9.In America,many teenagers have a part-time job.A part-time job is one that you do a few hours each week to make money.Do you have a part-time job?
Teens can have many different kinds of part-time jobs.Some teens work in a grocery(雜貨) store bagging groceries.Others may work in other local business such as the clothes store or drag store.You may have friends who work in a fast food restaurant.They may make the food,or keep the restaurant clean.Many teens make extra money by baby-sitting younger children in the neighborhood.Some teens even have their own business.They cut grass and take care of pets in their neighborhoods while other people are on vacation.
Most teens who have part-time jobs work only a few hours after school,maybe two or three times a week.They often have to work all day on Saturday.
Having a part-time job has many advantages.The job teaches you new skills that you can use as an adult.The job also teaches you responsibility(責(zé)任). The person who paid you for the job expects you to be there when you are supposed to and to do your job well.The job also pays you money that you can use for many different things.Your family might need the money to help with the family budget(預(yù)算).If you're lucky,you could use the money to buy music and videos.You might want to save the money to buy a new bicycle or maybe even a car.
In some families,teens have pan-time jobs to help make money to go to college.Going to
college is very expensive.Many parents cannot pay for their child's education without help from the child.In some families,at least half of what a teen makes at a part-time job goes into a college
savings account(賬戶(hù)).The teen can spend the rest of the money on what he or she needs or wants.
Many teenagers have part-time jobs and still have time for their friends and families.Many still belong to clubs at school and even have time to play sports.If you have a part-time job,you need  to have a good plan to help you do everything you want and have to do.Do your homework and
chores as soon as you can.Don't let the work wait and pile up(堆積).Make sure you get to your job on time.Do the things that are most important to you.Spend time with the people you care about most.
