cur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.

People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.

Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize enormous amounts of information", says James Foard, associate director of National Institute on Aging. "Most of us don't need that kind of skills. Such specific training is of less interest than being able to maintain mental alertness." Foard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.

Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says, "Intellectual activity actually influences brain-cell health and size."

When people are engaged in a mental activity, they ______.

A．become much wiser

B．are generally happier

C．will be more careful about what they are doing

D．will have a good memory

听力原文： I was recently working with some sixth form. comprehensive school students, when a television company asked for permission to come in and make a short film of our activities. The arrival of the cameras and crew was a major event. The setting up of the equipment, the conversion of the classroom into a mini-studio, and the sheer presence of so many television personnel (10 in all) all made this into a special occasion. On the day of filming I was better prepared than usual, and chose to wear clothes which I fancied might have some visual appeal. So did the students.

The session itself was disappointing. The camera and lights were frightening to us all and even normally active students were reluctant to attempt an opinion. Every time one of them spoke, every pieced available equipment was turned towards her.

Fortunately, this was part of a program about interesting developments in education, so the director intervened in order to encourage the kind of lively responses she was looking for. "If you don't speak up and get involved." she told the students, "then you won't be on television." The effect was immediate. The students began to go over-the-top in their attempts to attract attention. When someone said something of interest the director stopped the discussion, focused the camera and lights on her and asked her to repeat it. All of my contributions to the discussion were reshot at the end, after the students had left, and cut into the final film. Nothing could have been further removed from our normal way of working.

(26)

A．Because everyone wore her best clothes.

B．Because the classroom had never been a studio.

C．Because the speaker was going to be well known.

D．Because it involved a lot of equipment and workers.
