Sending packets, shopping for everyday goods and even building a house, these are new skills that new robots show at the World Robot Exhibition.

    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."

Carol has three sisters. All of them are very beautiful. Sometimes she feels very bad because she doesn't look like them at all. She is short and heavy and she doesn't have big eyes or beautiful hair.

As young girls, her sisters often go to parties on weekends but Carol always stays at home—reading books and doing the homework. She says it's her dream to go to university(大学).

Ten years later, Carol grows up. All her sisters get married(结婚) at a young age and don't live a happy life. But Carol is now a teacher in a university and she spends most of her free time taking trips. Every day her life is colorful.

Well, you see it won't matter if you are not beautiful but you must study hard all the time. That may be the only way if you want to make your dream come true.
