Hi Cindy,
     Please don't worry if you feel a little strange around boys. You are in the process of   1   from a little girl
into a young womman and there are   2   called hormones (荷尔蒙) that are chaIlging not only your body but
your   3  . For example, you say you used to feel at ease   4   boys and you would usually run and fight one
another for   5  . That was Cindy, the little girl. The   6   woman doesn't want to fight boys or even run with
them   7   your interests are chaIlging. That is what is making you feel strange and it is also   8   to the other
girls around you and also to the boys. Your life is   9   a different stage but you should understand that this is
(a)  10  normal, and (b) something that will pass quickly.
     I think you should again try to  11  amund boys. You can still talk with them about  12  you like including
sports, movies, web sites and celebrities (名人). I  13  that you not try to fight with them, however, because
the  14  are becoming much bigger and stronger. I think you will find that you will  15  being with boys but
that your feelings will be different from the  16  they used to be I know you are not supposed to hve a  17  
while you are still in school in China, but if you start to find some boys very handsome and you are strongly 
 18  to some of them, don't be surprised.  19 , this is all very normal. For now, you should  20  your school
work, though you will find that some boys are attracted to you. This will be a new adventure for you and my
best advice is to relax and enjoy it. 
     Good luck!
