American teens are setting an example for their parents through their volunteer work, according to the

Harris Interactive poll conducted in the United States between Jan. 29 and Feb. 2 among 2,003 adults. The

random national telephone survey released this week by the Federal Way-based charity World Vision found

that more teens volunteer to support a charitable (慈善的) cause-56 percent-than have a part-time job-39

percent.

Parents and guardians said 82 percent of the teens in their lives do something to support charitable causes,

including volunteering, recruiting others to a cause, wearing a T-shirt or donating money. Forty-six percent

of the adults surveyed said they volunteered their time and they also inspired their children to volunteer.

Sara Johnson, a teacher who advises students at a private school in a Chicago suburb, says she's seen a

rise of teen involvement in social causes since President Barack Obama was elected in November.

The Harris Interactive survey found a quarter of teens have become more involved in charitable causes or

organizations as a result of the economic downturn, but the economy has also led to cuts in allowances, and

has teens work more hours at a paying job.

Alynn Woodson, director of volunteer engagement at Habitat for Humanity International, said she has

noticed a new enthusiasm among teen volunteers for the organization.

Habitat for Humanity International celebrates the 20th anniversary of its alternative spring break program

this year and is expecting more than 12,000 young people to help build homes for low-income people around

the nation.
