阅读理解。 For many American teenagers, having a part-time job is an important part of growing up. A part-time job can teach teenagers important skills like responsibility (责任), independence (独立),teamwork and leadership. Young people can expand (扩大) their social circles beyond their classmates by making friends with co-workers. And many teenagers find that earning their own money gives them a sense of pride and freedom. The US Department of Labor allows teenagers to apply for jobs at the age of 14. Popular part-time jobs include working in ice cream stores, coffee shops, and clothing stores. During the school year, teenagers may go to work a few times a week after their classes get out, then work for longer on the weekends. In the summer, top jobs for teens include working at camps, swimming pools and amusement parks. These jobs are great for young people who want to be active and have fun while making money. A favorite job for many teens is babysitting (临时替人看小孩), and they can start before 14 if the parents agree. After the children are sleeping and before the parents come home, babysitters have lots of freedom. As long as they stay in the house and make sure the kids are okay, babysitters can do their homework, enjoy a snack, watch TV, or talk on the phone with friends. It can be stressful to balance school, homework, and a part-time job. Still, many American teenagers value their work experience and the skills they gain on the job. 1.
