2、 developed machine learning tools to track the faces of individual wild chimpanzees(黑猩猩)Dan Schofield said that the system was developed to improve the quality of information collected about chimpanzees in the wild over a long period of time.“For species like chimpanzees,which have complex social li
3、ves and live for many years,getting snapshots of their behavior from shortterm field research can only tell us so much,” Schofield said.The researchers wanted to get a more complete understanding of the lives of the chimpanzees by studying them over several generations.But doing this would have requ
4、ired searching through hundreds of hours of video recordings of chimpanzees in the wild.The researchers recorded the activities of a group of chimpanzees that lived in the West African nation of Guinea.A facial recognition computer model was trained using more than 10 million images of the animals.T
5、he model was then used to search,recognize and track individual chimpanzees.The system was able to identify individual chimpanzees correctly about 92 percent of the time.It successfully identified the animals sex 96 percent of the time.The study included an experiment with humans to see how they cou
6、ld perform against the machine learning system in making identifications.The human persons were able to correctly identify individual chimpanzees about 42 percent of the time.The machine learning tool was much faster at completing the experiment.Human experts took about 55 minutes,while the computer
7、 took only seconds.The researchers say they are permitting other scientists to use the system for similar projects. hey hope the method will be used with other species to record animal behavior and monitor different animal populations in the environment.语篇解读本文是一篇说明文。文章主要介绍了人脸识别技术不但用来识别人类,而且还被应用于识别动物
8、,从而帮助科学家们更好地研究动物的情况。1What can we infer from Schofields words?AResearching chimpanzees needs more information.BChimpanzees can live as long as humans.CChimpanzees like to get snapshots too.DShortterm field research provides more information.解析:细节理解题。根据第三段中的“For species like chimpanzees,which have com
9、plex social lives and live for many years,getting snapshots of their behavior from shortterm field research can only tell us so much,Schofield said.”可知,像黑猩猩这样的生物,它们具有复杂的生活,并且寿命长,因此研究它们需要更多的信息。答案:A2What does the underlined word “this” refer to?ARecording the chimpanzees in the wild.BStudying chimpanz

11、。答案:C3What did the experiment with humans prove in the study?AHumans make more accurate identifications.BThe machine learning system is more effective.CHumans cant identify the animals sex correctly.DMachine learning tools take a little more time in identification.解析:推理判断题。根据倒数第二段“The study included
12、 an experiment with humans.Human experts took about 55 minutes,while the computer took only seconds.”可知,通过在人类身上做实验可知,机器学习系统无论是在时间上,还是在正确率上,识别都更加有效。答案:B4What is the best title for the text?AFacial Recognition for Animals Is Becoming PopularBFacial Recognition Is Helping Animals Live in the WildCFacia
13、l Recognition Plays a Role in Raising AnimalsDFacial Recognition Is Used to Identify and Follow Animals解析:标题归纳题。本文主要介绍了人脸识别技术在新领域中的应用。科学家们把它利用到研究动物上,从而能够更好地获得信息等情况,因此D项符合主题。答案:DB(2020湖南长郡中学三模)Luke GrenfellShaw has a rare form of cancer.It started as a pain in his shoulder and the tumour spread to hi
