His parents always had him doing too much housework. But when Tom was an adult, he had more job satisfaction, a better marriage (婚姻) and was healthier. Most of all, he was far happier.These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more worthwhile lives than those who had not. "Boys who worked in the home or community gained the ability to do things well and came to feel they were useful members of society," said George Vaillant, the psychologist (心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men's mental-health (心理健康) scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problem.The relationship between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with different people, five times as likely to be well paid and 16 times less likely to have been out of job. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.【1】What do we knew about Tom?A.He got little love from his parents.B.He enjoyed his career and marriage.C.He had few friends in his childhood.D.He was disliked by others when young.【2】Vaillant's word, in Paragraph 2 serve as ________.A.a description of personal values and social valuesB.an explanation why some boys grew into happy menC.an example for parents' expectations of their childrenD.an analysis of the relationship between work and ability【3】Vaillant's team got their findings by ________.A.studying the men's mental healthB.recording the boys' effort in schoolC.comparing different sets of scoresD.deciding the men's problem-solving ability【4】What does the underlined word "sharp" mean in Paragraph 4?A.严厉的B.敏锐的C.稳定的D.明显的
