When Justin Tong was a child, other kids felt sorry for him. His parents always had him doing lots of housework such as carrying out the rubbish and sending newspapers. But when he grew up, he was better off than his childhood friends and lived a happier and healthier life.

This is the finding of a 40-year study that followed the lives of 456 children in London. It showed that the children who had worked hard in childhood had a richer and a happier future. "Children who worked in the home or community gained competence(能力) and came to feel they were worthwhile members of society," said Daniel Brown, the psychologist(心理学家) who made the discovery. "And because they felt good about themselves, others felt good about them."

Brown's study followed these children in great detail. Interviews were repeated at ages 25, 31 and 47. Under Brown, the researchers compared the children's mental-health scores with their childhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

    Working at any age is important. Childhood activities help a child develop responsibility, independence, confidence and competence — the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent 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."

    As we all know there are all kinds of clubs in US middle schools, such as music club, sports club, chess club, swimming club. But do you know homework club? It is a popular club in many US middle schools. More and more students spend(花费) their afternoons at homework clubs. The US middle school students need a quiet place to study. But games, computers and TVs are all around kids at home. So the homework club is just for them to do their homework. The club is quiet and it's good for students to study. Some teachers are there, too. They can answer students' questions and help with their homework.

    After the students finish their homework, they can go home. Then they can play games or watch TV happily.

    Every night in Jinan University in Guangzhou, {#blank#}1{#/blank#}play diabolo (空竹) as a crowd watches in amazement.

    Chen Zhelun, 25, a Malaysian-Chinese started the diabolo club, which helps to increase the popularity of this traditional Chinese game. He is one of many students expressing their interest in the country's cultural heritage (遗产) by {#blank#}2{#/blank#}.

    The diabolo, which came from China, is popular among Chinese living in Malaysia.

    "We played diabolo from primary school onward. I thought I could find someone {#blank#}3{#/blank#}in China, but only a few students knew about it. So I started a club to develop it," says Chen.

    To Chen's surprise, the old game has interested a huge crowd—more than 1,000students have joined the club.

    "It {#blank#}4{#/blank#}and it's fun," says Chen.

    But some prefer quieter activities. Every weekend, one classroom in Shenzhen University is always crowded, but it's unusually silent. The members of Lanting Calligraphy Club are writing Chinese characters with traditional brushes.

    As head of the traditional Chinese local operas club, Kong Yanquan plans to put modern elements (元素) into traditional culture to get students to join his club.

    "I think it's everyone's duty {#blank#}5{#/blank#}China's traditional culture among young people," he says.
