Australia is home to crocodiles. Thanks to world-first drones(无人机), people are safer from crocodile attack.

The high-tech drones were 【1】 near Queensland, along creeks, riverbeds, and beaches. They are trying to find out animals as they went.

There were five attacks in Queensland’s touristic north between 2017 and 2018, 【2】 two deadly attacks, and unusual sightings more than 40 kilometers inland.

The technology solution came from using newly developed shark-spotting drones to find out another kind of animals. As the pilot 【3】 the drone, the video is monitored and a warning message is sent back to the pilot when it picks up on something dangerous below.

Designers say the finding is 93 percent 【4】, while human’s eye is around 16 to 19 percent correct.

“A lot of time above crocodiles, a lot of images fed into the program as it’s a learning program, which means it then gets better at spotting,” the designer said.

【答案】

【1】E

【2】A

【3】C

【4】D

【解析】

文章大意：本文介绍了能使人们远离鳄鱼袭击的无人机，它比人类的眼睛精确度更高，能在发现危险时发出警示信号。

【1】句意：高科技无人机在昆士兰州附近沿着小溪、河床和沙滩进行测试。

结合句意“高科技无人机在昆士兰州附近沿着小溪、河床和沙滩被____”及备选词可推出此处用tested表示“测试”。故选E。

【2】句意：在昆士兰州北部的旅游胜地，2017年和2018年间有五次包含两致命袭击的袭击事件，和40公里外的内陆中罕见的目击事件。

根据题干中“____ two deadly attacks”可推出这两次致命袭击包含在五次袭击之内，结合备选词可知要用including表示“包含”。故选A。

【3】句意：在飞行员操纵无人机的时候，视频监控，并在捕捉到下方危险信息时发回警告信号。

结合题干中“the pilot ____ the drone”及常识可知是由飞行员操控无人机，再结合备选词可知用operates表示“操作；运行”。故选C。

【4】句意：设计人员说这项发现有93%的精确度，而人类的眼睛有16%~19%的正确率。

根据题干中while可知此处表示对比，再由“around 16 to 19 percent correct”可知此处要用与correct意思相近的词语，结合备选词可知用accurate表示“精确的”。故选D。
