D
Plains - wanderers are small, rare birds that live in the grasslands. Unlike most birds, female plains - wanderers are larger and stronger than males. Females take the lead in protecting their nests and babies from animals like foxes, while males often sit on the eggs to keep them warm. These birds are hard to find because their feathers blend into the grass, making them look like part of the landscape. Sadly, their numbers have been dropping because people are taking over their grassland homes for farms and cities.
To save them, scientists are using AI. The key is the birds' calls. Mother plains - wanderers make soft sounds to talk to their chicks and warn about danger. These calls are quiet and easy to miss, but AI can hear them clearly. Scientists put special recording devices in the grasslands to record sounds all day and night. Then they put these recordings into a computer program. AI learns to tell the birds' calls apart from other noises, like the wind blowing or insects chirping. This helps scientists find where the mother birds are and how many chicks they have.
"AI helps us monitor these birds without bothering them," says Mr. Hartnett, one of the scientists. "We can find the most important areas for them and work to protect those places. " Once, AI helped scientists find a hidden nest with three baby birds. Without AI, they might not have found it. Thanks to this technology, there is new hope for these rare birds, showing that AI can be a powerful tool in saving wildlife.
12. What do we know about plains - wanderers?
A. Males are larger than females.

答案:
12 C 【解析】细节理解题。根据第一段中的“female plains-wanderers are larger and stronger than males”及“Females take the lead in protecting their nests and babies from animals like foxes”可知,母鸟体型较大,并在保护巢穴和幼鸟方面发挥领导作用。故选C。
13 D 【解析】词义猜测题。根据画线词后的“We can find the most important areas for them”和“Once, AI helped scientists find a hidden nest with three baby birds”可知,画线词所在句是说人工智能能够帮助监测领鸺鹠,同时又不会打扰到它们,故monitor意为“监视,跟踪调查”,与follow词义相近。故选D。
14 D 【解析】细节理解题。根据第二段中的“To save them, scientists are using AI. The key is the birds’ calls”和“AI learns to tell the birds’ calls apart from other noises…This helps scientists find where the mother birds are and how many chicks they have”可知,人工智能通过分析鸟鸣的叫声来寻找领鸺鹠。故选D。
15 D 【解析】主旨大意题。通读全文,尤其是文章最后的“Thanks to this technology, there is new hope for these rare birds”可知,本文主要介绍了科学家利用人工智能技术保护领鸺鹠的创新方法。D选项(科学家如何利用人工智能来保护领鸺鹠)符合文意。故选D。
