A business school in Paris will soon begin using artificial intelligence and facial analysis to solve the problem. The software， called Nestor， is used in two online classes at the ESG business school beginning in September. The idea， according to LCA founder Marcel Saucet, is to use the data that Nestor collects to improve the performance of both students and professors. The software uses webcams (網(wǎng)絡(luò)攝像機(jī) ) to analyze eye movements and facial expressions of the students and determines whether students are paying attention to a video lecture. It then formulates quizzes (小測(cè)驗(yàn) ) based on the content covered during moments of inattentiveness. Professors would also be able to identify moments when students’ attention waned (衰退 ), which could help to improve their teaching, Saucet says. Advocates for AI in education say that the software is actually unable to teach a course， but the technology could be used as a digital tutor that would adapt to a student’s individual needs， and help develop more effective studying habits. Such software could also help teachers by providing feedback on the effectiveness of their teaching, advocates say. Saucet says Nestor won’t store any of the video footage it gets and that his pany has no plans to sell any other data the software collects. In addition to facial recognition and analysis, the software can integrate (合并 ) with students’ calendars to suggest possible study time, and track their online behavior to pick up on patterns. Rose Luckin, a professor at the University College London Knowledge Lab, says AI could unlock the ―black box of learning‖ by providing information on how and when learning happens. Luckin says a program like Nestor could be useful for students who take classes remotely, since ―there isn’t a human there watching them‖. While some are concerned that AI may one day replace teachers， Luckin sees the technology more as an assistant， rather than a replacement. Saucet agrees. ―Human contact is not going to go away,‖ he says. ―There will always be professors.‖ 24. How does Nestor work to find out when students aren’t paying attention? A.

Nestor could help the students who take remote classes. C. AI will finally replace teachers one day in the future. D. There would be no technology without human contact. C Being physically challenged can bring about inconvenience in life. But in Lenwood Haddock’s case, being blind works to his advantage. His trained, sensitive hands can perfectly handle every step in the plicated process of weaving hammocks, which takes a sharp eye, a skilled hand and lots of patience. Since beginning his craft in 1986, Lenwood has woven about 145,000 perfect hammocks. Now 61, Lenwood lost his sight in 1973, at age 18, during a hunting accident. ―My whole working career has been blind,‖ he says. He first found a job as a woodworker, but when that anization closed, the North Carolina Division of Services for the Blind connected him with Hatteras Hammocks. On his first day of work, ―I did a total of one hammock,‖ Lenwood recalls, laughing. ―And then I came home and laid on the sofa and went to sleep. I lift weights, but I wasn’t as tough as I thought until I started weaving. It takes a lot of energy, and you’re standing up all day.‖ In time, however, Lenwood got int
