His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier. [2]These are the findings of a 40year 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 productive lives than those who had not. “Boys who worked in the home or munity gained petence (能力) and came to feel they were worthwhile members of society，” said George Vaillant, the psychologist (心理學(xué)家) who made the discovery. “And because they felt good about themselves, others felt good about them.” [3]Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers pared the men’s mentalhealth scores with their boyhoodactivity scores. Points were awarded for parttime jobs, housework, effort in school, and ability to deal with problems. [4]The link 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 a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. [5]Working — at any age — is important. Childhood activities help a child develop responsibility, independence, confidence and petence — the underpinnings (基礎(chǔ)) of emotional health. They also help him understand that people must cooperate and work toward mon goals. The most petent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.” 1.提出現(xiàn)象(第1段) 童年時(shí)期幫助做家務(wù)的孩子長(zhǎng)大后更快樂。(可解46題) 2.以研究成果為例說(shuō)明該現(xiàn)象的普遍性和真實(shí)性 用數(shù)字驗(yàn)證現(xiàn)象 3.給出結(jié)論 第5段點(diǎn)明工作的重要性，童年時(shí)期的各項(xiàng)活動(dòng)能夠幫助孩子情感健康發(fā)展，這也印證了第1段提出的現(xiàn)象。(可解50題) [定區(qū)間細(xì)比對(duì)] 46．What do we know about John?
