单项选择题

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

C

When John was growing up, other kids felt sorry for him. 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.

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 productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile 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 scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

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. 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.”

What does the underlined word “sharp” probably mean in Paragraph 4?（）

A. Quick to react

B. Having a thin edge

C. Clear and definite

D. sudden and rapid

Do you want to work with people or animals or machines or tools? Do you want to work indoors or outdoors, directly serve people in need or serve people behind the scenes? These are the typical questions that a volunteer service agency would ask.

Every year, thousands and thousands of people in the west offer volunteer services. Volunteering greatly strengthens the community partly because it helps the old, the young, the weak, the sick, the disabled and the injured to overcome difficulties.

Volunteers usually help in many different ways. They may give people advice, offer friendship to the young, drive the elderly to church, counsel kids against drugs. Work as an assistant in a school or nursing home, raise funds, plant trees, help out in local libraries and do many other things.

Volunteering can be a few hours a week or a few hours a month, time during the day, evenings or weekends, either part time or full time. Anybody __________ can become a volunteer.

The art of volunteering is a process of both giving and receiving. Volunteering allows volunteers to meet new people and make new friends and mix with people from all walks of life. Volunteering is an excellent way to experiment, practice and try out new techniques and skills. It is much more effective to practice a skill than to read about it or study it in a classroom. Volunteering is a great way to develop good teamwork skills, discover your individual talents and explore career choices. Being a volunteer takes individuals on a wonderful journey and helps them learn many important things beyond their school.
