问题     Today I would like to tell you about the effects of old age on health. Actually today a lot of improvements have taken place in the care of old people and old people’s health is not nearly so bad as it used to be.
    Probably many of the fears that people have of growing old are greatly exaggerated(夸大). Most people, for example, dread becoming senile. But in fact very few people become senile Perhaps only about 15% of those over 65 become senile. Actually much more common is in fact caused by doctors ourselves. And that is over-medication. Nearly 80% of people over 65 have at least one serious illness, such as high blood pressure, heating difficulty or heart disease And very often to combat these they take a number of drugs and of course sometimes there are interactions among those drugs. And this can cause a lot of complications from mental confusions, very commonly, to disturbance of the heart rhythrn(节奏). So this is a problem that doctors have to watch out for.
    Probably the most ignored disorder among old people is depression. Maybe about 15% of older people suffer from this condition. A lot of it is caused by this over-medication which we mentioned.
    Although it is better now for old people we have to admit that the body does change as we grow older. The immune(免疫的) system starts to decline and there are changes in metabolism(新陈代谢), lungs, the senses, the brain and the skin.
    So what should an old person do to counteract these changes?
    He or she should eat a balanced diet -- not too much fat -- chicken or fish should be eaten rather than eggs or beef. Eat more high-fiber and vitamin-rich foods, such as vegetables and fruit.
    The old person should give up smoking if he hasn’t already done so. He should also do regular exercises -- at least half an hour, three times a week. No section of the population can benefit more from exercise than the elderly.
选项 A、the effects of old age on health
B、old people
C、people’s fear of getting old
D、old people’s diseases
答案A
解析 文章第一句话即是全文的主旨句：...about the effects of old age on health(老年对健康的影响)，并且后文介绍的都是老年人害怕年迈的原因及相应的解决这一问题的方法，所以[A]是正确答案。[B]所指太泛；[C]只是文章提及的一个事实；[D]也只是文章提及的部分内容。
