阅读下面短文，从短文后所给各题的四个选项(A、B、C和D)中，选出可以填入空白处的最佳选项。
It was at a concert that I happened to find David. He was holding his head at a strange       as if he were stating down at something. Then the truth struck me. He was blind. The last thing he remembers      was his daughter being born. Then the world went      .
Bad luck is no stranger to this 44-year-old man. His mother died of cancer, and his weak father had to      11-year-old David to the care of the state.
Things seemed always to go from bad to      . Two years ago, his beloved guide dog pulled him out of the      of a truck. David was not hurt. The dog      .
But David does not feel sorry for himself. These are just little obstacles (障碍) you have to      in your life, he said.
He has to make a daily two-hour trip to his working place -- the X-ray department of an _     room.
It was a hard job to     . Before he got it, David was determined to escape the workshop ran by the Lighthouse, an organization      to help blind people. He wanted a job of developing X-ray film, something     , not just he, must do in the dark, including people with      eyesight. The Lighthouse called many hospitals, with no result,      they offered to pay his first three months' salary.
David works alone in a dark room that      of chemicals. He cannot wear gloves.     , he could not feel. Since this is an emergency room, lives can be put      or out of danger. His directress says she trusts him 100 percent.
He makes $20,000 a year. But his motivation (动机) goes      money. By working, I can actualize my own      . That's the most important! he said.
What a shining example for us to     !
