9、inithologists （鸟类学家），a small bird can look much like another. But luckily, researchers have built an artificial intelligence （AI） model. Our study provides the means of overcoming one of the greatest 1 imitations on the study of wild birds-reliably recognizing individuals. said Andre Ferreira, lead

10、author of the study.Ferreira began exploring AI * s potential while in South Africa, where he studied the sociable weaver, a bird which works with others to build the world s largest nest. Ferreira wanted to understand each individual * s contribution to building the nest, but it was hard through di

11、rect observation because they were often hiding in trees or building parts of the nest out of sight. This experience contributed to his building the AI model, which could recognize individual birds simply from a photograph of their backs while they were busy with nest-buiIding.The model must be trai

12、ned with thousands of labeled images in order to accurately identify individuals, but cicquiring labeled photographs of biids is very difficult. Ferreira and other researchers finally overcame this challenge. They built feeders with camera traps and sensors. Most birds in the study populations alrea

13、dy carried a tag （标签）similar to microchips which are put in cats and dogs. Antennae （天 线）on the bird feeders read the identity of the bird from these tags and touched off the cameras.According to Ferreira, the use of the Al model could save on expensive fieldwork and spare researchers from procedure

14、s such as catching and marking animals. It removes the need for the human to be a data collector, so researchers can spend more time thinking about the questions instead of collecting the data, “ said Ferreira.The AI model is currently only able to re-identify individuals that have been shown to it

15、before. The researchers are now trying to build more powerful AI models that can identify larger study groups of birds, and distinguish individuals even i f the Al mode 1 have never seen them before. This would enable new individuals without tags to be recorded by the cameras and recognized by the c

30、irdsreliably recognizing individuals.（我们的研究为克服野生鸟类研究中的个最大限制一可靠地识别个体一提供了手段。）“ 中的reliably recognizing individuals可知，在研究野生鸟类时，“准确地识别鸟类” 是最困扰鸟类学家的。故选C项。17 .推理判断题。根据第二段“This experience contributed to his bui Iding the AI model, wh ich cou I d recogn ize i nd i v i dua 1 bi rds simply from a photograph of

31、 the i r backs while they were busy with nest-building.（这种经验有助于他建立人工智能模型，这种模型可 以简单地从一张鸟类背部的照片中识别出它们正在忙于筑巢的个体。）”中的which引导的 非限制性定语从句提到的各种AI模型的好处可推知，提到Ferreira在南非研究鸟儿的经历 是为了说明AI模型的好处，即研究AI模型的原因。故选D项。18 .词句猜测题。根据前文“The model must be trained with thousands of labeled images in order to accurately identi

32、fy individuals, but acquiring labeled photographs of birds is very difficult.（为J准确地识别个体，模型必须经过成千上万张标记图像的训 练，但是获取标记鸟类的照片是非常困难的。）”可知，获得鸟类的标记图像是一件很难的 事情。difficult与challenge,词性不同，但意思相近,故this challenge指代的是“获 得标记鸟类的图片”这件事。故选B项。19 .推理判断题。根据最后一段 uThc researchers are now trying to buiId more powerful AI mode
