阅读下面短文,从短文后各题所给的四个选项(A、B、C、D)中,选出可以填入空白处的最佳选项。
It was 20 years ago. I was driving home with my 4-year-old son. Traffic was light. I was singing quietly along   36  the song playing on the radio. I   37   at the intersection(交叉路口) and looked both ways. The road was   38 . I slowly started to make a right turn when suddenly a car rounded the curve at high speed and came straight at me. I stomped (猛踩) on the brakes of my car  39 the engine in the process. The speeder zoomed (疾驰) past my dead car  40  me by inches without even slowing down.
  41  I knew it, a stream of rude words was flying from my lips,   42  after the car and its driver. I then saw my son who was staring up at me   43 . With a red face and a(an)   44  smile I started the car, pulled back onto the road, and headed home.
Later that evening I was reading a book when I heard certain  45 words coming from my son’s bedroom. He was replaying the   46  over and over in his mind. Too   47  I realized the   48  of those words that had   49  from my lips in that moment of anger. It took a lot of talks about good language and bad language with my son to undo (消除)the   50  of that incident.
That  51  , however, did teach me just how strong words  52  be. It helped me to decide to stop swearing (咒骂) in my own life and to start using words uplifting and   53   instead. I slowly realized that language is a gift from God and should be used to make our world better but not worse. I learned   54  that a few loving words can help a hurting heart, strengthen a   55  spirit, and lighten a heavy load. I pray then that all of your words today are full of love, joy, happiness, and light.
