23、as a number of later learners. Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference was. “Our findings suggest that the structure of the brain

24、is changed by the experience of learning a second language，” said the scientists. It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you t

32、为最佳答案。DA US government study has found that facial recognition technology is getting better at identifying people wearing masks. The study is part of an ongoing research by the US National Institute of Standards and Technology (NIST). The agency has examined the effectiveness of more than 150 facial

33、 recognition systems on people wearing face coverings . The systems are powered by machine learning algorithms (算法). The first results of the study were announced in July, as health officials across the world urged people to wear masks to limit the spread of COVID-19. New findings were released this

34、 week . Police agencies have long used facial recognition technology to search for and help catch criminals. It can also be used to unlock phones or other electronic devices. Some robots use facial recognition technology to recognize the people they are communicating with. However, the wide use of m

35、asks in public has created major difficulties for such systems. The study looked at facial recognition systems already in use before the pandemic. It also looked at systems specially developed to work on masked faces. The NIST said it processed a total of 6. 2 million images for the experiment Peopl

36、e in the images were not actually wearing masks. So, the researchers digitally added different mask shapes to faces in the pictures for use in the study. In some cases, up to 70 percent of a persons face was covered in the images. Overall, the research shows the top-performing facial recognition sys

37、tems fail to correctly identify unmasked individuals about 0. 3 percent of the time and the failure rate rose to about 5 percent with masked images. Many of the lower performing algorithms, however, had much higher error rates with masked images as high as 20 to 50 percent. In the latest findings, r

38、esearchers included results from 65 new facial recognition systems that have been developed since the start of the pandemic. “Some of these systems performed “significantly better” than the earlier ones，” Mei Ngan, a lead researcher on the project, said in a statement. The study also found round-sha

39、ped masks which cover only the mouth and nose led to fewer errors than wider ones that stretch across the cheeks. The new study also ran tests to see whether different colored masks would affect error rates. The team used red, white, black and light blue. The research findings suggested that general

40、ly, the red and black masks led to higher failure rates than the other colors.12. How does the author mainly present the study finding?A. By giving definitions and examples.B. By giving examples and a brief description.C. By presenting data and making a comparison.D. By giving definitions and presen

41、ting data.13. According to the study, what has affected the effectiveness of facial recognition?A. The speed of the machine learning algorithms.B. The operators skill in performing algorithms.C. The number of the tested people.D. The diversity of face coverings.14. Who is the most difficult to recog

42、nize?A. A girl wearing a white round-shaped mask.B. A lady with a red mask stretching across her cheeks.C. A man wearing a light blue mask covering his mouth and nose.D. A man wearing a black mask with his nose and mouth covered up .15. What is the authors attitude towards the facial recognition sys

43、tems?A. ObjectiveB. NegativeC. Uncaring.D. Doubtful.【答案】32. C 33. D 34. B 35. A【解析】这是一篇说明文。美国政府的一项研究发现，面部识别技术在识别戴口罩的人方面正变得越来越好。【12题详解】推理判断题。根据第三段最后两句“Overall, the research shows the top-performing facial recognition systems fail to correctly identify unmasked individuals about 0. 3 percent of the ti

44、me and the failure rate rose to about 5 percent with masked images. Many of the lower performing algorithms, however, had much higher error rates with masked images as high as 20 to 50 percent.”（总的来说，研究表明，表现最好的面部识别系统不能正确地识别出大约0. 3%个未被蒙面的人。而在使用蒙面图像的情况下，失败率上升到5%左右。然而，许多表现较差的算法，对蒙面图像的错误率要高得多高达20%到50%。）

45、可知，作者主要通过提供数据和对比的方式来呈现研究结果。故选C。【13题详解】细节理解题。根据最后一段倒数第三句“The new study also ran tests to see whether different colored masks would affect error rates. ”（这项新研究还进行了测试，看不同颜色的口罩是否会影响错误率。）和倒数第四句“The study also found round-shaped masks which cover only the mouth and nose led to fewer errors than wider ones

46、 that stretch across the cheeks.”（研究还发现，圆形口罩(只覆盖嘴和鼻子)比宽口罩(覆盖脸颊)产生的错误要少。）可知，口罩的多样性影响面部识别的有效性。故选D。【14题详解】推理判断题。根据最后一段最后一句“The research findings suggested that generally, the red and black masks led to higher failure rates than the other colors.”（研究结果表明，一般来说，红色和黑色面具比其他颜色的面具失败率更高。）和倒数第四句“The study also

47、found round-shaped masks which cover only the mouth and nose led to fewer errors than wider ones that stretch across the cheeks.”（研究还发现，圆形口罩(只覆盖嘴和鼻子)比宽口罩(覆盖脸颊)产生的错误要少。）可知，一位戴着红色宽口罩的女士会最难识别。故选B。【15题详解】推理判断题。全文只是介绍了对人脸识别系统的研究，并没有表达作者的个人观点，所以作者对人脸识别系统持客观态度。故选A。第二节(共5小题；每小题2.5分， 满分12.5分)阅读下面短文， 从短文后的选项中
