句意：在昆士蘭州北部的旅游勝地，2017年和2018年間有五次包含兩致命襲擊的襲擊事件，和40公里外的內(nèi)陸中罕見的目擊事件。

根據(jù)題干中“____ two deadly attacks”可推出這兩次致命襲擊包含在五次襲擊之內(nèi)，結(jié)合備選詞可知要用including表示“包含”。故選A。

【3】句意：在飛行員操縱無人機的時候，視頻監(jiān)控，并在捕捉到下方危險信息時發(fā)回警告信號。

結(jié)合題干中“the pilot ____ the drone”及常識可知是由飛行員操控?zé)o人機，再結(jié)合備選詞可知用operates表示“操作；運行”。故選C。

【4】句意：設(shè)計人員說這項發(fā)現(xiàn)有93%的精確度，而人類的眼睛有16%~19%的正確率。

根據(jù)題干中while可知此處表示對比，再由“around 16 to 19 percent correct”可知此處要用與correct意思相近的詞語，結(jié)合備選詞可知用accurate表示“精確的”。故選D。
