     Several days ago my family and I went sledding(雪橇)and as I watched my children climbing up the
slope (斜坡), I started thinking.
     Many people believe that most of today's social  1   are because of the "me" generation; teenagers just
care about themselves and pay no  2   to others. Some even think today's teenagers won't do anything   3  
there is something in it for them.
     Yet, while watching, I saw a    4   side of teenagers. I watched my two oldest children take my youngest by the hand to help her  5   up the slope. They would have been  6   without her,  7   not once did they try
to set off without her. And when the sled    8   my two daughters was aimed  9   the embankment (路堤), it was my five-year-old son who ran to them to stop them from falling and   10   themselves.
     Don't get me wrong; these children sometimes  11   among themselves to get the things they want. But I
can take them to the shop and know that they won't   12   anything, I can talk to them about the   13   and
know that they will offer to send some of their own money to  14   the people in the disaster area, and I
can ask them to  15   with those children left alone and know that they will do their best to befriend them.
     Perhaps it's not the "me" generation that   16   many of society's problems - not the teenagers who
want  17   ,but the adults in their lives who have taught them to  18   think only of themselves and to want
everything. Most young children want to help. We can  19   that feeling to continue into adulthood by
teaching the lesson my children learned while sledding: Life is a slippery slope, but we can all make it to the
  20  if we remember to help others.
