School teachers and parents are always worried about whether students are paying attention in class or not. 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 (网络摄像机) 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 (小测验) 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 company 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. 中小学最新教育资料

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. By collecting the thoughts of students of the same age. B. By storing the data of students in different universities. C. By analyzing eye movements and facial expressions. D. By identifying moments when students’ attention waned. 25. Which is the benefit of AI education?

A. It helps to develop more effective studying habits. B. The software is able to teach a course in fact. C. It could be used exactly as a tutor. D. It could help recycle teachers’ teaching.

26. How does Nestor deal with the information collected from students? A. Nestor will store it.

B. It’ll be kept from being stolen.

C. The company will sell the data to other corporations. D. Nestor will use it for suggesting possible study time. 27. What can we learn from Rose Luckin’s words?

A. AI could provide information on learning or people’s needs. B. 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.

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 中小学最新教育资料

can perfectly handle every step in the complicated 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 organization 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 into a good working rhythm and found he had a gift for the job. At first he worked on-site at the company, but after a year Lenwood moved his operation to the home workshop where he’d worked for 10 years during his woodworking days.

Since Lenwood began with Hatteras Hammocks 30 years ago, the company has aquired other brands and changed its name to The Hammock Source. Today, it is the world’s largest maker and seller of hammocks, all built by hand. 28. How old was Lenwood Haddock when he began weaving hammocks? A. 18 years old. years old.

29. How did Lenwood Haddock feel after he has finished his first hammock? A. Exhausted.

C. 61 years old.

D. 31

30. Which of the following is needed in weaving hammocks? A. Poor eyesight.

B. Sensitive mind. C. Full patience.

Untrained craft. 31. What is the best title of the passage? A. The Success of the Hammock Source Company B. How to Weave Perfect Hammocks by Hand C. The Blind Craftsman Who Makes Perfect Hammocks D. How to Become a Successful Craftsman D

Although the human body is designed to move, modern lifestyles and office jobs rarely give us the chance to move around -- we’re sitting while we’re eating; we

sit in the car and we sit while we watch TV. It is common for us to sit for many hours at work.

New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk, a scientist at the University of Louisiana in the southern United States, says that sitting is ubiquitous in our lives, meaning it is something we do all the time, everywhere.

However, Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, “We can’t throw away physical activity. It’s extremely important. We have 60 years of research showing us that.”

Mr. Katzmarzyk and his colleagues are part of a new generation of researchers studying how sitting all day affects the length of life. “Studies that have assessed the relationship between sitting and mortality (死亡率) or television viewing and mortality are very rare. There’s only been a few of them, actually five or six now, in the last four or five years.” They found that cutting television time to less than two hours a day could add one point four years to life.

Luckily, change is already coming to some offices, especially in the design of desks. A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk.” A treadmill is an exercise machine that lets you walk in one place. Even some U.S. schools are beginning to experiment with desks that are part-bicycle to keep children moving. That’s one of the strategies that many companies are using now.

Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.

32. The underlined word “ubiquitous” is closest in meaning to ________．

A. dangerous

B. common

C. comfortable

D. awkward

33. Which view agrees with the opinion of Mr. Katzmarzyk?
