Помогите перевести эти тексты
Steve Jones: I hire teens, because they have a lot of energy, they learn quickly and they work hard. I think after-school jobs and summer jobs are good for kids because they learn good habits: how to be on time, how to be responsible, and how to be independent. It teaches kids about working for the things they want and not just waiting for they mom and dad to buy things for them.


Joan Davis: Summer jobs are fine for high school students. But an after-school job can be problem. It a student works for too many hours, he / she sleeps during class and doesn't do any studying at home. Well, some parents think that it their child doesn't do well at school, he / she better get a job and learn something practical. Bat I don't really agree. School is more important at this age.


Maggie Martin: I'm a volunteer, which means that I work for free. During my last summer holidays I worked in a school for the blind. This was not just about making friends from around the country; it was mush more than that. It was about discovering that people have different things that are important to them, and different problems. It was about learning hom to live in a way that is best for everyone. Most of my time was spent working in Talking Book Library, but I also spent a lot of time with the students of the school. I got a bett understanding of how difficult life can be, and how people can help each other. I belive that community work is very important and I can't wait to repeat the experience next year.
