Researchers have established that when people are mentally engaged, biochemical changes occur 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 ______.

听力原文： Because of the severe drought which has continued this year, water rationing will go into effect on Monday. Lawns can not be watered with automatic sprinklers; driveways, porches, and dicks can not be hosed down. You may water by hand, but only on even-numbered days. Cars can be washed on Wednesdays only. The city has hired a new drought patrol crew, which will be looking for offenders. If you are caught, there will be a ＄50 fine for the first offense and a ＄100 fine for the second offense. We realize that this is strict, but the drought has affected us dramatically. We ask your cooperation in conservation water. Besides the drought roles, we ask that you be prudent in your household water use. Turn off the faucet while you brush your teeth. Take short showers; you might even consider turning off the water as you soap up. Don't wash dishes under running water, and when you wash your clothes, save the final rinse water to begin your next load. Thank you for listening. Let's all work together to save our community's water.
