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.

Of course the boy is not satisfied (对……满意) with them.
One day Mike read something about the electric lights and was   9   them. When his father told him to do housework, he went on（继续）thinking  10   it. He asked him   11   questions, and his father answered all. Then his father said proudly（自豪地），“Fathers always know   12   than sons!” The boy thought for a while and said, “  13   .” “Oh, why?” Mike didn't answer but asked. “  14    invented（发明） the electric lights?” “Thomas Edison.” answered Mr. Jackson “Why didn't his father invent them then?” Mike asked again.
Looking at his son, Mr. Jackson didn't know   15   to answer.
