One of the major problems facing nursing homes is that patients don't move around enough. All too often the elderly end up sitting and looking at a wall or into a television. They're usually not motivated (有积极性的) to exercise, partly because getting moving again after a long period of inactivity can cause pain, and partly because it's not interesting to sit and look at a wall while you bike.

A new research project from Aalborg University in Denmark may have the solution: virtual reality (VR). The project, led by Jon Ram Bruun-Pedersen, uses the technology to get the elderly on exercise bikes, thus turning exercise into a virtual experience.

In Bruun-Pedersen's study, large TV screens were set up in front of the exercise bikes in the nursing home's activity room. While they biked, the 21 seniors rode through various virtual landscapes on the TV screen. The bikes were connected with the screens so the speed the subjects biked with was related to their speed through the landscape.

"The study showed that seniors were happy with the experience and really lived it," says Bruun-Pedersen. "They felt as if they had to ride harder to get up the hill on the screen."

Next, the elderly subjects wore VR glasses with small screens in front of their eyes. The feeling is very true to life, and the elderly subjects vividly (逼真地) experienced being out in the great outdoors - even though they were still on an exercise bike in the activity room.

"We set the study up so the elderly could ride in the same landscapes they knew from the screens. They took to the experience amazingly well," Bruun-Pedersen said. "The seniors' desire to use the exercise bikes greatly increased."

"This is really good," he says. "Partly because it's good for them physically to move more, but also because I wanted them to experience getting out in the world - even if it's a virtual world."

24. According to the text, what is a reason why the elderly seldom move around?

A. They are not in good health. B. They are afraid of getting hurt.

C. Doing exercise may be painful. D. It's more interesting to watch TV.

25. What can we infer（推断）about the seniors' experience in Bruun-Pedersen's study?

A. The VR glasses helped them bike easier and faster.
