                                              Teenagers Talking About "Being a Teenager"

      Being a teenager is a strange and yet exciting part of life. We are faced with tough and important decisions

each and every day-decisions that will affect our lives. 

                                                                                                                                                 -Katie

      Being a teenager is hard. I was such a cheerful kid with a best friend and lots of good friends. I got good

marks and I was happy with my family. But since I became a teenager, things changed. Everything changed-

my family, my friends, and my grades. In fact, my whole life changed. I started worrying about my figure and

the way I looked. I started getting pimples (粉刺) all over my face. I think teenage life is harder for girls than

for boys. 

                                                                                                                                                 -Julia

      Teenage years are a time when the single decision of right and wrong is based on what we see and hear.

Peer (同伴) pressure is more and more serious, and the need to "fit in" ( 顺应,适合) sometimes is more

important than"right" decisions. 

                                                                                                                                                 -Ashley

      Me? I have so much pressure (压力)! Being the only child in the family, my parents say that my future is

the future of the family! My parents, who both have not gone to university, put all their efforts into me, hoping

I can bring honor to the family. I really don't want to let my parents down, and I'll study harder and try my

best to get into university. 

                                                                                                                                              -Chen Mei 

     Though teenagers face many difficulties, I believe that we can all enjoy our time as "young adults"

somewhere in between the tears and the anger. Just think… ten years from now when you throw your back

out and start balding (秃顶), all you'll be saying to yourself is "What I wouldn't give to be seventeen again!" 

                                                                                                                                                -Kathy
