A while ago my family and I went sledding(滑雪橇) and as I watched my children climbing up the slope I started thinking.

Many people are convinced that most of today’s   26   problems are because of the “me” generation. Youngsters are just out for themselves and pay no   27   to others or their needs. Indeed, a common belief is that today’s youngsters won’t do anything  28   there is something in it for them.

Yet, while sledding, I saw a   29  side. I watched my two oldest children (then five and four) take my youngest(then two years old)by the hand to help her up the slippery slope  30   they went up. They would have been   31  without her, but not once did they try to sneak （溜掉）by her without helping. And when the sled  32  my two daughters was aimed toward the edge, it was my five year old son who ran to them to  33  them from falling and hurting themselves.

These children sometimes   34  among themselves and, on occasion, behave horribly. But I can  35  them shopping and know that they won’t ask for anything, I can talk to them about tsunami or hurricane victims and know that they will offer to  36  some of their own money to the cause, and I can ask them to play with those children  37  on the sideline(作为旁观者) and know that they will befriend（照顾）them.

Perhaps, therefore, the “me” generation is to blame  38   much of society’s problems—not the youngsters who want everything,   39  the adults who have taught them to selfishly  40   only of themselves.

Most adults have been   41  at some time or another, sadly, many   42  that disappointment down to their children. Then the children learn to put themselves first!

Most young children want to help. We can  43  that feeling by teaching the lesson my children learned while sledding: Life is a slippery slope with  44  of bumps(撞伤) and bruises(擦伤), but we can all make it to the  45  if we remember to help those who need it.
