Question

【题目】根据短文理解，选择正确答案。
Since 2008, hunters have illegally killed more than 3000 rhinos in South Africa. The International Union for Conservation of Nature warns that rhinos may die out by 2026. People who hunt and kill illegally are called poachers. The most effective way to watch for and prevent illegal hunting is from the air. However, piloted flights are too costly. Fortunately, some Spanish college students have invented a drone (无人机) that can observe more places than a plane.
Arnau Garcia is an aeronautical (航空学的) engineering student at the Polytechnic Institute of Catalonia, in Spain. He says observers from the air have trouble finding poachers when they hide under the trees. Mr. Garcia and other students have worked with the drone manufacturer HEMAV to help find the hidden poachers. They make it by using the thermal camera, which is especially sensitive to body heat. Even when the poachers keep still, it can also keep track of them.
The drone can fly in the wind up to 55 kilometers per hour. It has an autopilot system, so it memorizes the flight path. The drone also has a microphone, a video camera and a GPS system. These permit it to report accurately where a picture is taken. After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.
Experts say the drone can fly as far as 70 kilometers from the base. It means that it could quickly observe large areas for poachers. However, the same search operation would take days for human observers. Thanks to the drone, many poachers have been caught and the number of rhinos is on the increase. In addition, HEMAV has received an increasing number of orders for the drone. Even South African national park officials attempt to fill the air with drones.
（1）What do we know about the drone? _____
A.It may get lost easily in the air.
B.It can't work in the windy days.
C.It can offer detailed information.
D.It is useless when the poacher stays still.
（2）What's the best title for the text? _____
A.How to make the drone work well
B.A new way to stop illegal hunting
C.The living conditions of rhinos are worrying
D.The drone helps save rhinos in South Africa

Answer 1

【答案】
（1）C
（2）D
【解析】无人机帮助保护犀牛。

（1）C细节理解题。根据第三段第五句After each flight, the drone can bring back detailed information每次飞行之后，无人机能带回详细的信息。故选C。

（2）D主旨大意题。根据第一段第二句The International Union for Conservation of Nature warns that rhinos may die out by 2026.到2026年犀牛可能灭绝。第六句some Spanish college students have invented a drone (无人机) that can observe more places than a plane. 西班牙大学生发明了无人机，能观察更多地方。第三段最后一句After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.每次飞行之后无人机能带回详细信息，在哪里能找到犀牛，在这个地区水和植物的条件状况和嫌疑偷猎者的位置。可知D项符合题意。
