Old age may not sound exciting. But recent findings offer good news for older people and for people worried about getting older.
Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At that time, the people were between the ages of eighteen and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The findings showed that stress levels dropped sharply after people reached their fifties.
Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
The findings appeared in the Proceedings of the National Academy of Sciences. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

(答案→)A 解析：本文叙述了研究人员发现，当人们年过50岁后，他们变得更快乐，也少了一份担心。研究人员发现，人们在85岁时的生活幸福指数比他们18岁时更高。研究人员询问了一些情感方面的问题，例如幸福、悲伤、忧虑。他们还问到了关于精神或情绪紧张的问题。研究人员表示，他们不知道为何人们变老之后幸福感会增加。其中一种理论是，随着人们逐渐变老，他们对自己拥有的更加感恩，更能够控制自己的情绪。他们用来思考不愉快的经历的时间也更少。【小题1】主旨大意题。根据全篇短文来看主要谈及的是人的年龄和幸福指数的关系，故选A。【小题2】细节理解题。根据Researchers found that people become happier and experience less worry after they reach the age of fifty. 故选D。【小题3】细节理解题。根据as people grow older, they grow more thankful for what they have 故选 B。【小题4】细节理解题。根据Researchers say they do not know why happiness increases as people get older.故选D。

就是这个解释
