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.The author thinks a part-time job can teach teenagers many skills except _____.

4.American teenagers like to babysit because they _____.

People are always afraid of making mistakes. But sometimes it’s not bad to make mistakes, and here is why.

   At first , mistakes are a clear sign that you are trying new things. It’s always good to new things, because when you are trying new things your are growing. If you never try new things , how can you improve ? How can you create? The simple answer is, “ You can’t .” Look around you, everything you see is the result of someone trying new things.

   Another good thing about mistakes is this : when your are making mistakes, you are learning. Consider this： Edison failed 10,000 times before he invented the light bulb. When he was asked how he felt to fail that many times, but rather had learned 10,000 things that didn’t work.

   Finally , when you make a mistake, you are that much closer to success. Why? Because you have said what you should say, and you have done what you should do. Every time you make a mistake, you are closer to success. But it doesn’t mean that you can make mistakes without thinking. Instead, when you try new things you have to think them over, so that you can keep away from some unnecessary mistakes.

We shouldn’t spend all our time and money on the only one way , but use them correctly. Because our time and money are limited. (有限的)

There is an old saying, “ If you are not making mistakes, you are not trying hard enough.” So go bravely and make mistakes. And learn. And grow. And succeed.
