Hong Kong (CNN)--A Dutch artist and designer has come up with a device he hopes will suck pollutants from Beijing's smog-covered skies, creating columns of clean air for residents. An electromagnetic field caused by copper coils will pull small pieces in the smog to the ground where they can be easily cleaned. "It's like when you have a balloon which has electricity and your hair goes toward it.Same with the smog," says artist Daan Roosegaarde.His studio has reached an agreement with the Beijing government to test the technology in one of the capital's parks.With its skies regularly covered by filthy gray smog, Beijing this week announced a series of emergency measures to deal with the problem in public. Roosegaarde says an indoor experiment has already proved it works and he is confident the results--with the help of a team of scientists and engineers--can be copied outside."Beijing is quite good because the smog is quite low. It's in a valley so there's not so much wind.It's a good environment to explore this kind of thing.We'll be able to purify the air and the challenge is to get rid of the smog so you can see the sun again." Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a complete solution to Beijing's serious and terrible air pollution."This is not the real answer for smog.The real answer has to do with clean cars, different industry and different lifestyles," he says. However, he hopes the project will make a difference by allowing the city's residents to realize the difference between breathing clean and smog-filled air."I want to take a park in Beijing, 50m by 50m square, and make it the cleanest park in Beijing," he says.He is still discussing with local authorities which park will be used. Roosegaarde's studio has worked on several projects that use static electricity in unusual ways:creating a road that charges electric cars and a floor that generates electricity when danced on. Why is the project carried out in Beijing? A) Because Beijing is the most polluted city. B) Because the designer lives in Beijing. C) Because there is much wind in Beijing. D) Because the environment suits the project.

Q: An old woman diverted ( ) attention from the book when I was sitting in my car. She walked slowly towards my parked car with a large shoulder bag. She stopped and put a hand out to rest against the car. She gently closed her eyes, took a deep breath and wiped the sweat off her forehead. Was there a way I could do anything to help her? But I wondered if the lady noticed me sitting inside the car, she would feel embarrassed and walk away. I stilled my body while my mind searched for answers. I turned my head towards my driver, wanting him to ask the lady if we could give her a ride. Because of my head movement, she noticed me and moved her hand away from the car. Her calm expression changed to a cautious one. I grabbed the water bottle next to me, smile, gently opened the door and offered the bottle to her. She looked at me hesitatingly, shook her head with downcast eyes and walked away. I was so annoyed with myself. I should have been more careful not to move.

(Question)
Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated ," Edwards points out. "The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution." In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own." The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns. "At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry," Beck says. "But it's amazing how quickly we have given up that belief." "Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds." The author seems to suggest that the future robotic dogs may _ . A) keep old people active B) cure certain diseases C) change people's beliefs D) look more like real dogs
