问题     Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.
    The study shows that those living the longest are more outgoing, more active and less neurotic(神经质的)than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.
    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.
    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.
    Unfortunately, another recent study shows that your mother’s personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we’re adults, which may mean that kids of depressed moms end up dying younger.
    Personality isn’t destiny(命运), and everyone knows that individuals can learn to change. But both studies show that long life isn’t just a matter of your physical health but of your mental health.
The aim of the study in the Journal of the American Geriatrics Society is______.
选项 A、to see whether people’s personality affects their life span
B、to find out if one’s lifestyle has any effect on their health
C、to investigate the role of exercise in living a long life
D、to examine all the factors contributing to longevity
答案A
解析 推理判断题。第一段第四句提出问题：是不是一些个性可以使人们的寿命变长?最后一句接着讲到，《美国老年病学会杂志》上的一项最新研究通过调查那些寿命至少100岁的人们的246名后代的性格特点来审视这一问题。由此可见，该研究的目的就是弄清个性是否会延长人们寿命的问题，故答案为A)。
