    Do you know that over ten million American kids go to camp every summer?  小题1:Back then, before the air conditioner was invented, hot city summers were uncomfortable and even unhealthy for children, so escaping to the country for a few weeks became a popular trend.
    Today, kids have different reasons for making camp a part of their lives, such as:
    To meet new people
    Camp might give you a chance to be with people from different states, or even different countries. It’s a great way to make new friends and learn about different places and cultures. Michiko, 13, put it like this:“I loved camp. I met this girl name Manny who lives in New York (I live in New Jersey) and she is cool.  小题2: We taught each other words. We liked to swim in the pool a lot.”
    To challenge yourself
     小题3: Fresh challenges — like trying new sports, learning new crafts and games, or pushing yourself to achieve something — can be very rewarding. Take it from Arabella, 13, who told us: “ I went to summer camp and I passed my swimming test! I can hardly swim, so it was a big accomplishment (成就).  小题4: 
    To appreciate nature
    There’s a great big natural world out there, and going to camp helps you learn how beautiful and important it really is.  小题5: Getting out into the woods or mountains can give you a better understanding of how the web of life works.
    A.Not all the things that kids do at camp are easy.
    B.She speaks Spanish and I speak Japanese.
    C.I felt great afterwards.
    D.It’s also a great way to learn about teamwork and tolerance(包容).
    E. Summer camp has been a U.S. tradition for over 150 years.
    F. When you get right down to it, going to camp is all about having a good time.
    G. Without trees, soil, water, and wildlife, the Earth couldn’t survive.
