    Your peers are people at your age or close to it. Besides close friends,your peers include other children you know who are at the same age — like people in your grade,sports team,or neighborhood. Peers may have positive influence on each other and play important roles in each other's lives:

Positive examples

    Peers set plenty of good examples for each other. Having peers who do well in school or do their best in a sport can influence you to work hard to realize your dream,too. Peers who are kind and helpful can influence you to build these qualities in yourself. Even peers you’ve never met can be role models. For example,watching someone at your age compete in the Olympics or give a piano concert might inspire you to go after a dream of your own.

Feedback (反馈) and advice 

  Your peers can give you feedback as you try out new ideas. They can help you make decisions,too: what courses to take,whether to get your hair cut or let it grow,or how to solve a problem. Peers often give each other good advice. Your peers will be quick to tell you when they think you’re making a wrong decision or doing something dangerous.

Socializing (交际) 

   Being with your peers ——such as classmates or teammates — gives you a chance to learn how to make friends and deal with disagreements with people.

New experiences

   Your peers might get you involved (参与) in clubs,sports,or volunteer groups. Your world would be far less rich without peers encouraging you to try some new food for the first time,or listen to a CD you have never heard before.

  An 18-yek--old boy from New Jersey,Justin Beckerman,has built his own submarine (潜水艇) !

He calls it The Nautilus.

   Justin spent six months and about $ 2,000 building the submarine from the parts he found in stores or online.

    "I spent about one or two weeks designing it," Justin said in an interview. " I spent about two more weeks looking for all the parts."

    The submarine uses ballast tanks (压载舱) to stay underwater. A ballast tank is part of a submarine that holds water. It lets in water to help the submarine go down and lets water out to help the submarine go up.

    Justin also had to work out how to start the submarine. "The submarine has four battery systems (系统) 一three nain systems and one emergency (紧急情况) system,he said. The submarine's batteries allow it to move underwater for about two hours.

    Testing a machine underwater can be dangerous,so Justin's parents keep a close watch on him every time he goes down.

Justin has built other smaller submarines,but not all have been successful. One of them failed because its materials were not strong enough. But Justin kept trying,and finally built the working submarine he has now.
