    About a week ago, when I was playing basketball at our local park, I noticed a small group of boys
picking on a smaller, skinnier boy. They were   1   him names and even pushed him to the ground and
kicked dirt in his face.   2   I saw that, I walked over to the group. 
    I stepped   3   them and the smaller boy, and asked them politely what this boy had done worthy of 
  4   they were doing to him. One of the boys replied, "He's weird." At that, I asked one of the boys if
he thought his friend was weird, and the   5   was "No." So, I asked another boy what the word "weird"
   6  , and he said, "Different." That was my cue (暗示). I told them that everyone is   7  , and that they
all looked just as different to the other boy as he did to them. They all stood   8   for a moment, and then
the most amazing thing happened. One of the boys helped the small boy off the ground and then said sorry
to him. He   9   to let him play with them.
    I thanked the boy for being so  10 . As I looked around, I realized that there were dozens of other people
at the park  11  no one else had stopped to help this boy. I felt happy that the boy was strong enough to
stand up against his friends to  12  someone in need, but I felt sad that  13  else had even taken a second
look.
    I hope that my action helped them  14  that they could have made a difference with a little  15 , and
maybe next time they will be the ones who choose to help.
